You put canonical provenance inside You put canonical provenance inside `<details open>`; Gitea preserves `open` and shows both sections on load, but this branch increments `details_depth` and removes them. The check exits 1 claiming the visible sections are missing. Preserve open disclosure content unless a collapsed ancestor still hides it, and cover that recovery path.

Blocker: You submit The checked
Parse attributes as tokens, then add this exact reproduction. Blocker: You submit `<details title=" open ">` with canonical Tracking and Attribution inside. Gitea preserves the attribute and the browser keeps the disclosure collapsed, but this substring match treats the title value as the boolean `open` attribute. Exact head returns `check-naming: ok`.
The checked `<details open>` path has an unchecked `open`-inside-an-attribute-value twin on this line, and it takes the same hidden provenance.
`title` isn't sanitized away: authenticated `/markdown` returned `<details title=" open ">`. This isn't malformed HTML; it is valid rendered markup and remains collapsed.
Parse attributes as tokens, then add this exact reproduction.

Blocker: this regex matches Blocker: this regex matches ` open ` anywhere in the serialized tag, including a quoted attribute value. `<details title=" open ">` has no boolean `open` attribute, so the browser keeps its provenance collapsed; Gitea preserves that tag and exact-head execution accepts the hidden Tracking and Attribution. Recognize an actual attribute name boundary outside quoted values, then cover this exact body.

commented
Blocker: Blocker: `open` is searched across the whole serialized tag, so an ordinary attribute value containing whitespace-delimited `open` makes a collapsed disclosure visible to this filter. Gitea preserves `<details title="x open y">` without the boolean attribute; putting canonical Tracking and Attribution inside it renders collapsed, but exact head exits 0 with `check-naming: ok`. Match the actual boolean attribute without accepting text inside quoted attribute values, then add this reproduction.

Blocker:
curlhas neither a connection nor total timeout. A renderer that accepts the socket and stops responding can hold this step until the configured 5-minute job timeout; the prior local parser had no remote wait. Add bounded connect and total timeouts, then cover a stalled-response reproduction.
