P3D — Multidimensional Entity DB Design v2 Operational Contract Patch Report

Date: 2026-05-12 Author: Opus (Claude) Patched: v1 → v2

Top 9 v2 fixes

  1. Species count corrected — Glossary historical = 33, live runtime probes = 40. v1 said "33 hiện tại" = stale. v2 distinguishes both with live as current truth.

  2. Terminology tightened — "meta-layer" clarified as glossary term, not UI Layer. "meta-class" preferred. All Tầng/Lớp/Layer/Loài usage verified.

  3. Entity Living DB = operational contract — Each of 6 headings now has: runtime sources, min birth/migration requirement, enrichment path, not-cache/not-hardcode rule, 5C2 impact. Not just prose.

  4. Relation-pair matrix with 8 quy tắc from Điều 21 — Exact text recovered from Điều 21 v3.0. 8 rules in 4 groups (Identity, Structural, Dependencies, Implicit). Mapped to IU pilot status per rule.

  5. Matrix dimension registry contract — 10-field design contract (dimension_id → owner_law). Future dimensions = metadata rows, not code branches. Design-only, no DB implementation yet.

  6. Runtime gap matrix expanded — Added columns: TAC UI dependency, preserve_during_pilot, cutover_allowed_now, required_cutover_evidence. Default: preserve=true, cutover=false. Status distinguished: VERIFIED_LIVE / DESIGNED_ONLY / MISSING / DEFERRED.

  7. unit_version reframed — "Current P3D IU policy: subordinate artifact" instead of universal law claim.

  8. 5C2 resume claim downgraded — "may resume as parallel pilot after v2 review" + "targeted preflight allowed if GPT identifies assumptions". Not "can resume, no inventory needed".

  9. TAC→UI preservation section added (§O) — 7 subsections: current path (P10D-2B), tables feeding UI, behavior to preserve, redirect rules, forbidden changes, runtime evidence, UNKNOWN items needing inventory. Plus addendum §6 with 4 classification tags (NO_TOUCH / PARALLEL / FORBIDDEN / CANONICAL).

TAC→UI preservation findings

  • P10D-2B (commit 5ce3437) deployed Laws Page code reading from tac_* tables via Directus SDK
  • 4 tables feed UI: tac_publication, tac_publication_member, tac_logical_unit, tac_unit_version
  • Generic renderer with no doc_code branching (verified: grep = 0)
  • 2 UNKNOWN items: (1) CI deploy status of 5ce3437, (2) visual rendering verification — both marked NEEDS_TARGETED_AGENT_READONLY_SEARCH

Targeted inventory recommendation

No broad inventory needed. 2 targeted checks recommended (TAC→UI baseline verification, not IU prerequisites):

  1. Verify P10D-2B commit deployed to production Nuxt bundle
  2. Laws Page visual rendering curl/screenshot check

These confirm the baseline 5C2 must preserve, not prerequisites for IU migration itself.
