Verdict

MASTER_DESIGN_REV2_R2_READY_FOR_USER_APPROVAL

The design now contains the agreed content at sufficient detail for approval as a document-only Master Design baseline. No additional design patch is required before user approval, unless the user chooses to change strategic direction.

Implementation remains blocked until user explicitly approves Master Design Rev2 R2 and opens a separate macro.

Confirmation of MP-D1..MP-D10

• MP-D1 PASS: W3C trace context corrected. trace_id is 32 hex only; traceparent is derived.
• MP-D2 PASS: completed/cannot_complete → in_progress is now reopen_for_correction, requires Điều 32 approval, preserves prior audit and original output snapshot.
• MP-D3 PASS: overdue → completed preserves SLA breach history and marks completed-after-deadline.
• MP-D4 PASS: blocked remains core state; UI severity escalates to red only by computed severity, not by new state.
• MP-D5 PASS: paused and cancelled are derived extension states, not replacements for the 9-state floor; adapter Gate A must support all 9 core states.
• MP-D6 PASS: render_iu_body now includes permission, governance, context checks, audit, permission-scoped cache key, and recipient-scope notification render.
• MP-D7 PASS: candidate registries cannot be referenced by executable artifacts until survey marks verified_live or a shape-adapter is approved.
• MP-D8 PASS: event payload max-size, forbidden-key deny-list, schema allowlist, and validation audit are explicit.
• MP-D9 PASS: AI/worker concise summaries require evidence fields, drill-down, and cannot auto-resolve without source event.
• MP-D10 PASS: Điều 34 is not a blocker for Master Design or Phase 0; Phase 1 law work must wait on OD1 or proceed under explicit future Điều XX boundary.

Coverage against agreed discussion

The following user-agreed requirements are present:

1. IU-centered architecture: IU is central assembly unit.
2. Workflow 2..500 steps uses same IU-backed step / IU bundle primitive.
3. Build once, reuse many times.
4. No duplicate IU body/instruction text.
5. IU version pinning for active workflows.
6. 4 Mothers are factories/orchestrators around IU: MOW, MOT, MOIT, MOUT.
7. MOW is orchestrator, not executor or queue owner.
8. MOT is task envelope, not executor.
9. MOIT is input/form registry bound to IU/task context.
10. MOUT is read-only output/reference/report view bound to IU/task context.
11. Workflow UI has Standard Process View and Runtime Progress View.
12. Runtime view tracks each step/task state, deadline, PIC, progress and evidence.
13. Traffic-light semantics and accessibility are present.
14. Long workflow UI for 100–500+ steps includes collapse, drill-down, search, critical path and blocked chain.
15. Governance UI is problem-first and avoids raw event noise.
16. Event 5-layer is present and reconciled: producers, broker/event bus, consumers/workers/executors, realtime gateway, DLQ/recovery/governance.
17. Queue does not run scripts; workers execute.
18. Nuxt does not read core queue/outbox/NOTIFY directly.
19. Realtime flows through backend gateway / SSE shell only.
20. DLQ replay is Điều 32-gated.
21. ACK/NACK, timeout, idempotency, retry, replay, heartbeat, trace/correlation are present.
22. PG remains SSOT; external tools are adapter/transport/executor/gateway only.
23. Existing infrastructure reuse is explicit and evidence-aware.
24. Candidate registries are survey-gated.
25. No-double-ownership law boundaries are preserved.
26. OSS strategy remains labels-only; no final tool selection.
27. Điều 34 remains decision path only.
28. Implementation sequencing remains separate and phase-gated.

Remaining items — not design gaps, but next workflow gates

These are not reasons to patch Master Design R2. They are explicit next actions:

1. IU_4MOTHERS_CANDIDATE_REGISTRY_SURVEY_DOCUMENT_ONLY_*X to close G7:

   • field_registry
   • input_form_registry
   • output_table_registry
   • dot_function_registry

2. Phase 0 implementation macros after design approval:

   • close G1 review_decision_id for IU split/merge;
   • close G2 fn_iu_post_cut_axis_materialize autowire into fn_cut_complete.

3. Council parallel:

   • OD1 Điều 34 decision: promote / merge into future Điều XX / keep draft.

4. Optional document-only archive:

   • upload raw 4 mẹ mở rộng.txt and Bắt sự kiện của PG(3).docx into KB if Council wants raw-source audit trail.

Decision

Recommendation to user:

Approve Master Design Rev2 Revision 2 as the document-only design baseline.

Then run the candidate registry survey macro before any Phase 1 substrate implementation. Phase 0 IU-side gap closure can proceed after design approval, independent of Điều 34 per MP-D10.

Forbidden still applies until a new macro explicitly opens implementation with its own authority pack:

• no PG mutation;
• no Directus mutation;
• no business Qdrant/vector write;
• no migration;
• no DOT command run;
• no law enactment;
• no final OSS selection;
• no UI deployment.
