## Post-Release Assessment — 3.56.0

### 1. Coherence Measurement
- **Baseline:** 3.55.0 — α A-, β A, γ A-
- **This release:** 3.56.0 — α A, β A-, γ A-
- **Delta:** α improved to A (zero-finding cycle, self-coherence applied at authoring time, design pre-converged). β dropped to A- (clean review but failed to produce post-release assessment — closure gap recurring from 3.55.0; also, squash-merge destroyed α's close-out artifact on the PR branch). γ held at A- (dispatched correctly, but did not enforce closure artifact collection from β — same pattern as 3.55.0).
- **Coherence contract closed?** Yes. `cn <noun> <verb>` is now the primary command surface. DESIGN-CONSTRAINTS §3.1 is mechanized. Flat-hyphenated forms preserved as backward-compat fallback.

### 2. Encoding Lag

| Issue | Title | Type | Design | Impl | Lag |
|-------|-------|------|--------|------|-----|
| #253 | ContentClasses divergence (8 vs 5) | bug | converged | not started | growing |
| #250 | cn deps lock over-install | bug | design exists | not started | growing |
| #249 | .cdd/ Phase 1 audit trail | feature | converged | partially started | low |

**MCI/MCA balance:** **Freeze MCI** — 11 issues at "growing" lag, well over the 3-issue threshold. No new design work until MCA backlog is reduced.
**Rationale:** Growing-lag count increased from 7 (3.55.0) to 11. The project needs to ship, not design. Priority MCAs: #253 (ContentClasses, small fix), #250 (deps lock, bug), #235 (build --check, P1).

### 3. Process Learning

**What went wrong:**
- β failed to produce post-release assessment. This is the same pattern from 3.55.0 — β's session ends or β doesn't reach step 9. Third time closure artifacts have required intervention (3.55.0 γ escalation, 3.55.0 β verbal-only close-out, 3.56.0 β no assessment at all).
- Squash-merge destroyed α's close-out artifact. α correctly committed `.cdd/releases/3.56.0/alpha/254.md` to the PR branch per step 11. GH squash-merge only included code files in the squash — the `.cdd/` file was orphaned when the branch was deleted. Had to be recovered manually.
- γ did not enforce β closure before moving on.

**What went right:**
- α delivered a zero-finding L6 cycle. Design pre-converged in DESIGN-CONSTRAINTS §3.1 before the implementation cycle — α was pure MCA, no mid-cycle design divergence.
- α correctly used git identity (`alpha <alpha@cdd.cnos>`).
- α's close-out was thorough and honest — recorded what worked as a counter-example to #251 drift, documented the lookup-order design decision and .gitignore quirk as non-findings.
- 1 review round, 0 findings — evidence that §2.5b self-coherence was applied at authoring time.

**Skill patches:** One process finding requires a spec patch:

1. **CDD §1.4 α algorithm step 11:** Close-out artifacts must be committed to main directly, not on the PR branch. Squash-merge does not preserve branch-only artifacts. Patch: add note to step 11: *"Commit close-out to main (not the PR branch) — squash-merge destroys branch-only files."*

**Active skill re-evaluation:**
- No review findings to evaluate (0 findings).
- The closure artifact loss is a process/tooling gap, not a review gap.

**CDD improvement disposition:** Patch needed for §1.4 step 11 (close-out commit target). Shipped in this commit.

### 4. Review Quality

**PRs this cycle:** 1 (#257)
**Avg review rounds:** 1.0 (target: ≤2 code) ✅
**Superseded PRs:** 0 ✅
**Finding breakdown:** 0 mechanical / 0 judgment / 0 total
**Mechanical ratio:** n/a (0 findings)
**Action:** none

### 4a. CDD Self-Coherence
- **CDD α:** 4/4 — all artifacts present, self-coherence applied at authoring time, close-out written (recovered to main)
- **CDD β:** 2/4 — clean review and merge, but no post-release assessment produced; squash-merge destroyed branch artifact
- **CDD γ:** 2/4 — dispatch correct, but did not enforce β closure; same failure as 3.55.0 without mechanism change
- **Weakest axis:** β and γ tied
- **Action:** Patch §1.4 step 11 (close-out to main). The β closure enforcement gap remains an application problem — the spec says to do it, β doesn't. Candidate MCA: make `cn cdd-verify` a pre-release gate (β cannot tag until artifacts pass verification). Deferred to next cycle as it requires code change.

### 5. Production Verification

**Scenario:** `cn <noun> <verb>` dispatch resolves correctly; flat forms preserved.
**Before this release:** Only flat-hyphenated commands worked (`cn kata-run`). No noun grouping, no `cn help <noun>`.
**After this release:** `cn kata run` resolves to `kata-run`. `cn help kata` lists all kata verbs. Flat forms still work.
**How to verify:** CI exercised all 14 dispatch test cases + 2 help tests. `kata-tier1`, `kata-tier2` both green using existing flat command names (backward compat confirmed).
**Result:** Pass — CI 7/7 green on release commit `ea84c8ed`.

### 6. CDD Closeout

| Step | Artifact | Skills loaded | Decision |
|------|----------|--------------|----------|
| 0–1 | #254 issue | cdd | γ selected git-style subcommands |
| 2–7 | PR #257 | cdd, eng/go, eng/ux-cli | α implemented dispatch |
| 7a | Pre-review | cdd | CI green, self-coherence done (0 gaps) |
| 8 | Review R1 | cdd, review | β: APPROVED with 0 findings |
| 9 | Merge | release | β: squash-merged |
| 10 | Release | release | σ: release commit `ea84c8ed`, tag `3.56.0` |
| 11–12 | This assessment | post-release | σ (completing for β) |
| 12a | Skill patch | cdd | §1.4 step 11 close-out-to-main (this commit) |
| 13 | Close | post-release | α close-out: `.cdd/releases/3.56.0/alpha/254.md`. β close-out: not produced. σ assessment: this file. |

### 6a. Invariants Check

| Constraint | Touched? | Status |
|---|---|---|
| T-002 (dispatch boundary) | yes — dispatch.go added to cli/ | preserved (CI grep green) |
| T-003 (stdlib only) | no | N/A |
| T-005 (finite content classes) | no | N/A |
| INV-001 (single manifest format) | no | N/A |
| INV-003 (commands/skills/orchestrators distinct) | no | N/A |

### 7. Next Move
**Next MCA:** #253 — ContentClasses divergence (8 vs 5)
**Owner:** α (via γ dispatch)
**Branch:** pending
**First AC:** `pkgbuild.ContentClasses` matches filesystem reality
**MCI frozen until shipped?** Yes
**Rationale:** Bug fix, small diff, directly reduces incoherence between code and filesystem. Followed by #250 and #235 (both P1/bug).

**Closure evidence (CDD §10):**
- Immediate outputs executed: yes
  - §1.4 step 11 patch (this commit)
  - Release: tag 3.56.0 pushed, CI green, GH release created
- Deferred outputs committed: yes
  - `cn cdd-verify` as pre-release gate → candidate for next cycle, not filed yet (needs code change)

**Immediate fixes** (executed in this session):
- §1.4 step 11: close-out to main note (see below)

### 8. Hub Memory
- **Daily reflection:** deferred — σ does not have write access to cn-sigma hub threads from this context
- **Adhoc thread(s) updated:** n/a — σ completing for β; hub memory is σ's responsibility in σ's own session
