# β Close-out — Cycle #350

**Issue:** #350 — cdd(core): define wave primitive — multi-cycle coordination surface  
**Merge commit:** d7e7dfb9bfe4d30a4d9ee53c3f4fecf1b5d607d8  
**Merge timestamp:** 2026-05-12 18:05 UTC  
**β identity:** beta@cdd.cnos  
**Review rounds:** 1 (R1 → APPROVED)

## Review Context

**Cycle characteristics:**
- **Mode:** docs-only, design-and-build
- **Type:** Protocol extension (wave coordination primitive for CDD)
- **Scope:** Single file modification (operator/SKILL.md + cycle artifacts)
- **CI status:** Green throughout review (Build workflow successful)

**Review approach:**
- Full triadic protocol review (contract integrity → issue contract → diff context → architecture check)
- Phase-by-phase incremental documentation per review/SKILL.md
- CI monitoring throughout review process

**α review-readiness signal quality:** Excellent. Clear base/head SHAs, explicit CI status, complete CDD-Trace through step 7, all ACs with line-number evidence.

## Merge Evidence

**Branch state at merge:**
- Head SHA: 84f28adc (includes β review verdict)
- Base SHA: 4e83c66deede57686b85e3a8a41117d212417468

**Integration verification:**
- No merge conflicts encountered
- All cycle artifacts present on main after merge
- Issue #350 auto-closed via merge commit

## Cycle Findings

**Process observations:**

1. **Clean docs-only execution:** The cycle properly followed docs-only mode throughout. No scope creep into runtime implementation. Non-goals clearly observed (no parallel wave execution, no CI/CD integration, no single-cycle structure changes).

2. **Empirical foundation:** Implementation based on actual artifacts from `.cdd/waves/hardening-2026-05-12/` and findings from `.cdd/iterations/wave-2026-05-12.md`. Design grounded in proven patterns, not theoretical constructs.

3. **Protocol extension pattern:** Wave primitive extends CDD cleanly. New `.cdd/waves/` directory parallel to `.cdd/unreleased/`. δ role gains wave dispatch capability while preserving all existing single-cycle authority. No breaking changes to γ/α/β contracts.

4. **Complete format definition:** All 7 ACs implemented with concrete formats. δ dispatch template parallel to existing γ templates. Manifest/status/closure formats with clear examples. Iteration lifecycle connecting wave execution to release process.

5. **Authority surface clarity:** No conflicts detected. Wave coordination lives entirely in operator/SKILL.md. Clear separation between wave-level coordination and single-cycle execution.

**Review quality indicators:**
- Zero blocking findings across all review phases
- Contract integrity sound (all 10 checks passed)
- Complete AC coverage with line-number evidence  
- Architecture check mostly N/A but no violations detected
- CI green at review completion

**β review efficiency:**
- Single-round approval (no REQUEST CHANGES cycles)
- Review completed within CI completion window
- Incremental review artifact construction worked smoothly

## Observations for γ

**Strength patterns:**
- α's self-coherence quality high (complete CDD-Trace, explicit debt examination, clear review-readiness signal)
- Implementation scope well-bounded (docs-only respected throughout)  
- Empirical validation approach (building on actual wave artifacts)

**Process notes:**
- Triadic coordination worked cleanly for this docs-only cycle
- β monitoring of CI status integrated well with review phases
- No γ unblocking required during cycle execution

**Release readiness:**
- This cycle follows docs-only disconnect path (merge commit is disconnect, no tag)
- All required artifacts present and complete
- Implementation ready for immediate use in next wave dispatch
