| # LGWM data and RSWT-Bench |
|
|
| Data for **Right Screen, Wrong Transition: World Models as Verifiers for GUI Agents**: |
| the processed GUI transitions used to train [LGWM](https://huggingface.co/jiamingzz/lgwm) |
| and the RSWT-Bench benchmark. |

| ## Transitions |
|
|
| Each transition is a before screenshot, an action and an after screenshot. |

| | --- | --- | |
| | `processed/` | Screenshot shards (256×512 WebP) with actions, 36 GB | |
| | `index/` | One row per transition: shard, byte offsets of the two screenshots, action | |
| | `text_table.npz` | Action-text embeddings | |
|
|
| The viewer shows the `index/` tables. In them, `action_type` is 0 tap, 1 long_press, |
| 2 swipe, 3 scroll, 4 type_text, 5 key, 6 open_app, 7 wait, 8 click, 9 hover, 10 drag; |
| `x`, `y`, `x2`, `y2` are normalized to 0–1; `direction` is 0 up, 1 down, 2 left, 3 right. |
| |
| ## RSWT-Bench |
| |
| RSWT-Bench (Right Screen, Wrong Transition) is a donor-paired benchmark for |
| transition verification. In each of 222 donor pairs, a credential screen appears once as a |
| legitimate outcome and once, pixel-identical, as a hijacked one, so any detector |
| that sees only the resulting screen scores 0.5 AUC by construction. The test split |
| has 966 transitions; the train split has 6,786 for supervised methods. |
| |
| | Field | Meaning | |
| | --- | --- | |
| | `base` | Transition supplying the current screen and action | |
| | `obs` | Transition supplying the observed next screen | |
| | `pair_id` | Hijacked/paired-safe example pair | |
| | `donor_id` | Replacement-screen identity used for the paired bootstrap | |
| | `cls` | 1 hijacked, 2 paired safe, 3 legitimate credential, 4 surprising benign, 5 benign mismatch | |
|
|
