Conversation
Accept OpenAI text+image_url parts and record a 3NF image catalog (payload / placement / later recognition events) so a PNG under "Please pay invoice 1042" stays findable. Hash inline bytes; do not store raw base64. Grounded in ColPali, LayoutLM, and RFC 2397. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>

Citation audit (APA 7th)This PR cites ColPali and LayoutLM as support for a 3NF invoice-image placement catalog that hashes Cited but not applicable to this implementation: Faysse, M., Sibille, H., Wu, T., Omrani, B., Viaud, G., Hudelot, C., & Colombo, P.

Review
The 3NF catalog slice is the right buyer cut: one payload digest, two placements on the reminder thread, no raw PNG in the JSON, recognition events left empty until a later OCR pass. Paper contracts, security hardening, and the invoice HTTP test hold.
That catalog is not yet searchable for the clients who will actually send the figure.
- Scheme mismatch.
_validate_content_partsaccepts any case ofdata:image/._parse_image_sourceonly treats lowercasedata:. ADATA:IMAGE/PNG;BASE64,...request returns 200 and then drops the figure. Inverse:HTTPS://is rejected by the validator whileurlparsewould accept it. - RFC 2397 whitespace.
b64decode(..., validate=True)rejects newlines. Mail clients and pretty-printed JSON wrap the payload. HTTP accepts the part; the catalog silently omits it. placement_idis schema-only. The ERD andimage_placementtable have a PK. The JSON row does not, so a later SQL writer cannot round-trip.- Stream path is dark.
chat_completion_chunksand_stream_route_completionnever attach the catalog.stream_routedoes not_store.save. A buyer onstream: truecannot do the documented next action, and a streamed run does not survive--state-dbrestart. - Credential leak on the completion.
adjacent_textis attached raw. Anapi_key=next to the pay line leaves the completion. Do not mask the AP mailbox or invoice number — those are the search keys.
Landing
Successor #684 074d051 applies those five fixes on top of this tip. Prefer #684 for merge. Do not land this PR and #684 in parallel.
Independent non-author APPROVE is still required. This automation will not self-approve or merge.
Buyer next action
Review #684. POST stream: true with a wrapped DATA:image/png;base64,... under Please pay invoice 1042 to ap@acme.com. Read the stop-chunk catalog: invoice 1042 and ap@acme.com present, PNG bytes absent, placement_id = image_placement_0_1.

validate=True rejects RFC 2397 whitespace. Combined with url.startswith("data:") (case-sensitive), a wrapped DATA:IMAGE/PNG;BASE64,... invoice is accepted by HTTP and then omitted from the catalog. Strip whitespace, casefold the scheme, then decode. Fixed on #684.

SQL/ERD image_placement.placement_id has no JSON counterpart. Add a stable image_placement_{message_index}_{part_index} so a later writer can round-trip. Fixed on #684.

This attaches adjacent_text without credential redaction. An api_key= next to the pay line leaves /v1/chat/completions even when include_orchestration_trace is false. Redact credential shapes only — keep invoice 1042 and ap@acme.com. Fixed on #684.

https:// is case-sensitive here while data:image/ is not. DATA:... is accepted then dropped by the parser; HTTPS:// is 400. Use the same casefold gate in both places. Fixed on #684.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current headd1b72211c73404b8fd6e2d6540bb9874d12e2b3b. -
