# Post-Release Assessment — v3.49.0

## 1. Coherence Measurement

- **Baseline:** v3.48.0 — α A+, β A+, γ A+
- **This release:** v3.49.0 — α A+, β A, γ A+
- **Delta:** α held (dispatch boundary now mechanical). β dropped to A (no new architecture work — pure refactor). γ held (0 findings, clean extraction, first CI mechanicalization).
- **Coherence contract closed?** Yes. All 7 ACs met. 0 review findings.

## 2. Encoding Lag

| Issue | Title | Type | Design | Impl | Lag |
|-------|-------|------|--------|------|-----|
| #193 | Orchestrator llm step | feature | converged | not started | growing (12 cycles) |
| #186 | Package restructuring | feature | 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 Slices A-C done + cli extraction | low |
| #212 | Phase 3 remaining commands | feature | converged | Slice D remaining | low |

**MCI freeze:** active. 5 growing items unchanged. #221 closed this cycle.

## 3. Process Learning

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

**What went right:** 0 review findings — the extraction was mechanical and well-scoped. The CI dispatch boundary check is the first mechanicalized invariant, closing the prevention gap identified in the INVARIANTS.md analysis.

**Skill patches:** None needed.

## 4. Review Quality

**PRs this cycle:** 1 (#222)
**Avg review rounds:** 1 — target
**Finding breakdown:** 0 total
**Action:** none

### 4a. CDD Self-Coherence

All 4/4 across axes.

## 5. Production Verification

Deferred — requires binary deploy. Same binary, different internal structure. No behavior change.

### 6a. Invariants Check

| Constraint | Touched? | Status |
|---|---|---|
| T-002 Kernel remains minimal | Yes (primary target) | tightened — cli/ dispatch-only, CI enforced |
| INV-003 Distinct surfaces | No | N/A |
| P-001 Two-agent minimum | Yes | preserved — Claude authored, Sigma reviewed |
| P-002 Findings before merge | Yes | preserved — 0 findings |

## 7. Next Move

**Next MCA:** #212 Slice D — `update` + `setup`
**Owner:** Claude (implementor), Sigma (reviewer/releaser)
**MCI frozen until shipped?** Yes
