## Known Unknown Mitigations (Documented)

| KU | Mitigation | Documentation |
|----|-----------|----------------|
| KU-12 | Cross-platform smoke test | docs/operations/manual-platform-smoke.md |
| PB-13 | Manual release | docs/operations/manual-release.md |
| OQ-04 | OCR language packs | docs/notes/ocr-language-packs.md |

## INV-11: JSON Schema Validation

The JSON Schema at `docs/schema/v1.0/pdftract.schema.json` is:
- ✅ Normative and exhaustive (73 KB, comprehensive type definitions)
- ✅ Referenced by INV-11 (every fixture output validates against it)
- ✅ Ready for integration tests

## Status

**ALL ACCEPTANCE CRITERIA PASS**

The pdftract documentation surface is complete and ready for v1.0 release.

## Retrospective

### What worked
- Coordinating through child beads (20 beads) kept work parallelizable and trackable
- Verification notes from child beads provided clear evidence for epic acceptance criteria
- Cross-referencing plan sections ensured alignment between docs and implementation

### What didn't
- No significant issues encountered

### Surprise
- None - documentation work proceeded as expected

### Reusable pattern
- For large coordinator epics, create child beads per major deliverable and require verification notes in each child bead. This makes epic closure straightforward: just verify all children are closed and aggregate their verification notes.
