3. Stage 2-3 — Bounded transaction execution
Single transaction opened via long-lived psql session through docker exec -i postgres psql -U directus -d directus -q -A -t -F '|' -v ON_ERROR_STOP=1.
3.1 BEGIN + DO-block
The DO-block (1.5s wall-clock) iterated through DIEU-35 source rows in render_order order. For each row:
- Called
public.fn_iu_create(p_canonical_address, p_title, p_body, 'agent:p3d-phase5c2-r1', 'law_unit', section_type, owner, 'law', NULL)→ returnedjsonbwithstatus='created',iu_id,uv_id,content_hash,birth_verified=true,invariants_verified=true,unit_kind='law_unit',section_type=<src>,version_seq=1. - Switched
app.canonical_writer = 'fn_iu_apply_edit_draft'(allowed marker), then UPDATEinformation_unitto merge the 10-keyidentity_profilepatch + setdoc_code='DIEU-35',sort_order=render_order,section_type=<src>,section_code=<src>. - UPDATE
unit_versionto mergecontent_profilepatch +provenance='tac:DIEU-35:<src_unit_version_id>'. - Reset marker for next iteration.
After 36 iterations, the loop count and four UUID/text arrays were stashed into transaction-local GUCs (app.r1_iu_ids, app.r1_uv_ids, app.r1_addrs, app.r1_codes).
A single NOTICE was emitted by fn_iu_create per fn_iu_create_preflight() for P-pub1 missing — production sẽ BLOCK (existing pilot-mode behavior; informational only).
3.2 Captures (Stage 3)
CAP_loop_count=36
CAP_iu_ids: 36 UUIDs
CAP_uv_ids: 36 UUIDs
CAP_addrs: 36 D38-DIEU35-* canonical_addresses (ROOT, S0..S15, S4-P1..P4, S4-P1-1..3, S6-P1..P7, S8-P1..P5)
CAP_codes: 36 'information_unit::<uuid>' entity codes
First 3 captured IU/UV pairs (full list in rollback-keys KB doc):
0 D38-DIEU35-ROOT iu=4aec026b-… uv=8738bf75-…
1 D38-DIEU35-S0 iu=4076eb1f-… uv=56484e66-…
2 D38-DIEU35-S1 iu=406f01fe-… uv=f185f049-…
4. Stage 4 — Rollback-key dual-write BEFORE COMMIT
Per prompt §3 Stage 4 + design §8: rollback keys MUST be persisted to both KB and VPS log BEFORE COMMIT; if either write fails → ROLLBACK and STOP.
| Write | Path | Result |
|---|---|---|
| VPS log | /opt/incomex/logs/p3d-phase5c2-r1-dieu35-20260514T103008Z.log |
OK (17,802 bytes; rollback bundle wrapped between ###ROLLBACK_KEYS_BEGIN### / ###ROLLBACK_KEYS_END### markers; sync issued) |
| KB | knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-r1-dieu35-rollback-keys-20260514T103008Z.md |
200 / "status":"created" / revision 1 via POST /mcp/tools/upload_document |
Both writes succeeded. The transaction remained open. Stage 5 validation proceeded.
(Note: after the rollback decision, the rollback-keys KB doc was patched to revision 2 with a "ROLLBACK EXECUTED" note explaining that the UUIDs in that document do not exist in the live DB. The document is preserved for evidence and to demonstrate that dual-write was operational before the rollback decision.)
5. Stage 5 — In-transaction validation V-1..V-7
| Gate | Spec | Live result | Verdict |
|---|---|---|---|
| V-1 row accounting | captured_iu_count=36, captured_uv_count=36, source_count_live=36 |
36 / 36 / 36 |
PASS |
| V-2 render fidelity | identity_profile.rendering.render_order multiset = 0..35 |
multiset = 0,1,...,35; distinct=36 |
PASS |
| V-3a IU-side hash consistency | each captured UV content_hash = fn_content_hash(body) |
36 / 36 match | PASS |
| V-3b TAC cross-system hash match | per UV content_hash matches the corresponding source tac_unit_version.content_hash (where source non-null) |
0 / 36 match | FAIL |
| V-4 authority | all 36 IU identity_profile.publication_authority_ref = incomex_council |
36 / 36 match | PASS |
| V-5 birth coverage | 36 birth rows for captured entity codes; 0 NULL species; all information_unit_atom / atom |
36 birth · 0 NULL · 36 atom species · 36 atom composition | PASS |
| V-6 TAC source untouched | 4 TAC counts equal pre-snapshot | pub 3=3 · lu 86=86 · uv 86=86 · pm 86=86 | PASS |
V-7 fn_iu_verify_invariants |
per captured canonical_address, all_pass=true |
36 / 36 PASS (also enforced internally by fn_iu_create) |
PASS |
→ V-3b FAIL drives ROLLBACK per prompt §3 Stage 5.
5.1 Root cause of V-3b fail
fn_content_hash(p_body text) RETURNS text = encode(digest(p_body, 'sha256'), 'hex') — pure SHA-256 of the body string.
Live read-only sample (post-rollback) for first 5 DIEU-35 rows:
| canonical_address | TAC content_hash |
fn_content_hash(body) |
fn_content_hash(title‖body) |
|---|---|---|---|

TAC's content_hash was computed by an upstream TAC ingest process using a different scheme than fn_content_hash. Specifically:
- TAC hash ≠ sha256(body)
- TAC hash ≠ sha256(title + body)
- The exact TAC algorithm is not documented in this session's KB context; it may include additional structured content (e.g. JSONB normalized form, metadata, or canonical_address prefix) or use a different digest pipeline.
Critically: V-3a confirms that the BODY BYTES were preserved verbatim from TAC into unit_version.body (since fn_content_hash(unit_version.body) = unit_version.content_hash for all 36 rows, and unit_version.content_hash was derived from the body we passed). The cross-system hash MISMATCH is a hashing-scheme divergence, not a content corruption.
This finding was not anticipated by the R0 mapping artifact (which recorded TAC content_hashes but did not verify they would re-derive from the body via fn_content_hash). The R0 design §7 V-3 specification has two sub-bullets:
V-3 content_hash fidelity: per-row UV
content_hash = fn_content_hash(body) = src content_hash
The chained equality assumes TAC and IU use the same hash function over the same input. Live evidence contradicts that assumption.
5.2 Decision under prompt §3 Stage 5
Prompt rule: "If V-1..V-7 PASS, COMMIT. If any FAIL, ROLLBACK." — V-3 FAIL ⇒ ROLLBACK. Orchestrator sent ROLLBACK; over the same psql session.
6. Stage 6 — Rollback verification (not Stage 6 post-COMMIT — no COMMIT occurred)
Rollback verified by independent read-only SELECTs against a fresh connection after the orchestrator closed the transaction session:
| Probe | Pre-R1 | Post-ROLLBACK | Verdict |
|---|---|---|---|
count(*) FROM information_unit |
12 | 12 | PASS — no IU residue |
count(*) FROM unit_version |
19 | 19 | PASS — no UV residue |
count(*) FROM birth_registry WHERE collection_name='information_unit' |
12 | 12 | PASS — no birth residue |
count(*) FROM tac_publication |
3 | 3 | PASS — TAC source unchanged |
count(*) FROM tac_logical_unit |
86 | 86 | PASS — TAC source unchanged |
count(*) FROM tac_unit_version |
86 | 86 | PASS — TAC source unchanged |
count(*) FROM tac_publication_member |
86 | 86 | PASS — TAC source unchanged |
Pre-existing 12 pilot/test IU rows: all UUIDs from preflight g10_existing_iu_ids still present (captured pre-list = post-list).
No exact-key DELETE was issued — the transaction's auto-rollback already discarded all writes. Exact-key rollback SQL was prepared as a skeleton in the rollback-keys KB doc but not executed (not needed; transactional ROLLBACK was sufficient).
rollback_performed=true, rollback_success=true (transactional rollback completed by ROLLBACK;).
7. Soft-flag report (per prompt §4)
| Row | canonical_address | body_char | Status |
|---|---|---|---|
| render_order=26 | D38-DIEU35-S8-P3 |
1 | RECORDED — was not repaired, inferred, expanded, normalized, or skipped. fn_iu_create accepted the 1-char body and produced a valid UV row (V-3a passed for this row inside the transaction). The row was rolled back along with the other 35. Semantic remediation, if any, is a separate content workflow. |
soft_flag_rows=[D38-DIEU35-S8-P3].
8. Hard-boundary compliance
| Boundary | Honored | Evidence |
|---|---|---|
| Exactly 36 IU rows created (then rolled back) | ✅ | loop_count=36, captured 36 IU + 36 UV UUIDs |
Birth via existing trg_birth_information_unit only |
✅ | 36 birth rows produced by the trigger; V-5 PASS during transaction |
fn_iu_create canonical writer only |
✅ | every IU/UV INSERT went through fn_iu_create (gateway-marker-checked) |
| No direct INSERT to IU/UV | ✅ | UPDATE patches used allowed marker fn_iu_apply_edit_draft; no direct INSERT path used |
| No DDL / schema / trigger / fn / birth-system changes | ✅ | none performed |
| No TAC writes | ✅ | V-6 PASS — TAC counts unchanged |
| No UI cutover / Nuxt / Directus / config changes | ✅ | none touched |
| No vector / Qdrant mutation / reindex | ✅ | none touched |
| No event_outbox / IU event emission work | ✅ | none performed |
| No bulk migration beyond DIEU-35 36 rows | ✅ | DIEU-28 (27) and DIEU-32 (23) untouched |
| Pre-existing 12 pilot/test IU rows untouched | ✅ | post-rollback verification: all 12 UUIDs present |
| No pattern-matching DELETE | ✅ | rollback used transactional ROLLBACK; only; exact-key skeleton not executed |
| Did not auto-fix source content anomaly (S8-P3 body_char=1) | ✅ | preserved verbatim during transaction; rolled back along with the rest |
9. Findings / recommendations for GPT/Opus review
| # | Finding | Recommendation |
|---|---|---|
| F-1 | TAC tac_unit_version.content_hash uses a different hashing scheme than fn_content_hash(body) (= sha256_hex(body)). Cross-system equality cannot hold without scheme harmonization. |
Decide: (a) Adapt V-3 spec so V-3b drops the cross-system equality requirement, replacing it with "TAC source body bytes preserved verbatim" (verified via direct text comparison or by re-deriving fn_content_hash(tac_unit_version.body) and confirming it equals the migrated UV content_hash). (b) Investigate TAC hash scheme and carry the original TAC hash through content_profile.src_content_hash as provenance only (already done by the R1 patch — content_profile.src_content_hash preserves the TAC value). (c) Defer R2 until V-3 spec is updated and re-run R1 once. |
| F-2 | V-3a is satisfied: 36/36 IU-side hash consistency. The migration design is sound at the IU layer. | Treat F-1 as a spec-clarification gap, not a migration defect. |
| F-3 | Rollback-key dual-write (KB + VPS log) worked correctly before rollback decision. | This validates the design §8 dual-write pattern for any future R1 retry. |
| F-4 | Transactional rollback was complete; zero residue. | No exact-key rollback was needed. |
| F-5 | Soft-flag S8-P3 (1-char body) was migrated verbatim inside the transaction and passed V-3a + V-5 + V-7. | Content fidelity at the byte level is preserved; future R1 may proceed once V-3 spec is updated. |
| F-6 | Rev2 of the rollback-keys KB doc was patched with a "ROLLBACK EXECUTED" note. | Keep both revisions as historical evidence. |
