  3. Edge reassignment audit trail (D3)
  4. Alias / redirect table for superseded units (D3)

7. Law Conflict Status

No unresolved law conflict at design phase completion.

Conflict watchlist (Checkpoint 0 §8) reviewed in D10 §8. All items either resolved or deferred to governance via D5 backlog. Design phase MAY proceed to user review and (after approval) implementation planning.

8. Missing Instrumentation (criterion 11, 20)

Items classified requires_instrumentation and still missing:

  1. Retrieval logs / event capture (D11) — thread_hit_rate, fallback_vector_rate, context_sufficiency_rate, etc.
  2. Co-edit detection (D3, D9) — change-set proximity capture.
  3. Co-citation capture (D3, D9) — citation graph extraction.
  4. Co-retrieval capture (D3, D9) — depends on (1).
  5. CDC plumbing (D9) — PG trigger + NOTIFY/LISTEN for birth events.
  6. Thread centroid embedding (D11) — per-thread aggregate embedding for ranking.
  7. Health-score aggregator (D3) — view/materialized-view refresh policy.
  8. DOT-pair signature recording (D1) — dual signature envelope on REPORT.
  9. Auth-context propagation (D11) — role/scope to retrieval layer.

These are named, not built, in v0.1 design.

9. Open Questions (consolidated)

From each deliverable (selected; full list per deliverable):

  1. Should dot-iu-cutter-verify be separate code path or --verify mode? (D1)
  2. Where does the independent-AI reviewer run? (D1)
  3. Per-unit blocks: child rows vs JSONB? (D2)
  4. How does Đ24 self-extend (vocabulary-of-vocabulary)? (D2)
  5. Exact threshold values for D3 signal scoring. (D3)
  6. Co-edit instrumentation reliance on current CDC. (D3, D9)
  7. Fixed vs learned weights for coupling_score. (D3)
  8. Auto-accept thresholds + material-difference thresholds (D9).
  9. semantic_thread final placement if universal_edges insufficient (D9, D10).
  10. Heterogeneity measure for overbroad detection (D9).
  11. Negative knowledge decay policy (D9).
  12. thread_hit_rate initial target value (D11).
  13. Embedding scheme for thread centroids (D11).
  14. Audience formal definitions (employee/partner/customer) (D11).
  15. wrong_audience_result rollback policy (D11).
  16. Context Pack caching policy (D11).
  17. Self-Review cadence defaults (D4).
  18. Impact diff auto-generation vs hand-authored (D4).
  19. Tool revision propagation to verifier (D4).
  20. Default next_review_date per risk/kind (D5).
  21. Auto-resolve on signal silence: yes/no (D5).
  22. Backlog scope: cutter-only vs federated (D5).
  23. Manifest/Review/Cut/Report families: separate or unified (D7).
  24. semantic_thread family placement in UOSL (D7).
  25. Maturity ladder ↔ tool revision interaction (D7).
  26. Multi-valued labels first-class vs profile JSON (D7).

Governance closure recommendations (D10 §9) feed these questions to Đ37 / Đ44 / Đ32 owners.

The design phase is complete and self-consistent. No code, no DDL, no migration, no PG mutation, no vector work, no UI build was performed. All 11 deliverables exist at knowledge/dev/laws/dieu44-trien-khai/design/. All 56 questions and 50 acceptance criteria are covered.

Recommended next step:

  1. User review of the 11 deliverables + Checkpoint 0. Focus on:
    • D7 / D10 governance closures (UOSL family decisions, Đ37 role closures).
    • Auto-accept thresholds (D9) and retrieval metric targets (D11).
    • Threading PG placement decision (D9 / Đ33 / Đ39).
  2. Governance routing of the open questions in §9 to Đ37, Đ44, Đ32 owners via Decision Backlog Registry (D5).
  3. Closure of Family Registry entries for new object families (D7 §6 items 47–52) at Đ44 governance.
  4. Schema gap prioritization for migration planning (a separate phase, not this design phase). Suggested priority: critical-path fields for axis-1/axis-2 first (D6 §6), then manifest envelope (D2 §6), then threading (D9 §6), then retrieval instrumentation (D11 §6).
  5. Only after governance closure and User PASS on this design phase, implementation planning may begin under standard Đ32/Đ37 controls. Implementation is not authorized by this design phase.
