- Selection: exactly 210 trajectories, with application/task families
reserved for held-out evaluation excluded (held-out-family exclusion).
- Transformation: navigation actions and screenshots were deterministically
converted to the AppGen/ms-swift multimodal SFT schema, then fixed to exactly
2,768 rows. Converted dataset SHA-256:
fa5281dc85fea09f9c3b09ee5d4cf7cd6a127995f801ddb650aca9442c6fede4.

Intended use
This checkpoint is intended to measure base-SFT transfer from real-world AMEX
navigation data and to support controlled held-out and AndroidWorld research
evaluation. Results should report the immutable data/base revisions above and
should not be interpreted as a general safety or reliability guarantee.
