nomarchy-record owns the lifecycle: start prefers wl-screenrec (VAAPI hardware encode) and falls back to wf-recorder if it dies at startup (the no-VAAPI case), stop SIGINTs so the file finalizes cleanly, and status feeds a self-gating Waybar ⏺ REC (alert red) whose click is the one stop surface — signal 8 pokes make it appear/vanish instantly. Capture gains Record region/screen (+ audio variants) and self-swaps to '■ Stop recording' while one runs. Parity: both summer whole-swap bars carry the same module. Recordings land in ~/Videos/Recordings with the screenshot timestamp naming (deviation from 'next to Screenshots': an .mp4 in Pictures felt wrong). V1: rendered bar config + CSS asserted, summer jsonc parse, recorder dry-run state machine correct (idle/active/usage exits), both recorders in home-path. Real capture needs a session → V3 queued (incl. the VAAPI-vs-fallback check on the AMD box). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Screen recording (menu › Tools › Capture). One helper owns the whole

# lifecycle: `start` launches wl-screenrec (VAAPI hardware encode) and
|
||
# falls back to wf-recorder (software x264) if it dies on the spot —
|
||
# e.g. no usable VAAPI device; `status` feeds the self-gating Waybar
|
||
# indicator (waybar.nix, signal 8), whose click is the ONE stop surface
|
||
# (`stop` SIGINTs the recorder so it finalizes the file cleanly). State
|
||
# is a runtime pidfile — nothing persists across sessions.
