## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | SEMANTICS-NOTES.md remains non-normative; v0.2 draft remains draft; no shipped enforcement claimed |
| Canonical sources/paths verified | yes | Both target files confirmed in diff; TSC cross-refs use `usurobor/tsc spec/` form consistent with external-repo citations |
| Scope/non-goals consistent | yes | v0.1 LANGUAGE-SPEC.md untouched; no ctb-check implementation; no TSC spec changes; no metaphysical overclaims |
| Constraint strata consistent | n/a | No constraint strata in docs-only change |
| Exceptions field-specific/reasoned | n/a | |
| Path resolution base explicit | n/a | No path validation involved |
| Proof shape adequate | n/a | Docs-only; no checker/validator/CI surface |
| Cross-surface projections updated | yes | CTB README describes SEMANTICS-NOTES as non-normative (accurate); VISION doc §64/§471 TSC references consistent with new §15.1 framing; no source map gaps |
| No witness theater / false closure | yes | New §15.6 explicitly states CTB does not implement TSC measurement; ctb-check deferred; structural parallels documented as conceptual grounding only |
| PR body matches branch files | yes | self-coherence.md accurately describes the two changed files and the exact section additions |

## §2.0 Issue Contract

### AC Coverage
| # | AC | In diff? | Status | Notes |
|---|----|----------|--------|-------|
| 1 | TSC formal upstream stated in §15.1 with C≡ §1.2, §2.1–2.2, §3.1–3.4, TSC Core §7.2 | yes | met | §15.1 opens with "TSC (usurobor/tsc) is the formal upstream for CTB's triadic carrier claim"; all four required section cites present |
| 2 | CTB keeps the right level of claim (no metaphysical overclaim; operational carrier distinction) | yes | met | §15.1 "What CTB claims and does not claim" subsection quotes TSC Core §0 non-claim; distinguishes formal backing from agent-execution generalization |
| 3 | Witness model mapped to CTB close-outs | yes | met | §15.6 state machine side-by-side + table mapping TSC-Oper outcomes to `accepted`/`repair-needed`/`structured-failure`/`blocked`/`close-with-debt` |
| 4 | Witness theater mitigation points to TSC-Oper W1–W4 | yes | met | §15.6 names all four witnesses with CTB-specific readings; ctb-check implication stated; LANGUAGE-SPEC-v0.2-draft.md §15 adds cross-reference pointer |
| 5 | Composition bound informs join semantics without overclaiming | yes | met | §15.3 "Composition bound and join semantics" includes exact theorem, CTB implication, and explicit non-overclaim caveat |
| 6 | ctb-check dependency noted | yes | met | §15.6 "ctb-check v0 dependency": field presence is minimum, not sufficient; independent witness signals preferred |

### Named Doc Updates
| Doc / File | In diff? | Status | Notes |
|------------|----------|--------|-------|
| `docs/alpha/ctb/SEMANTICS-NOTES.md` | yes | complete | §15.1 expanded; §15.3 subsection added; §15.6 new section |
| `docs/alpha/ctb/LANGUAGE-SPEC-v0.2-draft.md` | yes | complete | 2-line cross-reference added to §15 witness theater block |

### CDD Artifact Contract
| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| `self-coherence.md` | yes | yes | 168 lines; review-readiness at R1 signaled at `717cdba9`; pre-review gate §2.6 complete |
| Bootstrap (version dir) | no | n/a | Small-change path; docs-only update to non-normative file; no new version snapshot directory required — correctly exempted |
| `beta-review.md` | yes | this file | |

### Active Skill Consistency
| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| `cnos.core/skills/write/SKILL.md` | Tier 2 (docs change) | yes | yes | Prose is functional, precise, non-redundant; write skill governs documentation quality |

## Notes

**CI state:** Confirmed n/a for this branch shape. The CI workflow triggers on `push: main` and `pull_request: main` only; no CI run is available for `origin/cycle/297` without a PR. The diff is purely Markdown — no Go files, no schema-bearing artifacts, no test fixtures. No CI gate applies.

**Pre-merge gate:** Row 1 (identity) — `beta@cdd.cnos` asserted at intake and verified. Row 2 (canonical-skill freshness) — `origin/main` confirmed at `eb7617e7` at both intake and pre-merge sync (up to date). Row 3 (merge-test) — collapsed per `beta/SKILL.md` §Pre-merge gate: cycle diff is purely textual/docs and ships no new contract surface.

**Self-coherence quality:** Section ordering (`717cdba9` fix commit), peer enumeration, and non-goal verification are all explicit in self-coherence.md. Debt section explicitly states "None." α-side artifact is complete.
