## Post-Release Assessment — v3.44.0

**Release commit:** `b5a91b3`
**Tag:** `3.44.0`
**Cycle:** #207 / PR #208 — Go purity boundary + OCaml skill v2 + architecture design docs
**Skill loaded:** `src/agent/skills/cdd/post-release/SKILL.md`
**Assessor role:** Reviewer (Sigma) — default releaser per CDD §1.4

### 1. Coherence Measurement

- **Baseline:** v3.43.0 — C_Σ A · α A · β A · γ A · L7
- **This release:** v3.44.0 — C_Σ A · α A+ · β A · γ A · L6
- **Delta:**
  - **α upgraded to A+.** The Go module now mirrors the OCaml purity split exactly: `Parse*` (pure, `[]byte`) in `internal/pkg/`, `Read*` (IO, path) in `internal/restore/`. This is the same discipline Move 2 established in OCaml. The command architecture design converged through 3 review iterations to a precise model: `CommandSpec` runtime descriptor, `Invocation` with IO streams, `cn.package.v1`-compatible kernel manifest.
  - **β held A.** Three eng skills converged at L6. Two design docs shipped and reviewed. No new β gaps introduced.
  - **γ held A.** Two-agent cycle on #208: 1 review round, 0 findings. Design doc iterated 3 times based on operator review — each iteration addressed concrete findings. CDD process executed cleanly.
  - **Level L6.** Cross-surface coherence: Go purity boundary now mirrors OCaml. No new system boundary (that was v3.43.0's L7).
- **Coherence contract closed?** **Yes.** All ACs met on #207. All 4 review findings from PR #206 addressed.

### 2. Encoding Lag

| Issue | Title | Type | Design | Impl | Lag |
|-------|-------|------|--------|------|-----|
| #192 | Runtime kernel rewrite: OCaml → Go | feature | 4-phase + design docs | Phase 1 complete, purity fixed | low |
| #209 | Go kernel Phase 2: CLI dispatch | feature | GO-KERNEL-COMMANDS v1.2 | not started | new |
| #193 | `llm` step execution + binding substitution | feature | needs design | not started | growing (8 cycles) |
| #186 | Package restructuring | feature | design thread exists | not started | growing |
| #175 | CTB → orchestrator IR compiler | feature | CTB-v4.0.0-VISION.md | blocked on #193 | growing |

**MCI/MCA balance:** **Freeze MCI continues.** 3 issues at growing lag (#193, #186, #175). #209 is new (design complete, impl not started). Next MCA: #209 implementation.

### 3. Process Learning

**What went wrong:** Nothing. Clean cycle.

**What went right:**
1. **Design doc convergence through review.** GO-KERNEL-COMMANDS.md went through 3 iterations (v1.0 → v1.1 → v1.2), each addressing concrete operator findings. The final design is significantly better than the first draft.
2. **Zero findings on #208.** All 4 findings from PR #206 addressed completely. The purity boundary is now real, not just claimed.
3. **Three eng skills converged.** OCaml joined Go and TypeScript at L6. Same standard across all three.
4. **Design before implementation.** The command architecture and LLM routing designs were captured before coding begins. #209 has a reviewed design doc to implement against.

**Skill patches:** None needed.

**CDD improvement disposition:** No patch needed. The cycle executed within all targets.

### 4. Review Quality

**PRs this cycle:** 1 (#208)
**Avg review rounds:** 1.0
**Superseded PRs:** 0
**Finding breakdown:** 0 total
**Mechanical ratio:** N/A
**Action:** none

### 4a. CDD Self-Coherence

- **CDD α:** 4/4
- **CDD β:** 4/4
- **CDD γ:** 4/4
- **Weakest axis:** none below 4
- **Action:** none

### 5. Production Verification

**Scenario:** `internal/pkg/` should have zero `os` imports.

**Before:** `pkg.go` imported `os` for `ReadLockfile`, `ReadPackageIndex`, `ValidatePackageManifest`.

**After:** `pkg.go` imports only `encoding/json` and `fmt`. IO functions live in `internal/restore/`.

**How to verify:** `grep -n '"os"' go/internal/pkg/pkg.go` → no matches.

**Result:** Pass.

### 6. CDD Closeout

| Step | Artifact | Skills loaded | Decision |
|------|----------|---------------|----------|
| 11 Observe | this assessment + PR #208 review (R1 APPROVED, 0 findings) | post-release | Cycle coherent. Purity boundary fixed. |
| 12 Assess | this file | post-release | C_Σ A · α A+ · β A · γ A · L6. MCI freeze continues. |
| 13 Close | this assessment + next-MCA commitment | post-release | Cycle closed. |

### 7. Next Move

**Next MCA:** #209 — Go kernel Phase 2: CLI entrypoint + modular command dispatch
**Owner:** Claude (author), Sigma (reviewer/releaser)
**Branch:** `claude/go-209-cli-dispatch`
**First AC:** AC1 — `go/cmd/cn/main.go` exists and builds
**MCI frozen until shipped?** Yes — 3 growing (#193, #186, #175).
**Rationale:** #209 has a reviewed design doc (GO-KERNEL-COMMANDS.md v1.2). Implementation can begin immediately. This produces the first runnable Go binary (`cn deps restore`).

**Closure evidence (CDD §10):**
- Immediate outputs executed: this assessment, CHANGELOG, RELEASE.md, branch cleanup
- Deferred: #209 (next MCA)

### 8. Hub Memory

- **Daily reflection:** pending
- **Adhoc thread(s) updated:** pending — go-kernel-rewrite thread
