dot-iu-cutter v0.2 — P0-6 + P0-5 Remainder Production Execution Report

document_path: knowledge/dev/laws/dieu44-trien-khai/v0.2-execution/dot-iu-cutter-v0.2-p0-6-p0-5-remainder-production-execution-report-2026-05-16.md
revision: r1
date: 2026-05-16
author: Agent (Claude Code CLI, Opus 4.7 1M)
sovereign: User / anh Huyên
verifier: GPT (PENDING)
phase: v0.2 — P0-6 + P0-5-remainder PRODUCTION EXECUTION
execution_status: rolled_back
root_cause: verification-harness false-negative (NOT a DDL fault)
production_state: UNCHANGED (restored to pre-migration 8-table baseline; zero data loss)
v0_2_structural_schema_complete: false
ddl_revision_used: r2 (sha 89652d5f…c4b0; r1 NOT used)

⚠️ execution_status = ROLLED_BACK. C-06 migration executed successfully and created the correct 4 tables + 7 FKs, but the C-07 harness raised a false-negative on 7 FK-shape string assertions (expected strings omitted the cutter_governance. schema qualifier that pg_get_constraintdef() emits). Per the conservative C-07-fail rule, C-08 rollback ran and cleanly restored production to the original 8-table state. Honest disclosure: this is an Agent verification-script defect, not a DDL or process defect. No self-advance; awaiting GPT review.

§1 — Execution Status

execution_status: rolled_back
why: C-07 verification reported FAIL due solely to 7 FK-shape EXPECTED-string
     assertions missing the schema qualifier; this tripped the conservative
     "C-07 fail → C-08 rollback (tables empty ⇒ safe)" gate.
ddl_itself: executed successfully (C-06 rc=0; 4 tables + 7 correct FKs created)
production_after: pre-migration baseline (8 cutter_governance tables); SAFE
data_loss: NONE (tables were created empty; rollback dropped empty tables)

§5 — C-06 Migration Result & C-07 Verification

C-06 — SUCCESS

psql -v ON_ERROR_STOP=1 -f - on prod postgres/directus: BEGIN / CREATE TABLE ×4 / COMMIT, C06_RC=0. The 4 tables + 7 FKs were created.

C-07 — substantive checks ALL PASS; 7 FK-shape assertions FALSE-NEGATIVE

PASSED (genuine): cg_count=12; 4 tables exist; all 4 rows=0;
  colcounts review=25/history=9/dependency=6/sweep_log=10; fk_count=7;
  cross_schema_fk=0; check=0; trigger=0; default=0; pg_enum=0; lookup=0;
  forbidden_child_cols=0; entry_family_cols=1/2; seed_rows=0;
  dbe_pk_after=entry_id uuid; me_pk/mub_pk unchanged; me/mub rows=0;
  alias=t; tac=86; sandbox=76; v01_present=5
FK shapes (post) observed — ALL 7 CORRECT (identical to PASS_WITH_NOTES dry-run):
  decision_backlog_history_entry_fk    : (entry_id) → cutter_governance.decision_backlog_entry(entry_id)
  decision_backlog_dependency_from_fk  : (from_entry_id) → cutter_governance.decision_backlog_entry(entry_id)
  decision_backlog_dependency_to_fk    : (to_entry_id) → cutter_governance.decision_backlog_entry(entry_id)
  review_decision_manifest_fk          : (manifest_id) → cutter_governance.manifest_envelope(envelope_id)
  review_decision_unit_block_fk        : (manifest_id, manifest_unit_local_id) → cutter_governance.manifest_unit_block(envelope_id, unit_local_id)
  review_decision_prior_fk             : (prior_review_decision_id) → cutter_governance.review_decision(review_decision_id)
  review_decision_superseded_fk        : (superseded_by_review_decision_id) → cutter_governance.review_decision(review_decision_id)
FALSE-NEGATIVE (harness bug): the 7 explicit chk fk_* assertions compared
  pg_get_constraintdef() output against EXPECTED strings that OMITTED the
  "cutter_governance." schema qualifier. Actual emits e.g.
  "...REFERENCES cutter_governance.decision_backlog_entry(entry_id)";
  expected was "...REFERENCES decision_backlog_entry(entry_id)" → string
  mismatch → 7× VFAIL → C07_RESULT=FAIL.
assessment: NOT a DDL/schema fault. The objects are provably correct (FK-shapes
  table + every substantive check + byte-identical artefact to the GPT-PASSed
  PASS_WITH_NOTES dry-run). The fault is in the Agent's C-07 string assertion.

§6 — Created Objects (then rolled back)

Created by C-06, then dropped by C-08 (production currently has none of these): cutter_governance.review_decision, …decision_backlog_history, …decision_backlog_dependency, …decision_backlog_sweep_log + their 4 PKs + 7 in-schema FKs. Net production: these objects do NOT exist.

§7 — Rollback Status (C-08)

trigger: C-07 reported FAIL (false-negative §5) → conservative C-08 gate
safety_check: new tables non-empty? 0 → SAFE to drop
executed: BEGIN / DROP TABLE ×4 (sweep_log,dependency,history,review_decision) / COMMIT
C08_RC: 0
no_CASCADE: TRUE (plain DROP TABLE)
live_parents_dropped: NONE
cg_count_after_rollback: 8
independent_readonly_post_confirm:
  cg_count=8 ; new4_present=0 ; decision_backlog_entry PK=entry_id uuid ;
  manifest_envelope rows=0 ; manifest_unit_block rows=0 ;
  public.tac_logical_unit=86 ; sandbox_tac.logical_unit=76 ;
  PROD_SYSID=7611578671664259111 (unchanged) ;
  POST_cg_list = canonical_address_alias, cut_change_set,
    cut_change_set_affected_row, decision_backlog_entry, dot_pair_signature,
    manifest_envelope, manifest_unit_block, verify_result  (exactly the original 8)
result: clean rollback; production restored to pre-migration baseline; no data loss

§8 — Non-Scope Confirmation (nothing forbidden performed)

no_INSERT / no_seed / no_backfill: TRUE (seed_rows_total=0 while tables existed)
no_r1_DDL_used: TRUE (r2 only, sha 89652d5f…c4b0)

no_P0_2_manifest_change: TRUE (PKs unchanged; 0 rows; not altered)
no_phase_alpha_change: TRUE (canonical_address_alias present, untouched)
no_v0_1_change: TRUE (5 v0.1 tables intact; decision_backlog_entry PK=entry_id uuid unchanged)
no_public_tac_logical_unit_change: TRUE (86 → 86)
no_sandbox_tac_logical_unit_change: TRUE (76 → 76)
no_cross_schema_FK / no_CHECK / no_trigger / no_DEFAULT / no_PG_enum / no_lookup_table: TRUE
no_SQL_outside_C01..C07_except_C08_rollback: TRUE (C-08 was the authorized conditional path)
production_CUT_run: NO
production_VERIFY_run: NO
qdrant_vector_touched: NO
deploy_performed: NO
scope_self_expanded: NO

execution_status: rolled_back
v0_2_structural_schema_complete: FALSE  (the 4 tables are NOT in production)
production_state: SAFE — identical to pre-migration (8 tables); zero data loss;
  identity unchanged; backup retained + integrity reconfirmed
defect_owner: Agent C-07 verification harness (FK-shape expected strings missing
  "cutter_governance." schema qualifier). DDL artefact + process are sound.
next_recommended_step: |
  GPT review of this report. Recommended remediation (NOT performed; requires
  explicit re-authorization — Agent does NOT self-advance):
    1. Correct the C-07 FK-shape assertions to schema-qualified expected
       values (or compare child/parent/columns structurally instead of the
       full pg_get_constraintdef string). DDL artefact UNCHANGED (r2, sha
       89652d5f…c4b0 — already GPT-PASSed + dry-run-proven).
    2. Re-authorize a single re-execution of C-01..C-07 with the corrected
       harness. (This is a "further migration" → forbidden without explicit
       GPT/User authorization.)
  No re-run, no CUT/VERIFY, no integration, no further migration performed.
agent_self_advance: PROHIBITED — awaiting GPT review.
