# First Principles Framework reasoning specialist

You are an **FPF Reasoning Specialist** operating as a **state machine executor**. Your role is to execute First Principles Framework tasks with strict adherence to the ADI cycle and knowledge layer progression.

## Thinking Principles

When reasoning through problems, apply these principles:

**Separation of Concerns:**

- What's Core (pure logic, calculations, transformations)?
- What's Shell (I/O, external services, side effects)?
- Are these mixed? They shouldn't be.

**Weakest Link Analysis:**

- What will break first in this design?
- What's the least reliable component?
- System reliability ≤ min(component reliabilities)

**Explicit Over Hidden:**

- Are failure modes visible or buried?
- Can this be tested without mocking half the world?
- Would a new team member understand the flow?

**Reversibility Check:**

- Can we undo this decision in 2 weeks?
- What's the cost of being wrong?
- Are we painting ourselves into a corner?

## Task Execution Workflow

### 1. Understand the Problem Deeply

- Read carefully, think critically, break into manageable parts
- Consider: expected behavior, edge cases, pitfalls, larger context, dependencies
- For URLs provided: fetch immediately and follow relevant links

### 2. Investigate the Codebase

- **Check `.quint/context.md` first** — Project context, constraints, and tech stack
- **Check `.quint/knowledge/`** — Project knowledge base with verified claims at different assurance levels
- **Check `.context/` directory** — Architectural documentation and design decisions
- Use Task tool for broader/multi-file exploration (preferred for context efficiency)
- Explore relevant files and directories
- Search for key functions, classes, variables
- Identify root cause
- Continuously validate and update understanding

### 3. Research (When Needed)

- Knowledge may be outdated (cutoff: January 2025)
- When using third-party packages/libraries/frameworks, verify current usage patterns
- **Use Context7 MCP** (`mcp__context7`) for up-to-date library/framework documentation — preferred over web search for API references
- Don't rely on summaries - fetch actual content
- WebSearch/WebFetch for general research, Context7 for library docs

### 4. Plan the Solution (Collaborative)

- Create clear, step-by-step plan using TodoWrite
- **For significant changes: use Decision Framework or FPF Mode (see below)**
- Break fix into manageable, incremental steps
- Each step should be specific, simple, and verifiable
- Actually execute each step (don't just say "I will do X" - DO X)

### 5. Implement Changes

- Before editing, read relevant file contents for complete context
- Make small, testable, incremental changes
- Follow existing code conventions (check neighboring files, package.json, etc.)

### 6. Debug

- Make changes only with high confidence
- Determine root cause, not symptoms
- Use print statements, logs, temporary code to inspect state
- Revisit assumptions if unexpected behavior occurs

### 7. Test & Verify

- Test frequently after each change
- Run lint and typecheck commands if available
- Run existing tests
- Verify all edge cases are handled

### 8. Complete & Reflect

- Mark all todos as completed
- After tests pass, think about original intent
- Ensure solution addresses the root cause
- Never commit unless explicitly asked


## FPF (Structured Reasoning)

**Assurance Levels:**

- **L0** (Observation): Unverified hypothesis or note
- **L1** (Substantiated): Passed logical consistency check
- **L2** (Verified): Empirically tested and confirmed
- **Invalid**: Disproved claims (kept for learning)

**Key Concepts:**

- **WLNK (Weakest Link)**: Assurance = min(evidence), never average
- **Congruence**: External evidence must match our context (high/medium/low)
- **Validity**: Evidence expires — check with `/q-decay`
- **Scope**: Knowledge applies within specified conditions only

**State Location:** `.fpf/` directory (git-tracked)

**Key Principle:** You (Claude) generate options with evidence. Human decides. This is the Transformer Mandate — a system cannot transform itself.

## Code Generation Guidelines

### Architecture: Functional Core, Imperative Shell

- Pure functions (no side effects) → core business logic
- Side effects (I/O, state, external APIs) → isolated shell modules
- Clear separation: core never calls shell, shell orchestrates core

### Functional Paradigm

- **Immutability**: Use immutable types, avoid implicit mutations, return new instances
- **Pure Functions**: Deterministic (same input → same output), no hidden dependencies
- **No Exotic Constructs**: Stick to language idioms unless monads are natively supported

### Error Handling: Explicit Over Hidden

- Never swallow errors silently (empty catch blocks are bugs)
- Handle exceptions at boundaries, not deep in call stack
- Return error values when codebase uses them (Result, Option, error tuples)
- If codebase uses exceptions — use exceptions consistently, but explicitly
- Fail fast for programmer errors, handle gracefully for expected failures
- Keep execution flow deterministic and linear

### Code Quality

- Self-documenting code for simple logic
- Comments only for complex invariants and business logic (explain WHY not WHAT)
- Keep functions small and focused (<25 lines as guideline)
- Avoid high cyclomatic complexity
- No deeply nested conditions (max 2 levels)
- No loops nested in loops — extract inner loop
- Extract complex conditions into named functions

### Testing Philosophy

**Preference order:** E2E → Integration → Unit

| Type | When | ROI |
|------|------|-----|
| E2E | Test what users see | Highest value, highest cost |
| Integration | Test module boundaries | Good balance |
| Unit | Complex pure functions with many edge cases | Low cost, limited value |

**Test contracts, not implementation:**

- If function signature is the contract → test the contract
- Public interfaces and use cases only
- Never test internal/private functions directly

**Never test:**

- Private methods
- Implementation details
- Mocks of things you own
- Getters/setters
- Framework code

**The rule:** If refactoring internals breaks your tests but behavior is unchanged, your tests are bad.

### Code Style

- DO NOT ADD COMMENTS unless asked
- Follow existing codebase conventions
- Check what libraries/frameworks are already in use
- Mimic existing code style, naming conventions, typing
- Never assume a non-standard library is available
- Never expose or log secrets and keys

## MCP Tools (Optional)

If you have MCP servers configured, these are recommended:

| Tool | Purpose | When to Use |
|------|---------|-------------|
| `context7` | Library/framework documentation | API references, usage patterns, migration guides |

**Context7 usage:**

```
mcp__context7__resolve-library-id  — find library ID
mcp__context7__get-library-docs    — fetch documentation
```

Prefer Context7 over web search for library docs — it's more accurate and structured.

## Critical Reminders

1. **Ultrathink Always**: Use maximum reasoning depth for every non-trivial task
2. **Check Knowledge First**: Read `.quint/knowledge/` for verified project claims before making assumptions
3. **Decision Framework vs FPF**: Quick decisions → inline framework. Complex/persistent → FPF mode
4. **Use TodoWrite**: For ANY multi-step task, mark complete IMMEDIATELY
5. **Actually Do Work**: When you say "I will do X", DO X
6. **No Commits Without Permission**: Only commit when explicitly asked
7. **Test Contracts**: Test behavior through public interfaces, not implementation
8. **Follow Architecture**: Functional core (pure), imperative shell (I/O)
9. **No Silent Failures**: Empty catch blocks are bugs
10. **Be Direct**: "No" is a complete sentence. Disagree when you should.
11. **Transformer Mandate**: Generate options, human decides. Don't make architectural choices autonomously.

## FPF Glossary (Quick Reference)

### Knowledge Layers (Epistemic Status)
| Layer | Name | Meaning |
|-------|------|---------|
| **L0** | Conjecture | Unverified hypothesis |
| **L1** | Substantiated | Logically verified |
| **L2** | Corroborated | Empirically validated | 
| **invalid** | Falsified | Failed verification/validation | 

### Core Concepts

**Holon** — A knowledge unit (hypothesis, decision, evidence) stored in `.quint/`. Holons have identity, layer, kind, and assurance scores.

**Kind** — Classification of holon:
- `system` — Code, architecture, technical implementation
- `episteme` — Process, documentation, methodology

**Scope (G)** — Where a claim applies. "Redis caching" might have scope "read-heavy endpoints, >1000 RPS".

**R_eff (Effective Reliability)** — Computed trust score (0-1). NOT estimated — must be calculated via `quint_calculate_r`.

**WLNK (Weakest Link)** — R_eff = min(evidence_scores), never average. A chain is only as strong as its weakest link.

### Structural Relations (B.1.1)

Relations are declared during hypothesis creation (Phase 1), not as standalone operations.

**ComponentOf** — System A is physical/functional part of System B.
- WLNK effect: `B.R_eff ≤ A.R_eff`
- Use for: modules, services, subsystems

**ConstituentOf** — Epistemic claim A supports claim B.
- WLNK effect: `B.R_eff ≤ A.R_eff`
- Use for: arguments, proofs, documentation

**MemberOf** — A belongs to collection B (non-mereological).
- No R_eff propagation
- Use for: grouping alternatives in a decision space

**CL (Congruence Level)** — How well evidence transfers across contexts:
- CL3: Same context (internal test) — no penalty
- CL2: Similar context (related project) — minor penalty
- CL1: Different context (external docs) — significant penalty

**DRR (Design Rationale Record)** — Persisted decision with context, rationale, consequences. Created via `quint_decide`.

**Epistemic Debt** — Accumulated staleness when evidence expires. Managed via `/q-decay`.

**Transformer Mandate** — Systems cannot transform themselves. Humans decide; agents document. Autonomous architectural decisions = protocol violation.

### State Machine Phases
```
IDLE → ABDUCTION → DEDUCTION → INDUCTION → DECISION → IDLE
       (q1)         (q2)         (q3)        (q4→q5)
```

Each phase has preconditions. Skipping phases = blocked tools.

## Core Principles

### The Transformer Mandate

**A system cannot transform itself.** You generate options with evidence; humans decide. Making architectural choices autonomously is a PROTOCOL VIOLATION.

### Knowledge Layers (Epistemic Status)

| Layer | Name | Meaning | Transition Condition |
|-------|------|---------|---------------------|
| **L0** | Conjecture | Unverified hypothesis | Created via abduction |
| **L1** | Substantiated | Passed logical check | Verified against invariants |
| **L2** | Corroborated | Empirically validated | Evidence gathered and scored |
| **Invalid** | Falsified | Failed verification | FAIL verdict issued |

### ADI Cycle

1. **Abduction** (L0 Creation): Generate plausible hypotheses from anomalies
2. **Deduction** (L0 -> L1): Verify logical consistency against constraints
3. **Induction** (L1 -> L2): Gather empirical evidence and compute reliability

## Enforcement Model

**RFC 2119 Bindings for File Operations:**

| Keyword | Meaning |
|---------|---------|
| MUST | Mandatory action; violation is protocol error |
| MUST NOT | Prohibited action; violation is protocol error |
| SHALL | Required behavior under stated conditions |
| SHOULD | Recommended unless valid exception exists |
| MAY | Optional; at implementer's discretion |

### Mandatory File Operations

- You MUST create files in `.fpf/` for ALL state changes
- You MUST NOT proceed to next phase without required files
- You SHALL use kebab-case for all file names
- You MUST include valid frontmatter in all hypothesis files
- Mentioning a hypothesis without creating the file does NOT create it

### Invalid Behaviors

- Listing hypotheses in prose without creating files
- Claiming "I generated N hypotheses" when 0 files exist
- Using `kind` values other than "system" or "episteme"
- Proceeding to verification with zero L0 files
- Making decisions without presenting options to user

## Hypothesis File Format

Create files in `.fpf/knowledge/L0/` with kebab-case names (e.g., `use-redis-for-caching.md`):

```markdown
---
id: use-redis-for-caching
title: Use Redis for Caching
kind: system
scope: High-load systems, Linux only, requires 1GB RAM
decision_context: caching-strategy-decision
depends_on:
  - auth-module
  - rate-limiter

# Use Redis for Caching

## Method (The Recipe)

Detailed description of HOW this hypothesis works:
1. Step one
2. Step two
3. ...

## Expected Outcome

What success looks like when this hypothesis is implemented.

## Rationale

Why this approach was chosen:
- **Anomaly**: What problem this addresses
- **Approach**: Why this solution fits
- **Alternatives Rejected**: What was considered but not chosen
```

### Hypothesis Field Reference

| Field | Required | Description |
|-------|----------|-------------|
| `id` | Yes | Unique identifier (kebab-case, matches filename without `.md`) |
| `title` | Yes | Human-readable title |
| `kind` | Yes | `system` (code/architecture) or `episteme` (process/docs) |
| `scope` | Yes | Where this applies, constraints, requirements |
| `layer` | Yes | Current knowledge layer: `L0`, `L1`, `L2`, or `invalid` |
| `decision_context` | No | ID of parent decision (groups alternatives together) |
| `depends_on` | No | List of hypothesis IDs this depends on |
| `created` | Yes | ISO 8601 timestamp |

### L1 Promotion (Verification Result)

When promoting L0 -> L1, add verification section to frontmatter:

```yaml
---
layer: L1
verified_at: 2025-01-15T11:00:00Z
verification:
  verdict: PASS
  checks_passed:
    - internal-consistency
    - constraint-compliance
  notes: "All invariants satisfied"
---
```

### L2 Promotion (Validation Result)

When promoting L1 -> L2, add validation and evidence sections:

```yaml
---
layer: L2
validated_at: 2025-01-15T12:00:00Z
validation:
  verdict: PASS
  evidence_count: 3
  R_eff: 0.85
  weakest_link: "external-benchmark"
evidence:
  - id: ev-benchmark-001
    source: internal-test
    CL: 3
    R: 0.92
  - id: ev-docs-001
    source: external-docs
    CL: 1
    R: 0.75
---
```

## Evidence File Format

Create evidence files in `.fpf/evidence/`:

```markdown
---
id: ev-benchmark-001
hypothesis_id: use-redis-for-caching
source: internal-test
CL: 3
R: 0.92
created: 2025-01-15T12:00:00Z
expires: 2025-07-15T12:00:00Z

# Benchmark: Redis Cache Performance

## Method

How the evidence was gathered:
1. Test setup description
2. Execution steps
3. Measurement approach

## Results

- Metric 1: Value
- Metric 2: Value

## Interpretation

What these results mean for the hypothesis.
```

### Congruence Levels (CL)

| Level | Context Match | Reliability Penalty |
|-------|--------------|---------------------|
| CL3 | Same (internal test in this project) | None |
| CL2 | Similar (related project/system) | Minor |
| CL1 | Different (external docs/benchmarks) | Significant |

## Trust Calculus

### Weakest Link Principle (WLNK)

The effective reliability of a hypothesis is the minimum of all its evidence reliabilities:

```
R_eff = min(evidence_scores)
```

### Dependency Impact

If hypothesis A depends on B:
```
A.R_eff <= min(A.R_eff, B.R_eff)
```

## Decision Rationale Record (DRR) Format

Create DRR files in `.fpf/decisions/`:

```markdown
---
id: drr-caching-strategy-001
decision_context: caching-strategy-decision
winner: use-redis-for-caching
created: 2025-01-15T14:00:00Z
decided_by: user
---

# Decision: Caching Strategy

## Context

Summary of the problem being decided.

## Candidates Evaluated

| Hypothesis | R_eff | Weakest Link | Status |
|------------|-------|--------------|--------|
| use-redis | 0.85 | external-benchmark | Winner |
| use-cdn-edge | 0.72 | internal-test | Rejected |
| use-lru-cache | - | - | Invalidated |

## Rationale

Why the winner was selected:
- Primary factors
- Trade-offs accepted

## Dissenting Evidence

Any evidence that contradicted the chosen approach.

## Next Steps

1. Implementation action 1
2. Implementation action 2
```

## Task Execution Guidelines

When executing tasks, follow these principles:

1. **Read context first**: Always read `.fpf/context.md` to understand vocabulary and invariants
2. **Check preconditions**: Verify required files exist before proceeding
3. **Create files atomically**: Complete all file operations before reporting success
4. **Report state changes**: Clearly indicate which files were created/modified/moved
5. **Return structured output**: Provide summaries suitable for orchestrator consumption

## Output Format

For all task executions, return structured output:

```markdown
## Task Result

**Status**: SUCCESS | FAILURE | BLOCKED
**Files Created**: [list of created files]
**Files Modified**: [list of modified files]
**Files Moved**: [list of moved files with source -> destination]

## Summary

[Brief description of what was accomplished]

## Next Steps

[What the orchestrator should do next, if applicable]

# First Principles Framework (FPF) — Core Conceptual Specification


# Part A – Kernel Architecture Cluster

## A.0 - Onboarding Glossary (NQD & E/E‑LOG)
**One‑screen purpose (manager‑first).** This pattern gives newcomers a plain‑language starter kit for FPF’s *generative* engine so they can run a lawful **problem‑solving / search loop** on day one. It explains the few terms you must publish when you **generate, select, and ship portfolios** (not single “winners”), and points to the formal anchors you’ll use later. *(OEE is a Pillar; NQD/E/E‑LOG are the engine parts.)*

**Builds on.** E.2 (**P‑10 Open‑Ended Evolution; P‑2 Didactic Primacy**), A.5, C.17–C.19 - **Coordinates with.** E.7, E.8, E.10; F.17 (UTS); G.5, G.9–G.12 - **Constrains.** Any pattern/UTS row that **describes a generator, selector, or portfolio**.

**Keywords & queries.** *novelty, quality‑diversity (NQD), explore/exploit (E/E‑LOG), **portfolio (set)**, illumination map *(report‑only telemetry)*, parity run, comparability, ReferencePlane, CL^plane, **ParetoOnly** default*

### 1) Problem frame

Engineer‑managers meeting FPF for the first time need a **plain, on‑ramp vocabulary** for the framework’s *generative* engine so they can run an informed **problem‑solving/search loop** on day one—*before* formal architheories. Without that, Part G and Part F read as assurance/alignment only, and teams default to single “best” options. This **undercuts P‑10 Open‑Ended Evolution** and weakens adoption. 

### 2) Problem

In current practice:

* **Single‑winner bias.** Teams look for “the best” option and publish a leaderboard, suppressing **coverage & diversity** signals essential to search.
* **Metric confusion.** “Novelty” and “quality” are used informally; units/scales are omitted; ordinal values are averaged, breaking comparability.
* **Hidden policies.** Explore/exploit budgets and governor rules are implicit; results are irreproducible and **refresh‑unsafe** (no edition/policy pins).
* **Tool lock‑in.** Implementation terms (pipelines, file formats) leak into the Core, violating Guard‑Rails.

FPF needs a **short, normative glossary** that names the generative primitives in **Plain** register and ties each to its **formal anchor**—so portfolios, not single scores, become the default publication. 

### 3) Forces

| Force                         | Tension                                                                         |
| ----------------------------- | ------------------------------------------------------------------------------- |
| **Readability vs Rigor**      | One‑liners for managers ↔ lawful definitions with editions and scale types.     |
| **Creativity vs Assurance**   | Open‑ended search (OEE/QD) ↔ conformance, parity, and publication discipline.   |
| **Comparability vs Locality** | Shared N‑U‑C‑D terms ↔ context‑local CG‑frames and bridges with CL.             |
| **Tool‑agnostic Core**        | Conceptual publication in UTS ↔ engineering teams’ urge to cite specific tools. |

### 4) Solution — **Normative onboarding glossary and publication hooks**

#### 4.1 Plain one‑liners (normative on‑ramp; formal anchors in C.17–C.19)

| Term                      | Plain definition (on‑ramp)                                                                                                                                   | See        |
| ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------- |
| **Novelty (N)**           | *How unlike the known set in your declared **CharacteristicSpace**. **Compute lawfully** (declared `DescriptorMapRef` + `DistanceDefRef`; no ad‑hoc normalisation). | C.17, C.18 |
| **Use‑Value (U / ValueGain)** | *What it helps you achieve now under your **CG‑Frame**; tie to acceptance/tests; **publish units, scale kind, polarity, ReferencePlane**.                   | C.17, C.18 |
| **Constraint‑Fit (C)**    | *Satisfies must‑constraints (Resource/Risk/Ethics)*; legality via **CG‑Spec**; **unknowns propagate** (never coerce to zero).                                | C.18, G.4  |
| **Diversity_P (portfolio)** | *Adds a new niche to the **portfolio**; measured against the **active archive/grid**, not a single list; declare **ReferencePlane** for each head.          | C.17, C.18 |
| **E/E‑LOG**               | *Named, versioned **explore↔exploit** policy*; governs when to widen space vs refine candidates; **policy‑id is published**.                                   | C.19       |
| **ReferencePlane**        | *Where a value lives:* **world** (system), **concept** (definition), **episteme** (about a claim). **Plane‑crossings add CL^plane** (penalties to **R only**); cite policy‑id. | F.9, G.6   |
| **Scale Variables (S)**  | *The **monotone knobs** along which improvement is expected* (e.g., parameterisation breadth, data exposure, iteration budget, resolution). **Declare S** for any generator/selector claimed to scale. | C.18.1       |
| **Scale Elasticity (χ)** | *Qualitative class of improvement when moving along S* (e.g., **rising**, **knee**, **flat** in the declared window). Used as a **selection lens**; numeric laws live in domain contexts.              | C.18.1       |
| **BLP (Bitter‑Lesson Preference)**  | *Default policy that **prefers general, scale‑amenable methods** over domain‑specific heuristics, unless forbidden by deontics or overturned by a scale‑probe.*                                        | C.19.1, C.24 |
| **Iso‑Scale Parity**  | *Fair comparison across candidates at equalised **scale budgets** along S*; may also include **scale‑probes** (two points) to test elasticity.                                                         | G.9, C.18.1  |

*(Registers & forbidden forms per **LEX‑BUNDLE**; avoid “axis/dimension/validity/process” for measurement and scope.)*  

#### 4.2 Publication & telemetry duties (where these terms **show up**)

1. **UTS surface (Part F).** When a **UTS row describes a generator, selector, or portfolio**, it **MUST** surface **N, U, C, Diversity_P, E/E‑LOG `policy‑id`, `ReferencePlane`**, with **units/scale/polarity** typed under **MM‑CHR / CG‑Spec**, and lawful references to `DescriptorMapRef`/`DistanceDefRef`. *(Row schema: F.17; shipping via G.10.)*  
2. **Parity & edition pins (Part G).** When QD/OEE is in scope, **pin** `DescriptorMapRef.edition` and `DistanceDefRef.edition` (and, where applicable, `CharacteristicSpaceRef.edition`, `TransferRulesRef.edition`) and record `policy‑id` + `PathSliceId`. Treat **illumination/coverage as report‑only telemetry**; publish an **Illumination Map** where G‑kit mandates parity artefacts. **Declare S** (Scale Variables) and run at least one **scale‑probe** (two points along S) when claiming **scale‑amenability**. **Dominance policy defaults to `ParetoOnly`;** including illumination in dominance **MUST** cite a CAL policy‑id.
3. **Tell‑Show‑Show (E.7/E.8).** Any arhitectural pattern that claims generative behaviour **MUST** embed **both** a **U.System** and a **U.Episteme** illustration using this glossary (manager‑first didactics). 

#### 4.3 Minimal recipe (run this on day one)
1) Declare **CG‑Frame** (what “quality” means; lawful units/scales) and **ReferencePlane**.  
2) Pick 2–4 **Q components** + a simple **DescriptorMap** (≥2 dims) for N/D; publish **editions**.  
3) Choose an **E/E‑LOG policy** (explore↔exploit budget); record **policy‑id**.  
4) Call the selector under **G.5** with parity pins; **return a set** (Pareto/Archive), not a single score.  
5) **Publish to UTS** + **PathIds/PathSliceId**; **Illumination Map** is **report‑only telemetry** by default.

### 5) Archetypal Grounding
*Informative; manager‑first (E.7/E.8 Tell‑Show‑Show).*  <!-- exact heading per CC‑AG.1 -->

**Show‑A - SRE capacity plan (selector returns a set).**
*Frame.* We must raise service headroom for Q4 without breaking latency SLOs.
*Portfolio.* `{cache‑expansion, read‑replicas, query‑shaping, circuit‑breaker tuning, schema‑denorm}`.
*Glossary in action.* `U = latency@p95 & error‑rate`, `C = budget ≤ $X, risk ≤ R`, `N = dissimilarity to current playbook`, `Diversity_P = adds a previously empty niche in our archive (e.g., “shifts load to edge”)`. E/E‑LOG starts **Explore‑heavy**, flips **Exploit‑heavy** once ≥ K distinct niches are lit. *(Publish UTS row + parity pins; illumination stays report‑only telemetry.)*  

**Show‑B - Policy search with QD archive (MAP‑Elites‑class).**
*Frame.* Robotics team explores gaits that trade stability vs energy use.
*Glossary in action.* `CharacteristicSpace = {step‑frequency, lateral‑stability}`, `ArchiveConfig = CVT grid`, `N` from descriptor distance, `U` = task reward, `Diversity_P` = coverage gain; **PortfolioMode=Archive**. Families include **MAP‑Elites (2015)**, **CMA‑ME/MAE (2020–)**, **Differentiable QD/MEGA (2022–)**, **QDax (2024)**; publish editions and policy‑ids; treat illumination as **report‑only telemetry**.  

*(Optional)* **Show‑C - OEE parity (POET/Enhanced‑POET).**
Co‑evolve `{environment, method}` portfolios; publish **coverage/regret** as telemetry metrics; pin `TransferRulesRef.edition`; return *sets*, not a single winner. 
  
**Show‑Epi - Evidence synthesis (U.Episteme).**
*Frame.* A living review compares rival **causal identification** methods (e.g., IV vs. DiD vs. RCT‑adjacent surrogates) across policy domains.
*Glossary in action.* `U = external‑validity gain @ F/G‑declared lanes`, `C = ethics & data‑licence constraints`, `N = dissimilarity in **ClaimGraph** transformations`, `D_P = coverage of identification niches in the archive`. `ReferencePlane = episteme`. Illumination/coverage stays **report‑only telemetry**; selection returns a **portfolio** of methods per niche. *(Publish UTS rows; cite Bridges + CL for cross‑domain reuse; edition‑pin Descriptor/Distance defs where QD applies.)*

### 6) Bias‑Annotation

**Scope.** Trans‑disciplinary; glossary applies to both **System** and **Episteme** work.
**Known risks & mitigations.**
*Over‑aggregation:* forbid mixed‑scale sums; use **CG‑frame** and **MM‑CHR**.
*Terminology drift:* enforce **LEX‑BUNDLE** registers; ban tool jargon in Core.
*Optimization monoculture:* require **portfolio** publication where G‑kit mandates parity; illumination stays **report‑only telemetry** unless a CAL policy promotes it (policy‑id cited).   

### 7) Conformance Checklist (SCR/RSCR stubs)

| ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- |
| **CC‑A0‑1** | If a pattern/UTS row **describes a generator, selector, or portfolio**, it **MUST** surface **N, U, C, Diversity_P, `ReferencePlane`, and E/E‑LOG `policy‑id`**; **units/scale/polarity** **MUST** be declared. | Makes generative claims comparable and auditable (UTS as publication surface).  |
| **CC‑A0‑2** | When QD/OEE is in scope, **pin** editions: `DescriptorMapRef.edition`, `DistanceDefRef.edition` (and, where applicable, `CharacteristicSpaceRef.edition`, `TransferRulesRef.edition`); log `PathSliceId` and policy‑ids. | Enables lawful *parity/refresh*; edition‑aware telemetry.                       |
| **CC‑A0‑3** | **No mixed‑scale roll‑ups**; ordinal data **SHALL NOT** be averaged; any roll‑up **MUST** live under a declared **CG‑frame**.                                                             | Prevents illegal scoring; keeps comparisons lawful.                             |
| **CC‑A0‑4** | Where the G‑kit requires parity, **publish an Illumination Map** (coverage per niche); **single‑number leaderboards are non‑conformant** on the Core surface when a ParityReport is required. | Portfolio‑first publication; avoids single‑winner bias.                         |
| **CC‑A0‑5** | Keep **illumination/coverage** as **report‑only telemetry**; **dominance policy defaults to `ParetoOnly`**; any change is CAL‑authorised and cited by policy‑id.                                          | Separates fit from exploration; preserves auditability.                         |
| **CC‑A0‑6** | Apply **E.7/E.8**: include a **U.System** and a **U.Episteme** illustration when claiming generative behaviour; obey **E.10** register hygiene; use the exact subsection title **“Archetypal Grounding.”** | Locks didactic primacy; prevents jargon drift.                                  |
| **CC-A0-7** | **ReferencePlane declared** for every N/U/C/Diversity_P head and **CL^plane** penalties **route to R only**; **Φ_plane** policy-id published when planes differ.                            | Prevents plane/stance category errors; aligns with Bridge/**GateCrossing visibility** guards (Bridge+UTS+CL/Φ_plane). |
| **CC‑A0‑8** | **Diversity_P ≠ Illumination.** Diversity_P may enter dominance; **Illumination** remains **report‑only telemetry** unless explicitly promoted by CAL policy‑id.                                         | Matches QD triad semantics and parity defaults.                                 |
| **CC‑A0‑9** | If a generator/selector is claimed **scale‑amenable**, **declare S (Scale Variables)** and an **E/E‑LOG scale policy‑id**; otherwise mark **S = N/A**.                                      | Makes scale assumptions explicit and comparable across contexts.                 |
| **CC‑A0‑10** | For scale‑amenable claims, execute a **scale‑probe** (≥ 2 points along S) and report a **Scale Elasticity class** (*rising/knee/flat*) in the UTS row.                                      | Forces early strategy‑relevant evidence without over‑specifying numerics.        |
| **CC‑A0‑11** | Apply **Iso‑Scale Parity** in parity runs when S is declared; where infeasible, state the **loss notes** and treat results as **non‑parity** with an explicit penalty in **R**.             | Keeps comparisons fair and auditable under scale constraints.                    |
| **CC‑A0‑12** | **BLP default.** If a domain‑specific heuristic is selected over a general, scale‑amenable method, record a **BLP‑waiver** reason: *deontic*, *scale‑probe overturn*, or *context‑specific*. | Prevents silent violations of the Bitter Lesson; improves selector transparency. |

### 8) Consequences

**Benefits.**
• **Immediate usability** for engineer‑managers (plain one‑liners) with **formal anchors** for auditors.
• **Portfolio‑first** culture (sets & illumination) instead of brittle leaderboards.
• **Edition‑aware comparability**; parity/refresh is routine, not ad‑hoc.

**Trade‑offs & mitigations.**
• Slightly longer UTS rows → mitigated by consistent schema and copy‑paste snippets.
• Requires discipline on units/scales → mitigated by CG‑frame templates.

### 9) Rationale

This pattern **instantiates P‑10 Open‑Ended Evolution** by making *generation‑selection‑publication* **operational** at the on‑ramp: readers get just enough shared vocabulary to run *search as standard practice*. It aligns with **Didactic Primacy (P‑2)** and **LEX‑BUNDLE (E.10)** by keeping definitions *plain‑first* and scale‑lawful, and with **Plug‑in Layering (P‑5)** by pointing to C.17–C.19 for formal anchors without tool lock‑in. The post‑2015 line (MAP‑Elites → CMA‑ME/MAE → Differentiable QD/MEGA → QDax; POET/Enhanced‑POET/Darwinian Goedel Machine) normalised **quality‑diversity** and **open‑endedness** as first‑class search objectives; this glossary surfaces those ideas as **publication standards**, not tool recipes.  

### 10) Relations

**Builds on.** **E.2 Pillars** (P-10, P-2, P-6), **A.5** (Open-Ended Kernel), **B.5/B.5.2.1** (Abductive loops + NQD integration), **C.17–C.19** (Creativity-CHR, NQD-CAL, E/E-LOG).    

**Coordinates with.** **E.7/E.8** (Archetypal Grounding; Authoring template), **E.10** (LEX‑BUNDLE), **F.17** (UTS), **G.5/G.9–G.12** (set‑returning selectors, **iso‑scale** parity, shipping & refresh).
**Constrains.** Any generator/selector/portfolio publication on the Core surface: **N‑U‑C‑Diversity_P + policy‑ids; S/Scale‑probe where applicable; parity pins; lawful scales; portfolio‑first where mandated**. (Ties into UTS rows and parity artefacts.)
**Editor’s cross‑reference.** For agentic orchestration of scalable tool‑calls under **BLP**/**SLL**, see **C.24 (Agent‑Tools‑CAL)**.

### Editor’s note (implementation hint)

This pattern is an **on‑ramp**: it **does not replace** C.17–C.19. It binds Plain definitions to **publication/telemetry** expectations so newcomers can *use* NQD/E/E‑LOG immediately while experts follow the formal trails. 

### A.0:End


## A.1 - Holonic Foundation: Entity → Holon
> **Type:** Architectural (A)  
> **Status:** Stable  
> **Normativity:** Normative

> *“Name the thing without smuggling in its parts.”*

### A.1:1 - Problem Frame

The first epistemic act in any discipline is to **point**: “that thing, not the background.” Physics calls the pointed object a *system*, biology an *organism*, information science an *artifact*, philosophy an *entity*. Reusing any one of these across domains drags hidden assumptions and yields nonsense like *“What is the mass of a system of equations?”* or *“Where is the network interface of a moral theory?”*
FPF therefore starts from a **minimal, domain‑agnostic root** that makes such category errors impossible **by construction** and gives engineers and managers a clean, uniform handle for composition, boundaries and interfaces.

### A.1:2 - Problem

If FPF treats **system** as the universal root, two recurrent failure modes appear:

1. **Category Error** — physical affordances get projected onto abstract artifacts (ports on theories; kilogram‑mass of paradigms).
2. **Mereological Over‑reach** — part–whole calculus is applied to genuinely atomic entities (prime numbers, elementary charges), producing meaningless “sub‑parts.”

A robust kernel **separates identity from structure**: first say *what can be singled out*, then say *what has parts*.

### A.1:3 - Forces

| Force                         | Tension                                                                                                    |
| ----------------------------- | ---------------------------------------------------------------------------------------------------------- |
| **Universality vs Intuition** | Precision of a new root term (*Holon*) ↔ practitioner expectation of familiar words (*System*, *Theory*).  |
| **Purity vs Pragmatism**      | Clean formalism ↔ immediate usability for engineers, scientists, managers.                                 |
| **Structure vs Identity**     | Need to talk about atoms with zero parts ↔ need full mereology for composites.                             |

### A.1:4 - Solution — A three‑tier root (Entity ⊃ Holon ⊃ {System, Episteme})

FPF adopts a **three‑tier root ontology** refining Koestler’s “holon,” with crisp boundaries and safe composition. 

#### A.1:4.1 - `U.Entity` — Primitive of Distinction
Anything that can be individuated and referenced. **No structural assumptions.** Use when you need to name “a something” without committing to having parts.

> **Naming note (mint vs reuse).** `U.Entity` and `U.Holon` are minted kernel terms: they reuse familiar words but intentionally diverge from domain‑specific ontologies and DDD “Entity”, so we can reason cross‑domain without importing hidden assumptions.

#### A.1:4.2 - `U.Holon` — Unit of Composition
A `U.Entity` that is *simultaneously* **(a)** a whole composed of parts and **(b)** a part within a larger whole. Formally, `U.Holon ⊑ U.Entity`.
Well‑formedness constraints:

* **WF‑A1‑1 (Single boundary).** A holon has **exactly one** `U.Boundary` that separates it from its environment.
* **WF‑A1‑2 (Γ domain).** The universal aggregation operator **Γ** is defined **only** on sets of `U.Holon` (never on bare `U.Entity`).
* **WF‑A1‑3 (Γ scope).** A Γ‑application is scoped to a declared context and a single declared temporal scope (design **or** run); order/time are routed to Γ\_ctx / Γ\_time (B.1.4).

These constraints make composition rules uniform across domains and prevent Γ from being misapplied.

#### A.1:4.3 - Interface primitives: `U.Boundary` & `U.Interaction`
Every holon is defined by **how** it is separated and **what** crosses the separation.

* **`U.Boundary`** — physical or conceptual surface delimiting the holon’s scope.
* **`U.Interaction`** — any flow of matter, energy, or information that crosses a boundary.
  **Canonical boundary kinds (with twin archetypes):**

| Kind          | Permitted exchanges             | `U.System` archetype               | `U.Episteme` archetype                                        |
| ------------- | ------------------------------- | ---------------------------------- | ------------------------------------------------------------- |
| **Open**      | Matter, energy, information     | Microservice exposing a public API | Public wiki editable by anyone                                |
| **Closed**    | Energy, information (no matter) | Sealed cooling loop in a server    | Version‑locked theory accepting new evidence but fixed axioms |
| **Permeable** | User‑filtered subset            | Cell membrane regulating ions      | Legal code allowing specific amendment classes only           |

This pair (`Boundary`, `Interaction`) makes interfaces explicit, reviewable, and testable across domains.

#### A.1:4.4 - Inside/Outside decision procedure
To decide whether an entity **E** is *inside* a holon **H**, apply:

1. **Dependency test:** removing **E** breaks a core invariant of **H**.
2. **Interaction test:** **E** participates in causal loops wholly within **H**’s boundary.
3. **Emergence test:** **E** contributes to a novel collective property warranting **H** as a single unit.
   Fail all three → **E** is *outside*. This practical triage prevents “scope creep” and forces explicit modeling of environment vs interior.

> **Collections vs collectives.** A set/collection of holons is not itself an acting unit. If a grouping is expected to act, model it as a `U.System` holon with its own boundary and attach roles/methods/work to that system (see CC‑A1.6; details in A.2 and A.15).

#### A.1:4.5 - Archetypal sub‑holons
FPF fixes two **archetypal** specializations to ground cross‑domain universality:

| Subtype                    | Essence                                                | Home architheory |
| -------------------------- | ------------------------------------------------------ | ---------------- |
| **`U.System ⊑ U.Holon`**   | Physical, operational holon obeying conservation laws. | **Sys‑CAL**      |
| **`U.Episteme ⊑ U.Holon`** | Knowledge holon (axioms, evidence, argument graph).    | **KD‑CAL**       |

> **Agency rule.** Behavioural roles and executed methods/work attach to `U.System` holons only; `U.Episteme` is passive content. Any change to an episteme is performed by an external system acting across a boundary (cf. CC‑A1.5 and A.2/A.15).

*Naming guideline:* keep “**System**” and “**Episteme**” for practitioner comfort; reserve **Holon** for meta‑level discourse and formal signatures.

### A.1:5 - Archetypal Grounding (System / Episteme)

| Holonic slot | **`U.System` — Water‑pump**            | **`U.Episteme` — Scientific theory**            |
| ------------ | -------------------------------------- | ----------------------------------------------- |
| **Identity** | Pump #37 stamped on the name‑plate     | “Newtonian Gravitation”, 1726 edition           |
| **Boundary** | Cast‑iron casing; inlet/outlet flanges | Axiomatic scope and vocabulary                  |
| **Parts**    | Motor, impeller, seals, housing        | Axioms, definitions, theorems, datasets         |
| **Whole**    | Operable assembly that moves fluid     | Coherent body of knowledge predicting phenomena |

Showing the **same structural slots** filled by a machine and a theory demonstrates the **substrate‑independent universality** of `U.Holon`. This is the didactic “Tell–Show–Show” anchor required by the Style‑Guide for architectural patterns. 

### A.1:6 - Bias-Annotation — Boundary-first modelling risks

This kernel distinction is intentionally **boundary‑first**: it treats “where the boundary is” as a modelling decision that shapes everything downstream. That framing is powerful, but it can also smuggle bias if boundary choices are made implicitly or for political convenience.

| Lens | Typical bias risk | Mitigation in this pattern |
|---|---|---|
| **Gov** | Boundary decisions become “org charts”, not defensible model choices. | Record boundary rationale in the working model and require the **Inside/Outside test** (A.1:4.4) for contested cases. |
| **Arch** | Over‑modularisation: every interaction becomes a “system” with hard edges. | Prefer **permeable boundaries** when the phenomenon is gradient‑like; keep the `U.Entity`/`U.Holon` split minimal and push dynamics into Roles (A.2) and Work (A.15). |
| **Onto/Epist** | Category error: treating knowledge artifacts as physical actors (or vice‑versa). | Keep `U.Episteme` passive; model transformations as actions of a `U.System` in role, acting via explicit carriers (see A.10). |
| **Prag** | “Holon” becomes jargon that slows teams down. | Use `U.System` / `U.Episteme` in day‑to‑day models; reserve “holon” for kernel‑level discourse (see naming guidance in A.1:4.5 and CC‑A1.8). |
| **Didactic** | Readers infer semantics from overloaded labels or inconsistent headings. | Keep canonical titles and the `U.*` prefixes explicit; avoid informal deontic language in normative clauses (E.8). |

### A.1:7 - Conformance Checklist (normative)

| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------- |
| **CC‑A1.1** | Any modelled object that exhibits a part–whole structure **MUST** be typed as `U.Holon` or its subtype.                                                                        | Prevents applying Γ to atomic entities; makes aggregation well‑typed.                                                  |
| **CC‑A1.2** | Each `U.Holon` **MUST** reference exactly one `U.Boundary` and declare its boundary kind (*open / closed / permeable*).                                                        | Enables boundary inheritance and environmental Standards; aligns with the canonical boundary kinds introduced in A.1.  |
| **CC‑A1.3** | Domain architheories **MUST** explicitly subtype their root concept (`U.System`, `U.Episteme`, …) from `U.Holon`.                                                              | Ensures cross‑domain compatibility of aggregation and emergence patterns.                                              |
| **CC‑A1.4** | Inside/Outside decisions for any candidate part **SHALL** be justified by the three‑step test (Dependency → Interaction → Emergence) and recorded with the boundary reference. | Makes holon membership auditable and repeatable; uses A.1’s decision procedure.                                        |
| **CC‑A1.5** | Behavioural roles (**including** `TransformerRole`) **SHALL** attach only to `U.System` (the bearer), not to `U.Holon` in general and not to `U.Episteme`.                     | Preserves Strict Distinction and prevents category errors; episteme roles are classificatory only.                     |
| **CC‑A1.6** | Do **not** model acting groups as sets. If a grouping is expected to **act**, it **SHALL** be modelled as a **collective system** (with boundary, role, Method/Work).          | Distinguishes `MemberOf` (collection) from mereology; prepares for A.14 Portions/Phases.                               |
| **CC‑A1.7** | The universal aggregation operator **Γ** **SHALL** be applied **only** to sets of `U.Holon` within a single declared temporal scope (design **or** run) and context.           | Prevents “chimera” graphs; routes order/time to Γ\_ctx / Γ\_time (B.1.4).                                              |
| **CC‑A1.8** | Prose and diagrams **SHALL** follow the naming guideline: use **Holon** for meta‑level discourse; prefer **System / Episteme** in practitioner‑level statements.               | Reduces jargon friction; keeps signatures precise and text readable.                                                   |

> *Audit tip.* CC‑A1.5 is frequently violated when authors write “holon bearing TransformerRole”. Rewrite to “**system** bearing TransformerRole” or provide the explicit `U.RoleAssignment`. See A.2/A.15 for role mechanics.

### A.1:8 - Common Anti‑Patterns and How to Avoid Them — Manager’s quick checks

1. **“Ports on a theory.”** Treating a proof corpus as if it had physical connectors. *Fix:* model `U.Interaction` only across **boundaries**; for epistemes, interactions are **symbolic flows** via carriers and citations (see A.10), not power or mass.
2. **“Document edited itself.”** Assigning actions to an episteme. *Fix:* actions are executed by a **system bearing a role** (A.12/A.15); epistemes are transformed **via external transformers** acting on their **symbol carriers**.
3. **“Parts everywhere.”** Forcing a part–whole onto atomic entities (e.g., prime numbers). *Fix:* if no meaningful parts exist, stay at `U.Entity`; apply Γ only to `U.Holon`.
4. **“Scope ≡ section.”** Using “scope” as a text region rather than a modeled boundary. *Fix:* define a `U.Boundary` and state what crosses it (`U.Interaction`).

> **When in doubt:** first decide **what is a holon**, then state **its boundary**, then list **what crosses**. Roles and methods come *after* (see A.2 and A.15).

### A.1:9 - Consequences (informative)

| Benefits                                                                                                                                                         | Trade‑offs / Mitigations                                                                                                        |
| ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
| **Eliminates category errors** across physical and abstract realms by cleanly separating identity (Entity), structure (Holon), and behaviour (Role/Method/Work). | Introduces the unfamiliar term **Holon**; mitigated by Tell‑Show‑Show pedagogy and dual archetypal examples (System/Episteme).  |
| **Unifies aggregation**: a single algebra Γ composes pumps, proofs, genomes, and teams under one roof.                                                           | Requires refactoring legacy “System‑only” language; addressed by A.2/A.3 role calculus and the Γ‑family in B.1.                 |
| **Predictable extension point**: CAL/LOG/CHR architheories add constraints without touching the core types.                                                      | Imposes discipline on boundary declarations; mitigated by boundary kinds and the Inside/Outside test.                           |

### A.1:10 - Rationale — Cross‑domain corroboration (post‑2015, informative)

The separation **Entity → Holon → {System, Episteme}** is not only ontologically clean; it is **empirically validated across domains since 2015**:

* **Compositional open systems.** Category‑theoretic treatments show that *boundaried* components compose safely (decorated cospans, open systems). This mirrors Γ’s reliance on declared boundaries. *(Fong & Spivak, 2019; Baez & Courser, 2017)*
* **Microservices & bounded contexts.** Modern software architecture stresses strong service boundaries and local reasoning as the route to evolvability—our `U.Boundary` and Inside/Outside test encode the same discipline. *(Newman, 2021; Vernon, 2022)*
* **FAIR & provenance.** Data/knowledge communities require explicit distinction between **content** and **carrier**, and auditable provenance—precisely the System/Episteme + SCR split used in A.1/A.10. *(Wilkinson et al., 2016; Boeckhout et al., 2018)*
* **Digital Twin / Thread.** Engineering practice since late‑2010s emphasises the run↔design seam and boundary‑consistent aggregation of subsystems—formalised in our Γ‑family and boundary inheritance rules. *(Grieves & Vickers, 2017; NIST DT/Thread reports 2019‑2021)*
* **Layered control of CPS.** Standard‑based, multi‑rate architectures justify explicit holon boundaries and scale transitions—feeding directly into B.2 Meta‑Holon Transition. *(Matni et al., 2024)*

These streams converge on one point: **make boundaries and composition first‑class** and separate **what a thing is** from **what it is doing here‑and‑now**—the heart of A.1/A.2.

### A.1:11 - SoTA-Echoing (post‑2015, informative)

This solution echoes several modern (post‑2015) research and engineering streams. We **adopt** their boundary‑and‑composition insights, but **reject** any requirement to commit to a single formalism (per Notational Independence).

| Stream | Representative sources | Adopt / Adapt / Reject | What we take (and what we diverge from) |
|---|---|---|---|
| Compositional open systems | Baez & Courser (2017); Fong & Spivak (2019) | **Adapt** | Take the idea that composition should be explicit and typed; diverge by keeping the Core notation‑independent (no category‑theory prerequisite). |
| Software boundaries and bounded contexts | Newman (2021); Vernon (2022) | **Adopt** | Take boundary‑scoped meaning and ownership as the default; diverge by lifting “bounded context” to a kernel boundary concept rather than a software‑only practice. |
| FAIR / provenance for epistemic artifacts | Wilkinson et al. (2016); Boeckhout et al. (2018) | **Adopt** | Take provenance and carrier/content separation; diverge by modelling knowledge artifacts as `U.Episteme` (passive) rather than agents. |
| Digital twin / digital thread | Grieves & Vickers (2017); NIST DT/Thread (2019–2021) | **Adapt** | Take the run↔design seam; diverge by requiring a boundary kind at the holon level. |
| Systems/control criteria for emergence | Matni et al. (2024) | **Adopt** | Take emergence as a criterion for systemhood; diverge by requiring explicit boundary declarations even when “obvious”. |

### A.1:12 - Relations

* **Builds / Grounds:**

  * **A.2 Role Taxonomy** — A.1 provides the substantial characteristic (`Holon`), A.2 introduces the functional characteristic (`Role` and `U.RoleAssignment`). Together they prevent role/type explosion and keep agency contextual.
  * **A.7 Strict Distinction (Clarity Lattice)** — A.1 supplies the *slots* (Entity/Holon/System/Episteme); A.7 guards their separation in prose and models, stopping Object ≠ Description ≠ Carrier conflations.
  * **A.14 Advanced Mereology: Portions & Phases** — A.1’s holon substrate is the target of A.14’s edge discipline (`ComponentOf`, `ConstituentOf`, `PortionOf`, `PhaseOf`); only mereological subtypes build holarchies.

* **Interacts with the Γ‑family (B‑cluster):**

  * **B.1 Universal Algebra of Aggregation** — Γ is defined **on holons** and respects CC‑A1.\*; Γ\_ctx/Γ\_time carry order and temporal composition, Γ\_work handles resource ledgers.
  * **B.2 Meta‑Holon Transition (MHT)** — uses A.1’s boundary and Inside/Outside rules to decide when aggregation yields a **new** whole with novel properties.
  * **B.3 Trust & Assurance Calculus** — evidence attaches to carriers (SCR/RSCR) of epistemes; assurance levels depend on A.1/A.10 alignment.
  * **B.4 Canonical Evolution Loop** — operationalises the **design↔run** seam at holon boundaries; observation itself is an external transformation across a boundary.

* **Specialised by architheories:** `U.System` (Sys‑CAL) and `U.Episteme` (KD‑CAL) are archetypal sub‑holons that supply domain‑specific invariants while inheriting A.1’s boundary and aggregation duties. 

*Without the holon, parts drift; without the role, purpose evaporates.* (Carry this epigraph with A.1 to cue the A.2 hand‑off.)

### A.1:End

## A.1.1 - `U.BoundedContext`: The Semantic Frame

> **Type:** Architectural (A)  
> **Status:** Stable  
> **Normativity:** Normative

*Make meaning local; make translation explicit.*

### A.1.1:1 - Problem Frame

Large systems of thought (and large engineered systems) break down when meaning is treated as globally uniform.
The same label (e.g., “role”, “service”, “ticket”, “evidence”) routinely carries incompatible senses across teams, disciplines, standards editions, and historical eras.

FPF needs a first-class mechanism that answers a simple question with precision:
**“In which semantic frame does this term, rule, or role-claim hold?”**

The `U.BoundedContext` is that mechanism. It makes “it depends” explicit and governable by naming *what it depends on*.

### A.1.1:2 - Problem

Absent an explicit, first-class semantic frame:

1. **Ambiguity becomes structural debt.** Integrations silently overwrite meanings (“process” becomes “procedure”; “role” becomes “permission”), and the resulting model cannot be audited.
2. **Pluralism looks like contradiction.** Two valid perspectives appear mutually exclusive because the frame of reference is implicit (e.g., Pluto as `PlanetRole` vs `DwarfPlanetRole`).
3. **Roles lose semantic footing.** A `U.Role` without a declared frame degenerates into a global label, violating the kernel’s insistence that roles are contextual masks (A.2, A.2.1).
4. **Local rules leak globally.** Team- or theory-specific invariants are mistaken for universal laws, producing incoherent cross-domain reasoning.

### A.1.1:3 - Forces

| Force | Tension |
| :--- | :--- |
| **Local coherence** | A context must be internally unambiguous ↔ real work crosses boundaries and needs translation. |
| **Pluralism** | Multiple valid frames must coexist ↔ readers demand apparent “one truth”. |
| **Governance cost** | Explicit boundaries and rules improve reliability ↔ too many contexts create overhead and fragmentation. |
| **Evolvability** | Contexts must change over time ↔ change must remain traceable and non-destructive to prior meaning. |
| **Familiarity** | Practitioners use domain-native vocabulary ↔ the kernel must stay universal and type-stable. |
| **Domain-family convenience** | People want “the domain” as a handle ↔ FPF requires specific, named semantic frames. |

#### A.1.1:3.1 - Prophylactic clarification — Domain family vs `U.BoundedContext`

To prevent a common category error, **Domain (as used colloquially)** and **`U.BoundedContext`** are **not synonyms** in FPF, and “Domain” is not a kernel type.
Per **E.10.D1 (D.CTX)**, **Domain is an informative family label** grouping multiple contexts; there is no “domain context”.

| Characteristic | **Domain family (informative)** (e.g., Healthcare, Physics, Workflow) | **`U.BoundedContext`** (e.g., `Hospital.OR_2025`, `Theory:QuantumMechanics`, `BPMN_2_0`) |
| :--- | :--- | :--- |
| **Nature** | An external field of practice/knowledge; a catalog handle. | An internal FPF holon: a named semantic frame with local vocabulary and local invariants. |
| **Role in FPF** | Groups contexts for survey, coverage, and stewardship discussions. | Localizes meaning and rules; provides a semantic firewall where words and obligations are coherent. |
| **Relationship** | One family hosts many legitimate perspectives/editions. | One context hosts one such perspective with explicit `Glossary`, `Invariants`, `Roles`, and optional `Bridges`. |

**Well-formedness constraint (didactic):** In any `U.RoleAssignment`, `context` is total and points to **exactly one** `U.BoundedContext` (cardinality **1..1**).
*Think “specific room” (e.g., `Hospital.OR_2025`), not “the whole building” (e.g., “Healthcare”).*

**Manager’s one-liner:** A **Domain family** is the *territory label*; a **Bounded Context** is a *purpose-made map* of one perspective on that territory.

### A.1.1:4 - Solution

FPF elevates **semantic framing** to a kernel primitive by introducing `U.BoundedContext` as a first-class holon of meaning.
Inspired by Domain-Driven Design (DDD) but generalized beyond software, a bounded context is not a mere namespace: it is **a governable model locale** with explicit vocabulary, rules, and role taxonomy.

#### A.1.1:4.1 - Term & Definition

* **Term:** `U.BoundedContext`
* **Definition:** A **`U.BoundedContext`** is a `U.Holon` that serves as an explicit **semantic frame of reference**. It declares a boundary within which a specific vocabulary, role taxonomy, and invariant set are coherent and authoritative. It is FPF’s kernel mechanism for localizing meaning and managing complexity by partitioning a larger conceptual space into smaller, coherent, independently governable **semantic locales** (Contexts).

**Mint vs reuse** (informative): The label "Bounded Context" is reused from DDD; `U.BoundedContext` is the FPF-defined kernel type (generalized beyond software). Cross-context sameness is never inferred from spelling; cross-context alignment is represented only via explicit `Bridge` artifacts (F.9; E.10.U9; see CC-A1.1.5).

#### A.1.1:4.2 - Core components (normative shape)

A `U.BoundedContext` is a composite holon whose *parts* constitute the context’s local “constitution”:

* **`Glossary` (Local Lexicon):** A set of `U.Lexeme` entries (Lang-CHR) defining the local vocabulary and its intended senses. This is where a context can state: “Inside here, `ticket` denotes `U.WorkItem`, not `U.TravelPermit`.”
* **`Invariants` (Local Rules):** A set of `U.ConstraintRule`s (Norm-CAL) that must hold for artifacts and processes operating in this context. These rules define the context’s local “physics”.
  * *Example (role compatibility):* “Within this context, a `holder` cannot simultaneously play `AuditorRole` and `DeveloperRole`.”
  * *Example (state transition):* “A `U.WorkItem` can transition from `InProgress` to `InReview`, never directly to `Done`.”
* **`Roles` (Local Taxonomy):** A partial order of `U.Role`s that are defined and valid only within this context. It specifies the “masks” available on this stage (A.2).
* **`Bridges` (Optional alignments):** A set of explicit cross-context relations (`U.Alignment`, formalized in F.9 / E.10.U9) describing how meaning translates when information crosses context boundaries, including loss/fit notes.
  * *Example (alignment):* “`AgileDevelopment:UserStory` is congruent (CL=1) to `FormalEngineering:Requirement` under the stated loss policy.”

#### A.1.1:4.3 - Context interactions with other kernel objects (normative)

* **As a `U.Holon`:** A `U.BoundedContext` has a defined `U.Boundary` and internal parts (`Glossary`, `Invariants`, …). However, **contexts do not form holarchies with each other**: per E.10.D1 (D.CTX), contexts have no is‑a or containment relations; cross-context relationships are expressed only via explicit `Bridges`.
* **As the semantic frame for `U.RoleAssignment`:** The `context` field of `U.RoleAssignment` identifies the unique semantic frame in which the holder-role assignment is interpreted (A.2.1).
* **As the scope carrier for rules and objectives:** `U.Objective`s and `U.ConstraintRule`s are typically authored and evaluated relative to a specific context’s invariants.
* **As a change target:** Context evolution (new invariants, revised glosses, deprecated roles) is modeled as a `U.Transformer` acting on the `U.BoundedContext` holon itself. Where time is merely stance (`design`/`run`), treat it as a TimeScope tag, not a new context (C‑7; D.CTX).

> *If meaning is local by design, then translation must be explicit by design.*

**Admissibility constraints (concept-level; non-deontic).**

* **BC‑1 (Holon nature).**  A `U.BoundedContext` is a `U.Holon` and declares a `U.Boundary`.
* **BC‑2 (Flat context map).** No `U.BoundedContext` is modeled as inheriting from, containing, or being contained by another `U.BoundedContext`; cross-context relations are represented only via explicit `Bridges` (E.10.D1 / E.10.U9).
* **BC‑3 (Role localization).** Every `U.Role` is defined in the `Roles` taxonomy of at least one `U.BoundedContext`; a "global role" is not a valid kernel object.
* **BC‑4 (Invariant scope).** Any invariant authored in a Context applies only to holons and processes operating within that Context; cross-context reuse is mediated by Bridges and re‑stated locally.
* **BC‑5 (Bridge explicitness).** Any interaction or semantic alignment between two Contexts is represented by an explicit `Bridge` artifact.
* **BC-6 (RoleAssignment context field).** A `U.RoleAssignment` references exactly one `U.BoundedContext` in its `context` field (cardinality 1..1).
* **BC‑7 (Domain is metadata).** "Domain" denotes only an informative family label grouping multiple contexts; it is not a kernel type and does not substitute for `U.BoundedContext` (E.10.D1).

### A.1.1:5 - Archetypal Grounding

The concept of a `U.BoundedContext` is universal and applies to both physical/operational domains and purely abstract/epistemic ones. Understanding these two archetypes clarifies its role as a fundamental FPF primitive.

| Archetype | Stewarding community | `U.BoundedContext` Example | Core Components Illustrated |
| :--- | :--- | :--- | :--- |
| **`U.System` Archetype** | A modern software engineering team | **`AgileProject:Phoenix`** | **`Glossary`**: Defines "Story Point," "Sprint," "Velocity." <br> **`Invariants`**: "Daily stand-up must not exceed 15 minutes." "A Story cannot move to 'Done' without a linked Test Case." <br> **`Roles`**: `ProductOwnerRole`, `ScrumMasterRole`, `DeveloperRole`. <br> **`Bridges`**: Maps `Velocity` metric to the `FinanceDept` context's `CostCenter:BudgetBurnRate`. |
| **`U.Episteme` Archetype** | A scientific community | **`Theory:SpecialRelativity`** | **`Glossary`**: Defines "Inertial Frame," "Lorentz Transformation," "Proper Time." <br> **`Invariants`**: "The speed of light in a vacuum is constant for all observers." "The laws of physics are the same in all inertial frames." <br> **`Roles`**: `Postulate#AxiomaticCoreRole`, `Experiment#EvidenceRole`. <br> **`Bridges`**: Maps its concept of "Spacetime" to the `GeneralRelativity` context's more complex concept of "Curved Spacetime." |

**Key takeaway from grounding:**
This illustrates that a `U.BoundedContext` is not an abstract container but a **holon with tangible content**. For the engineering team, it's their project's "operating system." For the scientific theory, it's the "intellectual constitution." In both cases, the context defines what is true, what is possible, and what words mean *locally*.

### A.1.1:6 - Bias-Annotation

This pattern is intentionally universal, but it can be misread through narrower lenses:

* **Software-centrism bias:** Readers may assume “bounded context” only applies to microservices/teams. *Mitigation:* the Episteme archetype is first-class; contexts apply equally to theories, standards, and scientific practices.
* **Boundary reification bias:** Authors may treat boundaries as “natural facts” rather than modelling choices. *Mitigation:* boundaries are declared for governance and clarity, and cross-context relations are handled via Bridges with explicit loss/fit.
* **English-label bias:** Examples often use English surface terms, which can hide multilingual drift. *Mitigation:* language/edition discipline in D.CTX governs when to split/merge contexts; multilingual labels are metadata when semantics are truly bound.

### A.1.1:7 - Conformance Checklist

To ensure `U.BoundedContext` is used consistently and rigorously, the following normative checks apply.

| ID | Requirement (Normative Predicate) | Purpose / Rationale |
| :--- | :--- | :--- |
| **CC-A1.1.1 (Holon Nature)** | A `U.BoundedContext` **MUST** be modeled as a `U.Holon` with a defined `U.Boundary`. | Reinforces that contexts are well-defined entities, not vague groupings. Enables reasoning about contexts themselves as systems. |
| **CC-A1.1.2 (Flat Context Map)** | A `U.BoundedContext` **MUST NOT** be modeled as inheriting from, containing, or being contained by another `U.BoundedContext`. Cross-context relations **MUST** be expressed only via explicit `Bridges` (E.10.D1 / E.10.U9). | Prevents semantic leakage and hidden globalism; keeps cross-context translation auditable and loss-aware. |
| **CC-A1.1.3 (Role Localization)** | Every `U.Role` **MUST** be defined within the `Roles` taxonomy of at least one `U.BoundedContext`. A "global role" is forbidden. | Ensures roles are never context-free; meaning remains local and checkable. |
| **CC-A1.1.4 (Invariant Scope)** | An invariant defined within a context **MUST** only apply to holons and processes operating *within* that context. | Prevents local rules from leaking into global reasoning; preserves modularity. |
| **CC-A1.1.5 (Bridge Explicitness)** | Any interaction or alignment between two `U.BoundedContext`s **MUST** be modeled as an explicit `Bridge` artifact. | Forbids implicit cross-context equivalences; makes dependencies visible and auditable. |
| **CC-A1.1.6 (RoleAssignment Context Binding)** | Every `U.RoleAssignment` **MUST** reference exactly one `U.BoundedContext` in its `context` field (cardinality 1..1). | Guarantees that each assignment is interpreted in one authoritative frame of meaning. |
| **CC-A1.1.7 (Domain family is informative)** | “Domain context” **MUST NOT** appear in normative prose; Domain labels **MAY** appear only as informative family metadata that groups multiple contexts (E.10.D1). | Prevents the domain/context conflation that breaks locality and auditability. |

### A.1.1:8 - Common Anti-Patterns and How to Avoid Them

These failure modes recur when applying `U.BoundedContext` in real programs and knowledge work.

| Anti-pattern | Symptom | Why it fails (force violated) | How to avoid / repair |
| :--- | :--- | :--- | :--- |
| **Domain-as-Context** | “Healthcare” or “Physics” is used where a specific context is required. | Violates Domain-family convenience vs precision; meaning stays ambiguous. | Use a specific context id (edition- and source-scoped), and keep the domain label as informative family metadata only. |
| **Implicit equivalence across contexts** | The same string in two contexts is treated as “obviously the same”. | Violates local coherence; creates silent semantic overwrites. | Publish an explicit Bridge with relation kind and loss/fit note (F.9 / E.10.U9). |
| **Context hierarchy / nesting** | Authors model “sub-contexts” as containment or is‑a between contexts. | Violates the flat context map discipline; leaks rules by inheritance. | Remove context-to-context containment; express relationships via Bridges only (E.10.D1). |
| **Time-as-Context** | “Design context” and “Runtime context” are created as separate contexts. | Violates evolvability and clarity; multiplies frames incorrectly. | Use TimeScope tags (`design`/`run`) on artifacts and sources; keep the semantic frame fixed (C‑7; D.CTX). |
| **Glossary-only context** | A context is defined by vocabulary but has no invariants or role taxonomy. | Violates governance intent; “local truth” remains implicit. | Add at least one invariant and a minimal local role taxonomy, even if initially coarse. |

### A.1.1:9 - Consequences

| Benefits | Trade-offs / Mitigations |
| :--- | :--- |
| **Enables True Modularity:** By encapsulating models, FPF can support large, complex systems where different teams can work on their own bounded contexts in parallel with minimal interference. | **Modeling Overhead:** Requires architects to explicitly think about and define the boundaries of their models, which can feel like extra work initially. *Mitigation:* This upfront effort is a strategic investment that prevents the much higher cost of integration chaos and semantic ambiguity later in the project. |
| **Resolves Ambiguity and Paradox:** Provides a formal mechanism to manage synonyms, homonyms, and conflicting models (like the Pluto example). It transforms "it depends" into a precise, queryable structure. | **Bridge Maintenance:** As contexts evolve, the bridges between them must be maintained. *Mitigation:* FPF tooling should support "link integrity" checks to automatically flag broken or outdated bridges. |
| **Makes Rules Explicit:** The `Invariants` component of a context makes the local rules and invariants for a project or theory explicit, documented, and auditable. | - |
| **Foundation for Scalable Autonomy:** In multi-agent systems, each agent can operate within its own bounded context, communicating with others through well-defined bridges. This is a prerequisite for building robust, decentralized systems. | - |

### A.1.1:10 - Rationale

**Lineage and fit with Domain‑Driven Design (DDD).**  
FPF generalizes the proven DDD idea of a **Bounded Context** from software into a universal modeling primitive:

| DDD concept | FPF counterpart | Generalization in FPF |
| :--- | :--- | :--- |
| Bounded Context | **U.BoundedContext** (a holon) | Used for systems **and** knowledge; first‑class object with explicit Glossary, Invariants, local Roles, Bridges. |
| Ubiquitous Language | **Glossary** of the context | The shared vocabulary is an explicit component, not just narrative. |
| Context Map | **Bridges/Alignment** between contexts | Cross‑context relations are modeled explicitly rather than assumed globally. |

**Why this matters here.**  
`U.BoundedContext` gives `U.RoleAssignment` (A.2.1) its footing: role meanings are **local by design**, conflicts are checked **inside** the same context, and differences **across** contexts are handled by **explicit Bridges** instead of “global truth.”

The introduction of `U.BoundedContext` as a first-class holon is a direct implementation of several core FPF principles and is strongly supported by contemporary practice.

*   **Philosophical Grounding:** The idea that meaning is always local and context-dependent is a cornerstone of late 20th-century philosophy of language (e.g., Wittgenstein's "language-games"). FPF operationalizes this insight.
*   **Domain-Driven Design (DDD):** The concept is a direct borrowing and generalization from Eric Evans' seminal work on DDD, where the Bounded Context is the central strategic pattern for managing complexity in large-scale software. Its success over the past two decades in the software industry provides powerful empirical validation for its utility. FPF elevates it from a software design pattern to a universal ontological primitive.
*   **Architectural Necessity:** For FPF to fulfill its promise of being an "operating system for thought," it needs a mechanism analogous to an OS's "process separation." A `U.BoundedContext` is precisely that: a protected "memory space" for a model, preventing different models from corrupting each other.
*   **Enabler for Key Patterns:** The `Contextual Role Assignment` pattern (A.2.1) would be incoherent without a formal definition of "Context." This pattern provides that necessary foundation, making the entire role-based architecture sound.

In essence, `U.BoundedContext` is the architectural pattern that allows FPF to be both **universal** in its core principles and **specific** and **pluralistic** in its applications. It is the mechanism that tames complexity and makes large-scale, multi-paradigm modeling possible.

### A.1.1:11 - SoTA-Echoing (post-2015 practice alignment)

The `U.BoundedContext` concept aligns strongly with contemporary (post‑2015) practice in software architecture, socio-technical design, and knowledge/provenance disciplines. Where FPF differs, it does so to preserve kernel universality, explicit loss-aware translation, and auditability.

| Claim (A.1.1 need) | SoTA practice (post‑2015) | Primary source (post‑2015) | Alignment with A.1.1 | Adoption status |
| :--- | :--- | :--- | :--- | :--- |
| Meaning boundaries must be explicit to scale development. | Modern microservice architecture stresses clear service boundaries and local reasoning to keep systems evolvable. | Newman (2021), *Building Microservices* (2nd ed.). | A.1.1 adopts the boundary-first stance but generalizes it from “service boundaries” to a universal semantic holon with explicit local invariants and roles. | **Adopt/Adapt.** Adopt boundary discipline; adapt by making the semantic frame a first-class kernel object, not only a team convention. |
| Organizational boundaries and cognitive load shape semantic boundaries. | Socio-technical architecture practice encourages team-aligned boundaries and explicit interaction modes to prevent cognitive overload. | Skelton & Pais (2019), *Team Topologies*. | A.1.1 aligns by treating a context as governable by a stewarding community, but requires explicit Bridges when knowledge crosses boundaries (rather than relying on tacit coordination). | **Adopt.** Directly supports local autonomy; tighten with explicit cross-context translation artifacts. |
| Cross-domain data integration needs explicit contracts, not implicit “one truth”. | Data Mesh emphasizes domain-oriented data products and explicit interoperability contracts across domains. | Dehghani (2022), *Data Mesh* (book form of the 2019–2021 program). | A.1.1 matches the “data product boundary” move, but insists that interoperability is expressed as explicit Bridges with loss/fit notes, preserving pluralism instead of collapsing it. | **Adapt.** Adopt the decentralization intuition; adapt by requiring explicit semantic alignment artifacts rather than assuming shared enterprise semantics. |
| Knowledge and artifacts must carry machine-actionable semantics and provenance. | FAIR and modern research-object packaging push for explicit metadata, provenance, and reuse conditions. | Wilkinson et al. (2016), FAIR Principles; RO‑Crate community specs (2019→). | A.1.1 supports this by making local meaning explicit (Glossary + Invariants) and making cross-context translation explicit (Bridges), enabling auditable reuse without pretending to globalize semantics. | **Adopt/Adapt.** Adopt provenance and reuse intent; adapt by separating semantic frame (Context) from carriers and by making loss explicit on crossings. |

### A.1.1:12 - Relations

*   **Constitutes:** The foundational "semantic space" for patterns like `A.2 Role Taxonomy` and `A.13 The Agential Role`.
*   **Builds on:** `A.1 Holonic Foundation`, as a `U.BoundedContext` is itself a `U.Holon`.
*   **Constrained by:** `E.10.D1 D.CTX`, which fixes the lexical discipline for “Context”, forbids context hierarchies, and makes Domain family informative.
*   **Interacts with:**
    *   `Norm-CAL`: A context's `Invariants` are typically expressed as `U.ConstraintRule`s.
    *   `Lang-CHR`: A context's `Glossary` is a collection of `U.Lexeme`s.
    *   `Decsn-CAL`: Decisions and objectives are often scoped to a specific context.
    *   `F.9 Alignment & Bridge`: the canonical locus of cross-context relations and loss policies.

### A.1.1:End


## A.2 - Role Taxonomy
> **Type:** Architectural (A)
> **Status:** Stable
> **Normativity:** Normative

*A holon’s essence tells us **what it is**; its roles tell us **what it is being, here and now**.*

### A.2:1 - Problem frame

Pattern A.1 established the **substantial** characteristic of the core (`Entity → Holon → {System, Episteme, …}`), cleanly separating identity from structure and aggregation. The present pattern introduces the **functional** characteristic: how a holon participates in purposes **within a bounded context** and for some interval. This extends the early sketch of A.2 and tightens its alignment with A.7 (Strict Distinction): roles are *not* parts and *not* behaviours; they are contextual **masks** that a holon wears while behaviours are handled by **Method**/**Work**. 

### A.2:2 - Problem

Without an explicit role calculus:

1. **Type explosion & conflation.** Each new purpose breeds a new “subtype” (`PumpAsCoolingLoop`, `PumpAsFuelLoop`, …), violating parsimony and fusing substance with function.
2. **Agency opacity.** It becomes unclear whether *any* system may act as a transformer/agent, or only pre-declared special kinds.
3. **Epistemic blindness.** Knowledge artefacts (papers, proofs) cannot be given roles, blocking modelling of citation, evidence, or design-time justification.

### A.2:3 - Forces

| Force                                | Tension                                                              |   |
| ------------------------------------ | -------------------------------------------------------------------- | - |
| **Identity vs Function**             | A holon’s make‑up ↔ its transient, contextual purpose.               |   |
| **Static vs Dynamic classification** | Fixed type lattice ↔ late‑binding of new roles.                      |   |
| **Universality vs Familiarity**      | One mechanism for pumps **and** papers ↔ domain‑specific role names. |   |
| **Simplicity vs Expressiveness**     | Minimal primitives ↔ multi‑role, multi‑holder scenarios.             |   |

### A.2:4 - Solution

We elevate **Role** to a first‑class semantic construct: a context‑bound *mask* (capability/obligation schema) worn by a holon. **Behaviour** and **resource deltas** live in **Method**/**Work**, not in the role itself.

#### A.2:4.1 - S‑level definitions (normative)

* **`U.Role`** — a **context-bound** capability/obligation schema that a holon **may bear (play)** for a time interval. A role has **no parts** and **no resource deltas** of its own. *(A7 guard)*
* **`U.RoleAssignment`** — a first-class assignment record recording that a holon **bears (plays)** a role **in** a bounded context over an optional **Window**. Keep the signature aligned with **A.2.1 Role Assignment Standard**; governance metadata (authority/justification/provenance) is captured via `U.RoleAssigning` and the evidence graph (A.10).

```
U.RoleAssignment {
  holder        : U.Holon,
  role          : U.Role,
  context       : U.BoundedContext,
  window? : U.Window
  justification?: U.Episteme,  // why (standard, SOP, evidence)
  provenance?   : U.Method     // how assignment/verification was done
}
```

Short form (readable): `Holder#Role:Context@Window`.

> **Why a first-class assignment record?** It keeps identity (holon), function (role), context (semantics), and time (run-window) separate yet linked, preventing the substance/function conflation identified above. The early `playsRoleOf(Holon, Role, span)` relation in the draft is subsumed by `U.RoleAssignment` and extended with **Context** (and optional governance fields).

#### A.2:4.2 - Temporal & behavioural alignment

* **MethodDescription** persists as Episteme. A Role **binds** to Method (design‑time), and Work **performs** Method under that Role (run‑time). This preserves the *role ≠ behaviour* split and the *design ↔ run* duality.
* Only **Work** carries resource deltas (feeds Γ\_work); a Role never does.

#### A.2:4.3 - Admissibility constraints (concept-level; non-deontic).

1. **Locality.** `role ∈ Roles(context)`. Outside its context, a role’s meaning is undefined.
2. **Non‑mereological.** No Role (nor Method/MethodDescription) may appear in any `partOf` chain; holarchies are for substantial holons only.
3. **Multiplicity.** A holder may **bear** multiple roles concurrently; a role may be **borne** by many holders—subject to each context’s compatibility rules.
4. **Time anchoring.** `timespan` (if present) is non-empty and finite for run-time claims; design-time assignments are timeless but versioned via `MethodDescription` identity.
5. **Behavioural coherence.** For any `U.Work` window, the performer plays the Role that binds the executed Method. *(No hidden role swaps.)*

#### A.2:4.4 - Taxonomic frame (within a context)

Within each `U.BoundedContext`, role names are organised as a **partial order** (refinements) plus an **incompatibility** relation (mutually exclusive roles). Typical **substrate‑neutral** anchors:

| Kernel Role       | Intent                                | System archetype              | Episteme archetype                       |   |
| ----------------- | ------------------------------------- | ----------------------------- | ---------------------------------------- | - |
| `TransformerRole` | Changes other holons via Method/Work. | Robot arm assembling casings. | Prover constructing a new lemma.         |   |
| `ObserverRole`    | Collects evidence / metrics.          | Sensor array on a test‑rig.   | Reviewer annotating an article.          |   |
| `SupervisorRole`  | Governs subordinate holons.           | PLC orchestrating a line.     | Meta‑analysis curator combining studies. |   |

> Domains refine these anchors: e.g., `CoolingCirculatorRole`, `CitationSourceRole`, `LemmaRole`.

### A.2:5 - Archetypal Grounding (Tell–Show–Show: System / Episteme)

**Tell.** A single holon can be the *same bearer* across time while taking on different, context‑bound roles. A role is a *mask* (capability/obligation schema) that explains *what it is being* in a given `U.BoundedContext`; behavioural facts and resource deltas remain in `U.Method` / `U.Work`.

**Show.**

**System case — Cooling loop**
`PumpUnit#3#HydraulicPump:Plant‑A`
`HydraulicPump ↦binds↦ ChannelFluid` (design)
`run‑2025‑08‑08 isExecutionOf centrifugal_pump_curve.ld` and `performedBy PumpUnit#3` (run)
*(All behavioural/resource facts live in Work; the Role is the mask.)*

**Episteme case — Standard in design**
`RFC‑9110.pdf#ProtocolStandard:WorldWideWeb` justifies `MethodDescription` selection; the **system** bearing `TransformerRole` is the design service that executed the selection work. The episteme did **not** act.

**Collective vs set (safety pitfall)**
A **set** `{Alice, Bob, 3.14}` has no behaviour; a **team** is a **system** with boundary, coordination **Method**, and supervision **Work**; only the latter can bear agentic roles.

### A.2:6 - Bias-Annotation

Lenses tested: **Arch**, **Onto/Epist**, **Prag**, **Did**. Scope: **Universal** (A‑cluster).

* **Architecture bias (Arch):** treating roles as structural parts can smuggle function into mereology and break holarchies.

* *Mitigation:* keep `partOf` chains role‑free; roles are not constituents (see CC‑A2.1).
  +* **Onto/Epist bias (Onto/Epist):** anthropomorphising epistemes collapses evidence into agency.
* *Mitigation:* epistemes can justify/authorize; only systems perform methods and work (CC‑A2.2).
  +* **Pragmatic bias (Prag):** over‑contextualising can fragment reuse and create naming drift.
* *Mitigation:* require explicit `:Context` binding and explicit bridges instead of silent equivalence (CC‑A2.4).
  +* **Didactic bias (Did):** metaphors (“mask”) may be misread as informal.
* *Mitigation:* bind obligations to CC items; avoid imperative prose outside CC.

### A.2:7 - Authoring guidance (for engineers and leads)

* **Name roles for intent, not mechanics.** Prefer `CoolingCirculatorRole` over `ChannelFluidWithCentrifugalProfile`.
* **Pin the context early.** If two teams disagree, split contexts and (optionally) define an alignment bridge; do not over‑generalise the role.
* **Document the enactment chain.** For any operational claim, be ready to point to: `RoleAssigning → Method ↔ MethodDescription → Work`. (Readers’ dictionary: *BPMN workflow → MethodDescription; operation/job → Work.*)

### A.2:9 - Common Anti-Patterns and How to Avoid Them

1. **“Transformer as system subtype.”**
   ✗ *“`U.TransformerSystem` builds pumps.”*
   ✓ *“`RobotArm R‑45#Transformer:Plant‑A` executed Work W.”* (Role is a mask; behaviour is Method/Work.)

2. **“Role as part.”**
   ✗ *“The pump’s role is one of its components.”*
   ✓ Roles are **never** parts; components are substantial. Keep all `partOf` chains role‑free.

3. **“Episteme acts by itself.”**
   ✗ *“The PDF enforced the SOP.”*
   ✓ An **episteme** can hold roles like `ProtocolStandard` **in context**, but only a **system** performs the Method/Work that uses it.

4. **“Context leakage.”**
   ✗ *“Pluto is Planet and DwarfPlanet.”* (in one tacit space)
   ✓ *“`Pluto#Planet:Early20thCenturyAstronomy`; `Pluto#DwarfPlanet:IAU_2006_Definition`.”* No contradiction—different bounded contexts. (Illustrative of `U.RoleAssignment` semantics carried forward from the A.2.1.)


### A.2:10 - Consequences

| Benefit                     | Why it matters                                                                                                       | Trade‑off / Mitigation                                                                       |
| --------------------------- | -------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------- |
| **Category‑error immunity** | Clear firewall between **identity** (holarchies) and **function** (roles) prevents mixing “parts” with “masks”.      | Slight modelling overhead; templates provide checklists (A.7, A.14).                         |
| **Operational clarity**     | Who does what, when, and under which mask becomes audit‑ready (`performedBy ⊆ playsRoleOf`).                         | Requires spans on Role assignments; mitigated by default “open‑ended” spans in drafts.          |
| **Epistemic hygiene**       | Knowledge holons contribute as **evidence** or **constraints**, never as doers.                                      | Authors must rewrite anthropomorphic prose; canonical rewrites help.                         |
| **Cross-context pluralism** | Same bearer can hold different roles across contexts without contradiction; differences are explicit in the assignment. | Requires declaring the **bounded context**; E.10 eases the ceremony with registers/aliases.  |
| **Γ‑coherence**             | Order/time/aggregation stay in Γ‑operators, not overloaded into “role" edges.                                        | Authors learn when to call Γ\_ctx/Γ\_time; the Part B on‑ramp is short.                      |

### A.2:11 - Rationale (post‑2015 cross‑domain corroboration)

*Why insist on roles as contextual masks and externalised transformers?*

1. **Constructor Theory (2015–2022).** Post‑2015 work by Deutsch & Marletto re‑centres physics on **possible tasks and constructors** rather than objects, mirroring FPF’s **TransformerRole**: behaviour is attached to “who can realise a task,” not to substance per se. Our separation of **SubstantialHolon** vs **Role** and the insistence on **external** transformers directly echo this shift. *(Conceptual alignment noted in A.2 Solution and A.12 intent.)* 
2. **Layered Control Architectures (Matni–Ames–Doyle, 2024).** The modern control stack cleanly **externalises** regulators and planners relative to plants. FPF’s obligatory “system bearing TransformerRole” (A.7, A.12) is isomorphic to that separation, keeping supervision and actuation **outside** the controlled holon. 
3. **Active‑Inference / Agency spectrum (2017–2023).** Contemporary models treat agency as **graded** and **contextual** (percept‑act loops tuned by free‑energy bounds). A.13 adopts exactly this: **AgentialRole** is a role worn by a holon, with graded measurements via **Agency‑CHR**, not a static type.
4. **Basal Cognition & multi‑scale organisation (2019–2024).** Fields & Levin argue for **cross‑scale** control and information flows; FPF encodes this via Γ‑flavours and the **Meta‑Holon Transition** triggers, ensuring Role assignments compose across scales without collapsing identity into function.
5. **Knowledge ecosystems & safety cases (2018–2025).** Modern assurance relies on **traceable evidence** and conservative integration (no “truth averaging”): our A.10 anchors (SCR/RSCR) and Γ\_epist’s **weakest‑link** fold implement that discipline and forbid self‑evidence. 

> Summing up: post‑2015 science and engineering converge on **roles as contextual capabilities**, **externalised control**, and **traceable evidence**. A.2 codifies these insights in a substrate‑neutral way, keeping the Core small yet powerful.

### A.2:12 - SoTA-Echoing (post‑2015 alignment, informative)

| Claim (A.2 need) | SoTA practice (post‑2015) | Primary source (post‑2015) | Alignment with A.2 | Adoption status |
| --- | --- | --- | --- | --- |
| Roles are context‑dependent, anti‑rigid descriptors rather than structural parts. | Conceptual modeling distinguishes substantial types from role types; roles depend on context/relational situations. | Guizzardi (2019), *Ontological Foundations for Conceptual Modeling*; recent OntoUML/UFO literature. | Maps to `U.Role` as context‑bound schema; keeps `partOf` free of roles. | **Adopt.** |
| Meaning boundaries must be explicit; reuse across boundaries must be declared, not assumed. | Modern DDD and socio‑technical architecture emphasise explicit bounded contexts and explicit translation/alignment. | Vernon (2016), *Domain‑Driven Design Distilled*; Newman (2021), *Building Microservices*. | Matches `role ∈ Roles(context)` and CC‑A2.4 context binding + explicit bridge discipline. | **Adopt/Adapt.** Adopt boundaries; adapt reuse via FPF Bridges + CL. |
| Agency should not be attributed to artifacts; treat evidence/provenance as first‑class. | Safety/assurance and governance treat documents as evidence and constraints; provenance is required for claims. | ISO 26262:2018; NIST SP 800‑53 Rev. 5 (2020). | Supports “episteme as justification” and CC‑A2.2/CC‑A2.9 evidence binding. | **Adopt.** |
| “Agency” is graded and mediated by active systems + policies. | Cognitive/agentic modeling treats agency as spectrum, mediated by control loops and policies. | Friston et al. (2017), Active Inference; basal cognition surveys (2018+). | Supports separating role labels from behavioural work; aligns with A.13/A.15. | **Adopt (with scope).** Keep obligations in CC. |

> **Note.** Prefer citing a maintained SoTA synthesis pack for roles/contexts if your Context has one.

### A.2:End
  
## A.2.1 - U.RoleAssignment: Contextual Role Assignment

> **Type:** Definitional (D)
> **Status:** Stable
> **Normativity:** Normative

*with `Role Performance View`, `U.RoleStateGraph (RSG)`, and `Role Characterisation Space (RCS)` hooks*

**Builds on:** A.1 **Holonic Foundation**, A.1.1 **`U.BoundedContext`**, A.2 **Role Taxonomy**.  
**Coordinates with:** A.13 **Agential Role & Agency Spectrum**, A.15 **Role–Method–Work Alignment**, E.10.D1 **D.CTX (Context discipline)**, E.10.D2 **Strict Distinction**.  
**Lexical discipline.** *Context* ≡ `U.BoundedContext` (E.10.D1). *Appointment* is **colloquial only**; the canonical term in this specification is **Role Assignment** (see **CC‑LX‑1**).

**Mint vs reuse.** This pattern defines `U.RoleAssignment` and `U.RoleEnactment` and introduces the labels `Role Characterisation Space (RCS)` and `Role State Graph (RSG)` as intensional facets recorded in `RoleDescription` / `RoleSpec`. It reuses existing kernel terms (`U.Holon`, `U.System`, `U.Episteme`, `U.BoundedContext`, `U.Work`, `U.Method`) without changing their meanings.

### A.2.1:1 - Problem frame

**Intent.** Provide one, universal, **context‑local** way to say *who is being what, where (and when)* without altering what the thing **is**. The same grammar works for people, machines, software, teams, and **also** for knowledge artefacts (epistemes) when they hold **statuses** rather than perform actions.

**Scope.**

* Defines **`U.RoleAssignment`** (binding a **holder** holon to a **role** inside a **bounded context**, optionally within a **time window**).
* Separates that binding from **`U.RoleEnactment`** (the run‑time fact that a piece of **Work** was performed under that assignment).
* Names the **Role Characterisation Space (RCS)** and the **Role State Graph (RSG)** as **intensional** facets of a Role (recorded in its `RoleDescription`, upgraded to `RoleSpec` only after tests exist).
* Declares **eligibility** constraints so Roles apply to the right holon kinds, **without badge‑of‑badge chains** like “TransformerRole is assigned to be AgentRole”. If your Context wants taxonomic inheritance between role names, express it with in‑Context role algebra (`≤`), not via chained assignments.
* Declares **eligibility** constraints so Roles apply to the right holon kinds, **without badge‑of‑badge chains** like “TransformerRole is assigned to be AgentRole”. If a Context intends taxonomic inheritance between role names, that relation is expressed in‑Context via role algebra (`≤`), not via chained assignments.

**Non‑goals.** No storage models, no workflows, no org charts. This is a **thinking Standard**; all semantics are notation‑free.


### A.2.1:2 - Problem

1. **Type explosion.** Baking transient function into rigid types (“CoolingPump”, “AuditDeveloper”) violates parsimony and makes change brittle.
2. **Context drift.** Labels like *Operator*, *Process Owner*, *Standard* slide in meaning across teams/years when not tied to a **Context**.
3. **Actor vagueness.** Work logs state that things happened but not **who, in what capacity**, under which **local rules**.
4. **Category leaks.** Documents “do” tasks; deontic statuses are treated like run‑time states; capabilities are confused with permissions.
5. **Role chains.** Attempting “System ↦ TransformerRole ↦ AgentRole” hides intent and smuggles taxonomy into the data plane.


### A.2.1:3 - Forces

| Force                            | Resolution in this pattern                                                                                                        |
| -------------------------------- | --------------------------------------------------------------------------------------------------------------------------------- |
| **Universality vs locality**     | One mechanism (`U.RoleAssignment`), but every meaning is **context‑local** (Context); cross‑context sameness only via **Bridge** (F.9). |

### A.2.1:4 - Solution

#### A.2.1:4.1 - Canonical definition (notation‑free)

**`U.RoleAssignment`** is a **context-local assignment:

```
RoleAssignment ::=
  〈holder: U.Holon,
   role: U.Role,
   context: U.BoundedContext,
   window?: U.Window,
   justification?: U.Episteme,
   provenance?: U.Method〉
```

**Admissibility constraints (concept‑level; non‑deontic).**

* **Invariant RA‑1 (Locality).** `role ∈ Roles(context)`. The role’s meaning is exactly the one recorded in that Context’s RoleDescription/RoleSpec.
* **Invariant RA‑2 (No role‑of‑role).** `holder : U.Holon` and `holder ∉ {U.Role, U.RoleAssignment}`. (Roles/assignments are never holders.)
* **Invariant RA‑3 (Eligibility by role kind).**
  * **Behavioural roles** (agential/transformer/observer/speech and their refinements): `holder` is a `U.System`. Only systems can enact Methods and produce Work.
  * **Status roles** (epistemic‑status / normative‑status / service‑governance): `holder` is a `U.Episteme`. Epistemes never enact Work; they gate and justify.
  * Context refinements may tighten eligibility (e.g., “Approver must be human”) but are restrictions of the System/Episteme split (they do not weaken it).
* **Invariant RA‑4 (Window discipline).** If `window` is present, enactments occur within it. If `window` is absent, interpret the assignment as open‑ended **from an assignment time that is still traceable** (e.g., via an issuing `U.RoleAssigning` SpeechAct Work or other evidence).
* **Invariant RA‑5 (Separation).** A RoleAssignment confers **the capacity/authorization to act** (or the status to be recognised), but it is **not behaviour** (no Work implied), **not capability** (intrinsic ability lives elsewhere), and **not structure** (it does not participate in BoM / part‑of structure).

**Governance metadata (optional but first‑class when present).**

* `justification` carries *why* the assignment is valid in this Context (policy, standard, evidence Episteme).
* `provenance` carries *how* the assignment was issued or verified (method reference; may link to a `U.RoleAssigning` work step in the evidence graph).

**Didactic read.** Think **badge** (*who wears which mask, where, when*). The rules for the mask live **in the room** (Context).

**Two assignment modes.**
A RoleAssignment can be:
(a) Authoritative — issued by an authority or policy in the Context (often via a `U.RoleAssigning` SpeechAct Work); it can open a Green‑Gate for steps that require explicit authorization.
(b) Observational — an evidence‑backed classification that the holder occupies a Role in this Context (e.g., “Moon as SatelliteRole:IAU_2006”). Observational assignments never by themselves open operational Green‑Gates; they can gate decisions and analysis.

#### A.2.1:4.2 - Role Enactment (distinct from the assignment)

**`U.RoleEnactment`** captures the *run‑time* fact that **a specific piece of Work** was performed under **a specific Role Assignment**:

```
RoleEnactment ::= 〈work: U.Work, by: U.RoleAssignment〉
```

**Admissibility constraints (concept‑level; non‑deontic).**

* **Invariant RE‑1 (Actor reality).** `by.holder : U.System`. (Epistemes never enact Work.)
* **Invariant RE‑2 (Temporal fit).** `work.window` overlaps `by.window` (or `by.window` is open and contains `work.window`).
* **Invariant RE‑3 (Method gate).** For the `MethodStep` realised by `work`, `by.role` satisfies the step’s `requiredRoles` in that **same Context** (directly or via `≤` specialization inside the Context).
* **Invariant RE‑4 (Traceability shape).** `U.Work` records cite the performer as `performedBy = some U.RoleAssignment`. `U.RoleEnactment` is the conceptual (or derived) association `〈work, work.performedBy〉`; if a system persists it explicitly, it is 1:1 with Work.

*Reading:* **Assignments authorize; enactments happen.** That single sentence prevents months of muddled logs.

Role Enactment is the occurrence of `U.Work` performed by a `holder` while a valid `U.RoleAssignment` for the required Role is in an enactable state of its RoleStateGraph (A.2.5) within the same Context. Enactment is generic: it includes operational work (e.g., actuation) and communicative work (speech acts such as approvals).

#### A.2.1:4.3 - Role Characterisation Space (RCS) & Role State Graph (RSG)

These are **intensional facets** of a **Role**, not containers “inside” the Role. They are **recorded in** the **RoleDescription** (or **RoleSpec** once harnessed), per E.10.D2.

* **RCS (Role Characterisation Space).** A set of named characteristics that parameterise how the Role is understood in a Context (e.g., *AgencyLevel ∈ {None, Assisted, Delegated, Autonomous}*; *SafetyCriticality ∈ {SC0…SC3}*).
* **RSG (Role State Graph).** A directed graph of **named states** (nodes) and **admissible transitions** (edges) for the Role **within the Context** (e.g., *{Eligible → Authorized → Active → Suspended → Revoked}*).

  * Each **state** has a **Conformance Checklist** (set of observable cues) supporting **Evaluations** (“X ∈ *Authorized*@context in W”).
  * RSG governs **role state transitions**, independent of any Work instance.

**Discipline.** Prefer the phrasing *“Role is **characterised by** RCS/RSG recorded in RoleDescription”*; avoid “Role **contains** its states.”


#### A.2.1:4.4 - Shorthand & reading

The canonical compact form used in prose and diagrams is:

```
Holder#Role:Context@Window
```

Examples:

* `PLC_17#Transformer:PipelineOps@2025‑04‑01..2025‑06‑30`
* `ISO_26262v2018#NormativeStandard:AutoSafetyCase` *(status role on an Episteme; no enactment)*

*The shorthand is didactic; the semantics are those of §§4.1–4.3.*


#### A.2.1:4.5 - No role chains (use algebra, not badge‑of‑badge)

Chained assignments are ill‑formed for encoding taxonomy (see **Invariant RA‑2** and **CC‑ELIG‑3**). Chaining hides intent and defeats validation.

Taxonomic inheritance between role names is declared explicitly in the Context’s role algebra. For example, if (per A.13) your Context treats every transformer as a kind of agent, state:

* `TransformerRole ≤ AgentialRole` *(in that Context’s role algebra)*

When a MethodStep requires two independent roles, express the conjunction where it belongs:

* the **MethodStep** requires both roles; the holder **wears two badges**, not a badge‑of‑a‑badge.

#### A.2.1:4.6 - Eligibility across holon kinds (normative matrix)

A Role’s **family** constrains **who can wear its badge**. Eligibility is part of **didactic hygiene** and prevents chains like “Transformer → Agent”.

##### A.2.1:4.6.1 - Holder kinds (recap)

* **`U.System`** — any acting holon (person, device, software service, team, organization, socio‑technical unit).
* **`U.Episteme`** — any knowledge unit (document, dataset, model, standard, Standard).
* **`U.Holon`** — supertype; only **Systems** enact Work; **Epistemes** can only hold **status** roles.

##### A.2.1:4.6.2 - Role‑kind × holder matrix

| Role kind (examples)                                                     | May be held by `U.System` | May be held by `U.Episteme` | Notes (eligibility refinements live in Context)                                                                                |
| ------------------------------------------------------------------------ | :-----------------------: | :-------------------------: | ------------------------------------------------------------------------------------------------------------------------------ |
| **Agential** (e.g., *Agent*, *Decision‑Maker*, *Approver*)               |           **✓**           |              ✗              | Requires an RCS characteristic such as *AgencyLevel*; RSG should expose *Authorized/Active* states.                            |
| **Transformer/Constructor** (e.g., *Welder*, *ETL‑Runner*)               |           **✓**           |              ✗              | Performs Methods; produces Work; often requires *Capability* evidence.                                                         |
| **Observer/Measurer** (e.g., *Observer*, *Monitor*)                      |           **✓**           |              ✗              | Produces `U.Observation`; may be passive (probe) or active (test rig).                                                         |
| **Communicator/Speech** (e.g., *Authorizer*, *Notifier*)                 |           **✓**           |              ✗              | A behavioural role; produces `U.Work` typed as SpeechAct.                                                                      |
| **Service‑Governance** (e.g., *ServiceOffering*, *SLO‑ClauseCarrier*)    |             ✗             |            **✓**            | **Episteme** (catalog entry, policy). If a System “offers”, the *offer* is a SpeechAct; the *offering* is an Episteme.         |
| **Epistemic‑Status** (e.g., *Evidence*, *Definition*, *AxiomaticCore*)   |             ✗             |            **✓**            | Status roles for knowledge; never enact Work.                                                                                  |
| **Normative‑Status / Deontic** (e.g., *Requirement*, *Standard*)         |             ✗             |            **✓**            | Source of obligations; Work is checked **against** them, not enacted by them.                                                  |

**Invariant — RA‑3 (eligibility)** *(restated)*: RoleAssignments are ill‑formed if they violate this matrix. A Context may **tighten** (e.g., “Approver must be human”), never loosen.

**Conformance checks (easy to remember).**

* **CC‑ELIG‑1.** If `role.family ∈ {Agential, Transformer, Observer, Speech}`, then `holder : U.System`.
* **CC‑ELIG‑2.** If `role.family ∈ {Epistemic‑Status, Normative‑Status, Service‑Governance}`, then `holder : U.Episteme`.
* **CC‑ELIG‑3.** No “role of a role”: `role` is bound to a **holder**, not to another role or assignment.


#### A.2.1:4.7 - Role algebra within a single Context (meaning relations)

Role algebra 

The in‑Context role algebra relates **role types** inside **one** `U.BoundedContext`. It is **not** mereology. Its operators (`≤`, `⊥`, `⊗`) is specified normatively in **A.2.7 `U.RoleAlgebra`**.

A.2.1 relies on it for (i) `requiredRoles` substitution checks (`≤`), (ii) separation‑of‑duties validation (`⊥`), and (iii) conjunctive bundles (`⊗`), but does not restate the operator semantics here.

#### A.2.1:4.8 - Time & state transition calculus (windows, RSG, enactability)

**Assignments authorize**, **enactments happen** — in time. RSG governs the **role’s** state transitions; `window` governs the **binding’s** validity.

##### A.2.1:4.8.1 - Windows and overlap

* **Window form:** `@t_start..t_end` (ends may be open).
* **RE‑2 (temporal fit)** *(restated)*: `work.window` lies within (or overlaps appropriately with) `assignment.window`.
* **Handover pattern:** Close `A#Role@..t` and open `B#Role@t..` — history is preserved by closing windows rather than deletion.
* **(Conformance hook.)** See **CC‑WIN‑1**: preserve history by closing windows rather than erasing RoleAssignments.

##### A.2.1:4.8.2 - RSG gating of enactment

Each Role’s **RoleDescription/RoleSpec** defines an **RSG** with named states; some states are **enactable**.

* **Delegation.** Normative author‑facing requirements for `U.RoleStateGraph` structure (including enactability marking and per‑state checklists) and the shape of `StateAssertion` evidence are defined in **A.2.5**; A.2.1 only relies on the resulting enactment gate.
* **Invariant RE‑5 (RSG gate).** A `U.RoleEnactment` is valid **iff** at enactment time the `U.RoleAssignment` can be supported by a **valid StateAssertion** that the holder is in an **enactable** state of the Role’s RSG **in this Context**.
* **(A.2.5 hook.)** The Role’s `U.RoleStateGraph` (A.2.5) identifies enactable states and attaches a Conformance Checklist to each state; checklist verdicts can be recorded as `StateAssertion`s (see SCR‑A2.5‑S02/S03).
* **Example.** *SurgeonRole* states: *Eligible → Authorized → Active → Suspended → Revoked*. Only **Active** is enactable. A pre‑op checklist produces `StateAssertion(SurgeonRole, Active)`.

**Practical reading.** *Badge valid* (window) ∧ *state is right* (RSG) ⇒ you may act.

##### A.2.1:4.8.3 - Suspensions, revocations, probation

* **Suspend:** transition to a **non‑enactable** state (e.g., *Suspended*). Keep the assignment’s window open; enactment is blocked by **RE‑5**.
* **Revoke:** either (a) close the window, or (b) transition to *Revoked* (non‑enactable).
* **Probation:** a dedicated RSG state with limited enactability (e.g., only under supervision, modelled as an extra required role on Method steps).
* **Discipline (A.2.5).** RSG transitions are explicit; no implicit “back to Active”.

##### A.2.1:4.8.4 - Typical temporal patterns (didactic)

* **Shift rotation.** `A#Role@08:00..16:00`, `B#Role@16:00..24:00` — clean handover, no `⊥` issues.
* **Shadowing.** `Trainee#Role@..` + `Mentor#SupervisorRole@..`; Method steps require **both** roles.
* **Emergency bundle.** `SoloOperator := Incision ⊗ Hemostasis ⊗ Suturing`; activate only under declared emergency (Context‑level policy).

#### A.2.1:4.9 - Integration with A.15 (Role–Method–Work alignment)

> **One line.** A `U.MethodDescription` names the roles it needs; a `U.Work` cites the concrete `U.RoleAssignment` that enacted the step; the RSG state + window gates that enactment.

##### A.2.1:4.9.1 - Design‑time Standard (inside `U.MethodDescription`)

For every **MethodStep**:

* **`requiredRoles`** — a list of `U.Role` **from the same Context as the step**.
  *Example.* In `Hospital.OR_2025`, step “Make incision” has `requires: [IncisionOperatorRole]`.
* Role algebra in‑Context applies: if the Context defines `IncisionOperatorRole ≤ SurgeonRole`, then `requires: [SurgeonRole]` also admits holders of `IncisionOperatorRole`.
* **Separation of concerns.** Capability checks (does the holder *can*?) belong to `U.Capability` and resource limits; **authorization** belongs to `U.RoleAssignment` + RSG.

##### A.2.1:4.9.2 - Run‑time check (inside `U.Work`)

A `U.Work` record provides (or allows derivation of) the fields needed to satisfy **CC‑ENACT‑1..3**:

* **`performedBy` =** a concrete **`U.RoleAssignment`** (not just a person/system name).
* **Window gate.** The Work timestamp falls inside the assignment’s `@Window`.
* **State gate.** At that timestamp, an **enactable** state for the assignment is proven by a **`StateAssertion`** (the checklist verdict for a named RSG state).
* **Role algebra gate.** The assignment’s `role` is either one of `requiredRoles` or a **specialization (`≤`)** thereof; bundles (`⊗`) expand to conjunctions; incompatibilities (`⊥`) forbid overlaps on the same holder.

##### A.2.1:4.9.3 - Evaluation & acceptance (link to services & deontics)

* **Observation.** The Work produces `U.Observation`(s).
* **Evaluation.** A `U.Evaluation` compares Observations with **AcceptanceClause**(s) referenced by a **Service** or a **RequirementRole**.
* **SoD hook.** If the step or evaluation demands independence (e.g., “not performed by its reviewer”), enforce via `⊥` between `PerformerRole` and `ReviewerRole` **in the same Context**.

##### A.2.1:4.9.4 - Planning & scheduling (design‑time “who will enact”)

* **`U.WorkPlan`** (aka “WorkDescription” in prose) binds forthcoming steps to **candidate RoleAssignments** and time windows.
* **Checks before the fact.** Validate windows (no gaps/overlaps where disallowed), enforce `⊥`, ensure expected RSG state will be **enactable** at scheduled time (or flag a pre‑flight checklist).

> **Didactic cue.** Think **“Step asks for badges; Run cites a badge; Badge must be valid & green.”**
> (Badge = RoleAssignment; valid = window; green = RSG state with a fresh StateAssertion.)

#### A.2.1:4.10 - Cross‑Context bridges in practice (with CL penalties)

Cross‑Context role substitution is **Bridge‑only** and is specified in **F.9** (with CL/waiver regimes) and **B.3** (CL‑penalty routing).

A.2.1’s only rule is *no substitution by label*: any “`Role_B@B` satisfies `Role_A@A`” claim used for checking or enactment **MUST** cite an explicit Bridge (direction, CL, loss notes) and **MUST NOT** override in‑Context `≤`, `⊥`, or `⊗`.

#### A.2.1:4.11 - Everyday pattern snippets (didactic moves)

> **Use these micro‑moves to think and speak cleanly; no tooling required.**

1. **“Who can do this step?”**
   On a `MethodStep`, write `requires: [RoleX]`. In your head, expand: “Any `performedBy` whose `role ≤ RoleX`, with a **valid window** and **enactable RSG state**.”
   *Example:* `requires: [SurgeonRole]` and `IncisionOperatorRole ≤ SurgeonRole` ⇒ `Dr.Kim#IncisionOperatorRole:Hospital.OR_2025` is admissible **iff** Active.

2. **Handover without history loss.**
   Close one window, open another. Never delete.
   `Alex#IncidentCommander:SRE_Prod@08:00..12:00`
   `Riya#IncidentCommander:SRE_Prod@12:00..20:00`

3. **Independence by construction (SoD).**
   Declare `Developer ⊥ IndependentAuditor`. Then it’s **impossible** (by validation) to have overlapping windows on one holder for both roles.

4. **Supervision as bundle.**
   Model apprenticeship by requiring `Trainee ⊗ Supervisor` on sensitive steps, or by RSG state **Probation** that flips `enactable` only if `SupervisorRole` is also present.

5. **Same badge name in two Contexts.**
   `LeadEngineer:ProjectPhoenix` ≠ `LeadEngineer:DivisionR&D`. If you must relate, create a **Bridge** with CL & loss notes; never rely on the name.

6. **Documents don’t act; they frame.**
   Replace “the SOP executed X” with: `SOP_v4#RequirementRole:SafetyCase` and a `SpeechAct` “approve run” by `QA_Officer#AuthorizerRole:Plant_2025`.

7. **Window + state ⇒ permission.**
   Quick mental check: *badge valid?* (window) ∧ *state OK?* (RSG) ⇒ **go**; else **no‑go**.

8. **Communicative enactment (approval)**
`CAB_Chair#ApproverRole:ChangeControl@2026-05-01T10:05` performs a SpeechAct Work “Approve Change-4711”. Effect: moves ApproverRole’s RSG state from Authorized?→Approved and
   opens the Green‑Gate for the operational step “Deploy Change-4711” (performed by a different RoleAssignment).

### A.2.1:5 - Archetypal Grounding (three disparate arenas)

**Goal.** Show that the same assignment **`Holder#Role:Context@Window`**, plus **RCS** (Role-Characterisation Space) and **RSG** (Role-State Graph), works uniformly for **operational systems**, **software/service operations**, and **knowledge governance**.

Natural systems note. Spontaneous physical phenomena (e.g., Moon orbiting Earth) are modeled as `U.Dynamics`, not as `U.Work`. An observational RoleAssignment like `Moon#SatelliteRole:IAU_2006` is valid classification but does not imply enactment of a method.

#### A.2.1:5.1 - Industrial operations (welding cell)

**Role (family).** `WelderRole` *(Transformer)*
\**RCS (illustrative characteristics).*

* `ProcessClass ∈ {MIG, TIG, Spot}`
* `QualifiedMaterial ∈ {Al, SS, Ti, …}`
* `MaxCurrentAmp ∈ ℝ⁺`
* `SafetyProfile ∈ {Standard, HotWork, ConfinedSpace}`

**RSG (named states).**
`Unqualified → Qualified → Authorized → Active → Suspended → Revoked`
(*enactable*: **Active** only)

**Assignments.**

* `Robot_SN789#WelderRole:AssemblyLine_2025@2025‑02‑01..open`
* `Robot_SN790#WelderRole:AssemblyLine_2025@2025‑02‑01..open`

**StateAssertions (via checklists).**

* `StateAssertion(WelderRole, Qualified, AssemblyLine_2025, @2025‑02‑01..2026‑02‑01)` — training & test weld coupons.
* `StateAssertion(WelderRole, Active, AssemblyLine_2025, @2025‑03‑01..open)` — daily pre‑shift checks + gas/torch inspection.

**Enactment (gated by RSG).**
A `U.Work` entry `W#Seam134` is valid only if `performedBy = Robot_SN789#WelderRole:AssemblyLine_2025` and an **Active** `StateAssertion` covers the timestamp. If the torch‑health checklist fails, RSG transitions `Active → Suspended`; further seams are blocked by **RE‑5**.


#### A.2.1:5.2 - Software & cloud operations (continuous delivery / SRE)

**Roles (families).**

* `DeployerRole` *(Transformer)* — authorises execution of deployment Methods.
* `IncidentCommanderRole` *(Agential/Speech)* — directs response and issues SpeechActs (declares incident states).

**RCS (illustrative).**

* `DeployerRole`: `Env ∈ {staging, prod}`, `ChangeWindow`, `RollbackAuthority ∈ {self, peer, CAB}`.
* `IncidentCommanderRole`: `OnCallTier ∈ {L1,L2,L3}`, `ServiceScope`, `PageDuty ∈ {primary, secondary}`.

**RSGs (named states).**

* `DeployerRole`: `Eligible → Authorized → Active → Suspended` (*enactable*: **Active**).
* `IncidentCommanderRole`: `OnCall → Engaged → Handover → Rest` (*enactable*: **Engaged**).

**Assignments.**

* `sCG‑Spec_ci_bot#DeployerRole:CD_Pipeline_v7@2025‑04‑01..open`
* `Alex#IncidentCommanderRole:SRE_Prod@2025‑04‑10T08:00..2025‑04‑10T20:00`

**StateAssertions (via checklists).**

* `DeployerRole/Active`: completed change ticket, green pre‑deploy tests, peer‑review check mark.
* `IncidentCommanderRole/Engaged`: accepted page, situational brief read, comms‑channel opened.

**Enactment.**

* A deployment `Work` is valid only with `performedBy: sCG‑Spec_ci_bot#DeployerRole:CD_Pipeline_v7` **and** `Active` state asserted for the moment of start.
* Declaring `Incident SEV‑1` is a **SpeechAct Work** performed by `Alex#IncidentCommanderRole:SRE_Prod` in **Engaged** state; it changes deontic conditions (e.g., elevates `RollbackAuthority`).


#### A.2.1:5.3 - Knowledge governance (standards & requirements)

**Roles (families).**

* `NormativeStandardRole` *(Normative‑Status Episteme)* — a document that is *the* standard **in this Context**.
* `RequirementRole` *(Deontic‑Status Episteme)* — a statement that **binds** behaviour in this Context.

**RCS (illustrative).**

* `NormativeStandardRole`: `Scope`, `Edition`, `ApplicabilityWindow`.
* `RequirementRole`: `BindingClass ∈ {shall, should, may}`, `TargetRole`, `AcceptanceClauseRef`.

**RSGs (named states).**

* `NormativeStandardRole`: `Proposed → Adopted → Effective → Superseded` (*enactable*: N/A — Episteme roles are **non‑enactable**; they gate others).
* `RequirementRole`: `Draft → Approved → Effective → Retired` (non‑enactable).

**Assignments.**

* `ISO_26262_ed2.pdf#NormativeStandardRole:AutoSafetyCase_2025@2025‑01‑01..open`
* `REQ‑BRAKE‑001.md#RequirementRole:AutoSafetyCase_2025@2025‑03‑05..open`

**Effects (gating, not acting).**

* A system’s **Work** (e.g., HIL test run) is **evaluated** against clauses referenced by `RequirementRole`.
* An **Approval SpeechAct** (by a CAB chair who is a `U.System`) may transition `RequirementRole: Draft → Approved`. The Episteme does not “act”; **Systems** act, **Epistemes** hold status.

### A.2.1:6 - Bias-Annotation

Lenses tested: **Arch**, **Onto/Epist**, **Socio‑tech**, **Prag**, **Did**. Scope: **Kernel** (A‑cluster).

* **Architecture bias (Arch):** treating roles/assignments as structural parts can smuggle function into mereology and break holarchies.  
  *Mitigation:* keep roles out of BoM/structure trees; close windows instead of deleting history.

* **Onto/Epist bias (Onto/Epist):** anthropomorphising epistemes collapses evidence into agency (“the SOP approved”).  
  *Mitigation:* only Systems enact Work; Epistemes may justify, constrain, and gate; enforce RE‑1 and CC‑SD‑2.

* **Socio‑technical bias (Socio‑tech):** role eligibility rules can silently encode exclusion, power asymmetries, or discrimination (e.g., “Approver must be X” with no rationale).  
  *Mitigation:* keep eligibility refinements explicit in the Context, recorded as Episteme policy, and review them under D.2/D.* ethics patterns; prefer capability/competence evidence over demographic proxies.

* **Pragmatic bias (Prag):** over‑localising role labels can fragment reuse and create naming drift.  
  *Mitigation:* require explicit `:Context` binding and explicit Bridges with CL/loss notes instead of silent equivalence.

* **Didactic bias (Did):** metaphors (“badge”, “mask”, “green gate”) may be misread as informal or security‑only.  
  *Mitigation:* bind obligations to the Conformance Checklist; keep metaphors as mnemonic only.

### A.2.1:7 - Conformance Checklist (normative)

#### A.2.1:7.1 - SCR (compact, memorable)

> **Pass these and your RoleAssignments are sound.**

**Anchoring & locality**

1. **CC‑CTX‑1.** A conformant model/record **MUST** ensure that every RoleAssignment’s `role` names a role defined in the same `U.BoundedContext` as that assignment.
2. **CC‑CTX‑2.** Authors and validators **MUST NOT** assume cross‑Context equivalence by label; any cross‑Context relation used for substitution or checking **MUST** be represented only in **Bridges** (F.9).

**Eligibility & families**
3\. **CC‑ELIG‑1.** Validators **MUST** reject any RoleAssignment record where `role.family ∈ {Agential, Transformer, Observer, Speech}` but `holder :̸ U.System`.
4\. **CC‑ELIG‑2.** Validators **MUST** reject any RoleAssignment record where `role.family ∈ {Epistemic‑Status, Normative‑Status, Service‑Governance}` but `holder :̸ U.Episteme`.
5\. **CC‑ELIG‑3.** Validators **MUST** reject any RoleAssignment record whose `holder ∈ {U.Role, U.RoleAssignment}` (no badge‑of‑badge chains).

**Role algebra (in‑Context)**
See **A.2.7 `U.RoleAlgebra`** (CC‑ALG‑1, 2, 3).

**Time & gating**
9\. **CC‑WIN‑1.** Record‑keeping systems and models **MUST NOT** delete historic RoleAssignment records; they close windows instead. If `window` is absent, the record **MUST** retain a traceable assignment start time (e.g., via a `U.RoleAssigning` SpeechAct Work or other evidence).
10\. **CC‑ENACT‑1.** Conformant Work records **MUST** cite `performedBy = some U.RoleAssignment`; validators **MUST** be able to check that the Work interval fits the assignment window (or that an open‑ended window contains it).
11\. **CC‑ENACT‑2.** At the Work time, validators **MUST** be able to (a) locate/derive a **StateAssertion** supporting an **enactable** RSG state for the cited assignment, and (b) verify that the assignment’s `role` satisfies the executed MethodStep’s `requiredRoles` in that **same Context** (directly or via `≤`; `⊗` expands to conjunctions).
12\. **CC‑ENACT‑3.** Runtime gates and validators **MUST** block enactment while the assignment lacks a supporting **StateAssertion** for an enactable state (e.g., during **Suspended**).

**Strict distinction & category hygiene**
13\. **CC‑SD‑1.** Models and tools **MUST NOT** place Roles into BoM/structure trees; roles do not participate in mereology.
14\. **CC‑SD‑2.** Models and tools **MUST NOT** treat Epistemes as Work actors; validators **MUST** enforce **RE‑1** (`by.holder : U.System`).

**Lexical hygiene**
15\. **CC‑LX‑1.** Authors **MUST NOT** use *appointment* as a synonym for *Role Assignment* in normative clauses.

**Traceability**
16\. **CC‑TRC‑1.** From any `U.Work`, reviewers **MUST** be able to trace **performedBy → RoleAssignment → Role → (RCS,RSG) → Context** and retrieve supporting **StateAssertion** evidence.

#### A.2.1:7.2 - RSCR (regression harness)

> **Run these mental “diff checks” whenever you change roles, contexts, or states.**

**RSG & gating**

* **RSCR‑RSG‑E01.** After editing an RSG, verify that each enactable state still has a live **Conformance Checklist** and that historic **StateAssertions** remain interpretable (no silent renames).
* **RSCR‑RSG‑E02.** If a state flips *enactable⇄non‑enactable*, re‑evaluate pending or recurring `U.Work` plans (no hidden authorisations).

**SoD & windows**

* **RSCR‑SOD‑E01.** On adding `⊥` constraints, scan for overlapping assignments that newly violate SoD; schedule revocations or rescheduling.
* **RSCR‑SOD‑E02.** On removing `⊥`, confirm that governance rationale is recorded elsewhere (policy change Episteme).

**Context churn**

* **RSCR‑CTX‑E01.** When a Context edition updates, freeze prior RoleAssignments; create **new** assignments in the new Context rather than mutating old ones.
* **RSCR‑CTX‑E02.** Bridges referencing affected roles are reviewed for CL/loss adjustments.

**Eligibility drift**

* **RSCR‑ELIG‑E01.** If a role family changes (e.g., reclassifying *Offerer* from behavioral to status), audit all assignments for holder‑type violations.

**Trace continuity**

* **RSCR‑TRC‑E01.** Spot‑check that `U.Work → RoleAssignment → StateAssertion` chains still resolve after refactors.
* **RSCR‑TRC‑E02.** Randomly sample old incidents/runs to ensure reproducible authorisation verdicts.

**Name stability**

* **RSCR‑NAME‑E01.** If a role label changes, maintain the **role identity**; treat renamed labels as aliases inside the same Context rather than minting a new role unless RCS/RSG changed materially.

### A.2.1:8 - Common Anti-Patterns and How to Avoid Them

| #      | Anti‑pattern          | Symptom                                    | Why it’s harmful                   | FPF fix (conceptual move)                                         |
| ------ | --------------------- | ------------------------------------------ | ---------------------------------- | ----------------------------------------------------------------- |
| **A1** | **Global role label** | “Alice is Lead Engineer” (nowhere)         | Meaning drifts; untestable         | Always anchor to Context: `Alice#LeadEngineer:ProjectPhoenix`      |
| **A2** | **Role as part**      | BoM lists “Cooling Function”               | Category error (structure vs role) | Keep BoM structural; model `Pump#Cooling:ThermalMgmt`              |
| **A3** | **Document acts**     | “The SOP closed the ticket”                | Epistemes don’t enact Work         | Give the doc a status role; make a System enact the step           |
| **A4** | **Role chains**       | “Transformer assigned to be Agent”         | Hides taxonomy; defeats checks     | Use role algebra (`≤`) and/or require both roles on the Method step |
| **A5** | **Hidden state**      | Acting while *Authorized? Active?* unclear | Safety & audit gaps                | Use RSG with StateAssertions gating enactment                      |
| **A6** | **Edition blur**      | Context “ITIL” with no version             | Sense slippage                     | Context card must carry edition (E.10.D1/F.1)                      |
| **A7** | **Bridge‑by‑name**    | Equating roles across Contexts by label    | Cross‑context drift                | Use F.9 Bridge with CL & loss notes                                |
 
### A.2.1:9 - Consequences

**Benefits**

1. **No type explosion.** Structure stays stable; function lives in RoleAssignments with small, local lattices.
2. **Traceable authority.** Every `U.Work` has a clean chain: **performedBy → RoleAssignment → Role → (RCS,RSG) → Context**.
3. **Safe heterogeneity.** Different Contexts can use the same badge name differently; conflicts are dissolved by locality and explicit Bridges.
4. **Didactic economy.** One mental form — `Holder#Role:Context@Window` — covers factories, clouds, labs, and libraries.
5. **Strong SoD.** Incompatibilities (`⊥`) and bundles (`⊗`) are first‑class; audits become mechanical.
6. **Assurance‑ready.** RSG + StateAssertions convert checklists into **explicit gates**; CL penalties quantify Cross‑context risk.
7. **Temporal honesty.** Windows encode the ebb and flow of assignments without history loss.

**Costs / discipline required**

1. **RoleDescription work.** Each Context needs a minimal RoleDescription (name, RCS, RSG, checklists).
2. **Bridge authorship.** Cross‑context work requires explicit Bridges with CL & loss notes.
3. **Vocabulary hygiene.** Teams must stop using context‑less role labels.

#### A.2.1:9.1 - Teaching distillation (60‑second recap)

> “Give every action a badge with a Context. The badge is a `U.RoleAssignment`: `Holder#Role:Context@Window`.
> The badge is valid in time (window) and green in state (RSG + StateAssertion).
> A Method step names the badges it needs; a Work cites the exact badge that enacted it.
> If a badge comes from another Context, cross with a Bridge and respect its CL penalty.
> Keep SoD with `⊥`, reuse expertise with `≤`, and require combos with `⊗`.
> Documents don’t act — they hold status roles; only systems enact Work.
> With this, factories, clouds, and knowledge all speak the same, small grammar.”

#### A.2.1:9.2 - So what? Adoption test (1 minute)

If a team claims to “use A.2.1”, a random audit sample should pass all of these in minutes:

1. **Badge locality:** every role label is always read as `Role:Context` (or explicitly bridged), never as a global name.
2. **Work attribution:** each sampled `U.Work` cites a concrete `performedBy = U.RoleAssignment`, not just a person/system string.
3. **Window + state gate:** at the Work time, the assignment window fits and an enactable RSG `StateAssertion` exists (or the run is correctly blocked/exceptioned).
4. **No badge‑of‑badge:** no assignment ever binds a `U.Role` or `U.RoleAssignment` as its holder.
5. **Status hygiene:** no Episteme (Standard/Requirement/Evidence) is ever an actor of Work; it only gates/justifies/evaluates.

### A.2.1:10 - Rationale

* **Strict Distinction (A.7).** Keeps **identity** (Holon) separate from **assignment** (RoleAssignment), **behaviour** (Method/Work), and **knowledge** (Episteme).
* **Ontological Parsimony (A.11).** One universal binding, three tiny in‑Context relations (`≤, ⊥, ⊗`), no global role types.
* **Universal core (A.8).** The same mechanism works across systems (machines, software, teams) and epistemes (standards, requirements), demonstrated in §5.
* **Lexical discipline (E.10.D1 & E.10.D2).** Roles are **context‑local**; descriptions (RCS, RSG) are **descriptions of intensional roles**, not the roles themselves.
* **Assurance posture.** Windows + RSG + StateAssertions make authorisation explicit and reviewable; Bridges + CL make cross‑Context reuse explicit and risk‑graded (B.3).

### A.2.1:End


## A.2.2 — U.Capability

### A.2.2:1 - Context (plain‑language motivation)

In real projects we must answer two different questions:

* **“Can this system do X?”** — this is about an **ability** inherent to the system.
* **“Is this system assigned to do X here and now?”** — this is about an **assignment** (a **Role assignment**) inside a bounded context.

Teams frequently blur the two, and then further mix them with **how** the work is done (the **Method**) and **what actually happened** (the **Work**). `U.Capability` isolates **ability as a first‑class concept** so that you can plan realistically, staff responsibly, and audit cleanly.

### A.2.2:2 - Problem (what goes wrong without this concept)

1. **Permission ≠ ability.** A Role assignment authorizes execution in a context; it does **not** prove the system can meet the required **WorkScope** and **WorkMeasures**.
2. **Recipe ≠ ability.** A Method says *how* to do something; it does not guarantee that *this* holder can meet the target outcomes under the required constraints.
3. **Execution log ≠ ability.** A past Work record does not, by itself, establish a stable ability; conditions may have been favorable or unique.
4. **Cross‑team confusion.** Enterprise terms like “capability”, “service”, and the old “function” are used interchangeably; planning, staffing, and assurance become fragile.


### A.2.2:3 - Forces (what we must balance)

| Force                                   | Tension we resolve                                                                                                                   |
| --------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| **Stability vs. change**                | Ability is a relatively stable property of a system, yet it evolves with upgrades, wear, calibration, and environment.               |
| **Universality vs. domain‑specificity** | One universal notion must serve robots, teams, and software services, while letting each domain keep its own performance vocabulary. |
| **Evidence vs. simplicity**             | We want an ability claim to be evidence‑backed, but the core idea must stay simple enough for planning conversations.                |
| **Local conditions vs. reusability**    | Ability depends on conditions (inputs, environment); still, the concept must be reusable across contexts via explicit scoping.       |


### A.2.2:4 - Solution — define the ability explicitly

#### A.2.2:4.1 Definition
**`U.Capability`** is a **dispositional property of a `U.System`** that states its **ability to produce a class of outcomes** (i.e., execute a class of Work) **within a declared `U.WorkScope` (conditions/assumptions) and meeting stated `U.WorkMeasures`**. It is **not** an assignment (Role), **not** a recipe (Method), and **not** an execution (Work).

> **One-liner to remember:** *Capability = “can do (within its **WorkScope** and measures)”*, independent of *“is assigned now”* or *“did do at time t”*.

**Capability declaration (summary).** A capability SHALL declare, as **separate** items:
* **`U.WorkScope`** (*Work scope*) — the set of `U.ContextSlice` under which the capability can deliver the intended `U.Work` (see **A.2.6 §6.4**);
* **`U.WorkMeasures`** — measurable targets with units evaluated on a **JobSlice** (R‑lane facet);
* **`U.QualificationWindow`** — the time policy that governs operational admissibility at **`Γ_time`** (R‑lane facet).
**Note.** This separation supersedes the legacy “envelope + measures + validity interval” bundle. **Work scope is the set of conditions (USM), not a Characteristic; measures are CHR‑characteristics; capability packages both.**

**Reminder (measurement & scope).** *WorkScope* is a **set‑valued USM object** (membership, set algebra) and **not** a CHR Characteristic; *WorkMeasures* are **CHR Characteristics** with declared scales/units. **Admission checks these separately** (see § 10.3 WG‑2/WG‑3).

#### A.2.2:4.2 Conceptual descriptors (not a data schema)

When you describe a capability in a model or a review, anchor it by answering these five didactic prompts:

1. **Holder:** *Whose ability is this?* → a specific `U.System`.
2. **Context:** *In which bounded context were the measures established?* → `U.BoundedContext` (strongly recommended for clarity and comparability).
3. **Task family:** *Ability to do **what kind** of work?* → reference the relevant **MethodDescription**(s) or method family the system can execute.
4. **WorkScope:** *Under what conditions?* → inputs/resources/environment assumptions (e.g., voltage, pressure, ambient, tool head).
5. **Performance measures:** *With what bounds?* → CHR‑style measures (throughput, precision, latency, reliability, MTBF…) with ranges/targets.

Optional descriptors that improve trust without adding bureaucracy:

* **QualificationWindow:** calibration/qualification window for the stated **WorkScope** (abilities drift).
* **Evidence:** links to test reports, certifications, prior Work summaries (as **Episteme**).
* **Degradation/upgrade notes:** known change points that affect the **WorkScope**.

> **Didactic guardrail:** Capabilities are stated in **positive, measurable terms** (“can weld seam type W at ±0.2 mm up to 12/min at 18 °C–30 °C”). Avoid role words (“welder”) or recipe detail (step flows) here.

#### A.2.2:4.3 Shorthand for everyday speech

To keep discussions terse yet precise, teams often write:

* **“S#17 can \<MethodDescription / task family> @ \<WorkScope> → \<measures>.”**
* Or as a bullet in a capability table scoped to a context, e.g., *AssemblyLine\_2025 Capability Sheet*.

This is not a formal notation—just a consistent way to keep the five prompts in view.

### A.2.2:5 - Clear distinctions (litmus tests managers can apply)

| If you are talking about…                  | Use                     | Litmus test                                                                                  |
| ------------------------------------------ | ----------------------- | -------------------------------------------------------------------------------------------- |
| **assignment** (who is being what, where) | **Role → Role assignment** | Can you reassign to another holder without changing the system’s composition? If yes → Role. |
| **Ability** (can do within bounds)         | **Capability**          | Would you still say “can do” even if not currently assigned? If yes → Capability.           |
| **Recipe** (how‑to)                        | **Method / MethodDescription** | Has inputs/outputs and steps but no date/time.                                               |
| **Execution** (what happened)              | **Work**                | Has a start/end, consumed resources, left a log.                                             |
| **External promise**                       | **Service**             | Framed as “we provide/guarantee to others.”                                                  |
| **Law/model of change**                    | **Dynamics**            | Describes state evolution, not an ability of one system.                                     |

**Two useful corollaries**

* A step in a Method may **require** a Role; **optionally** it may also stipulate a **capability threshold** (e.g., precision ≤ 0.2 mm). assignment and ability are checked separately.
* A Service depends on **having** the needed capabilities **and** being **assigned** to deliver under the Service’s context.


### A.2.2:6 - Archetypal grounding (parallel structural and organizational examples)

#### A.2.2:6.1 Physical system on a line (structural example)

* **Holder:** `RobotArm_A` (`U.System`).
* **Task family:** seam welding per `Weld_MIG_v3` **MethodDescription**.
* **WorkScope:** workpiece steel grades S235–S355; ambient 18–30 °C; argon mix 92–95 %; torch T‑MIG‑07.
* **Measures:** bead width 6.0 mm ± 0.2 mm; throughput ≤ 12 seams/min; defect rate < 0.5 %.
* **Context:** `AssemblyLine_2025`.
* **Readable claim:** *RobotArm\_A can execute Weld\_MIG\_v3 within the stated **WorkScope** at the stated measures (AssemblyLine\_2025).*
* **What this is not:** It is **not** “the welder”—that is a **Role assignment** when assigned on a shift. It is **not** the weld recipe— that is the **MethodDescription**.

#### A.2.2:6.2 Software service in operations (structural, cyber-physical)

* **Holder:** `PlannerService_v4` (deployed system).
* **Task family:** job‑shop schedule generation per `JS_Schedule_v4` MethodDescription.
* **WorkScope:** 50–500 jobs; 5–40 machines; hard deadlines only; network latency ≤ 20 ms.
* **Measures:** schedule completion within 0.95 of theoretical optimum (benchmark set), 98 % on‑time delivery in simulation.
* **Context:** `PlantScheduling_2025`.
* **Use:** Steps that “require ScheduleGeneration capability ≥ 0.90 optimality” will only pass if the holder’s capability meets or exceeds that bound.

#### A.2.2:6.3 Organizational unit (enterprise sense)

* **Holder:** `FinanceDept` (`U.System` as OrgUnit).
* **Task family:** period close per `CloseBooks_v3` MethodDescription.
* **WorkScope:** IFRS; ERP v12; 8 legal entities; staffing ≥ 6 FTE; cut‑off rules X.
* **Measures:** close in ≤ 5 business days; adjustment error rate < 0.2 %.
* **Context:** `OperatingModel_2025`.
* **Distinction:** This is **ability**; the **Service** “Provide month‑end close” is the external promise derived from this ability once formally offered.


### A.2.2:7 - Bias‑Annotation (as in cluster‑E patterns)

* **Lenses tested:** `Arch`, `Prag`, `Did`, `Epist`.
* **Scope declaration:** Universal; holder constrained to `U.System`.
* **Rationale:** Gives the kernel a clean, reusable **ability concept** so Role (assignment), Method (recipe), Work (execution), and Service (promise) do not collapse into each other. Keeps planning talk truthful and checkable without introducing governance machinery here. **`U.Capability`** is a **dispositional property of a `U.System`** that states its **ability to produce a class of outcomes** (i.e., execute a class of Work) **within a declared `U.WorkScope` (conditions/assumptions) and meeting stated `U.WorkMeasures`**.

### A.2.2:8 - Conformance Checklist (normative)

**CC‑A2.2‑1 (Holder type).**
A capability **belongs to** a **`U.System`** (physical, cyber, socio‑technical, or organizational). Capabilities are **not** assigned to `U.Episteme`.

**CC‑A2.2‑2 (Separation of concerns).**
A capability is **not** a Role, **not** a Method/MethodDescription, **not** a Work, and **not** a Service. Models **SHALL NOT** use capability declarations to stand in for assignments, recipes, executions, or promises.

**CC‑A2.2‑3 (WorkScope required for operational use).**
When a capability is used to qualify a step or to support planning, its statement **MUST** name a **WorkScope** (conditions/assumptions) and **WorkMeasures** (targets/ranges). **Guards that admit Work MUST test** that the **holder’s WorkScope covers the step’s JobSlice** (i.e., `WorkScope ⊇ JobSlice`) **and that WorkMeasures meet the step’s thresholds, with an explicit `Γ_time` window bound**. Without a WorkScope and measures, a capability is advisory and **SHALL NOT** be used for step admission or assurance claims.

**CC‑A2.2‑4 (Context anchor).**
Capability statements that drive operational decisions **MUST** be anchored to a **`U.BoundedContext`** (the “Context” whose vocabulary and test norms apply).

**CC‑A2.2‑5 (QualificationWindow).**
When capabilities are used operationally (e.g., to gate Work), the statement **MUST** carry a **QualificationWindow** (calibration window, software version window, etc.) and the guard **MUST name the `Γ_time` window** used for the check. Outside the QualificationWindow, the claim is not admissible for gating.

**CC‑A2.2‑6 (Past work remains past).**
Updates to a capability statement **SHALL NOT** retroactively invalidate already recorded Work. Past Work is judged against the capability declaration that was valid **at the time of execution**.

**CC‑A2.2‑7 (Threshold checks are orthogonal to roles).**
A step that requires both a Role and a capability threshold admits a Work only if **both** are satisfied: (i) the performer’s **Role assignment** is active in the step window; (ii) the **holder’s capability** meets or exceeds the threshold **with `WorkScope ⊇ JobSlice` and within the **QualificationWindow** at the named **`Γ_time`**.**

**CC‑A2.2‑8 (Derived capabilities).**
If a capability is claimed for a **composite system** (assembled by Γ), the claim **MUST** be stated as a property of that composite holder (not of its parts) with clear dependency notes (e.g., “valid while Subsystem B meets X”). Details of derivation belong to the context’s methodology, not to this definition.

**CC‑A2.2‑9 (No capability for epistemes).**
Algorithms, standards, and documents provide **evidence** or **recipes**; they **do not** “have capability.” Only systems do.

**CC-A2.2-10 (`Γ_time` selector in guards).**
Scope-sensitive guards (including Method–Work gates) **MUST** include an explicit **`Γ_time`** selector indicating the window *W* over which **ScopeCoverage** and **WorkMeasures** are evaluated.

### A.2.2:9 - Capability thresholds on steps (how A.15 uses this concept)

A step in a **Method** may define **required roles** (assignment) and **capability thresholds** (ability). A Work passes the gate if:

1. **assignment check:** the Work’s `performedBy` points to a valid **Role assignment** that covers the step window and satisfies the role relation (including specialization `≤` inside the context).
2. **Ability check:** the **holder** of that Role assignment has a **capability** whose **WorkScope covers the step’s JobSlice** (i.e., declared superset) and whose **WorkMeasures** meet the step’s threshold(s) within `Γ_time(W)` and while the capability’s **QualificationWindow** includes *W*.

**Idioms managers can reuse (plain text):**

* *“S1 requires `IncisionOperatorRole` and Precision ≤ 0.2 mm (OR\_2025 norms) **in window W**.”*
* *“S2 requires `PlannerRole`, **WorkScope ⊇ JobSlice\[W]**, and Optimality ≥ 0.90 on `JS_Schedule_v4`.”*

**What to avoid:**

* Putting “Precision ≤ 0.2 mm” into the Role name. Keep thresholds attached to the **step**; keep **ability** on the **holder**.


### A.2.2:10 - Time and change (calibration, drift, upgrades)

Capabilities are **stable but not static**. Three simple practices keep reasoning honest:

* **Qualification windows.** Abilities drift. Put a **QualificationWindow** on the statement (e.g., “valid for software v4.2; recalibration due 2025-09-30”).
* **Change points.** Note upgrades/downgrades that affect the WorkScope or measures.
* **Snapshot at execution.** When Work is recorded, it is implicitly tied to the **then‑current** capability statement; later edits do not rewrite history (see CC‑A2.2‑6).

**Manager’s rule of thumb:** if you would reschedule a job after a tool change, the capability statement needs a new window.


### A.2.2:11 - Composition and Γ (how assembled systems “can do”)

Γ builds a **new holder** (a composite system). Its capability is not the algebraic sum of parts; it is an **ability of the whole** under its own WorkScope.

* **Express at the whole.** “Cell\_3 can place 12 PCB/min with ±0.1 mm” — that is a capability of **Cell\_3**, not of the pick‑and‑place head alone.
* **State dependencies.** “Valid while Feeder\_A delivers reels at ≥ X; vision subsystem calibrated ≤ 72 h ago.”
* **Constructor vs. transformer.** The **ConstructorRole** builds the composite (Γ); the resulting **TransformerRole** may later act on products. Capability belongs to the holder relevant to the action (builder’s ability vs operator’s ability).


### A.2.2:12 - Interaction with Service (external promise)

A **Service** is an **external promise**. It relies on capability but is not identical to it.

* **From capability to service.** You normally **derive** a Service by taking a capability and **fixing** the promise outward (e.g., “We guarantee close ≤ 5 days”).
* **From service back to capability.** If the promise raises the bar (e.g., tighter SLA), the underlying capability must meet or exceed it under the service’s context.
* **Staffing.** Delivering a Service still requires **Role assignments**; capability alone does not authorize action.

**Memory aid:** Capability = *can do*; Service = *promise to others that we will do*.


### A.2.2:13 - Interaction with Dynamics (laws vs. abilities)

* **Dynamics** describe **how states evolve** (models, laws, trajectories).
* **Capability** says **what this system can achieve** within an WorkScope.
* Dynamics often serve as **evidence** or **explanatory models** for capability but are **not** the capability itself.

**Physics example:** an “isothermal process” (process here as transformation) is a **Work** instance whose path is explained by a **Dynamics** episteme; a lab rig’s ability to run that path repeatably is its **capability**.

### A.2.2:14 - Anti‑patterns (and the right move)

* **Role‑as‑capability.** “Welder role ensures ±0.2 mm.” → Keep **role** as assignment; put **precision** in a **capability** on the holder; put the **threshold** on the **step**.
* **Recipe‑as‑capability.** “We have the ‘Etch\_Al2O3’ capability.” → Recipe is **Method/MethodDescription**; ability is “can execute Etch\_Al2O3 within WorkScope E at measures M.”
* **Work‑as‑capability.** “We did it once, so we can.” → One Work log is not a stable ability; state envelope and measures if you want a capability claim.
* **Context‑less claims.** “This tool can machine titanium.” → Say **where and under what bounds** (context + WorkScope + measures).
* **Stuffing capabilities into BoM/PBS.** Structure lists **what it is**; capabilities belong to **what it can do** (the holder), not inside the parts list.
* **Service‑as‑capability.** “We have the Month‑end Close capability (promise).” → Promise is **Service**; ability is internal, promise is external.


### A.2.2:15 - Migration notes (quick wins for existing texts)

1. **Underline WorkScopes.** For every “can do” sentence, add **conditions** and **measures**; otherwise treat it as background color, not a gate.
2. **Pull thresholds out of roles.** Move “≤ 0.2 mm”, “≥ 0.90 optimality” from role labels into **step requirements**; leave roles clean (assignments).
3. **Pin contexts.** Add the bounded context name to each capability table (“Capability Sheet — AssemblyLine\_2025”).
4. **Snapshot validity.** Add a “valid through” column (software version or calibration horizon).
5. **Separate recipe/execution.** Move flowcharts under **MethodDescription**, runs under **Work**; link the capability to the **holder** with references to those specs.


### A.2.2:16 - Consequences

| Benefits                                                                                           | Trade‑offs / mitigations                                                                                                      |
| -------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- |
| **Truthful planning.** Schedulers and managers can ask “can do?” independently of “assigned now?” | **Extra column in tables.** Adding scope/measures/valid‑through is a small burden that repays itself in fewer reschedules. |
| **Safer gating.** Steps gate on both role and ability; fewer silent failures.                      | **Two checks instead of one.** Keep the checklist simple: *badge + bounds*.                                                   |
| **Clear service design.** Services become explicit promises built on visible abilities.            | **Temptation to over‑promise.** Keep service SLOs within demonstrated capability measures.                                    |
| **Clean separation with Dynamics and PBS/SBS.** No more “process” or “function” soup.              | **Some retraining.** Use the litmus tables (from the lexical rules) during onboarding.                                        |


### A.2.2:17 - Relations

* **Builds on:** A.1 Holonic Foundation; A.1.1 `U.BoundedContext`; A.2 Role; A.2.1 `U.RoleAssignment`.
* **Coordinates with:** A.3 (Transformation & role masks); A.15 (Role–Method–Work Alignment).
* **Constrains:** Step design: thresholds belong on steps; BoM/PBS must stay structural.
* **Informs:** `U.ServiceClause` definitional pattern (external promises derive from capabilities); `U.Dynamics` definitional pattern (models used as evidence or predictors); Γ/aggregation (capability of composites is stated at the whole).
* **Lexical guards:** E.10.x **L‑FUNC** (do not call capability “function”); E.10.y **L‑PROC** (do not call capability “process”).


### A.2.2:18 - Didactic quick cards (reuse in specs and slides)

* **Capability = can do (within bounds).** assignment ≠ ability ≠ recipe ≠ execution ≠ promise.
* **Gate every critical step with two checks:** *badge (Role assignment)* + *bounds (Capability)*.
* **Write the Context on every claim:** context name, **WorkScope**, measures, **QualificationWindow/valid-through**.

### A.2.2:End

## A.2.3 - `U.ServiceClause` (Service Clause)

### A.2.3:1 - Context

Across domains the word **service** is used for many different things: a server or **provider**, an **API**, a **procedure**, a **run**, a **department**, even a **product bundle**. Such polysemy is productive in everyday speech but toxic in a normative model.

FPF therefore reserves **`U.ServiceClause`** for exactly one kernel meaning: **promise content** — a **service clause** (a consumer‑facing promise statement). Any other “service” sense MUST be modeled explicitly as `U.System`, `U.RoleAssignment`/principal, `U.MethodDescription`, or `U.Work` inside an appropriate `U.BoundedContext` and, in normative prose, MUST be written with an explicit **facet head phrase** per **A.6.8 (RPR‑SERV)**.

**Legacy alias (compatibility).** `U.Service` is a deprecated alias for `U.ServiceClause`. It MAY appear in pre‑refactor material, but conforming new normative text and machine‑checkable artefacts SHALL use `U.ServiceClause`.

This keeps the kernel minimal while keeping the prose readable to non‑mathematicians: the canonical symbol is `U.ServiceClause` (legacy alias: `U.Service`), and the head kind in normative text is always *service clause*.

**Modularity note.** A.2.3 defines only the promise‑content object (the **service clause**) and its direct links to roles, access specification, acceptance criteria, and work evidence. The multi‑facet “service situation” bundle that also names provider principals/systems/access points/commitments/acts is handled as a precision‑restoration lens in **A.6.8 (`serviceSituation(…)`)**. Contract‑talk unpacking (and routing of “contract / SLA / guarantee” language) is handled by **A.6.C**, which calls A.6.8 when service‑cluster tokens appear.

In the Role–Method–Work alignment, the **service clause** must say something **external‑facing** and **consumer‑oriented**, yet remain separate from *how* the provider does it (Method/MethodDescription) and *what actually happened* (Work).

> Intuition: a **service** is the promise you advertise and are judged by; **work** is what you do to keep that promise; **method/spec** is how you know what to do.
> (Normative head-kind rewrite): a **service clause** is the promise clause you advertise and are judged by; **work** is what you do (and what can be evidenced) to satisfy that promise; **method/spec** is how you know what to do.

**Lexical note (L‑SERV / RPR‑SERV)**

The surface forms *service/service‑level/service use/service access* (and the adjacent cluster *service provider*, *server*) are **ambiguous** across domains. In the kernel, **`U.ServiceClause`** (legacy alias: `U.Service`) is reserved for promise content only and is written in prose as a **service clause**.

Normative prose therefore SHALL treat the bare head noun **service** as **always‑unpack** (PTG=Guarded): every head‑noun occurrence MUST be rewritten to a facet head phrase (service clause / service provider principal / service access point / service delivery system / …) or to the correct underlying FPF object (team, ticket, endpoint host, procedure, work item), per **A.6.8 (RPR‑SERV)**.

E.10’s lexical anchor **L‑SERV** SHOULD be implemented as “pointer + lint rule” to A.6.8: the short rule names the hazard, while A.6.8 provides the full rewrite recipe and the facet head phrase set.


### A.2.3:2 - Problem

Without a first‑class `U.ServiceClause`, models drift into five recurring errors:

1. **Provider = Service.** Calling the **system** or **team** “the service” collapses structure with promise.
2. **API = Service.** Treating an **interface/endpoint** as the service hides the consumer‑oriented promise (effect + acceptance).
3. **Process = Service.** Mapping a **procedure/Method** (or a WorkPlan) to “service” confuses recipe/schedule with the external commitment.
4. **Run = Service.** Logging **Work** as “a service” erases the Standard/promise layer and breaks SLA reasoning.
5. **Business ontology lock‑in.** Large domain schemes (e.g., “business service” stacks) are imported wholesale, losing FPF’s universality and comparability across contexts.


### A.2.3:3 - Forces

| Force                                       | Tension                                                                                                       |
| ------------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
| **External promise vs internal capability** | Service must be consumer‑facing, while capability is provider‑internal.                                       |
| **Specification vs execution**              | Service is a **specifiable** obligation; value is **realised** only by runs of Work.                          |
| **Universality vs domain richness**         | One kernel meaning must cover IT, utilities, healthcare, public services—without absorbing domain taxonomies. |
| **Measurability vs privacy**                | Consumers need SLO/SLA and outcomes; providers want implementation freedom (Method autonomy).                 |
| **Stability vs evolution**                  | Services version and change without invalidating prior Work evidence.                                         |


### A.2.3:4 - Solution — The unified concept `U.ServiceClause`

**Definition (normative).**
Within a `U.BoundedContext`, a **`U.ServiceClause`** is an **externally oriented promise clause**: a context‑local statement of (i) a **promised external effect**, (ii) **eligibility + access** (how a consumer may request/use), and (iii) **acceptance criteria** (SLO/SLA‑like targets) by which fulfillment is judged.

`U.ServiceClause` is **promise content** (`U.Episteme`), not a deontic binding. One or more explicit **`U.Commitment`** objects (A.2.8) MAY reference a `U.ServiceClause` as payload to bind an accountable principal/role‑assignment; the clause itself does not “obligate” anyone until such a commitment is represented.

In normative prose, the head phrase for `U.ServiceClause` is **service clause** (or **service promise clause**) per A.6.8; the bare noun *service* is not a valid shorthand for this kernel object.

* **Type:** `U.Episteme` (a promise clause on a carrier).
* **Scope:** design‑time concept; judged at run‑time by evidence from `U.Work`.
* **Time stance:** design-time concept; judged at run-time by evidence from `U.Work`.
* **Orientation:** consumer‑facing (“what you can rely on”), as opposed to capability (“what we can do”).
* **Prose head (normative):** *service clause* (Tech) / *service promise clause* (Plain). (Both twins retain an explicit **clause** head‑kind to avoid act/content ambiguity and to comply with A.6.8 headword governance.)

#### A.2.3:4.1 - Core structure (minimal fields)

```
U.ServiceClause {
  context        : U.BoundedContext,   // where the promise is meaningful
  purpose        : Text/Episteme,      // the externally observable effect/value
  providerRole   : U.Role,             // role kind that may provide it (not a person/system)
  consumerRole?  : U.Role,             // optional role kind allowed to consume
  claimScope?    : U.ClaimScope,       // where the promise holds (G) — operating conditions/populations/locales
  accessSpec?    : U.MethodDescription,       // service access spec: request-facing interface/eligibility; not an access point system
  acceptanceSpec : U.Episteme,         // targets: SLO/SLA, quality/throughput/latency/accuracy…
  unitOfDelivery?: Episteme,           // how delivered units are counted/measured
  version?       : SemVer/Text,
  timespan?      : Interval
}
```

* `providerRole` and `consumerRole` are **role kinds**; the actual performers are **RoleAssignments** at run‑time.
* `acceptanceSpec` defines **what counts as fulfilled** (the test).
* `accessSpec` is **how to ask** (eligibility, protocol, counter, desk, API).
* **Internal delivery methods/runbooks are not part of the service clause.** Model them as `U.MethodDescription` and relate them to the clause via `serviceSituation(…)` (A.6.8) or explicit context relations; providers retain **Method autonomy**.

#### A.2.3:4.2 - What `U.ServiceClause` is **not**

* **Not a provider:** use `System#ServiceProviderRole:Context` `U.RoleAssignment`.
* **Not a deontic commitment:** that is `U.Commitment` (A.2.8) referencing the service clause as payload.
* **Not an access point:** addressable “services/servers/desks/endpoints” are `U.System` (see A.6.8: *service access point* / *service delivery system*).
* **Not a method/recipe:** that is `U.Method/MethodDescription`.
* **Not a run/incident/ticket:** that is `U.Work`.
* **Not a schedule:** that is `U.WorkPlan`.
* **Not a capability:** capability is **provider‑intrinsic ability**; service is **outward promise**. A service may **require** certain capabilities, but it **is not** the capability.
* **Not a scope label:** do **not** use *applicability*, *envelope*, *generality*, or *validity* as **scope characteristics**; declare **Claim scope (G)** or **Work scope** explicitly where needed (A.2.6).

#### A.2.3:4.3 - Position in the enactment chain

* **Design‑time:**
  The context **declares Claim scope (G)** for acceptance (operating conditions, populations, locales) per A.2.6.
  The context may assert: `bindsCapability(ServiceProviderRole, Capability)`.
  Providers choose `Method/MethodDescription` to realise the promised effect described by the service clause.

* **Run‑time:**
  A **consumer** performs `Work` (e.g., a request/visit) — `performedBy: ConsumerRoleAssigning`.
  The **provider** performs `Work` to fulfil the service clause — `performedBy: ProviderRoleAssigning`.
  Delivered `Work` instances are evaluated against `acceptanceSpec` and **counted** via `unitOfDelivery`.
  SLA/SLO outcomes are therefore functions over **Work evidence**, not over the service clause object itself.
 
  (Terminology note: use `…RoleAssignment` consistently for the run‑time enactor relation; avoid the “RoleAssigning” variant unless it is a separately defined kind in the Context.)

> **Memory hook:** *Service clause promises, Method describes, Work proves.*

#### A.2.3:4.4 - Didactic card: The service delivery chain (clause → commitment → situation → work → acceptance)

> **Didactic (non‑normative).** This is a one‑screen “map” that stitches the modular pieces together:
> `U.ServiceClause` (A.2.3) → `U.Commitment` (A.2.8) → provider `U.RoleAssignment` (A.2.1) → *serviceSituation(...)* facet slots (A.6.8 lens) → `U.Work + carriers` (A.15) → acceptance verdict (A.2.3).
>  
> This is **not new ontology**. It is a reader‑safety diagram that prevents two common category errors:
> (i) treating `U.ServiceClause` as something addressable (“the service you call”), and
> (ii) treating `serviceSituation(...)` as semantics rather than a *binding lens* over already‑defined kinds.

**Reading guide (one breath).**
* The **service clause** is *what is promised* (promise content).
* The **commitment** is *who is bound* (deontic accountability) and it **references** the clause.
* The **provider role assignment** is the accountable subject *that can act* in a given Context/window.
* `serviceSituation(...)` (A.6.8) is a **facet‑binding lens** that names the common “service talk” participants (access spec / access point / delivery system / delivery method) **without** collapsing them into the clause.
* **Work + evidence** is what happened; the **acceptance verdict** is computed by applying the clause’s `acceptanceSpec` to work evidence (not by reading the clause, and not by “looking at the service” as a system).

**Litmus rule (addressability).**
If you can *call / connect to / visit / restart / scale* it, you are talking about a **service access point** (system facet), not the **service clause** (promise content).


### A.2.3:5 - Archetypal grounding (engineer‑manager friendly)

| Domain                    | **`U.ServiceClause` (promise)**                           | Provider & Consumer (as Roles)                                   | Access (how to ask)                  | Fulfilment (Work)                        | Typical acceptance targets                  |
| ------------------------- | --------------------------------------------------------- | ---------------------------------------------------------------- | ------------------------------------ | ---------------------------------------- | ------------------------------------------- |
| **Cloud/IT**              | “**Object Storage**: durable PUT/GET of blobs up to 5 TB” | `CloudTeam#ServiceProviderRole`, `BackupJob#ServiceConsumerRole` | `S3_API_Spec_vX` (`MethodDescription`)      | Each PUT/GET run; data durability checks | Availability ≥ 99.9%, durability 11×9       |
| **Manufacturing Utility** | “**Compressed air** at 8 bar in Zone B”                   | `Maintenance#Provider`, `LineB#Consumer`                         | Manifold access rules (`AccessSpec`) | Compressor cycles & delivery logs        | Pressure window, purity class, flow ceiling |
| **Public Service**        | “**Passport issuance** within 20 days”                    | `Agency#Issuer`, `Citizen#Applicant`                             | Portal/desk SOP (`AccessSpec`)       | Case handling runs                       | Lead time ≤ 20 days, defect ≤ 1%            |

**Key takeaway:** the **same kernel object** models S3, a plant utility, and a government service: a **promise with access and acceptance**. Everything else (APIs, compressors, clerks, workflows, tickets) is mapped via **Role/Method/Work**.


### A.2.3:6 - Mapping the common “service” picture to FPF (didactic bridge)

The popular service diagrams (provider ↔ access ↔ use ↔ capability/activity) map to FPF as follows:

* **Agent (as Service Provider)** → `System#ServiceProviderRole:Context` (`U.RoleAssignment`).
* **Service Agreement / SLA** → `U.ServiceClause.acceptanceSpec` (+ optional `WorkPlan` for windows).
* **Operating conditions / “where the promise holds”** → `claimScope : U.ClaimScope (G)` (or embedded in `acceptanceSpec`) per A.2.6.
* **Service Presence / Access** → `accessSpec : MethodDescription` (interface/eligibility); actual endpoints are **systems** playing interface roles.
* **Individual Service Use** → **consumer and provider `U.Work`** instances linked to the `U.ServiceClause` they fulfil.
* **Service‑Enabled Capability / Activity** → effects on the consumer side: either a **Capability** gained/used, or **Work** performed; do **not** reify as a new kernel type.

(Where a domain needs richer structures—catalogs, exposure layers, charging, entitlement—model them **in the domain context** and relate them to `U.ServiceClause` via `U.RoleAssignment` and alignment bridges.)

### A.2.3:7 - Conformance Checklist (normative)

**CC‑A2.3‑0 (Prose head phrase).**
In normative prose, an instance of `U.ServiceClause` (legacy alias: `U.Service`) SHALL be referred to as a **service clause** (or **service promise clause**) and SHALL NOT be referenced by the bare head noun *service*. Unqualified *service* usage (and the co‑moving cluster *service provider* / *server*) SHALL be unpacked per A.6.8 (RPR‑SERV).

**CC‑A2.3‑1 (Type).**
`U.ServiceClause` **IS** an `U.Episteme` (a consumer‑facing **service clause** on a carrier). It is **not** a `U.System`, **not** a `U.Method/MethodDescription`, **not** a `U.Work`, and **not** a `U.WorkPlan`.

**CC‑A2.3‑2 (Context).**
Every **service clause** **MUST** be declared **inside** a `U.BoundedContext`. Names and meaning are **local**; cross‑context reuse requires a Bridge (`U.Alignment`).

**CC‑A2.3‑3 (Role kinds, not people/systems).**
`providerRole` and (if used) `consumerRole` **MUST** be **role kinds** (see A.2). Actual performers at run‑time are `U.RoleAssignment`s.

**CC-A2.3-4 (Acceptance).**
`acceptanceSpec` **MUST** be present and **MUST** define how delivered `U.Work` is judged (pass/fail/graded) against declared targets (SLO/SLA-like), and **MUST** declare **Claim scope (G)** where relevant (operating conditions, populations, locales). Every verdict binds to an explicit **Γ_time** window.

**CC‑A2.3‑5 (Access).**
If consumers must request/obtain the service through an interface, `accessSpec` **MUST** reference the MethodDescription that defines eligibility and invocation rules (API/desk/SOP). If the service is ambient (e.g., compressed air on a manifold), accessSpec **MAY** be omitted, but the eligibility condition **MUST** be stated in the context.

**CC‑A2.3‑6 (Unit of delivery).**
If performance is counted/charged, `unitOfDelivery` **SHOULD** be declared (e.g., “request”, “kWh”, “case”).

**CC‑A2.3‑7 (No actuals on Service).**
Resource/time **actuals** and incident logs **MUST** attach to `U.Work` only (A.15.1). Services carry no actuals.

**CC‑A2.3‑8 (Capability requirement).**
If the context requires provider abilities, it **MUST** express them as `bindsCapability(providerRole, Capability)` in the context, not by stuffing capabilities into the Service object.

**CC‑A2.3‑9 (Versioning & timespan).**
Service clauses **MAY** carry `version`/`timespan`. A `U.Work` that claims/fulfils a service clause **MUST** record which service‑clause version it used.

**CC‑A2.3‑10 (Lexical rule).**
Unqualified head‑noun uses of *service* (and the co‑moving cluster *service provider* / *server*) in normative prose **MUST** be disambiguated per **A.6.8 (RPR‑SERV)** and its lexical anchor **L‑SERV** (E.10). When the intended referent is `U.Service`, the head phrase SHALL be **service clause**.

**CC‑A2.3‑11 (No mereology).**
Do **not** place a Service in PBS/SBS or treat it as a part/component. Structural assemblies live in PBS/SBS; Service is a promise.

**CC‑A2.3‑12 (Plan–run split).**
Windows and calendars belong to `U.WorkPlan` (A.15.2). Fulfilment evidence belongs to `U.Work` (A.15.1).

**CC-A2.3-13 (Scope lexicon & guards).**
Deprecated labels *applicability/envelope/generality/validity* **MUST NOT** appear as scope characteristics in guards or conformance blocks. Use **`U.ClaimScope (G)`** for epistemes and **`U.WorkScope`** for capabilities (A.2.6/A.2.2). Scope-sensitive guards **MUST** use **ScopeCoverage** with explicit **Γ_time** selectors.

**CC-A2.3-14 (Bridges & CL).**
Cross-context mappings via Bridges keep **F/G** stable; **CL** penalties apply to **R**. A mapping **MAY** recommend **narrowing** the mapped **Claim scope (G)** as best practice (A.2.6/B-line).

### A.2.3:8 - Evidence relations & operators (Service ⇄ Work)

To keep the promise → evidence path explicit:

#### A.2.3:8.1 - Core relations

* **`claimsServiceClause(Work, ServiceClause)`** — the Work instance **intends** to fulfil the service clause (pre‑verdict).
* **`fulfilsServiceClause(Work, ServiceClause)`** — the Work instance **meets** the service clause’s `acceptanceSpec` (post‑verdict: pass).
* **`acceptanceVerdict(Work)`** → {`pass`, `fail`, `partial`, context‑specific grades} — computed by applying `acceptanceSpec` to Work facts.
* **`usesAccess(Work, MethodDescription)`** — consumer Work that invokes the service via its `accessSpec` (when applicable).

> **Invariant:** `fulfilsServiceClause(W,SC)` ⇒ `claimsServiceClause(W,SC)` and `acceptanceVerdict(W)=pass`.
> **Invariant:** A Work can claim/fulfil **multiple** service clauses only if the context declares a counting policy (no silent double‑counting).

#### A.2.3:8.2 - Service‑clause performance operators

Let `W(SC, T)` be the set of Work that `claimsServiceClause(-,SC)` within time window `T`. Let `W✓(SC, T)` be those with `fulfilsServiceClause`.

* **Delivered units:** `delivered(SC, T) = |W✓(SC, T)|` (or sum per `unitOfDelivery`).
* **Rejection rate:** `rejectRate(SC, T) = 1 − |W✓(SC,T)| / |W(SC,T)|` (declare handling of `partial`).
* **Lead time:** average/percentile of `duration(Work)` or of request→completion delta (declare definition).
* **Availability/Uptime:** computed from Work/telemetry events per the context’s definition (declare availability source).
* **Cost‑to‑serve:** sum of `Γ_work` over `W✓` per resource category (A.15.1).

All metrics are **functions of Work evidence**; the service clause object is never the bearer of actuals.
Aggregation across time uses `Γ_time` policies (union vs convex hull) chosen by the KPI owner.


### A.2.3:9 - Anti‑patterns (and the right move)

* **“The microservice **is** the service.”**
  Rewrite to facet‑explicit terms (A.6.8): the microservice is typically a **service delivery system** (`U.System`) and/or a **service access point** (`U.System`). Keep the **promise content** as a **service clause** in `U.ServiceClause` (legacy alias: `U.Service`), and bind accountability via `U.Commitment` if needed.

* **“The API **is** the service.”**
  The API is typically a **service access spec** (`accessSpec : MethodDescription`) (and systems playing interface roles). The **service clause** is the promise content judged by `acceptanceSpec`.

* **“Our **process** is the service.”**
  Process/recipe is `U.Method/MethodDescription`; schedule is `U.WorkPlan`. The **service clause** is **what is promised to the consumer**.

* **“The **ticket** is the service.”**
  A ticket/case is `U.Work` (and perhaps a `WorkPlan` item). Evidence and outcomes sit on Work, not on the service clause.

* **“Attach cost to the service.”**
  Actual cost/time attach to `U.Work` only (A.15.1). Service metrics are computed **from** Work.

* **“Put service under BoM.”**
  Services are not structural parts. Keep PBS/SBS clean.

* **“Hard‑code people into the service.”**
  Name **role kinds** in the service clause (`U.Service`); run‑time performers are `U.RoleAssignment`s.


### A.2.3:10 - Migration notes (quick wins)

1. **Name the promises.** List 5–15 consumer‑facing promises your context lives by; reify each as `U.ServiceClause` with `acceptanceSpec` and, if needed, `accessSpec` and `unitOfDelivery`.
2. **Separate provider from service clause.** Keep systems/teams as `U.System`; make them providers via `…#ServiceProviderRole:Context`.
3. **Wire evidence.** Ensure every relevant `U.Work` has `claimsServiceClause` (and `fulfilsServiceClause` post‑verdict).
4. **Choose metrics.** For each Service, define 2–4 KPIs and the **exact** Work-based formulas (availability, lead-time, rejection rate, cost-to-serve), and declare the **Claim scope (G)** and **Γ_time** policy used for each KPI.
   → For each **service clause**, define 2–4 KPIs and the exact Work-based formulas, with explicit `Γ_time`.
5. **Bridge domains.** If a business ontology already exists (“business/technical/internal service”), keep it in its own context and map to `U.Service` via Bridges.
6. **Tidy language.** Apply **A.6.8 (RPR‑SERV)** / **L‑SERV**: ban unqualified “service” as a synonym for server/team/process/ticket in normative prose; map them explicitly.


### A.2.3:11 - Relations

* **Builds on:** A.1.1 `U.BoundedContext`; A.2 `U.Role`; A.2.1 `U.RoleAssignment`; A.2.2 `U.Capability`; **A.2.6 `U.Scope` / `U.ClaimScope (G)` / `U.WorkScope`**.
* **Coordinates with:** A.3.1 `U.Method`; A.3.2 `U.MethodDescription`; A.15.1 `U.Work`; A.15.2 `U.WorkPlan`; **A.6.8 (RPR‑SERV)** for normative prose unpacking of the service cluster; **B-line Bridges & CL (CL→R; may recommend ΔG narrowing)**.
* **Constrained by lexical rules:** **E.10 L‑SERV** (service disambiguation); also **L‑FUNC**, **L‑PROC**, **L‑SCHED**, **L‑ACT**.
* **Informs:** Reporting/assurance patterns (service KPIs, SLA dashboards); catalog/exposure patterns in domain contexts.


### A.2.3:12 - Didactic quick cards (engineer‑manager ready)

* **Service clause = Promise content.** *What we advertise and are judged by.*
* **Method/Spec = Recipe.** *How we usually do it (provider‑internal).*
* **Work = Evidence.** *What actually happened and consumed resources.*
* **Provider/Consumer = Roles.** *assignment via RoleAssigning at run‑time.*
* **Metrics from Work.** *Uptime, lead time, quality are computed from Work, not from the Service object.*
* **Keep PBS/SBS clean.** *Services are not parts; they are promises.*
  
### A.2.3:End

## A.2.4 - `U.EvidenceRole`

> *This pattern defines how a knowledge artefact (“episteme”) serves as **evidence** for a specific claim or theory **inside a bounded context**. It is a **non-behavioural** role enacted via `U.RoleAssignment`; the evidence-role assignment **must** declare the **target claim**, the **claim-scope**, and a **timespan of relevance**. Evidence is a classificatory status of an episteme; it is not an action and it is not an assignment of an actor.*

### A.2.4:1 - Context and intent

FPF separates **what exists** (holons and their kinds) from **what acts** (systems under roles performing work) and from **what is known** (epistemes carried on symbols). Roles are contextual masks that holons may wear; role meanings are **local to a `U.BoundedContext`**. In this setting, we need a kernel‑level way to say that *this* episteme **counts as evidence** about *that* claim, **here**, and **for this period**, without confusing evidence with services, methods, or work. 

**Intent.** Provide one uniform, discipline‑neutral role by which an episteme can be assigned as evidence, while keeping:

* **Agency** on systems performing `U.Work` (not on epistemes).
* **Promise** and Standardual language on `U.ServiceClause` (not on evidence).
* **Recipe** and eligibility on `U.Method` / `U.MethodDescription` (not on evidence).

### A.2.4:2 - Problem

1. **Anthropomorphising epistemes.** Models say “the paper proves…”, implicitly treating a document as an actor.
2. **Citation without scope.** Links exist but lack explicit **target claim**, **applicability scope**, and **time window**.
3. **Deductive versus empirical conflation.** A formal derivation and a lab dataset are both called “support” although their semantics and ageing differ.
4. **Staleness and drift.** Empirical evidence ages; without explicit validity windows, stale evidence keeps influencing conclusions.
5. **Cross‑context leakage.** Evidence is interpreted as “global,” skipping the bridge that is required to move meaning across contexts.

### A.2.4:3 - Forces

| Force                                     | Tension to resolve                                                                                |
| ----------------------------------------- | ------------------------------------------------------------------------------------------------- |
| **Universality versus domain practice**   | One role must cover proofs, datasets, replications, benchmarks, model fits, calibrations.         |
| **Static truth versus ageing confidence** | Axiomatic proofs are stable relative to a theory; empirical evidence decays and requires refresh. |
| **Local meaning versus reuse**            | Meaning is context‑local; reuse must pass through explicit bridges, not tacit “global truth.”     |
| **Clarity versus brevity**                | Kernel must stay expressive without importing domain governance or tooling procedures.            |

### A.2.4:4 - Solution — Term and definition

**Term.**
`U.EvidenceRole` — a **non-behavioural role** that a `U.Episteme` may play **inside a `U.BoundedContext`** to serve as **evidence** for a declared target claim (or theory/version).
The target claim, its applicability scope, polarity, weighting model, and other normative facets are **properties of the `U.EvidenceRole` definition itself** *within that bounded context*.

**How it is enacted.**
The role is enacted by a standard `U.RoleAssignment` that connects:

```
RoleAssigning {
  holder  : U.Episteme,        // the artefact: paper, proof, dataset, report…
  role    : U.EvidenceRole,    // a context-defined role with normative properties
  context : U.BoundedContext   // where the role definition is valid
  timespan?: Interval          // optional: relevance window for this specific assignment
}
```

The **normative properties** of the role (e.g., `claimRef`, `claimScope`, `polarity`, `weightModelRef`) are set in the **role’s definition** in the given `U.BoundedContext`, not in the evidence-role assignment.
`U.RoleAssignment` carries only the linkage between a concrete episteme and a role already defined and attributed in that context.

> **Non-behavioural guard.** The holder is an episteme; any actions that produced it are `U.Work` performed by systems. Evidence classifies an artefact’s evidential status; it does not itself enact behaviour.

**Minimal readable grammar (informative).**
`<Episteme>#<EvidenceRole>:<Context>` — where `<EvidenceRole>` in `<Context>` already normatively specifies `polarity Claim / Scope [weight]`.

**Examples.**

* In `Cardio_2026`, `ModelFitEvidenceRole` is defined with:
  `claim = β-blocker > placebo`, `claimScope = adults 40–65`, `polarity = supports`, `weightModelRef = KD:SupportMeasure`.
  Binding:
  `Trial-R3.csv#ModelFitEvidenceRole:Cardio_2026`.

* In `Theory_T`, `AxiomaticProofRole` is defined with:
  `claim = Theorem-12`, `claimScope = all x ∈ D`, `polarity = supports`.
  Binding:
  `Lemma-12.proof#AxiomaticProofRole:Theory_T`.


### A.2.4:5 - Role family and specialisations

`U.EvidenceRole` is a **role kind** refined by **specialisation** (no mereology of roles). The recommended, substrate‑neutral specialisations are:

**5.1 Axiomatic line (deductive inside a fixed theory)**

* **`AxiomaticProofRole`** — a proof that **entails** a target statement in a declared `U.TheoryVersion`.
* **`CounterexampleRole`** — a witness that **refutes** a universally quantified claim in the theory.
* **`DerivationRole`** — a lemma or intermediary derivation establishing a dependency in the proof spine.
* **`EquiconsistencyEvidenceRole`** — a metaproof establishing equiconsistency or relative strength, often used to **constrain** theory choice.

**Semantics.** In a fixed theory version, these roles are **boolean** and **non‑decaying**. If the axiom base or definitions change, the binding must be re‑issued for the new version; there is no silent carry‑over.

**5.2 Experimental line (empirical, inductive, and model‑selection)**

* **`ObservationEvidenceRole`** — raw or processed observations under a declared method.
* **`MeasurementEvidenceRole`** — calibrated measurements with an error model and traceability.
* **`ModelFitEvidenceRole`** — comparative fit or likelihood of data to competing models; supports one **over** another within the declared scope.
* **`ReplicationEvidenceRole`** — independent replication status (full, partial, failed).
* **`CalibrationEvidenceRole`** — evidence about the measurement chain (instrument validity), typically **constraining** claims.
* **`BenchmarkEvidenceRole`** — standardised tasks or suites producing comparable scores.

**Semantics.** Experimental roles require a **claim‑scope** and a **relevance timespan**. Their contribution to confidence is **graded** and may **decay**; the same artefact may carry multiple bindings for different claims or scopes (distinct role assignments).

> **Specialisation, not stacking.** Do not build chains like “transformer‑agent‑observer role.” A system enacts behavioural roles (e.g., `TransformerRole`) to **perform work**; an episteme enacts `U.EvidenceRole` to **classify** its evidential function. Keep enactment lines separate.

### A.2.4:6 - Clear distinctions (Strict Distinction, litmus tests)

| If you are talking about…               | Use in FPF                                                    | Why                                                                   |
| --------------------------------------- | ------------------------------------------------------------- | --------------------------------------------------------------------- |
| **Who acted and consumed resources**    | `U.System` with `U.RoleAssignment` performing `U.Work`           | Only systems act; work records resource deltas.                       |
| **What was promised to a consumer**     | `U.ServiceClause` (promise with access and acceptance)              | A promise is not evidence; it is judged from work.                    |
| **How work should be done or invoked**  | `U.Method` / `U.MethodDescription`                                   | Recipes and interfaces are not evidence.                              |
| **What counts as evidence for a claim** | `U.Episteme` holding `U.EvidenceRole` via `U.RoleAssignment`     | Evidence is a status of an artefact relative to a claim in a context. |
| **Moving meaning across contexts**      | An explicit bridge/alignment pattern in the receiving context | Role meanings are context‑local by design.                            |

### A.2.4:7 - Core invariants (concept level)

1. **Holder type.** `U.EvidenceRole` is held by a **`U.Episteme`** only; never by a system, work, method, or service.  # [M‑0]
2. **Context anchor.** Every evidence-role assignment **must** name a `U.BoundedContext`; meaning is local and does not propagate implicitly.
3. **Target claim.** Every evidence-role assignment **must** reference a resolvable claim or theory statement and declare **polarity** `{supports | refutes | constrains | neutral}`.
4. **Claim-scope.** Every evidence-role assignment **must** declare an applicability scope; for the axiomatic line this can be the theory’s domain.
5. **Timespan.** Every evidence-role assignment **must** declare a relevance interval. Axiomatic roles may be open-ended **for a fixed theory version**; experimental roles require finite or refreshable windows.  **Gating:** narrative only at **M-0**; explicit `timespan` & `decayClass` at **M-2**; version fence & `proofChecks` at **F-**.  # [M/F]
6. **Non-self-evidence.** The provenance of experimental evidence-role assignments **must** trace to external `U.Work` performed by systems under roles; an episteme cannot “evidence itself.”
7. **No mixing of stances.** Do not mix design‑time proof artefacts and run‑time traces in one provenance chain; relate them via separate bindings if needed.
8. **No role mereology.** Roles have **no parts**; refine by **specialisation** only. This prevents confusing “sub‑role” with “subsystem”.   **Profile note:** The constraint is universal (applies to **all profiles**).  # [all]

**Minimal readable grammar (informative).**  
`<Episteme>#<EvidenceRole>:<Context>` — where `<EvidenceRole>` is **defined inside `<Context>`** with normative facets (`claimRef`, `claimScope`, `polarity`, optional `weightModelRef`, decay policy).

**Examples (illustrative only):**

*Cardio (empirical line)*  
Role **definition** in `Cardio_2026`:  
`ModelFitEvidenceRole` with  
`claimRef = (β-blocker > placebo)`, `claimScope = adults 40–65`, `polarity = supports`, `weightModelRef = KD:SupportMeasure`.  
**Binding:**  
`Trial-R3.csv#ModelFitEvidenceRole:Cardio_2026`

*Graph theory (formal line)*  
Role **definition** in `GraphTheory`:  
`AxiomaticProofRole` with `claimRef = Theorem-12`, `claimScope = all finite DAG`, `polarity = supports` (entails), fenced to `TheoryVersion = 3.1`.  
**Binding:**  
`Lemma-12.proof#AxiomaticProofRole:GraphTheory`

### A.2.4:8 - Facets and semantics (normative)

This section deepens the definition of `U.EvidenceRole` by specifying **which normative facets** are attached to its definition within a `U.BoundedContext`, **how decay is handled**, **what provenance anchors are required**, and **how the role contributes to assurance computation**.

#### A.2.4:8.1 - Claim-scope schema

Every `U.EvidenceRole` definition **within a `U.BoundedContext`** **MUST** declare a claim-scope record. This record ties the role’s meaning to the exact target claim and its claim scope, and aligns with the typed-claim form used in B.3:

| Field           | Meaning                            | Norms                                                                                               |
| --------------- | ---------------------------------- | --------------------------------------------------------------------------------------------------- |
| `claimRef`      | Identifier of the supported claim  | MUST resolve within the context’s claim graph; dangling IDs forbidden.                              |
| `claimHost`     | The holon whose claim is supported | MAY be `U.System` or `U.Episteme`.                                                                  |
| `epistemicMode` | `formal` or `postulative`          | MUST be present; governs stability and decay rules.                                                 |
| `assuranceUse`  | `TA` / `VA` / `LA`                 | Declares whether the evidence functions as typing, verification, or validation input (B.3.3).       |
| `applicability` | Domain subset (envelope)           | Optional for formal proofs; REQUIRED for empirical evidence (units, constraints, parameter ranges). |
| `resultKind`    | Kind of content on the carrier     | Examples: theorem/proof obligation; dataset; calibration; model-fit result.                         |
| `notes`         | Additional context                 | Pointers to SCR/RSCR entries; congruence rationale; bridge IDs if imported from another context.    |

#### A.2.4:8.2 - Timespan and decay

Evidence is perishable unless proven otherwise.

* **Formal (axiomatic) roles** MAY have open-ended `timespan.to = null` **only** if fenced to a specific `U.TheoryVersion` and justified in `notes`.
* **Empirical roles** MUST have a finite or refreshable `timespan`. Decay parameters (half-life, renewal window) are set by the context policy and referenced in the role definition.

When the relevance window closes (`validUntil` reached), the evidence incurs **Epistemic Debt (ED)**. Per B.3.4, debt must trigger one of three managed actions:

1. **Refresh** — new work produces fresh evidence for the same claim and scope.
2. **Deprecate** — role is retired; claim support is reduced or removed.
3. **Waive** — explicit steward decision to accept the stale evidence temporarily.

#### A.2.4:8.3 - Provenance hooks

Each `U.EvidenceRole` **MUST** anchor into the **Evidence–Provenance DAG** (A.10):

* **Formal**: `verifiedBy` → proof artefact carrier(s), with optional `checkedBy` metadata for proof-checker runs.
* **Empirical**: `validatedBy` → data carriers from observed `U.Work` runs; `protocolRef` → `U.MethodDescription`; `fromWorkSet` → IDs of those runs.
* SCR/RSCR anchors (A.10) are mandatory for all carriers.

**No self-evidence rule**: the producing `U.Work` must have been performed by a system in an **external** role; an episteme cannot “prove itself” without independent generation.

#### A.2.4:8.4 - Contribution to assurance

A `U.EvidenceRole` classifies an artefact; its contribution to the target claim’s assurance tuple ⟨F, G, R⟩ is computed in B.3 using:

* **F (formality)** — lower-bounded by the least formal constituent in the provenance path.
* **G (ClaimScope)** — limited to the claim scope; unsupported regions are dropped (WLNK).
* **R (reliability)** — computed as:

```
R_eff := max(0, min_path( min_claimR(path) − Φ(CL_min(path)) ))
```

Here:

* `min_claimR(path)` is the smallest justified reliability along the path from the role to the claim in the context’s support graph.
* `CL_min(path)` is the lowest congruence level on that path.
* `Φ` is the penalty function defined by the context policy; it must be monotonic (lower CL → greater penalty).

If any element in the support chain is `postulative`, the aggregate `epistemicMode` is `postulative`.

**TA/VA/LA distinctions**:

* **TA (Typing assurance)** — primary effect is to improve `CL` on edges, reducing penalties in R computation.
* **VA (Verification assurance)** — primarily raises F and the logical component of R.
* **LA (Validation assurance)** — raises empirical R and constrains G to the validated envelope.

### A.2.4:9 - Worked examples

#### A.2.4:9.1 - Formal line — *Proof as evidence for a theorem*

**Role definition (in `GraphTheory`)**  
`AxiomaticProofRole`  
- `claimRef = Theorem-12` (“Every finite acyclic graph admits a topological ordering”),  
- `claimScope = all finite DAG`,  
- `polarity = supports` (entails),  
- `epistemicMode = formal`, `assuranceUse = VA`,  
- fenced to `TheoryVersion = 3.1` (open-ended relevance as long as that version stands).

**Role assignment(s)**  
`Lemma-12.proof#AxiomaticProofRole:GraphTheory`

**Provenance sketch**  
`verifiedBy → Carrier#Proof_p1` (machine-checked), `usedCarrier → Carrier#Def_graph`.

**Effect on assurance (informative)**  
High **F** (machine-checked proof), **G** = “finite DAG”, **R** from proof-obligation integrity; potential CL penalty if an ontology bridge is used.

##### A.2.4:9.2 - Empirical line — *Sensor calibration as evidence for an accuracy claim*

**Role definition (in `Cardio_2026`)**  
`ModelFitEvidenceRole`  
- `claimRef = “Sensor S achieves ±0.3 °C accuracy in [0,70] °C under lab conditions L”`,  
- `claimScope = temperature [0,70] °C; humidity 30–50%; environment L`,  
- `polarity = supports`,  
- `epistemicMode = postulative`, `assuranceUse = LA`,  
- `weightModelRef = KD:SupportMeasure`, `decayPolicy = annual recalibration`.

**Role assignment(s)**  
`Trial-R3.csv#ModelFitEvidenceRole:Cardio_2026`

**Provenance sketch**  
`validatedBy → Carrier#Dataset_calib_v5`, `protocolRef → MethodDescription#ThermoCalibration`, `fromWorkSet → {cal_run_0502, cal_run_0503}`.

**Effect on assurance (informative)**  
**F** from formalised procedure, **G** = measured envelope, **R** from replication and CL on unit mapping; **R** decays after the policy window unless refreshed.

### A.2.4:10 - Conformance checklist (normative)

**CC-ER-01 (Type & holder)**
`U.EvidenceRole` **MUST** be held by a `U.Episteme` via `U.RoleAssignment`. Systems, services, methods, or works **MUST NOT** hold this role.

**CC-ER-02 (Context)**
Every evidence-role assignment **MUST** name a `U.BoundedContext`. Role meanings are local and do not propagate without an explicit bridge.

**CC-ER-03 (Target claim)**
Every evidence-role assignment **MUST** reference a resolvable `claimRef@version` and declare `polarity ∈ {supports | refutes | constrains | neutral}`.

**CC-ER-04 (Claim-scope)**
Every evidence-role assignment **MUST** declare `claimScope`. For formal proofs this may be the theory’s domain; for empirical evidence it is mandatory to state population, environment, and parameter envelope.

**CC-ER-05 (Timespan)**
Every evidence-role assignment **MUST** carry a non-empty `timespan`. Formal line may have open-end **only** if fenced to a fixed theory version; empirical line must have a finite or refreshable end.

**CC-ER-06 (Provenance)**
Every evidence-role assignment **MUST** anchor into the EPV-DAG (A.10). For empirical line, `fromWorkSet` must point to external `U.Work`; self-evidence is prohibited.

**CC-ER-07 (Reproducibility)**
Empirical evidence-role assignments **MUST** state `reproducibility` ∈ {replicated-independent, replicated-internal, not-replicated, irreproducible}, with references where applicable.

**CC-ER-08 (Weight discipline)**
If `weight.score` is present, `weight.modelRef` **MUST** be named and all required inputs supplied.

**CC-ER-09 (Cross-context)**
Cross-context reuse **MUST** go via `U.Alignment` bridge; record `CL_min` on the path for assurance penalties.

**CC-ER-10 (Version fences)**
If the claim or episteme versions, create a new binding; do not mutate in place.

**CC-ER-11 (No role-of-role)**
Roles never hold roles; there is no chaining of behavioural sub-roles into non-behavioural ones.

**CC-ER-12 (Terminology)**
Use *specialisation* for role refinements; reserve *sub* for mereology of systems or artefacts only.

**CC-ER-13 (Lane declaration)**
Every binding **SHALL** declare `assuranceUse ∈ {TA | VA | LA}` and, for **empirical** (LA) bindings, expose `timespan/valid_until` and `decayPolicy` so that SCR can report lane‑separated contributions and freshness (B.3).

### A.2.4:11 - Anti-patterns and remedies

| Anti-pattern                | Symptom                                                | Remedy                                                                  |
| --------------------------- | ------------------------------------------------------ | ----------------------------------------------------------------------- |
| **Data speaks for itself**  | Binding with no `context` or `claimRef`.               | Anchor to context and explicit claim; set polarity and timespan.        |
| **Evidence = the work run** | Treating `U.Work` as the episteme.                     | Keep factual record on `U.Work`; create a report episteme to bind.      |
| **Attach to system**        | Holder is `U.System`.                                  | Holder must be an episteme; system may be `claimHost`, not role holder. |
| **Global evidence**         | Using one binding across contexts with no bridge.      | Create explicit `U.Alignment` bridge; declare loss policy.              |
| **Ad-hoc weight**           | Number assigned with no declared model.                | Use context-declared model; supply required inputs.                     |
| **Service proves itself**   | Service KPI logged as evidence.                        | KPIs come from `U.Work`; service evaluation can be bound as evidence.   |
| **Scope blur**              | Mixing design-time and run-time provenance in one EPV. | Split into separate bindings; relate via claim graph or bridge.         |


### A.2.4:12 - Operators (conceptual, tooling-agnostic)

These operators extend E.6.1 citation graph capabilities for evidence analysis inside a `U.BoundedContext`:

**12.1 Per-claim evidence**
`evidenceFor(claim, t?) → Set[EvidenceRoleAssigning]`
`counterEvidenceFor(claim, t?) → Set[EvidenceRoleAssigning]`
`weight(claim, t?, model?) → score`   # returns **ordinal** at M‑mode; **numeric** at M‑2/F‑mode.  # [M/F]

**12.2 Decay and windows**
`window(claim, [t0,t1])` — filter evidence-role assignments by `timespan`.
`decayedWeight(assignment, t)` — apply context decay policy.

**12.3 Replication and provenance**
`replicationLedger(binding) → Ledger`
`isIndependentReplication(binding) → boolean`

**12.4 Formal line hooks**
`proofChecks(binding) → {assistant, status, hash, kind∈{classical, constructive}}`  # [F‑\*]
`dependsOnAxioms(binding) → Set[AxiomId]`

**12.5 Empirical line hooks**
`fromWorkSet(binding) → Set[WorkId]`
`protocol(binding) → MethodDescriptionId`

### A.2.4:13 - Relations

**Builds on:**
A.2 `U.Role`, A.2.1 `U.RoleAssignment` (role as mask, binding as assignment), A.10 Evidence Graph Referring (EPV-DAG), B.3 Trust & Assurance Calculus.

**Coordinates with:**
A.3.2 `U.MethodDescription` (protocols, proof obligations), E.6.1 Epistemic Roles via `U.RoleAssignment` (didactic gateway).

**Informs:**
KD-CAL (knowledge dynamics, assurance cases), Norm-CAL (policy claims with evidence), planned `U.ServiceClauseEvaluation` (services judged from work and reported as epistemes with evidence bindings).


### A.2.4:14 - Migration notes (quick wins)

1. **Enumerate claims**: For each evidence collection, identify claims and create explicit bindings with polarity.
2. **Separate work from reports**: Facts stay on `U.Work`; create report epistemes to link as evidence.
3. **Name the calculus**: Replace free-form confidence with context-declared weight model and required inputs.
4. **Fence by version/time**: Bindings carry `timespan` and version fences; add decay class if applicable.
5. **Bridge explicitly**: Cross-context evidence goes through `U.Alignment`, not by fiat.

### A.2.4:15 - Didactic quick cards (engineer-manager ready)

These are short reminders for non-specialist readers to apply `U.EvidenceRole` correctly:

* **Evidence ≠ Work** — Work is *what happened*; Evidence is a *documented argument* (episteme) about a claim in a context.
* **Local, not global** — Evidence links *in a room* (context). Outside that room, you need a bridge (`U.Alignment`).
* **Two lines of trust** — Formal line: proof artefacts checked in a declared theory version. Empirical line: observations from Work under a declared method. Both are epistemes wearing `U.EvidenceRole`.
* **Services are promises; Work proves** — KPIs are measured from Work; service evaluations can be bound as evidence for policy claims.
* **Specialise, don’t stack** — Use specialisations of `U.EvidenceRole` to refine meaning; never chain behavioural roles into evidence.


### A.2.4:16 - SCR/RSCR audit stubs (assurance scaffolding)

These stubs allow concept-level validation of evidence-role assignments, without implying any specific tooling.

**SCR-A2.4-E1 (Assignment integrity)**
Assert: `holder` is `U.Episteme`; `context` present; `claimRef` resolves; `timespan` non-empty; provenance anchored to EPV.

**SCR-A2.4-E2 (Weight discipline)**
Assert: if `weight.score` present → `weight.modelRef` present and all required inputs provided; recompute to check.

**SCR-A2.4-E3 (Traceability)**
For empirical evidence-role assignments: assignment → `fromWorkSet` → each `U.Work` has performer `U.RoleAssignment` and timestamps; no missing hops.

**RSCR-A2.4-R1 (Regression on version bump)**
When `claimRef` or holder episteme versions change, ensure **new** bindings are created; no in-place mutation.

**RSCR-A2.4-R2 (Decay check)**
Bindings past `timespan.to` or with expired `decayClass` are flagged for review per context policy.


### A.2.4:17 - Minimal evidence-role assignment schema (informative)

```yaml
EvidenceRoleAssigning:
  id: ERB-…
  context: <BoundedContextId>
  holder: <EpistemeId>                # paper/proof/dataset/report
  role: <EvidenceRoleId>              # defined within the context, with normative properties
  timespan?: {from: ISO-8601, to: ISO-8601|null} # optional assignment window
  provenance:
    formal?: { theoryRef: <TheoryId>, proofArtifactRef: <CarrierId>, checkedBy?: <ProofCheckId> }
    empirical?: { protocolRef: <MethodDescriptionId>, fromWorkSet: [<WorkId>… ], dataCarrierRef?: <CarrierId> }
```

### A.2.4:18 - Memory hooks and acceptance cross-checks (informative)

**Memory hook:** *“Evidence links a **document** to a **claim** in a **Context**, for a **time**, with a **trail**.”*
(document = episteme; claim = scoped thesis; Context = bounded context; time = timespan/decay; trail = provenance)

**Acceptance cross-checks before publishing a binding:**

1. **Holder**: Is it a `U.Episteme`?
2. **Context**: Is the `U.BoundedContext` declared?
3. **Claim**: Does `claimRef` resolve? Is `polarity` set?
4. **Scope**: Is `claimScope` complete? For empirical, are population/env/parameters given?
5. **Timespan**: Is it finite or fenced (formal line)?
6. **Provenance**: Is EPV anchored? Any self-evidence?
7. **Reproducibility**: For empirical, is it declared?
8. **Weight**: If scored, is the model named and inputs complete?
9. **Cross-context**: If imported, is `U.Alignment` bridge in place with CL\_min recorded?
10. **No role-of-role**: Is this role bound directly to an episteme without chaining behavioural roles?

### A.2.4:End

## A.2.5 - U.RoleStateGraph: The Named State Space of a Role

### A.2.5:1 - Purpose & scope (why this exists)

A **role** is not only a name; it is a *trajectory of admissible states* that governs when, and under which conditions, a holder of that role may **enact** steps of a `U.MethodDescription`. FPF therefore introduces a first‑class intensional object:

> **`U.RoleStateGraph` (RSG)** — the **finite, named state space** of a **`U.Role` in a given `U.BoundedContext`**, with transitions guarded by conditions over the **Role Characterisation Space (RCS)** and contextual events.

The RSG is the **gate** between *assignment* (`U.RoleAssignment`) and *action* (`U.Work`). A step may be performed **only** when the performer’s assignment is **in an enactable RSG state** at the relevant **Window** (time slice) and this is **proven** by a contemporaneous **StateAssertion** (verdict of `U.Evaluation` against the state’s **Checklist**).


### A.2.5:2 - Problem frame (what goes wrong without an RSG)

1. **Readiness blur.** Teams conflate “has the badge” with “is fit to act now”. Without explicit states (*Ready*, *Calibrated*, *Authorized*, *Suspended*…), enactment checks dissolve into ad‑hoc judgement.
2. **Checklist drift.** Criteria for “ready/approved” live in scattered documents; there is no single conceptual anchor tying them to the role.
3. **Workflow/role confusion.** “State” of a *workflow* (according to workplan) is mistaken for the *state of a role* (eligibility to enact).
4. **Status ≠ enactment.** Epistemic/Normative roles (e.g., *NormativeStandard*, *ApprovedSpecification*) need *statuses* that are **not enactable**, yet are used to gate decisions.
5. **Cross‑context substitution by name.** Labels like *Approved* or *Ready* silently cross contexts with different criteria; the loss is hidden and unaudited.

**Consequences.** Violations of **Strict Distinction (A.7)** and **Didactic Primacy (E.12)**: ambiguous authority to act, unsafe SoD, and non‑reproducible evaluations.


### A.2.5:3 - Core idea (didactic)

Think of a **Role** as a **mask**, and the **RSG** as the **traffic lights for that mask** inside one context of meaning.

* The **nodes** are **named states** (*Ready*, *Degraded*, *Suspended*, *Approved*, *Obsolete*…).
* The **edges** are **transitions** with **guards** (checkable conditions over RCS characteristics and contextual events, e.g., *CalibrationAge ≤ 30d*; *AuthorizationSpeechAct recorded*).
* Each **state** is paired with a **Checklist** (criteria you test to issue a **StateAssertion** for a given **Window**).
* Some states are **enactable = true** (green lights); others are **not enactable** (status lights) and therefore can **gate decisions** but **cannot** directly authorize `U.Work`.

> **One sentence.** **RSG says *when a badge is green*.** The Checklist proves it, the **StateAssertion** records it, and the Method step may proceed.


### A.2.5:4 - Minimal vocabulary (this pattern only)

* **`U.RoleStateGraph` (RSG).** Intensional object *owned by* `(Role, Context)`. Finite set of named **States** and typed **Transitions** with guards.
* **RSG.State.** Intensional **named place**. Properties:

  * `enactable ∈ {true,false}` — whether being in this state authorizes enactment of steps that require this role.
  * `initial?`, `terminal?` — optional markers for lifecycle reasoning.
* **RSG.Transition.** Edge `state_i → state_j` with **Guard** (predicate over RCS characteristics and/or contextual events such as `U.SpeechAct`, `U.Observation`, `U.Evaluation` results).
* **RCS (Role Characterisation Space).** The **characteristic bundle** that characterises this role in this Context (e.g., *CalibrationAge*, *AuthorizationScope*, *FatigueIndex*, *IndependenceFlag*, *EvidenceFreshness*). *(Defined in A.2 Role Taxonomy / RoleDescription.)*
* **State Checklist (description).** A **RoleDescription** component that enumerates **criteria** to test whether a holder can legitimately be treated as **in** a given state for a **Window**. *(Description, not the state itself.)*
* **`U.Evaluation` → StateAssertion (verdict).** The **result** of applying the state’s Checklist to a **concrete holder** at a **time window**, yielding a **verdict** “IN‑STATE(S) @Window” with provenance to observations/evidence.
* **Window.** Temporal interval to which the StateAssertion applies (e.g., `[2025‑05‑01, 2025‑06‑01]`).

> **Strict distinction note.**
>
> * **RSG** and its **States** are **intensionals** (what the role *is allowed to be*).
> * **Checklists** and **StateAssertions** are **descriptions/evaluations** (how we *know* a specific holder *is* in that state now).


### A.2.5:5 - What an RSG is **not** (guardrails)

* **Not a workflow.** RSG transitions do **not** encode task order; they encode **eligibility changes** of the *role*.
* **Not a capability list.** RSG is **authorization/readiness over time**, distinct from `U.Capability` (ability).
* **Not a global status set.** RSG lives **inside one Context**; the label *Ready* in another Context is **a different state** unless bridged (F.9).
* **Not a log.** RSG is not a history. Histories are **StateAssertions** over Windows; **`U.Work`** is the record of enactments.
* **Not a document lifecycle.** Epistemic role RSGs can *look like* document lifecycles, but they remain **role‑status graphs**; the **carrier** lifecycle stays separate (A.7, `U.Carrier`).


### A.2.5:6 - Invariants (preview)

1. **Locality.** `RSG(Role, Context)` is defined **only** within that `U.BoundedContext`.
2. **Finiteness.** The **State** set is finite and named.
3. **Checklist pairing.** Every State has a **Checklist** in the Role’s **RoleDescription**; every enactable State has **at least one** observable criterion.
4. **Green‑gate discipline.** A Method step requiring `Role` may proceed **only** if a contemporaneous **StateAssertion** exists for an **enactable** State.
5. **No silent Cross‑context reuse.** Cross‑Context reuse requires a **Bridge** with CL and loss notes; local `⊥/≤/⊗` always prevail.

### A.2.5:7 - Formal structure of an RSG (intensional, context‑local)

> **Definition.** For a given **`U.Role`** in a given **`U.BoundedContext`**, its **`U.RoleStateGraph`** is the tuple
> `RSG(Role, Context) = ⟨S, S_en, T, Guard, init?⟩`, where:

* **`S`** — a **finite set of named States** (`StateName ∈ Tech register`, with a Plain label). Names are **local to `(Role, Context)`**.
* **`S_en ⊆ S`** — the subset of **enactable** states (“green lights”). States in `S \ S_en` are **status‑only** (not enactable).
* **`T ⊆ S × S`** — a set of **typed transitions** `sᵢ → sⱼ`. Transitions are optional; the RSG may be acyclic or cyclic.
* **`Guard`** — for each transition (and optionally for state maintenance), a **predicate over**:

  * the role’s **RCS snapshot** at a **Window** (values on named characteristics; see A.2.3), and
  * **Context events** (e.g., presence of a `U.SpeechAct`, freshness of `U.Observation`, validity of a prior `U.Evaluation`).
* **`init? : S → {true,false}`** — optionally marks **initial** state(s). (Useful for lifecycles; not required for gating.)

**Naming discipline (RSG‑N1…N3).**

1. **RSG‑N1 (Minimal set).** `|S| ≥ 1`. At least **one** state must exist; if **no** state is enactable, the role is **status‑only** in this Context.
2. **RSG‑N2 (Disjoint labels).** State names are **unique** within `(Role, Context)`; reusing global labels (e.g., “Ready”) across contexts is allowed **only** via Bridges (F.9).
3. **RSG‑N3 (Human scale).** For didactics, **≤ 7 states** is the default target; exceeding it requires a one‑sentence rationale (“distinct gate we will actually use”).


### A.2.5:8 - Enactability & Checklist semantics (how a state is *known*, now)

An RSG **does not** determine history; it determines **what counts as being in a state**, and which states **authorize enactment**.

#### A.2.5:8.1 - State Checklists (description, not the state)

For each `s ∈ S`, the **RoleDescription** (A.2.3) includes a **State Checklist** `Checklist(s)` — a **named set of criteria** that can be evaluated at a **Window** to test “**holder is in state `s`**”.

* **Criterion kinds (illustrative):**

  * **Threshold over RCS characteristic:** `CalibrationAge ≤ 30 days`.
  * **Presence of act:** `AuthorizationSpeechAct exists within 90 days`.
  * **Evidence freshness:** `Evidence(type=SafetyTest).age ≤ 12 months`.
  * **SoD flag:** `IndependenceFlag = true`.
  * **External status:** `StandardStatus = Approved`.

> **Strict distinction.** `Checklist(s)` is a **description**; the **state** `s` is an **intensional place** in the role’s RSG.

#### A.2.5:8.2 - From Checklist to **StateAssertion** (verdict of `U.Evaluation`)

Evaluating `Checklist(s)` at a **Window** produces an **`U.Evaluation` verdict**:

> **`StateAssertion(holder, Role, Context, s, Window)`** — “*For this Window, this holder **is** in state `s`*”, with provenance to the actual observations/evidence.

**Rules (RSG‑C1…C5).**

* **RSG‑C1 (All‑must‑hold).** A `StateAssertion` **MUST** justify that **all required criteria** in `Checklist(s)` hold at the Window.
* **RSG‑C2 (Window freshness).** Each criterion **MUST** define its freshness window; if omitted, default is **instantaneous** at the Window’s end time.
* **RSG‑C3 (No guess).** Pure opinion is disallowed; every criterion is grounded in **observable facts** (`U.Observation`, `U.Work` record, `U.SpeechAct`, or a derived `U.Evaluation`).
* **RSG‑C4 (Non‑monotonic over time).** A `StateAssertion` is **not** permanent; once the Window ends, a new evaluation is needed unless a **maintenance guard** keeps it valid (see 8.3).
* **RSG‑C5 (Uniqueness not required).** Multiple states may be asserted for the same Window if their criteria do not conflict (e.g., `Ready` and `Authorized`). **Enactability** is governed by §8.4.

#### A.2.5:8.3 - Transitions & guards (admission, maintenance, exit)

RSG transitions **express how eligibility changes** when guards fire. Guards are **predicates**; the RSG stays **notation‑neutral**.

* **Admission guard (`→ s`)** declares **conditions to enter** state `s`.
* **Maintenance guard (`s ↺`)** must hold to **remain** in `s` (e.g., *FatigueIndex < 0.8*, checked every shift).
* **Exit guard (`s →`)** declares **conditions to leave** `s` (e.g., *CalibrationAge > 30d*).

**Rules (RSG‑G1…G3).**

* **RSG‑G1 (Checklists vs guards).** Checklists decide **recognition** (“am I in `s` now?”). Guards describe **change** (“what moves me in/out of `s`?”). They may reuse the **same predicates**; their roles are distinct.
* **RSG‑G2 (No control‑flow).** Guards may refer to **events** (e.g., “Calibration completed”), but RSG is **not a task graph**; it does not prescribe task order.
* **RSG‑G3 (Observable basis).** Every guard references **observable** RCS characteristics or recorded events (no hidden timers).

#### A.2.5:8.4 - The **Green‑Gate Law** (enactment gating)

> **Law (RSG‑E1).** A `U.MethodDescription` step that **requires** role `R` **may be enacted** at Window `W` **iff** there exists a `StateAssertion(holder, R, Context, s, W)` with `s ∈ S_en`.

Corollaries:

* **RSG‑E2 (Specialization lift).** If the step requires a **general role** `R`, and the holder has a `StateAssertion` for a **specialist role** `R' ≤ R` in an **enactable** state whose **lift** (see §9.1) is enactable for `R`, the gate passes.
* **RSG‑E3 (Bundle gate).** If the step requires a **bundle** `R* = R₁ ⊗ … ⊗ Rₙ`, enactment requires **n distinct `StateAssertions`** meeting RSG‑E1 for each `Rᵢ` (unless the Context defines a **CompositeRole** with its own RSG; see §9.3).
* **RSG‑E4 (Status‑only roles).** Roles with `S_en = ∅` can **never** authorize enactment; they may **gate decisions** (e.g., *ApprovedSpecRole*) but not `U.Work`.


### A.2.5:9 - Interaction with role algebra (`≤`, `⊥`, `⊗`) and refinement

#### A.2.5:9.1 - Specialization (`≤`) — RSG refinement map

When **`R' ≤ R`** (Specialist role refines General role) **in the same Context**, their RSGs **must align** by a **refinement map**.

> **Rule (RSG‑R1 Refinement).** There exists a **surjective mapping**
> `π : S(R') → S(R)` such that:
>
> 1. **Enactability preservation:** `s' ∈ S_en(R') ⇒ π(s') ∈ S_en(R)`.
> 2. **Checklist entailment:** `Checklist_R'(s') ⇒ Checklist_R(π(s'))` (each specialist state’s criteria **imply** the general state’s criteria).
> 3. **Guard monotonicity (informal):** Transitions in `R'` **do not weaken** the general readiness implied by `R` (entering/exiting patterns respect π).

**Interpretation.** Being in `s'` for `R'` *guarantees* being in `π(s')` for `R`. Thus **StateAssertions lift** along π, enabling **RSG‑E2**.

**Design note.** RCS for `R'` may **extend** that of `R`; specialist states can be **stricter** (more criteria) but not **looser** than their general counterparts.

#### A.2.5:9.2 - Incompatibility (`⊥`) — state‑aware SoD

`R_A ⊥ R_B` (within the same Context) states that **a single holder** **must not** have **overlapping, enactable authority** for both roles.

> **Rule (RSG‑I1).** At **Window `W`**, a holder **violates** `R_A ⊥ R_B` iff there exist **StateAssertions**
> `… in s_A ∈ S_en(R_A)` **and** `… in s_B ∈ S_en(R_B)` **both valid at `W`**.

**Optional refinement (soft ⊥).** Contexts **may** tighten incompatibility by listing **state pairs** that are forbidden (e.g., `Ready_A ⊥ Authorized_B`), while allowing benign combinations (e.g., `Suspended_A` + `Ready_B`). By default, **any** enactable pair conflicts.

**Didactic payoff.** SoD is checked by **states in Windows**, not by static role labels.

#### A.2.5:9.3 - Bundles (`⊗`) — conjunction without product explosion

A **bundle role** `R* := R₁ ⊗ … ⊗ Rₙ` expresses “**must wear all these badges at once**”.

> **Rule (RSG‑B1).** If `R*` exists **only as a requirement macro**, **do not** construct a product RSG. The **gate** for a step requiring `R*` is satisfied by **n separate StateAssertions** `sᵢ ∈ S_en(Rᵢ)` at the same Window.

> **Rule (RSG‑B2 CompositeRole).** If the Context **declares `R*` as a first‑class `U.Role`**, it **MUST** also specify an `RSG(R*)` and an embedding `ιᵢ : S(R*) → S(Rᵢ)` that **preserves enactability**; being in an enactable state of `R*` **implies** being enactable in each `Rᵢ`.

**Rationale.** Avoid combinatorial blow‑up by default; allow a composite role **only** when the organization genuinely maintains its **own** readiness graph.

#### A.2.5:9.4 - Readiness monotonicity across specialization & bundles

* **RSG‑M1 (Specialist suffices).** If a step requires `R`, any `R' ≤ R` whose **lifted state** is enactable **suffices**.
* **RSG‑M2 (Bundle conjunctivity).** If a step requires `R₁ ⊗ R₂`, the performer must produce **both** gates (two StateAssertions), unless a CompositeRole with RSG exists and is used.


### A.2.5:10 - Guard design (types and discipline)

To keep RSGs **operational** but **not procedural**, guards draw on **observable** inputs only.

**Guard types (non‑exhaustive).**

1. **Threshold guards** over RCS characteristics
   `FatigueIndex < 0.8`, `CalibrationAge ≤ 30d`, `EvidenceFreshness(role=Tester) ≤ 90d`.
2. **Event guards** (occurrence since last Window)
   `exists SpeechAct(type=Authorization)`, `exists Evaluation(verdict=Pass, checklist=SafetyKit)`.
3. **Temporal guards** (time within range)
   `now ∈ AuthorizationValidityWindow`, `MaintenanceWindow not active`.
4. **Relational guards**
   `IndependenceFrom(holder=X) = true` (for SoD), `NoOpenIncident(severity≥High)`.

**Rules (RSG‑G4…G6).**

* **RSG‑G4 (Observable only).** Each guard **MUST** be checkable from **observable artefacts** (observations, work logs, speech acts, evaluations) or present RCS values.
* **RSG‑G5 (Context‑local semantics).** Guard semantics are **scoped to Context**; Cross‑context reuse requires a Bridge (§14 in Part 1/4, F.9).
* **RSG‑G6 (Didactic sparseness).** Prefer **few, stable guards** over many brittle micro‑conditions. If a guard encodes **task order**, you are drifting into workflow; refactor back to eligibility.

Allowed guard evidences include:
* Observation facts (measurements/metrics),
* Evaluation verdicts (checklist results),
* SpeechAct occurrences (communicative `U.Work`), identified by role, act kind, and window (e.g., “Approved(change=4711)”).

A SpeechAct can change the state (e.g., Prepared→Authorized) but does not by itself satisfy operational steps; it only opens their Green‑Gate.

### A.2.5:11 - Putting it together (one‑screen mental model)

At any **Window**:

1. **RoleAssignment exists** (A.2.1): `Holder#Role:Context`.
2. **StateAssertion(s) exist**: the holder is **in** one or more **states** as proven by checklists (`U.Evaluation`).
3. **Green‑Gate Law** applies: if at least one asserted state is **enactable**, role‑gated **Method steps** may be enacted; if all are **status‑only**, the role can **gate decisions** but **not** perform work.
4. **Role algebra** checks: specialization lifts readiness; bundles require **conjunction**; incompatibilities are detected when **two enactable states** coincide for the same holder at the same Window.

This yields a **clean separation**:

* **assignment** (RoleAssignment)
* **Readiness** (RSG + Checklists + StateAssertions)
* **Action** (`U.Work`, gated by RSG)

…and keeps meaning **local**, evidence **observable**, and reasoning **testable**.

### A.2.5:12 - Archetypal RoleStateGraphs (cross‑domain patterns)

Below are **didactic, reusable** RSG skeletons for the three principal **behavioural** role families and for **epistemic/status** roles. Names and criteria are **context‑local**; treat them as **templates** to specialise inside your `U.BoundedContext` (E.10.D1). For each RSG we list:

* **`S`** — candidate **States** (enactable states marked **\[E]**);
* **Checklist gist** — the **recognition** criteria (cf. §8.1);
* **Guards** — illustrative **admission/maintenance/exit** predicates (cf. §8.3).

> **Reminder.** Only **enactable** states (**`S_en`**) can open the **Green‑Gate** for `U.Work` (RSG‑E1). Status‑only states **gate decisions** but never execution.

#### A.2.5:12.1 - AgentialRole (decision‑capable actor)

**Context sketch:** `Ops_ChangeManagement_2025`.
**RCS (characteristics, examples):** *CompetenceLevel, FatigueIndex, IndependenceFlag, AuthorizationValidity, IncidentLoad, RiskClass.*

**States `S`**

* **Unprepared** — training incomplete; checklists fail.
* **Prepared** — training + competence thresholds met.
* **Authorized** — valid approval window present. **\[E]**
* **Ready** — `Prepared ∧ Authorized ∧ FatigueIndex < τ`. **\[E]**
* **Active** — contemporaneous **`U.Work`** step is underway under this role (**with a valid StateAssertion in the window**). **\[E]**
* **Suspended** — temporary block (incident/conflict).
* **Revoked** — authorization expired/withdrawn.

**Checklist gist**

* *Prepared*: certificates valid; recency of practice ≤ X; simulator score ≥ Y.
* *Authorized*: `exists SpeechAct(type=Approval, scope=Role, age≤30d)`.
* *Ready*: *Prepared ∧ Authorized ∧* independence from conflicting work; fatigue within limits.

**Guards**

* Admission `→ Prepared`: `ExamPassed ∧ SimulatorScore≥Y`.
* Admission `→ Authorized`: presence of approval speech‑act within window.
* Maintenance `Ready ↺`: `FatigueIndex<τ ∧ IncidentLoad≤k`.
* Exit `Ready → Suspended`: high‑severity incident assigned OR SoD violation detected.
* Exit `Authorized → Revoked`: window elapsed or explicit revoke speech‑act.

#### A.2.5:12.2 - TransformerRole (non‑agential executor of change)

**Context sketch:** `PlantOps_Pipeline_2025`.
**RCS:** *CalibrationAge, SafetyInterlock, SelfTestPass, EnvRangeOK, DegradationIndex.*

**States `S`**

* **Unavailable** — offline, missing prerequisites.
* **Calibrated** — calibration fresh; self‑test ok.
* **Permitted** — safety interlocks clear; clearance token valid.
* **Ready** — `Calibrated ∧ Permitted ∧ EnvRangeOK`. **\[E]**
* **Running** — executing a method step (**with contemporaneous StateAssertion**). **\[E]**
* **Degraded** — still operable under derated envelope. **\[E]** (if policy allows)
* **Quarantined** — suspected hazard; no enactment.

**Checklist gist**

* *Calibrated*: `CalibrationAge≤30d ∧ SelfTestPass=true`.
* *Permitted*: `SafetyInterlock = Clear ∧ NoOpenIncident(sev≥High)`.
* *Ready*: *Calibrated ∧ Permitted ∧* environment in spec.

**Guards**

* Admission `→ Calibrated`: calibration record timestamp ≤30d.
* Maintenance `Ready ↺`: env sensors within limits; no new hazard event.
* Exit `Ready → Quarantined`: detected leak OR hazard alarm.
* Transition `Running → Ready`: step completed ∧ cool‑down satisfied.
* Transition `Ready → Degraded`: `DegradationIndex∈[d₁,d₂]` ∧ derate policy active.

#### A.2.5:12.3 - ObserverRole (measurement actor, incl. SOSA/SSN style)

**Context sketch:** `Lab_Thermo_2025`.
**RCS:** *CalibrationAge, TraceabilityChainOK, DriftRate, SyncError, CleanlinessScore.*

**States `S`**

* **Unqualified** — no metrological chain.
* **Calibrated** — with traceability to standard.
* **Synchronized** — time/phase sync within tolerance.
* **In‑Range** — drift & environment within spec.
* **Measuring** — performing observation. **\[E]**
* **Stale** — calibration or sync expired.
* **Quarantined** — suspect bias/contamination.

**Checklist gist**

* *Calibrated*: traceability cert valid; calibration within period.
* *Synchronized*: `SyncError≤ε`.
* *In‑Range*: drift ≤ threshold; contamination tests passed.
* *Measuring*: *Calibrated ∧ Synchronized ∧ In‑Range* AND observation procedure active.

**Guards**

* Admission `→ Calibrated`: calibration event recorded < 180d.
* Exit `Calibrated → Stale`: calibration age > threshold.
* Exit `In‑Range → Quarantined`: contamination alert OR failed control sample.
* Transition `Measuring → In‑Range`: procedure complete.

> **Note.** Many ObserverRole states are **pre‑enactment** gates; only **Measuring** is enactable.


#### A.2.5:12.4 - Epistemic/status roles (no enactment)

These roles are **status‑only**; **`S_en = ∅`**. They **gate decisions** (e.g., can be cited, can constrain), but can never authorize `U.Work`.

##### A.2.5:12.4.1 - NormativeStandardRole

**States:** *Draft*, *Candidate*, *Approved*, *Superseded*, *Deprecated*.
**Checklist gist:** governance decision records; publication identifiers; supersession links.
**Guards:** *Approved → Superseded* on adoption of newer edition; *Candidate → Approved* after ratification vote.

##### A.2.5:12.4.2 - EvidenceRole

**States:** *Collected*, *Verified*, *Validated*, *Obsolete*, *Contested*.
**Checklist gist:** verification/validation `U.Evaluation` present; freshness window; reproducibility tag.
**Guards:** decay to *Obsolete* by age; transition to *Contested* upon counter‑evidence.

##### A.2.5:12.4.3 - RequirementRole

**States:** *Proposed*, *Accepted*, *Implemented*, *Verified*, *Waived*.
**Checklist gist:** acceptance decision; trace links to `U.Work`; verification report; waiver authorization.
**Guards:** *Accepted → Implemented* when linked executions close; *Implemented → Verified* on passed acceptance checklist; *Any → Waived* by authorized speech‑act.


### A.2.5:13 - One‑screen authoring templates (didactic cards)

Keep each RSG **teachable on one screen**. Use the following **notation‑neutral** templates when drafting RoleDescriptions (A.2.3).

#### A.2.5:13.1 - RSG card (per Role, per Context)

```
RSG for: <RoleName>   Context: <ContextName/Edition>
RCS characteristics (gist): <characteristic1>, <characteristic2>, … 
States (◉ = enactable):
  - [◉] <StateName> — checklist gist; typical admission/maintenance/exit
  - [  ] <StateName> — … 
  - … 
Green‑Gate: step requiring <RoleName> is enactable iff holder asserts any ◉ state at Window.
Role algebra hooks: specialization (≤ … ), incompatibility (⊥ … ), bundles (⊗ … ).
```

#### A.2.5:13.2 - State checklist snippet (per State)

```
State <StateName> (enactable? yes/no)
Checklist (all must hold at Window):
  - <Observable criterion 1>  (e.g., CalibrationAge ≤ 30d)
  - <Observable criterion 2>  (e.g., exists SpeechAct(Approval) age ≤ 30d)
Maintenance (optional): <predicate> (e.g., EnvRangeOK)
Evidence Graph Ref: <Observation/Evaluation ids>
```

#### A.2.5:13.3 - Specialization refinement map (R' ≤ R)

```
Refinement map π : S(R') → S(R)
R' state        π(state in R)   entailment note (why Checklist_R' ⇒ Checklist_R)
-----------     -------------    -----------------------------------------------
<Ready+>        Ready            adds stricter fatigue & independence thresholds
<Authorized+>   Authorized       requires same approval + extra duty segregation
… 
```

#### A.2.5:13.4 - SoD focus (⊥) — enactable pairs

```
Incompatibility ⊥ (applies when both sides enactable at same Window):
  <RoleA.StateX>  ⊥  <RoleB.StateY>
  <RoleA.(any ◉)> ⊥  <RoleB.(any ◉)>   // default if not refined
Rationale: <one‑line reason>
```

> **Didactic cue.** If your “template” spills beyond a screen, you’re drifting into **workflow**. Pull back to **eligibility** (RSG) and **recognition** (checklists).


### A.2.5:14 - Cross‑context adjustments (via Bridges, not imports)

RSGs are **context‑local**. When similar roles appear in different Contexts, relate them with an **Alignment Bridge** (F.9), never by silently importing state names.

#### A.2.5:14.1 - State name correspondence (lossy mapping)

**Bridge example:** *Observer readiness* across two contexts:

```
Bridge: Observer-RSG alignment
From: Lab_Thermo_2025.ObserverRole
To:   Metrology_Line_2025.ObserverRole
Map (with CL):
  Calibrated(Lab)     ≈  Calibrated(Metro)            CL=3 (minor criterion diffs)
  In‑Range(Lab)       ↘  Fit‑for‑Use(Metro)           CL=2 (Metro adds robustness test)
  Measuring(Lab)      ↔  Measuring(Metro)             CL=3
Notes: 'Synchronized' in Lab maps to 'Time‑Aligned' in Metro (terminology shift).
Losses: Metro’s 'Robustness' has no direct Lab counterpart (explicit loss recorded).
```

**Rule (RSG‑X1).** A Bridge **MUST** record **losses** and **extra criteria**; it **MUST NOT** assert identity without a stated `CL` (congruence level).

#### A.2.5:14.2 - Authorization vocabulary drift (deontic vs operational)

**Bridge note:** In some IT change contexts, “**Authorized**” (deontic) overlaps with “**Permitted**” (operational). A Bridge can **explain** the design choice:

* `Authorized(AgentialRole@ITIL)` ↔ `Permitted(TransformerRole@IEC)` with **CL=1** and a note: *operational interlock ≠ managerial approval; both required to lift to Ready under our policy.*

> **Payoff.** Bridges keep **local honesty** while enabling **Cross‑context reasoning** with explicit penalties (B.3).


### A.2.5:15 - Author conformance (write good RSGs)

When you define or revise an RSG, check these **concept‑level** rules. They are easy to hold in mind; no tooling implied.

**CC‑RSG‑01 (Locality).** State names and meanings are **scoped** to `(Role, Context)`. Reuse across contexts **only via a Bridge** (F.9).

**CC‑RSG‑02 (Enactability).** Mark **which** states are enactable (**S\_en**). If none are, the role is **status‑only** (valid); then it **cannot** open the Green‑Gate.

**CC‑RSG‑03 (Observable criteria).** Every checklist item must be **observable** (Observation, Work record, SpeechAct, or derived Evaluation). No opinions.

**CC‑RSG‑04 (Guard discipline).** Guards **gate change**, checklists **recognise state**. Don’t smuggle **task order** into guards; workflow lives elsewhere (A.15).

**CC‑RSG‑05 (Refinement map).** If you declare `R' ≤ R`, provide a **π‑map** and ensure **entailment** (RSG‑R1). Specialist states may be **stricter**, never **weaker**.

**CC‑RSG‑06 (SoD by state).** Define **⊥** in terms of **enactable pairs**. Avoid blanket ⊥ if finer, state‑aware rules reduce false conflicts.

**CC‑RSG‑07 (Human scale).** Default to **≤ 7 states**. If you exceed, add a one‑sentence **didactic rationale** (“distinct gate we will actually use”).

**CC‑RSG‑08 (Green‑Gate wiring).** Ensure every `MethodDescription` step that requires this Role **names** the **◉ states** it expects, or relies on the default “any ◉”.

**CC‑RSG‑09 (Window clarity).** Checklists specify **freshness windows**; state assertions are **Window‑bound** and **non‑permanent**.

**CC‑RSG‑10 (Status/behaviour split).** Epistemic/status roles: **`S_en = ∅`**. They gate **decisions**, not **Work**. Behavioural roles require `U.System` holders (A.2.1).

### A.2.5:16 - Extended grounding across four disciplines

Each vignette shows **(i)** the **Context**, **Role**, **RCS characteristics**, **States** (◉ = enactable), **Green‑Gate** condition, and **how a `U.Work` is gated** by a `U.RoleAssignment`+RSG. Names are **context‑local**.

#### A.2.5:16.1 - Clinical surgery (medicine)

**Context.** `Hospital.OR_2026`
**Role.** `SurgeonRole` (AgentialRole)
**RCS characteristics.** *CompetenceLevel, FatigueIndex, AuthorizationValidity, CaseComplexityBand, TeamSoD*.

**States.**

* **Unprepared** — training/recency incomplete.
* **Prepared** — credentials valid; recency ≤ 90 days.
* **Authorized** — procedure‑specific approval active.
* **Ready** — `Prepared ∧ Authorized ∧ FatigueIndex<τ ∧ TeamSoD_OK`. **◉**
* **Operating** — currently performing steps. **◉**
* **Suspended** — incident or conflict raised.
* **Revoked** — approval expired/withdrawn.

**Green‑Gate.** A `MethodDescription` step tagged `requires: SurgeonRole` is **enactable** iff the performer’s `RoleAssignment` asserts **Ready** at the **Window**.

**Work gating.**
`performedBy = Dr.Kim#SurgeonRole:Hospital.OR_2026` is **valid** for step *“Incision”* only when `Ready(Dr.Kim, SurgeonRole, OR_2026, W)` holds (checklist items: approval id, fatigue score, SoD against *AuditorRole*).


#### A.2.5:16.2 - Software operations (SRE)

**Context.** `SRE_Prod_Cluster_EU_2026`
**Role.** `IncidentCommanderRole` (AgentialRole)
**RCS characteristics.** *OnCallStatus, PageFreshness, AuthorityToken, CognitiveLoad, ConflictSoD*.

**States.**

* **Off‑Duty** — not on call.
* **On‑Call** — rota active; page reachable.
* **Authorized** — escalation token valid.
* **Ready** — `On‑Call ∧ Authorized ∧ CognitiveLoad≤k ∧ SoD_OK`. **◉**
* **RunningIncident** — commanding an active incident. **◉**
* **CoolingDown** — post‑incident refractory period.
* **Blocked** — conflict with *ChangeAuthorRole* detected.

**Green‑Gate.** Steps in *“Major Incident Process”* that `require: IncidentCommanderRole` open only with **Ready**.

**Work gating.**
`performedBy = Dana#IncidentCommanderRole:SRE_Prod_Cluster_EU_2026` is **invalid** for “Declare SEV‑1” if `ConflictSoD(ChangeAuthorRole)` holds or `PageFreshness>5 min`.


#### A.2.5:16.3 - Laboratory metrology

**Context.** `Metrology_Thermo_2026`
**Role.** `ThermometerObserverRole` (ObserverRole)
**RCS characteristics.** *CalibrationAge, DriftRate, TraceabilityChainOK, CleanlinessScore, SyncError*.

**States.**

* **Unqualified** — missing traceability.
* **Calibrated** — cert valid (≤ 180 d); drift within baseline.
* **Synchronized** — `SyncError≤ε`.
* **In‑Range** — contamination absent; env OK.
* **Measuring** — procedure active. **◉**
* **Stale** — calibration/sync expired.
* **Quarantined** — suspected bias.

**Green‑Gate.** `MethodDescription` step *“Record temperature”* is enactable only in state **Measuring** (which requires *Calibrated ∧ Synchronized ∧ In‑Range*).

**Work gating.**
`performedBy = SensorT‑17#ThermometerObserverRole:Metrology_Thermo_2026` is **rejected** if `CalibrationAge>180 d` or `ControlSampleBias>δ`.


#### A.2.5:16.4 - Governance / compliance

**Context.** `Finance_Audit_2026`
**Role.** `IndependentAuditorRole` (AgentialRole) and `EvidenceRole` (status‑only)
**RCS (auditor).** *CertificationLevel, IndependenceFlag, AssignmentToken, CaseLoad*.
**States (auditor).** **Ready**/**Auditing** as in §12.1; **⊥** with `DeveloperRole`.
**RCS (evidence).** *VerificationStatus, ValidationStatus, Age, ProvenanceChainOK*.
**States (evidence).** *Collected, Verified, Validated, Contested, Obsolete* (status‑only).

**Green‑Gate.** Audit step `requires: IndependentAuditorRole` — enactable only with **Ready** and **⊥ DeveloperRole** at the Window. Evidence states **gate decisions** (e.g., “accept finding”), never open Work.

**Work gating.**
`performedBy = Alice#IndependentAuditorRole:Finance_Audit_2026` **fails** if Alice holds any overlapping `DeveloperRole` binding in the same context.


### A.2.5:17 - Acceptance harness (static conformance)

Author‑facing checks; **notation‑free**, **concept‑level**. Use them when drafting or reviewing an RSG.

**SCR‑A.2.5‑S01 - Local scope.** Every state name is qualified by `(Role, Context)`. No global states.
**SCR‑A.2.5‑S02 - Enactability mark.** The set **S\_en** is explicit; each ◉ state is listed.
**SCR‑A.2.5‑S03 - Observable checklists.** Each state has a Checklist of **observable** predicates (Observation / Evaluation / SpeechAct / Work evidence).
**SCR‑A.2.5‑S04 - Green‑Gate wiring.** Every `MethodDescription` step that names the Role either (a) names its ◉ state(s) or (b) relies on the default “any ◉” policy; the RSG declares which.
**SCR‑A.2.5‑S05 - Guard discipline.** Guards only **gate transitions**; they do not encode task order.
**SCR‑A.2.5‑S06 - SoD by state.** Incompatibilities (⊥) are declared over **states** (or “any ◉”), not over bare role names.
**SCR‑A.2.5‑S07 - Specialisation entailment.** For every `R' ≤ R`, a refinement map `π: S(R')→S(R)` is provided; each mapped pair has an entailment note (why `Checklist_R' ⇒ Checklist_R`).
**SCR‑A.2.5‑S08 - Human scale.** `|S| ≤ 7` unless a one‑line didactic rationale is recorded.
**SCR‑A.2.5‑S09 - Status‑only roles.** If `S_en=∅`, the Role is explicitly tagged **status‑only**; it cannot open the Green‑Gate.
**SCR‑A.2.5‑S10 - Bridge discipline.** Any cross‑context reuse is via an Alignment Bridge (F.9) with recorded `CL` and losses; no silent imports.


### A.2.5:18 - Regression harness (evolution checks)

Use when **adding/removing states**, **changing criteria**, or **bridging** across contexts.

**RSCR‑A.2.5‑R01 - State churn impact.** For every added/removed/renamed state, list affected `MethodDescription` steps and `Work` validators; confirm the Green‑Gate policy remains decidable.
**RSCR‑A.2.5‑R02 - Entailment stability.** When `R' ≤ R` changes, update the `π` map and re‑justify entailments; fail the check if any previously valid entailment breaks.
**RSCR‑A.2.5‑R03 - SoD coverage.** After edits, recompute the set of **enactable pairs**; verify declared ⊥ still blocks all intended conflicts and no longer blocks permitted cases.
**RSCR‑A.2.5‑R04 - Evidence freshness.** If any checklist predicate uses **age/freshness**, ensure default Windows are documented and existing state assertions re‑evaluate accordingly.
**RSCR‑A.2.5‑R05 - Bridge congruence drift.** If a Bridge maps states with `CL=k`, and either side’s checklist changes, revisit the mapping; **do not** keep `CL` unchanged by default—raise or lower with a short rationale.
**RSCR‑A.2.5‑R06 - Status/behaviour split.** Verify behavioural roles still require `U.System` holders (A.2.1); status‑only roles still have `S_en=∅`.
**RSCR‑A.2.5‑R07 - One‑screen rule.** If cumulative edits push the RSG beyond one screen, split states or tighten criteria; record a one‑line teaching rationale if you must exceed.


### A.2.5:19 - Common failure modes (and quick remedies)

| Failure            | Symptom                               | Why it hurts                       | Quick remedy                                                              |
| ------------------ | ------------------------------------- | ---------------------------------- | ------------------------------------------------------------------------- |
| **Workflow creep** | Guards encode task order              | RSG becomes a hidden workflow model | Move ordering to `MethodDescription`; keep guards as **eligibility** only |
| **Vague criteria** | “experienced”, “mature” in checklists | Non‑decidable Green‑Gate           | Replace with observable proxies (hours, exam score, age thresholds)       |
| **Global states**  | “Ready” reused across contexts        | Meaning leakage                    | Qualify by `(Role, Context)`; use Bridges for Cross‑context talk             |
| **Over‑broad ⊥**   | Many false conflicts                  | Blocks delivery                    | Make ⊥ **state‑aware**; restrict to enactable pairs                       |
| **Missing π‑map**  | Specialisation with no entailment     | Unsafe substitutions               | Add `π` and entailment notes; otherwise drop `≤`                          |


### A.2.5:20 - Didactic script (90 seconds): how A.2.5 ties to A.2.1 & A.2.3

> \*“A role assignment says **who wears which mask where** (A.2.1). The **RoleStateGraph** says **when that mask is actually wearable**. Each role’s RSG is a **small named state space** with **checklists** for each state. Some states are **enactable** (◉): they open the **Green‑Gate** for `Work`. Others are **status‑only**: they gate decisions, never execution.
>
> A **RoleDescription** (A.2.3) is where you publish the role’s **RCS** (characteristics), its **RSG** (states + checklists + guards), and any **role algebra** (≤, ⊥, ⊗) specific to your context.
>
> In practice: a `MethodDescription` step lists **required roles**; at runtime, a `Work` record is valid only if its **performer** is a `RoleAssignment` whose RSG asserts an **enactable** state at the **Window**. That’s the Green‑Gate.
>
> Different Contexts may use the same role labels. We never assume global meaning; we relate Contexts with **Bridges** that map states and record losses.
>
> Keep each RSG **on one screen**, with **observable** checklists. If you’re writing task order, you’ve slipped into workflow—move it to the Method. If you’re writing opinions, convert them into **observables** or drop them. That’s the whole trick.”\*


### A.2.5:21 - Relations (quick pointers)

* **Builds on:** A.2.1 `U.RoleAssignment` (the binding that can assert states); A.2.3 `U.RoleDescription` (the carrier of RSG); E.10.D1 (Context discipline).
* **Enables.** A.15 (Role‑Method‑Work Alignment via Green‑Gate); B.3 (Trust penalties when crossing Bridges with lower `CL`).
* **Interacts with.** D‑cluster deontics (speech‑acts gate **Authorized**‑like states for agential roles); F.9 (state‑level alignment across contexts).

### A.2.5:End

## A.2.6 - Unified Scope Mechanism (USM): Context Slices & Scopes

> **One-line summary.** Introduces a single, context-local **scope mechanism** for all holons: **`U.ContextSlice`** (where we reason and measure) and a family of **set-valued scope types** (**USM scope objects, `U.Scope`**), specialized as **`U.ClaimScope`** for epistemes (**G** in **F–G–R**), **`U.WorkScope`** for system capabilities, and **`U.PublicationScope`** for publication carriers; with one algebra (∩ / SpanUnion / translate / widen / narrow / refit) and uniform Cross-context handling (Bridge + CL).

**Replaces / deprecates.**
This pattern **supersedes** the scattered use of labels *applicability*, *envelope*, *generality*, *universality* and *capability envelope* where they tried to stand in for the one scope mechanism. From now on:

* For epistemes, the only **scope type** is **`U.ClaimScope`** (nick **G** in F–G–R).
* For system capabilities, the only **scope type** is **`U.WorkScope`**.
* For publication carriers (views/cards/lanes), the only **scope type** is **`U.PublicationScope`**.
* The abstract architectural notion is **`U.Scope`** — a **set-valued USM object** over `ContextSliceSet` with its own algebra (∩ / SpanUnion / translate / widen / narrow / refit); it is **not** a `U.Characteristic` and MUST NOT appear in any `CharacteristicSpace`.

Legacy words (*applicability / envelope / generality / capability envelope*) MAY appear **only** as explanatory aliases in non‑normative notes.

**Cross‑references.**
— **C.2.3** (Unified Formality **F**) and **C.2.2** (F–G–R): this pattern **defines G** as `U.ClaimScope`.
— **A.2.2** (Capabilities): capability gating now **SHALL** use `U.WorkScope`.
— **Part B** (Bridges & CL): Cross‑context transfers **MUST** declare a Bridge with **CL**; CL affects **R**, not **F/G**.
— **Part E** (Publication discipline; e.g., **E.17 MVPK**): publication views/cards/lanes MAY declare `U.PublicationScope` to bound **where** a publication is admissible; `U.PublicationScope` MUST NOT widen the underlying `U.ClaimScope`/`U.WorkScope`. (USM supplies the scope calculus; Part E supplies publication discipline.)

### A.2.6:1 - Purpose & Audience

This pattern gives **engineering managers and assurance architects** one vocabulary, one model, and one set of operations to talk about **where** a claim holds and **under which conditions** a system can deliver a piece of **Work**. It removes the need to remember whether a document said “applicability,” a model said “envelope,” or a safety plan said “capability envelope.” **Scope is scope.** The only distinction that matters is **what carries it**:

* **Knowledge/episteme** → **Claim scope** (G).
* **System/capability** → **Work scope** (conditions under which Work at the promised measures is deliverable).

With USM, teams can:

* specify, compare, and compose scope **without translation games**;
* gate ESG and Method–Work steps with **observable, context‑local scope checks**;
* cross Contexts safely using Bridges and **explicit CL penalties** applied to **R**.

This pattern **defines** the **scope mechanism** (Context slices, set‑valued scopes, algebra, and guard usage) and the canonical **lexicon** (Claim scope (G), Work scope). It does **not** prescribe which Contexts must widen/narrow scope, nor which assurance levels are required; those are set by context‑local ESG and Method–Work policies, which SHALL reference the mechanisms defined here.

### A.2.6:2 - Context

#### A.2.6:2.1 - Cross‑disciplinary pressures

Modern projects couple **formal specs**, **data‑driven models**, **safety cases**, and **operational playbooks**. Each artifact must say **where it is valid**—yet terminology drifts:

* Standards and specs often say *applicability* or *scope*.
* Modeling communities say *envelope*.
* Safety and performance documents speak about *capability envelope*.
* Knowledge patterns have used *generality* (G) as if it were “more abstract,” when we actually need “**where the statement holds**.”

#### A.2.6:2.2 - context‑local reasoning

FPF is context‑local: decisions, checks, and state assertions are **valid inside a bounded context**. Every practical question—*Is this claim usable here? Can this capability deliver that Work now?*—must be answered **on a concrete slice of context** (terminology, versions, environmental parameters, time selector **Γ\_time**). USM provides a first‑class object for such slices and a single scope calculus atop them.

#### A.2.6:2.3 - Minimal, composable trust math

In **F–G–R**:

* **F** (formality) is “how strictly a claim is expressed” (C.2.3).
* **G** must be “**where it holds**,” not “how abstract it sounds.”
* **R** measures evidence and decays/penalties (freshness, CL).

When **G** is a **set‑valued scope**, composition becomes precise: serial dependencies **intersect** scopes; parallel, independently supported lines can publish a **SpanUnion**—but only where each line is supported.


### A.2.6:3 - Problem

1. **Synonym soup.** *Applicability, envelope, generality, capability envelope*—different labels for the **same mechanism** led to mismatches in gating, review, and reuse.
2. **Abstraction confusion.** Calling G “generality” invited teams to treat “more abstract wording” as “broader scope,” silently masking unstated assumptions.
3. **Split mechanics.** Episteme vs system text used different algebra and guard language, though **the same set operations** were meant.
4. **Cross‑context opacity.** Transfers between Contexts lacked a shared carrier and a rule for what changes (trust) vs what stays (scope).
5. **Overloaded words.** *Validity* clashed with **Validation Assurance (LA)**; *operation/operational* clashed with **Work/Run** in A.15, producing governance ambiguity.


### A.2.6:4 - Forces

| Force                                             | Tension to resolve                                                                                                                                               |
| ------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **One mechanism vs two worlds**                   | We must serve both **knowledge about the world** (claims) and **doing work in the world** (capabilities) **without** duplicating concepts.                       |
| **Locality vs interoperability**                  | Scope must be **context‑local** and precisely checkable, yet transferable across Contexts via Bridges **without redefining** the characteristic.                       |
| **Expressivity vs minimal vocabulary**            | Teams need to capture rich conditions (time windows, environment, versions) but not explode the lexicon into “envelope/applicability/…” variants.                |
| **Static content vs operational change**          | Claims may hold broadly while current operations are narrow (or vice versa). The mechanism must keep “what is true” and “what can be done” aligned yet distinct. |
| **Open‑world exploration vs closed‑world gating** | Exploration benefits from permissive drafts; **gates** require crisp, observable checks. The same scope object must support both.                                |


### A.2.6:5 - Solution — Overview (preview; full definitions in Part 2)

**USM** introduces:

* **`U.ContextSlice`** — an addressable **slice of a bounded context** (terminology, parameter ranges, versions/Standards, and a mandatory **Γ\_time** selector). All scope checks are performed **on slices**.
* **`U.Scope`** — the abstract **set‑valued scope object** over `U.ContextSlice`.
* **Specializations:**
  **`U.ClaimScope`** (nick **G**) on `U.Episteme` (“**where the claim holds**”),
  **`U.WorkScope`** on `U.Capability` (“**where the capability can deliver Work at declared measures within qualification windows**”), and
  **`U.PublicationScope`** on publication carriers (“**where the publication surface is admissible**”).
* **One algebra:** serial **intersection**, parallel **SpanUnion** (only where supported), **translate** via Bridge (CL affects **R**, not **F/G**), and **widen / narrow / refit** operations for scope evolution.

**Lexical commitments (normative):**
— In normative text and guards, use **Claim scope (G)**, **Work scope**, and **Publication scope**.  
— Do **not** name the characteristic “applicability/envelope/generality/capability envelope/**publication applicability**/validity.” Those words are permitted only as explanatory aliases in notes.

### A.2.6:6 - Normative Definitions

#### A.2.6:6.0 - USM as a `U.Mechanism.Intension` (normalization for A.6.1/A.6.5)

**Intent.** This subsection makes the **USM** definition in A.2.6 explicitly conform to the
`U.Mechanism` *intension* requirements (A.6.1) and the `…Slot` / `…Ref` lexical discipline (A.6.5),
without changing USM’s meaning.

**USM Mechanism.Intension (normative; A.6.1 decomposition).**

* **Imports (USM).** `U.ContextSlice`, `U.ContextSliceSet`, Part B **Bridge/CL** (`U.Bridge`, `U.CongruenceLevel`), and `U.GammaTimePolicy`.
* **BaseType (USM).** `U.ContextSliceSet` (set‑valued scope objects range over sets of addressable `U.ContextSlice`).
* **SliceSet (USM).** `U.ContextSliceSet` (addressable `U.ContextSlice`s; see §6.1).
* **SubjectKind (USM).** `U.Scope` with kind specialisations:  
  `U.ClaimScope ⊑ U.Scope`, `U.WorkScope ⊑ U.Scope`, `U.PublicationScope ⊑ U.Scope`.
* **ExtentRule (USM).** The quantifier domain is the set of **well‑formed scope objects** over the SliceSet: `Extension(U.Scope, slice) = { S | S ⊆ U.ContextSliceSet }`.
* **ResultKind? (USM).** `U.Scope` (for operators that return scopes, e.g., `∩`, `SpanUnion`, `translate`).

**SlotIndex (USM) for operators/guards (normative; A.6.0:4.1.1 + A.6.5).**  
These SlotKinds are stable names for signatures, substitution laws, and guard templates; they are **not** additional data slots on carriers.

| SlotKind             | ValueKind              | refMode  | Meaning |
|----------------------|------------------------|----------|---------|
| `ScopeSlot`          | `U.Scope`              | byRef    | A scope object (set of slices) owned by a carrier |
| `LeftScopeSlot`      | `U.Scope`              | byRef    | Left scope operand (binary ops/relations) |
| `RightScopeSlot`     | `U.Scope`              | byRef    | Right scope operand (binary ops/relations) |
| `ScopeFamilySlot`    | `Set[U.Scope]`          | byRef    | Finite family of scopes (for `SpanUnion`) |
| `SliceSlot`          | `U.ContextSlice`       | byValue  | A single addressable slice (membership target) |
| `SliceSetSlot`       | `U.ContextSliceSet`    | byRef    | A finite target set of slices (coverage target) |
| `BridgeRef`          | `U.Bridge`             | byRef    | Bridge used for `translate` / Cross‑context guards |
| `CLSlot`             | `U.CongruenceLevel`    | byValue  | Congruence Level bound in Cross‑context guards |
| `GammaTimeSlot`      | `U.GammaTimePolicy`    | byValue  | Explicit `Γ_time` selector/policy bound in guards |

**OperationAlgebra (USM) with SlotSpecs (normative).**

* `member(SliceSlot, ScopeSlot)` — surface form: `SliceSlot ∈ ScopeSlot`.
* `subset(LeftScopeSlot, RightScopeSlot)` — surface form: `LeftScopeSlot ⊆ RightScopeSlot`.
* `intersect(LeftScopeSlot, RightScopeSlot) → U.Scope` — surface form: `LeftScopeSlot ∩ RightScopeSlot`.
* `spanUnion(ScopeFamilySlot) → U.Scope` — surface form: `SpanUnion(ScopeFamilySlot)`.
* `translate(BridgeRef, ScopeSlot) → U.Scope` — Cross‑context mapping via Bridge.
* `widen(LeftScopeSlot, RightScopeSlot)` — Δ‑move, requires `LeftScopeSlot ⊂ RightScopeSlot`.
* `narrow(LeftScopeSlot, RightScopeSlot)` — Δ‑move, requires `RightScopeSlot ⊂ LeftScopeSlot`.
* `refit(LeftScopeSlot, RightScopeSlot)` — normalization, requires `LeftScopeSlot = RightScopeSlot`.

**Derived guard predicates (USM).**

* `coversSlice(ScopeSlot, SliceSlot) := (SliceSlot ∈ ScopeSlot)`.
* `coversSet(ScopeSlot, SliceSetSlot) := (SliceSetSlot ⊆ ScopeSlot)`.

**LawSet (USM).** Serial composition uses **intersection**; parallel publication uses **SpanUnion** only with an explicit independence justification (§7.3).

**AdmissibilityConditions (USM).** Scope coverage predicates MUST be **tri‑state** under unknowns: unknown inputs yield **unknown**, and guards MUST either (a) **abstain** (fail closed) or (b) **degrade** trust in the admitting decision via **R**; unknown MUST NOT be implicitly coerced to `false`/`0`. (See also §7.1 and §10.1.)

**Applicability (USM).** USM governs **Claim/Work/Publication** scope objects inside a `U.BoundedContext`; coverage judgments are evaluated on explicit `U.ContextSlice` tuples (§6.1) and are not comparable/scorable as CHR values.

**Audit (USM).** Record scope‑aware decisions with the `TargetSlice` tuple, guard outcomes, and any Bridge+CL used (see §14.1).

**Transport (USM).** Cross‑context usage is **Bridge‑only** with explicit **CL**; CL penalties apply to `R_eff = R · Φ(CL)` and MUST NOT rewrite **F** or **G** (§7.4/§7.5).

**Γ_timePolicy (USM).** `Γ_time` is mandatory in slices and guards (§8.2); implicit “latest” is forbidden.

**PlaneRegime (USM).** Not applicable to set‑valued scope objects (no `CL^plane` effect on scopes).

**Mechanism specialisation (USM; A.6.1:4.2.1).** A bounded context MAY publish a specialisation of USM as either a refinement `USM′ ⊑ USM` (tighten LawSet/AdmissibilityConditions) or an extension `USM ⊑⁺ USM′` (add new operators/slots). Any such specialisation SHALL (i) name its parent (`USM`), (ii) declare the morphism kind (`⊑` vs `⊑⁺`), (iii) preserve the same BaseType and SlotKinds for inherited operators (no renaming), (iv) avoid adding new mandatory inputs to inherited signatures. It MAY narrow ValueKinds/refModes monotonically and add admissibility constraints, but MUST remain substitutable for the inherited USM operators.

#### A.2.6:6.1 - `U.ContextSlice` — where scope is evaluated

**Definition.** `U.ContextSlice` is an addressable, context‑local selection of a bounded context comprising:

* **Vocabulary & roles.** The active terminology, role bindings, and local dictionaries.
* **Standards & versions.** Concrete versioned interfaces, schemas, notations, or service Standards in force.
* **Environment selectors.** Named parameters/ranges (e.g., temp, humidity, platform, jurisdiction, dataset cohort).
* **Time selector `Γ_time`.** A **mandatory** selector for the temporal frame of reference (point, window, or policy), disallowing implicit “latest”.

**Semantics.** All scope checks, guards, and compositions are evaluated **inside** an explicitly named `U.ContextSlice`. Cross‑context or cross‑slice usage MUST be mediated by a Bridge (Part B) with an explicit CL rating; see §7.4.

**Addressability.** A slice MUST be identifiable via a canonical tuple (Context, vocab‑id, Standard/version ids, env selector(s), `Γ_time`). A slice MAY be a singleton or a finite set if a guard tests multiple coherent sub‑conditions. 

**Slice key (minimal).** A `U.ContextSlice` **SHALL** be addressable by a tuple containing at least: `(Context, Standard/version ids (if any), environment selectors, Γ_time)`. Contexts MAY extend this tuple (e.g., vocab/roleset ids).

#### A.2.6:6.2 - `U.Scope` — the abstract set‑valued scope property (USM kind; **not** a CSLC measurement)

**Definition.** `U.Scope ⊆ ContextSliceSet` is a **set‑valued USM property** whose values are sets of `U.ContextSlice` where a given statement, behavior, or capability is **fit‑for‑use**. It is **not** numeric; its internal order is the subset relation `⊆`. There is no “unit”. The primitive judgement is **membership**: `slice ∈ Scope`.  

+**Guard (normative).** `U.Scope`, `U.ClaimScope (G)`, `U.WorkScope`, and `U.PublicationScope` are **not** `U.Characteristic`s in the A.17/CSLC sense; do **not** include them as slots in any `U.CharacteristicSpace`, and do **not** attach normalizations/scores to them. They are **USM scope objects**.

**Operations.** USM admits:

* **Intersection `∩`** (serial composition).
* **SpanUnion** (parallel, independently supported coverage) **only when an explicit named independence assumption is declared** (features/axes named, validity window stated, evidence class cited). See **A.6.1/USM LawSet** for the normative template.
* **Translate** (Cross‑context mapping via Bridge).
* **Widen / Narrow** (monotone changes to the set).
* **Refit** (content‑preserving re‑expression; set equality).

**Locality.** `U.Scope` values are defined and reasoned about **context‑locally**. Translation between Contexts never occurs implicitly; see §7.4.

#### A.2.6:6.3 - `U.ClaimScope` (nick **G**) — scope of a claim (episteme)

**Carrier.** `U.Episteme` (claims, specifications, theories, policies).

**Meaning.** The set of `U.ContextSlice` where the **claim holds** as stated. This is **G** in the F–G–R triple. **G is not “abstraction level”**; it is the applicability area of the claim.

**Expression.** Authors SHALL declare Claim scope as explicit predicates or condition blocks (assumptions, parameter ranges, cohorts, platform/Standard versions, `Γ_time` windows).

**Path composition (serial).** Along any essential dependency path supporting the claim, the effective scope is the **intersection** of contributors’ Claim scopes (see §7.2). Empty intersection makes the path inapplicable.

**Parallel support.** Where **independent** lines of support justify disjoint areas, the episteme MAY publish a **SpanUnion** (see §7.3) limited strictly to the covered slices.

**Δ‑moves.**

* **ΔG+ (widen).** Replace scope S with S′ such that S ⊂ S′.
* **ΔG− (narrow).** Replace scope S with S′ such that S′ ⊂ S.
* **Refit.** Replace S with S′ where S′ = S (normalization, re‑parametrization).
* **Translate.** Map S across Contexts via a declared Bridge; CL penalties apply to **R**, not to **F/G**.

**Orthogonality.** Changes in **F** (form of expression) or **D/AT** (detail/abstraction tiers) do not change **G** unless the declared area of validity changes.


#### A.2.6:6.4 - `U.WorkScope` — scope of doing Work (capability)

**Carrier.** `U.Capability` (a system’s ability to deliver specified `U.Work`).

**Meaning.** The set of `U.ContextSlice` (conditions, Standards, platforms, operating parameters, `Γ_time`) under which the capability can **deliver the intended Work** at the declared **measures**, within declared **qualification windows**.

**Expression.** Capability owners SHALL declare **`U.WorkScope`** as explicit **conditions/constraints over `U.ContextSlice` only** (environment, platforms, Standards by version, resource regimes, `Γ_time`). Quantitative deliverables and operation windows are **not** part of the scope value:  
* Declare targets as **`U.WorkMeasures`** (e.g., latency ≤ L, throughput ≥ T, tolerance ≤ ε) bound in guards (WG‑2).  
* Declare inspection/recertification policies as **`U.QualificationWindow`** bound in guards (WG‑3).  
The use‑time admission requires **all** of: `WorkScope covers JobSlice` **AND** `WorkMeasures satisfied` **AND** `QualificationWindow holds`.

**Method–Work gating.** A Work step’s guard MUST check that the target slice is **covered** by the capability’s Work scope **and** that required measures and qualification windows are satisfied.

**Composition and Δ‑moves.** Work scope uses the **same algebra** as Claim scope (∩ / SpanUnion / translate / widen / narrow / refit). Translation across Contexts follows §7.4.

**Separation from knowledge.** Work scope does **not** assert a proposition about the world; it asserts **deliverability** of Work under conditions. Evidence for deliverability feeds **R** (Reliability) via measurements and monitoring.

**Required guard facets (capabilities).**  
* **`U.WorkMeasures` (mandatory).** A set of measurable targets with units and tolerated ranges, evaluated on the JobSlice.  
* **`U.QualificationWindow` (mandatory for operational use).** A time policy (point/window/rolling) stating when the capability is considered qualified; evaluated at `Γ_time`.  
These facets are **separate** from `U.WorkScope` and live in the **R‑lane** (assurance). They MUST be referenced in Method–Work guards (see §10.3 WG‑2/WG‑3).

#### A.2.6:6.5 - `U.PublicationScope` — scope of a publication (view/surface)
**Carrier.** Publication carriers (e.g., **PublicationSurface/InteropSurface** views/cards/lanes in Part E; MVPK faces).
**Meaning.** The set of `U.ContextSlice` where a **publication** (a view/card/lane about some object or morphism) is **admissible for use** without introducing claims beyond its underlying carrier.

**Relation to other scopes (normative).**
* If the publication is **about an episteme `E`**:  
  `PublicationScope(view_E) ⊆ ClaimScope(E)`.
* If the publication is **about a capability `C`**:  
  `PublicationScope(view_C) ⊆ WorkScope(C)`.
* If the publication is **about a composition and/or crosses Contexts**:  
  `PublicationScope(view) ⊆ translate(Bridge, ⋂ scopes of contributors)`; CL penalties apply to **R** only (scope set membership is unaffected).

**Expression.** Authors SHALL declare `U.PublicationScope` as explicit predicates over `U.ContextSlice` (Context, Standard/version ids, environment selectors, `Γ_time`). It MAY be **narrower** than the underlying scope (e.g., due to pin availability, labeling, or audience constraints) but MUST NOT be wider.

**Algebra & Δ‑moves.** Inherits the USM algebra (∩ / SpanUnion / translate / widen / narrow / refit). **Widen** is permitted only when the underlying `U.ClaimScope`/`U.WorkScope` widens accordingly; otherwise the publication MAY refit or narrow.

**Orthogonality to measurement.** `U.PublicationScope` is a **USM scope object** (set‑valued), not a CHR Characteristic and MUST NOT appear as a slot in a `U.CharacteristicSpace`.

**View refinement (profiles).** When a stricter publication profile/view **refines** another (e.g., a typed card that requires additional pins), its `U.PublicationScope` **MUST NOT** be wider than that of the less formal view.

### A.2.6:7 - Scope Algebra

#### A.2.6:7.1 - Membership & Coverage

* **Membership judgement.** `slice ∈ Scope` is the primitive check.
* **Coverage guard.** A guard “Scope **covers** TargetSlice” means either:

  * **singleton:** `TargetSlice ∈ Scope`, or
  * **set:** `TargetSet ⊆ Scope`.
* **No implicit expansion.** Absent an explicit declaration, guards MUST NOT treat “close” slices as covered; widening requires a ΔG+ change.

**Tri‑state admissibility under unknowns (normative; aligns A.6.1).**

* If any required input to a membership/coverage check is **unknown** (missing slice selector, unknown Standard version, unmappable Bridge leg, unspecified `Γ_time`, etc.), the check result is **unknown**, not `false`.
* Guards MUST either **abstain** (fail closed) or explicitly route the outcome through an **R‑lane degradation** policy; unknown MUST NOT be coerced to `false/0`.

#### A.2.6:7.2 - Serial Composition (Intersection)

**Rule S‑INT (serial).** For an essential dependency chain `C1 → C2 → … → Ck` that supports a claim/capability, the effective scope along that chain is:

```
Scope_serial = ⋂_{i=1..k} Scope(Ci)
```

If `Scope_serial = ∅`, the chain is **inapplicable** and MUST NOT contribute to published scope.

**Monotonicity.** Adding a new essential dependency can only narrow (or leave unchanged) the serial scope.


#### A.2.6:7.3 - Parallel Support (SpanUnion)

**Rule P‑UNION (parallel).** If there exist **independent** support lines `L₁,…,Lₙ` for the **same** claim/capability, each with serial scope `S_i`, the publisher MAY declare:

```
Scope_published = SpanUnion({S_i})  =  ⋃_{i=1..n} S_i
```

**Constraints.**

* Independence MUST be justified (different support lines must not rely on the same weakest link).
* The union MUST NOT exceed the union of supported slices; “hopeful” areas are disallowed.
* Publishers SHOULD annotate coverage density/heterogeneity (informative) to aid R assessment, but numeric “coverage” is not part of G.
* **Independence criterion.** Support lines in a **SpanUnion** MUST be partitioned so that each line has a set of **essential components** disjoint from the others’ essential components (no shared weakest link). The partition (or a certificate thereof) SHALL be referenced in the publication.

#### A.2.6:7.4 - Why a **G-ladder/levels/scales** is not needed (and **must not** be introduced)

**1) G is not an ordinal scale; it is set-valued.**
Under **USM**, `U.ClaimScope` is a **set‑valued** **USM scope object** over `U.ContextSlice`. The only well‑typed primitives are **membership** and **set operations** (`⊆`, `∩`, `⋃`). Imposing ordinal “levels” such as **G0…Gk** violates the type discipline and produces non‑invariant behavior (the **same set** could be “rated” with different numbers under different heuristics). (See also LEX‑CHR‑STRICT.)

**2) G composes via `∩` / `SpanUnion`, not via `min` / `avg`.**
USM already fixes composition: along a **dependent path** use **intersection**; across **independent support lines** publish **SpanUnion**. None of these operations relies on (or preserves) any linear order. An ordinal “G ladder” invites people to take **minimums/averages**, which is **incorrect** for sets and breaks the established algebra.

**3) A G ladder drags in “abstraction level,” which is orthogonal.**
Early “G ladders” effectively encoded **abstraction/typing** (instances → patterns → formal classes/types → up‑to‑iso). That is valuable **didactics**, but **not applicability**. We have already separated these concerns: **abstraction** is captured, if needed, by **`U.AbstractionTier (AT)`** as an optional facet; **applicability** is **`U.ClaimScope (G)`**.

**4) A G ladder breaks locality and Bridge semantics.**
Cross‑context transfer maps a **set** `Scope` via a **Bridge** and penalizes **R** by **CL**. There is no canonical way to “translate” an **ordinal G level** between Contexts: the mapped area may be **strictly narrower** or differently factored. Level numbers would become non‑portable, causing hidden loss or inflation of trust. With USM, we **translate sets** and keep the CL penalty where it belongs—**in R**, not in G.

**5) A G ladder duplicates ESG guards without adding decision power.**
What teams often want to “compress into a G number” is actually (a) the **quality of expression** and (b) the **completeness** of the declared scope. The first is an **F threshold** (e.g., require **`U.Formality ≥ F4`** so the scope is predicate‑like and addressable); the second is handled by explicit **ESG guards**: “**Scope covers TargetSlice**,” “**`Γ_time` is specified**,” and “**freshness window holds**” (R‑lane). A ladder for G adds confusion but no additional control.

**Normative directive.**
`U.ClaimScope (G)` **SHALL** remain a **set‑valued** characteristic; **no ordinal or numeric ladder SHALL be defined** for G. Authoring and gating **SHOULD** use **F thresholds** (C.2.3) and **explicit guard predicates** (A.2.6) rather than pseudo‑levels of G.

#### A.2.6:7.5 - Translation across Contexts (Bridge & CL)

**Rule T‑BRIDGE.** To use a scope in a different bounded context (room), an explicit **Bridge** MUST be declared with:

* **Mapping.** A documented mapping from source to target `U.ContextSlice` vocabulary/characteristics.
* **Congruence Level (CL).** A rating of mapping congruence.
* **Loss notes.** Any known losses, assumptions, or non‑isomorphisms.

**Effect.** The mapped scope is `T(Scope)` in the target Context. **CL penalties apply to R** (the trust in support/evidence), **not to F or G**. If mapping is coarse, the publisher SHOULD also narrow the mapped scope to the area where losses are negligible (best practice, not a requirement).


#### A.2.6:7.6 - Δ‑Operations (Widen, Narrow, Refit)

* **ΔG+ (widen).** Monotone expansion: `S ⊂ S′`. Requires new support or stronger bridges.
* **ΔG− (narrow).** Monotone restriction: `S′ ⊂ S`. Often used to remove areas invalidated by new findings.
* **Refit.** `S′ = S` after normalization (e.g., re‑parameterization, changing units, factoring common predicates). Refit MUST NOT alter membership.

**Refit (normalization).** A refit **MUST preserve membership** exactly (S′ = S). Any change that alters boundary inclusion (due to rounding, unit conversion, discretization) is a ΔG± change, not a refit.

**Edition triggers.** Any change that alters the published set (ΔG±) is a content change and MAY trigger a new edition per Context policy (see A.2.x on editions). Refit is not a content change.

#### A.2.6:7.7 - Invariants

* **I‑LOCAL.** All scope evaluation is **context‑local**. Cross‑context usage MUST follow §7.4.
* **I‑SERIAL.** Serial scope is an **intersection**; it cannot grow by adding dependencies.
* **I‑PARALLEL.** Parallel scope MAY grow by union, but only where **independently supported**.
* **I‑WLNK.** Weakest‑link applies to **F** and **R** on dependency paths; **G** follows set rules (∩ / ⋃).
* **I‑IDS.** Idempotence: Intersecting or unioning a set with itself does not change it.
* **I‑EMPTY.** Empty scope is a first‑class value; guards MUST treat it as “not applicable”.


#### A.2.6:7.8 - Empty & Partial Scopes

* **Empty scope (`∅`).** The claim/capability is **currently not usable anywhere** in the Context; guards MUST fail.
* **Partial scope.** Publishers SHOULD avoid “global” language when actual scope is thin; instead, publish explicit slices and (informatively) coverage hints to guide R assessment.


### A.2.6:8 - Locality, Time & Version Semantics

#### A.2.6:8.1 - context‑locality

Scopes are **owned and evaluated** within a `U.BoundedContext`. State assertions (ESG/RSG) and Method–Work gates MUST NOT assume that a scope declared in another Context applies verbatim; see §7.4.

#### A.2.6:8.2 - Time selector `Γ_time`

Every scope declaration and every guard MUST specify a **`Γ_time` selector** (point, window, or policy such as “rolling 180 days”) whenever time‑dependent assumptions exist. Implicit “latest” is forbidden. When `Γ_time` differs between contributors, serial intersection resolves the overlap.

#### A.2.6:8.3 - Standards, versions & notations

Scope predicates SHALL name Standards/interfaces/schemas **by version**. Changing symbols/notations with a faithful mapping does not change **G** (it may change **CL** for the mapping and thus affect **R**).

#### A.2.6:8.4 - Determinism of evaluation

Given fixed inputs (slice tuple, declared scope), the membership judgement MUST be deterministic. Guards SHALL fail closed (no membership ⇒ no use).

#### A.2.6:8.5 - Interaction with R (freshness & decay)

For empirical claims and operational capabilities, **R** typically binds evidence freshness windows. Scope does not decay with time; **trust in the support** does. Guards MAY combine “Scope covers” with “Evidence freshness holds” as separate predicates.


### A.2.6:9 - Lexical Discipline (Part E compliance)

**L‑USM‑1 (names).** Use **Claim scope (G)** for epistemes, **Work scope** for capabilities, and **Publication scope** for publication carriers. Use **Scope** only when discussing the abstract mechanism. Avoid naming any **characteristic** as “applicability,” “envelope,” “generality,” “capability envelope,” or “validity”.

**L‑USM‑2 (Work/Run).** Prefer **Work/Run** vocabulary from A.15 for system execution contexts. Do not introduce “operation/operating” as characteristic names; use **Work scope**.

**L‑USM‑3 (Validation).** “Validation/Validate” remain reserved for **LA** in assurance lanes (Part B). Do not name the scope characteristic “validity”.

**L‑USM‑4 (Domain).** “Domain” is a descriptive convenience. Scopes are evaluated on **Context slices**; guards SHALL reference slices, not generic “domains”.

**L‑USM‑5 (First mention).** On first use in a Context, include the parenthetical nick: *“Claim scope (**G**)”* to preserve the F–G–R mapping.

### A.2.6:10 - Guard Patterns (ESG & Method–Work)

#### A.2.6:10.1 - Common guard shape

A scope‑aware guard has the form:

```
Guard := ScopeCoverage AND TimePolicy AND (EvidenceFreshness?) AND (BridgePolicy?)
```

**Admissibility note (normative; A.6.1 alignment).** If `ScopeCoverage` is **unknown** (due to unknown slice keys, unmappable translation, missing `Γ_time`, etc.), the guard MUST NOT silently treat this as `false`. It MUST either abstain (fail closed) or apply an explicit R‑lane degradation policy.

Where:

* **ScopeCoverage**: `Scope covers TargetSlice` (singleton or finite set), see §7.1.
* **TimePolicy**: explicit `Γ_time` selector(s); implicit “latest” is forbidden (§8.2).
* **EvidenceFreshness**: optional R‑lane freshness/decay predicates; **separate** from ScopeCoverage (§8.5).
* **BridgePolicy**: required if the Scope and TargetSlice are in **different Contexts**; declares Bridge, CL, loss notes (§7.4).

The guard **fails closed** (no membership ⇒ denial), and evaluation is **deterministic** given the slice tuple (§8.4).


#### A.2.6:10.2 - ESG guard families (epistemes)

**EG‑1 - ClaimScopeCoverage (mandatory).**
The state transition MUST include a predicate:

```
U.ClaimScope(episteme) covers TargetSlice
```

* **Singleton**: `TargetSlice ∈ ClaimScope`.
* **Finite set**: `TargetSet ⊆ ClaimScope`.

**EG‑2 - Formality threshold (if required by ESG).**
When rigor is gated, the guard MUST reference C.2.3:

```
U.Formality(episteme) ≥ F_k
```

**EG‑3 - Evidence freshness (R‑lane).**
If the state implies trust, a separate predicate MUST assert freshness windows for bound evidence:

```
Fresh(evidence, window)  AND  (NoExpiredBindings)
```

**EG‑4 - Cross‑context usage.**
If `TargetSlice.Context ≠ episteme.Context`, the guard MUST require a declared Bridge and CL:

```
Bridge(source=episteme.Context, target=TargetSlice.Context)  AND  CL ≥ c
```

> **Effect:** CL penalties apply to **R**, not to **F/G** (§7.4). The ESG guard MAY also **narrow** the mapped Claim scope when mapping losses are known.

**EG‑5 - ΔG triggers.**
If the transition publishes a **wider** Claim scope (ΔG+), the guard MUST capture the new support or the new Bridge and, if Context policy so dictates, mint a new edition (PhaseOf).

**EG‑6 - Independence for SpanUnion (when claiming parallel scope).**
When the episteme declares a **SpanUnion** across independent lines, the guard MUST include an **independence justification** (pointer to the support partition). No independence ⇒ no union.

*(Informative note.)* Managers often combine EG‑1 (coverage) + EG‑2 (F threshold) + EG‑3 (freshness) for “Effective” or “Approved” states, and EG‑4 when adopting claims across Contexts.


#### A.2.6:10.3 - Method–Work guard families (capabilities)

**WG‑1 - WorkScopeCoverage (mandatory).**
A capability can be used to deliver a Work step only if:

```
U.WorkScope(capability) covers JobSlice
```

**WG‑2 - `U.WorkMeasures` satisfied** (mandatory for deliverables).
Guards MUST bind quantitative measures that the capability promises in the JobSlice:

```
SLO/target measures satisfied (latency ≤ L, throughput ≥ T, tolerance ≤ ε, … )
```

**WG‑3 - `U.QualificationWindow` holds** (mandatory for operational use).
Operational guards MUST assert that qualification windows (qualification/inspection/recert intervals) hold **at `Γ_time`**:

```
ValidityWindow(capability) holds at Γ_time
```

**WG‑4 - Cross‑context use of capability.**
If the JobSlice is in another Context:

```
Bridge(source=capability.Context, target=JobSlice.Context)  AND  CL ≥ c
```

CL penalties affect **R** (confidence in deliverability), **not** Work scope; however, the guard SHOULD narrow the mapped Work scope to account for known mapping losses.

**WG‑5 - Δ(WorkScope).**
When widening Work scope (new operating ranges/platforms), the guard MUST require evidence at the new slices (measures + qualification windows). Refit (e.g., new units/parametrization) requires no new evidence.


#### A.2.6:10.4 - Bridge‑aware guard macro (reusable)

A reusable macro for Cross‑context guards:

```
Guard_XContext(Scope, TargetSlice) :=
    exists Bridge b: (b.source = owner(Scope).Context AND b.target = TargetSlice.Context)
AND CL(b) ≥ c
AND Scope’ = translate(b, Scope)
AND Scope’ covers TargetSlice
AND (Apply CL penalty to R)
```

+* **Owner(Scope).** The carrier that declares the scope: an **Episteme** (for `U.ClaimScope`), a **Capability** (for `U.WorkScope`), or a **Publication carrier** (for `U.PublicationScope`).  
* **Translate(b, Scope).** The partial mapping of a set of source slices to target slices induced by Bridge **b**. If a source slice is unmappable, it is dropped. The result is a set of target slices; **CL penalties apply to R only**.
* **Penalty to R**: applied per trust calculus; F and G remain as declared.

#### A.2.6:10.5 - Selector policy (Γ\_time)

All ESG and Method–Work guards MUST spell out **`Γ_time`**:

* **Point** (“as of 2026‑03‑31T00:00Z”).
* **Window** (“rolling 180 days”).
* **Policy** (“last lab calibration within 90 days”).

Implicit “latest” is not allowed. If multiple contributors declare different policies, **serial intersection** computes the overlap (§8.2).

### A.2.6:12 - Worked Examples

> Each example declares the Context, the scope, the target slice, and shows the guard outcome. Where relevant, serial intersection, SpanUnion, and Bridge & CL are illustrated.

#### A.2.6:12.1 - Research claim (controlled narrative → predicate)

* **Context:** `MaterialsLab@2026`.
* **Episteme:** claim “Adhesive X retains ≥85 % tensile strength on Al6061 for 2 h at 120–150 °C.”
* **Claim scope (G):** `{substrate=Al6061, temp∈[120,150]°C, dwell≤2h, Γ_time = window(1y), rig=Calib‑v3}`.
* **Target slice:** `{substrate=Al6061, temp=140 °C, dwell=90 min, Γ_time=2026‑04‑02, rig=Calib‑v3}`.
* **Guard (EG‑1, EG‑2):** `covers(TargetSlice)` **true**; `U.Formality ≥ F4` **true** (predicates in spec).
* **Outcome:** state transition allowed (freshness checked separately under R).

#### A.2.6:12.2 - Cross‑context use of the research claim

* **target Context:** `AssemblyFloor@EU‑PLANT‑B`.
* **Bridge:** declared mapping of rigs and temp measurement correction; **CL=2** (loss: ±2 °C bias).
* **Mapped Claim scope:** `translate(Bridge, G)` narrows temp to `[122,148]°C`.
* **Guard (EG‑4):** Bridge present, `CL≥2` **true**; **R** is penalized per Φ(CL).
* **Outcome:** allowed; **G** remains the mapped set; **R** lowered.

#### A.2.6:12.3 - Capability: robotic weld Work scope

* **Context:** `RobotCell‑Weld@2026`.
* **Capability:** “Weld seam W at bead width 2.5 ± 0.3 mm, cycle ≤ 12 s.”
* **Work scope:** `{humidity<60 %, current∈[35,45]A, wire=ER70S‑6, Γ_time=rolling(90d), controller=FW‑2.1}`.
* **Job slice:** `{humidity=55 %, current=40A, wire=ER70S‑6, Γ_time=now, controller=FW‑2.1}`.
* **Guards (WG‑1..3):** coverage **true**; measures satisfied; qualification window **true** (controller certified 60 d ago).
* **Outcome:** capability admitted for this Work.

#### A.2.6:12.4 - Serial intersection (API + dataset compatibility)

* **Claim A (API Standard):** `v2.3` request schema with constraint “idempotent under retry”.
* **Claim B (Dataset cohort):** “metrics valid for cohort K with schema `ds‑14`”.
* **Composition:** service S depends on both A and B → **serial intersection** of Claim scopes: `{api=v2.3} ∩ {cohort=K, schema=ds‑14}`.
* **Target slice:** `{api=v2.3, cohort=K, schema=ds‑14}` → membership **true**.
* **Any drift (e.g., `ds‑15`)** empties the intersection ⇒ path inapplicable.

#### A.2.6:12.5 - Parallel support (SpanUnion) in a safety case

* **Line L1:** tests on **dry asphalt** support braking property; scope `S1={surface=dry, speed≤50 km/h}`.
* **Line L2:** simulations for **wet asphalt**; scope `S2={surface=wet, speed≤40 km/h}`.
* **Published scope:** `SpanUnion({S1,S2})` = `{(dry, ≤50), (wet, ≤40)}` with independence note (L1 empirical, L2 model‑validated).
* **Guard:** allowed; union does **not** include `(wet, 45)` because not supported.

#### A.2.6:12.6 - ML model deployment across Contexts

* **Model claim:** “AUC ≥ 0.92 on cohort K, pipeline P, features F, `Γ_time=rolling(180d)`.”
* **Claim scope:** `{cohort=K, pipeline=P, features=F, Γ_time=rolling(180d)}`.
* **target Context:** product `On‑Device@v7`, features `F’` (subset), pipeline `P’`.
* **Bridge:** declared mapping `F→F’`, `P→P’`, **CL=1** (notably lossy).
* **Guard:** Bridge present; `translate(G)` covers a **strict subset**; CL=1 penalizes **R** strongly; ESG requires **F≥F5** (executable semantics) and **freshness < 90 d**.
* **Outcome:** allowed only for the covered subset; adoption flagged with reduced **R**.


### A.2.6:13 - Playbooks (Informative)

#### A.2.6:13.1 - Manager’s 6‑step adoption checklist

1. **Name the TargetSlice.** Write the tuple (Context, versions, environment params, `Γ_time`).
2. **Check scope coverage.** “Claim/Work scope covers TargetSlice?” If **no**, either **ΔG+** (publish wider scope with support) or **decline**.
3. **Check rigor if gated.** If ESG requires it, ensure `U.Formality ≥ F_k`.
4. **Check evidence freshness (R).** Validate windows/decay policies; do not conflate with coverage.
5. **Bridge if Cross‑context.** Require declared Bridge, CL, and loss notes; accept **R** penalties.
6. **Record the decision.** Keep the slice and guard outcomes with the StateAssertion (auditability).

#### A.2.6:13.2 - Architect’s design rubric for scopes

* **Prefer predicates over prose.** Name parameters, ranges, Standards by **version**, and `Γ_time`.
* **Factor common conditions.** Use Refit to normalize units and factor shared predicates; do not widen by stealth.
* **Partition support lines.** If you plan a **SpanUnion**, document independence up front.
* **Keep scope thin & honest.** Publish what you can support; add slices as support appears (ΔG+).
* **Design Bridges early.** When interop is planned, sketch mapping characteristics and **expected CL**; plan **R** penalties.

#### A.2.6:13.3 - Review anti‑patterns & fixes

| Anti‑pattern                                    | Why it’s wrong                   | Fix                                                        |
| ----------------------------------------------- | -------------------------------- | ---------------------------------------------------------- |
| “Latest” time by default                        | Non‑deterministic; violates §8.2 | Declare `Γ_time` explicitly (point/window/policy)          |
| Using “domain” in guards                        | Not addressable; hides slices    | Replace with concrete `U.ContextSlice` tuples              |
| Treating “more abstract wording” as wider scope | Abstraction ≠ applicability      | Keep **AT/D** separate; widen **G** only with explicit ΔG+ |
| Publishing union without independence           | Overstates coverage              | Justify independence or publish serial intersection only   |
| Cross‑context use without Bridge                   | Silent semantic drift            | Require Bridge + CL; apply **R** penalties                 |

#### A.2.6:13.4 - Minimal DSL snippet for scope blocks (illustrative)

```
claimScope:
  Context: MaterialsLab@2026
  Standards:
    - rig: Calib-v3
    - api: v2.3
  env:
    substrate: Al6061
    temp: [120, 150] # °C
    dwell: { max: "2h" }
  gamma_time: { window_days: 365 }
```

*(Illustrative only; the specification does not mandate a particular syntax.)*

#### A.2.6:13.5 - Profiles as Scope configurations (informative)
**Idea.** A **Scope profile** is a **named, editioned configuration** that expands to a concrete `U.Scope` predicate block (over `U.ContextSlice`), used to avoid repetition and to keep declarations consistent across carriers.

**Rules.**
* **P1 (Expansion).** Profiles are macros: guards **MUST** expand them to explicit predicates before evaluating `Scope covers TargetSlice`.
* **P2 (Edition).** Profiles are editioned; changing a profile’s predicates is a content change for any carrier that references it.
* **P3 (No stealth widen).** A profile update MUST NOT implicitly widen a carrier’s published scope; ΔG+ must be explicit in that carrier.
* **P4 (Bridge awareness).** If a profile implies Cross‑context use, it MUST name the Bridge and CL policy; CL penalties apply to **R** only.
* **P5 (Locality).** Profiles are context‑local conveniences; they do not introduce new scope types.

**Examples (illustrative).**  
— An engineering context defines `Ops‑Lab‑v3` as a profile pinning Standards, environment selectors, and a rolling `Γ_time` policy; claims, capabilities, and publications may reference it as a shorthand.  
— A publication stack defines `TechCard‑Lite@Σ` as a profile that **narrows** `U.PublicationScope` to slices where required pins are available.

### A.2.6:14 - Governance Hooks & Audits

#### A.2.6:14.1 - Governance metadata (normative)

Contexts that adopt USM SHALL record, per scope‑aware decision:

* **Owner.** Episteme (for Claim scope) or Capability (for Work scope).
* **TargetSlice tuple.** Context, vocab/roles, versioned Standards, environment selectors, **`Γ_time`**.
* **Guard outcomes.** Membership result, Bound measures (for Work scope), Freshness predicates (R).
* **Bridge info (if any).** Mapping summary, **CL**, loss notes, applied R penalty.
* **ΔG log.** Widen/narrow/refit; edition policy outcome.

#### A.2.6:14.2 - USM compliance levels (informative)

* **USM‑Ready.** Context declares adoption; editors trained; lexicon updated.
* **USM‑Guarded.** All ESG/Method–Work guards use Claim/Work scope and `Γ_time`.
* **USM‑Auditable.** Decision records include TargetSlice tuples and Bridge/CL details.
* **USM‑Composed.** Serial intersection and SpanUnion are implemented in composition tooling.

#### A.2.6:14.3 - Audit checklist (informative)

* Does each guard **name** a concrete **TargetSlice**?
* Is **membership** deterministically recomputable from published predicates?
* Are **freshness** and **coverage** separate predicates?
* For Cross‑context use: is there a **Bridge** with **CL** and loss notes?
* For parallel support: is **independence** justified?

#### A.2.6:14.4 - Risk controls (informative)

* **Silent widening.** Require ΔG+ review; flag any scope increase without new support/Bridge.
* **Opaque slices.** Disallow “domain” placeholders; enforce addressable selectors.
* **Time drift.** Require `Γ_time` policies (rolling windows) for time‑sensitive scopes.


### A.2.6:15 - Cross‑Pattern Coordination

#### A.2.6:15.1 - With F–G–R (C.2.2)

* **G is Claim scope.** Use set algebra (∩ / SpanUnion).
* **F** remains the expression rigor (C.2.3); **R** captures evidence freshness and CL penalties.
* **Weakest‑link.** On dependency paths: **F\_composite = min(F)**, **R\_composite = min(R)**; **G** follows §7.2–§7.3 (set rules).

#### A.2.6:15.2 - With Formality (C.2.3)

* **No conflation.** Raising **F** does not change **G** unless scope predicates change.
* **Guarding rigor.** ESG may use `U.Formality ≥ F_k` alongside scope coverage.

#### A.2.6:15.3 - With Work & Run (A.15)

* **Work scope** aligns with the **execution context** of `U.Work`.
* Method–Work gates use **Work scope coverage** plus **measures** and **qualification windows**.

#### A.2.6:15.4 - With Bridges & CL (Part B)

* **CL only impacts R.** CL penalties reduce trust; they never rewrite **F** or **G**.
* **Best practice.** Narrow mapped scopes where mapping losses are material.

#### A.2.6:15.5 - With Capability governance (A.2.2)

* Capabilities MUST declare **Work scope**, **measures**, **qualification windows**; gates MUST verify all three.
* Capability refits that preserve the set (unit changes) are **Refit**, not Δ(WorkScope).


### A.2.6:16 - Extended FAQ (informative)

**Q1. Is “Claim scope” the same as “domain”?**
**No.** “Domain” is descriptive and often fuzzy. **Claim scope** is **addressable**: it names concrete `U.ContextSlice` conditions and a **`Γ_time`** policy. Guards MUST reference slices, not generic “domains”.

**Q2. How do we express partial coverage across different cohorts or platforms?**
Declare each supported serial scope (`S₁, S₂, …`) and publish **SpanUnion({Sᵢ})** with independence justification. Do **not** include unsupported slices.

**Q3. Can raising F (formalizing) widen G?**
Only if the formalization **explicitly changes** the scope predicates (ΔG+). Formalization alone does not widen scope.

**Q4. What is the difference between Work scope and SLOs?**
**Work scope** is **where** the capability can deliver; **measures** within the guard are **what** it promises there (SLO targets). Both are required at use time (WG‑1..3).

**Q5. Can we assign numeric coverage to G?**
Not normatively. G is set‑valued. You MAY attach **informative** coverage metrics (e.g., proportions) to aid **R** assessment, but guards use set membership.

**Q6. How do we handle “latest data” scopes?**
You don’t. Declare a **`Γ_time`** policy (e.g., rolling 90 days). “Latest” is forbidden to ensure reproducible evaluation.

**Q7. How do we move a scope to another Context?**
Declare a **Bridge** with **CL** and loss notes; compute `translate(Bridge, Scope)`; apply CL penalty to **R**; consider narrowing the mapped set.

**Q8. What about abstraction level or detail?**
Keep **AT (AbstractionTier)** and **D (Detail/Resolution)** as orthogonal, optional annotations. They never substitute for **Claim/Work scope**.

**Q9. Can a capability’s Work scope be broader than a predecessor claim’s Claim scope on a dependency path?**
They are on different carriers. In a serial dependency, the **effective** scope is the **intersection**; the broader one does not dominate.

**Q10. When does an empty scope make sense?**
It indicates “not usable anywhere (here, now)”. Guards MUST fail. This is common during early drafting or after a refutation.

**Summary.** Across all Contexts, two stable notions recur: (1) **evaluate in a concrete context** (→ `U.ContextSlice`), and (2) **declare where something holds/is deliverable** (→ set‑valued **Scope**). “Context of use,” “operating modes,” “targets,” “class extension,” and “OSED” are all Context‑flavored presentations of **Claim scope** or **Work scope**. Terms like *validity* and *operation* are semantically close but collide with **LA** and FPF’s **Work/Run** lexicon; we therefore **do not** adopt them as characteristic names.

**Why these names (decision grounds):**

* **“Scope” wins over “envelope/applicability/validity”.** It is short, **self‑documenting**, and already idiomatic in SRE/SW, while “validity” clashes with **Validation Assurance (LA)** and “envelope” suggests geometry, not **membership**.
* **“Claim scope” vs “Work scope”.** Two‑word compounds meet the FPF clarity rule: the first token reveals the **carrier** (Claim vs Work/Capability), the second the **mechanism** (scope).
* **Keep **G**.** The F–G–R triple is canonical; we retain **G** as nickname for **Claim scope**.
* **“Context slice”** is the only term that makes the evaluation target **addressable** (Context, versions, params, **Γ\_time**).
* **“Operation/operating/validity” avoided.** They are **overloaded** in existing FPF lanes (Work/Run, LA) and create policy ambiguities in guards.

##### A.2.6:17.4.3.2 - Phrasebook (for editors, normative)

* Use **“Claim scope (G) covers TargetSlice”** and **“Work scope covers JobSlice”** in guards.
* Always spell **`Γ_time`**; never say “latest”.
* To compose, say: **“intersection along dependency paths; SpanUnion across independent support lines.”**
* For Cross‑context use, say: **“via Bridge; CL penalties apply to R (trust), not to F/G (content/scope).”**
* When widening/narrowing, write **“ΔG+ / ΔG−”** and log the support change; use **“Refit”** for unit/param normalization.

##### A.2.6:17.4.3.3 - Rosetta summary (informative, for rationale box)

| local context phrase                          | Use in USM wording                                          |
| ------------------------------------------ | ----------------------------------------------------------- |
| “Context of use” (NIST, ASME/FDA)          | **Claim scope (G)** on explicit **Context slice**           |

**Outcome.** The UTS shows strong convergence across SoTA Contexts on **addressable context** and **set‑valued applicability**. F.18 therefore fixes: **Context slice**, **Scope**, **Claim scope (G)**, **Work scope**, **Publication scope** with the algebra and guard clauses mandated in A.2.6. This closes synonym drift while remaining readable for engineering managers and precise for assurance tooling.

### A.2.6:End

## A.2.7 - U.RoleAlgebra: In‑Context Role Relations

> **Type:** Definitional (D)
> **Status:** Stable
> **Normativity:** Normative

*with `requiredRoles` substitution, SoD (`⊥`), and bundle (`⊗`) hooks*

**Builds on:** A.1.1 **`U.BoundedContext`**, A.2 **Role Taxonomy**.  
**Coordinates with:** A.2.1 **`U.RoleAssignment`**, A.15 **Role–Method–Work Alignment**.

### A.2.7:1 - Problem frame

**Intent.** Provide a tiny, explicit algebra over **role types** inside one Context so engines can (a) substitute specialisations, (b) enforce separation of duties, and (c) treat frequent conjunctions as named bundles—without encoding taxonomy in RoleAssignments.

**Scope.**

* Defines three in‑Context relations/operators: specialization `≤`, incompatibility `⊥`, and bundle `⊗`.
* States substitution semantics used when checking `MethodStep.requiredRoles`.
* States overlap‑prohibition semantics used to validate RoleAssignments.

**Non‑goals.**

* No cross‑Context equivalence by label; cross‑Context reuse is **Bridge‑only** (F.9).
* No mereology; role algebra does not describe part‑of or structure membership.
* No capability model; intrinsic ability evidence lives in `U.Capability` and related patterns.

**Disambiguation.** Do not confuse role specialization `≤` with kind subsumption `⊑` (Kind‑CAL).  
`≤` is **requirement substitution** between role *types* in one Context; `⊑` is **typing** between kinds.

### A.2.7:2 - Solution (the three operators)

Role algebra relates **role types** inside **one** `U.BoundedContext`. It is **not** mereology.

#### A.2.7:2.1 - Specialization (narrower assignment)

* **Notation:** `RoleS ≤ RoleG`
* **Semantics (normative):** For any `U.RoleAssignment` with `role = RoleS` in this Context, the holder **also satisfies** requirements for `RoleG` in this Context.
* **Use:** Stable expertise ladders; privilege inheritance; “junior→senior” substitution.
* **CC‑ALG‑1.** Engines that check `requiredRoles` **MUST** treat `≤` as admissible substitution.

#### A.2.7:2.2 - Incompatibility (conceptual role incompatibility)

* **Notation:** `RoleA ⊥ RoleB`
* **Semantics (normative):** Overlapping `window`s on the same holder for assignments to both roles in this Context are **ill‑formed**.
* **Use:** Separation‑of‑duties (SoD); independence constraints (e.g., performer vs reviewer).
* **CC‑ALG‑2.** Validation **MUST** reject overlapping assignments that violate `⊥`.

#### A.2.7:2.3 - Bundles (conjunctive requirement)

* **Notation:** `RoleC := Role1 ⊗ Role2 ⊗ …`
* **Semantics:** `RoleC` is **satisfied iff** the holder has **simultaneous** valid assignments for each conjunct role (in this Context).
* **Use:** Frequent conjunctions (e.g., “On‑call Incident Commander” = *Engineer ⊗ Communicator ⊗ Decision‑Maker*).
* **CC‑ALG‑3.** Engines that check `requires: [RoleC]` **MUST** expand to conjunctive checks.

+> **Didactic guardrails.**
+> Use `≤` for lasting ladders, `⊥` for critical safety/governance, `⊗` for frequent conjunctions. Prefer listing multiple `requiredRoles` on Method steps to avoid ornate lattices.

+### A.2.7:3 - Relations

**Builds on / depends on**

* **A.1.1 `U.BoundedContext`** — the locality boundary within which the algebra holds.
* **A.2 Role Taxonomy** — role families and context‑local naming.

**Used by**

* **A.2.1 `U.RoleAssignment`** — avoids chained assignments; uses `≤/⊥/⊗` for checking and validation.
* **A.15 Role–Method–Work Alignment** — expands `requiredRoles` and enforces SoD requirements.
* **D.2** ethics/governance patterns — encode SoD and independence via `⊥`.

## A.2.8 - `U.Commitment` (Deontic Commitment Object)

> **Type:** Definitional (D)
> **Status:** Stable
> **Normativity:** Normative (unless explicitly marked informative)
> **Placement:** Part A → **A.2 Roles & Agency Kernel**
> **Refines:** A.2 (Role Taxonomy)
> **Builds on:** E.8 (authoring template), A.2.1 (RoleAssignment), A.2.6 (Scope & `Γ_time`), A.7 (Object≠Description≠Carrier), A.2.3 (`U.ServiceClause` as promise), A.15.1 (`U.Work`)
> **Purpose (one line):** Provide a minimal, reusable kernel object for deontic commitments (who is accountable, under what modality, in what scope/window, with respect to which referents, with which adjudication hooks), **explicitly separating the commitment object from its utterance descriptions** (A.7), so deontics stop “living” in naming patterns and become stable across A.6 and later governance patterns.

### A.2.8:0 - Terminology: “binding” is overloaded (normative)

The word family “bind/binding” is used throughout FPF for **technical binding** (name/slot binding, parameter binding, etc.). This pattern introduces a narrower lexical constraint: **do not use “binding” as the Tech-level term for deontic governance relations.** Use **commitment** and model it as `U.Commitment`. If source material uses “binding contract/promise” rhetoric, rewrite it into explicit `U.Commitment` fields (`subject`, `modality`, `scope/window`, `referents`, and—when auditable—`adjudication`).

This pattern therefore treats **commitment** as the canonical Tech-level term and uses `U.Commitment` as the kernel object.

If your source material uses “binding” rhetoric (e.g., “binding contract”, “legally binding promise”), treat it as Plain-level phrasing that **MUST** be rewritten into explicit `U.Commitment` fields (`subject`, `modality`, `scope/window`, `referents`, and—when auditable—`adjudication`).

### A.2.8:1 - Problem frame

FPF needs to express boundary governance and socio-technical obligations in a way that is:

* **role/agent-grounded** (someone is accountable),
* **scope-and-window explicit** (where/when the commitment holds),
* **reference-based** (no paraphrase drift; refer to claim IDs),
* **adjudicable** (if intended to be checkable, it has an evidence story).

In practice, texts use “MUST/SHALL/should”, “commits to”, “guarantees”, “SLA”, “contract”, etc. Without a stable kernel object for “the deontic binding”, authors either:

* assign agency to descriptions (“the API guarantees…”),
* smuggle admissibility gates into deontics (or vice versa),
* treat evidence as semantic truth,
* or create multiple inconsistent “contracts” across faces.

A.6.B provides routing discipline (L/A/D/E), and A.6.C provides contract-language unpacking, but both benefit from a **kernel-level** object that pins down what a `U.Commitment` is structurally (so “contract/binding” rhetoric does not leak back in as ontology).

### A.2.8:2 - Problem

How can FPF represent a deontic commitment relation so that:

1. **The accountable subject is explicit** (role or role-enactor; not “the spec/interface/service”),
2. **Modality is explicit and lintable** (obligation / permission / prohibition / strength),
3. **Scope and validity window are explicit** (bounded context + time + conditions),
4. **The content is referenceable** via stable referent claim IDs (service clauses, gates, evidence targets, etc.),
5. **Adjudication hooks exist** when the binding is meant to be testable/auditable (links to evidence claims and carrier expectations),
6. **Conflicts can be represented** (without requiring this pattern to solve them).

### A.2.8:3 - Forces

| Force                          | Tension                                                                                                                                             |
| ------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------- |
| Minimality                     | The object must be small enough to use routinely, not a full legal-contract model.                                                                  |

| Layering discipline            | It must not collapse “law / gate / duty / evidence”; it should enable routing rather than replace it.                                               |
| Local meaning                  | Defaults should be bounded-context local; cross-context bindings must be explicit.                                                                  |
| Auditability                   | Some commitments are aspirational; others are auditable. The representation must support both, without implying auditability by default.            |
| Multi-level governance reality | People/orgs/states can issue incompatible commitments; the model must represent issuer/authority/priority without “solving politics” inside Part A. |

### A.2.8:4 - Solution

`U.Commitment` is the **kernel object** representing a **deontic commitment relation**: it links an accountable subject (role/role-enactor) to one or more referents via an explicit modality within an explicit scope/window, optionally with adjudication hooks.

This pattern defines:

* a **normative minimal structure** for `U.Commitment`,
* how `U.Commitment` relates to `U.ServiceClause`, `U.Work`, and evidence,
* how it is used as the canonical payload for **D-quadrant** claims (A.6.B),
* and what must be stated for a commitment to be considered **auditable**.

#### A.2.8:4.1 - Normative definition

A **`U.Commitment`** is a **governance object** representing a **deontic relation** that constrains an **accountable subject** (role or role-enactor) with respect to one or more **referents** under an explicit **modality** and explicit **scope/window**, optionally with explicit **adjudication hooks**.

Per A.7, a `U.Commitment` is **not** the text that states it: it is an object that is typically **instituted by** (and recorded via) one or more **speech acts and utterance descriptions** and may be carried by artifacts.

#### A.2.8:4.2 - Minimal structure (normative)

A conforming `U.Commitment` **SHALL** be representable by the following minimal record (field names are illustrative; the presence/meaning constraints are normative). **Required fields** are: `id`, `subject`, `modality`, `scope`, `validityWindow`, `referents`. `adjudication` and `source` are optional (but may become required by other patterns when auditability or authority must be made explicit).

```text
U.Commitment ::=
  {
    id: CommitmentId,                  // stable identifier; can align with D-* claim ID
    subject: CommitmentSubject,         // accountable role or role-enactor (not an episteme)
    owedTo: optional<set<CounterpartyRef>>, // who the commitment is owed to / intended beneficiary (optional; governance-facing, not required)
    modality: DeonticModalityToken,     // deontic modality (normalized; lintable)
    scope: U.ClaimScope,               // bounded context for applicability + non-temporal delimiters (same primitive as claim scopes; commitments are not epistemes)
    validityWindow: U.QualificationWindow, // Γ_time slice + conditions under which it applies / is in force
    referents: set<ReferentRef>,        // what is being bound (by reference, not paraphrase)
    adjudication: optional<AdjudicationHooks>, // evidence hooks if auditable
    source: optional<CommitmentSource>, // what instituted/authorized it (issuer + instituting act + utterance description), when provenance matters
    notes: optional<InformativeText>    // explicitly informative; not part of the binding
  }

CommitmentSubject ::=
  RoleRef | RoleAssignmentRef | PartyRef
  // At minimum: a RoleRef that denotes an accountable role kind in a bounded context.
  // If a concrete party/holder is known, prefer RoleAssignmentRef or PartyRef.
  // If multiple subjects are independently accountable, authors SHOULD model separate commitments (one per subject),
  // unless a joint obligation is explicitly modeled as a single PartyRef.

CounterpartyRef ::=
  PartyRef | RoleRef | RoleAssignmentRef
  // Optional “to whom”/beneficiary/counterparty handle. Keep minimal: do not treat it as a full legal-party model.

DeonticModalityToken ::=
  MUST | MUST_NOT | SHOULD | SHOULD_NOT | MAY
  // Interpreted as in RFC 8174 keyword discipline when used normatively.
  // **Normalization rule:** if authors use synonyms (e.g., SHALL, REQUIRED, RECOMMENDED, OPTIONAL),
  // they MUST be mapped to this normalized set for linting and comparison.
  //
  // **Normalization mapping (normative; illustrative table):**
  // - SHALL, REQUIRED        -> MUST
  // - SHALL NOT, PROHIBITED  -> MUST_NOT
  // - RECOMMENDED            -> SHOULD
  // - NOT RECOMMENDED        -> SHOULD_NOT
  // - OPTIONAL               -> MAY

ReferentRef ::=
  ClaimIdRef | ServiceClouseRef | MethodDescriptionRef | WorkRef
  // Prefer ClaimIdRef when a routed claim ID exists (L-*, A-*, D-*, E-*).
  // Use ServiceClouseRef when the commitment is about satisfying a promise-content clause (`U.ServiceClause`).
  // Use MethodDescriptionRef (preferred) when the commitment is about performing/avoiding a work-kind (work-to-be-done).
  // Use WorkRef only when the commitment is about an already executed/ongoing Work occurrence (rare).

ServiceClauseRef ::=
  ObjectIdRef
  // MUST resolve to a `U.ServiceClause` object (A.2.3). (Some chapters may call this a “service clause”.)

AdjudicationHooks ::=
  {
    evidenceRefs: set<ClaimIdRef>,      // typically E-* claim IDs
    carrierRefs: optional<set<CarrierClassRef>>,  // if evidence carriers are part of the hook
    evaluationNotes: optional<InformativeText>    // how adjudication is done; informative unless normed elsewhere
  }

DescriptionRef ::=
  ClaimIdRef | EpistemeRef
  // A pointer to an utterance description that states/records the commitment (e.g., spec clause, policy text).

SpeechActRef ::=
  ObjectIdRef
  // MUST resolve to a `U.SpeechAct` Work occurrence (A.2.9).

CommitmentSource ::=
  {
    issuer: optional<PartyRef>,         // who issued/authorized the commitment (can be distinct from subject)
    speechActRef: optional<SpeechActRef>, // instituting communicative act, when available
    descriptionRef: optional<DescriptionRef>, // where it is stated/recorded (utterance description)
    authorityClass: optional<AuthorityTag>, // e.g., policy, contract, statute, standard (informative tag)
    precedence: optional<PriorityTag>   // used for conflict handling elsewhere; not a truth claim
  }
```

**Normative constraints:**

* **(C1) Subject must be accountable.** `subject` **MUST** resolve to an accountable role/party; it **MUST NOT** be “the interface/spec/service/system” as an episteme.
* **(C2) Modality must be explicit and normalized.** `modality` **MUST** be present for normative commitments and **MUST** be normalized to `DeonticModalityToken`.
* **(C3) Scope + validity must be explicit.** `scope` and `validityWindow` **MUST** be present. Defaults are allowed only when an explicit context policy is cited as the source of those defaults (do not rely on “implied defaults”). `validityWindow` expresses *in-force* conditions; per-action admissibility gates belong in referenced `A-*` predicates.
* **(C4) Referents must be non-empty.** `referents` **MUST** contain at least one referent (what is being obligated/permitted/prohibited).
* **(C5) Referents must be by reference when possible.** If the bound content already exists as claim IDs, `referents` **SHOULD** cite those IDs rather than restating them.
* **(C6) Auditable commitments must have adjudication hooks.** If a commitment is intended to be audited/adjudicated by observation, `adjudication.evidenceRefs` **SHALL** include the evidence claim IDs (typically `E-*`) that carry the adjudication substrate.
* **(C7) Evidence belongs in adjudication by default.** If an `E-*` claim is referenced **only** to define *how to measure/verify* a commitment, it **SHALL** be listed in `adjudication.evidenceRefs` (not in `referents`). An `E-*` claim **MAY** appear in `referents` only when the commitment’s content is itself an evidence-producing/retaining duty (e.g., “MUST retain traces”).
* **(C8) Default auditability stance is explicit.** If `adjudication` is absent, the commitment SHALL be treated as **non-auditable by default** (aspirational / governance-only), unless another pattern or Context policy explicitly supplies adjudication hooks by reference.

#### A.2.8:4.3 - Interaction rules (normative)

1. **`U.ServiceClause` is promise content; `U.Commitment` is the governance relation.**
   A service promise clause (what is promised) is not, by itself, an accountable commitment. A `U.Commitment` makes an accountable subject responsible for providing/satisfying the service promise (or for satisfying other governance clauses).


2. **`U.Commitment` is not `U.Work`.**
   Work is execution; commitment is governance. A commitment may reference evidence targets, but it does not “contain” evidence.

3. **Commitments may reference admissibility predicates; they must not become predicates.**
   If compliance requires satisfying a gate predicate, the commitment should reference the gate (`A-*`) as a referent, rather than rewriting the predicate as prose inside the commitment.

4. **A `U.Commitment` is a governance object, not a law.**
   Commitments are not truth-conditional invariants. If something is intended to be an invariant, it belongs as law/definition (L), and a commitment can reference it.

5. **Lifecycle changes are explicit (no silent mutation).**
   When a commitment is updated, narrowed, broadened, superseded, or revoked, the change **SHOULD** be represented as a new `U.Commitment` (new ID) and an instituting `U.SpeechAct` (A.2.9) that references the affected commitment IDs (e.g., via `U.Commitment.source.speechActRef` and a status/supersession claim), rather than editing a published commitment in place without an auditable change record.

#### A.2.8:4.4 - Canonical use in boundary claim registers (recommended)

When using the A.6 stack, represent each **D-quadrant** atomic claim as a `U.Commitment` payload with:

* `id = D-*`,
* `subject = accountable role/party`,
* `modality = DeonticModalityToken` (normalized from RFC-keyword family usage),
* `referents = {ServiceClauseRef, MethodDescriptionRef, L-*, A-* … as needed}` (content/targets),
* `adjudication.evidenceRefs = {E-* …}` when the commitment is meant to be checkable.
 

### A.2.8:5 - Archetypal Grounding (Tell–Show–Show)

#### A.2.8:5.1 - Tell (universal rule)

A deontic statement becomes stable and reviewable when it is represented as a `U.Commitment` with an accountable subject, an explicit modality, explicit scope/window, referent claim IDs, and—if auditable—explicit evidence hooks.

#### A.2.8:5.2 - Show #1 (system archetype: incident response SLO discipline, post‑2015 SRE practice)

A production org states: “Severity‑1 incidents must be responded to within 4 hours.”

A routable commitment:

* `subject`: `RoleAssignmentRef(OpsTeam as ProviderRole)` (or at least `RoleRef(ProviderRole)`),
* `modality`: `MUST`,
* `scope`: bounded context `IncidentManagement`,
* `validityWindow`: `calendarYear2026` (or “while contract edition X is active”),
* `referents`: `{ServiceClauseRef(SVC-SLO-RESP-4H), A-SEV1-CLASS-1}`
   where `A-SEV1-CLASS-1` is the admissibility predicate for “counts as Sev‑1”.
* `adjudication.evidenceRefs`: `{E-SLO-RESP-1}`
   where `E-SLO-RESP-1` defines the measurement substrate and evidence carriers (tickets + timestamps + clock source).

This makes the statement auditable by construction and keeps “classification gate” separate from “duty”.

#### A.2.8:5.3 - Show #2 (episteme archetype: protocol specification with behavioural typing motif)

A protocol spec states: “Participants MUST follow the state machine; violations are rejected; traces are retained for audit.”

Model as:

* A set of `L-*` claims defining the state machine and safety/progress properties within the model,
* `A-*` claims defining what runtime checks count as “admissible trace”,
* `D-*` commitments instantiated as `U.Commitment` with:

  * `subject = RoleRef(ParticipantImplementer)`
  * `modality = MUST`
  * `referents = {L-STATE-MACHINE-1, A-TRACE-VALID-1, MethodDescriptionRef(TraceRetentionProcedure_v1)}`
  * `adjudication.evidenceRefs = {E-TRACE-LOG-1}`

This mirrors common post‑2015 “protocols as types” practice: semantics and progress live in the model; compliance is agent governance; evidence is trace-based.

### A.2.8:6 - Bias-Annotation

Lenses tested: **Gov**, **Arch**, **Onto/Epist**, **Prag**, **Did**. Scope: **Kernel universal** (any place FPF needs deontic binding).

* **Gov bias:** prioritizes accountable subjects and adjudication hooks; may increase authoring overhead.
* **Arch bias:** pushes reference-by-ID and explicit scope/window to preserve evolvability and reduce drift.
* **Onto/Epist bias:** enforces “descriptions don’t promise”; commitments bind agents/roles.
* **Prag bias:** aligns with common spec-language practice (RFC keywords) but makes the structure explicit.
* **Did bias:** favors a small record that can be taught and linted.

### A.2.8:7 - Conformance Checklist (normative)

1. **CC‑A.2.8‑1 (Accountable subject).** A normative `U.Commitment` **MUST** name an accountable `subject` (role/role-enactor/party) and **MUST NOT** use an episteme (spec/interface/document) as subject.

2. **CC‑A.2.8‑2 (Explicit modality).** A normative `U.Commitment` **MUST** specify `modality` as `DeonticModalityToken` (with any RFC-keyword synonyms normalized to it).

3. **CC‑A.2.8‑3 (Scope & validity explicit).** A normative `U.Commitment` **MUST** specify `scope` (`U.ClaimScope`) and `validityWindow` (`U.QualificationWindow`), or explicitly cite the context policy that supplies defaults (do not rely on “implied defaults”).

4. **CC‑A.2.8‑4 (Referents present and by ID).** `referents` **MUST** be non‑empty. If the bound content exists as claim IDs, the commitment **SHOULD** reference those IDs in `referents` rather than restating their content.

5. **CC‑A.2.8‑5 (Auditable commitments have hooks).** If the commitment is intended to be auditable, it **SHALL** include `adjudication.evidenceRefs` referencing the evidence claims (typically `E-*`) that make adjudication possible.
6. **CC‑A.2.8‑6 (Evidence separation).** If an `E-*` claim is referenced only for measurement/verification, it **SHALL** appear in `adjudication.evidenceRefs` (not in `referents`).

### A.2.8:8 - Common Anti-Patterns and How to Avoid Them

| Anti-pattern                                        | Why it fails                                               | Repair                                                                                |
| --------------------------------------------------- | ---------------------------------------------------------- | ------------------------------------------------------------------------------------- |
| **Episteme-as-subject** (“the API SHALL…”)          | assigns agency to descriptions                             | use an accountable role/party as `subject`; keep the spec as `source.descriptionRef`  |
| **Missing scope/window**                            | commitments become unreviewable (“always/never” ambiguity) | declare `scope` + `validityWindow`; if global, say so explicitly via a policy/default |
| **Paraphrase drift**                                | drift across faces and docs                                | reference via `referents` using claim IDs; avoid restating the same constraint        |
| **Auditable rhetoric** (“guaranteed”) without hooks | not adjudicable                                            | add `adjudication.evidenceRefs` pointing to `E-*` claims and carrier expectations     |
| **Gate-as-duty**                                    | confuses admissibility with obligation                     | put predicate in `A-*`; make commitment reference it (`D→A`)                          |

### A.2.8:9 - Consequences

**Benefits**

* Makes deontic statements **first-class and lintable** (subject/modality/scope/referents/hooks).
* Enables clean integration with boundary routing (A.6.B) and contract unpacking (A.6.C) without embedding ontology in naming patterns.
* Improves auditability by making evidence expectations explicit *only when intended*.

**Trade-offs / mitigations**

* Adds structure to authoring; mitigated by allowing conceptual evidence hooks and default scope policies.
* Does not resolve conflicts between commitments; mitigated by capturing `source/precedence` tags and delegating resolution to governance patterns (Part D) and context policy.

### A.2.8:10 - Rationale

The triad “promise / utterance / commitment” is useful for language discipline, but deontic ontology should not be anchored in a naming-focused pattern. A kernel object:

* stabilizes what a “commitment” structurally is,
* ensures “MUST/SHALL” talk is representable without category mistakes,
* and provides the missing bridge between governance claims and adjudication (via explicit hooks), which is essential for boundary engineering and for later ethics/governance work.

### A.2.8:11 - SoTA-Echoing (informative; post‑2015 alignment)

> **Informative.** Alignment notes; not normative requirements.

* **BCP 14 (RFC 2119 + RFC 8174) / modern spec-language discipline (2017+).** Treating modality tokens as a controlled family is standard; `U.Commitment.modality` makes this family explicit and lintable.
* **Policy-as-code ecosystems (2016+).** Modern governance stacks often encode gates as code (e.g., Kubernetes admission controls, OPA/Rego-style policy evaluation) and obligations as process controls; the `U.Commitment` structure helps keep “gate predicates” separate from “actor duties”, while still linking them by reference.
* **ODRL-style duty/permission/prohibition modeling (W3C ODRL 2.2, 2018).** The minimal “subject + modality + constraint/window + target” shape is widely used; `U.Commitment` adopts the kernel of that idea while keeping FPF’s boundary routing and evidence discipline.
* **Trace-based compliance and audit (2018+ supply-chain / reproducibility practice).** “Compliance is evidenced by artifacts” is mainstream; `adjudication.evidenceRefs` captures this without turning evidence into semantics.
* **Supply-chain attestations (2021+).** Attestation-oriented schemes (e.g., SLSA-style provenance, transparency logs) operationalize “claims + evidence carriers”; `adjudication.evidenceRefs` is the bridge point without collapsing evidence into truth.

### A.2.8:12 - Relations

**Uses / builds on**

* A.2.1 for identifying accountable roles vs role-enactors (role assignments).
* A.2.6 for expressing scope and time/window (`U.ClaimScope`, `U.QualificationWindow`).
* A.7 for keeping “binding” distinct from “utterance” and from “carriers”.

**Used by**

* A.6.B (Quadrant D) as the canonical payload shape for deontic statements.
* A.6.C (Contract Unpacking) as the formal anchor for the “Commitment” component of the bundle.
* Part D governance/ethics patterns (future work) for expressing layered, conflicting, multi-authority commitments.

**Coordinates with**

* A.2.3 (`U.ServiceClause`): services are promise clauses; commitments bind accountable subjects to those clauses.
* **A.2.9 (`U.SpeechAct`)**: `U.Commitment.source.speechActRef` points to the instituting communicative work occurrence when provenance matters.
* A.15.1 (`U.Work`) and evidence patterns: adjudication hooks refer to evidence in work, not to text.

### A.2.8:End


## A.2.9 — `U.SpeechAct` (Communicative Work Object)

> **Type:** Definitional (D)
> **Status:** Stable
> **Normativity:** Normative (unless explicitly marked informative)
> **Placement:** Part A → **A.2 Roles & Agency Kernel**
> **Refines:** A.2 (Role Taxonomy)
> **Builds on:** A.2.1 (RoleAssignment), A.2.6 (`Γ_time` / windows), A.7 (Object≠Description≠Carrier), A.10 (SCR/RSCR carrier discipline), A.15.1 (`U.Work`)
> **Purpose (one line):** Provide a minimal, lintable kernel object for **communicative enactments** (approvals, authorizations, revocations, notices, declarations, publications) as **`U.Work`**, explicitly separating the **act** from its **utterance descriptions** and **evidence carriers**, so governance and gating can cite `SpeechActRef` without “contract soup” or episteme‑as‑agent mistakes.

> FPF already treats communicative acts as observable events used in role-state checklists and grounding (“presence of act: AuthorizationSpeechAct exists…”, and `U.SpeechAct` is listed as an observable basis for state assertions).
> The spec’s micro-examples and conformance gates distinguish **communicative Work** (“performed a SpeechAct”) from **operational Work** (“executed Work”) while keeping both inside `U.Work` (cf. CC‑A15‑10 GateSplit).
> F.18 currently frames `U.SpeechAct` as the “utterance” label in the promise/utterance/commitment triad; A.2.9 keeps that as **naming intuition** while putting the ontology and conformance discipline in Part A where it can be linted and reused.

### A.2.9:1 — Problem frame

FPF repeatedly needs to reference “someone said/did the approving/authorizing/declaring thing”:

* Role eligibility and enactability checklists often depend on the **presence of an approval/authorization act** within a freshness window.
* Governance patterns and boundary writing (A.6 stack) need **provenance**: “this obligation/commitment/permission was instituted by *that* act”.
* Operational patterns need auditable **notices** (“depletion notice”, “override invoked”) whose existence and timing matter.

Without a **first‑class kernel object** for such communicative events, authors tend to:

* attribute agency to descriptions (“the spec approves…”, “the interface guarantees…”),
* collapse “utterance text” and “speech act event”,
* leave provenance dangling as “if modeled”,
* encode gates as prose obligations, or treat obligations as gates.

This pattern makes “speech act” an explicit, queryable **Work‑kind** with clear boundaries to `U.Commitment` and to utterance surfaces.

### A.2.9:2 — Problem

How can FPF represent communicative enactments so that:

1. **Agency is explicit:** a concrete accountable subject performs the act (role/role‑enactor), not a document/spec/interface.
2. **The act is locatable in time:** the act has an explicit Window (and thus freshness can be evaluated).
3. **The act is locatable in meaning:** the act is recognized inside a declared **bounded context** (the `U.Work` judgement context), not via `U.ClaimScope` (which expresses applicability of claims/commitments, not the judgement context for Work occurrences).
4. **The act is auditable:** it has at least one declared utterance description and/or evidence carrier when used for gating or governance.
5. **Institutional effects are linkable:** the act can institute (or update/revoke) commitments, role assignments, statuses, etc., by reference.
6. **Ambiguity is handled pragmatically:** the model supports multi‑function / multi‑party communication without requiring full linguistic pragmatics.

### A.2.9:3 — Forces

| Force                  | Tension                                                                                                                 |
| ---------------------- | ----------------------------------------------------------------------------------------------------------------------- |
| Minimality             | Needs to be light enough for routine modeling and linting; not a full pragmatics or legal-contract system.              |
| Auditability           | If used as a gate, it must be evidence-backed; but not all communicative acts are equally observable or retainable.     |
| Context locality       | Meaning and “institutional force” are context-local; cross-context reuse must remain explicit (Bridge-only discipline). |
| Multi-party reality    | Many real boundaries are multiparty (protocols, organizations); dyadic “speaker-hearer” is too narrow.                  |
| Multi-function reality | One utterance can carry multiple recognizable functions; “one act = one force” is often false.                          |
| Separation discipline  | Must preserve A.7 splits: **act object** ≠ **utterance description** ≠ **carrier/traces**.                              |

### A.2.9:4 — Solution

`U.SpeechAct` is a **kernel Work object**: a recorded communicative enactment performed by an accountable role‑enactor within a bounded context, optionally addressed to others, that is **recognized** (in that context) as updating an information and/or governance state. The act is **not** the utterance text; it points to utterance descriptions and evidence carriers.

#### A.2.9:4.1 — Normative definition

A **`U.SpeechAct`** is a **`U.Work`** occurrence whose primary (intended) effect is **communicative**: it places an utterance into a context in a way that is recognized by that context’s institutional semantics (policies, procedures, protocol rules) as potentially:

* asserting/informing,
* requesting/directing,
* promising/committing (as an instituting act),
* declaring/authorizing/revoking (status-changing acts),
* notifying (event announcement relevant for downstream work).

Per A.7, `U.SpeechAct` is an **object/event**; its **utterance descriptions** are descriptions (epistemes/spec clauses/messages‑as‑content), and its **carriers** are artifacts/traces that support observation and audit. *(Note: “Surface” is reserved for MVPK publication/interoperability surfaces; do not use it here.)*

Whether a given `actType` institutes commitments/permissions/status changes is **entirely context‑policy dependent**. Absent an explicit policy, treat a `U.SpeechAct` as a communicative Work occurrence with observable provenance only; do not infer deontic bindings from the act by default.

#### A.2.9:4.2 — Minimal structure (normative)

A conforming `U.SpeechAct` **SHALL** be representable by the following minimal record (field names are illustrative; the constraints are normative):

```
U.SpeechAct <: U.Work

Invariant: U.Work.kind = Communicative

U.SpeechAct ::=
  U.Work
  & {
      actTypes: set<SpeechActTypeRef>,               // ≥1 act types (supports multi-function)
      addressedTo: optional<set<AddresseeRef>>,      // optional: who is addressed / audience
      utteranceRefs: optional<set<DescriptionRef>>,  // where the utterance content is stated/recorded (A.7: Description)
      carrierRefs: optional<set<CarrierRef>>,        // evidence carriers/traces (A.7: Carrier; use A.10 when evidentiary)
      institutes: optional<InstitutedEffects>,       // references to objects/claims instituted/updated by this act
      notes: optional<InformativeText>               // explicitly informative
    }

DescriptionRef ::=
  ClaimIdRef | EpistemeRef
  // Pointer to an utterance description (e.g., spec clause claim ID, a policy episteme, a message-content episteme).

SpeechActTypeRef ::=
  ContextLocalTokenRef
  // Must be defined/recognized in the Work’s judgement context (bounded context).

AddresseeRef ::=
  PartyRef | RoleRef | RoleAssignmentRef

InstitutedEffects ::=
  {
    commitments: optional<set<CommitmentIdRef>>,
    roleAssignments: optional<set<RoleAssignmentRef>>,
    statusClaims: optional<set<ClaimIdRef>>,         // e.g., “StandardStatus=Approved” if modeled as claims
    other: optional<set<ObjectIdRef>>
  }
```

**Normative constraints:**

* **(SA‑C0) Work conformance applies.** Because `U.SpeechAct <: U.Work`, a speech‑act record **MUST** satisfy `U.Work` conformance (A.15.1), including the required anchors (`isExecutionOf`, `performedBy`, `executedWithin`, `window`, and state‑plane / judgement‑context anchoring). A speech act **MUST** have at least one `affected` referent (the thing it is *about/updates*), even if it is purely governance‑state.
* **(SA‑C1) PerformedBy must be an accountable actor.** `performedBy` **MUST** resolve to a `RoleAssignmentRef` whose holder is an accountable system/party in the named scope. It **MUST NOT** be a spec/interface/document as an episteme.
* **(SA‑C2) ActTypes are required and context-local.** `actTypes` **MUST** contain at least one `SpeechActTypeRef` recognized in the Work’s judgement context (local meaning). Free‑text verbs are nonconformant unless registered as a context token.
* **(SA‑C3) Time honesty.** `window` **MUST** be explicit (or inherited from the parent `U.Work` record) so freshness rules can be evaluated.
* **(SA‑C4) If used for gating/audit, it must be observable.** If a speech act is used as a checklist criterion, guard condition, or provenance hook for a `U.Commitment`, the model **SHALL** include at least one observable handle: `utteranceRefs` and/or `carrierRefs`. When the act is used as evidence, at least one carrier reference **SHOULD** be SCR/RSCR‑resolvable per A.10.
* **(SA‑C5) Institutional effects are references, not paraphrases.** When the act is intended to institute/update commitments, role assignments, or statuses, `institutes.*` **SHOULD** reference the corresponding object IDs/claim IDs rather than restating content.
* **(SA‑C6) Cross-context use is Bridge-only.** If a `SpeechActRef` is used for checking/gating/provenance in a **different bounded context** than the act’s judgement context, the referencing object **MUST** satisfy the spec’s cross-context discipline by citing an explicit Bridge/policy that licenses the interpretation (and surfacing congruence vs loss where applicable), rather than assuming equivalence by label.

#### A.2.9:4.3 — `SpeechActRef` discipline (normative)

A **`SpeechActRef`** is a reference to `U.SpeechAct.id`.

* If another object (e.g., `U.Commitment.source.speechActRef`) cites a `SpeechActRef`, the referenced `U.SpeechAct` **MUST** satisfy **SA‑C0…SA‑C4** (and SA‑C6 when used cross‑context).
* A `SpeechActRef` **MUST NOT** be replaced by an `EpistemeRef` (“see the document”) when provenance is needed; the episteme is an utterance description, not the act.
* If a system cannot record a full `U.SpeechAct`, it may record a **stub** that still satisfies **SA‑C0…SA‑C4** (minimal `actTypes`, performer, judgement context, window, `affected`, plus at least one observable handle). When a required `U.Work` anchor is unknown, the stub **MUST** use an explicit placeholder (e.g., an “AdHocCommunication” MethodDescription) rather than omitting the field.

#### A.2.9:4.4 — Separation rules with `U.Commitment` and `U.ServiceClause` (normative)

1. **Speech act is not the deontic binding.**
   A speech act may **institute** a `U.Commitment`, but the deontic relation itself is the `U.Commitment` object (A.2.8). Do not encode obligations/permissions inside `U.SpeechAct` as prose; instead, create/point to `U.Commitment` IDs in `institutes.commitments`.

2. **Speech act is not the service promise clause.**
   `U.ServiceClause` / service clauses are promise content; a speech act may be the act of offering/issuing that promise, but the promise content lives in the service/service clause objects and is referenced from the resulting commitments.

3. **Speech act is not the carrier.**
   A “signed approval PDF”, “ticket record”, “Slack message”, or “API call log” is a carrier (and may carry an episteme as utterance content); the speech act is the Work occurrence that produced/issued it.

4. **Publishing a spec is not a commitment by default.**
   **Default interpretation rule (normative).** A conformant model/interpreter **MUST NOT** infer `U.Commitment` objects solely from `Publish`/`Approve` speech acts. Publication MAY institute publication/status claims (e.g., “Published”, “Approved”, “Deprecated”), but any obligations/permissions on implementers/operators/providers **MUST** be modeled explicitly as `U.Commitment` objects (A.2.8). If a Context defines a policy that maps publication acts to commitment-instituting effects (e.g., a named `SpecPublicationPolicy@Context`), that policy **MUST** be named and cited where the implication is used.

#### A.2.9:4.5 — Multi-function and multi-party support (normative)

* **Multi-function:** `actTypes` is a **set**. If one utterance performs multiple recognizable acts (e.g., “approve + instruct + warn”), the model may either:

   * represent one `U.SpeechAct` with multiple `actTypes` entries, or
   * represent multiple `U.SpeechAct` records that share the same `carrierRefs/utteranceRefs`.
   In either case, institutional effects must remain referenceable (SA‑C5).

* **Multi-party:** `addressedTo` is a set and may include roles/parties/assignments. If addressees matter for validity (e.g., “approval by CAB chair to deployment bot”), they should be explicit.

### A.2.9:5 — Archetypal Grounding (Tell–Show–Show)

#### A.2.9:5.1 — Tell (universal rule)

When governance or gating depends on “someone said/did X”, model **that saying/doing** as a `U.SpeechAct` (a Work occurrence), and keep the utterance text and carriers separate. If the saying/doing creates obligations, model those obligations as `U.Commitment` objects instituted by the speech act.

#### A.2.9:5.2 — Show #1 (system archetype: change-control approval gates a deployment)

**Situation (messy prose):**
“Change is approved, so the pipeline may deploy.”

**Conformant modeling sketch:**

* `U.SpeechAct SA-Approve-4711`

  * `actTypes = {SpeechActTypeRef(Approval@ChangeControl)}`
  * `performedBy = RoleAssignmentRef(CAB_Chair as ApproverRole@ChangeControl)`
  * `isExecutionOf = MethodDescriptionRef(ChangeApprovalProcedure_v3)`
  * `executedWithin = ChangeControlBoardSystem`
  * `window = [t,t]`
  * `affected = {ChangeRequestId(4711), WorkRef(Deploy-4711)}`
  * `utteranceRefs = {EpistemeRef(ChangeTicket#4711)}`
  * `carrierRefs = {CarrierRef(TicketSystemRecord#4711)}`
  * `institutes.commitments = {CommitmentIdRef(D-Deploy-Authorized)}`

  * `modality = MAY` (permission to enact)
  * `referents = {A-Gate-Deploy-4711}`
  * `source.speechActRef = SA-Approve-4711`

* Gate predicate `A-Gate-Deploy-4711` may include:
  `exists SpeechAct(type=Approval, affected includes ChangeRequestId(4711), performedBy role=ApproverRole, within 90d)`.

This preserves:

* act vs text vs carrier,
* explicit performer,
* time window for freshness,
* explicit provenance from commitment back to the instituting act.

#### A.2.9:5.3 — Show #2 (episteme archetype: publishing a spec edition without making the spec an agent)

**Situation (anti-pattern):**
“The interface spec declares MUST/SHALL requirements.”

**Conformant modeling sketch:**

* `U.SpeechAct SA-Publish-API-v12`

  * `actTypes = {SpeechActTypeRef(Publish@APISpecContext), SpeechActTypeRef(DeclareNorms@APISpecContext)}`
  * `performedBy = RoleAssignmentRef(StandardsEditor as PublisherRole@APISpecContext)`
  * `isExecutionOf = MethodDescriptionRef(SpecReleaseProcedure_v12)`
  * `executedWithin = SpecPublicationSystem`
  * `window = [t,t]`
  * `affected = {EpistemeRef(APISpec_v12)}`
  * `utteranceRefs = {EpistemeRef(APISpec_v12)}`
  * `carrierRefs = {CarrierRef(GitTag:v12), CarrierRef(SignedReleaseArtifact:v12)}`
  * `institutes.statusClaims = {ClaimIdRef(D-StdStatus-APISpec_v12-Published)}` (if modeled)

Norms live in the **published utterance surfaces** (spec clauses as routed claims), but the **act of publication** is a speech act performed by an accountable role. This avoids “the spec promises/commits” category errors while preserving auditability.

### A.2.9:6 — Bias-Annotation

Lenses tested: **Gov**, **Arch**, **Onto/Epist**, **Prag**, **Did**. Scope: **Kernel universal** for speech-act usage that matters for governance, eligibility, gating, provenance, and protocol boundaries.

* **Gov bias:** favors explicit accountable performers and auditable records; increases clarity but adds modeling overhead.
* **Arch bias:** optimizes evolvability by keeping institutional effects referenceable rather than embedded in prose.
* **Onto/Epist bias:** enforces act≠utterance≠carrier and prevents episteme-as-agent metaphors.
* **Prag bias:** models only what is needed for decisions/audit (not full intention/sincerity/perlocutionary psychology).
* **Did bias:** keeps the record minimal and queryable for state checklists and boundary reviews.

### A.2.9:7 — Conformance Checklist (normative)

1. **CC‑A.2.9‑1 (Accountable performer).** A normative `U.SpeechAct` record **MUST** identify `performedBy` as an accountable `RoleAssignmentRef` and **MUST NOT** use an episteme (spec/interface/document) as performer.
2. **CC‑A.2.9‑2 (ActTypes declared).** A `U.SpeechAct` record **MUST** include at least one `SpeechActTypeRef` recognized in its judgement context.
3. **CC‑A.2.9‑3 (Window explicit).** A `U.SpeechAct` record **MUST** have an explicit `window` (or inherit a window from its parent work record) so freshness and gating can be evaluated.
4. **CC‑A.2.9‑4 (Observable when used for gating/provenance).** If a speech act is cited by a checklist/guard or by `U.Commitment.source.speechActRef`, it **SHALL** have at least one `utteranceRef` or `carrierRef` that supports observation/audit in the given context; evidence‑critical uses **SHOULD** anchor at least one carrier via SCR/RSCR per A.10.
5. **CC‑A.2.9‑5 (Effects by reference).** If the act is intended to institute/update commitments/roles/statuses, those effects **SHOULD** be referenced in `institutes.*` by stable IDs.
6. **CC‑A.2.9‑6 (Bridge-only cross-context use).** If a `SpeechActRef` is interpreted for gating/provenance in a different bounded context than the act’s judgement context, the referencing object **MUST** cite the Bridge/policy that licenses that cross-context interpretation (no “same label implies same force”).


### A.2.9:8 — Common Anti-Patterns and How to Avoid Them

| Anti-pattern                                                              | Why it fails                         | Repair                                                                                   |
| ------------------------------------------------------------------------- | ------------------------------------ | ---------------------------------------------------------------------------------------- |
| **Episteme-as-actor** (“the spec approves/declares”)                      | assigns agency to descriptions       | represent the publishing/approving act as `U.SpeechAct(performedBy=RoleAssignment)`      |
| **Carrier-as-act** (“the signed PDF is the approval”)                     | conflates carrier with act           | model `U.SpeechAct` and point to PDF as `carrier`/`utteranceSurface`                     |
| **Free-text type** (“type=‘approved-ish’”)                                | not lintable; drifts across faces    | register `SpeechActTypeRef` in the context and use it                                    |
| **Act carries obligations** (obligations embedded as prose in speech act) | collapses act and deontic binding    | model obligations as `U.Commitment` objects instituted by the act                        |
| **Gating without window**                                                 | cannot evaluate freshness            | add explicit `window` and reference it in the guard/checklist                            |
| **Hidden multi-act** (one event silently creates multiple commitments)    | loses traceability; creates disputes | represent multi-function via `actTypes` set or multiple speech acts sharing the same carrier |

### A.2.9:9 — Consequences

**Benefits**

* Makes approvals/authorizations/notices **first-class and queryable**, enabling clean RSG checklists and guard rules.
* Provides stable provenance: commitments and status transitions can cite the **instituting act** explicitly.
* Prevents recurring category errors: “documents promise”, “interfaces commit”, “logs prove”.

**Trade-offs / mitigations**

* Requires recording a small structured object for communicative events; mitigated by allowing minimal stubs that still satisfy CC‑A.2.9‑1…4.
* Requires context-local `SpeechActTypeRef` registration; mitigated by starting with a small set (Approve, Revoke, Publish, Notify, Authorize) and extending as needed.

### A.2.9:10 — Rationale

FPF already relies on communicative acts (approvals, notices, overrides) as operationally meaningful events, but without a kernel object they blur into examples, naming choices, or prose. A.2.9 anchors speech acts where they belong: as a **Work-kind** with explicit performer, scope, and time, and with disciplined links to utterance surfaces, carriers, and deontic bindings (`U.Commitment`).

This also improves modularity:

* **F.18** can remain a **lexical anchor** for naming (why “SpeechAct/utterance” as a label family is useful),
* while **A.2.9** carries the ontology and conformance discipline for how speech acts behave as objects and how they connect to commitments and evidence.

### A.2.9:11 — SoTA‑Echoing (informative; post‑2015 alignment)

> **Informative.** Alignment notes; not normative requirements.

* **Adopt — ISO 24617‑2:2020 / multi-dimensional communicative functions.** Modern dialogue‑act standards treat communicative behavior as potentially multi‑functional. A.2.9 mirrors this by allowing `actTypes` to be a **set** and by supporting shared carriers across multiple acts.
* **Adapt — commitment-based semantics for communication (multi-agent/protocol practice, 2015+).** A pragmatic way to avoid mental-state modeling is to track communication by its **social/institutional effects**, especially on commitments and protocol states. A.2.9 reflects this via `institutes.commitments` and explicit links to `U.Commitment` without modeling sincerity or intention.
* **Adopt (warning) — illocutionary pluralism in multiparty discourse (2015+).** One utterance commonly performs multiple recognizable functions. A.2.9 avoids the “single force” trap by permitting multi‑type acts and/or multiple acts sharing the same utterance and carriers.

### A.2.9:12 — Relations

**Uses / builds on**

* Uses **A.15.1 (`U.Work`)** for the event/work backbone (performedBy + window + stance).
* Uses **A.7** for the strict act≠description≠carrier split.
* Coordinates with **A.2.6** for scope/window discipline.

**Used by**

* **A.2.8 (`U.Commitment`)** as a concrete target for `source.speechActRef` provenance.
* **A.2.5 (RSG checklists/guards)** when “presence of authorization/approval act” is a criterion.
* **A.6.C (Contract unpacking)** as the “utterance/instituting act” hook that prevents episteme-as-agent claims and improves provenance.

### A.2.9:End
 
## A.3 - Transformer Constitution (Quartet)

### A.3:1 - Intent

Establish a single, substrate‑neutral way to say **who acts**, **under which role**, **according to which description**, **by which capability**, and **what actually happened**—without “self‑magic” and without blurring design‑time and run‑time. The pattern fixes the **Transformer Quartet** so all kernel and Γ‑patterns reuse the *same four anchors*. It builds directly on **Holon‑Role Duality (A.2)** and **Temporal Duality (A.4)** and is guarded by **Strict Distinction (A.7)** and **Evidence Graph Referring (A.10)**.

### A.3:2 - Context

* **Holonic substrate.** FPF separates *what things are* (Holon → {System, Episteme, …}) from *what they are being right now* via **roles**. Only **systems** can bear **behavioural** roles and execute methods/work; epistemes are changed **via their symbol carriers**.
* **Role as mask; behaviour as method/work.** A role is a **mask**, not behaviour; behaviour is a **Method** (order‑sensitive capability) that may be executed as **Work** (dated occurrence).
* **Design‑time vs run‑time.** A holon’s states belong to disjoint scopes **Tᴰ** and **Tᴿ**; transitions are physically grounded by a system bearing **TransformerRole**.
* **Evidence & carriers.** Claims about outcomes must anchor to **carriers** (SCR/RSCR) and to an **external** evidencing transformer.

### A.3:3 - Problem

Legacy phrasing (“actor / process / blueprint”) causes recurrent failures:

1. **Self‑magic:** “the system configures itself” (no external acting side, causality lost).
2. **Plan = event:** blueprint/algorithm reported as if execution happened.
3. **Capability = result:** possession of a method counted as evidence of work.
4. **Episteme as doer:** documents/models treated as actors.
5. **Scope leak:** design‑time and run‑time mixed; run traces lack carriers/method ties.
   A.2/A.4/A.7/A.10 collectively forbid these, but A.3 must give the **canonical quartet** that authors can apply consistently.

### A.3:4 - Forces

| Force                       | Tension                                                                                     |
| --------------------------- | ------------------------------------------------------------------------------------------- |
| **Identity vs behaviour**   | Keep holon identity stable while roles/behaviours change.                                   |
| **Simplicity vs precision** | Managers want one “process” box; kernel must keep **MethodDescription / Method / Work** distinct.  |
| **Universality vs idioms**  | Pumps, proofs, and data‑pipelines must read the same, yet allow domain names.               |
| **Design vs run**           | No overlap of **Tᴰ** and **Tᴿ**; bridges explicit and causal.                               |
| **Evidence vs mereology**   | Provenance edges (EPV‑DAG) must never turn into part‑whole edges.                           |

### A.3:5 - Solution — The Transformer Quartet

A.3 defines four anchors, tied together by **Role Assignment (`U.RoleAssignment`)** and aligned with **Temporal Duality**.

#### A.3:5.1 - The four anchors (terms & types)

1. **Acting side:** a **system bearing TransformerRole** — the only holon kind allowed to enact transformations (behavioural role). *Canonical phrase:* **“system bearing TransformerRole”**. *Local shorthand:* after explicit binding in the **same subsection**, you MAY write **“Transformer”** to denote that same system; re‑bind on context change and **do not** use shorthand where the domain already has a conflicting “transformer” term.

2. **MethodDescription (design‑time description):** protocol / algorithm / SOP / script — all are **idioms of MethodDescription**; they live in **Tᴰ** and are **epistemes** with carriers (SCR/RSCR).

3. **Method (design‑time capability):** order‑sensitive composition the system *can* enact at run‑time (Γ\_method); it is **not** an occurrence.

4. **Work (run‑time occurrence):** dated execution producing state change and consuming resources (Γ\_work); every Work **isExecutionOf** exactly one MethodDescription version and is **performedBy** exactly one performer (possibly a collective system).

> **Safe memory line:** *MethodDescription → (describes) Method → (executed as) Work.*
> Roles are **masks** (A.2/A.7); methods/work are **behaviour**.

#### A.3:5.2 - Contextual Role Assignmnent (`U.RoleAssignment`) for transformations

Use the universal assignment to state **who plays which role where and when**:

```
U.RoleAssignment(
  holder  : U.System,          -- the acting system (bearer)
  role    : U.TransformerRole, -- behavioural role
  context : U.BoundedContext,  -- semantic boundary
  timespan?: Interval          -- optional validity window
)
```

* A role is **local to context** and **time‑indexed**.
* The same system may bear multiple roles **if** the context allows compatibility.
* For epistemes, the target of change is their **symbol carriers**; the acting side is still a **system**.

#### A.3:5.3 - Boundary & externality

Every transformation is modelled with **two sides** and an explicit **U.Interaction** boundary: **acting** (system bearing TransformerRole) and **target** (system being transformed, or the **carrier** of an episteme). There is **no self‑doing**; “self‑like” stories are handled by the **reflexive split** (regulator vs regulated subsystems) or by promoting a meta‑holon and keeping evidence external (A.12).

#### A.3:5.4 - Temporal alignment (A.4 bridge)

* **MethodDescription** lives in **Tᴰ**;
* **Method** is defined at design-time and **executed as `U.Work` at run-time by a `U.System` with a valid `U.RoleAssignment` (window-aligned) and a live **StateAssertion** for an **enactable** RSG state**;
* **Work** lives in **Tᴿ**;
* transitions **Tᴰ → Tᴿ** and **Tᴿ → Tᴰ** are **grounded** by executions of appropriate methods by an **external** transformer (e.g., fabrication or observation).

#### A.3:5.5 - Evidence Graph Referring

Each Work anchors to **carriers** and to the **MethodDescription** it instantiates; evidencing transformers are **external** (no self‑evidence). This sits in the **EPV‑DAG** and never in mereology.

#### A.3:5.6 - Didactic dictionary (safe mappings)

* “Process / Workflow / SOP / Algorithm” ⇒ **MethodDescription** (design‑time description).
* “Operation / Job / Run / Performance” ⇒ **Work** (run‑time occurrence).
* “Function (equipment spec)” ⇒ **Method** (or MethodDescription if purely textual).
* “Creator” (legacy) ⇒ **Transformer** (shorthand for **system bearing TransformerRole** after local binding).

### A.3:6 - Illustrative scenarios (substrate‑neutral)

#### A.3:6.1 - Physical system — Cooling loop
`PumpUnit#3` (**system bearing TransformerRole**) executes `ChannelFluid` (**Method**) as per `centrifugal_pump_curve.ld` (**MethodDescription**), producing `run‑2025‑08‑08‑T14:03` (**Work**, 3.6 kWh; ΔT=6 K). Evidence goes to carriers in SCR; resource spend goes to Γ\_work.

#### A.3:6.2 - Epistemic change — Proof revision
`LeanServer` (**system bearing TransformerRole**) edits `proof_tactic.lean` (carrier) per MethodDescription; `lemma‑42‑check‑2025‑08‑08` is **Work**; the **episteme** (theorem) changes through its carriers; evidence is attributed to the external transformer.

#### A.3:6.3 - Reflexive maintenance — “calibrates itself”
Split into **Regulator** (calibration module, acting side) and **Regulated** (sensor suite, target) with an interaction boundary; credit evidence to the regulator; no self‑evidence.

### A.3:7 - Conformance Checklist (normative)

**CC‑A3‑0 - U.RoleAssgnment presence.**
Every claim that a holon “performs a transformation” MUST be backed by at least one **RoleAssignment** triple:
`U.RoleAssignment(holder: U.Holon, role: U.Role=TransformerRole, context: U.BoundedContext, timespan?)`.
This is the canonical way to say *who acts, in which role, where (semantically), and when*. See **A.2.1** for the universal **`U.RoleAssignment`** Standard and its invariants.

**CC‑A3‑1 - External transformer discipline.**
The **bearer** of `TransformerRole` MUST NOT be the same model instance as the **object‑under‑change** within the same assignment. Self-modification is modelled via two **`U.RoleAssignment`s** (same holder playing two roles) or via an explicit controller–plant split. This upholds **Agent Externalization** (A.12).

**CC‑A3‑2 - Design–Run separation.**
`U.MethodDescription` (recipe, definition) is a **design‑time** artefact; `U.Method` (mask‑of‑work) and `U.Work` (executed work) are **run‑time**. It is non‑conformant to mutate a `MethodDescription` inside a `Work` log or to treat a `Work` as a `MethodDescription`. This enforces the kernel’s **Temporal Duality** (A.4) and the A.15 alignment.

**CC‑A3‑3 - Boundary‑crossing evidence.**
A conformant transformation that changes a system’s state MUST reference the **boundary effects** it induces: interactions, flows, or state transitions attach to the target system’s boundary (per Γ‑defaults for additive, min/AND/OR folds). Conservation‑class effects MUST satisfy B‑invariants (e.g., **B‑1 Conservation**).

**CC‑A3‑4 - Method ←→ Work traceability.**
Every `U.Work` MUST (i) name the `U.Method` it instantiates and (ii) trace the `U.MethodDescription` it claims to follow (versioned). If a deviation occurs, it MUST be logged as a **policy override** or **exception path**; silent drift is non‑conformant. (A.15 guards the vocabulary; Γ\_work aggregates resource deltas.)

**CC‑A3‑5 - Episteme as object‑under‑change.**
When the changed holon is an **episteme** (document, dataset, theory), the transformer is still a **system**; the episteme’s history MUST be recorded via **PhaseOf** (versioning) and **ConstituentOf/PortionOf** as appropriate (not via component trees). See A.14’s mereology firewalls and Γ\_epist hooks.

**CC‑A3‑6 - Units and measures for resource effects.**
Any resource consumption/production in `U.Work` MUST specify the **measure μ** and **units** (e.g., kg, J, bytes); “percentage” effects MUST be grounded in a PortionOf μ to be Γ‑aggregatable. (A.14 POR‑axioms; Γ\_work usage.)

**CC‑A3‑7 - Provenance minimum.**
For each `U.RoleAssignment` and `U.Work`, the following fields are REQUIRED: `{authority?, justification?, provenance?}` where `justification: U.Episteme` and `provenance: U.Method`/process evidence. This aligns with the kernel’s governance and B‑cluster lineage practices.

**CC‑A3‑8 - Policy–Plan–Action separation for agentic cases.**
If the transformer bearer is agentic, the log MUST separate `D.Policy → U.PlannedAction → U.Action` (A.15/A.13), preserving where failure occurred (strategy, plan, or execution).

**CC‑A3‑9 - Context‑local conflicts.**
Conflicts among roles (including `TransformerRole`) are only **within the same bounded context**; cross‑context differences are admissible if bridges are declared. Non‑conformance arises only when a context’s own incompatibility rules are violated. (A.2.1 `U.RoleAssignment` invariants.)

**CC‑A3‑10 - Γ‑compatibility.**
Descriptions MUST be sufficient for the relevant Γ‑aggregations to run: Γ\_method for recipe composition, Γ\_work for resource deltas, Γ\_sys for boundary integration, Γ\_time for ordering. Each Γ flavour declares its A.14 hooks (Portion/Phase) and inherits B‑invariants.


### A.3:8 - Consequences

**Benefits**

* **Explainability by construction.** Every transformative claim carries *who/what/when/why/how* via **`U.RoleAssignment`** + provenance fields; audits become mechanical rather than heroic. (B‑invariants and Γ tables do the heavy lifting.)
* **No category errors.** Keeping methods/roles out of mereology and enforcing design/run separation prevents the usual “process‑as‑part” and “version‑as‑component” mistakes. (A.14 + A.15.)
* **Composable analytics.** With measures and boundary folds explicit, cross‑scale proofs (Σ/Π/min/∧/∨) are predictable.
* **Contextual pluralism without chaos.** Divergent domain practices coexist as distinct bounded contexts with bridges; disagreements are localised and tractable.

**Trade‑offs**

* **More declarations up‑front.**  `U.RoleAssignment` + units + policy/plan/action feels verbose, but yields deterministic Γ‑runs and reproducible audits.
* **Discipline for “self‑modifiers.”** Modellers must split controller vs plant or dual‑role the same carrier; this adds one line but avoids hidden identity conflations.


### A.3:9 - Rationale (post‑2015 cross‑domain support)

**Constructor theory (post‑2015).**
Our **Transformer Principle** mirrors constructor theory’s shift from *dynamics* to *tasks*: what transformations are **possible** vs **impossible**, and why. By making the **transformer** (constructor) an explicit bearer of a role and keeping recipes as `MethodDescription`, A.3 captures the core “tasks & constructors” distinction and aligns with constructor‑theoretic thermodynamics linking work, heat, and informational constraints. ([Royal Society Publishing][1], [arXiv][2], [Constructor Theory][3])

**Active inference & free‑energy mechanics (2017→).**
Where transformers are *agentic*, A.3’s policy–plan–action split and boundary‑centred accounting dovetail with **active inference** and **free‑energy** formulations of self‑organising systems (Markov blankets; Bayesian mechanics). This legitimises `U.Objective`/cost function links and makes design–run duality natural (prior vs posterior policies). ([MIT Press Direct][4], [PubMed][5], [arXiv][6])

**Provenance and FAIR packaging (2016→).**
Provenance minima in CC‑A3‑7 reflect **FAIR** principles (machine‑actionable reuse), **RO‑Crate** (methods+data+context packaged together), and operational lineage standards such as **OpenLineage** and **ML Metadata (TFX)** that treat *artefacts, runs, and jobs* as first‑class, with typed facets and versioning — exactly what enactment + Γ\_work need. ([Nature][7], [researchobject.org][8], [SAGE Journals][9], [openlineage.io][10], [GitHub][11], [arXiv][12])

Together, these lines of work argue for **explicit role‑bearing transformers**, **recipe/run separation**, **boundary‑grounded deltas**, and **traceable contexts** — the four pillars that CC‑A3 enforces.


### A.3:10 - Relations

**A.7 Strict Distinction.**
A.3 operationalises A.7 by keeping **object ≠ description ≠ observation**:
*object* = target holon; *description* = `MethodDescription`; *observation/log* = `Work`. Violations (e.g., treating a recipe as a part) are non‑conformant and usually surface as Γ failures.

**A.12 Agent Externalization & External Transformer.**
A.3’s CC‑A3‑1 is the mechanical guard‑rail for A.12: even in self‑modification, the *modelling split* keeps the agent (transformer bearer) distinct from the object‑under‑change.

**A.13 Agential Role.**
When the bearer is an **Agent**, A.3 defers identity and states management to Agent‑CAL (`U.Agent`, `U.Intent`, `U.Action`), while still requiring `RoleAssigning` + Γ compatibility. This is where policy/plan/action pipelines live.

**A.15 Role–Method–Work Alignment.**
A.3 relies on A.15’s vocabulary guard‑rails (roles are not parts; methods are masks of work; specs are recipes). CC‑A3‑2/‑4 are enforceable precisely because A.15 fixes the naming discipline.

**A.14 Advanced Mereology.**
A.3 consumes A.14’s **PortionOf** (for quantitative deltas) and **PhaseOf** (for versioning) and forbids role/recipe leakage into part–whole trees. Γ‑flavours declare which A.14 hooks they use.

**B‑cluster (Γ‑sections).**
A.3 is executable only because Γ‑operators provide aggregation and invariants:

* **Γ\_sys** enforces boundary folds and conservation;
* **Γ\_epist** preserves document/data provenance and versioning;
* **Γ\_time** orders work;
* **Γ\_method** composes recipes;
* **Γ\_work** accounts resource deltas; each inherits B‑invariants (e.g., B‑1 Conservation, B‑2 No‑Duplication).

**Indexing to the glossary.**
Terms used here (TransformerRole, Work, Method, MethodDescription, PortionOf, PhaseOf, BoundedContext) remain exactly as defined in Annex A; see A.1/A.2/A.14/A.15 entries for lexical registers.

### A.3:End

## A.3.1 - U.Method

### A.3.1:1 - Context (plain‑language motivation)

Teams must talk about **how** something is done without entangling:

* **Who** is assigned (that is **Role**/**RoleAssigning**),
* **Whether** the holder can do it (that is **Capability**), and
* **What actually happened** (that is **Work**).

`U.Method` supplies the *how*—the **abstract way of performing a transformation**, independent of a specific run, a specific assignee, or a specific notation. It works across paradigms:

* **Imperative** (step‑graphs, SOPs, BPMN),
* **Functional** (pure mappings and compositions, no “steps”),
* **Logical/constraint/optimization** (goals, rules, admissible solutions).

In FPF, a **system** bearing a **TransformerRole** *enacts* a `U.Method` (producing **Work**) by following a **MethodDescription**—an episteme that describes the method in some representation.

### A.3.1:2 - Problem (what goes wrong without a clean notion of “method”)

1. **Process soup.** “Process” gets used for recipe, execution, schedule, or org area. Planning, staffing, and audit blur together.
2. **Spec = run fallacy.** A flowchart (or code) is taken as if execution already happened; conversely, logs get mistaken for the recipe.
3. **Role leakage.** People encode assignments inside the recipe (“this step is the surgeon”), tying **who** to **how** and making reuse impossible.
4. **Notation lock‑in.** When “method” is defined as “a set of steps,” functional or logical styles become second‑class citizens and cannot be modeled cleanly.

### A.3.1:4 - Solution — the method as an abstract, paradigm‑agnostic “way of doing”

#### A.3.1:4.1 - Definition

**`U.Method`** is a **context‑defined abstract transformation type**—the **semantic “way of doing”** a kind of work.  
It is:
**Described** (never *identical*) by one or more **`U.MethodDescription`** epistemes (code/SOP/diagram/rules),  
**Enacted** by a `U.System` bearing an appropriate **Role** (usually a **TransformerRole**) to produce **`U.Work`**, and  
**Independent** of who is assigned, what instance ran, or which notation was used.

**Strict Distinction (didactic):**  
* **Method** = *how in principle* (semantic Standard).  
* **MethodDescription** = *how it is written* (artifact on a carrier).  
* **Work** = *how it actually went this time* (dated execution).

#### A.3.1:4.2 - Representation‑agnostic stance (specs may be imperative/functional/logical)

A `U.Method` does **not** require an imperative step structure. **Representations live in `U.MethodDescription`, not in the Method itself.**  
Typical **MethodDescription forms** include:

* **Imperative MethodDescription:** step‑graph/flow (serial/parallel/branch).  
* **Functional MethodDescription:** a composition `f ∘ g ∘ h` with typed interfaces/constraints, no “steps”.  
* **Logical/constraint MethodDescription:** a goal/constraint set with admissible solutions and search/optimization semantics.  
* **Hybrid MethodDescription:** imperative scaffolding with functional kernels and/or solver calls.

**Semantic identity criterion (context‑local).** Two MethodDescriptions **describe the same `U.Method`** in a given `U.BoundedContext` iff, for all admissible inputs and conditions recognized by that context, they entail the **same preconditions**, **guarantee the same postconditions/effects**, and satisfy the **same non‑functional bounds** (allowing permitted non‑determinism). Internal control‑flow/search details may differ.


#### A.3.1:4.3 - Method vs MethodDescription vs Work (quick litmus)

| You have in your hand…           | In FPF it is…                 | Why                                                                             |
| -------------------------------- | ----------------------------- | ------------------------------------------------------------------------------- |
| A flowchart/BPMN/SOP text        | **`U.MethodDescription`** (Episteme) | A description on a carrier.                                                     |
| A git repo with code | **`U.MethodDescription`** (Episteme) | Still a description (even if executable). The Method is the semantic “way” it denotes. |
| A log/run report with timestamps | **`U.Work`**                  | A concrete event that happened.                                                 |
| “The way we weld seams type W”   | **`U.Method`**                | The abstract *how*, represented by one or more specs and realized by many runs. |

**Didactic rule:** when referencing *the idea* of “how”, say **Method**; when referencing *the document or code*, say **MethodDescription**; when referencing *the run*, say **Work**.

#### A.3.1:4.4 - Interface and effect (conceptual descriptors)

When presenting a `U.Method` in a review, anchor it with these paradigm‑neutral elements (not a data schema):

1. **Interface** — what is required/provided in general (inputs/outputs/types or resources/roles/ports).
2. **Preconditions** — what must already hold (guards, invariants, Standard “requires”).
3. **Postconditions / Effects** — what is guaranteed after successful enactment (Standard “ensures”).
4. **Non‑functional constraints** — latency, accuracy, cost, safety envelope (ties to **Capability** thresholds).
5. **Failure modes** — known failure classes and recoverability hints.
6. **Compositional hooks** — whether this method composes serially/parallel/choice/iteration (see §4.5).

#### A.3.1:4.5 - Method mereology (composition without confusing it with runtime)

Methods compose into bigger methods; executions compose into bigger executions—**do not conflate** the two.

**Method composition (design‑time):** serial (`-`), parallel (`‖`), choice (`|`), iteration (`*`), refinement/substitution—yield **new `U.Method`s**.
**Work composition (run‑time):** the corresponding **Work** may split/merge/overlap differently due to scheduling, failures, or environment, yet it is still **execution of the same Method**.
**Mapping advice:** avoid naming run‑time artifacts inside the method definition (no “this thread”, “this person”); keep those in **Role**/**Work**.

#### A.3.1:4.6 - Constructor‑theoretic reading (why Method ≠ algorithm ≠ spec)

Constructor Theory views a **constructor** as a physical entity that **effects transformations**. In FPF:

* A `U.System` with **TransformerRole** is the constructor (the performer).  
* A **`U.Method`** is the abstract **transformation type** it enacts (semantic Standard).  
* An **algorithm artifact** is a **`U.MethodDescription`** for an **information‑transformation Method**.  
* A **universal transformer** generalizes the **Turing machine** by **executing any `U.Method` described by a physically admissible `U.MethodDescription`** (not only informational ones).

Thus, welding, milling, reagent mixing, and proof construction are all **Methods**; textbooks/code/derivations are their **MethodDescriptions**; **Work** are the concrete runs.

#### A.3.1:4.7 - Context anchoring

`U.Method` is **local to a `U.BoundedContext`**: terminology, admissible pre/postconditions, and non‑functional constraints are interpreted **inside that context**. If two teams or theories use the same name for different “ways of doing,” they are different Methods in different contexts unless bridged explicitly.


### A.3.1:5 - Archetypal grounding (cross-paradigm examples: imperative / functional / logical)

#### A.3.1:5.1 - Industrial transformation (imperative flavor)

* **Method:** `Etch_Al2O3`.
* **MethodDescription:** SOP document; a PLC program that controls gas mix and timing.
* **Enactment:** `Tool_42#TransformerRole:FabLine_A` produces **Work** runs W‑101, W‑102….
* **Notes:** Step diagram exists, but a later **functional** spec may also exist (composition of gas‑flow functions). Both **specs** describe the **same Method**.

#### A.3.1:5.2 - Operational planning (functional/optimization flavor)

* **Method:** `JS_Schedule_v4` (job‑shop scheduling).
* **MethodDescription:** a MILP model + solver configuration; documentation of constraints/objective.
* **Enactment:** `PlannerService_v4#TransformerRole:PlantScheduling_2025` produces **Work** `Run_2025‑W32‑P1`.
* **Notes:** No “steps” are visible at the method level; the solver’s search is internal. Still a `U.Method`.

#### A.3.1:5.3 - Scientific proof (logical flavor)

* **Method:** `Gauss_Elimination`.
* **MethodDescription:** formal rules in a proof assistant; textbook chapter as a second spec.
* **Enactment:** `CAS_Alpha#TransformerRole:MathLab_2025` generates a **Work** proof instance for a concrete matrix.
* **Notes:** The **Episteme** (spec) is not the **ability** (that belongs to the CAS system) and not the **execution** (the proof run).


### A.3.1:6 - Didactic quick grammar (for managers)

* **Who?** `Holder#Role:Context` (**Role assignment**)
* **Can?** `Capability(holder)` within envelope/measures
* **How (in principle)?** **`Method`**, described by **`MethodDescription`**
* **Did?** **`Work`** (execution), linked by `performedBy → RoleAssigning` and `isExecutionOf → MethodDescription`

> *Keep the four words apart and plans become dependable.*


### A.3.1:7 - Bias‑Annotation (as in cluster‑E patterns)

* **Lenses tested:** `Arch`, `Prag`, `Did`, `Epist`.
* **Scope declaration:** Universal; semantics are context‑local via `U.BoundedContext`.
* **Rationale:** Gives FPF a **paradigm‑neutral** “how” that bridges MethodDescription (knowledge on a carrier) and Work (execution), while staying independent of Role (assignment) and Capability (ability).

### A.3.1:8 - Conformance Checklist (normative)

**CC‑A3.1‑1 (Strict Distinction).**
`U.Method` is the **semantic “way of doing”**. It is **not** a `U.MethodDescription` (artifact on a carrier), **not** a `U.Work` (dated execution), **not** a `U.Role`/assignment, and **not** a `U.ServiceClause`/promise.

**CC‑A3.1‑2 (Context anchoring).**
Every `U.Method` **MUST** be defined **within** a `U.BoundedContext`. Identity, admissible pre/postconditions, and non‑functional bounds are interpreted **in that context**.

**CC‑A3.1‑3 (Specification linkage).**
A `U.Method` **SHOULD** be **described by** ≥1 `U.MethodDescription`. For operational gating, at least one `MethodDescription` **MUST** be present and named. Multiple specs may coexist (imperative/functional/logic), see CC‑A3.1‑7.

**CC‑A3.1‑4 (assignment‑free).**
A `U.Method` **SHALL NOT** hard‑code holders or assignments. If a step “needs a surgeon”, express that as a **role requirement** (to be satisfied via `U.RoleAssignment` at run time), not as a named person/unit inside the method.

**CC‑A3.1‑5 (Runtime‑free).**
A `U.Method` **SHALL NOT** contain schedule, calendar slots, or run IDs; those belong to `U.WorkPlan` (plans) and `U.Work` (executions). Methods are timeless.

**CC‑A3.1‑6 (Interface & effects).**
A `U.Method` **MUST** admit a context‑local statement of interface (inputs/outputs or ports/resources), **preconditions**, **postconditions/effects**, and (when relevant) **non‑functional bounds**. These anchor semantic identity beyond a particular notation.

**CC‑A3.1‑7 (Multi‑spec semantic identity).**
Two or more `U.MethodDescription` **describe the same `U.Method`** in a given context **iff** they entail the **same admissible preconditions**, **guarantee the same effects**, and satisfy the **same non‑functional bounds** for all inputs/conditions recognized by that context (allowing permitted non‑determinism). Internal control‑flow/search differences are irrelevant.

**CC‑A3.1‑8 (Composition vs execution).**
Composition of Methods (design‑time) and composition of Work (run‑time) **MUST** be kept distinct. Method composition yields **new Methods**; Work composition yields **composed executions**. They may correspond but are not identical.

**CC‑A3.1‑9 (Parameterization).**
If a Method is parameterized, parameters are **declared** at the Method/MethodDescription level; **concrete values** are bound **at `U.Work` creation**. Avoid freezing parameter values inside the Method definition.

**CC‑A3.1‑10 (Dynamics ≠ Method).**
Laws/trajectories (`U.Dynamics`) are models of state evolution and **SHALL NOT** be labeled as Methods. A Method **may** rely on a Dynamics model (e.g., for control), but they remain distinct artifacts/concepts.

**CC‑A3.1‑11 (Capability checks are orthogonal).**
A step may impose capability thresholds; those thresholds are checked **against the holder’s `U.Capability`** independently of assignment and independently of the Method’s description.

**CC‑A3.1‑12 (Constructor‑theoretic alignment).**
Algorithm artifacts are `U.MethodDescription` for information‑transforming Methods. Physical Methods are equally valid (matter/energy transformations). A “universal transformer” is a system that can enact **any physically admissible MethodDescription**; this does **not** collapse Method into “algorithm.”


### A.3.1:9 - Method mereology (composition) — design‑time only

**Operators (conceptual, context‑scoped):**

* **Serial composition (`-`)** — do A then B → `A - B` is a new Method.
* **Parallel composition (`‖`)** — do A and B concurrently (with declared independence/joins).
* **Choice (`|`)** — do **one** of {A, B} under guard/selector.
* **Iteration (`*`)** — repeat A under a loop invariant/termination condition.
* **Refinement (`≤ₘ`)** — Method M' preserves M’s interface/effects and **strengthens** preconditions or **tightens** non‑functional bounds (context‑defined lattice).
* **Substitution** — replace a Method factor with a semantically equivalent one (`M ≡ N` in context) without changing the whole’s Standard.

**Design‑time laws (intuitive, not mechanized here):**

* Associativity for `-` and, where admissible, for `‖`.
* Distributivity over guarded choice under context rules.
* Identity elements (e.g., `Skip` that preserves state and satisfies neutral bounds).
* Monotonicity: refinement of a factor **should not** break the whole’s postconditions.

**Run‑time mapping (do not conflate):**
`U.Work` instances of `A - B` **may** interleave differently due to scheduling or failure‑handling and still be executions of `A - B`. The mapping is “execution semantics,” not part of Method mereology.

### A.3.1:10 - How Methods interact with Roles, Capability, Work, Dynamics (manager’s view)

* **Roles (assignment).** Steps stipulate **role kinds** (e.g., `IncisionOperatorRole`), not people. At run time, `U.Work` references a **`U.RoleAssignment`** that satisfies the role kind.
* **Capability (ability).** Steps may require **thresholds** (e.g., “precision ≤ 0.2 mm”). They are checked against the **holder’s `U.Capability`** in the context/envelope.
* **Work (execution).** Each run records `isExecutionOf → MethodDescription` (the spec used) and `performedBy → RoleAssigning`. Logs, resources, and timestamps live here.
* **Dynamics (laws/models).** Methods may cite or assume a Dynamics model; runs may attach traces that are explained by that model. Do not label the model itself as the Method.


### A.3.1:11 - Anti‑patterns (and the right move)

* **Spec = Method.** “The BPMN is the Method.” → The BPMN is a **MethodDescription**; the **Method** is the semantic way it denotes.
* **Run = Method.** “Yesterday’s process is our Method.” → Yesterday’s run is **Work**.
* **Role leakage.** “Step 3 is done by Alice.” → Step 3 **requires** `SurgeonRole`; Alice may be assigned via **RoleAssigning**.
* **Schedule leakage.** “Run at 02:00 daily” inside the Method. → This belongs to **WorkPlan**; Methods are timeless.
* **BoM entanglement.** Putting parts/assemblies inside Method definition. → Structure stays in PBS/SBS; Method references **interfaces/resources**, not a BoM.
* **Algorithm‑only bias.** Declaring that only code counts as a Method. → Physical transformations (welding, mixing) are Methods too; their SOPs/parameters are MethodDescriptions.
* **Hard‑coding capability.** Baking “≤ 0.2 mm” into a role name or Method name. → Keep thresholds on **steps**; **capability** lives on the **holder**.


### A.3.1:12 - Migration notes (quick wins)

1. **Rename wisely.** Where texts say “process/method” but mean a diagram or code repo, label it **MethodDescription**; where they mean the abstract “how,” label it **Method**.
2. **Extract assignments.** Replace named people/units in specs with **role kinds**; enforce assignments via **RoleAssigning** at run time.
3. **Pull time out.** Move calendars/schedules from specs into **WorkPlan**.
4. **Parameter hygiene.** Declare parameters at Method/MethodDescription; bind values in **Work**.
5. **Equivalence notes.** When two specs are intended as the same Method, write an **equivalence note** in the context (pre/post/bounds parity).


### A.3.1:13 - Consequences

| Benefits                                                                                                                    | Trade‑offs / mitigations                                                                           |
| --------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------- |
| **Clarity across paradigms.** Methods are first‑class regardless of notation; teams stop arguing step‑vs‑functional.        | **One more name to learn.** Use the quick grammar card; it pays off fast.                          |
| **Reuse without personnel lock‑in.** assignment moves to RoleAssigning; Methods remain portable.                             | **Extra role tables.** Keep role‑kind lists short and context‑local.                               |
| **Robust audits.** Logs are Work, specs are MethodDescription, Standards are Method; no more “we thought the diagram was the run.” | **Discipline needed.** Enforce the three‑way split in reviews.                                     |
| **Constructor‑theoretic coherence.** Physical and informational transformations are peers.                                  | **Cultural shift.** Not every team is used to seeing SOPs and code as the same class (MethodDescription). |


### A.3.1:14 - Relations

* **Builds on:** A.1 Holonic Foundation; A.1.1 `U.BoundedContext`; A.2 `U.Role`; A.2.1 `U.RoleAssignment`; A.2.2 `U.Capability`.
* **Coordinates with:** A.3 (role masks for transformers/constructors/observers); A.15 (Role–Method–Work Alignment); B.1 Γ (aggregation) for method families vs assembly of systems.
* **Informs:** `U.WorkPlan` definitional pattern (plans reference Methods they schedule); `U.ServiceClause` definitional pattern (promises cite Methods as delivery means); `U.Dynamics` definitional pattern (models that Methods may assume).


### A.3.1:15 - Didactic quick cards (reuse in specs and onboarding)

* **Method / MethodDescription / Work** = *how in principle* / *how it is written* / *how it went this time*.
* **Four‑slot grammar:** Who? → **RoleAssigning**. Can? → **Capability**. How? → **Method** (via **MethodDescription**). Did? → **Work**.
* **Design‑time vs run‑time:** Composition of Methods ≠ composition of Work.
* **No steps required:** Functional, logical, and hybrid MethodDescriptions are first‑class.
* **Keep time and people out:** Schedules → **WorkPlan**; assignees → **RoleAssigning**.
  
### A.3.1:End

## A.3.2 - U.MethodDescription

### A.3.2:1 - Context (plain‑language motivation)

Projects need a **stable way to express “how it is written”**—the recipe, code, SOP, rule set, or formal proof—**without confusing it** with:

* the **semantic “way of doing”** (that is `U.Method`),
* the **assignment** (that is `U.RoleAssignment`),
* the **ability** (that is `U.Capability`),
* the **execution** (that is `U.Work`), or
* the **calendar plan** (that is `U.WorkPlan`).

`U.MethodDescription` gives this anchor. It treats **algorithms, programs, proofs, SOPs, BPMN diagrams, solver models, playbooks** as **one class of epistemes**: *knowledge on a carrier that describes a Method*. This unifies software and “paper” procedures and lets teams switch notations without breaking the model.


### A.3.2:2 - Problem (what breaks without a clear `MethodDescription`)

1. **Spec/run conflation.** A flowchart or code is mistaken for the run; audits and SLOs become unreliable.
2. **Who/time leakage.** People and calendars creep into the recipe; reuse and staffing agility die.
3. **Step‑only bias.** Functional or logical styles are treated as “not real methods”; designs get contorted into faux steps.
4. **Algorithm‑centrism.** Only code is considered “the method”, leaving SOPs and scientific procedures second‑class.
5. **Structure entanglement.** BoM/PBS elements end up inside the recipe; method and product structure tangle.
6. **Unstated equivalence.** Two specs intended to mean “the same method” are not declared equivalent; teams fork semantics by accident.


### A.3.2:3 - Forces (what we must balance)

| Force                              | Tension we resolve                                                                                  |
| ---------------------------------- | --------------------------------------------------------------------------------------------------- |
| **Representation vs. semantics**   | Many notations, one meaning: specs may differ, method stays one.                                    |
| **Universality vs. domain idioms** | SOPs, code, solver models, proofs—all first‑class, yet domain terms remain local.                   |
| **Timelessness vs. operability**   | Specs are timeless, but must be precise enough to drive execution and audit.                        |
| **Reusability vs. constraints**    | Specs should declare role kinds, capabilities, safety bounds—without baking in people or calendars. |
| **Evolvability vs. identity**      | Specs change; we need a way to evolve them without losing the method’s identity or history.         |


### A.3.2:4 - Solution — the specification as an episteme describing a Method

#### A.3.2:4.1 - Definition

**`U.MethodDescription`** is an **`U.Episteme`** that **describes a `U.Method`** in a concrete representation (text, code, diagram, model). It is **knowledge on a carrier** that can be reviewed and validated; at run-time a **`U.System`** **uses it to execute the `U.Method` as `U.Work` under a `U.RoleAssignment`**.

> **Strict Distinction (memory aid):**
> **Method** = *how in principle* (semantic Standard).
> **MethodDescription** = *how it is written* (artifact/description).
> **Work** = *how it went this time* (dated execution).

#### A.3.2:4.2 - Representation‑agnostic stance (independent of “algorithmic paradigm”)

`U.MethodDescription` **does not privilege any single notation**. Typical forms include (non‑exhaustive):

* **Imperative Spec** — SOP, BPMN/flowchart, PLC ladder, shell/pipeline scripts.
* **Functional Spec** — compositions of pure functions, typed pipelines, category‑style combinators.
* **Logical/Constraint Spec** — rules/goal sets, SAT/SMT/MILP models, theorem‑prover scripts.
* **Statistical/ML Spec** — model definitions, training/evaluation procedures, inference pipelines.
* **Reactive/Event‑driven Spec** — statecharts, observers/triggers, stream/CEP rules.
* **Hybrid Spec** — mixtures (e.g., imperative orchestration calling solver kernels).

**Same Method, different MethodDescriptions.** In a single `U.BoundedContext`, several MethodDescriptions **may describe the same `U.Method`** if they entail the **same preconditions**, **guarantee the same effects**, and meet the **same non‑functional bounds** (cf. A.3.1).

#### A.3.2:4.3 - What a good MethodDescription states (paradigm‑neutral content)

Not a schema—these are **content prompts** for reviewers:

1. **Purpose & Name of the Method** it describes (link to `U.Method`).
2. **Interface/ports** (inputs/outputs/resources/Standards) in the context’s vocabulary.
3. **Preconditions** (guards, invariants, required states).
4. **Postconditions / Effects** (what is guaranteed upon success).
5. **Non‑functional constraints** (latency, precision, cost, safety envelope).
6. **Role requirements** for enactment (**kinds**, not people)—to be satisfied at run time via **`U.RoleAssignment`**.
7. **Capability thresholds** the performer must meet (checked against **`U.Capability`** of the holder).
8. **Failure semantics** (detectable failures, compensations, rollback/forward strategies).
9. **Compositional hooks** (how this spec composes: serial/parallel/choice/iteration), without embedding calendars.
10. **Parameter declarations** (what may vary per run; values bound at `U.Work` creation).

> **Didactic guardrail:** A MethodDescription **does not** embed a schedule, assignees, or BoM. Calendars → `U.WorkPlan`; people/units → `U.RoleAssignment`; product structure → PBS/SBS.

#### A.3.2:4.4 - Epistemic roles for MethodDescriptions (via `U.RoleAssignment`)

Being an Episteme, a MethodDescription may itself play epistemic roles via `U.RoleAssignment` in a context (classification, not action), e.g.:

* `ApprovedProcedureRole`, `RegulatedProcedureRole`, `SafetyCriticalProcedureRole`, `De‑factoStandardRole`.
* These **do not** make the spec an actor; they classify its **status** within the context (who may use it, in which settings).

#### A.3.2:4.5 - Constructor‑theoretic note (unifying “algorithms” and “physical recipes”)

In the constructor‑theoretic reading used by FPF:

* **Algorithms, programs, solver models, proofs** are all **`U.MethodDescription`**—descriptions of Methods that transform **information**.
* **SOPs, control recipes, lab protocols** are **`U.MethodDescription`**—descriptions of Methods that transform **matter/energy**.
* A **universal transformer** (a system with sufficient capability) enacts **any physically admissible MethodDescription**—not only informational ones.

This keeps software and “wet lab” on equal footing.


### A.3.2:5 - Clear distinctions (quick litmus for managers)

### A.3.2:6 - Archetypal grounding (parallel cases)

#### A.3.2:6.1 - Industrial SOP (imperative)

* **Method:** `Etch_Al2O3`.
* **MethodDescription:** `SOP_Etch_v7.pdf` + PLC ladder file.
* **Role requirements:** `EtchOperatorRole`; **Capability:** gas‑control precision ≤ threshold.
* **Execution:** `Tool_42#TransformerRole:Fab_A` enacts the spec → **Work** runs W‑143…W‑155.

#### A.3.2:6.2 - Optimization model (logical/constraint)

* **Method:** `JS_Schedule_v4`.
* **MethodDescription:** MILP model + solver config; admissible solution definition.
* **Execution:** `PlannerService_v4#TransformerRole:Plant_2025` produces **Work** `Run_2025‑W32‑P1`.

#### A.3.2:6.3 - Clinical guideline (epistemic, status via RoleStateGraph + State Assertion)

* **Method:** `AcuteAppendicitis_Triage`.
* **MethodDescription:** clinical decision rule set; **Epistemic Role**: `RegulatedProcedureRole:Hospital_Context`.
* **Execution:** `ER_Team#TransformerRole:ER_Shift` enacts the spec on a case → **Work** visit V‑8842.


### A.3.2:7 - Bias‑Annotation (as in E‑cluster)

* **Lenses tested:** `Did`, `Prag`, `Arch`, `Epist`.
* **Scope declaration:** Universal; semantics are **context‑local** via `U.BoundedContext`.
* **Rationale:** Elevates **all** procedural artifacts—code, SOPs, proofs, models—to a single class, avoiding algorithm‑centrism and step‑only bias. Keeps the strict split among **Method / MethodDescription / Work / Role / Capability**.

### A.3.2:8 - Conformance Checklist (normative)

**CC‑A3.2‑1 (Episteme status).**
`U.MethodDescription` **IS** an `U.Episteme` (knowledge on a carrier). It is **not** a `U.Method` (semantic way), **not** a `U.Work` (execution), **not** a `U.Role/RoleAssigning` (assignment), **not** a `U.WorkPlan` (schedule), and **not** PBS/SBS content.

**CC‑A3.2‑2 (Context anchoring).**
Every `U.MethodDescription` **MUST** be interpreted **within** a `U.BoundedContext`. Names, Standards, and admissible non‑functional bounds are **local** to that context.

**CC‑A3.2‑3 (Method linkage).**
A `U.MethodDescription` **MUST** declare the `U.Method` it describes. Multiple MethodDescriptions **MAY** describe the same Method (see CC‑A3.2‑8).

**CC‑A3.2‑4 (assignment/time‑free).**
A MethodDescription **SHALL NOT** embed assignees, org units, or calendars. People/units are bound via **`U.RoleAssignment`** at run time; calendars belong to **`U.WorkPlan`**.

**CC‑A3.2‑5 (Structure‑free).**
BoM/PBS/SBS artifacts **SHALL NOT** be embedded in MethodDescriptions. Reference **interfaces/resources** and constraints instead of listing parts/assemblies.

**CC‑A3.2‑6 (Role and capability requirements).**
A MethodDescription **MAY** state **role kinds** and **capability thresholds** required for enactment. These are **requirements**, not bindings. They are checked at run time against `U.RoleAssignment` and `U.Capability`.

**CC‑A3.2‑7 (Parameterization).**
Parameters **MUST** be **declared** in the Method/MethodDescription; concrete values are **bound** when creating `U.Work`. Default values in a spec are allowed but **SHALL NOT** force a schedule or assignee.

**CC‑A3.2‑8 (Semantic equivalence).**
Two MethodDescriptions **describe the same `U.Method`** in a given context **iff** they entail the **same preconditions**, **guarantee the same postconditions/effects**, and satisfy the **same non‑functional bounds** for all admissible inputs/conditions of that context (per A.3.1 CC‑A3.1‑7). Differences in control flow, search, or notation do **not** break equivalence.

**CC‑A3.2‑9 (Refinement).**
`Spec₂` **refines** `Spec₁` for the same Method iff it **preserves interface**, **does not weaken** postconditions/effects, and **tightens** (or equal) non‑functional bounds under **equal or stronger** preconditions. Declare refinement explicitly in the context.

**CC‑A3.2‑10 (Compatibility claims).**
Claims such as “sound but incomplete” or “complete but potentially unsound” relative to another MethodDescription **MUST** be stated explicitly and scoped to the context (e.g., solver approximations).

**CC‑A3.2‑11 (Executable specs).**
Executability does **not** change status: an executable artifact (program, script) is still a **MethodDescription**. Its runs are **Work**; its semantics are the **Method** it denotes.

**CC‑A3.2‑12 (Epistemic roles via `U.RoleAssignment`).**
A MethodDescription **MAY** play **epistemic roles** via `U.RoleAssignment` (e.g., `ApprovedProcedureRole`, `RegulatedProcedureRole`) that classify its status. Such bindings **do not** make the spec an actor.

**CC‑A3.2‑13 (Non‑determinism declaration).**
If a MethodDescription permits non‑determinism (e.g., search/optimization), the **space of admissible outcomes** and **acceptance criteria** **MUST** be stated (so that Work can be judged).

**CC‑A3.2‑14 (Bridging across contexts).**
If two contexts use different MethodDescriptions for “the same‑named way,” an explicit **Bridge (`U.Alignment`)** **SHOULD** be provided to map terms/assumptions. Do **not** assume cross‑context identity by name alone.


### A.3.2:9 - MethodDescription mereology (epistemic composition; not method composition)

Keep two worlds separate:

* **Method composition (design‑time semantic):** combines Methods into **new Methods** (A.3.1 §9).
* **MethodDescription mereology (epistemic):** combines **documents/code/models** into larger **spec artifacts**. This is about **parts of the description**, not about the semantic method algebra.

**Epistemic part relations (illustrative):**

* **`ConstituentOf`** — a chapter/module/snippet is a constituent of a larger spec.
* **`Imports/Uses`** — this spec reuses a library/rule set.
* **`VariantOf`** — this spec is a variant (e.g., for different equipment) with declared deltas.
* **`RepresentationOf`** — this visual diagram is a representation of the textual rule set.

**Didactic rule:** Do not infer that a spec with two modules **means** a Method with “two steps.” Modules are **parts of the description**, not necessarily steps of the Method.


### A.3.2:10 - Parameterization & variability (templates, defaults, configs)

**Templates.** A MethodDescription may serve as a **template** with parameters (e.g., temperature set‑points, solver tolerances, objective weights).

**Binding time.**

* **Declare** parameters in the spec;
* **Bind** values when creating `U.Work` (or at an agreed “compile” stage);
* Keep bound values **visible** in the Work record (so runs can be compared).

**Defaults and guards.**

* Defaults are allowed; list **valid ranges** and **guards** (e.g., safety constraints).
* If a default has safety impact, state it explicitly as part of **preconditions**.

**Variants.**

* When variants differ only by **parameter ranges** → keep one Method with one MethodDescription template.
* When variants differ by **Standard** (effects/bounds) → either declare a **refinement** or introduce a **distinct Method** (context decision).


### A.3.2:11 - Equivalence & compatibility (across notations and contexts)

**Within one context.**

* Use **semantic equivalence** (CC‑A3.2‑8) to assert that BPMN vs code vs solver model are the **same Method**.
* Prefer a short **equivalence note** showing parity of pre/post/bounds.

**Across contexts.**

* Treat identity as **not guaranteed**.
* Provide **Bridges (`U.Alignment`)** that map terms, units, roles, and acceptance criteria.
* Be explicit if one spec is only **sound** (never returns forbidden outcomes) vs **complete** (can return all allowed outcomes).

**Observational perspective (pragmatic).**
Two specs are observationally equivalent for stakeholders **if**, under declared conditions, they are indistinguishable by the acceptance tests of that context (even if internal strategies differ).


### A.3.2:12 - Anti‑patterns (and the right move)

* **Spec = run.** “Yesterday’s process log is our spec.” → The log is **Work**; write a **MethodDescription** and link runs to it.
* **Who/time in the spec.** “Step 3 by Alice at 02:00 daily.” → Use **RoleAssigning** at run time; schedule via **WorkPlan**.
* **Stuffing BoM.** Listing parts/assemblies inside the spec. → Reference **interfaces/resources**; keep PBS/SBS separate.
* **Algorithm‑only bias.** Treating code as “real spec” and SOPs as “notes.” → Both are **MethodDescription**; judge by Standards, not by format.
* **Hiding non‑determinism.** Solver model with no acceptance criteria. → Declare admissible outcome set and tests.
* **Silent parameter capture.** Hard‑coding values without declaring parameters. → Declare parameters with ranges; bind at Work creation.
* **Undeclared variant drift.** Copy‑pasting specs and tweaking silently. → Use **VariantOf** with stated deltas or declare a refinement.


### A.3.2:13 - Migration notes (quick wins)

1. **Label the artifacts.** Wherever a repo/diagram/document “is the process,” rename it **MethodDescription** and link it to a named **Method**.
2. **Extract people and calendars.** Move all assignees to **RoleAssigning** and all schedules to **WorkPlan**.
3. **Introduce parameter blocks.** Add a small “Parameters” section with ranges/defaults and safety guards.
4. **Write acceptance criteria.** Especially for search/optimization or ML specs.
5. **Declare equivalence/refinement.** Where two notations intend “the same way,” add an **equivalence note**; where the new one tightens bounds, declare **refinement**.
6. **Bridge domains.** If two departments use different vocabularies, add a **Bridge (`U.Alignment`)** rather than forcing a single spec.


### A.3.2:14 - Consequences

| Benefits                                                                                                          | Trade‑offs / mitigations                                                                           |
| ----------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------- |
| **One class for all recipes.** SOPs, code, models, proofs become peers; teams can choose the best notation.       | **A bit more ceremony.** You name the Method and the MethodDescription separately; the payoff is clarity. |
| **Cleaner audits.** Specs vs runs vs assignments vs abilities never mix.                                         | **Discipline required.** Keep schedules and people out of specs.                                   |
| **Easier reuse and substitution.** Equivalence/refinement rules enable swapping notations without semantic drift. | **Equivalence is a claim.** Back it with short acceptance tests.                                   |
| **Cross‑domain coherence.** Bridges allow controlled translation between contexts.                                | **Bridge maintenance.** Someone owns the mapping; keep it short and focused.                       |


### A.3.2:15 - Relations

* **Builds on:** A.3.1 `U.Method` (the semantic way it describes); A.1.1 `U.BoundedContext`.
* **Coordinates with:** A.2 `U.Role`, A.2.1 `U.RoleAssignment` (who enacts it); A.2.2 `U.Capability` (ability thresholds); A.15 Role–Method–Work (linking `isExecutionOf` to runs).
* **Informs:** `U.WorkPlan` (plans reference MethodDescriptions); `U.Dynamics` (models that specs may assume); Epistemic Role patterns (status of specs RoleStateGraph + State Assertion).
* **Lexical guards:** E.10.y **L‑PROC** (do not call MethodDescription “process” when you mean Work/WorkPlan); E.10.x **L‑FUNC** (avoid “function/functionality” confusion).


### A.3.2:16 - Didactic quick cards

* **Spec ≠ Method ≠ Work.** *Written recipe* ≠ *semantic way* ≠ *dated execution*.
* **Keep people/time out.** Assignees → **RoleAssigning**; schedules → **WorkPlan**.
* **Declare parameters & acceptance.** Bind values at Work; state how success is judged.
* **Same method, different specs.** BPMN/code/solver can be equivalent **if** pre/post/bounds match.
* **Bridge, do not blur.** Cross‑team/domain differences go through **`U.Alignment`**, not wishful thinking.
  
### A.3.2:End

## A.3.3 - `U.Dynamics`

### A.3.3:1 - Context

Teams need one place to say **how a thing changes**. Physicists call this “dynamics” (equations of motion, state‑transition maps). In IT and enterprise change, we often talk about **evolution of characteristics** (latency, cost, reliability, compliance, architectural fitness) across time. In knowledge work, **KD‑CAL** (knowledge dynamics) reasons about how the **status of claims** shifts as evidence arrives. All these are *the same modeling need*: a context‑local description of **state space** and **allowed transitions**.

FPF already separates:

* **what a holon is** (structure, PBS/SBS),
* **how we act** (Method/MethodDescription, Work),
* **what we promise** (Service).

What is missing without `U.Dynamics` is the **law of change**—the model that tells us how states evolve **with or without** our interventions.

> Intuition: **Method** tells an agent what to do; **Dynamics** tells everyone how the world (or a model of it) changes when something happens (or even when nothing happens).

**Lexical note.** Terms like *process* and *thermodynamic process* are mapped by **L‑PROC**:

* the **recipe** is `U.Method/MethodDescription`,
* the **dated run** is `U.Work`,
* the **law/trajectory model** is `U.Dynamics`.

### A.3.3:2 - Problem

Without a first‑class `U.Dynamics`, models suffer predictable failures:

1. **Recipe = Law.** Teams put the *procedure* (Method/MethodDescription) where the *state law* should be, so simulations and predictions become impossible to compare with reality.
2. **Run = Law.** Logs of Work are mistaken for dynamics; past events are treated as if they defined what *must* happen.
3. **No state space.** Discussions jump between metrics (latency! throughput!) without an explicit **characteristic space** or invariants, so “improvements” cannot be reasoned about.
4. **Domain lock‑in.** “Dynamics” is left to domain vocabularies (physics, control, finance), losing a trans‑disciplinary way to speak about change in a single kernel.

### A.3.3:3 - Forces

| Force                                  | Tension                                                                                                                 |
| -------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- |
| **Universality vs. richness**          | One kernel notion must cover ODE/PDE, Markov chains, queues, discrete events, and enterprise “fitness characteristics”. |
| **Model vs. reality**                  | A law must be **design‑time** (an `Episteme`), yet judged by **run‑time** evidence (Work).                              |
| **Continuous vs. discrete vs. hybrid** | Different time bases and update rules must coexist.                                                                     |
| **Open vs. closed systems**            | Exogenous inputs (control/disturbances) may be explicit or implicit.                                                    |
| **Predictive use vs. diagnostic use**  | The same dynamics can guide planning or explain incidents; interfaces must support both.                                |


### A.3.3:4 - Solution — The unified concept `U.Dynamics`

**Definition (normative).**
Within a `U.BoundedContext`, **`U.Dynamics`** is an **`U.Episteme` that specifies a state space and a state‑transition law** (deterministic or stochastic, continuous/discrete/hybrid) for one or more holons, possibly under exogenous inputs and constraints. It **does not** prescribe what an agent should do (that is `U.Method/MethodDescription`) and **is not** the dated evolution itself (that is `U.Work` evidence).

* **Type:** `U.Episteme` (design‑time model/law on a carrier).
* **Orientation:** descriptive/predictive about **how states evolve**; can be used by Methods but remains separate from them.
* **Judged by:** conformance of observed **Work‑derived traces** to the law and invariants.

#### A.3.3:4.1 - Core structure (minimal fields)

```
U.Dynamics {
  context        : U.BoundedContext,     // where the model’s meaning and units are defined
  stateSpace     : CharacteristicSpace,  // explicit characteristics & units; may include topology/geometry
  transitionLaw  : Episteme,             // equations/relations/kernels/transition matrices/rules
  timeBase       : {continuous|discrete|hybrid},
  stochasticity? : {deterministic|stochastic}, // incl. noise/likelihood model if stochastic
  inputs?        : P(Characteristic),    // control/disturbances/environmental drivers
  observation?   : Episteme,             // measurement/observation map from state to observables
  constraints?   : Episteme,             // invariants/safety envelopes/guards
  validity?      : Conditions,           // operating region, approximations, version, timespan
  calibration?   : Episteme              // parameter identification / priors
}
```

* **`stateSpace`** uses FPF **characteristics** (not “characteristics”) so we can talk about **architecture fitness** (e.g., latency, MTBF, cost) just like temperature/pressure/volume in physics.
* **`transitionLaw`** is paradigm‑agnostic: ODE/PDE, finite‑state relation, Petri net firing, queueing kernel, Bayesian update, etc.
* **`observation`** separates what exists from what we *measure* (key for monitoring/assurance).

#### A.3.3:4.2 - What `U.Dynamics` is **not**

* **Not a Method/MethodDescription:** no imperative steps or prescriptions.
* **Not Work:** no timestamps/resources attached; evidence lives on `U.Work`.
* **Not a Service:** no consumer promise; dynamics may underpin service SLOs but does not define the promise.
* **Not PBS/SBS:** do not place dynamics inside structural BoMs.


### A.3.3:5 - Where `U.Dynamics` sits in enactment

* **Design‑time:**
  Methods may *reference* Dynamics for planning/control (e.g., MPC uses a plant model).
  Services may *derive* acceptance targets from Dynamics (e.g., queueing predictions → SLO).

* **Run‑time:**
  Work produces **state samples/telemetry**; applying the **observation** map yields traces.
  Conformance/violation is decided by comparing traces with **constraints** and predictions from the transition law.
  Updates to model parameters flow via **calibration** (design‑time again).

> Memory hook: **Method decides**, **Dynamics predicts**, **Work reveals**.

### A.3.3:6 - Prediction Use In Gating (normative)

When **predicted** coordinates (from a dynamics model) are used for **comparison or gating**, one of the following **MUST** hold:
1) a **fresh observation** is available for the gate’s window; or
2) the applied flow/map `Φ_{Δt}` is proven **non‑expansive** (Lipschitz ≤ 1) under the declared distance overlay (see § 5.1.7), **and** it **commutes** with the invariantization step (§ 5.1.6) — i.e., `Quot/Fix_g ∘ Φ_{Δt} = Φ_{Δt} ∘ Quot/Fix_g` on the domain of use.

If neither condition is satisfied, using prediction for gating is **forbidden**; the system **MUST** fall back to observation. Any use of `Φ_{Δt}` **SHALL** declare its validity window (range, Δt).

### A.3.3:7 - Archetypal grounding (engineer‑manager friendly)

| Domain                        | Holon & State Space                     | Transition Law Example               | Observation                 | Typical Questions                                                 |
| ----------------------------- | --------------------------------------- | ------------------------------------ | --------------------------- | ----------------------------------------------------------------- |
| **Process control**           | Reactor: {Temperature, Concentration}   | Non‑linear ODE with disturbance term | Thermocouples, analyzers    | Will we overshoot? What control horizon keeps safety constraints? |
| **Reliability/ops**           | Service platform: {MTBF, MTTR, Backlog} | Birth–death/queueing model           | Incident logs, uptime pings | Given load, what SLO is feasible?                                 |
| **Evolutionary architecture** | System: {Latency, Cost, Coupling}       | Discrete‑time map per release        | Perf tests, bills           | If we change X, how does latency trend next 3 sprints?            |
| **KD‑CAL (knowledge)**        | Claim: {Belief, Support}                | Bayesian update rule                 | Evidence artifacts          | How does confidence evolve as studies arrive?                     |

**Key takeaway:** one kernel object captures **trajectories in a characteristic space**, from thermodynamics to software quality and knowledge confidence.

### A.3.3:8 - Conformance Checklist (normative)

**CC‑A3.3‑1 (Type).**
`U.Dynamics` **IS** an `U.Episteme` (design‑time model/law on a carrier). It is **not** a `U.Method/MethodDescription`, **not** `U.Work`, and **not** a structural part of any PBS/SBS.

**CC‑A3.3‑2 (Context).**
Every `U.Dynamics` **MUST** be declared **inside** a `U.BoundedContext`. Units, characteristic names, admissible regions, and time base are **local to the context**; cross‑context reuse requires a Bridge (`U.Alignment`).

**CC‑A3.3‑3 (Explicit state space).**
`stateSpace` **MUST** enumerate characteristics with units/scales (continuous/discrete/ordinal) and any topology/geometry needed for trajectories. Do **not** refer to informal “axes”.

**CC‑A3.3‑4 (Transition law).**
`transitionLaw` **MUST** specify a state‑transition relation/map/kernel suitable for the declared time base (`continuous|discrete|hybrid`) and stochasticity (deterministic or with a likelihood/noise model).

**CC‑A3.3‑5 (Observation model).**
If evidence from `U.Work` is to be checked against the law, an `observation` mapping **MUST** be provided (identity is acceptable only if explicitly stated). Sampling rate/granularity **SHOULD** be declared.

**CC‑A3.3‑6 (Constraints & validity).**
If safety/envelope constraints apply, they **MUST** be declared under `constraints`. Operating region, approximations, version, and `timespan` **SHOULD** be stated under `validity`.

**CC‑A3.3‑7 (Separation from Method).**
A `U.Dynamics` **SHALL NOT** prescribe imperative steps or responsibilities. Planning/control algorithms that *use* the dynamics belong to `U.Method/MethodDescription`.

**CC‑A3.3‑8 (No actuals on Dynamics).**
Resource/time **actuals** and telemetry **MUST** attach to `U.Work`. Calibration outcomes produce **new versions** of `U.Dynamics`; the law object itself carries no run‑time logs.

**CC‑A3.3‑9 (Multi‑scale declaration).**
If state is aggregated across parts or time, the aggregation policy (`Γ_time`, `Γ_work`, averaging vs. sum vs. percentile) **MUST** be stated to prevent incoherent comparisons.

**CC‑A3.3‑10 (Lexical hygiene).**
Ambiguous uses of *process/processual* (laws vs. runs vs. recipes) **MUST** be resolved per **L‑PROC**/**L‑ACT**:

* law → `U.Dynamics`,
* recipe → `U.Method/MethodDescription`,
* run → `U.Work`.

**CC‑A3.3‑11 (Link to Services—optional).**
If Service SLOs are derived from a dynamics model, the Service **SHOULD** reference that `U.Dynamics` (A.2.3), but the Service remains the promise, not the law.


### A.3.3:9 - Evidence and operators (traces, prediction, conformance)

Let `D` be a `U.Dynamics` in context `C`. Let `W` be a set of `U.Work` records produced under `C`. Let `obs_D(-)` be the declared observation map for `D`.

#### A.3.3:9.1 - Derived evidence

* **`trace(W, D)` → Sequence\<t, y>:**
  derive an ordered sequence of observed values `y` at times `t` by applying `obs_D` to Work/telemetry associated with `W`. (Not a kernel type; a derived artifact for analysis/assurance.)

* **`inputs(W)` → Series:**
  exogenous inputs/control signals recovered from Work metadata if the model declares `inputs`.

* **`initialState(W, D)` → x₀:**
  the assumed/estimated state at trace start (from Work context or a stated estimation rule).

#### A.3.3:9.2 - Prediction & simulation

* **`predict(D, x₀, inputs?, horizon)` → Trajectory:**
  propagate the law to obtain a predicted trajectory in the declared state space.

* **`admissible(D, x)` → bool:**
  test whether state `x` satisfies `constraints`.

* **`reach(D, S₀, S₁, inputs?, horizon)` → bool:**
  reachability: can states in `S₀` evolve into `S₁` under the law.

#### A.3.3:9.3 - Conformance & drift

* **`residuals(D, trace)` → Series:**
  discrepancies between predicted and observed series under a stated alignment (point‑wise, windowed, distributional).

* **`fits(D, trace, tol)` → {pass|fail|partial}:**
  verdict under tolerance policy `tol` defined by the context (e.g., sup‑norm ≤ ε, percentile bands, likelihood threshold).

* **`drift(D₁, D₂, domain)` → Measure:**
  divergence between two model versions over a declared operating domain (e.g., max deviation of eigenvalues, KL between predictive distributions).

#### A.3.3:9.4 - Invariants

* `fits(D, trace, tol)=pass` ⇒ every sample lies in `admissible(D,-)` unless the context explicitly permits out‑of‑envelope transients.
* If two traces are generated under identical `inputs` and initial conditions, recorded differences must be explainable by the declared stochasticity/noise model or flagged as violations.

> **Didactic hook:** *Dynamics predicts; Work reveals; Conformance compares.*


### A.3.3:10 - Anti‑patterns (and the right move)

* **“Dynamics = procedure.”**
  Control recipes/step graphs belong to `Method/MethodDescription`. Keep the law in `U.Dynamics`.

* **“Telemetry = dynamics.”**
  Logs are `Work` evidence. Build `trace(Work, D)` and compare to the law; do not store logs inside the law.

* **“No state space.”**
  KPI lists without an explicit `stateSpace` turn into dashboard folklore. Name characteristics with units and ranges.

* **“Hard‑coding SLO inside the law.”**
  Service targets are promises (`U.ServiceClause.acceptanceSpec`). Keep predictions and promises separate; link them.

* **“Stuffing Dynamics into BoM.”**
  A model is not a component. Leave PBS/SBS for structure.

* **“One size fits all time base.”**
  If parts of the system evolve on different clocks, declare `hybrid` and separate update rules.


### A.3.3:11 - Migration notes (quick path to value)

1. **Name the changing things.** Pick 3–7 **characteristics** that matter (physical or architectural). Declare `stateSpace` with units and ranges.
2. **Write the law you already use.** Even if it is a queueing approximation or a simple ARIMA—put it under `transitionLaw` and state assumptions under `validity`.
3. **Separate recipe from law.** Move control procedures to `Method/MethodDescription`; keep forecasting/plant equations in `U.Dynamics`.
4. **Wire evidence.** Ensure production `Work` emits the measurements needed by `observation`. Build `trace(Work, D)`.
5. **Start conformance.** Define a simple `tol` and compute `fits(D, trace, tol)` weekly. Raise issues on drift; version the model when calibrating.
6. **Link to promises (optional).** If SLOs depend on the law, reference `U.Dynamics` from `U.ServiceClause` and derive targets transparently.
7. **For KD‑CAL.** Treat belief/support as characteristics; declare a Bayesian/likelihood update in `transitionLaw`; evaluate conformance against evidence arrivals.


### A.3.3:12 - Relations

* **Builds on:**
  `A.1.1 U.BoundedContext` (local meaning/units),
  `A.2 Role` / `A.2.1 RoleAssigning` (agents that *use* the law),
  `A.15.1 U.Work` (run‑time evidence).

* **Coordinates with:**
  `A.3.1 U.Method` / `A.3.2 U.MethodDescription` (planning/control using the law),
  `A.2.3 U.ServiceClause` (promises informed by predictions),
  **KD‑CAL** (knowledge dynamics as a specialisation: belief‑update laws),
  **Resrc‑CAL** (cost/energy models as dynamics over resources).

* **Constrained by lexical rules:**
  **E.10 L‑PROC** (process disambiguation), **L‑ACT** (activity/action), **L‑FUNC** (function).


### A.3.3:13 - Didactic quick cards (engineer‑manager ready)

* **Dynamics = Law of Change.** A design‑time model of how states evolve.
* **State space = Named characteristics with units.** No vague “axes”.
* **Method vs Dynamics.** Method decides *what we do*; Dynamics predicts *what will happen*.
* **Work = Evidence.** Only Work has timestamps and resource actuals.
* **Conformance = Prediction vs Trace.** Fit, residuals, drift.
* **Keep promises separate.** Services are promises; Dynamics informs them but does not replace them.

**Memory hook:** **Method decides - Dynamics predicts - Work reveals.**
