# Post-Release Assessment — v3.47.0

## 1. Coherence Measurement

- **Baseline:** v3.46.0 — α A, β A+, γ A
- **This release:** v3.47.0 — α A, β A+, γ A
- **Delta:** held across all axes. Doctor command adds self-diagnosis capability. Design frontier advanced significantly (4 design docs/issues) but that's β maintenance, not improvement — the architecture was already explicit from v3.46.0.
- **Coherence contract closed?** Yes for Slice B. AC3, AC7, AC8, AC9 met. 2 findings found and fixed on-branch.

## 2. Encoding Lag

| Issue | Title | Type | Design | Impl | Lag |
|-------|-------|------|--------|------|-----|
| #193 | Orchestrator llm step | feature | converged | not started | growing (10 cycles) |
| #186 | Package restructuring | feature | converged (design doc shipped) | not started | growing |
| #175 | CTB → orchestrator IR compiler | feature | converged | not started | growing |
| #218 | cnos.transport.git | feature | design doc shipped | not started | growing |
| #216 | Kernel command migration | feature | design doc shipped | depends on Phase 4 | growing |
| #192 | Go kernel rewrite | feature | converged | Phase 3 in progress | low |
| #212 | Phase 3 remaining commands | feature | converged | Slices A+B done, C+D remaining | low |

**MCI/MCA balance:** **Freeze MCI** — 5 issues at growing lag (#193, #186, #175, #218, #216). Two new design issues filed this cycle (#216, #218) which adds to the growing backlog. However, #216 and #218 are explicitly sequenced after Phase 4 and are not actionable until the Go kernel ships. The operational priority remains: finish Phase 3, then Phase 4.

**Rationale:** MCI freeze remains active. The new design docs clarify existing architecture decisions rather than creating new speculative commitments — but they still add to the growing count. No new design docs until implementation catches up.

## 3. Process Learning

**What went wrong:** Nothing significant. Clean 2-round review cycle.

**What went right:** §7.0 gate continues to work. Both findings were fixed on-branch before merge. The F1 finding (optional file severity) is a good example of a judgment call that review catches — the code was correct but misleading.

**Skill patches:** None needed.

**Active skill re-evaluation:** F1 (optional file severity) — this is a UX judgment, not covered by eng/go skill. Not a skill gap. F2 (test assertion gap) — eng/go §2.8 covers test quality but doesn't specifically address "assert the happy path succeeds." Could sharpen but the finding was low severity (C). No patch needed.

**CDD improvement disposition:** No patch needed. Both findings were judgment-level, caught by review, fixed on-branch. The review skill's §2.2.10 (contract-implementation confinement) partially applies to F1 — the function's name ("optional") and its behavior (`passed: false`) disagreed. Existing coverage sufficient.

## 4. Review Quality

**PRs this cycle:** 1 (#217)
**Avg review rounds:** 2 (R1: 2 findings, R2: both fixed) — at target (≤2 for code)
**Superseded PRs:** 0
**Finding breakdown:** 1 judgment (F1) + 1 judgment (F2) / 0 mechanical / 2 total
**Mechanical ratio:** 0%
**Action:** none

### 4a. CDD Self-Coherence

- **CDD α:** 4/4 — all required artifacts present
- **CDD β:** 4/4 — design docs, code, assessment all agree
- **CDD γ:** 4/4 — 2 review rounds (at target), 0 superseded, findings fixed on-branch
- **Weakest axis:** none (all 4/4)
- **Action:** none

## 5. Production Verification

**Scenario:** `cn doctor` validates hub health on VPS
**Before this release:** no `doctor` command in Go binary
**After this release:** `cn doctor` checks prerequisites, hub structure, packages, runtime contract, git remote
**How to verify:**
```bash
ssh root@143.198.14.19 'cd /home/cn/cn-sigma && cn doctor'
```
**Result:** deferred — requires binary deploy (CI in progress)

## 6. CDD Closeout

| Step | Artifact | Skills loaded | Decision |
|------|----------|--------------|----------|
| 9 Review | PR #217 comments (R1 + R2) | review | 2 findings, both fixed on-branch |
| 10 Release | tag 3.47.0, RELEASE.md, CHANGELOG | release | v3.47.0 released at cc2da11 |
| 11 Observe | this assessment | post-release | doctor shipped, design frontier advanced |
| 12 Assess | POST-RELEASE-ASSESSMENT.md | post-release | assessment completed |
| 13 Close | next MCA below | post-release | cycle closed |

## 7. Next Move

**Next MCA:** #212 Slice C — `build` command
**Owner:** Claude (implementor), Sigma (reviewer/releaser)
**Branch:** `claude/go-212c-build`
**First AC:** AC4 — `cn build` builds packages from `packages/*/cn.package.json` source trees
**MCI frozen until shipped?** Yes
**Rationale:** 5 growing lag items. Continue shipping Go kernel phases.

**Closure evidence (CDD §10):**
- Immediate outputs executed: yes
  - Design docs committed (git-cn, package restructuring, capabilities, kernel migration)
  - Issues filed (#216, #218)
- Deferred outputs committed: yes
  - #212 Slices C+D remain open
  - Production verification deferred to deploy
