Authorization flags:

USER_GO=YES
GPT_FINAL_APPROVAL=YES
DIEU32_SYNTHESIZE_TITLE_POLICY_APPROVED=YES
DIEU32_RETRY_AUTHORIZED=YES

Scope

DIEU-32 only.

Expected current live source count: 23 rows. If live source count, canonical address set, or NULL-body set changed from the investigation, STOP before BEGIN and report SOURCE_DRIFT_REQUIRES_GPT_REVIEW.

Approved synthesize rows must be exactly:

D38-DIEU32-ROOT
D38-DIEU32-S2
D38-DIEU32-S3
D38-DIEU32-S4

All must satisfy:

section_type='heading'
body IS NULL
children > 0

Hard boundaries

Forbidden:

No DDL.
No schema changes.
No trigger/function changes.
No birth-system changes.
No direct INSERT into information_unit or unit_version.
No TAC writes.
No UI cutover.
No Nuxt/Directus/config changes.
No vector/Qdrant mutation or reindex.
No event_outbox/IU event emission work.
No publications beyond DIEU-32.
No touching existing 75 IU rows.
No pattern-matching deletes.
No automatic content repair beyond approved heading-title synthesis.

Allowed:

Use fn_iu_create canonical writer.
Patch identity_profile/content_profile/provenance only for newly captured DIEU-32 rows using allowed marker fn_iu_apply_edit_draft.
Create birth rows via existing trg_birth_information_unit only.
Write rollback-key artifacts to KB + VPS logs before COMMIT.
Exact-key rollback only if needed.

Approved body preparation rule

For each source row:

IF section_type='heading' AND body IS NULL AND children>0 THEN
  iu_body := title
  body_source := 'synthesized_from_title_due_to_tac_heading_null_body'
  src_body_was_null := true
ELSE
  iu_body := body
  body_source := 'preserved_from_tac_unit_version_body'
  src_body_was_null := false
ENDIF

If any non-heading row has body NULL, STOP before BEGIN.

If any heading row with body NULL has children=0, STOP before BEGIN unless it is explicitly reviewed later.

Required preflight

Run live SELECT-only preflight:

• TAC tables exist.
• DIEU-32 publication exists.
• source_count=23.
• render_order contiguous 0..22.
• owner NULL count = 0.
• collisions with existing information_unit.canonical_address = 0.
• body NULL count = 4 and all are approved synthesize rows.
• required vocab keys exist.
• fn_iu_create signature exists.
• gateway mode enforced.
• allowed markers include fn_iu_create and fn_iu_apply_edit_draft.
• edit policy require_review.
• birth trigger exists.
• species primary mapping exists.
• pre-existing IU rows captured; expected 75 if live state unchanged.
• TAC table pre-counts captured.

If any hard preflight fails, STOP before BEGIN.

Transaction execution

Open one transaction.

For each of 23 source rows ordered by render_order:

1. Prepare iu_body using the approved body preparation rule.
2. Call fn_iu_create only:

SELECT public.fn_iu_create(
  p_canonical_address := :src_canonical_address,
  p_title             := :src_title,
  p_body              := :iu_body,
  p_actor             := 'agent:p3d-phase5c2-dieu32-retry',
  p_unit_kind         := 'law_unit',
  p_section_type      := :src_section_type,
  p_owner_ref         := :src_owner,
  p_publication_type  := 'law',
  p_parent_ref        := NULL
);

3. Capture returned IU id, UV id, status, warnings.
4. Patch only captured IU row with identity_profile, including:

{
  "body_source": "<body_source>",
  "tac_provenance": { ... },
  "tac_hierarchy": { ... },
  "publication_authority_ref": "incomex_council",
  "publication_authority_vocab_key": "vocab.publication_authority.incomex_council",
  "rendering": { ... }
}

5. Patch only captured UV row with content_profile/provenance, including:

{
  "body_source": "<body_source>",
  "src_body_was_null": true|false,
  "src_title": "<source title>",
  "src_content_hash": "<tac_unit_version.content_hash>",
  "source_kind": "tac_unit_version",
  "src_unit_version_id": "<uuid>",
  "migrated_by": "agent:p3d-phase5c2-dieu32-retry",
  "migrated_at": "<utc>"
}

Use allowed marker fn_iu_apply_edit_draft for profile/provenance updates.

Rollback key dual-write before COMMIT

Before COMMIT, write exact rollback keys to both:

KB:

knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-dieu32-rollback-keys-<utc>.md

VPS log:

/opt/incomex/logs/p3d-phase5c2-dieu32-<utc>.log

If either write fails, rollback.

Validation before COMMIT

Run V-1..V-7:

• V-1: captured IU/UV/source count = 23.
• V-2: render order fidelity 0..22.
• V-3a: IU-side hash consistency.
• V-3b': conditional body policy:
  • preserved rows: unit_version.body = tac_unit_version.body.
  • synthesized rows: unit_version.body = tac_logical_unit.title, section_type='heading', source body IS NULL, children>0, body_source flags present, src_body_was_null=true.
• V-3c: TAC hash provenance preserved in content_profile.src_content_hash.
• V-3d: cross-system hash equality report-only, not gate.
• V-4: authority incomex_council.
• V-5: birth coverage for 23 captured IU rows.
• V-6: TAC source untouched.
• V-7: fn_iu_verify_invariants PASS for captured rows.

If any required validation fails, rollback.

Post-COMMIT validation

After COMMIT:

• gateway triggers attached and marker not leaked.
• pre-existing 75 IU rows untouched.
• rollback keys exist in KB + VPS log.
• final IU count = pre + 23.
• final UV count = pre + 23.
• final birth IU count = pre + 23.
• TAC table counts unchanged.
• UI/vector/bulk flags false.

If post-COMMIT validation fails, exact-key rollback for DIEU-32 only.

Strategic note

In the report, include a section:

Policy extracted for dot-iu-cutter v0.1

Explain how this heading-container policy should be implemented in the automated cutter so future Cắt luật A flows do not rediscover this issue.
