Verdict

Status: PHASE5C2_86_UNITS_COMPLETE__AUTHORIZE_DOT_IU_CUTTER_V0_1_DESIGN

Phase 5C2 TAC→Information Unit migration for the three current TAC publications is complete.

Accepted DIEU-32 retry

The DIEU-32 retry is accepted:

• 23/23 rows committed.
• 4 heading-container rows used approved synthesize_title policy.
• 19 rows preserved verbatim.
• Conditional V-3b' PASS.
• Birth coverage PASS.
• Gateway integrity PASS.
• Existing 75 IU rows untouched.
• TAC source untouched.
• Rollback keys written to KB + VPS log before COMMIT.

Approved policy to carry forward:

IF section_type='heading' AND body IS NULL AND children>0 THEN
  body_source='synthesized_from_title_due_to_tac_heading_null_body'
  iu_body=title
ELSE IF body IS NOT NULL THEN
  body_source='preserved_from_tac_unit_version_body'
  iu_body=body
ELSE
  BLOCK
ENDIF

Important boundary

This is not UI cutover. This is not vector enablement. This is not TAC deprecation. TAC remains canonical UI source until a separate UI/IU rendering cutover design is reviewed and approved.

Strategic decision

Manual batch migration should now stop as the main mode. The next mainline is productionizing the learned orchestration pattern into a reusable automated cutter.

User target:

Cắt luật A

The system must then automatically:

• locate source;
• discover/segment or read TAC units;
• classify body policy;
• validate vocab/species/birth/gateway;
• create IU/UV via canonical writer;
• fire birth;
• write rollback keys;
• attach provenance;
• report completion;
• later propose/create professional edges.

Design only. No implementation yet.

Required design priorities

The design must preserve the exact safety lessons from Phase 5C2:

• PG-first / live evidence driven.
• fn_iu_create canonical writer only.
• No direct IU/UV insert.
• Per-publication bounded transaction.
• Dual-write rollback keys before COMMIT.
• Exact-key rollback only.
• Patched V-3 semantics.
• Heading-container synthesize-title policy.
• No UI cutover.
• No vector/Qdrant work.
• No bulk hidden migration.
• No hardcoded document-specific arrays.
• Parameterized doc_code operation.
• Produce per-run report and consolidated status.
