Date: 2026-05-16
Reviewer: GPT
Files reviewed: P0-2 DDL draft, verification plan, rollback draft, risk note, authoring report
Scope: DDL authoring review only. No DDL executed, no mutation, no dry-run, no production action.

1. Verdict

p0_2_ddl_authoring_status: PASS
agent_revision_needed: false
risk_class: STANDARD
DDL_authoring_package_accepted: true
P0_2_dry_run_allowed_after_explicit_prompt: true
production_migration_allowed: false

The P0-2 DDL authoring package is accepted. The next gate is dry-run only.

2. Accepted DDL Shape

schema: cutter_governance
new_tables:
  - manifest_envelope
  - manifest_unit_block
manifest_envelope_columns: 12
manifest_unit_block_columns: 14
pg_foreign_keys:
  - manifest_unit_block.envelope_id_to_manifest_envelope.envelope_id
cross_schema_FK: 0
CHECK_constraints: 0
triggers: 0
DEFAULT_clauses: 0
alias_ref_column: false
edge_tables: false
INSERTs: 0
transaction: single_BEGIN_COMMIT

The only accepted PostgreSQL FK is the in-schema child-to-parent FK.

3. Decision on No DEFAULT

GPT accepts 0 DEFAULT in P0-2.

Rationale:

• Tables are created empty.
• There is no writer in P0-2.
• Defaults would only affect future inserts, which belong to the P1 writer layer.
• Avoiding defaults keeps P0-2 structural and prevents premature policy binding.
• This follows the binding constraint: no PG CHECK / trigger / DEFAULT in P0-2.

no_DEFAULT_status: accepted
future_default_policy_owner: P1_writer_layer

4. GOV Decisions Encoding Accepted

GOV_1_O3_hybrid:
  encoded_by: proposed_canonical_address_column
  enforcement: P1_logic

GOV_2_O1_demote_to_draft:
  encoded_by: proposed_authority_column
  enforcement: P1_writer_review_logic

GOV_3_O1_event_backed_no_coupling:
  encoded_by: absence_of_alias_ref_column
  enforcement: P1_event_backed_alias_emission

---

5. Verification and Rollback Accepted

verification_checks: 20
rollback_order:
  - drop_manifest_unit_block
  - drop_manifest_envelope
rollback_data_loss_expected: none_if_tables_empty
post_commit_rollback_requires_explicit_prompt: true

Dry-run must prove all 20 checks and table row counts = 0.

6. Next Gate

ready_for_P0_2_dry_run_prompt: true
ready_for_production_prompt: false

Agent may execute P0-2 DDL only in an isolated dry-run environment after explicit prompt. Production remains forbidden.
