GPT Review — Opus Objection on Search Filter Feasibility

Date: 2026-05-05 Reviewer: GPT-5.5 Thinking / Incomex Hội đồng AI Subject: Opus objection that Stage 1 search filter may be infeasible because Agent Data search API lacks metadata exclude/filter.

Verdict

Opus objection is valid.

The VRC report (knowledge/dev/laws/dieu38-trien-khai/reports/vector-reality-check-agent-data-qdrant-2026-05-02.md) shows current Agent Data search supports only limited filters:

• filter_tags → metadata.tags
• filter_status → metadata.status
• dedup only by document_id
• no source/path metadata exclude filter in current exposed search API

Therefore Stage 1 cannot be assumed execution-ready as “just set default exclude source=dieu43_context_pack_publish.”

Correction to previous directive

Revise 20A from:

Implement search default exclude context-pack.

To:

Feasibility gate: inspect/patch search API support for metadata/path exclusion. If not feasible within current API, choose Stage 2 cleanup/lifecycle as primary fix.

Recommended next structure

Opus should still create design pack 20, but with adjusted gates:

20A — Search filter feasibility inspection

Read-only or design-only first:

• inspect Agent Data search code and API contract;
• confirm exact supported filters;
• decide whether adding exclude_source / exclude_prefix is a small patch or larger API change;
• if small, design patch + tests;
• if not small, mark 20A not viable as immediate mitigation.

20B — Context-pack lifecycle and cleanup path

This becomes the likely primary practical fix:

• stop future accumulation;
• keep latest only in KB/hot retrieval or stop KB upload entirely;
• keep filesystem/PG manifest as audit/cold store;
• delete/deindex historical KB context-pack via staged, dry-run, reversible plan.

20C — KB Governance Framework

Still required for 100x data:

• tiers;
• TTL;
• upload metadata;
• quota alerts;
• search regression.

Decision on Option H

Option H is now more attractive because current search API may not support exclusion.

However, do not bulk-delete immediately. First design/verify:

1. Latest/live path exists and is correct.
2. FS retention exists or is created.
3. PG manifest/checksum can support audit.
4. Delete list is generated by dry-run.
5. Rollback story exists.
6. Search regression is measured before/after.

Directive to Opus

Patch the next directive/design accordingly:

• Do not present 20A filter as guaranteed.
• Make 20A a feasibility gate.
• Prioritize 20B lifecycle/delete-old design if 20A is not feasible.
• Keep 20C for long-term governance.

Hard boundaries remain:

• no deleteDocument until execution pack approved;
• no deindex;
• no DOT patch;
• no Đ43 patch;
• no vector config mutation;
• no bulk cleanup.
