Current authority — 2026-09-23 KST

  • protected base: main@83eba56149eb802cd63642c507c324c9976ec78e
  • exact head: 6545b5ff7ed88d98daad74ca3ba8f8606dad3fc4
  • state: open / Draft / mechanically mergeable
  • qualifying independent current-head APPROVED: none

This lane owns backend embedded-image ingestion only. It replaces tag-wide <img> matching with structural HTMLParser attribute parsing, preserves the narrow data:image/*;base64 allowlist, strict base64 decode, remote-image rejection, and source-position provenance. Review-found non-LF position drift was reproduced at b2e29b6a... and causally fixed at this exact head by aligning line starts with the LF semantics used by HTMLParser.getpos().

Exact-head product/security evidence

Repository-owned evidence remains terminal:

  • Tests 35065642195: SUCCESS;
  • SAST 35065642221: SUCCESS;
  • Security 35065642147: SUCCESS;
  • Required CodeQL 35065642188: terminal FAILURE at compatibility/verdict settlement.

The canonical producer bound to this exact head previously surfaced repository-baseline findings outside this two-file image-ingestion delta: Python py/insecure-protocol in lineageweave/http_client.py and py/polynomial-redos in lineageweave/post_chat.py remain owned by #974 or a verified successor; four JavaScript js/incomplete-multi-character-sanitization findings in frontend/src/postBodyDisplay.ts remain owned by #983 or a verified successor. Do not duplicate either owner repair here or add scanner exemptions.

Current independent review is non-accepting. CodeRabbit's source finding on non-LF position drift is repaired on this head. OpenCode submitted current-head CHANGES_REQUESTED because its coverage gate failed and explicitly synthesized no new source-backed product finding from that gate. That distinction does not make the review accepting: coverage and qualifying independent approval remain promotion gates.

The canonical central control plane has since moved to protected .github/main@e6334e229581a918e2f22de18733b76fa65d7e71; the older 64aa08d7... reference is historical. That owner movement does not retroactively turn this exact consumer receipt GREEN.

Promotion boundary

Keep this PR Draft and unmerged until the canonical owner findings converge through their owner lanes, Required CodeQL settles on a fresh unchanged consumer head against the then-current protected baseline, coverage/review gates are accepting, and qualifying independent approval exists.

No blind rerun, predecessor receipt promotion, synthetic status, remote-image fetch, owner-source copy, self-approval, force push, destructive rebase, source-neutral wake commit, or gate weakening is authorized.

extract_base64_images가 정규식 탐색 대신 HTMLParser 기반 파서를 사용합니다. 파서는 유효한 이미지 데이터 URI만 디코딩하고, 이미지의 문자 오프셋을 기록합니다. 새 테스트는 인용된 > 문자, 여러 줄 입력, 대소문자 및 잘못된 입력을 검증합니다.

_EmbeddedImageParser가 img 요소의 src 속성을 파싱합니다. 유효한 이미지 데이터 URI를 검증하고 Base64 공백을 제거한 뒤 디코딩합니다. 원격 이미지, 비이미지 소스, 누락된 src, 잘못된 Base64는 무시합니다. 결과에 원본 HTML의 문자 오프셋을 기록합니다.

Images in content containing CR or other non-LF line separators can be reported at the wrong source position. Align offset calculation with HTMLParser's LF-based positioning before merging.

- Around line 76-77: Update the line-offset construction around the loop
appending to self._line_offsets so offsets advance only at actual LF (\n)
characters, matching HTMLParser.getpos() rather than splitlines() separators
such as \r or \v. Ensure EmbeddedImage.position points to the real image tag
offset, and add a regression test covering input with a non-LF separator before
the image.

Pull request overview

OpenCode reviewed the current-head product diff. Coverage is a separate gate.

Changed files

  • lineageweave/image_content.py — Python module behavior
  • tests/test_image_content_quoted_tag_contract.py — regression suite

Findings

No source-backed product finding is synthesized from the coverage gate. A coverage miss belongs in the status comment.

  • Head SHA: 6545b5ff7ed88d98daad74ca3ba8f8606dad3fc4
  • Workflow run: 35152145897
  • Workflow attempt: 1
  • Coverage gate: failure

Review outcome

Coverage is a gate, not the review. This body reviews the changed product files.

OpenCode Review Overview

Coverage evidence did not pass, so approval is blocked. The formal pull-request review is the source-backed diff review, not this status comment.
