## Post-Release Assessment — v3.45.0

**Release commit:** `7175406`
**Tag:** `3.45.0`
**Cycle:** #209 / PR #210 + PR #211 — Go kernel Phase 2: CLI dispatch + CDD §7.0 gate
**Skill loaded:** `src/agent/skills/cdd/post-release/SKILL.md`
**Assessor role:** Reviewer (Sigma) — default releaser per CDD §1.4

### 1. Coherence Measurement

- **Baseline:** v3.44.0 — C_Σ A · α A+ · β A · γ A · L6
- **This release:** v3.45.0 — C_Σ A · α A+ · β A · γ A · L7
- **Delta:**
  - **α held A+.** The CLI architecture implements GO-KERNEL-COMMANDS.md v1.2 faithfully: `CommandSpec` with all fields, `Invocation` with IO streams, `Command` interface with `Spec()` + `Run()`, `Registry` with tier precedence and `Available(hasHub)`. The design-to-implementation gap is zero.
  - **β held A.** 20 tests across 3 packages. Hub discovery, availability filtering, tier precedence all tested.
  - **γ held A.** Two-agent cycle: 1 review round on #210 (3 findings), findings fixed in #211 before merge. First validation of §7.0 gate. CDD process executed cleanly.
  - **Level L7.** New subsystem (`internal/cli/`) with command dispatch architecture. First runnable Go binary.
- **Coherence contract closed?** **Yes.** All 9 ACs met. All 3 findings resolved on-branch.

### 2. Encoding Lag

| Issue | Title | Type | Lag |
|-------|-------|------|-----|
| #193 | `llm` step execution | feature | growing (8 cycles) |
| #186 | Package restructuring | feature | growing |
| #175 | CTB compiler | feature | growing (blocked #193) |
| #192 | Go kernel (umbrella) | feature | low (Phase 1+2 complete) |

**MCI freeze continues.** 3 growing (#193, #186, #175).

### 3. Process Learning

**What went right:**
1. **§7.0 gate validated on first use.** PR #210 had 3 B-level findings. Under the old process, these would have shipped as follow-up issues. Instead, Claude pushed fixes on `go-210-fix-findings` branch, reviewed and merged in the same cycle. Zero additional overhead vs. the old "file issue + new branch + new review" pattern.
2. **Design doc → implementation fidelity.** GO-KERNEL-COMMANDS.md v1.2 (3 review iterations) produced a clean implementation with 0 C/D findings. The design investment paid off.
3. **20 Go tests across 3 packages.** Test coverage growing proportionally with code.

**Skill patches:** CDD §7.0 shipped this cycle (review skill + CDD.md + cnos.core).

### 4. Review Quality

**PRs this cycle:** 2 (#210, #211)
**Avg review rounds:** 1.0 each
**Finding breakdown:** 3 total on #210 (1A + 2B), 0 on #211
**Mechanical ratio:** 67% (2/3) — above 20% threshold
**Action:** The B-level findings (reimplemented `strings.Join`, unnecessary env copy) are the same class as PR #206 F1 (`strings.Contains`). This is a recurring pattern from Claude: reimplementing stdlib functions. The §7.0 gate now catches these before merge, but the root cause is still present. Consider adding "use stdlib before reimplementing" to eng/go skill as an explicit rule.

### 4a. CDD Self-Coherence

All 4/4 on α, β, γ. No action needed.

### 5. Production Verification

**Scenario:** `go build ./cmd/cn && ./cn help` shows registered commands.

**How to verify:** Build binary, run in a hub directory and outside one.
- In hub: shows `help` + `deps`
- Outside hub: shows `help` only + ⚠ warning

**Result:** Pass (CI builds binary, local smoke test verified per PR body).

### 6. CDD Closeout

| Step | Artifact | Skills loaded | Decision |
|------|----------|---------------|----------|
| 11 | this assessment | post-release | Cycle coherent. First Go binary ships. |
| 12 | this file | post-release | C_Σ A · α A+ · β A · γ A · L7. MCI freeze continues. |
| 12a | §7.0 gate | review, cdd | Findings-before-merge gate landed same session. |
| 13 | this assessment | post-release | Cycle closed. |

### 7. Next Move

**Next MCA:** eng/go skill patch — add "use stdlib before reimplementing" rule to address recurring B-level finding class. Then #192 Phase 3 (remaining kernel commands: doctor, status, update, init, setup, build).

**Closure evidence (CDD §10):**
- Immediate outputs executed: this assessment, CHANGELOG, RELEASE.md, branch cleanup, hub memory (pending below)
- Deferred: Phase 3 issue, eng/go skill patch

### 8. Hub Memory

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