Verdict

P3D4C0 PASS confirmed.

Agent executed the design/inventory task within boundaries: no PG mutation, no Directus mutation, no Nuxt code, no Hermes, no Codex dispatch, no new tool, and no external scheduler.

Accepted findings

• birth_notification_gap=CONFIRMED.
• Current P3D2 runtime deliberately skips unit_version.version_seq <= 1, so new IU births are not emitted as durable notification events.
• source_document_identifier=NOT_FOUND.
• import_batch_identifier=NOT_FOUND.
• batch_grouping_required=true.
• p3d2_trigger_hot_path_review=PASS.
• p3d2_trigger_heavy_work_found=false.
• Current P3D2 triggers are O(1): single insert plus at most one PK-indexed subselect; no joins, counts, aggregations, rollups, latest_readers, vector work, or derived processing on AI write path.
• debounce_mechanism_recommended=PG_CRON_STAGING.
• recommended_grouping_strategy=HYBRID.
• recommended_hook=UV_SEQ1_TRIGGER.
• expected_ai_pg_latency_impact=LOW.
• p3d4c_directus_exposure_status=PAUSE_UNTIL_BIRTH_BATCH_DESIGN.
• next_required_pack=P3D4C1_STAGING_OUTBOX_AND_WORKER_IMPLEMENTATION.

Roadmap correction

The previous P3D4C Directus exposure prompt is now paused. Do not proceed directly to public.v_iu_notification_board + Directus DOT exposure as if the runtime event taxonomy were complete.

New sequence:

1. P3D4C1 — draft/review implementation prompt for staging outbox + worker:
   • install/verify pg_cron prerequisite;
   • add nullable source_document_ref, import_batch_ref on information_unit;
   • create iu_notification_pending staging table;
   • create O(1) birth staging hook on unit_version.version_seq=1;
   • extend notification event taxonomy with new_piece_created, document_imported;
   • create worker fn_iu_notification_worker_tick();
   • schedule PG-native debounce worker;
   • add config keys for debounce seconds and batch piece threshold;
   • include rollback and tests.
2. P3D4C2 — resume Directus board exposure after P3D4C1 PASS, adapting the board view to the completed event taxonomy.

Non-negotiable architecture going forward

AI interaction hot path must remain O(1): append-only staging/event insert only. No COUNT, JOIN, aggregation, rollup, batch detection, latest_readers, vector computation, or other derived processing may run in triggers/functions on the AI write path.

Derived notification/batch processing belongs to a PG-native delayed worker window, default 90–120 seconds.

Directus/Nuxt remain read/display layers only: Directus exposes PG projections through DOT; Nuxt displays via existing assembly patterns and must not read PG directly or perform grouping/business logic.

Next allowed action

Create a P3D4C1 prompt for review. Do not dispatch implementation until GPT/User approval.
