# α self-coherence — Cycle 419

**Issue:** [cnos#419](https://github.com/usurobor/cnos/issues/419) — Sub 5 of [cnos#404](https://github.com/usurobor/cnos/issues/404)
**Branch:** `cycle/419` from `origin/main @ 1bf9f92f`
**Mode:** docs-only / package migration; γ+α+β collapsed on δ
**Date:** 2026-05-22

## Gap and mode

The cycle extracts cdd-iteration receipt-stream + INDEX.md aggregator doctrine from `cnos.cdd/skills/cdd/post-release/SKILL.md §5.6b` into a new canonical home at `cnos.handoff/skills/handoff/receipt-stream/SKILL.md` (Sub 5 of the cnos#404 wave). Same three-ruling pattern as Subs 2 / 3 / 4 (cnos#416 / cnos#417 / cnos#418): wholesale move; source becomes pointer; consumer cross-references updated. Per-finding shape (six top-level fields + per-disposition sub-fields), INDEX.md row format (eight pipe-separated columns), cadence rule (required when `protocol_gap_count > 0`; courtesy stub when 0 per cycle/401), and finding-disposition vocabulary (`patch-landed` / `next-MCA` / `no-patch`) are preserved verbatim.

## ACs (cnos#419)

| AC | Description | Result |
|---|---|---|
| AC1 | `test -f src/packages/cnos.handoff/skills/handoff/receipt-stream/SKILL.md` + post-release/SKILL.md exists with §5.6b replaced | **PASS** — both files exist; §5.6b is a 6-line pointer |
| AC2 | ≥ 6 receipt-stream keyword hits; 200 ≤ lines ≤ 500 | **PASS** — 88 keyword hits; 340 lines |
| AC3 | §5.6b ≤ 30 lines; post-release/SKILL.md ≥ 80% original; ≥ 1 cite of new canonical | **PASS** — §5.6b = 6 lines; 444/488 = 91% of original; 2 cites of new canonical path |
| AC4 | HANDOFF.md receipt-stream under Landed; all 5 sub-skills landed | **PASS** — 3 receipt-stream mentions in HANDOFF.md; all 5 sub-skills under "### Landed (v0.1)" |
| AC5 | extraction-map.md §6 rows marked migrated | **PASS** — 5 "v0.1 migrated.*receipt-stream" hits in extraction-map.md |
| AC6 | handoff/artifact-channel cites receipt-stream | **PASS** — 6 receipt-stream cite hits in artifact-channel/SKILL.md; all "forthcoming" qualifiers dropped |
| AC7 | cnos.cdr untouched | **PASS** — `git diff origin/main..HEAD -- src/packages/cnos.cdr/` returns 0 lines |
| AC8 | INDEX.md content unchanged | **PASS** — `git diff origin/main..HEAD -- .cdd/iterations/INDEX.md` returns 0 lines (cycle's own close-out row added in β commit) |
| AC9 | no schemas/handoff, no schemas/ccnf-o, no cdd-verify / src/go / release.sh changes | **PASS** — schemas/handoff/ absent; schemas/ccnf-o/ absent; runtime diff = 0 lines |
| AC10 | CDD.md kernel byte-identical (≤ 5 lines insertion) | **PASS** — 0 lines diff against origin/main |
| AC11 | spot-check verbatim preservation | **PASS** — per-finding shape diffs verbatim against source; INDEX row format `| Cycle | Issue | Date | Findings | Patches | MCAs | No-patch | Path |` preserved; cadence rule verbatim; disposition vocabulary `patch-landed` / `next-MCA` / `no-patch` preserved |

## Trace

The receipt-stream sub-skill's content was extracted from `cnos.cdd/skills/cdd/post-release/SKILL.md §5.6b` (pre-edit lines 293–340; 48 lines of canonical content) and re-cohered into a sub-skill (`receipt-stream/SKILL.md`, 340 lines) with the standard structure (Core principle / Authority / Scope / §1 Per-finding shape / §2 Aggregator / §3 Cadence rules / §4 Aggregator location / §5 Finding-disposition discipline / §6 Cross-repo trace / §7 Empirical anchors / §8 Related documents / §9 Non-goals / §10 Kata) matching the Sub 4 artifact-channel/SKILL.md precedent.

Per-finding fields (six top-level + per-disposition sub-fields), INDEX row format (eight pipe-separated columns), cadence rule (`protocol_gap_count > 0` required; courtesy stub when 0 per cycle/401), and disposition vocabulary are preserved verbatim (see AC11 spot-check above). The empirical anchors section names cycle/335 (INDEX bootstrap) and cycle/401 (courtesy stub convention) explicitly per cnos#419 D1.

post-release/SKILL.md §5.6b is now a 6-line pointer paragraph; the §-anchor is preserved for backward-compatible citation. Other sections of post-release/SKILL.md are unchanged (file dropped from 488 → 444 lines = 91% of original; the only delta is the §5.6b content rewrite).

Consumer cross-references repaired:
- handoff/artifact-channel/SKILL.md — dropped "forthcoming" qualifiers on 4 receipt-stream cites (§Scope, §1.2, §2.5, §6 "Related documents", §7 "Non-goals")
- handoff/cross-repo/SKILL.md — repointed 2 cites of `post-release/SKILL.md §5.6b` to handoff/receipt-stream/SKILL.md (bundle-file-set table; §5 "Cross-references")
- handoff/SKILL.md — loader updated (drop "until Sub 5 lands" qualifier; manifest entry now cites cnos#419; "Until Subs 2–5 land" v0.1 caveat updated to cite handoff/receipt-stream as the new canonical)
- handoff/README.md — Sub 5 entry now marked landed under cnos#419
- handoff/HANDOFF.md — receipt-stream added under "### Landed (v0.1)"; all 5 sub-skills now landed; non-goals row updated to include per-finding shape / INDEX row format / cadence rule / disposition vocabulary
- 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
- cnos.cdd/skills/cdd/epsilon/SKILL.md §1 — 3 cites of `post-release/SKILL.md §5.6b` repointed to handoff/receipt-stream/SKILL.md (per-finding shape; cadence rule; aggregator); §3 "Cross-references" now lists handoff/receipt-stream/SKILL.md as canonical + post-release as pointer
- cnos.cdd/skills/cdd/activation/SKILL.md §22 — 2 cites of `post-release/SKILL.md §5.6b` repointed to handoff/receipt-stream/SKILL.md (cadence-rule rationale + per-finding shape reference)

cnos.cdr untouched (0-line diff). CDD.md kernel untouched (0-line diff). schemas/handoff/ absent; schemas/ccnf-o/ absent; cdd-verify / src/go / release.sh untouched.

## Review-readiness | round 1

α has authored all D1–D5 deliverables. AC1–AC11 PASS per the matrix above. Verbatim preservation spot-checks for per-finding shape, INDEX row format, cadence rule, and disposition vocabulary all match the source.

The cycle is ready for β review.
