## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | Status truth table in issue accurately represents shipped vs not-present state; self-coherence §Gap consistent |
| Canonical sources/paths verified | yes | Three target files verified at canonical paths under `src/packages/cnos.cdd/skills/cdd/` |
| Scope/non-goals consistent | yes | Scope limited to three skill files in `cnos.cdd`; non-goals enumerate auto-tooling, SIGTERM model changes, schema changes — none present in diff |
| Constraint strata consistent | yes | Design constraints (no frontmatter, no new sub-skills, heuristic marked initial) all satisfied |
| Exceptions field-specific/reasoned | yes | `docs-only` disconnect path (§2.5b) correctly declared; no exceptions to hard gates |
| Path resolution base explicit | yes | All file paths in issue body and self-coherence use repo-relative paths resolvable from repo root |
| Proof shape adequate | yes | Issue proof plan includes oracles, positive/negative cases, and recursive-coherence check; all executed by β |
| Cross-surface projections updated | yes | operator §timeout-recovery and post-release §4 both updated as named docs in scope |
| No witness theater / false closure | yes | No CI badge checked; no "tests passed" on a docs-only cycle without justification; §Debt D4 explicitly reasons the absence |
| PR body matches branch files | n/a | CDD triadic protocol — no PR; branch + issue are the coordination surface |

## §2.0 Issue Contract

### AC Coverage

| # | AC | In diff? | Status | Notes |
|---|----|----------|--------|-------|
| AC1 | `§1.6c` added to CDD.md with 3 sub-rules (a)(b)(c) | yes | PASS | Oracle: 4 matches in order at lines 496, 500, 516, 525 |
| AC2 | operator/SKILL.md gains `§timeout-recovery` with `git status --short` and `git stash list` | yes | PASS | Section at line 268; commands at 280, 287; decision tree at §7.2 |
| AC3 | 3 telemetry fields in post-release §4 | yes | PASS | All 3 fields at lines 90–95; framing "optional initially; mandatory after ~10 cycles" satisfies honest framing AC |
| AC4 | 3 explicit cross-refs in §1.6c body | yes | PASS | §1.6b (line 498), post-release §4 (line 509), operator §timeout-recovery (lines 531, 533) |
| AC5 | Empirical anchors in §1.6c body | yes | PASS | cycle #335 at line 513; TSC supercycle at line 514; both with reproducible close-out paths |

### Named Doc Updates

| Doc / File | In diff? | Status | Notes |
|------------|----------|--------|-------|
| `CDD.md` §1.6c | yes | present | 39-line addition after §1.6b; no modification to §1.6a/§1.6b |
| `operator/SKILL.md` §timeout-recovery | yes | present | 56-line addition; §7 renamed, §8 is renamed embedded kata (1 deletion) |
| `post-release/SKILL.md` §4 telemetry fields | yes | present | 11-line addition within §4 |

### CDD Artifact Contract

| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| `self-coherence.md` | yes | yes | Full CDD Trace through step 7; review-readiness signal R1 present |
| `alpha-closeout.md` | yes | yes | Provisional per §Debt D2; standard for sequential bounded dispatch |
| `beta-review.md` | yes | this file | β writes on approval |
| `beta-closeout.md` | yes | to write | β writes post-merge |
| `cdd-iteration.md` | yes (≥1 cdd-gap finding) | yes | F1: `cdd-protocol-gap` — initial-dispatch-no-sizing-rule; disposition: patch-landed |
| `gamma-closeout.md` | yes | γ responsibility | Post-β; not yet written |

### Active Skill Consistency

| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| `cnos.core/skills/skill` | issue §Skills Tier 3 | yes (per self-coherence §Skills) | yes — no frontmatter changes across all 3 files | Design constraint satisfied |
| `cnos.eng/skills/eng/writing` | issue §Skills Tier 3 | yes | yes — prose patches applied consistently | Section headings, cross-refs, code blocks all coherent |

## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| F1 | self-coherence.md §Debt D1 and alpha-closeout.md §F1 state the heuristic for 5 ACs as "900s" (`5 × 120 + 300 = 900`), but the formula in §1.6c(a) is `max(300s, 120 × ac_count)` = max(300, 600) = **600s**. Both artifacts conclude budget (600s) < heuristic (900s), but the correct heuristic equals the budget exactly. The D1 debt declaration is based on wrong arithmetic. | self-coherence.md §Debt D1: "max(300, 120×5) = 900s"; alpha-closeout.md §F1: "900s for 5 ACs docs cycle"; CDD.md §1.6c(a) table: `max(300s, 120 × ac_count)` with floor 300s | A | honest-claim |

### Recursive Coherence Check (per issue proof plan + rule 3.13)

**Heuristic (docs cycle, 5 ACs):** `max(300s, 120 × 5)` = max(300, 600) = **600s**
**α dispatch budget (from self-coherence §Debt D1):** 600s
**Budget ≥ heuristic:** 600s ≥ 600s → **PASS**

The cycle's own dispatch exactly satisfied the heuristic it proposes. No recursive-coherence deficit exists. α's D1 debt declaration (claiming a deficit of 300s) is based on the arithmetic error documented in F1 above. Per dispatch instructions and rule 3.13 (non-blocking recursive coherence), F1 is noted but does not block approval.

## Regressions Required (D-level only)

None — no D-level findings.

## Notes

- **Operator/SKILL.md §7 renaming:** The Embedded Kata was §7; it is now §8. The new §7 is Timeout Recovery. One deletion in the diff is the old §7 heading (`-## 7. Embedded Kata`); the new heading (`+## 8. Embedded Kata`) appears correctly. This is a clean renumbering with no content loss.
- **Design constraints:** All four design constraints from the issue's "Active design constraints" section are satisfied: no frontmatter changes (verified), no new sub-skills (§7 is inline), heuristic marked "initial; refine with telemetry" (line 509 of CDD.md), cross-refs are normative (ring verified: §1.6c → §1.6b → operator §7 → post-release §4 → back to §1.6c(a)).
- **INDEX.md:** One row added for cycle #338. The pre-existing cycle #339 row is on origin/main (not in this diff — verified via `git diff --stat origin/main..origin/cycle/338`).
- **Pre-merge gate:** `scripts/validate-release-gate.sh --mode pre-merge` exited 0.
- **F1 severity rationale:** Error is confined to process artifacts (self-coherence.md, alpha-closeout.md). The shipped normative content (CDD.md §1.6c formula) is correct. The actual recursive coherence check passes. Per β/SKILL.md dispatch instructions, recursive coherence findings do not block approval. Classified A (polish) rather than C because the shipped skill content is coherent and the error has zero operational impact.
