GPT Review — P7A Step 4–9 Checkpoint B

Verdict

PASS-WITH-MINOR. P7A Step 4–9 đạt mục tiêu dry-run staging: 76 units, 3 proposed publications, label mapping proposal, simulated checker report, round-trip comparison, component candidate log. Không có production write, không DDL/SQL, không sửa source. Không phát hiện xung đột với P7 v0.2, C1A, P5, Đ24, Đ32, Đ33.

Notes

1. SHA-256 pending là acceptable trong Desktop dry-run, nhưng phải tính thật ở P7B/P8 bằng agent/runtime có hash tool.
2. content_hash placeholder/pending acceptable ở staging, nhưng không được coi là PASS production birth gate.
3. Block-count delta cần đổi metric: intentional merge vs unintentional loss. Unintentional loss = 0 nên PASS.
4. “11 artifacts in one report” acceptable cho P7A review artifact; P7B/P8 nên xuất file riêng nếu agent execution.
5. Đ24 facets/entity_code chưa verify; không blocker cho P7A, là blocker trước implementation.

Checkpoint B Decisions

• 76 units: acceptable.
• Merge strategy: acceptable with intentional merge tracking.
• Block delta metric: amend in pilot notes; do not block.
• 7 soft-limit units: accept; semantic coherence > mechanical split.
• 5 component candidates: defer to round 2.
• Go/No-go: GO to P7B sandbox PG prototype design.

Instruction

Opus should not upload staging artifacts as official KB law/design documents. Next step is P7B: design and, after user approval, coordinate sandbox PG prototype only. P7B must define sandbox boundary, collections/tables to create, read/write permissions, no-production-change guard, seed data plan from P7A staging, and verification/rollback plan. No production migration.
