# α close-out — Cycle 419

**Cycle:** [cnos#419](https://github.com/usurobor/cnos/issues/419) — Sub 5 of [cnos#404](https://github.com/usurobor/cnos/issues/404)
**Date:** 2026-05-22

## Outputs

- **D1:** `src/packages/cnos.handoff/skills/handoff/receipt-stream/SKILL.md` authored (340 lines; 10 substantive sections; 88 keyword hits).
- **D2:** `src/packages/cnos.cdd/skills/cdd/post-release/SKILL.md §5.6b` rewritten as pointer (6 lines; preserves §-anchor; cites new canonical home). post-release/SKILL.md dropped from 488 → 444 lines (91% of original).
- **D3:** `src/packages/cnos.handoff/skills/handoff/HANDOFF.md` updated: receipt-stream under "### Landed (v0.1)"; all 5 sub-skills now landed; non-goals row extended.
- **D4:** `src/packages/cnos.handoff/docs/extraction-map.md §6` rows marked `Status: v0.1 migrated; canonical at cnos.handoff/skills/handoff/receipt-stream/SKILL.md` with destination-§ specificity.
- **D5:** Cross-references repaired in handoff/artifact-channel/SKILL.md (4 forthcoming-qualifier drops), handoff/cross-repo/SKILL.md (2 cite repoints), handoff/SKILL.md loader (caveat + manifest), handoff/README.md (Sub 5 landed), cnos.cdd/skills/cdd/epsilon/SKILL.md §1 + §3 (3 cite repoints), cnos.cdd/skills/cdd/activation/SKILL.md §22 (2 cite repoints).

## Findings

α surfaces three observations during authoring; none rise to `cdd-*-gap` class.

### F1: extraction-map.md §6 row 5 ("INDEX.md aggregator file itself") is a content-vs-doctrine distinction

**Observation.** The §6 row for `.cdd/iterations/INDEX.md` was marked "Status: content unchanged" rather than "v0.1 migrated" because the file is data, not doctrine; the doctrine about it (how to update it, row format) migrated, but the content rows stayed at the existing path. This was the right call (per the cnos#419 issue body and extraction-map.md §6 row 5 pre-existing note); the marking convention "content unchanged" is novel for this row and may be useful precedent for future data-vs-doctrine boundary rows.

**Disposition.** No-patch. Observation only; the marking is self-explanatory in the row's note column.

### F2: handoff/cross-repo/SKILL.md §2.5 case-(c) row preserved the `cnos.cdd/skills/cdd/epsilon/SKILL.md §1` cite

**Observation.** The bundle-file-set row for case (c) bilateral iteration previously cited both `cnos.cdd/skills/cdd/post-release/SKILL.md §5.6b` and `cnos.cdd/skills/cdd/epsilon/SKILL.md §1`. The post-release cite was repointed to handoff/receipt-stream/SKILL.md; the epsilon cite was preserved (epsilon is the role-local authority on the CDD-side gap-class vocabulary; this skill is the wire-format canonical). The dual-cite is correct per the Authority section of receipt-stream/SKILL.md.

**Disposition.** No-patch. The dual-cite is structurally correct.

### F3: post-release/SKILL.md §5.6b dropping (from 48 lines to 6 lines) is the largest single-section delta in the Sub 2–5 wave

**Observation.** Sub 5's §5.6b pointer rewrite (48 → 6 lines net) is the largest single-section delta among the four migration subs. Sub 2 (cnos#416) replaced the entire 644-line cross-repo/SKILL.md with a ~28-line compatibility pointer; Sub 3 (cnos#417) made multiple smaller §-edits across three role skills; Sub 4 (cnos#418) added 2 new files + small two-line CDS pointer edits. Sub 5's source section was the most cohesive single section in the wave, so the migration is the cleanest single-section move.

**Disposition.** No-patch. Observation; pattern noted for the cnos#404 wave retrospective Sub 6 may run.

## Trace

All 10 modified files + 1 new file pass AC1–AC11 per self-coherence.md. cnos.cdr untouched. CDD.md kernel byte-identical. schemas/handoff/ absent. INDEX.md content unchanged (only this cycle's close-out row added in β commit).

The cycle's intent — Sub 5 of cnos#404; extract cdd-iteration receipt-stream + INDEX.md aggregator doctrine into cnos.handoff — is delivered. After β approves and merges, all 5 handoff sub-skills are Landed. Sub 6 handles final cross-reference cleanup + closes the cnos#404 tracker.
