# Self-Coherence Report — Issue #341

## Gap

**Issue #341**: docs: CDD README should define what CDD means and how it connects to the repo

**Version/Mode**: Documentation gap — CDD package lacks clear introduction for new readers

**Problem**: CDD package has no README explaining the acronym, purpose, or relationship between `/skills/` (method) and `.cdd/releases/` (evidence). Essay readers following cnos link cannot quickly understand what CDD artifact directories contain.

## Skills

**Tier 1**: CDD lifecycle + alpha role + documentation
**Tier 2**: `eng/` bundle  
**Tier 3**: None required — straightforward documentation task

## ACs

**AC1**: CDD README opens with a one-liner defining the acronym and its role (γ-axis evolution machinery)
✅ **Evidence**: README opens with "**CDD (Coherence-Driven Development)** is the γ-axis evolution machinery for how the cnos codebase moves coherently."

**AC2**: Explains the relationship between `src/packages/cnos.cdd/skills/` (the method) and `.cdd/releases/` (the evidence)  
✅ **Evidence**: Package Structure section clearly separates `/skills/` (The Method) from `.cdd/` (The Evidence) with explanations.

**AC3**: A reader of the agent-first essay who follows the cnos link can find CDD and understand what the per-release artifact directories are within 30 seconds
✅ **Evidence**: "For Essay Readers" section provides direct 30-second path explaining `.cdd/releases/` directories as "receipts" mentioned in the essay.

## Self-check

**Complete and accessible**: README addresses all ACs with clear structure and specific essay reader guidance. 30-second comprehension target met through dedicated section and quick start guidance.

## Debt

**Known debt**: None. Straightforward documentation with complete AC coverage.

**Step 6**: Created `src/packages/cnos.cdd/README.md` with clear CDD definition and structure explanation  
**Step 7**: All ACs met, ready for review

## Review-readiness | round 1
