## §2.0.0 Contract Integrity

| Check | Result | Notes |
|---|---|---|
| Status truth preserved | yes | self-coherence.md `status: review-ready`; issue still OPEN — both correct |
| Canonical sources/paths verified | yes | All 5 changed files exist on branch at expected paths; cross-references to `operator/SKILL.md §Git identity for role actors` resolvable |
| Scope/non-goals consistent | yes | Diff contains only the 5 files enumerated in self-coherence.md §ACs; no code changes; out-of-scope items (history rewrite, branch rename, GPG) not touched |
| Constraint strata consistent | yes | No contradictions between CDD.md §1.4 identity lines, operator/SKILL.md prescription, alpha/SKILL.md gate row 14, review/SKILL.md cross-reference |
| Exceptions field-specific/reasoned | n/a | Docs-only cycle; no exceptions needed |
| Path resolution base explicit | yes | Self-coherence §ACs cites specific line ranges; cross-references name section headers |
| Proof shape adequate | yes | Each AC has oracle + positive check; honest-claim verification applicable to docs claims |
| Cross-surface projections updated | yes | All five surfaces identified in issue scope updated; gamma/SKILL.md verified as non-prescriptive (delegates identity to §2.0 reference, no direct email form) |
| No witness theater / false closure | yes | Self-coherence claims are backed by diff evidence; ambiguity in AC1 oracle documented and resolved by α |
| PR body matches branch files | n/a | Triadic protocol — no PR; `.cdd/unreleased/343/` is the coordination surface |

## R1 — Pass 2: Implementation Review

### §2.0 Issue Contract

#### AC Coverage

| # | AC | In diff? | Status | Notes |
|---|----|----------|--------|-------|
| AC1 | `operator/SKILL.md` §Git identity prescribes `{role}@{project}.cdd.cnos`, 2–4 sentence rationale | yes | met | Prescription added at lines 52–76; 2-sentence rationale covers DNS hierarchy + cnos-as-origin |
| AC2 | cnos special-case resolved; elision form `{role}@cdd.cnos` named as canonical; one form, no ambiguity | yes | met | `operator/SKILL.md` lines 55–56 document the elision and its rationale; worked example table row 2 confirms the choice; no "either is fine" text |
| AC3 | 3–5 row worked example table; deprecated row marked | yes | met | 4-row table in `operator/SKILL.md` lines 58–64; rows: `alpha@tsc.cdd.cnos`, `beta@cdd.cnos` (elision), `gamma@acme.cdd.cnos`, `beta@cdd.{project}` **(deprecated)**; table reachable from CDD.md §Parameters inline cross-reference |
| AC4 | `post-release/SKILL.md` §Identity migration subsection; ≤80 words; names cycle #343 + date | yes | met | Section added; word count 70 (≤80 ✓); names cycle #343; cutover date 2026-05-11; no expectation of history rewrite |
| AC5 | Commits on cycle/343 use new form; `git log --format='%ae' cycle/343` shows only canonical form | yes | met | Branch commits: `alpha@cdd.cnos` (α commits `0757c9be`, `d0f69a0f`) and `gamma@cdd.cnos` (γ scaffold commits); no old `@cdd.{project}` form |

#### Named Doc Updates

| Doc / File | In diff? | Status | Notes |
|------------|----------|--------|-------|
| `cdd/operator/SKILL.md` — new §Git identity section | yes | present | Primary prescription site; added before §1. Route |
| `cdd/review/SKILL.md` — §Review identity | yes | present | Old `beta@cdd.{project}` doctrine replaced with cross-reference to `operator/SKILL.md §Git identity for role actors` |
| `cdd/alpha/SKILL.md` — pre-review gate row 14 | yes | present | Updated `alpha@cdd.{project}` → `alpha@{project}.cdd.cnos` with cnos elision note |

| `cdd/post-release/SKILL.md` — §Identity migration | yes | present | Migration note added before Kata section |
| `cdd/beta/SKILL.md` | not in diff | n/a | Pre-merge gate row 1 already uses `beta@cdd.cnos` (canonical elision); no change needed |
| `cdd/gamma/SKILL.md` | not in diff | n/a | Delegates identity to §2.0 reference; no direct email form prescribed; verified via grep |
| `cdd/issue/contract/SKILL.md` | not in diff | n/a | Uses `alpha@cdd.cnos` (canonical cnos elision form); already correct |

#### CDD Artifact Contract

| Artifact | Required? | Present? | Notes |
|----------|-----------|----------|-------|
| `self-coherence.md` | yes | yes | Review-readiness signal confirmed; AC-by-AC evidence; CDD Trace through step 7 |
| `beta-review.md` | yes | yes (in progress) | This file |
| `alpha-closeout.md` | yes (post-merge) | not yet | Post-merge step; expected after β close-out |
| `beta-closeout.md` | yes (post-merge) | not yet | β writes after merge |

#### Active Skill Consistency

| Skill | Required by | Loaded? | Applied? | Notes |
|-------|-------------|---------|----------|-------|
| `alpha/SKILL.md` | Tier 1 | yes | yes | Pre-review gate row 14 updated per skill surface |
| `CDD.md` | Tier 1 | yes | yes | 4 identity setup lines updated |

### §2.1 Diff and Context Inspection

**2.1.2 Multi-format parity:** The three-level form `{role}@{project}.cdd.cnos` is applied consistently across all 5 changed surfaces. The cnos elision `{role}@cdd.cnos` is consistently named as the special case in every site that prescribes the form. No format divergence found.

**2.1.4 Stale-path validation:** The deprecated two-level form `@cdd.{project}` was checked across `src/packages/cnos.cdd/skills/cdd/` via `rg '@cdd\.'`. Remaining matches: two occurrences — `operator/SKILL.md:63` (deprecated-example row, explicitly marked **(deprecated)**) and `post-release/SKILL.md:472` (migration paragraph, naming it as the deprecated form). No prescriptive survivors. The canonical elision `@cdd.cnos` also matches the pattern; all those matches are correct uses of the new convention.

**2.1.5 Branch naming:** `cycle/343` — correct per CDD.md §4.2 convention.

**2.1.8 Authority-surface conflict:** All five updated surfaces are consistent: `operator/SKILL.md` (canonical home), `CDD.md` (cross-references operator), `review/SKILL.md` (cross-references operator), `alpha/SKILL.md` (prescribes per operator), `post-release/SKILL.md` (migration note). No conflict found.

**Honest-claim verification (3.13):**
- (a) Reproducibility: docs-only cycle; no measurements claimed. N/A.
- (b) Source-of-truth alignment: The term "DNS domains read broad-to-narrow right-to-left" is stated without citation but is normative RFC convention (RFC 1034 §3.1 cited in the issue's references section). The claim is accurate and widely verifiable. ✓
- (c) Wiring claims: `review/SKILL.md` §Review identity says "see `operator/SKILL.md` §Git identity for role actors." The section exists at that path. ✓ CDD.md §Parameters says "see `operator/SKILL.md` §Git identity for role actors." Section verified present. ✓

### §2.2 Architecture Check

| Check | Result | Notes |
|---|---|---|
| Reason to change preserved | n/a | Docs-only; no module/code boundaries affected |
| Policy above detail preserved | n/a | Protocol policy change lives in `operator/SKILL.md` (correct policy-level placement) |
| Interfaces remain truthful | n/a | No code interfaces changed |
| Registry model remains unified | n/a | No registry changes |
| Source/artifact/installed boundary preserved | n/a | No build artifacts affected |
| Surface separation preserved | n/a | No skill/command/orchestrator lines crossed |
| Degraded-path visibility | n/a | No degraded paths introduced |

## Findings

| # | Finding | Evidence | Severity | Type |
|---|---------|----------|----------|------|
| — | No findings | — | — | — |

**Observation (not a finding, not actionable on branch):** The AC1 issue-body oracle `rg '@cdd\.' cdd/` as stated would return matches outside migration/history blocks because the canonical cnos elision `@cdd.cnos` also matches `@cdd\.`. The underlying AC intent (no prescriptive use of the old two-level `@cdd.{project}` form) is satisfied. α documented this ambiguity in self-coherence §Self-check. The specific negative oracle (`rg 'beta@cdd\.{project}' review/SKILL.md` → 0 hits) passes cleanly. The broader oracle in the issue body is imprecise but the AC is coherently met; nothing on the branch can fix the issue spec wording.

## Regressions Required (D-level only)

None.

## Notes

Docs-only cycle. No executable tests; no CI checks to verify. All five targeted surfaces updated, three untouched surfaces verified correct by inspection. Peer enumeration complete. No surviving prescriptive instances of the deprecated `{role}@cdd.{project}` form.

---

## R1 — Pass 3: Verdict

**Verdict:** APPROVED

**Round:** 1
**Fixed this round:** n/a (first round, no prior findings)
**Branch CI state:** docs-only — no executable CI; not applicable
**Merge instruction:** `git merge --no-ff cycle/343` into main with `Closes #343` in the merge commit

### Summary

The cycle coherently resolves the namespace inversion in CDD identity convention. All five ACs are met:

- **AC1:** `operator/SKILL.md` §Git identity for role actors is the canonical prescription site with a 2-sentence DNS-hierarchy + cnos-as-origin rationale. ✓
- **AC2:** Elision form `{role}@cdd.cnos` is the unambiguous choice for cnos-side actors; one form prescribed, no fallback. ✓
- **AC3:** 4-row worked example table in `operator/SKILL.md` covers tsc/cnos/acme/deprecated; deprecated row marked; table reachable from CDD.md §Parameters. ✓
- **AC4:** `post-release/SKILL.md` §Identity migration subsection present; 70 words (≤80); names cycle #343 and cutover date 2026-05-11; no history-rewrite expectation. ✓
- **AC5:** All cycle/343 commits carry `alpha@cdd.cnos` (α) or `gamma@cdd.cnos` (γ) — new canonical elision form throughout. ✓

No D, C, B, or A findings. The AC1 oracle imprecision (noted as observation) is not actionable on the branch and does not affect merge readiness. The implementation is coherent.

β closes the search space: no blocker found across contract integrity, issue contract walk, diff/context inspection, or architecture check.
