dot-iu-cutter v0.1 — P0 Implementation Planning Package GPT Review

Date: 2026-05-15
Reviewer: GPT
Files reviewed: P0 Implementation Planning Report and Cross-Cutting Resolution Plan metadata/snippet directly; Opus full-reviewed the two summary files
Scope: Review only. No code, no DDL, no SQL, no migration, no PG mutation.

1. Verdict

implementation_planning_package_status: PASS
agent_revision_needed: false
implementation_planning_phase: complete_pending_final_readiness_review
implementation_execution_allowed: false
next_phase: final_execution_readiness_review

The Implementation Planning Package is acceptable. It resolves or plans the seven carried cross-cutting decisions, preserves the P0 sequence, authors rollback/canonicalization/preflight planning, and keeps execution locked.

---

2. Confirmed Decisions

X_1_schema_placement: cutter_governance schema class; P0-1 remains in TAC
X_2_primary_id_form: uuid with human aliases
X_3_JSONB_validation: application-layer v0.1; PG jsonb_check future
X_4_enum_strategy: Đ24 lookup FK
X_6_dot_pair_signature_shape: shared table + revocation lifecycle + exactly-one cross-reference
X_7_canonicalization_rule: prose authored for Đ24 ratification before execution
X_8_rollback_test_plan: 26-scenario matrix authored; dry-run required before execution

GPT accepts these selected approaches for planning purposes.

3. Execution Gate Status

implementation_execution_allowed: false
execution_gate_next_step: Final Execution Readiness Review

Execution remains blocked until the Final Execution Readiness Review confirms that all execution blockers are closed and User/GPT explicitly authorizes execution.

---

4. Required Final Readiness Inputs

The Final Execution Readiness Review must verify:

1. Đ44 + Đ33/Đ43 sign-off for X-1 schema placement.
2. Đ24 ratification / lookup readiness for X-4 enum strategy.
3. G-4 + Đ44 sign-off for X-6 dot_pair_signature shape.
4. Đ24 ratification of X-7 canonicalization prose.
5. Đ32 + G-4 sign-off that X-8 rollback test plan is ready, with dry-run explicitly required before real execution.
6. Operational seat naming for required governance seats, at minimum G-2 and G-4, and G-5 if access-control surfaces are touched.
7. DOT-pair registration plan: executor + verifier.
8. Backup/snapshot/preflight plan is ready.
9. Migration execution remains unstarted.

5. Status

ready_to_prompt_final_execution_readiness_review: true
ready_for_implementation_execution: false
agent_revision_needed: false
