# Recording and screenshots

1. Pick the computer (`computer_list`, or pass `computer` — it switches).
2. Check `request_access` when readiness is unknown. On a supported target,
   use `recording_start` with optional `display`, `region`, `fps` and
   `durationSec` (macOS auto-stop), or `intervalMs` (HarmonyOS snapshot cadence).
3. Do the work (or let the user do it).
4. `recording_stop` with the returned `id` → finalized file path + bytes.
5. `recording_list` shows everything saved; `recording_status` checks one.

Platform truths:

- **macOS**: ScreenCaptureKit inside the signed helper captures a display or
  region straight to .mov — no system recorder selection UI and no desktop
  dimming overlay. If capture is denied, Screen Recording permission is
  missing for whoever ran it: the Codewhale Computer Use app when
  `request_access` says `via: "app"`, else the terminal that hosts the
  server — tell the user which, do not retry.
- **Windows and Linux**: recording is unavailable pending session-owned
  recorder cleanup. Use screenshots; installing ffmpeg does not enable it.
- **HarmonyOS**: no native CLI recorder; the backend captures
  `snapshot_display` frames at `intervalMs` and muxes with ffmpeg on stop.
  The receipt labels the mode `snapshot-series` — never call it real-time.

Screenshots: `screenshot` returns the saved path and raster geometry; `zoom`
crops the latest raster when a target is too small to read.
