Verdict

P10A-1B PASS accepted.

Candidate v2: APPROVED FOR P10A-2 PROMPT DRAFTING, with conditions.

Do not run P10A-2 yet. Opus may now draft the P10A-2 insert + render prompt, but it must incorporate the conditions below.

Accepted evidence

• Root minimized: 78 bytes / 12 words.
• Preamble parent fixed: dieu35.preamble → dieu35.root.
• §4 split: parent + 7 technical_spec children, all below soft limit.
• §6 split: parent + 7 children.
• Section type diversity: 12 distinct types.
• All 30 units include description, word_count, and length_flag_expected.
• 0 hard_limit violations.
• 0 body_required / description_required violations.
• Zero mutation.

Technical decisions

D1 — Synthetic root

Accepted.

Keep dieu35.root as article structural parent with short non-duplicative body. Do not store full document body in root.

D2 — §4 split

Accepted.

Keep §4 split. For P10A-2, canonicalize keys where possible:

• replace dieu35.s4.sub2/sub3/sub4 with semantically clearer keys if mapping is stable, e.g. dieu35.s4.kh1, dieu35.s4.kh1b, dieu35.s4.1.1.
• If canonical renaming risks mismatch, keep current keys and record rationale.

D3 — Heading-only policy

Accepted.

Only dieu35.preamble uses heading. This is acceptable because it carries title/meta block and is a child of root.

D4 — Description backfill

Accepted with condition.

P10A-2 must regenerate descriptions before insert using a cleaner deterministic template, not the current first-line heuristic when it lands inside code/table blocks.

Recommended short template:

[MỤC ĐÍCH]: <one-sentence summary of unit role>.

or structured:

Mô tả: <summary>; Loại: <section_type>; Nguồn: <source heading>.

Descriptions must not begin with SQL code, table fences, markdown table rows, or raw code block markers.

D5 — §12 tombstone

Accepted.

paragraph is correct for the tombstone unit.

Soft-limit decisions

Preamble

Change dieu35.preamble from heading to paragraph only if the semantic role is content/meta paragraph rather than pure heading.

GPT decision: prefer keeping as heading for now and allow soft-limit exception, because it is a title/meta block and not a content paragraph. P10A-2 should record length_exception_reason='metadata title block; accepted for pilot' if schema supports it. If no exception field exists, log it in action report.

§8

Split §8 before P10A-2 if source has 4 clearly separable DOT pairs. Agent report suggests it does.

GPT decision: split §8 into 4 child units rather than carry a soft-limit exception. This improves the visible pilot and avoids known soft-limit flag.

Roadmap constraint reminder

The current label/type set is not final. Future architecture must support total labels, including independent labels and relationship/parent-child labels, growing 5–10× over time. This is a future P11 design concern, not a P10A blocker. P10A-2 should record label insufficiencies but not redesign schema.

Required P10A-2 prompt conditions

Opus may draft P10A-2 with these requirements:

1. Use candidate v2 as baseline.
2. Apply final candidate patch before insert:
   • split §8 into 4 child units if source supports it;
   • regenerate descriptions using clean template;
   • canonicalize §4 keys if safe;
   • keep root minimal;
   • keep preamble under root.
3. Generate an insert candidate package for GPT review before execution if possible. If the prompt combines generate+execute, it must contain exact preflight STOP points.
4. Verify actual schema fields for description, content/body fields, lifecycle fields, source reference fields, publication/member IDs, and any available length_exception field.
5. Use lifecycle states that keep pilot mutable unless governance requires enacted publication. Do not overstate that D35 has been formally migrated until User accepts visible result.
6. Insert only D35 pilot rows. No broad migration.
7. Use batch marker via tac_publication.id and record all inserted LU/UV/publication/member IDs.
8. Produce user-visible deliverables:
   • original markdown snapshot;
   • reassembled markdown from PG;
   • diff report;
   • tree/outline report;
   • row-count report;
   • rollback report/instructions.
9. No Nuxt/KG/vector.
10. No seed/role/permission/token/schema changes.

Directive to Opus 4.6

Draft P10A-2 — D35 Pilot Insert + Render Prompt v0.1 for GPT review.

Do not dispatch Agent yet.

The prompt must include:

• preflight checks;
• final candidate patch plan;
• insert execution path and role verification;
• transaction/rollback strategy;
• render/diff deliverables;
• exact STOP points;
• no broad migration.

After GPT reviews P10A-2 prompt, GPT will authorize if safe. User will be shown the visible result after P10A-2 completes.

Current state

• P10A-1 discovery: PASS.
• P10A-1B candidate v2: PASS accepted.
• P10A-2 prompt drafting: next.
• P10A-2 execution: not yet authorized.
