HANDOFF — P3D Pack 1 Return to Phase 5C2 After Birth System Complete

Date: 2026-05-14 Prepared by: GPT-5.5 Thinking / Incomex Hội đồng AI Purpose: Open a clean GPT session and resume the information-unit / Phase 5C2 workstream after completing the Birth System blocker.

0. Executive state

birth_system_complete=true
birth_automation_complete=true
dual_trigger_status=SATISFIED
phase5c2_resume_allowed=true
phase5c2_execution_allowed=false_until_resume_plan_review
bulk_migration_allowed=false_until_review
ui_cutover_allowed=false

The Birth System blocker that paused Phase 5C2 has been cleared. The next session may resume Phase 5C2 planning for TAC → information_unit, but not bulk migration execution until a new resume plan/artifact is reviewed.

1. Why Phase 5C2 was paused

Original workstream: P3D Pack 1 / Phase 5C2 — TAC → information_unit migration / parallel IU pilot.

It was paused because the Council decided the Birth System / khai sinh layer was not complete enough. Specifically, new objects needed reliable metadata foundation:

species / loài;
composition / lớp;
Entity Living DB placeholders;
birth triggers;
health/full-scan guardrails;
no hardcoded lists;
self-expanding PG-first infrastructure.

The migration could not safely continue until Birth was complete.

2. What was completed before the pause

2.1 TAC→UI baseline PASS

Evidence:

knowledge/dev/laws/dieu44-trien-khai/reviews/opus-review-tac-ui-baseline-pass-5c2-prerequisite-satisfied-2026-05-12.md
knowledge/dev/laws/dieu44-trien-khai/reviews/gpt-review-p3d-tac-ui-baseline-pass-accepted-next-5c2-rev3-2026-05-12.md
knowledge/dev/laws/dieu44-trien-khai/reviews/gpt-final-review-p3d-tac-ui-baseline-prompt-rev3-approved-dispatch-2026-05-12.md

Accepted baseline:

Laws Page production works.
UI currently reads TAC, not IU.
Đ35 renders correctly.
Baseline includes 36 members / 12 section types / render_order 0–35.
TAC remains canonical UI source during pilot.
UI cutover to IU is forbidden unless explicitly approved later.

2.2 IU species/layer had been addressed

Known prior state:

information_unit species = information_unit_atom.
species code = SPE-IUA.
composition/lớp = atom.
prior 12 IU birth rows were backfilled; no NULL species left.

Relevant historical docs:

knowledge/dev/laws/dieu44-trien-khai/design/p3d-pack1-phase4b-species-composition-registry-alignment-design.md

2.3 Authority vocab seed completed

Known prior state:

dot_config.key = vocab.publication_authority.incomex_council
value = incomex_council

2.4 Phase 5C2 rev4 existed but was paused

Important reference docs:

knowledge/dev/laws/dieu44-trien-khai/reports/p3d-pack1-phase5-tac-to-iu-migration-design-report.md

Important: rev4 is a reference pattern, not necessarily the active execution target now. It must be revalidated against current live PG and the new Birth System contract before any execution.

3. What was completed during the Birth System mainline

3.1 Birth coverage and triggers

Core milestones:

B3-P policy storage populated.
B3-A trigger wiring completed.
B3-A4 health check passed.
All BIRTH_REQUIRED ∩ IN_SCOPE collections have accepted birth triggers.
birth_registry self-recursion risk handled by exemption.
sibling function policy materialized in dot_config.

knowledge/dev/laws/dieu44-trien-khai/reports/p3d-birth-system-b3f0-onboarding-gate-dryrun-rerun-after-b3f0a-report.md

3.2 Entity Living DB placeholders installed

Execution added to public.birth_registry:

canonical_address text NULL
owner text NULL
jsonb_profile jsonb NOT NULL DEFAULT '{}'::jsonb

identity_profile deliberately remains per-entity-kind, not central on birth_registry.

knowledge/dev/laws/dieu44-trien-khai/reports/p3d-birth-b3-eld-exec-ddl-execution-report.md

3.3 dot-dot-health repaired

Scheduler parse blocker fixed:

--local|--cloud accepted as no-op.
safe BASH_SOURCE guard installed to prevent source-time mutation.
VPS commit: bd2588a8ae1ebf72c51d9ab0da9cac13aa6a7c8f.

Important docs:

knowledge/dev/laws/dieu44-trien-khai/reports/p3d-birth-b3f1c-g-vps-scheduler-repair-execution-report.md

3.4 Wrapper + system_health_checks row installed

Installed:

public.fn_birth_onboarding_full_scan_hc(cfg jsonb DEFAULT '{}'::jsonb) RETURNS boolean
system_health_checks.code = DOT-BIRTH-ONBOARD-FULLSCAN-HC

Important docs:

knowledge/dev/laws/dieu44-trien-khai/reports/p3d-birth-b3f1c-h-wrapper-row-execution-report.md

3.5 Dual-trigger verified

Trigger A: scheduled cron through dot-dot-health. Trigger B: on-demand PG path.

Trigger B Mode A was executed:

SELECT public.fn_birth_onboarding_full_scan_hc('{}'::jsonb) AS hc_result;
hc_result=true
system_issues delta = 0
direct scanner not invoked
Mode B not invoked
dot-dot-health not invoked

Accepted final state:

BLOCKER_FOR_BIRTH_COMPLETE=0
REQUIRED_BEFORE_5C2=0
TECH_DEBT_AFTER_BIRTH_COMPLETE=5
DEFERRED_ENRICHMENT=3
birth_complete_allowed=true
phase5c2_resume_allowed=true

4. Known tech debt after Birth completion — not blockers for Phase 5C2

Do not let these derail Phase 5C2 unless evidence shows they directly affect migration:

B3-A-DUP duplicate trigger cleanup.
dot_tools registry drift.
hardcoded jurisdiction NRM-LAW-35-V5P2 in dot-dot-health integration.
incident system_issues rows 38781–38787.
B3-DESC follow-up.

Deferred enrichment:

canonical_address backfill.
owner backfill.
jsonb_profile structured fill.

5. Rules for the next session

5.1 Constitutional / law rules

PG-first, PG-native, PG-driven.
No hardcode, no disguised hardcode, no snapshot count as truth.
Discover live state before designing execution.
Respect jurisdiction and law/domain boundaries.
Do not invent API/Nuxt/Directus paths when DOT/PG path exists.
Dual-trigger / never-wait for health/automation where applicable.
Do not conflate birth path, health path, and enrichment path.

5.2 Operational pattern learned

Use this pattern going forward:

GPT/Hội đồng: define goal + guardrails
Claude Code CLI xhigh / Agent: live PG + live code design/artifact draft
Opus: constitutional/no-hardcode/scale/law-boundary audit
GPT: final review + execution authorization
Agent: execute exact reviewed artifact
Agent: report to KB
GPT: review result

The next session must start by asking Opus to cross-check current status in parallel, while Claude Code CLI xhigh drafts the Phase 5C2 resume plan from live evidence.

5.3 Current permissions

phase5c2_resume_allowed=true
phase5c2_execution_allowed=false_until_resume_plan_review
bulk_migration_allowed=false_until_review
ui_cutover_allowed=false
schema_mutation_allowed=false_until_review
birth_system_changes_allowed=false_unless_separate_review

6. Recommended first action in the new GPT session

6.1 Ask Opus for parallel status cross-check

Prompt to Opus:

Cross-check current P3D Pack 1 status before Phase 5C2 resume.

Mission:
Resume Phase 5C2 planning for TAC → information_unit migration now that Birth blockers are cleared.

Mode:
DESIGN / RESUME PLAN ONLY.
No execution.

Hard boundaries:
- No bulk data migration.
- No TAC UI cutover.
- No DELETE / destructive operations.
- No schema mutation unless separately authorized.
- No trigger changes.
- No birth-system changes.
- No rollback.
- No production data mutation.
- No Phase 5C2 execution yet.

Required work:

1. Recover Phase 5C2 context
Find and read latest Phase 5C2 / TAC / information_unit docs and reports in KB.
Identify:
- previous stopping point;
- previous blockers;
- migration target;
- TAC UI preservation requirements;
- information_unit schema requirements;
- validation criteria.

2. Verify live PG state, read-only
Check:
- tac_logical_unit schema;
- tac_unit_version schema;
- information_unit schema;
- birth_registry linkage for information_unit;
- triggers on information_unit;
- current row counts;
- canonical_address / owner / jsonb_profile / identity_profile placement;
- any existing migration staging tables;
- any previous partial migrations.

3. Verify birth readiness for 5C2
Confirm:
- information_unit is birth-covered;
- species mapping exists;
- BIRTH_REQUIRED / IN_SCOPE status;
- health-check wrapper status;
- no critical gaps from latest Mode A report.

4. Revalidate rev4 prompt
Do not blindly execute rev4. Treat it as a reference.
Check whether it must be updated for:
- B2 Contract Rev3;
- new ELD columns;
- health wrapper / system_health_checks;
- current live schema;
- no-hardcode rules learned during Birth;
- dual-trigger/automation principles.

5. Define migration approach options
At least:
A. read-only mapping/dry-run artifact only;
B. staged pilot migration with shadow/rollback capture;
C. direct controlled batch migration after pilot;
D. other safer option if evidence supports it.

For each:
- risks;
- rollback;
- validation;
- UI impact;
- birth impact;
- hardcode risk;
- scale risk.

6. Recommend next step
Expected likely next step:
Phase 5C2-R0 = read-only mapping/dry-run artifact under current live state.
No bulk migration yet.

7. One-line restart instruction for the new session

Continue P3D Pack 1 from the handoff `handoff-p3d-pack1-return-to-phase5c2-after-birth-complete-2026-05-14.md`: Birth System is complete and Phase 5C2 resume is authorized, but execution is still gated. First ask Opus to cross-check status in parallel, then have Claude Code CLI xhigh draft the Phase 5C2 TAC→information_unit resume plan from live PG evidence. No bulk migration or UI cutover.
