Shadow Interface Evolution Trajectories
Two archives of OSWorld V2 held-out evaluation trajectories from Shadow Interface Evolution.
| Archive | Evolution experiment | Variant | Trajectories | Full-credit accuracy | Mean partial score |
|---|---|---|---|---|---|
| prime25v15r4_if-006_trajectories.zip | prime25v15r4 | if-006 | 68 | 17/68 (25.0%) | 0.6240 |
| opus5xover25v15_if-010_trajectories.zip | opus5xover25v15 | if-010 | 68 | 16/68 (23.5%) | 0.5834 |
Each archive contains only claude_trajectory.jsonl files, preserving the original evaluation batch and task directory structure. Separate screenshot files, result files, and task-cache artifacts are not included.
Scores use all 68 held-out tasks as the denominator, counting infrastructure failures as zero. Both runs have infrastructure-imputed zeros for tasks 002, 018, and 024. Trajectory presence does not imply a successful or complete task execution.
The if-006 archive combines the original 33-task batch and the remaining 35-task batch. The if-010 archive is from the crossover experiment (opus5xover25v15), evaluated in run 20260906T174130Z.
