dot-iu-cutter v0.1 — P0 Migration Design Risk & Coverage Report
dot-iu-cutter v0.1 — P0 Migration Design Risk & Coverage Report
Date: 2026-05-15 Status: P0 MIGRATION DESIGN PHASE — COMPLETE (DESIGN ONLY) Scope: DESIGN ONLY. No code, no DDL, no SQL, no CREATE/ALTER TABLE, no column DDL, no migration execution, no PG mutation, no Qdrant mutation, no implementation planning, no implementation execution.
1. Purpose
Synthesize the P0 Migration Design Package: list all files, confirm dependency-graph integrity, summarize per-item Đ32 risk reviews, consolidate unresolved decisions, verify P0 coverage, list blockers before implementation planning, and explicitly confirm that no executable artifacts were produced.
2. Files Created in This Phase

[P0 design complete]
Dependency integrity check: Each downstream item has its upstream dependencies explicitly named in its § Dependencies section. No cycles. FK references are forward-only (downstream → upstream).
Shared artifact: dot_pair_signature table is jointly designed in P0-3 §4.3 and referenced by P0-4 §4.1; satisfies Đ44 Step 2 joint ratification (cut_change_set + verify_result).
Joint design pairs:
- P0-2 envelope + unit_block (composite identity; per Đ44 Step 1)
- P0-3 + P0-4 (shared DOT-pair signature schema; per Đ44 Step 2)
4. Per-Item Đ32 Risk Review Summary
| Item | Proposed risk class | Đ32 review status | Key Đ32 attention |
|---|---|---|---|
| P0-5 decision_backlog_entry | Standard | NOT_STARTED | History preservation across rollback; PII handling for owner_seat; markdown mirror access scope |
| P0-1 canonical_address | Standard | NOT_STARTED | Backfill data exposure; authority misclassification cross-link Đ0-G; trigram index PII concern (FUTURE) |
| P0-2 manifest_envelope + unit_block | Standard | NOT_STARTED | Vocabulary leakage (Đ24 discipline); source_span correctness; review_required stickiness |
| P0-6 review_decision | Standard | NOT_STARTED | AI reviewer independence; cross_signed_by_dot_verifier enforcement; reviewer_identity PII |
| P0-3 cut_change_set + rollback_key | HIGH | NOT_STARTED | Criterion 28 enforcement; rollback test plan REQUIRED; signing scheme placeholder acceptance; before_state_snapshot granularity; cascade default ERROR |
| P0-4 verify_result | HIGH | NOT_STARTED | Criterion 28 concurrent with P0-3; verifier independence; canonicalization rule binding; axis-2 advisory boundary; rollback chain test plan |
Risk class distribution: 4 Standard, 2 HIGH.
Joint Đ32 review recommendation: P0-3 + P0-4 reviewed together (they share DOT-pair signature schema and dual-signature rule). All HIGH-risk Đ32 review must precede any migration execution.
Đ32 review authority per item (all in NOT_STARTED state):
p0_5: Đ32 + Registry Custodian (G-2) co-sign
p0_1: Đ32 + Đ24 vocab owner + Đ0-G birth-gate owner
p0_2: Đ32 + Đ44 family registry custodian + Đ24 vocab owner
p0_6: Đ32 + Đ44 + Đ37 + G-5 (PII handling)
p0_3: Đ32 (HIGH) + G-4 DOT Registry Custodian + Đ44 + Đ37
p0_4: Đ32 (HIGH) + G-4 DOT Registry Custodian + Đ44 + Đ24 + Đ37
5. Unresolved Decisions (Consolidated)
Aggregated from each per-item design's open-decisions section. None block design completion; all gate Đ32 review and/or migration execution.
5.1 Cross-Cutting Decisions
| ID | Decision | Affects | Recommendation |
|---|---|---|---|
| X-1 | Schema placement: TAC schema vs new schema class | P0-2, P0-3, P0-4, P0-5, P0-6 | New schema class for governance/manifest family; Đ44 + Đ33/Đ43 confirm |
| X-2 | Primary ID form: uuid vs bigserial vs deterministic text | All items | uuid for global uniqueness; human-readable aliases where useful (e.g., decision_id_human in P0-5) |
| X-3 | JSONB schema validation: PG jsonb_check vs application-only | All items with JSONB fields | application-layer v0.1; PG jsonb_check FUTURE |
| X-4 | Enum implementation: PG enum type vs Đ24 lookup table FK | All items with enum fields | Đ24 lookup FK for vocabulary discipline |
| X-5 | Markdown mirror generator location & cadence | P0-5 | sweep-triggered batch; implementation FUTURE |
5.2 P0-5 Specific Open Decisions
P0-5 §9 items 1–10: schema placement, primary ID, enum implementation, owner_role shape, dependency cycle detection, priority field placement, closure_evidence JSONB validation, mirror generator location, re_opened state distinctness, history granularity.
5.3 P0-1 Specific Open Decisions
P0-1 §9 items 1–10: uniqueness scope, mutation policy, indexing strategy, alias storage, birth_gate_class field, backfill strategy, format extensions, address for non-law artifacts, constraint enforcement, NULL on legacy rows.
5.4 P0-2 Specific Open Decisions
P0-2 §9 items 1–11: schema placement, composite identity enforcement, source_revision shape, source_span unit (cross-link P0-4 §6), source_span as integers vs JSONB, confidence shape, block_state/state enum elevation, cut_reason_tags shape, manifest diff materialization, report_summary JSONB shape, decision_backlog_root_entry_id semantics.
5.5 P0-6 Specific Open Decisions
P0-6 §9 items 1–10: schema placement, verdict enum elevation, reviewer_identity validation, re-review handling, reviewer independence enforcement, AI/Human/Council distinction, escalation_ref cardinality, findings completeness, PII handling, cross_signed_by_dot_verifier semantics.
5.6 P0-3 Specific Open Decisions (HIGH risk)
P0-3 §9 items 1–12: schema placement, signing scheme placeholder, rollback_key format, cascade rules, before_state_snapshot granularity, affected-row tracking shape, shared dot_pair_signature, payload_envelope strictness, state enum extension, idempotency key, rollback authority, signature revocation.
5.7 P0-4 Specific Open Decisions (HIGH risk)
P0-4 §12 items 1–10: axis_1_drift_unit (joint with P0-2), canonicalization rule, axis_2_coverage_score formula, axis_2_advisory_findings validation, drift_threshold non-zero allowance, verdict_rationale enforcement, disagreement-handling races, signature collection timeout, multiple VERIFY runs chain, rollback chain cycle.
5.8 Critical Joint Decisions (must resolve together)
| Joint decision | Items involved | Why joint |
|---|---|---|
source_span unit (P0-2) ↔ axis_1_drift_unit (P0-4) |
P0-2 §9 item 4 + P0-4 §6 + §12 item 1 | MARK-span and VERIFY-drift must align or round-trip fails systemically |
| Schema placement (X-1) | P0-2, P0-3, P0-4, P0-5, P0-6 | All new tables share schema class decision |
Shared dot_pair_signature table |
P0-3 §4.3 + P0-4 §4.1 | Already jointly designed; Đ32 review jointly |
| Both-signatures + drift rule enforcement | P0-3 §7 + P0-4 §9 §10 | Criterion 28 binding; enforce together |
| Primary ID form (X-2) | All items | Cross-table FK consistency |

12. Recommended Next Steps (NOT executed by Agent)
- GPT review of this design package (8 files).
- If PASS → Đ32 risk review per P0 item (6 reviews; jointly review P0-3 + P0-4).
- Per-item Đ32 outputs feed operational decision resolution for cross-cutting + critical joint decisions.
- Operational seat naming for 5 governance gaps (separate operational phase).
- G-3 D4 capability intake for executor/verifier boundary (post-G-3 operational seat).
- Canonicalization rule v0.1 finalization documented (P0-4).
- Rollback test plan documented and executed dry-run (P0-3 + P0-4).
- Implementation Planning Package prompt approval (separate prompt; similar to P0 Migration Design prompt approval).
- Implementation Planning phase produces execution-stage design (still no execution).
- Final risk review signs migration execution authorization.
- Migration execution begins (FIRST time code/DDL/migration is allowed).
Each numbered step above is a separate phase or session, not part of this design package.
