dot-iu-cutter v0.2 — P0-6 + P0-5 Remainder A-1 HALT GPT Review

Date: 2026-05-16
Reviewer: GPT
Files reviewed: dry-run execution report, verification results, artefact index
Scope: HALT review and re-revision direction. No DDL, no mutation, no dry-run execution.

1. Verdict

dry_run_halt_status: CORRECT_HALT
agent_behavior: PASS
root_cause: production_schema_mismatch_vs_design_assumption
DDL_revision_required: true
production_touched: false
dry_run_env_created: false
production_migration_allowed: false

Agent behaved correctly. A-1 was designed to catch exactly this class of mismatch and it did.

2. Confirmed Schema Truth

live_table: cutter_governance.decision_backlog_entry
actual_primary_key:
  column: entry_id
  type: uuid
design_assumption_that_failed:
  column: decision_id
  type: uuid
decision_id_exists: false

The type assumption was correct (uuid), but the column name was wrong. This is a design-to-production drift from the earlier v0.1 design documents.

3. Binding Fix Direction

GPT selects the consistent naming fix:

fix_strategy: rename_child_columns_to_entry_id_family
not_selected: keep_child_column_names_as_decision_id_and_only_change_FK_target
reason: align_child_tables_with_live_parent_schema_and_reduce_future_terminology_debt

Required DDL r2 changes:

decision_backlog_history:
  old_column: decision_id
  new_column: entry_id
  FK_target: decision_backlog_entry.entry_id

decision_backlog_dependency:
  old_columns:
    - from_decision_id
    - to_decision_id
  new_columns:
    - from_entry_id
    - to_entry_id
  FK_targets:
    - decision_backlog_entry.entry_id
    - decision_backlog_entry.entry_id

All other ratified design decisions remain unchanged.

4. DDL Authoring Revision Required

Agent must produce r2 authoring package, not execute it.

required_updated_files:
  - ddl_draft_r2
  - verification_plan_r2
  - rollback_draft_r2_if_references_column_names
  - risk_review_note_r2_if_needed
  - ddl_authoring_report_r2

The r2 package must explicitly state:

A_1_status: resolved_by_r2
FK_count_expected: 7
cross_schema_FK: 0
CHECK: 0
trigger: 0
DEFAULT: 0
production_execution_allowed: false
dry_run_allowed_after_GPT_r2_review: true

---

5. Gate Effect

current_dry_run_status: HALTED_NOT_PASS
r1_DDL_status: superseded_do_not_execute
r2_authoring_allowed: true_after_explicit_prompt
r2_dry_run_allowed_now: false
production_allowed: false

No workaround is allowed. The DDL must be revised and re-reviewed before dry-run resumes.
