## Post-Release Assessment — 3.52.0

### 1. Coherence Measurement
- **Baseline:** 3.51.0 — alpha A, beta A, gamma A-
- **This release:** 3.52.0 — alpha A, beta A, gamma A-
- **Delta:** alpha held (new package boundary clean, types pure, tests comprehensive). beta held (three source forms normalize into one model — design doc and implementation agree). gamma held at A- (1 review round, 4 findings all fixed on-branch; tag push blocked by sandbox — environmental, not process).
- **Coherence contract closed?** Yes. The "one model" promise from GO-KERNEL-COMMANDS.md Phase 4 is realized: kernel, repo-local, and package commands share the same `CommandSpec`, `Registry`, and `Command` interface. `cn daily` dispatches from an installed package. The gap "8 kernel commands visible, package commands invisible" is closed.

### 2. Encoding Lag

| Issue | Title | Type | Design | Impl | Lag |
|-------|-------|------|--------|------|-----|
| #192 | Runtime kernel rewrite (Go) | feature | converged | Phase 4 shipped (this release), Phase 5 remains | low |
| #216 | Migrate non-bootstrap commands to packages | feature | converged | depends on Phase 4 (now unblocked) | growing |
| #193 | Orchestrator llm step execution | feature | converged | not started | growing |
| #186 | Package restructuring (lean cnos.core) | feature | converged | not started | growing |
| #218 | cnos.transport.git (Rust provider) | feature | converged | not started | growing |
| #190 | Agent web surface | feature | design exists | not started | growing |
| #189 | Native change proposals + reviews | feature | design exists | not started | growing |
| #230 | cn deps restore version upgrade skip | feature | design exists | not started | low |
| #199 | Stacked post-release assessments (3.39+3.40) | process | converged | not started | growing |

**MCI/MCA balance:** **Freeze MCI** — 6 issues at "growing" lag (#216, #193, #186, #218, #190, #189). Exceeds the >=3 threshold.
**Rationale:** Design frontier is far ahead of implementation. MVA sprint (#228) is the correct focus — Steps 3 (this release) and 4 (#192 AC4) close the pipeline. No new substantial design docs until the MVA pipeline is complete and growing-lag count drops below 3.

### 3. Process Learning
**What went wrong:** Tag push blocked by sandbox environment (403 on refs/tags/). Release commit is on main but tag could not be created via git push. Not a process gap — environmental constraint.

**What went right:** Review findings were all fixable on-branch in a single session. The architecture check (section 2.2.14) proved its value — it confirmed all 7 design-principles questions passed, giving confidence that the new `discover/` package respects existing boundaries. The path confinement finding (F3) was caught by systematic application of eng/go section 3.10 — the review skill's contract-implementation confinement check (section 2.2.10) flagged the unvalidated entrypoint path.

**Skill patches:** None needed this cycle.

**Active skill re-evaluation:**
- F1 (dead code duplication): eng/go section 3.9 smell list includes "producer-owned interfaces with one implementation" but not "dead exported functions." However, review skill section 2.2.1 (sibling consistency) would catch this if applied to exports — the discover package has `ValidateCommands` but the production path uses `doctor.ValidateCommands`. The review skill is adequate; this was caught by applying it.
- F2 (sortStrings reimplements stdlib): eng/go section 2.11 explicitly covers this. Application gap — the rule exists, the author didn't follow it.
- F3 (path confinement): review skill section 2.2.10 (contract-implementation confinement) caught it. Skill adequate.
- F4 (unwrapped error): eng/go section 2.5 covers error wrapping. Application gap.

**CDD improvement disposition:** No patch needed. All 4 findings were caught by existing skill rules (eng/go section 2.5, section 2.11, section 3.10; review skill section 2.2.10). The failures were application gaps (author didn't follow rules that exist), not skill gaps (rules don't exist). No recurring mechanical failure class emerged.

### 4. Review Quality
**PRs this cycle:** 1 (PR #231)
**Avg review rounds:** 1.0 (target: <=2 code)
**Superseded PRs:** 0 (target: 0)
**Finding breakdown:** 1 mechanical / 3 judgment / 4 total
**Mechanical ratio:** 25% (threshold: 20%)
**Action:** The mechanical finding (F2: sortStrings reimplements stdlib) is a single instance in a small sample. The eng/go section 2.11 rule already covers it ("Do not reimplement stdlib functions"). A pre-flight grep for hand-rolled sort/contains/join in new Go files could catch this mechanically, but the ROI is low given this is the first occurrence. Noting for pattern — if it recurs next cycle, file a process issue for a pre-commit check.

### 4a. CDD Self-Coherence
- **CDD alpha:** 3/4 — Design doc exists (GO-KERNEL-COMMANDS.md), CDD trace in PR body, tests present. No separate SELF-COHERENCE.md for this branch (not governance class, so not required). Tag push blocked — artifact incomplete.
- **CDD beta:** 4/4 — Design doc, PR body, code, CHANGELOG, and assessment agree. No authority conflicts. Architecture check passed all 7 questions.
- **CDD gamma:** 3/4 — 1 review round (within target). 0 superseded PRs. Mechanical ratio at 25% (slightly above threshold but single-sample). All immediate outputs executed. Tag push is the gap.
- **Weakest axis:** alpha (tag push blocked — environmental, not actionable as skill patch)
- **Action:** none — the tag push failure is environmental (sandbox 403 on refs/tags/), not a CDD process gap. When the environment supports tag pushes, complete the tag.

### 5. Production Verification

**Scenario:** `cn daily` dispatches to the installed cnos.core package command.
**Before this release:** `cn daily` → "unknown command" (only 8 kernel commands visible).
**After this release:** `cn daily` → executes `cnos.core/commands/daily/cn-daily` via `ExecCommand.Run()`.
**How to verify:** `cn build && cn deps restore && cn daily` in a hub with cnos.core installed.
**Result:** Verified via automated test round-trip (`go test ./...` all 11 packages pass). Full end-to-end verified by PR author during development. Deployment verification deferred — no running agent in this environment.

### 6. CDD Closeout

| Step | Artifact | Skills loaded | Decision |
|------|----------|--------------|----------|
| 11 Observe | PR #231 merged, CI green, release commit on main | post-release | 5 ACs met, architecture preserved |
| 12 Assess | POST-RELEASE-ASSESSMENT.md | post-release | assessment completed — no skill patches needed |
| 13 Close | #226 closed, #228 commented (Step 3 complete) | post-release | cycle closed, deferred: tag push |

### 6a. Invariants Check

| Constraint | Touched? | Status |
|---|---|---|
| INV-001 One package substrate | No | preserved |
| INV-003 Commands/providers/orchestrators/skills distinct | Yes | preserved — commands dispatch only |
| INV-004 Kernel owns policy | Yes | preserved — precedence enforced by kernel registry |
| T-001 Kernel is package-compatible | No | preserved |
| T-002 Kernel remains minimal | Yes | preserved — cmd_*.go thin wrappers, CI-enforced |
| T-004 Source/artifact/installed explicit | Yes | preserved — discovery reads installed state |

### 7. Next Move
**Next MCA:** #192 AC4 — Runtime contract surfaces installed packages and command registry (MVA Step 4)
**Owner:** sigma (next session)
**Branch:** pending creation
**First AC:** `cn status` shows installed packages from vendor
**MCI frozen until shipped?** Yes
**Rationale:** 6 design issues at growing lag. MVA pipeline completion (#228 Steps 3-4) is the priority. No new design docs until growing-lag count drops below 3.

**Closure evidence (CDD section 10):**
- Immediate outputs executed: yes
  - Review posted (PR #231 comment review — shared identity)
  - Findings fixed on-branch (da1bf0e)
  - PR merged (f53dfff squash)
  - Release commit pushed to main (b9a42a7)
  - CHANGELOG updated
  - RELEASE.md written
  - #226 closed
  - #228 commented (Step 3 complete)
- Deferred outputs committed: yes
  - Tag 3.52.0 push — blocked by sandbox 403 on refs/tags/. Tag exists locally. Complete when environment permits.

**Immediate fixes** (executed in this session):
- None needed — all review findings were fixed on-branch before merge.
