## Implementation Summary

Six CDD protocol gap patches authored and merged via PR #332 (`315e5292`), branched from `cycle/331-cdd-supercycle-learnings`.

| Patch | Commit | Surface patched | Finding class |
|---|---|---|---|
| P1 | `1a4f1966` | `cdd/review/SKILL.md` §3.13 | cdd-protocol-gap |
| P2 | `68c18d23` | `cdd/issue/SKILL.md` mode + MCA preconditions | cdd-protocol-gap |
| P3 | `10f71e7f` | `cdd/release/SKILL.md` §2.5b | cdd-protocol-gap |
| P4 | `878caf62` | `CDD.md` review metrics + CHANGELOG Rounds column | cdd-metric-gap |
| P5 | `b27fc15b` | `cdd/release/SKILL.md` §3.8 | cdd-skill-gap |
| P6 | `d3c3b3ca` | `cdd/post-release/SKILL.md` Step 5.6b + INDEX.md schema | cdd-protocol-gap |

## Drift Items at Close-Out

All six patches land correctly on `cnos:main`. The following close-out artifacts were NOT produced at cycle time:

- `self-coherence.md` — missing
- `beta-review.md` — missing
- `alpha-closeout.md` — missing (this file)
- `beta-closeout.md` — missing
- `gamma-closeout.md` — missing
- `cdd-iteration.md` — missing (the very artifact cycle #331 introduced)

Recursive irony: cycle #331 patch 6 required `cdd-iteration.md` for cycles with `cdd-*-gap` findings; cycle #331 itself had 6 such findings and produced no such file.

## α Grade (self-assessed, retroactive)

**α: B** — Patches are technically correct and verbatim from the cross-repo supercycle proposals. No review-driven changes needed (confirmed by retroactive inspection). However, the entire close-out artifact set was skipped, including `self-coherence.md` which is the α's primary obligation. Skipping self-coherence while introducing a new protocol requiring it is the central α-axis failure of this cycle.

Per §3.8 rubric: B = "met core ACs; partial-protocol release."
