GPT Review — IU-0 07c Independent PASS; Modular Baseline Active

Date: 2026-05-03 Context: Independent check of Opus review for 07c-iu0-protection-slice-pilot-open.md.

Method

GPT independently read knowledge/dev/laws/dieu44-trien-khai/design/07c-iu0-protection-slice-pilot-open.md from Agent Data after receiving Opus's report.

Verdict

PASS.

No patch needed for 07c.

Independent findings

1. Protection guardrails

PASS.

• G-1..9 are schema/protection guardrails.
• VG-1..9 are vector-specific and are correctly referenced from 07b §6.8.
• G-4 (Vector = projection) aligns with VG-9 (PG/KB = SSOT; vector = projection).
• G-6 (2-layer separation) aligns with VG-1/VG-7: do not mutate or overload production_documents.
• No conflict with GR-1..10 in the index file.

2. Slice editing workflow

PASS.

• §8 remains design-level.
• There is no DDL, code, migration, trigger, table definition, or P44-6 execution.
• SQL-like phrases such as SELECT body are logical workflow descriptions, not implementation DDL.
• Concurrency is explicitly deferred under OPEN IU-0-ζ.

Caution: when moving to implementation, SELECT body WHERE canonical_address must be treated as illustrative only; physical schema must be chosen by APR/P44-6.

3. MUP detail

PASS.

• Tier 0 is exactly the 15-element gate: 10 UMC + 3 identity required + 2 publication required.
• Tier 1 is correctly recommended/warn-only, not block birth.
• Tier 2+ is deferred.
• This matches 07 §4.3 and 07b §5.2.

4. Pilot plan

PASS.

• Pilot scope remains 3-5 docs.
• §10.4 explicitly says no P44-6, no production migration, no users outside dev, no legacy vector, no >5 docs.
• SC-6 keeps legacy KB vector non-impact as a success criterion.

5. OPEN/TD/Risk

PASS.

• Track A is correctly marked RESOLVED.
• Remaining high-priority items are still OPEN: implementation pattern, unit_kind extensions, slice boundary, IU collection, shared/separate outbox.
• Risks still cover duplicate KB+IU, outbox stuck, legacy mutation, schema divergence, and implicit P44-6.

Directive to Opus

Stop content polishing for IU-0 Modular v2 unless User asks for a specific amendment.

Next step is not another rewrite. Prepare a concise handoff note for the next track:

• Confirm IU-0 Modular v2 baseline is active on KB.
• List the three active files.
• Summarize what is allowed next: targeted patch only, no structural rewrite.
• Propose the next work item: Pilot planning pack, not execution.
• Pilot planning pack should be small: one short document only, max 3-5 docs scope, no DDL/code/P44-6.

Do not start the pilot. Do not create implementation tasks. Do not modify the three IU-0 files unless User gives a concrete patch request.
