Media selectors now use native host state when available and fall back to observable HTML audio/video properties. This fixes ordinary elements matching paused/seeking states, playback at time zero or during buffering, and muting that depended on the audio content attribute. Buffering can match while playback remains active. Timed stalls and volume locks require native support; the engine does not infer them from a network flag.
Time selectors delegate to the host timeline and match nothing when it is unavailable. Functional
:current()validates a nonempty compound-selector list, including with no candidates, and follows existing forgiving-list behavior.The changes follow the draft resource-state definitions and time-dimensional definitions. The retained browser assertions now live under
test/repo/e2eand run through the default CI browser command. New tests cover real playback, pause, seeking, muting, completion, native delegation, unsupported-host fallbacks, and malformed time selectors. The two archived expected failures are passing contracts; host-only limitations are documented indocs/media-time-state.md.Rebased as one commit onto the completed selector and benchmark changes. Validation: 585 Node tests, 22 packed-package tests, 20 existing browser tests, 7 media/display browser tests, and 58 WPT pages pass. Types, lint, formatting, repository checks, and coverage thresholds pass. Combined coverage: 86.42% statements, 77.72% branches, 85.16% functions, 85.31% lines.
