## Detailed Findings

### Implementation Quality

**✅ Strengths:**
1. **Complete Phase 5 & 6 Implementation:** Both phases fully implemented in SKILL.md with detailed steps (5.1-5.2 for Phase 5, 6.1-6.2 for Phase 6)
2. **Comprehensive Reference Documentation:** `output-quality-heuristics.md` provides detailed formulas, schemas, and edge cases across 7 sections
3. **Deterministic Scoring:** Quality computation explicitly excludes LLM calls, uses only algorithmic formulas
4. **Quality Thresholds Well-Defined:** Three-tier classification (high/acceptable/low) with specific score ranges and warnings
5. **KB Pipeline Compatibility:** Output format matches EPIC-049 conventions (.kb-intake/ folder, .kb-index.json schema)
6. **Non-Blocking Quality:** Low quality scores generate warnings but do not prevent packaging (per BR-1)
7. **Idempotent Packaging:** Re-running Phase 5 produces identical output (NFR-4)
8. **Proper Cleanup:** Temporary files removed while preserving audit trail (manifest + packed content)

**📋 Observations:**
1. **Minor Naming Discrepancy:** SKILL.md:375 references `{checkpoint_path}/content/` for cleanup, but Phase 2 context suggests this refers to the `extracted/` directory from Phase 2 extraction. The intent is clear (remove temp extraction files), though consistent naming would improve clarity.
2. **All 24 ACs Have Evidence:** Every acceptance criterion has clear, traceable implementation in the deliverables
3. **Edge Cases Documented:** output-quality-heuristics.md §7 covers 12 edge case scenarios

### Test Coverage

All 24 acceptance criteria have been evaluated against the deliverables:
- **Group 1 (Quality Scoring):** 8/8 passed — complete 4-dimension scoring formula implementation
- **Group 2 (Quality Thresholds):** 4/4 passed — threshold classification and warning logic verified
- **Group 3 (KB Article Packaging):** 5/5 passed — .kb-intake/ folder structure and file formats confirmed
- **Group 4 (Extraction Report):** 3/3 passed — report structure and sorting requirements met
- **Group 5 (Completion & Handoff):** 4/4 passed — manifest finalization and cleanup procedures verified

### Traceability

- **Specification → Implementation:** All 24 ACs directly traceable to specific line numbers in SKILL.md or output-quality-heuristics.md
- **Cross-References:** SKILL.md consistently references output-quality-heuristics.md for detailed formulas (§1-§7)
- **Schema Compliance:** .kb-index.json and article frontmatter schemas fully documented in reference file
- **Output Result Alignment:** Phase 5 outputs (extraction_status, quality_score, quality_label) match Output Result YAML structure

## Conclusion

**FEATURE-050-E (KB Intake Output & Quality Scoring) is COMPLETE and READY FOR PRODUCTION.**

All 24 acceptance criteria have been implemented and verified through structured review. The deliverables demonstrate:
- Complete Phase 5 implementation with deterministic quality scoring and KB article packaging
- Complete Phase 6 implementation with manifest finalization and cleanup
- Comprehensive reference documentation for scoring formulas, schemas, and edge cases
- Full compliance with EPIC-049 KB intake pipeline conventions
- Proper error handling, edge case coverage, and idempotent behavior

**Recommendation:** APPROVE for merge. No blocking issues identified.

**Next Steps:** Feature ready for workflow completion (FEATURE-050-E-closing) and integration with EPIC-049 KB librarian pipeline.
