# γ close-out — cycle/301-mci

## Cycle summary

| | |
|---|---|
| Cycle | `301-mci` — small-change direct cycle (no GitHub issue). Re-lands 3 deferred MCIs from #301 γ-closeout (deferred outputs 1, 2, 4). |
| Branch | `cycle/301-mci` from `origin/main` at `00df92d1` (the revert of the prior failed landing). |
| Merge | `5b65cee9` — no-ff merge to main. |
| Mode | Identity-rotation. γ owns full cycle (implement + self-review as β). |
| Patches | 3 Markdown-only skill file edits. No tests required (doc-only). |
| Review | γ self-review as β. APPROVED. No findings. |
| Prior attempt | `967d7f7b` (authored `beta@cdd.cnos`, landed outside cycle process) was reverted at `00df92d1`. This cycle re-lands identical content through the correct cycle branch + merge path. |

## Close-out triage

| # | Deferred output (from 301g) | AC | Disposition |
|---|---|---|---|
| 1 | `alpha/SKILL.md` § readiness-signal section: SHA convention rule | Two stable patterns (implementation SHA; omit SHA + polling); one anti-pattern (HEAD-at-write-time recursive self-stale); ❌/✅ examples. | **Landed** — `a4aedf56`. §2.6 of `alpha/SKILL.md` now carries the "SHA convention for readiness signal" block immediately before "Transient vs durable rows". |
| 2 | `gamma/SKILL.md` § after dispatch rules: "Spec-staleness propagation" subsection | Identity-rotation mode: not applicable. Long-lived sessions: write `gamma-coordination.md` to `origin/cycle/{N}`. When to / not to propagate defined. | **Landed** — `a4aedf56`. Subsection inserted between Step 3b dispatch rules and Step 5 — Unblock in `gamma/SKILL.md §2.5`. |
| 4 | `issue/SKILL.md` rule 3.14 + handoff checklist item | α must surface contradictions to γ before implementing. Rule + checklist item present. | **Landed** — `a4aedf56`. Rule 3.14 appended after 3.13; checklist item added after "Scope and non-goals do not contradict ACs." |

Deferred output 3 (cn dispatch CLI) was superseded by #310 and is out of scope here.
Deferred outputs 5a–c (CTB spec: cross-package calls, name grammar, α polling post-release path) remain deferred to CTB-spec-touching cycle.

## Findings

None. No β findings; γ self-review clean.

## §9.1 triggers

No triggers fired. This is a single-commit doc-only small-change cycle; review churn, mechanical overload, tooling failure, and loaded-skill miss conditions do not apply.

## Skill / spec patch scope

All three patches are in the CDD skill package (`src/packages/cnos.cdd/skills/cdd/`). Peer enumeration:
- `alpha/SKILL.md` — primary patch target. No lifecycle-skill dependents consume the SHA convention rule directly; the rule is α-authoring guidance.
- `gamma/SKILL.md` — primary patch target. Spec-staleness propagation subsection is γ-coordination guidance; no downstream lifecycle-skill encoding of the rule exists yet.
- `issue/SKILL.md` — primary patch target. Rule 3.14 and checklist item are γ/α-facing guidance. `design/SKILL.md` and `plan/SKILL.md` do not encode contradiction-resolution rules; no sibling update needed.

No harness, schema, or CI changes.

## Closure

This cycle's deferred outputs 1, 2, 4 from #301 are fully landed. The re-land is clean and cycle process is restored after the prior revert.
