# γ close-out — cycle/413

**Cycle:** cnos#413 — Activate Sigma; case (d.2) cross-repo bundle for cn-sigma.
**Role:** γ (with α and β collapsed onto δ for this skill/docs-class cycle).
**Verdict:** Cycle closeable. β R1 APPROVED; all AC1–AC9 PASS; no findings.

## Bundle complete and reviewed

Bundle at `cnos:.cdd/iterations/cross-repo/cn-sigma/sigma-activation-2026-05-22/`:

- `LINEAGE.md` (case (d.2); Disposition `drafted (operator-pending)`)
- `PERSONA-additions.patch` (6 engineering-persona protocol commitments)
- `OPERATOR-additions.patch` (3 CDD wave-execution sub-rules)
- `PERSONA-discipline-receipt-additions.patch` (anti-gaming guardrails)
- `docs/empirical-anchor-cnos-bootstrap-arc.md` (10 rules with cycle citations)

α self-coherence: PASS (per `self-coherence.md`).
β R1: APPROVED (per `beta-review.md`).

## What γ ships

γ commits per role (`α-413:` for bundle authoring, `β-413:` for R1, `γ-413:` for close-outs); pushes `cycle/413` to `origin/cycle/413`; reports to operator.

γ does NOT merge to main — that's the operator's call per dispatch contract. Per case (d.2) lifecycle, the bundle remains `drafted (operator-pending)` until the operator applies the patches to cn-sigma; cnos-side cycle close is independent of cn-sigma application timing.

## Operator-facing apply commands

```
cd usurobor/cn-sigma

# Apply in D2 → D4 → D3 order. D2 and D4 both anchor on `## Continuity rule`
# in PERSONA.md; D2 first ensures correct stacking. D3 is independent of
# PERSONA-side patches. All three use --recount because hunk-header line
# numbers are placeholders (cnos session does not know cn-sigma's exact
# line counts); --recount regenerates line numbers from context-match.

git apply --recount /path/to/cnos/.cdd/iterations/cross-repo/cn-sigma/sigma-activation-2026-05-22/PERSONA-additions.patch
git apply --recount /path/to/cnos/.cdd/iterations/cross-repo/cn-sigma/sigma-activation-2026-05-22/PERSONA-discipline-receipt-additions.patch
git apply --recount /path/to/cnos/.cdd/iterations/cross-repo/cn-sigma/sigma-activation-2026-05-22/OPERATOR-additions.patch

git add spec/PERSONA.md spec/OPERATOR.md
git commit -m "persona+operator: Sigma activation (cnos#413; 6 persona + 3 operator + 1 discipline-augmentation)"
git push
```

## Operator merge instruction (cnos side)

When operator decides to merge:

```
git checkout main
git merge --no-ff cycle/413 -m "Merge cycle/413: Sigma activation case (d.2) bundle (Closes #413)."
git push origin main
```

The `Closes #413` keyword on the merge commit autolinks issue closure.

## Hand-off notes

- **Bundle preserved indefinitely on cnos side** per `cross-repo/SKILL.md §2.8.2`-analog reading (case-d bundles aren't formally covered by §2.8.2, but the audit value is equivalent to case-a target-side mirrors). Once the operator confirms application to cn-sigma, the bundle may move to `archived/` per §2.8.1 case-d archival rule; whether cnos retains an archived copy or deletes is a follow-on decision at archival time.
- **No follow-on cnos issue filed.** This cycle is the last sub of the phase per operator directive ("we'll activate sigma once we're done with the phase"; #403 closed at `378a54f0`). After application, Sigma is staged for #404 (handoff extraction; dispatchable) and #405 (CCNF-O + TSC steering; gated on Sub 1 design).
- **No protocol-gap findings to forward.** β recorded three non-blocking observations (anchor doc line count; `@@ EOF @@` precedent improvement; case-d hat-collapse documentation) but none rise to a binding finding. cdd-iteration.md is a courtesy stub (protocol_gap_count = 0).
