# β Close-out — Cycle #348

## Review Context

**Issue:** #348 — ROLES.md §4: hats-vs-actors principle  
**Mode:** docs-only, design-and-build  
**Review rounds:** 2 (R1 REQUEST CHANGES → R2 APPROVED)  
**Implementation SHA:** 712705b0  
**Merge SHA:** 214b3617

## Narrowing Pattern

**R1 → R2 convergence:** Single mechanical finding in R1 (file edits not executed) resolved completely in fix round. No design iteration required — α's specification was complete and correct from R1.

**Finding pattern:** B-severity mechanical finding (file execution gap). This represents workflow constraint, not design gap. The implementation content was fully specified and ready for execution in R1.

**Review-readiness signal effectiveness:** α's review-readiness signals were accurate. The "pending file edits" constraint was clearly declared in self-coherence.md.

## Merge Evidence

**Merge commit:** 214b3617 (`Merge cycle/348: ROLES.md §4 hats-vs-actors principle`)  
**Merge strategy:** `--no-ff` (preserves branch history per CDD convention)  
**Branch state before merge:** cycle/348 at 5727fa38  
**Main state before merge:** 5a9055a1  
**CI state at merge:** green (all Build workflows succeeded)

**Files modified:**
- `ROLES.md` — Added §4 "Hats vs actors: roles as behavioral contracts" with principle, independence reasoning, three worked examples
- `src/packages/cnos.cdd/skills/cdd/operator/SKILL.md` — Added cross-reference to ROLES.md §4 in §5.2  
- `src/packages/cnos.cdd/skills/cdd/epsilon/SKILL.md` — Added cross-reference to ROLES.md §4
- `.cdd/unreleased/348/self-coherence.md` — α primary artifact with complete implementation specification
- `.cdd/unreleased/348/beta-review.md` — β review record (R1 REQUEST CHANGES, R2 APPROVED)

**Issue closure:** #348 automatically closed via `Closes #348` in merge commit message

## β-side Findings

**Process observations:**
1. **Specification-first approach effective** — α's complete specification in self-coherence.md §CDD-Trace step 6 enabled efficient fix execution without design iteration
2. **Permission constraint handling** — Workflow issue (file write permissions) was clearly declared as constraint rather than hidden, enabling targeted resolution
3. **Cross-reference consistency** — All cross-references correctly target the new §4 and use consistent language

**Quality observations:**
1. **Content quality high** — The hats-vs-actors principle is well-reasoned with clear structural logic
2. **Worked examples effective** — Three examples (δ=γ, α=β, ε=δ) provide clear precedent for future collapse decisions  
3. **Integration clean** — New content integrates smoothly with existing ROLES.md structure

**No skill gaps identified.** Standard docs-only cycle with straightforward implementation.

## Release Evidence (docs-only disconnect)

**Disconnect type:** docs-only (no version bump per release/SKILL.md §2.5b)  
**Disconnect signal:** Merge commit 214b3617 on main  
**No tag required:** This is documentation/protocol change, not code release  
**No CHANGELOG ledger row:** Docs-only cycles do not update Release Coherence Ledger  

**PRA responsibility:** γ will write `docs/gamma/cdd/docs/2026-05-12/POST-RELEASE-ASSESSMENT.md` per docs-only flow

**Artifact movement ready:** `.cdd/unreleased/348/` ready for move to `.cdd/releases/docs/2026-05-12/348/` during γ closure

## No Findings

No β-side cycle findings. Standard docs-only implementation with clear specification, efficient fix execution, and successful integration.
