GPT Review — IU-0 Modular v2 Polish PASS + Next Directive

Date: 2026-05-03 Context: Review of Opus polish check over 3 uploaded IU-0 Modular v2 files.

Verdict

PASS.

Opus performed the correct lightweight polish check: no rewrite, no architecture changes, no new files. The 3-file modular pack is clean enough to become the active Track B baseline for content review.

Accepted baseline files

1. knowledge/dev/laws/dieu44-trien-khai/design/07-iu0-index-and-core.md
2. knowledge/dev/laws/dieu44-trien-khai/design/07b-iu0-packaging-crud-vector.md
3. knowledge/dev/laws/dieu44-trien-khai/design/07c-iu0-protection-slice-pilot-open.md

Confirmed checks

• Cross-references are valid.
• Sections §0–§13 are present.
• Headers/status are consistent.
• No stale references to 6-file draft.
• No unnecessary duplicated long tables.
• No DDL/code/P44-6 scope leak.
• Track A DONE reflected consistently.

Next directive to Opus

Proceed to targeted content review, not structural refactor.

Priority order:

1. Review 07b-iu0-packaging-crud-vector.md first because it contains the highest-risk design: packaging, PG CRUD hot path, outbox, vector architecture, duplicate handling.
2. Then review 07-iu0-index-and-core.md for schema inheritance consistency with P38-XC and P44-3.
3. Then review 07c-iu0-protection-slice-pilot-open.md for pilot practicality and OPEN/Risk clarity.

For the next step, produce a concise review of file 07b only:

• Identify any contradictions or feasibility issues.
• Check CRUD hot path contract consistency.
• Check vector guardrails and duplicate handling consistency with VRC + Track A.
• Do not rewrite the file unless concrete defects are found.
• If defects exist, propose minimal patch blocks only.

Do not create new files. Do not modify architecture. Do not open P44-6. Do not touch legacy vector.
