Verdict

18c PASS. DOT-119 repair arc is complete.

trg_birth_information_unit has been installed via DOT-119 v2 and verified.

Evidence verified from actual report

• DOT-119 v2 behavior OK:
  • script md5 5883bce405b86ab436e885cf16fd22de
  • no CREATE OR REPLACE FUNCTION fn_birth_registry_auto
  • no KNOWN_V2_FN_HASH
  • --help prints v2.0.0
• IU metadata correct:
  • birth_code_strategy = synthetic_id
  • birth_code_column = NULL
  • birth_identity_source = manual
• Preflight clean:
  • IU rows = 0
  • existing IU trigger = 0
  • IU birth count = 0
• Dry-run OK:
  • strategy synthetic_id
  • args '__birth_synthetic_id__'
  • synthetic_capability = pass
• Execute OK:
  • CREATE TRIGGER via DOT-119
  • no raw CREATE by agent
• Verify OK:
  • status verified
  • function fn_birth_registry_auto
• Independent SQL OK:
  • exactly 1 trigger row
  • trigger definition includes '__birth_synthetic_id__'
• Invariants preserved:
  • function hash unchanged: 1f729b3571a74963089bb3ef388217f3
  • trigger count 30 → 31
  • IU birth count 0 → 0
  • IU rows 0 → 0
• Rollback not invoked.
• Hard boundaries honored.

Strategic conclusion

The original blocking issue for Pack 2B — IU data-row birth path — is now resolved at trigger-install level.

Next proof required: create controlled IU pilot rows and verify that INSERT fires fn_birth_registry_auto and writes birth_registry.entity_code = information_unit::<uuid> or the installed synthetic-shell format.

DOT-119 arc status

Completed:

1. P0 mapping report — PASS.
2. P1a schema tool inspection — PASS.
3. P1 metadata fields + seed + PG enforcement — PASS.
4. P2 DOT-119 v2 rewrite — PASS.
5. 18c IU trigger install — PASS.

Deferred TD:

• P3 health-check registration (H-BIRTH-IDENTITY-UNCLASSIFIED) remains useful but non-blocking.

Next directive to Opus/Ocus

Create the Pack 2B execution design/prompt, but do not dispatch yet.

Suggested file:

knowledge/dev/laws/dieu44-trien-khai/design/19-iu0-pack2b-pilot-crud-and-birth-fire-execution-pack.md

Or if Opus prefers prompt-first:

knowledge/dev/laws/dieu44-trien-khai/prompts/19-iu0-pack2b-pilot-crud-and-birth-fire-prompt.md

Pack 2B goal

Create a very small number of controlled IU pilot rows to prove:

1. IU insert works under existing L1/L2 gates.
2. trg_birth_information_unit fires.
3. birth_registry receives correct synthetic entity code.
4. unit_version behavior works as subordinate/no independent birth.
5. No unintended rows, triggers, function edits, or governance drift occur.

Recommended Pack 2B scope

Use 1–2 pilot IU rows only, under a clear pilot namespace such as:

• pilot.iu0.overview
• pilot.iu0.description_policy

But Opus must verify the exact required IU schema before writing any INSERT.

Pack 2B preflight requirements

• read IU schema/design docs;
• inspect actual information_unit and unit_version columns;
• inspect constraints/triggers on both tables;
• confirm IU row count = 0 before pilot;
• confirm trg_birth_information_unit exists and verified;
• capture function hash baseline;
• capture IU-specific birth count baseline;
• capture total birth count as audit only.

Pack 2B execution principle

No hardcode beyond approved pilot payload values.

Do not invent required columns from memory. Agent must inspect actual schema first, then build exact INSERT payloads.

Pack 2B post-verify

• IU row count increases by expected number.
• IU birth count increases by expected number.
• Birth entity_code format is synthetic-shell from actual trigger/function output.
• No unit_version independent birth unless explicitly designed.
• Function hash unchanged.
• Trigger count unchanged.
• Rollback/cleanup decision must be explicit: keep pilot rows or soft-delete/archive.

Hard boundaries

• no raw trigger/function work;
• no schema changes;
• no DOT-119 rewrite;
• no Pack 2C/vector/outbox/Qdrant;
• no Directus exposure unless separately approved;
• no P3/HC in this pack.

Current state

Ready for Pack 2B design. Do not jump straight into CRUD execution without schema-first prompt, because IU payload requirements must be derived from actual DB schema and design docs, not guessed.
