1. Executive summary

deliverable: AD-4 artifact correction + isolated structural dry-run of the
  WS-Q5 registry-substrate DDL (12 cutter_governance tables) on an ephemeral
  local PostgreSQL cluster, with catalog-level verification + rollback test
input_ruling: GPT command-review PASS_FOR_ISOLATED_DRY_RUN_WITH_CONDITION
  (AD-1/2/3 APPROVED; AD-4 CONDITION_BEFORE_DRY_RUN -> corrected first)
dry_run_status: PASS
ad4_correction: DONE + recorded BEFORE execution (QG1)
production_executed: false
production_authorized: false
quality_gates: QG1–QG8 satisfied (§6)
verdict_requested_from: GPT / User

The AD-4 undercount (summary said 7 FK / 3 UNIQUE) was corrected to the canonical 8 FK / 4 UNIQUE and recorded before any SQL ran; executable table/constraint SQL was unchanged. The corrected DDL (sha256 1cf31237…) applied cleanly to an isolated ephemeral cluster (12 tables, rc=0, ~24ms); all catalog-level checks PASSed (12 tables / 12 PK / 8 schema-qualified FK / 4 UNIQUE / 0 CHECK / 0 trigger / 0 DEFAULT / 0 enum / 0 extra objects / all FK NO ACTION); the exact-inverse rollback (sha256 f4835326…, no CASCADE) ran rc=0 leaving 0 tables + 0 constraints. The environment was provably not production and was destroyed after the run.

2. AD-4 correction status

status: CLOSED
canonical_counts: foreign_keys=8, unique_constraints=4 (catalog-confirmed live)
executable_sql_changed: false (text/summary only)
recorded_before_dry_run: true (QG1)
disclosed_scaffold: "CREATE SCHEMA IF NOT EXISTS cutter_governance;" added for
  the empty cluster ONLY; production artifact must NOT create the schema (flagged)

3. Dry-run status

status: PASS
environment: isolated ephemeral local PG 14.17, socket-only (TCP refused),
  sysid 7641097877796842211 != prod 7611578671664259111, torn down + removed
ddl_apply: rc=0, 12 tables, ~0.0236s
verification: ALL PASS, fail_count=0 (catalog-level only)
rollback_test: rc=0, exact inverse, NO CASCADE, post-state clean (0/0), ~0.0177s
secrets: none recorded (trust-auth local socket; no credential)

4. Verification & rollback summary

verification: 14/14 checks PASS (TV/KC/CV/NH/AO/RB) — see verification-result file
  - AD-4 closure: catalog shows exactly 8 FK + 4 UNIQUE
  - KC-3: all 8 FK schema-qualified cutter_governance->cutter_governance
    (carries the C-07 / v0.3 false-negative lesson; no rendered-string compare)
rollback: exact inverse proven — 12 DROP TABLE reverse order, no CASCADE,
  0 tables + 0 constraints remaining; idempotent-clean teardown

5. Production readiness recommendation

ready_for_production_command_review: yes
  rationale: AD-4 closed; structural DDL + exact-inverse rollback + catalog
    verification all PASS on an isolated cluster; GPT rulings honored
production_authorized: NO — explicitly NOT authorized by this phase. Production
  apply requires a SEPARATE GPT/User sovereign command-review + approval.
required_before_production (residual — flagged, NOT done here):
  - R-1 dry-run / verification on a RESTORED PRODUCTION schema dump so the
    NG-1 (name collision vs the 12 existing prod tables) and NG-7 (no ALTER
    side-effect) negatives are actually exercised — needs VPS access (absent
    this session)
  - R-2 remove the disclosed dry-run scaffold line from the production artifact
    (schema cutter_governance already exists in prod)
  - R-3 separate downstream cycles still pending per prior rulings:
    AD-2 privilege/GRANT cycle, AD-3 DML seed cycle, then WS-VA vocab amend,
    WS-CK Cap-4 checker, WS-IX 7 indexes
recommended_smallest_next_step (advisory): GPT/User review this dry-run
  package; if PASS, schedule a restored-prod-schema dry-run (R-1) under its
  own command-review — NOT a direct production apply.

6. Quality gates

Gate	Requirement	Status
QG1	AD-4 correction recorded before dry-run	PASS — correction note pre-execution; sql_execution_before_correction:false
QG2	Dry-run env proven not production	PASS — distinct sysid, socket-only/no TCP, no prod credential, ephemeral
QG3	Verification catalog-level, no rendered-string equality	PASS — pg_catalog/information_schema only
QG4	If DDL fails, stop, no out-of-artifact schema fix	PASS — no FAIL occurred; no self-fix
QG5	Rollback no CASCADE + exact inverse	PASS — verified clean (0/0)
QG6	No secrets recorded	PASS — trust-auth local socket, none
QG7	Report states production still not authorized	PASS — §5 explicit
QG8	If no isolated env → BLOCKED, no prod substitute	PASS — isolated env was available & used; no production substitute

7. Risks / blockers

RK-1 fidelity: PG 14.17 vs prod PG 16 — LOW (only basic types/constraints used)
RK-2 not-restored-prod: collision/no-ALTER negatives untested (R-1) — MEDIUM,
  must be cleared in a restored-prod dry-run before production
RK-3 scaffold leakage: production artifact must drop the CREATE SCHEMA line
  (R-2) — LOW, explicitly flagged
blockers_for_production: R-1 (restored-prod dry-run, needs VPS access) +
  separate sovereign approval — production remains BLOCKED until then

8. Git / repo access note

repo_vps_access: NONE in this session
basis: cwd /Users/nmhuyen not a git repo (`git rev-parse` -> fatal); /opt/incomex
  absent. Local psql/initdb/pg_ctl present (PG 14.17) — used ONLY for the
  isolated ephemeral dry-run cluster (now destroyed). docker daemon unavailable.
branch / HEAD / `git status --short -- iu-cutter`: UNAVAILABLE (no repo access)
write_operations: none beyond KB doc upload; no git commit

9. Routing

status: WS_Q5_DDL_AD4_CORRECTED__ISOLATED_DRY_RUN_PASS__PRODUCTION_NOT_AUTHORIZED
package: 4 files uploaded to
  knowledge/dev/laws/dieu44-trien-khai/v0.5-ws-q5-registry-substrate-ddl-dryrun/
next_action: ROUTE TO GPT / USER — review dry-run; decide whether to open a
  restored-prod-schema dry-run / production command-review cycle (R-1) — NOT a
  direct production apply
agent_next: STOP — production NOT authorized; self-advance PROHIBITED

STOP. AD-4 corrected and recorded before execution; WS-Q5 registry-substrate DDL passed an isolated structural dry-run (apply + catalog verification + exact-inverse rollback) on an ephemeral, provably-non-production cluster that was destroyed afterward. No production SQL executed; production NOT authorized. Awaiting GPT/User review.
