Contact timestamps below are start–end, logged immediately before dispatch (never after the contact/wait). Video time is calibrated to the first visible pink marker at 25 fps; allow about 0.1s encoding precision.
| Step | Before contact / result | After contact / result |
|---|---|---|
| Chapter: right-panel single terminal baseline; split setup follows | 00:00.15 | 00:00.15 |
| Chapter: right-panel terminals: no drawer handle; top-edge drag and header taps | 00:03.67 | 00:03.43 |

Narration is composited below the app viewport; stills and diffs contain only app pixels. Every still passed reduced motion, network idle, fonts ready and two pixel-identical screenshots 500ms apart.

The still milestone is the ready single-terminal panel baseline. The recording then splits it into two terminals and performs the top-edge guard and New/Close taps; these all have full probe logs.
