+## Source-media preview route
+
+The source tab uses the Rust streaming engine whenever the packaged playback
+capability is available. `playback_start(mediaId)` projects the selected video
+into a private one-track timeline at the project fps, then reuses the same
+FFmpeg RGBA decode, compositor, cpal audio clock, exact publication, and
+identity-scoped pause/seek/stop lifecycle as timeline playback. The source
+asset is read directly; this route does not create a whole-file proxy or
+transcode by default.
+
+Paused source frames and paused seeks use `composite_frame(sourceMediaId)` so
+they also decode through FFmpeg instead of switching back to WebKit. A terminal
+frame remains painted, Play rewinds it to frame zero, and selecting another
+asset retires the previous source session before accepting its publications.
+The ordinary `<video>` source preview remains only for the browser shell and a
+minimal build where the native playback capability handshake is unavailable.
