GPT Review — Opus P10B-1A v1.1 SHA Rebuttal and Next Directive

Date: 2026-04-29

Verdict

Opus rebuttal is partially valid, but P10B-1A v1.1 is not enough to proceed to insert/package.

Accepted:

• Desktop/Opus may not be the right runtime to compute SHA256.
• The segmentation itself should not be redesigned.
• The 23-unit D32 segmentation is directionally acceptable.

Not accepted:

• Deferring source SHA and per-unit body SHA until P10B-1B insert/package is too late for Zero Trust.
• The missing hashes should be resolved by a small read-only Agent micro-step before any package/insert path.

Reasoning

Prior precedent allows SHA pending in Desktop dry-run only if the next runtime/agent step computes it before mutation. However, P10B-1A is the approval gate for a segmentation candidate. The safe compromise is:

1. Keep Opus's 23-unit segmentation candidate unchanged.
2. Do not ask Opus Desktop to compute crypto if it cannot.
3. Dispatch Agent for a read-only hash/vocab evidence patch.
4. After that, GPT can approve P10B-1B.

This respects both role separation and the Zero Trust rule.

Assessment of Opus points

B1 — SHA256 rebuttal

Partially accepted.

Opus is right that Agent/runtime should compute SHA. But GPT does not accept waiting until an insert/package step. The correct place is a micro read-only patch step:

P10B-1A-HASH — D32 Hash/Vocab Evidence Patch.

B2 — Expanded unit table

Accepted directionally. The expanded table is useful, but the current artifact still lacks true per-unit hashes. It should be treated as candidate structure, not final evidence.

B3 — Vocab verification by evidence chain

Partially accepted.

Seed SQL + Gate C PASS is good supporting evidence, but Agent should still query production vocab in the micro-step because production state is the source of truth.

B4 — captured_at

Accepted.

Directive to Opus 4.6

Do not redesign D32 segmentation.

Do not proceed to P10B-1B yet.

Prepare and dispatch a short read-only Agent task:

P10B-1A-HASH — D32 Hash/Vocab Evidence Patch

Scope:

• read-only;
• no INSERT/UPDATE/DELETE;
• no DDL;
• no package generation;
• no Nuxt/KG/vector;
• preserve current 23-unit segmentation unless a concrete source mismatch is found.

Agent tasks:

1. Fetch full source from knowledge/dev/laws/dieu32-approval-law.md.
2. Record exact metadata:
   • path;
   • title;
   • revision;
   • content length;
   • SHA256;
   • captured_at.
3. Using the current 23-unit candidate, extract each unit body from source.
4. Compute for each unit:
   • body_sha256;
   • body_excerpt;
   • word_count.
5. Verify all unit body spans are covered:
   • no duplicate body spans unless intentionally structural;
   • no missing content except separators/formatting rules explicitly listed;
   • no unexpected overlap.
6. Query production tac_section_type_vocab and confirm these 8 codes are active:
   • heading;
   • paragraph;
   • principle;
   • technical_spec;
   • governance_process;
   • process;
   • checklist;
   • changelog.
7. Upload evidence report to: knowledge/dev/laws/dieu38-trien-khai/reports/p10b-1a-d32-hash-vocab-evidence-2026-04-29.md
8. STOP.

After Agent report:

• If hashes/vocab/body coverage pass, GPT can approve moving to P10B-1B.
• If mismatch appears, Opus patches segmentation only where evidence proves mismatch.

Status

• P10B-1A segmentation: directionally PASS.
• P10B-1A evidence: incomplete.
• Next: P10B-1A-HASH read-only Agent micro-step.
