Verdict

PASS — OGV-2C accepted. OGV-2 case may be closed. Return to mainline work.

Agent implemented the write gate according to OGV-2C R2 + GPT addendum. Opus's closure recommendation is accepted.

Evidence accepted

• Discovery found FastAPI, real payload schema document_id + content.body, _error() envelope, APP_ENV=production, and the true chokepoint.
• Gate placed at create_document() in server.py, which covers REST POST /documents and MCP upload_document because MCP builds DocumentCreate and calls create_document directly.
• Four rules implemented:
  • R1: block test/ in production unless KB_TEST_MODE=true.
  • R2: block inline-.
  • R3: allow only knowledge/, operations/, registries/ for new creates; no reports/ convenience allowlist.
  • R4: block bare local path / file URI documents while allowing long diagnostic reports that mention paths.
• 8/8 live API tests passed: 3 positive HTTP 200 and 5 negative HTTP 422 with rule codes R1-R4.
• Post-deploy verification used actual HTTP status capture.
• Test docs were cleaned through existing DELETE API; delete path was not modified.
• Pre-existing KB docs were not cleaned/moved/deleted during OGV-2C.
• Commit hash recorded: a40b217.
• Rollback path recorded: git revert a40b217 + container copy/restart.

Non-blocking follow-ups

These do not block closure or mainline return:

1. PUT /documents/{doc_id} is not gated. This is acceptable for OGV-2C because update cannot change document_id; however, bare-path body content could theoretically be introduced by update. Track as a small follow-up only if the risk becomes relevant.
2. Existing stale reports/* and tham-khao/* docs were intentionally not touched. New creation is blocked by R3. Cleanup/move, if desired, should be a separate low-priority hygiene task, not part of OGV-2.
3. Operating-rule lesson should be recorded later without blocking mainline: every production test prompt must include teardown evidence; write gate belongs at API chokepoint.

Decision

• OGV-2A evidence: accepted.
• OGV-2B cleanup/move: accepted.
• OGV-2C recurrence prevention: accepted.
• Vector garbage emergency: closed.

Directive to Opus

Do not continue expanding OGV-2 unless a new failure appears. Do not start OGV-2D now.

Return to mainline work: Đ44 Pack 23 P3C2, with only a short closure handoff note if needed.

Recommended handoff line:

OGV-2 closed on 2026-05-07: cleanup complete, write gate deployed at create_document chokepoint, 8/8 live API tests PASS, commit a40b217. Mainline may resume.
