GPT Review — P10B-1A D32 Segmentation Candidate v1

Date: 2026-04-29

Verdict

PASS directionally, but needs a small patch before P10B-1B.

Opus chose a good document and the segmentation shape is reasonable. However, the actual KB report is too compressed and misses a few required discovery artifacts. Under Zero Trust, we should patch P10B-1A before moving to insert/package generation.

What is good

• Scope is read-only; no mutation.
• Document choice fits P10B MVP: small law, simpler than D35.
• 23-unit segmentation is plausible.
• Tree shape is coherent: ROOT → top sections → child sections.
• Section type choices are mostly reasonable:
  • principle for §2.1–§2.3;
  • technical_spec for schema/quorum specs;
  • checklist for hardening rules and metrics;
  • governance_process for registration/reserved handlers;
  • changelog for changelog.
• Keeping §3.2 as one unit is acceptable for MVP because the two sub-tables belong to one conceptual section.

Blockers before P10B-1B

B1 — Source SHA not computed

The report says:

SHA256 | To be computed by Agent at execution time

This violates the discovery contract. P10B-1A must capture source SHA now, before segmentation is approved.

B2 — Per-unit body hashes/excerpts not present in actual KB report

The pasted artifact includes a unit table with excerpts, but the actual KB report only contains a compressed tree and expected rows.

P10B-1A should include:

• unit_key;
• parent_key;
• section_type;
• title;
• body_excerpt;
• body_sha256;
• sort_order;
• word_count if cheap to compute.

B3 — Vocab verification not explicit

The report notes checklist may need verification. It must be verified before approval. The report should state that all used section_type values exist and are active in tac_section_type_vocab.

B4 — Source metadata must be exact

The source metadata is plausible, but the report should record captured_at and SHA256. Revision alone is not enough.

Non-blocking notes

N1 — §3.2 grouping accepted for MVP

Keep §3.2 as one technical_spec unit. The #### subheadings can remain inside body as formatting. If round-trip render fails later, split in a patch.

N2 — Containers with heading

ROOT/S2/S3/S4 as structural headings are acceptable if heading type does not require body. P10B-1B package should verify body_required and description_required before insert.

N3 — Canonical address

D38-DIEU32-* is consistent with current regex constraint discovered in P10A. Still, P10B-1B must re-check current constraint before insert.

Directive to Opus 4.6

Patch P10B-1A → v1.1, read-only only.

Do not proceed to P10B-1B until patch is complete.

Required patch:

1. Fetch full D32 source again from knowledge/dev/laws/dieu32-approval-law.md.
2. Capture exact metadata:
   • path;
   • title;
   • revision;
   • content length;
   • SHA256;
   • captured_at.
3. Verify actual active section_type values from production PG or reuse current verified vocab snapshot if explicitly current.
4. Confirm all used types are active:
   • heading;
   • paragraph;
   • principle;
   • technical_spec;
   • governance_process;
   • process;
   • checklist;
   • changelog.
5. Produce expanded unit table with:
   • unit_key;
   • parent_key;
   • canonical_address;
   • section_type;
   • title;
   • body_excerpt;
   • body_sha256;
   • sort_order;
   • word_count.
6. Keep current segmentation unless source/hash analysis reveals an issue.
7. Upload patched report: knowledge/dev/laws/dieu38-trien-khai/reports/p10b-1a-d32-segmentation-candidate-v1-1-2026-04-29.md
8. STOP for GPT review.

Expected next state

After v1.1 patch, if all metadata/hash/vocab checks are complete and the 23-unit tree remains stable, GPT can approve P10B-1B package generation.

Status

• P10B-1A v1: directionally good, not yet complete.
• Next: P10B-1A v1.1 metadata/hash/vocab/unit-table patch.
