Final decision

PASS ACCEPTED. Vector/search reliability hardening is production-acceptable. Resume P3D Pack 1.

Accepted results

• Search boost behavior remains PASS.
• Production durability PASS: docker compose build agent-data and docker compose up -d --force-recreate agent-data succeeded.
• Canary PASS: 8/8 before rebuild and 8/8 after force-recreate.
• Qdrant unchanged: points_count=5015 before and after.
• No Qdrant mutation.
• No DB write.
• No PG schema mutation.
• No reindex.
• Health after: healthy.
• Audit cleanup implemented by code classification only.
• /kb/audit-sync auto_heal=false now reports status=clean, ghost_count=0, raw non-vectorizable classified.
• Unified search contract ready via optional collection_name support.
• Future IU vector can reuse rerank path; IU-specific boundary/chunking remains deferred.

Non-blocking residuals

These must be tracked, but they do not block resuming Pack 1:

1. /health.data_integrity.sync_status=warning remains due to ratio threshold 2.07 > 2.0; /kb/audit-sync is clean. This is observability threshold work, not current search failure.
2. Recency tiebreak is present but skipped because current Qdrant payload lacks timestamp fields. It will activate when future payloads include updated_at/created_at.
3. Canary cron is not installed. Script exists and passes; scheduled monitoring can be added later as ops housekeeping.
4. Compose file is outside the agent-data git repo. Change is backed up and checksummed; acceptable for now, but should be included in future infrastructure governance.

Decision on further vector work before Pack 1

No additional vector/search remediation is required before returning to miếng thông tin.

Do not open another vector patch now unless a new regression appears. The remaining items are governance/observability housekeeping, not blockers.

Resume Pack 1

Resume:

P3D_PACK_1_IU_CANONICAL_CONTRACT_AND_TAC_IU_RECONCILIATION

Next immediate action:

Run pending read-only verification prompts:

1. Step 1 runtime checkpoint: knowledge/dev/laws/dieu44-trien-khai/prompts/p3d-step1-runtime-checkpoint-agent-prompt.md
2. Pack 1 read-only inventory: knowledge/dev/laws/dieu44-trien-khai/prompts/p3d-pack1-readonly-inventory-prompt.md

Preferred: run both in one agent session using:
