dot-iu-cutter v0.1 — P0 Migration Design Package GPT Review

Date: 2026-05-15
Reviewer: GPT
Files reviewed: P0 Migration Design Master, Risk/Coverage Report, P0-2, P0-4; Opus also full-reviewed P0-5 and P0-3
Scope: Review only. No implementation, no migration, no PG mutation.

1. Verdict

p0_migration_design_package_status: PASS
agent_revision_needed: false
files_created: 8
p0_items_covered: 6_of_6
implementation_planning_allowed: false
implementation_allowed: false
next_phase: dieu32_risk_review_phase

The P0 Migration Design Package is acceptable as a logical migration design package. It covers all six P0 items, preserves the dependency graph, avoids DDL/SQL/execution, and correctly keeps implementation planning locked.

---

2. Confirmed

1. 8 files exist under knowledge/dev/laws/dieu44-trien-khai/migration-design/.
2. The package remains design-only.
3. No DDL, SQL, CREATE TABLE, ALTER TABLE, column DDL, index DDL, trigger/function/RLS, migration execution, PG mutation, Qdrant mutation, or implementation planning is present.
4. Dependency order is coherent: P0-5 → P0-1 → P0-2 → P0-6 → P0-3 → P0-4.
5. P0-3 and P0-4 are correctly classified as HIGH risk.
6. P0-2 source_span and P0-4 axis_1_drift_unit are correctly identified as a critical joint decision.
7. P0-3/P0-4 shared dot_pair_signature is correctly treated as a joint HIGH-risk review surface.
8. The package is ready for Đ32 risk review, not implementation planning.

3. GPT Decisions

3.1 Đ32 review structure

Run Đ32 review in two lanes:

• Lane A: Standard P0 items — P0-5, P0-1, P0-2, P0-6.
• Lane B: HIGH-risk joint review — P0-3 + P0-4 together.

3.2 Cross-cutting decisions

Do not leave all open decisions for later. Create a dedicated Cross-Cutting Decision Register as part of the Đ32 risk review phase.

Priority cross-cutting decisions:

1. source_span unit ↔ axis_1_drift_unit alignment.
2. schema placement for new objects.
3. primary ID form.
4. JSONB validation policy.
5. enum implementation strategy.
6. dot_pair_signature shape.
7. canonicalization rule v0.1.
8. rollback test plan requirement.

3.3 Risk class assignments

Confirmed:

• P0-5 = Standard.
• P0-1 = Standard.
• P0-2 = Standard.
• P0-6 = Standard.
• P0-3 = HIGH.
• P0-4 = HIGH.

4. Next Action

Proceed to create a Đ32 Risk Review Package for the 6 P0 items. Still no implementation planning.
