Files SSOT cho phiên mới

1. design/19-iu0-pack2b-pilot-crud-and-birth-fire-execution-pack.md — Pack 2B design
2. reports/iu-birth-trigger-install-18c-report.md — 18c report
3. reports/dot119-repair-p2-script-rewrite-report.md — P2 report
4. reports/dot119-repair-p1-metadata-ddl-seed-report.md — P1 report
5. reviews/gpt-review-18c-report-and-pack2b-directive-2026-05-05.md — GPT Pack 2B directive

Phiên mới cần làm

1. Đọc Pack 2B design (file 19) + GPT directive
2. Tạo P2B-P0 prompt: schema inspection read-only
3. Dispatch → report → review
4. Tạo P2B-P1 prompt: pilot INSERT (schema-first, exact payloads)
5. Dispatch → verify birth fire → report

Bài học phiên này

• Anti-hardcode: row count bảng sống = run-local baseline, không literal từ phiên trước
• Anti-hardcode: fn hash dùng audit (before/after), không gate bằng literal
• Anti-hardcode: capability check thay exact hash
• Inspect trước spec: DOT-063 cần meta.readonly — inspect field template trước
• Smoke fail → rollback: core tool phải restore v1 nếu test fail
• Phản biện GPT: khi GPT chỉ đạo hardcode, Opus PHẢI phản biện theo HP §0-AU
