Reviewed report: knowledge/dev/laws/dieu44-trien-khai/v0.4-credential-execution/dot-iu-cutter-v0.4-production-credential-execution-report-2026-05-17.md
Scope: Production credential execution review. No runtime adapter / CUT / VERIFY authorization.

1. Verdict

v0_4_production_credential_execution: PASS
execution_status: SUCCESS_LIVE
script_fail_label: accepted_as_harness_false_negative
rollback_required: false
agent_revision_needed: false
credentials_live: true
runtime_use_allowed: false
real_DB_adapter_design_may_open: true
CUT_VERIFY_allowed: false
deploy_allowed: false

GPT accepts the execution report. cutter_exec and cutter_verify are live in production with the accepted least-privilege matrix.

2. Accepted Evidence

roles_created:
  - cutter_exec
  - cutter_verify
role_flags:
  LOGIN: true
  CONNECTION_LIMIT: 2
  NOSUPERUSER: true
  NOCREATEDB: true
  NOCREATEROLE: true
  NOREPLICATION: true
  NOBYPASSRLS: true
memberless: true
object_ownership: 0
password_storage: SCRAM_SHA_256

privileges_verified:
  table_privilege_tuples: 33
  column_update_tuples: 3
  exact_matrix_match: true
  grant_option: 0
  destructive_privileges: 0
  out_of_schema_privileges: 0
  cutter_ro_unchanged: true
  Directus_unchanged: true
  RLS_unchanged: true

3. Harness False-Negative Ruling

The script label FAIL / ABORTED_NO_APPLY is accepted as a harness false-negative, not a production failure.

root_cause: grep_c_zero_match_exit_1_appended_second_zero
location: post_hoc_G09_disk_hygiene_self_check
substantive_SQL_apply: true
SQL_apply_rc: 0
verification_passed: true
independent_reverification_passed: true
secret_hygiene_proven_clean: true
rerun_required: false
rollback_required: false

Reasoning: the accepted credential SQL committed, all structural and behavioral checks passed, and independent read-only re-verification confirmed the exact matrix and no leak. Re-running would be inappropriate because the precondition roles absent is no longer true.

6. Gate Effect

production_credentials: LIVE_PASS
real_DB_adapter_design: may_open_after_explicit_prompt
real_DB_adapter_code: still_blocked_until_design_PASS
runtime_binding_to_credentials: still_blocked
PG_backed_dry_run: still_blocked
production_CUT_VERIFY: still_blocked

---

7. Next Recommended Cycle

Next phase should be:

phase: v0_4_real_DB_adapter_design
nature: design_only
reason:
  - credentials now exist
  - in-memory cutter-agent code is already PASS
  - runtime code must not use credentials until adapter design and test plan are reviewed

This next design must cover connection handling, credential loading without printing secrets, transaction mapping, privilege-safe probes, dry-run-only first use, and adapter rollback/failure semantics. No code or production connection should happen in that design phase.

8. Status

credentials_review_closed: PASS
ready_for_real_DB_adapter_design_prompt: true
agent_self_advance: prohibited_without_explicit_prompt
