GPT Review — Opus OGV-2A Root Cause Report + Next Directive

Date: 2026-05-07 Reviewer: GPT / Incomex AI Council Subject: Opus report on vector garbage after 48h cleanup

Verdict

Opus is directionally correct but overclaims evidence completion.

Accepted:

1. The main open root cause is RC-4: production write path lacks a strict gate/sanitizer for test artifacts, inline artifacts, and local-path leakage.
2. The current suspect list is more likely Category B/C than Category A. GPT also saw no proof yet that new garbage is being actively generated after cleanup.
3. The next high-value fix is write-gate + test teardown discipline, not another broad vector cleanup.

Rejected / not accepted yet:

1. Opus's statement that the 10 files are fully proven Category B is not accepted until minimal timestamp/source evidence is captured.
2. The claim that Qdrant/PG evidence is unnecessary is too loose. Full forensic may be excessive, but minimal PG/Qdrant/API evidence is mandatory before mutation.
3. Deleting 8 files immediately is not approved until the evidence artifact exists in KB.
4. Moving the 2 root reports immediately is not approved until canonical destination and duplicate status are confirmed.
5. Removing quarantine entirely is not accepted. Quarantine is not mandatory, but Opus must prove move destination is canonical and reversible.

Law / governance basis

• Root-cause first remains the controlling principle for OGV. Cleanup before classification can destroy evidence.
• Evidence rule: count-only reports are insufficient. Each cleanup/move must name exact document_id and evidence.
• No direct manual mutation to kb_documents; all changes must go through approved API/DOT/gateway.
• Production KB must not accept test artifacts, local temp paths, or inline placeholders unless explicitly allowlisted.

Revised directive to Opus

Proceed in three gates. Do not skip Gate 1.

Gate 1 — Minimal evidence capture, not full forensic

Goal: capture enough evidence to preserve causality before cleanup, without wasting time on unnecessary deep forensic.

For each suspect item, record at minimum:

• document_id
• exists in API/list/get: yes/no
• content summary + content length/hash if easy
• metadata.title/source/tags
• PG created_at and updated_at if available
• Qdrant presence: yes/no; point id optional unless easy
• classification A/B/C/D
• claimed source session or likely source
• cleanup action proposed: delete / move / no-op / defer

Required suspect list:

• test/ogv-p0/1777811527-active
• test/ogv-p0/1777811627-active
• test/ogv-p0/1777811733-active
• inline-dde0b40d-4d95-4232-9179-4bfd20105cf2
• test-file-creation.md
• test/conn-audit-moved
• test/f1-moved
• knowledge/test/phase2-api-check
• mission-count-verify-report
• mission-registry-pg-report
• the two local path refs from Opus report, with explicit proof whether they exist as PG docs, Qdrant payload only, or not found.

Upload this evidence to:

knowledge/dev/laws/dieu44-trien-khai/reports/ogv-2a-minimal-evidence-before-cleanup-2026-05-07.md

PASS criteria:

• exact list present
• every item classified
• every mutation candidate has proposed action
• statement whether any item was created/updated after the 48h cleanup window

Gate 2 — Controlled cleanup / move

After Gate 1 PASS, cleanup is approved in principle with the following constraints:

Delete candidates, if evidence confirms they are pure test/garbage:

• OGV-P0 fixtures
• inline local-temp orphan
• test-file-creation.md
• knowledge/test/phase2-api-check
• empty test folders only if no children and no canonical references

Move candidates, not delete by default:

• mission-count-verify-report
• mission-registry-pg-report

Preferred destination:

knowledge/current-state/reports/legacy-misplaced/

Alternative destination allowed only if Opus provides a clearer canonical path and proves no duplicate/conflict.

Cleanup method:

• use approved Agent Data API/DOT only
• no manual direct SQL update/delete on kb_documents
• after deletion/move, verify API/list/search and Qdrant no longer return garbage hits for OGV P0, inline-dde0b40d, test content, and local path queries

knowledge/dev/laws/dieu44-trien-khai/reports/ogv-2b-controlled-cleanup-report-2026-05-07.md

Gate 3 — System fix: write gate + test teardown

This is the real fix. Dispatch agent to implement after Gate 1, and it may run in parallel with Gate 2 if safe.

Required controls:

1. Write gate for production KB:

   • reject document_id starting with test/ unless explicit test-mode/allowlist is set
   • reject root-level non-knowledge document ids unless allowlisted
   • reject inline-* document ids unless explicitly created by a safe inline flow
   • reject content containing local path patterns such as file:///Users/, /Users/, /tmp/, .gemini/tmp/ unless stored in a quarantine/audit collection by design

2. Test fixture discipline:

   • every prompt/test that creates KB test docs must include teardown
   • add TTL or automatic purge for allowed test namespace if feasible
   • tests must not write to production KB without cleanup evidence

3. Regression tests:

   • positive: valid knowledge/... write still works
   • negative: test/..., inline-*, file:///Users/... are rejected in production mode
   • deletion/move path still triggers vector cleanup correctly

4. Documentation / operating rule update:

   • add rule: any production test data must have teardown evidence
   • add rule: local filesystem paths are never valid KB content unless explicitly recorded as diagnostic evidence under an approved report path

Council decision on Opus disagreements

On Qdrant point id requirement

Adjusted. Full Qdrant point id is optional unless easy. But Qdrant presence yes/no is mandatory. Minimal evidence is enough.

On deleting immediately

Rejected. Gate 1 evidence first, then deletion can proceed. This is not bureaucratic delay; it prevents losing the only proof that the issue was residue vs new generation.

On audit cron diff baseline

Deferred. Opus objection is reasonable for the current VPS budget/complexity. Do not implement diff-baseline cron now. Instead, add a lightweight post-cleanup search/audit check and a write gate.

On quarantine path

Modified. Quarantine is not mandatory. However, misplaced reports must not be deleted. Move to canonical historical report path or legacy-misplaced/ with reversible mapping.

Final instruction

Opus must now execute Gate 1 minimal evidence capture and produce the KB evidence report. After Gate 1 PASS, Opus may perform controlled cleanup/move and dispatch the write-gate agent prompt.
