# Battery details widget on the board (HDMI, 1280x800)

Evidence class: injected pointer + operator swipe + native grim capture.
Not a camera recording.

## Steps

1. Injected `swaymsg seat - cursor` right-click on empty Home at (640,400)
   opened the Home menu; a click on Widgets showed the picker
   (`picker-widgets-page-1280x800-grim.png`, "Battery - Details" in the second
   column).
2. Injected click on the "Battery - Details" row (940,435). Page 1 had no free
   4x2 space, so the widget was placed at slot 0 of a new page 2
   (`home.json` page 2 slot 0 = `battery_details`); page 1 stayed in view.
3. The operator swiped to page 2 on the board's trackpad. Injected
   press-and-move via `swaymsg cursor set`/`cursor move` did not deliver
   motion to the client, so the scripted page turn was not possible.

## Limits

- Only the full, idle, unplugged state was observed; the charging and
  discharging lines (time to full/empty, USB input line) are covered by host
  renders only.
- The placement used an injected click, not a physical trackpad click.
- A widget that does not fit the page in view lands on another page without
  bringing it into view; observed here, left for a follow-up change.
