Recovery Method Detail

Original spec (~50KB, 14 sections A–N + 11 packs + 18 open questions) was authored by Opus 4.7 in session 2792e9a0 on 2026-05-10 but failed to upload to KB due to MCP agent-data server timeout (3 consecutive calls timed out at ~4 minutes each).

KB path requirements/p3d-information-unit-text-as-code-requirements-spec.md confirmed NOT_FOUND via batch_read before re-author.

Re-author derived from:

1. SSOT completed-state matrix (3 files: base + addendum + final patch) — verified and agreed by GPT + Opus
2. Outline trace from session 2792e9a0 conversation_search results
3. Current conversation context (full rà soát 4 vòng over ~2 hours)

Coverage Assessment

Section	Source	Grounding
§A Strategic purpose	SSOT + outline	Grounded in SSOT
§B Do-not-rebuild (16 items)	SSOT completed-state (all 3 files)	Directly from verified SSOT
§C Runtime foundations	SSOT + conversation evidence	Grounded — snapshot numbers
§D Design foundations (9 items)	SSOT + KB paths	Grounded
§E Gaps (9 branches)	SSOT remaining-work + outline severity	Reconstructed from outline
§F TAC↔IU reconciliation	SSOT item #3 + outline	Reconstructed — options from context
§G Canonical contract (16 concepts)	Outline (16+8) + P38-XC	Reconstructed — AC re-derived
§H–§M Requirements (6 sections)	Outline structure + SSOT gaps	Newly written from context
§N Roadmap (15 packs) + OQ (10)	SSOT agreed order + outline 18 OQ	Roadmap grounded; OQ top-10 selected
§O–§P Attestation + Conformance	Standard pattern	Newly written
§Q Coverage declaration	Self-assessment	Newly written

Known Differences from Original

1. Original had 18 open questions → re-author selects top 10 (by relevance to Pack 1)
2. Original had per-pack detail (purpose/inputs/outputs/non-goals/risks/acceptance/executor) for 11 packs → re-author has condensed table with acceptance criteria for 15 packs (aligned with final SSOT roadmap)
3. Original §E severity ratings may have been more granular (per-gap)
4. Original §B evidence paths may have had exact report filenames (this version references folder/collection level)
5. Re-author adds §Q (coverage declaration) not present in original structure

Sections NOT in Original That Were Added

• §O Hard Boundary Attestation (explicit in re-author, may have been implicit in original §16)
• §P Đ44 Conformance (was §15 in original)
• §Q Coverage Declaration (new — required by GPT directive for re-authored spec)

Recommendation

Spec is ready for GPT review. If GPT approves, proceed to:

P3D_PACK_1_IU_CANONICAL_CONTRACT_AND_TAC_IU_RECONCILIATION

Runtime checkpoint agent prompt is available at:

knowledge/dev/laws/dieu44-trien-khai/prompts/p3d-step1-runtime-checkpoint-agent-prompt.md

Checkpoint should be dispatched to Codex/Claude Code by User (GPT queue dispatch blocked by API field constraint).
