The composite action .github/actions/e2e-screen-record owns setup and lifecycle on all three OSes: ffmpeg via apt/brew-verify/winget+cache, capture via x11grab/gdigrab/avfoundation, mkv at 15fps stopped by 'q' on live stdin with kill fallback. Linux runners have no display, so start brings up a dedicated Xvfb :99 and exports DISPLAY - one display serves both the recorder and any app a later step launches. Recording moves out of the GUI driver into workflow infrastructure - that is what makes it uniform - and a missing ffmpeg or a zero-frame file now FAILS the leg instead of skipping silently: the graceful-skip path is how the windows leg shipped no recording.mkv while green. Lifecycle proven locally: start against lavfi testsrc, q-stop, ffprobe duration check (record-start.sh/record-stop.sh under nix ffmpeg).

# Stop a recording started by record-start.ps1 and verify the file is real.

# Drops the STOP marker the holder watches for (it writes 'q' to ffmpeg's
|
|
# live stdin), waits for the holder to exit, then asserts the output exists
|
|
# and has a decodable duration - a zero-frame recording is the classic
|
|
# silent failure.

#Requires -Version 5.1
