# γ Closeout — Cycle #389

Actor: gamma@cdd.cnos (δ-as-agent, collapsed-mode)

## §Summary

Phase 3 of cnos#366 lands. V (`cn-cdd-verify --receipt <path>`) is the executable validator predicate. The recursive coherence-cell kernel now has a runtime trust gate; δ (Phase 4) can mechanically consume `ValidationVerdict` JSON.

## §Cycle metabolism

- γ-scaffold: surfaces enumerated, AC oracle approach documented
- α design: L7 design record (`design-notes.md`); implementation choice (hybrid bash + Python); CUE invocation strategy; ValidationVerdict JSON schema; counterfeit-receipt rules
- α build: V implementation + 5 counterfeit fixtures + AC harness
- α self-coherence: AC1–AC8 mapped to oracles + harness output
- β review (collapsed): mechanical re-derivation of every AC; one design-finding surfaced and addressed in-cycle (F0 → `mode: collapsed`); APPROVE

37/37 AC oracle PASS. No RC rounds needed.

## §Post-merge plan

Once merged:

1. **Comment on cnos#366** marking Phase 3 shipped; Phase 4 (δ split) unblocked. Phase 4's input contract is now the JSON Schema at `schemas/cdd/validation_verdict.schema.json` + the V invocation surface (`cn cdd-verify --receipt R --json`).
2. **Update `.cdd/iterations/INDEX.md`** with row for #389 (per closure-gate hygiene; #388 missed this — don't repeat).
3. **Attempt branch deletion** (`git push origin --delete cycle/389`); expect 403 per the harness's known pattern; leave a note here.
4. **No additional release work** — this is an unreleased cycle (per the project's release cadence; `INDEX.md` for the cycle is the iteration index, not a version index).

## §Phase 4 readiness signal

Phase 4 (δ split) is unblocked. Its input contract is:

- `cn cdd-verify --receipt R --json` → `ValidationVerdict` JSON per `schemas/cdd/validation_verdict.schema.json`
- `result: PASS` → δ may record `BoundaryDecision.action ∈ {accept, release}`
- `result: FAIL` + `failed_predicates: [...]` → δ may record `action ∈ {reject, repair_dispatch}`, or `action: override` with the override block populated per §Q4

The δ-as-skill split can be designed against this surface without reading V's implementation.

## §Phase 5 readiness signal (advisory)

Phase 5 (γ shrink) becomes much more feasible after this cycle. γ's job at close-out is now reducible to:

- Author the receipt (frontmatter + 5 evidence refs + protocol_gap signal)
- Invoke V (γ-preflight, non-authoritative)
- Pass to δ for final V invocation + BoundaryDecision

The receipt-authoring discipline can be a small γ-skill; everything else lives in V + δ.

## §Branch cleanup attempt note

After merge, branch deletion attempted; result as expected per harness pattern:

```
$ git push origin --delete cycle/389
error: RPC failed; HTTP 403 curl 22 The requested URL returned error: 403
fatal: the remote end hung up unexpectedly
Everything up-to-date
```

403 is the documented harness pattern (recorded across multiple recent cycles; see wave-2026-05-19 ε iteration F5 for the canonical reference). Branch remains on remote until repo permissions allow delete.
