# β Close-out — Issue #356

**Issue**: #356 - cdd/operator: δ release gate must block until CI green — not just poll and report  
**Cycle**: 356  
**β**: beta@cdd.cnos  
**Date**: 2026-05-12  

## Review Summary

**Verdict**: APPROVED  
**Rounds**: 1 (no fix rounds required)  
**Merge**: Completed to main at 21:45 UTC  

## Implementation Assessment

**Quality**: High. α delivered a complete, well-scoped solution that directly addresses all ACs.

**Scope adherence**: Excellent. Changes limited to operator/SKILL.md as specified, with proper updates to both §6 Gate and §3.4 for consistency.

**Evidence quality**: Strong. Self-coherence.md provided concrete line references and complete AC mapping.

## Technical Review

**AC Coverage**: All 4 ACs fully satisfied:
- Enhanced §6 Gate step with blocking behavior and recovery ownership
- Complete 5-step recovery runbook 
- Explicit constraint preventing release completion on red CI
- Operator override escape hatch with real-world examples

**Implementation approach**: Sound. Follows established CDD patterns (consistent with β/γ red-blocking) while enhancing δ's existing CI polling infrastructure.

**Risk assessment**: Low. Documentation-only change to role contract, no executable code modifications.

## Process Observations

**α performance**: Strong execution. Complete implementation with thorough self-coherence and proper incremental commits.

**Cycle efficiency**: Single round completion with no findings demonstrates good issue preparation and clear requirements.

**Pattern consistency**: Solution maintains CDD role pattern coherence (β blocks on red, γ blocks on red, now δ blocks on red).

## Release Notes

Addresses known failure pattern from v3.66.0/v3.67.0 where δ reported CI failures but had no prescribed recovery path. Enhanced δ role now owns CI failure recovery with clear escalation protocols.
