Top Findings/Assumptions to Verify

1. TAC hash = sha256(body+title+description+profile)? — composite payload hypothesis from P5 §5.2
2. IU hash = sha256(body::bytea) — confirmed but agent should re-confirm
3. law_unit not in vocab seed? — possibly only design_doc_section seeded
4. Planner fallback logic — may have default unit_kind when caller input not in vocab
5. TAC vocab tables exist and have data — section_type, lifecycle, review_state, publication_type

Recommended Next Action

GPT review → approve → dispatch investigation prompt → agent reports findings → GPT decides hash policy + planner fix → Phase 4 pilot migration design.
