ops ✅ — hidden video/audio fallback is stripped fail-closed; live Gitea rendering matched the filter, CI is green, and 53/53 contract tests pass.
Request changes: the new failure leaves a contributor with both sections visible in source and only says they don't exist. The inline finding names the missing recovery instruction.

Name the hidden
<video>/<audio>fallback and say to move Tracking and Attribution outside it; otherwise recovery is guesswork.Approved. The media-depth filter rejects provenance hidden in video or audio fallback while preserving provenance after the element. Verified 53/53 tests, shell syntax, diff hygiene, green head-bound CI, and both hidden/visible shapes against the live Gitea Markdown renderer.
Cost: +7.3–10.3 ms per invocation on an identical 18 KiB, approximately 4,000-tag local fixture (+8.6–10.3% on the stubbed path); at most 0.0034% of the configured five-minute job ceiling.
Observation: the added media-tag checks keep processing O(rendered-body bytes), and media suppression can only reduce VISIBLE_BODY output. Comparison: 25 invocations per build on the same deliberately tag-dense fixture; this excludes the renderer HTTP call. Attribution: the delta is consistent with two additional anchored regex checks per HTML tag. Observable return: hidden video and audio fallback provenance is rejected. Fine today.
The single next measurement if body scale becomes material is p95 end-to-end action duration grouped by rendered-body byte count.
Verification:
bash tests/run— 53 passed, 0 failed;git diff --check— passed.Approved. The extractor now discards rendered video and audio fallback subtrees before either provenance section is evaluated, closing the hidden-video path without trusting token presence inside the fallback. Gitea strips or externalizes the comparable hidden-container siblings I probed.

ops ✅ — hidden-content recovery now names the media/collapsed-details path; head CI is green, 53/53 contract tests pass, and shell syntax is clean.
Approved: the failure now tells a contributor why visible source sections were rejected and how to recover.
Reconciles prior review 7135:
<details>or<video>/<audio>fallback content; both media contract tests require that recovery instruction.Verification:
bash tests/run— 53 passed, 0 failed;bash -n check.sh tests/run tests/bin/curl— passed;git diff --check origin/main...HEAD— passed; exact-head CI — successful.Approved. The recovery text added after the prior security-approved extractor change is a fixed shell literal shared by the Tracking and Attribution failure paths; PR-controlled content cannot enter it, and it changes no acceptance decision. Both hidden media siblings now assert the actionable diagnostic.
Verification: live thread and every official review/comment; exact-head API diff and commit delta;
bash tests/run(53 passed);bash -n check.sh tests/run tests/bin/curl;git diff --check; exact-head CI success; exact-head commit trailer.Approved. The follow-up resolves the UX blocker: hidden media fallback now produces an actionable instruction to move Tracking and Attribution outside the collapsed or media container, and both media tests require that recovery text. Verified 53/53 tests, shell syntax, diff hygiene, green head-bound CI, mergeability, and hidden/visible shapes against the live Gitea Markdown renderer.
Cost: +120 output bytes on the missing-Tracking failure and +109 output bytes on the missing-Attribution failure; successful invocations emit zero additional bytes. The new head adds one constant shell assignment and no input-dependent processing, so the prior +7.3–10.3 ms measurement for the media-tag filter remains the action-path baseline.
Observation: the recovery guidance resolves the live UX blocker and does not change the O(rendered-body bytes) filter. Comparison:
cb30e5dto this head changes only constant diagnostic construction and the two expected test strings. Attribution: the incremental cost is bounded to constant assignment plus failure-only output. Observable return: contributors are told where hidden provenance sits and how to recover.
