P3D — Birth B3-P Policy Population — Execution Report

Date: 2026-05-12 Prompt: knowledge/dev/laws/dieu44-trien-khai/prompts/p3d-birth-b3p-policy-population-prompt-DRAFT.md (rev2) Approved artifact: knowledge/dev/laws/dieu44-trien-khai/reports/p3d-birth-coverage-classification-report.md (revision 1, verified) Status: PASS

Resolved scope

host = 38.242.240.89
container = postgres
database = directus
schema = public
table = collection_registry
actor = b3p_policy_population

Phase 0 — Prerequisites

  • 6 coverage_* columns present on public.collection_registry (verified — added by B3-P DDL).
  • All 6 columns and 2 CHECK constraints carried over from DDL execution report.
  • Approved classification artifact revision = 1 ⇒ matches expected ⇒ approved_artifact_revision_verified=true.

Phase 1 — Loaded classification (no hardcoded counts; derived live from artifact)

Status (artifact) Derived count
BIRTH_REQUIRED 43
EXEMPT_JUNCTION 20
EXEMPT_LOG 11
EXEMPT_CACHE 4
DEFERRED missing_table 7
DEFERRED special_case 3
DEFERRED excluded_CMS 31
DEFERRED excluded_AgencyOS 17
artifact_total 136

Existing-trigger collections (live information_schema.triggers query):

existing_trigger_collections (in registry) = 30
existing_trigger_collections (not in registry) = 0

Combined population map size = 136 + 30 = 166, equal to count(*) public.collection_registry. No UNCLASSIFIED_NEW.

Phase 2 — Population map

Built as a temp table inside the transaction (pop_map). Sources:

  1. Per-collection mapping from approved classification report.
  2. Live trigger query: collections already wired ⇒ BIRTH_REQUIRED + IN_SCOPE.

Mapping rules applied (rev2 design §5):

Source bucket coverage_status coverage_scope_status reason review_owner
existing trigger BIRTH_REQUIRED IN_SCOPE — —
BIRTH_REQUIRED BIRTH_REQUIRED IN_SCOPE — —
EXEMPT_JUNCTION BIRTH_EXEMPT_STRUCTURAL_JUNCTION IN_SCOPE Junction text —
EXEMPT_LOG BIRTH_EXEMPT_SYSTEM_LOG_OR_AUDIT IN_SCOPE Log/audit text —
EXEMPT_CACHE BIRTH_EXEMPT_DERIVED_CACHE IN_SCOPE Derived/view —
DEFERRED missing_table BIRTH_DEFERRED_NEEDS_REVIEW ORPHAN_REGISTRY Registry row without physical table registry_cleanup_team
DEFERRED special_case BIRTH_DEFERRED_NEEDS_REVIEW IN_SCOPE Per-case note governance_council
DEFERRED excluded_CMS BIRTH_DEFERRED_NEEDS_REVIEW USER_EXCLUDED CMS (user-excluded) cms_team
DEFERRED excluded_AgencyOS BIRTH_DEFERRED_NEEDS_REVIEW FUTURE_SCOPE Agency OS future scope agencyos_team

Phase 3 — Old values snapshot

Captured in-transaction into temp old_values_snapshot before UPDATE. All 166 rows had every coverage_* column = NULL (the post-DDL pre-population state). old_values_captured = true.

Phase 4 — Execution log + compiled preview

RUN_STARTED_AT = 2026-05-12T09:06:17Z
RUN_ENDED_AT   = 2026-05-12T09:06:17Z
LOG_FILE       = /var/log/incomex/p3d/p3d-birth-b3p-population-20260512T090612Z.log
HOST           = 38.242.240.89
compiled_sql_logged = true

Compiled SQL (excerpt — full SQL persisted to /tmp/p3d-b3p-pop.sql on VPS + executed verbatim):

BEGIN;
SELECT pg_try_advisory_xact_lock(hashtext('p3d_birth_b3p_policy_population'));

CREATE TEMP TABLE pop_map (...) ON COMMIT DROP;
INSERT INTO pop_map ... (43 BIRTH_REQUIRED rows)
INSERT INTO pop_map ... (20 EXEMPT_JUNCTION rows)
INSERT INTO pop_map ... (11 EXEMPT_LOG rows)
INSERT INTO pop_map ... (4 EXEMPT_CACHE rows)
INSERT INTO pop_map ... (7 ORPHAN_REGISTRY rows)
INSERT INTO pop_map ... (3 special_case rows)
INSERT INTO pop_map ... (31 USER_EXCLUDED CMS rows)
INSERT INTO pop_map ... (17 FUTURE_SCOPE AgencyOS rows)
INSERT INTO pop_map SELECT FROM information_schema.triggers ... ON CONFLICT DO NOTHING;
  -> +30 existing-trigger rows merged

CREATE TEMP TABLE old_values_snapshot AS SELECT ... FROM public.collection_registry;

-- UNCLASSIFIED gate
DO $$ ... RAISE EXCEPTION IF unclassified > 0 $$;

UPDATE public.collection_registry cr
SET coverage_status            = pm.coverage_status,
    coverage_scope_status      = pm.coverage_scope_status,
    coverage_exemption_reason  = pm.coverage_exemption_reason,
    coverage_review_owner      = pm.coverage_review_owner,
    coverage_decided_at        = now(),
    coverage_decided_by        = 'b3p_policy_population'
FROM pop_map pm
WHERE cr.collection_name = pm.collection_name
  AND cr.coverage_status IS NULL;

-- Post-UPDATE null-check gate
DO $$ ... RAISE EXCEPTION IF null_coverage_status > 0 $$;

COMMIT;

Phase 5 — Transaction outcome

psql exit_code = 0
advisory_lock_acquired = true
UPDATE rows affected = 166
unclassified_new = 0
null_coverage_remaining = 0
COMMIT = success

Phase 6 — Post-commit distribution

 coverage_status                  | coverage_scope_status | count
----------------------------------+-----------------------+------
 BIRTH_DEFERRED_NEEDS_REVIEW      | FUTURE_SCOPE          |    17
 BIRTH_DEFERRED_NEEDS_REVIEW      | IN_SCOPE              |     3
 BIRTH_DEFERRED_NEEDS_REVIEW      | ORPHAN_REGISTRY       |     7
 BIRTH_DEFERRED_NEEDS_REVIEW      | USER_EXCLUDED         |    31
 BIRTH_EXEMPT_DERIVED_CACHE       | IN_SCOPE              |     4
 BIRTH_EXEMPT_STRUCTURAL_JUNCTION | IN_SCOPE              |    20
 BIRTH_EXEMPT_SYSTEM_LOG_OR_AUDIT | IN_SCOPE              |    11
 BIRTH_REQUIRED                   | IN_SCOPE              |    73

Cross-check vs map:

  • BIRTH_REQUIRED 73 = 43 (artifact) + 30 (existing triggers) ✓
  • Exempt total 35 = 4 + 20 + 11 ✓
  • Deferred total 58 = 17 + 3 + 7 + 31 ✓
  • Grand total 166 ✓

Phase 7 — Rollback SQL (logged)

Per-row restore from old_values_snapshot — since pre-population values were all NULL (DDL just created the columns), the semantically equivalent per-row restore is:

UPDATE public.collection_registry
SET coverage_status = NULL,
    coverage_scope_status = NULL,
    coverage_exemption_reason = NULL,
    coverage_review_owner = NULL,
    coverage_decided_at = NULL,
    coverage_decided_by = NULL
WHERE coverage_decided_by = 'b3p_policy_population';

The WHERE coverage_decided_by = 'b3p_policy_population' predicate scopes the rollback strictly to rows this population wrote, so future manual overrides are preserved.
