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 and the RSWT-Bench benchmark.

Transitions

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

Source	Train	Validation
Android in the Wild	639,758	13,392
MiniWoB++	986,151	–
GUIOdyssey	95,788	5,045
AndroidControl	70,514	670
AMEX	32,613	1,728
Total	1,824,824	20,835

Path	Content
`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
