2. Per-publication summary

2.1 DIEU-35 (36 rows, R1 retry)

  • Detailed report: knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-r1-dieu35-retry-patched-v3-execution-report.md
  • Rollback-keys KB: knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-dieu-35-rollback-keys-20260514T140804Z.md
  • VPS log: /opt/incomex/logs/p3d-phase5c2-dieu-35-20260514T140804Z.log
  • All 36 rows preserved (no synthesize). Soft-flag D38-DIEU35-S8-P3 (body_char=1) migrated verbatim.

2.2 DIEU-28 (27 rows, R2)

  • Detailed report: knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-r2-dieu28-pilot-migration-execution-report.md
  • Rollback-keys KB: knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-dieu-28-rollback-keys-20260514T140835Z.md
  • VPS log: /opt/incomex/logs/p3d-phase5c2-dieu-28-20260514T140835Z.log
  • All 27 rows preserved. 5 heading-container rows used body='' (empty string), which fn_iu_create accepts → no synthesize branch needed.

2.3 DIEU-32 (23 rows, R2 retry with synthesize-title policy)

  • Detailed report: knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-r2-dieu32-retry-synthesize-title-execution-report.md
  • Rollback-keys KB: knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-dieu32-rollback-keys-20260514T144644Z.md
  • VPS log: /opt/incomex/logs/p3d-phase5c2-dieu32-20260514T144644Z.log
  • 4 rows synthesized (body = source.title, body_source='synthesized_from_title_due_to_tac_heading_null_body'): D38-DIEU32-ROOT, D38-DIEU32-S2, D38-DIEU32-S3, D38-DIEU32-S4 — all section_type='heading' AND body IS NULL AND children > 0.
  • 19 rows preserved verbatim.

3. Patched V-3 semantics — final form (verified across 86 rows)

Sub-gate Spec Cumulative result
V-3a IU-side hash consistency uv.content_hash = fn_content_hash(uv.body) 86/86 PASS
V-3b' Body preservation (conditional) body_source='preserved_…' ⇒ byte-equality with source body; body_source='synthesized_…' ⇒ equality with source title + flags + section_type='heading' + src_body_was_null=true + children>0 82 preserved (byte-eq 82/82) + 4 synthesized (all conditions 4/4) = 86/86 PASS
V-3c TAC hash provenance content_profile.src_content_hash = tac_unit_version.content_hash 86/86 PASS
V-3d Cross-system hash equality REPORT ONLY, not a gate 0/86 (expected legacy divergence)

The patched V-3 semantics generalize cleanly across:

  • Publications with no NULL bodies (DIEU-35, DIEU-28) — synthesize branch never fires.
  • Publications with NULL bodies on heading containers (DIEU-32) — synthesize branch fires deterministically only for those rows.
  • The body-source flag is recorded on both identity_profile and content_profile and verified to match for every captured IU/UV pair.

4. Hard-boundary compliance (cumulative across the 3 publications)

Boundary Compliance
No DDL / no schema / no trigger or fn change / no birth-system change ✅ across all 3
No direct INSERT to IU/UV — only fn_iu_create ✅
No TAC writes (V-6 PASS thrice) ✅
No UI cutover / Nuxt / Directus / config / vector / event_outbox ✅
No bulk migration beyond DIEU-35/28/32 ✅
Pre-existing 12 pilot/test IU rows untouched throughout ✅
No pattern-matching DELETE; rollback-key dual-write before each COMMIT ✅ (no rollbacks needed; one in-tx abort on R1-first occurred via psql crash; one in-tx abort on the corrected V-3b' attempt; both transactional, no residue)
No automatic content repair beyond approved heading-title synthesis ✅ — non-heading NULL bodies would have raised EXCEPTION in the DO block (BLOCK branch)

5. Toward dot-iu-cutter v0.1 — distilled mandatory capabilities

This run validates the architecture for the future automated cutter ("Cắt luật A"). The capabilities the cutter must implement, distilled from the three published reports:

5.1 Live, parametric, deterministic pipeline

  1. Source discovery — FK-driven join tac_publication → tac_publication_member → tac_logical_unit → tac_unit_version filtered by doc_code; recursive CTE for hierarchy depth. No hand-crafted SQL per publication.
  2. Preflight gate runner (--doc_code) — 19 hard gates: TAC tables exist, publication exists, member_count>0, render_order contiguous, owner-NULL=0, body-NULL classification (must match synthesize policy below), collision count, vocab coverage, fn signature, gateway mode, edit policy, birth trigger, species map, pre-existing IU snapshot, TAC pre-counts, soft-flag scan.
  3. Per-row classifier with explicit policy:
    • SYNTHESIZE_TITLE iff section_type='heading' AND body IS NULL AND children>0 → body = source.title; provenance flagged.
    • PRESERVE iff body IS NOT NULL → body = source.body; provenance flagged.
    • BLOCK iff body IS NULL AND not heading-container → abort.
  4. Bounded transaction per publication: 1 BEGIN, N × (fn_iu_create + SET LOCAL marker + 2 UPDATEs), capture arrays into transaction-local GUCs, then validation, then COMMIT or ROLLBACK. Wall-clock ≤1s per 36 rows observed.
  5. Rollback-key dual-write before COMMIT — KB upload (agent-data MCP API) + VPS log file (with sync). Both must succeed before COMMIT; abort otherwise. This run verified the pattern with revisions 1 (DIEU-35), 1 (DIEU-28), 1 (DIEU-32 first attempt aborted via psql crash; KB doc retained as historical evidence), and 1 (DIEU-32 retry, the binding one).
  6. Patched V-3 (V-3a/V-3b'/V-3c gates; V-3d report-only) + V-1/V-2/V-4..V-7 inside the transaction + V-8..V-10 post-COMMIT.
  7. Exact-key rollback if post-COMMIT validation fails — captured UUID arrays only, no pattern matching.
  8. Per-publication and consolidated reports auto-generated from a structured summary JSON.

5.2 Validation contract (the cutter's promise)

For every committed publication the cutter guarantees:

  • IU/UV/birth count equality with source count.
  • render_order multiset equality with source.
  • IU-side hash consistency (V-3a) 100%.
  • Conditional body fidelity (V-3b') 100% per body_source branch.
  • TAC hash provenance (V-3c) 100%.
  • Authority on all rows.
  • Birth coverage with information_unit_atom / atom species 100%.
  • TAC source counts unchanged.
  • fn_iu_verify_invariants PASS per row.
  • Gateway triggers attached + marker clean after COMMIT.
  • Pre-existing IU rows untouched.
  • Rollback-keys artifact persisted in both KB and VPS log.

5.3 Operator UX

Target invocation (future):

# Read-only check
dot-iu-cutter check --doc_code DIEU-35

# Read-only mapping artifact (R0-equivalent)
dot-iu-cutter map --doc_code DIEU-35 --output kb://artifacts/...

# Bounded migration (single publication, all gates, dual-write rollback)
dot-iu-cutter migrate --doc_code DIEU-35

# Status across publications
dot-iu-cutter status

Behind the scenes, the orchestrator logic from this 86-unit run becomes the cutter's internal state machine.

5.4 Out-of-scope for v0.1 (future passes)

  • IU parent FK enrichment (information_unit.parent_or_container_ref populated from identity_profile.tac_hierarchy.src_parent_canonical_address once all rows exist).
  • UI cutover from TAC reader to IU reader.
  • IU vector collection provisioning.
  • IU event emission to event_outbox.
  • TAC compatibility view (tac_logical_unit → information_unit WHERE unit_kind='law_unit').

These are tracked as separate design packs.
