# γ Close-Out — 3.59.0 (#230, PR #274)

## Cycle summary

- **Cycle:** #230 — *B1: distribution chain honesty — restore version-skip + release-bootstrap smoke* (subsumes #238).
- **Selection:** CDD §3.3 (PRA §7 fallback stack: #268 closed → #230 next) + §3.5 (MCI freeze, stale set). #230 was a P1 growing-lag item from the 3.58.0 PRA encoding-lag table, named explicitly in 3.58.0 PRA §7's candidate stack as "#230 (`cn deps restore` version-upgrade skip — P1, one-function fix, complementary to the dist-out-of-git L7 MCA)."
- **Dispatch:** γ → α + β simultaneously per the dispatch-model patch landed in 3.58.0 PRA. Issue-quality gate (γ/SKILL.md §2.4) held cleanly — #230's body had all 11 fields present at dispatch time; no compensation in the prompt; α and β began intake in parallel.
- **Outcome:** L7 diff / L6 cycle cap. Three failure classes turned into mechanical fail-fasts: silent v1→v2 vendor skip (`restore.restoreOne` reinstall on drift); runtime can't see authority disagreement (`doctor.checkPackages` stale-list with named diagnostics); released binary cannot self-bootstrap (`release-smoke.yml` 4-platform matrix on every published release + `release.yml` ldflags-stamping pinning binary version to tag).
- **Score:** C_Σ A- (α A-, β A, γ A-, level L6 cycle cap; diff L7) — confirms β's CHANGELOG provisional score without revision.
- **Cycle shape:** 2 review rounds (target ≤2 met); 4 R1 findings (F1 C, F2 B, F3 B, F4 A) all closed in one R2 commit; 0 R2 findings; CI 7/7 green at every reviewed head.
- **Artifacts:**
  - PR #274 (`9980e3f`) → release commit `9dd30d9d` (β) → α close-out `be81280a` → β close-out addendum `6f2c218e` (tag-deferral) → this γ close-out + PRA at `docs/gamma/cdd/3.59.0/POST-RELEASE-ASSESSMENT.md`.
  - Release `3.59.0` published 2026-04-26T11:20:37Z with 12-asset matrix (4 binaries, 5 package tarballs, index.json, checksums.txt) — operator pushed the tag after β's HTTP 403 deferral.

## Close-out triage table (CAP)

| Finding | Source | Type | Disposition | Artifact / commit |
|---------|--------|------|-------------|-------------------|
| F1: doctor.checkPackages parses cn.package.json inline; should reuse pkg.ParseInstalledManifestData (C judgment, loaded-skill miss on eng/go §2.17 generalization) | β #274 R1 / α close-out / γ PRA §3 | skill | **Immediate MCA** — patch eng/go §2.17 with diff-local canonical generalization rule. Lands in this PRA commit. | `src/packages/cnos.eng/skills/eng/go/SKILL.md §2.17` |
| Polling-discipline gap (transition-only Monitor first-iteration absorption silently masks pre-existing state) | α close-out §What didn't 5 + β close-out §β polling pattern + γ this PRA §3 (three sessions, one cycle) | skill | **Immediate MCA** — patch cdd/CDD.md §Tracking with synchronous-baseline-pull precondition rule. Lands in this PRA commit. | `src/packages/cnos.cdd/skills/cdd/CDD.md §Tracking` |
| Branch-glob narrowness (CDD §Tracking template assumes harness encodes issue number; harness used in this cycle does not) | β close-out §Branch-glob narrowness + γ this PRA §3 | skill | **Immediate MCA** — patch cdd/CDD.md §Tracking with broader-glob-with-downstream-filtering rule. Lands in this PRA commit alongside the synchronous-baseline patch (one § block, two related edits). | `src/packages/cnos.cdd/skills/cdd/CDD.md §Tracking` |
| Polyglot pre-review-gate row 9 was Go-only (3 of 4 R1 findings landed in surfaces α's Go-shaped re-audit didn't exercise) | α close-out §What didn't 4 + α §Cycle Iteration root cause + γ PRA §3 | skill | **Immediate MCA** — patch cdd/alpha §2.6 row 9 with polyglot re-audit rule. Lands in this PRA commit. | `src/packages/cnos.cdd/skills/cdd/alpha/SKILL.md §2.6` |
| F2: smoke header lied about checksums.txt authority (B judgment, header-as-contract drift) | β #274 R1 / α close-out F2 root cause | drop (one-off) | Application-side draft-then-revise leftover; α fixed cleanly in R2; pattern is below noise floor for skill patching. No patch. | — |
| F3: missing test for `(unparseable manifest)` doctor branch (B judgment, test-planning by AC narrative under-covered diagnostic-string family) | β #274 R1 / α close-out F3 root cause | drop (application gap) | `eng/test §3.6` + §3.13 already cover "every meaningful boundary gets a test" / "cover new surfaces." α's application gap, not skill underspecification. No patch. | — |
| F4: smoke `BIN_VERSION_OUT` dead capture (A mechanical, draft-simplification leftover) | β #274 R1 | drop (one-off mechanical) | Caught cleanly by review §2.1 mechanical scan; below skill-patch threshold. No patch. | — |
| Tag-push HTTP 403 from sandbox-bound sessions (5+ consecutive cycles) | β close-out §Tag-push deferral + γ this PRA §3 + 3.58.0 PRA §7 | agent MCI / operator-deferred | **Carry-forward MCI** — drafted in 3.58.0 PRA §7 deferred outputs; standing on GitHub MCP auth refresh. Operator path worked this cycle (tag pushed within 16 minutes; release matrix fired automatically). Not a skill-side patch. | 3.58.0 PRA §7; this PRA §3 + §7 |
| Branch-name harness drift vs CDD §4.2 (`claude/alpha-tier-3-skills-IZOsO` non-canonical for issue #230) | β close-out §Harness branch-naming drift + α close-out §Cycle context + γ PRA §3 | agent MCI / operator-deferred | **Carry-forward MCI** — drafted in 3.58.0 PRA §7; γ-side mitigation is to pin canonical branch name in dispatch prompt. Carry forward to next cycle's dispatch. | 3.58.0 PRA §7; this PRA §7 |
| Pre-existing stale doc-paths in eng/go §2.17/§2.18 (→ INVARIANTS.md) and pkg.go:134 (→ POLYGLOT-PACKAGES-AND-PROVIDERS.md) | β close-out Notes (non-findings) + α close-out (mentioned in close-out) | drop (defer-to-next-touch) | Pre-existing on main; out of #230 scope; the next cycle that edits §2.17 or pkg.go can include the path-string repair as a small-change-path immediate output per CDD §5.6 frozen-snapshot rule's path-reference-repair allowance. RELEASE.md also names this as a known issue. | — |
| #266 AC3 recurrence-tracking commitment (rebase-race class) | 3.58.0 PRA §7 | observational | This cycle was `src/go/`-touching, not `src/packages/`-touching; no race observed. Observation N=2 cycles clean since L7 MCA shipped. Continue tracking. | — |

**Silence is not triage.** Every finding gets a disposition; this table covers all 4 R1 findings + 3 process observations + 4 standing carry-forwards. No "noted, will revisit later" residue.

## §9.1 trigger assessment

| Trigger | Fired? | Disposition |
|---|---|---|
| review rounds > 2 | no — actual: 2 (at threshold, not above) | n/a |
| mechanical ratio > 20% with N ≥ 10 | partial — 25% but N=4 ≪ 10-floor | recorded; no automatic trigger fire |
| avoidable tooling/env failure | **yes** — HTTP 403 on tag-ref writes from sandbox (5 consecutive cycles) | deferred-to-operator standing MCI from 3.58.0 PRA §7; not a skill-side patch; operator path worked this cycle |
| **loaded skill failed to prevent a finding** | **yes** — eng/go §2.17 was loaded but did not prevent the diff-local parallel-parser introduction (F1); CDD §Tracking was loaded but did not prevent the polling-discipline gap that hit α + β + γ in three independent sessions | **patches land in this PRA commit** — eng/go §2.17 (diff-local generalization), cdd/CDD.md §Tracking (synchronous-baseline + glob-template), cdd/alpha §2.6 row 9 (polyglot re-audit) |

Closure rule: every fired §9.1 trigger has either a landed patch (loaded-skill miss → 3 patches landed; cycle iteration § in PRA) or a deferred-to-operator MCI (env-failure → 5-cycle standing MCI). Closure gate met.

## Cycle iteration

The cycle exhibited the L6 cycle-cap miss in the form of one F1 cross-surface parser duplication reaching review (cf. PRA §4b for full root-cause analysis). The fix shape — "add the smaller-scale application as an explicit case in the skill text, derive-from-cycle, keep the existing exemplar" — was applied consistently across all four patches in this commit. Cycle level **L6 (cycle cap), L7 (diff)** confirmed without revision.

## Skill gap candidate dispositions

(Repeated from PRA §3 active skill re-evaluation for close-out completeness.)

- `eng/go/SKILL.md §2.17` Purity boundary — **underspecified, patched.**
- `cdd/CDD.md §Tracking` — **underspecified, patched** (two related edits: synchronous-baseline + glob-template).
- `cdd/alpha/SKILL.md §2.6` row 9 — **underspecified, patched.**
- `eng/test/SKILL.md §3.6 / §3.13` — **already covered.** Application gap; no patch.
- `cdd/review/SKILL.md §2.2.8 / §3.3` — **worked as written.** No patch.
- `cdd/gamma/SKILL.md §2.4` — **worked as written.** No patch.
- `cdd/post-release/SKILL.md` ownership — **continues to hold cleanly.** No patch.
- `eng/tool/SKILL.md` smoke template — **worked as written.** No patch.

## Deferred outputs

- **#235** (`cn build --check`) — next MCA; α to dispatch on next cycle (per PRA §7 + §2 lag-table prioritization).
- **#262 deferred ACs** (AC1 `cn pack` rename, AC5 `--list`/`--dry-run`, AC3 root-file narrowing, B1 root-file content-class migration prerequisite) — carry forward; ranked after #235.
- **#218** (cnos.transport.git design) — P1 growing; ranked after #262 AC1/AC5.
- **Stale-backlog re-evaluation per §3.4** — older #190/189/186/etc. set, 3+ cycles deferred; needs descope/consolidate/commit triage cycle.
- **Pre-existing stale doc-paths** (eng/go §2.17/§2.18 and pkg.go:134 references) — defer-to-next-touch.
- **Branch-name validation MCI** — deferred-to-operator on auth refresh (from 3.58.0 PRA §7).
- **Harness ref-write 403 MCI** — deferred-to-operator on auth refresh (from 3.58.0 PRA §7); 5-cycle pattern reconfirmed.
- **#266 AC3 recurrence-tracking** — observational; N=2 cycles clean since L7 MCA; continue tracking.
- **`release-smoke.yml` first-run observation** — fires on `release: published` for 3.59.0; pass-path result will be visible post-PRA-commit; record on next adjacent cycle's PRA-style observation.
- **Branch cleanup** — γ session branch (`claude/gamma-skill-issue-230-0aiRa`) and PR #274's branch (`claude/alpha-tier-3-skills-IZOsO`) and any prior cycles' still-merged remotes — deferred-to-operator on the standing harness-403 MCI.

## Hub memory evidence

- **Daily reflection analog:** `docs/gamma/cdd/3.59.0/POST-RELEASE-ASSESSMENT.md` (this PRA commit).
- **Adhoc thread analogs in `.cdd/releases/3.59.0/`:**
  - `alpha/CLOSE-OUT.md` — distribution-chain-honesty implementation thread
  - `beta/CLOSE-OUT.md` — review-discipline thread
  - `gamma/CLOSE-OUT.md` (this file) — γ orchestration thread
- **Ongoing thread advances:**
  - *Authority clarity thread:* 3.57.0 (filesystem-as-authority for skills) → 3.58.0 (checksum-manifest-as-authority for tarballs) → 3.59.0 (installed `cn.package.json` + shared parser as authority for installed-version, with `slog`-attr ↔ doctor-diagnostic vocabulary unification). Next adjacent move: #235 `cn build --check` (manifest-as-authority for declared entrypoints + skill paths).
  - *CDD method polling-discipline thread:* 3.58.0 shipped 15 agent-compliance patches; 3.59.0 lands 4 step-12a patches addressing the residual gaps from three independent role sessions one cycle (synchronous-baseline-pull + broader claude/* glob + diff-local canonical generalization + polyglot re-audit).
- **External hub-memory sync:** operator action when `cn-sigma` agent surface resumes; in-repo content (this file + PRA) is durable.

## Next MCA

- **Issue:** #235 — `cn build --check` validates entrypoints + skill paths against manifest.
- **Owner:** α (next dispatch).
- **Branch:** canonical form per CDD §4.2 = `<agent>/235-cn-build-check`. **γ should pin this canonical name in the next dispatch prompt** until the branch-name validation MCI from 3.58.0 PRA §7 lands (the new CDD §Tracking patch gives the polling fallback when harness diverges; pinning the branch name in the prompt is the upstream fix).
- **First AC:** the smallest manifest↔filesystem contradiction `cn build --check` should fail-fast on — a `cn.package.v1` manifest declaring an entrypoint that does not exist on disk.
- **MCI frozen until shipped?** Yes — 8 growing-lag items, freeze continues.

## Cycle status

**Cycle #230 closed.** Next: **#235**.
