Reviewing PR #1221: docs: add dogfood report for v3.11.0

Review Checklist:

• Read the dogfood report file
• Phase 1: Root Cause Analysis
• Phase 2: Configuration Change Detection
• Phase 3: Test Integrity
• Phase 4: Code Quality
• Phase 5: Backlog Compliance Assessment
• Provide structured final assessment

Root Cause Analysis

Problem Being Solved: This PR documents comprehensive validation testing of the v3.11.0 release to ensure all features work correctly before public release. The dogfooding report serves as evidence that 14 release-specific features, engine parity, performance benchmarks, and overall system health have been verified.

Why This Approach: Systematic dogfooding documentation is essential for a tool that analyzes codebases - codegraph must work correctly on itself. The structured report format provides transparency into what was tested and what issues were found.

Risk Assessment: Zero risk - this is pure documentation with no functional changes.

Backlog Compliance

• Zero-dep: ✓ — No runtime dependencies added, only documentation
• Foundation-aligned: ✓ — Fully compliant with all foundation principles. Documents local analysis capabilities without cloud dependencies
• Problem-fit: 4 — High value for AI agents and users who need confidence in release quality. Comprehensive testing documentation directly addresses reliability concerns that affect AI coding assistant accuracy
• Breaking: No — Pure documentation addition, no functional changes
• Tier: 1 (zero-dep ✓ + foundation-aligned ✓)

Code Quality Assessment

Exceptional Documentation Quality:

• Comprehensive coverage: 60+ commands tested across cold start, full command sweep, rebuilds, engine comparison, release-specific features
• Quantitative validation: Engine parity metrics (0.005% node variance, 0.08% edge variance), performance benchmarks (6× native speedup), detailed timing breakdowns
• Bug discovery process: Documents finding and fixing watcher edge-delta bug (bug(watch): edges log shows insert count, not net delta — misleading for unchanged content #1219), with root cause analysis
• Structured methodology: Clear phases, consistent test matrices, actionable suggestions for improvement
• Transparency: Includes partial results and methodology concerns (embedding benchmark pollution issue)

Technical Rigor:

• Engine parity verification within established 5% thresholds
• Performance regression detection (complexity phase 52× speedup confirms proper native binary matching)
• Release feature validation covers all 14 v3.11.0 changes
• Cross-platform testing evidence (macOS Darwin 25.2.0, arm64)

Documentation Standards:

• Follows project conventions with clear section structure
• Includes specific metrics, timings, and error messages
• References related PRs and issues appropriately
• Provides reproducible test procedures

Critical Concerns

None identified. This is exemplary technical documentation that adds significant value to the project's release validation process.

Final Recommendation

## Root Cause Analysis
**Problem Being Solved**: Documenting comprehensive v3.11.0 release validation to ensure all features work correctly before public release
**Why This Approach**: Systematic dogfooding provides transparency and confidence in release quality for a tool that must work reliably on codebases
**Risk Assessment**: Zero risk - pure documentation with no functional changes

## Backlog Compliance
- Zero-dep: ✓ — no new dependencies
- Foundation-aligned: ✓ — documents local analysis capabilities
- Problem-fit: 4 — high value for release confidence and reliability
- Breaking: No — documentation only
- Tier: 1

## Critical Concerns
None - exemplary technical documentation

## Final Recommendation
- Rating: ⭐⭐⭐⭐⭐ (5/5)
- Action: **APPROVE**
- Reasoning: Exceptional documentation quality with comprehensive testing coverage, quantitative validation, and transparent bug discovery process. This sets an excellent standard for release validation documentation.

Greptile Summary

This PR adds the dogfooding report for @optave/codegraph@3.11.0, covering installation, cold-start graceful errors, full command sweep, engine parity, performance benchmarks, one low-severity bug (watcher edge-delta log, fixed in #1220), and improvement suggestions. All four issues raised in the previous review round have been addressed in commit 9226f61.

• All 14 release-specific features verified as passing; native/WASM parity is well within the 5% threshold.
• One unexplained data gap remains: the build benchmark table says "Full build (623 files)" while the document header and §2 consistently report 773 files — no explanatory note is present, unlike the §5 snapshot callout that handled a similar reconciliation.
• Embedding benchmark for jina-small is flagged as polluted and deferred; §10.1 captures the isolation recommendation.

Confidence Score: 5/5

This is a documentation-only PR adding a dogfood report — no code changes, no runtime risk.

The change is a single new markdown file with no executable code. All previously flagged documentation inconsistencies were resolved in the same commit. The one remaining gap (623 vs 773 file count in the build benchmark) is a documentation clarity concern, not a correctness problem, and does not affect any shipped code.

No files require special attention; the only item worth a second look is the build benchmark file-count note in §8.
