## Post-Release Assessment — 3.55.0

### 1. Coherence Measurement
- **Baseline:** 3.54.0 — α A, β A, γ A
- **This release:** 3.55.0 — α A-, β A, γ A-
- **Delta:** α dropped to A- (one mechanical finding F2 reached review — dual-source `Kata Class:` lines in M0/M4 kata.md; cycle capped at L5 per §9.1). β held at A (clean 2-round review, all findings addressed in one narrowing round). γ dropped to A- (γ accepted β's "no tag cut" without challenge — cycle stalled until operator escalated; γ also skipped collecting α close-out until prompted).
- **Coherence contract closed?** Yes. Kata framework and CDD content are cleanly separated. `cnos.kata` owns the framework; `cnos.cdd.kata` owns method content. `katas/` is the 8th content class. Every command name follows the git-style subcommand convention (design-level; dispatch implementation deferred to #254).

### 2. Encoding Lag

| Issue | Title | Type | Design | Impl | Lag |
|-------|-------|------|--------|------|-----|
| #254 | Git-style subcommands | feature | converged | not started | new |
| #253 | ContentClasses divergence (8 vs 5) | bug | converged | not started | new |
| #249 | .cdd/ Phase 1 audit trail | feature | converged | partially started | low |
| #256 | CI as triadic surface | feature | converged | not started | new |
| #255 | CDD 1.0 master | tracking | converged | in progress | — |
| #244 | kata 1.0 master | tracking | converged | in progress | — |
| #245 | cdd-kata 1.0 (prove CDD adds value) | feature | converged | stubs only | growing |
| #243 | cnos.cdd.kata cleanup | feature | converged | partially done | low |
| #238 | Smoke: release bootstrap | feature | converged | not started | growing |
| #235 | cn build --check validates entrypoints | feature | converged | not started | growing |
| #230 | cn deps restore version upgrade skip | bug | design exists | not started | growing |
| #250 | cn deps lock over-install | bug | design exists | not started | new |
| #242 | .cdd/ directory layout | design | converged | not started | low |
| #240 | CDD triadic protocol | design | converged | not started | growing |
| #241 | DID: triadic identity | design | converged | not started | growing |
| #192 | Runtime kernel rewrite (Go) | feature | converged | Phase 4 complete | growing |
| #216 | Migrate commands to packages | feature | converged | not started | growing |
| #193 | Orchestrator llm step execution | feature | converged | not started | growing |

**MCI/MCA balance:** This cycle was MCA-heavy — 3 skill patches shipped from α close-out triage, 8 stale-reference fixes from β review, sub-skill normalization. Good. Continue MCA focus: #254 and #253 are small concrete fixes.
**Rationale:** Growing-lag count still high (7 issues). Stay on MCA: ship #254 (subcommands), #253 (ContentClasses), #249 (.cdd/ Phase 1) before opening new design.

### 3. Process Learning

**What went wrong:**
- γ accepted β's "no tag cut" decision without challenge. β decides *how* to release, not *whether*. γ owns the cycle — no tag = no assessment = cycle stuck open. Operator had to escalate.
- γ did not collect α close-out proactively. α committed it (`d104e44`) but γ only triaged it when prompted.
- β could not push tags (Claude Code sandbox limitation). This blocked the release until γ intervened. Known constraint from 3.54.0 — still not mechanized.

**What went right:**
- First real triadic CDD cycle with all three roles active on #251/#252.
- α correctly flagged architectural tension between #251 and #237 before coding. Used tool prompts to surface design questions for γ.
- Clean 2-round review: 3 findings (C, C, B) all addressed in one narrowing round.
- All 3 α close-out MCAs triaged and shipped immediately by γ — no deferred "noted for later."
- β's CDD package review (8 findings) caught comprehensive stale-path drift across the skill tree.
- `cn cdd-verify` command shipped and immediately exposed missing artifacts.

**Skill patches:** 5 patches shipped this cycle:
1. §7a schema/shape audit: deletion-verification required (`9ed4d68`)
2. §7a post-patch re-audit of PR body against HEAD (`9ed4d68`)
3. eng/testing §3.13: L7 refactors must CI-gate every new surface (`9ed4d68`)
4. α and β subscribe to issue/PR on startup, step 3 (`6407c43`)
5. 8 stale-path/reference fixes across CDD skill tree (`d98b4dc`, `dde8b4f`)

**Active skill re-evaluation:**
- CDD §7a (pre-review): strengthened with deletion-verification and post-patch re-audit. Previously permitted addition-only audits.
- eng/testing: new §3.13 covers L7 refactor surface coverage gap.
- CDD §1.4: α/β subscribe step added. Previously no instruction to monitor notifications.
- review/SKILL.md: verdict numbering fixed to monotonic 2.3.1–2.3.9. Previously had duplicates and out-of-order.

**CDD improvement disposition:** All patches landed in this release (not deferred).

### 4. Review Quality

**PRs this cycle:** 1 (#252)
**Avg review rounds:** 2.0 (target: ≤2 code) ✅
**Superseded PRs:** 0 ✅
**Finding breakdown:** 1 mechanical (F2) / 2 judgment (F1, F3) / 3 total
**Mechanical ratio:** 33% (threshold: 20% → §9.1 triggered) ⚠️
**Action:** §9.1 cycle iteration completed. 3 MCAs shipped. Cycle capped at L5.

Additionally, β conducted a CDD package review (not PR-scoped) producing 8 findings across the skill tree — all severity D or C, all fixed.

### 4a. CDD Self-Coherence
- **CDD α:** 3/4 — artifact integrity good; one mechanical finding (dual-source) reached review
- **CDD β:** 4/4 — clean 2-round review, all surfaces checked, comprehensive package-level review
- **CDD γ:** 3/4 — failed to challenge "no tag cut," delayed collecting α close-out
- **Weakest axis:** α and γ tied
- **Action:** γ algorithm compliance — γ must enforce step 9 (cycle closes only when assessment committed) without operator escalation. Filed no new issue — the mechanism is already in the spec; this was an application gap.

### 5. Production Verification

**Scenario:** Kata framework discovers and runs katas from separate packages.
**Before this release:** `cn kata-run` only existed in `cnos.cdd.kata`. Runtime and method katas mixed in one package.
**After this release:** `cnos.kata` owns framework + R1-R4; `cnos.cdd.kata` owns M0-M4 content. `cn kata-run --class runtime` discovers katas across packages.
**How to verify:** `cn kata-run --class runtime` (CI job `kata-tier2` runs this).
**Result:** Pass — CI green on merge commit `2b5611b` and all subsequent commits.

### 6. CDD Closeout

| Step | Artifact | Skills loaded | Decision |
|------|----------|--------------|----------|
| 0–1 | #251 issue | cdd | γ selected kata framework refactor |
| 2–7 | PR #252 | cdd, eng/tool-writing, eng/testing, eng/ship | α implemented framework split |
| 7a | Pre-review | cdd | CI green, self-coherence done (with F2 gap) |
| 8 | Review R1 | cdd, review | β: RC with 3 findings |
| 8 | Review R2 | cdd, review | β: APPROVED |
| 9 | Merge | release | β: squash-merged as `2b5611b` |
| 10 | Release | release | β: release commit `b1cf379`, γ: tag `3.55.0` |
| 11–12 | This assessment | post-release | β (completed by γ) |
| 12a | Skill patches | cdd, post-release | 5 patches shipped (see §3) |
| 13 | Close | post-release | α close-out: `.cdd/releases/3.55.0/alpha/251.md`. β close-out: verbal (no new findings). γ close-out: `.cdd/releases/3.55.0/gamma/CLOSE-OUT.md` |

### 6a. Triadic close-out summary

| Role | Close-out | Findings | MCAs shipped |
|------|-----------|----------|-------------|
| α | `.cdd/releases/3.55.0/alpha/251.md` | 3 (deletion-verification, post-patch re-audit, L7 coverage) | 3/3 |
| β | verbal to γ | 0 new (clean R2) | — |
| γ | `.cdd/releases/3.55.0/gamma/CLOSE-OUT.md` | 2 process gaps (tag-cut challenge, close-out collection) | application gaps, no new mechanism needed |

### Pre-publish gate

- [x] Version strings agree (CHANGELOG, tag, cn.package.json for cnos.kata 0.2.0 + cnos.cdd.kata 0.3.0)
- [x] §3/§4 skill patches in this commit and synced across affected surfaces
- [x] No D-level findings remaining
- [x] Kata CI green
- [ ] `cn cdd-verify --version 3.55.0 --triadic` — partial pass (γ CLOSE-OUT exists; β ASSESSMENT is this file; KATA-VERDICT deferred)
