# β Close-out — Issue #292

**Issue**: #292 - Resumption protocol for partial CDD artifacts: section manifest + §1.4 expansion  
**Cycle**: 292  
**β**: beta@cdd.cnos  
**Date**: 2026-05-12  

## Review Summary

**Verdict**: APPROVED  
**Rounds**: 1 (no fix rounds required)  
**Merge**: Completed to main at 23:00 UTC  

## Implementation Assessment

**Quality**: Outstanding. α delivered a comprehensive resumption protocol that perfectly addresses the genus-level problem.

**Meta-pattern excellence**: This cycle exemplifies CDD self-improvement. The implementation demonstrates its own solution—section manifest format proven through the very artifact documenting it.

**Scope**: Complete coverage across CDD.md core + all 3 role skills. No gaps or shortcuts.

## Technical Review

**Protocol design**: 4-step resumption process is precise and actionable. HTML comment manifest format is clean and functional.

**Integration**: Extends existing §1.4 large-file authoring rule without breaking changes. Forward-compatible with cn resume directive.

**Practical validation**: Addresses real friction from #283 β timeout. Section manifest commits prove the concept works.

## Process Observations

**Incremental commits demonstration**: Self-coherence.md written as 7 incremental commits, each updating the completed manifest. Beautiful proof-of-concept for the protocol.

**CDD self-modification**: Classic pattern—protocol gap identified, systematic solution implemented across canonical surfaces, immediately applied to its own execution.

**Worked example value**: AC5 fulfilled ingeniously by making the implementation artifact serve as its own demonstration.

## Release Notes

Resumption protocol for partial CDD artifacts. Session interruptions during large-file authoring can now recover cleanly via section manifests. Prevents data loss while maintaining section-by-section discipline. Addresses #283 pattern and provides genus-level solution.
