| # Shadow Interface Evolution Trajectories |
|
|
| OSWorld V2 evaluation trajectories from Shadow Interface Evolution: two evolved-variant held-out archives and two independently evaluated seed training/validation archives. |
|
|
| | 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`. |
|
|
| ## opus5xover25v15 seed |
|
|
| `opus5xover25v15_seed_trajectories.zip` contains 40 `claude_trajectory.jsonl` files from the independently evaluated `opus5xover25v15-seed`, preserving the original task directory structure. It covers 25 training tasks and 15 validation tasks; this is not a held-out 68-task baseline. Separate result and screenshot files are not included. |
|
|
| Across these 40 tasks, full-credit accuracy is 4/40 (10.0%) and mean partial score is 0.3135557204. These scores are from the seed records in `shadow_evolution_osworld_v2_opus5xover25v15.db` and are not directly comparable to the held-out scores above. The recorded run uses Qwen3.8-27B through OpenRouter/novita, a 1M context window, and a two-hour per-task time limit. |

| ## prime25v15r4 seed |
|
|
| `prime25v15r4_seed_trajectories.zip` contains 40 `claude_trajectory.jsonl` files from `prime25v15r4-seed`, preserving the original task directory structure. It covers 25 training tasks and 15 validation tasks; this is not a held-out 68-task baseline. Separate result and screenshot files are not included. |
|
|
| Across these 40 tasks, full-credit accuracy is 7/40 (17.5%) and mean partial score is 0.3890158997. These scores are from the seed records in `shadow_evolution_osworld_v2_prime25v15r4.db` and are not directly comparable to the held-out scores above. This seed was evaluated independently of `opus5xover25v15-seed`; their results and trajectories are distinct. |
|
|
| The recorded run uses Qwen3.8-27B through OpenRouter/novita, an effective 1M context window, and no per-task wall-clock limit. Although its saved interface configuration declares `context_window_tokens: 131072`, that field was not wired into Prime during this evaluation, so the model catalog window applied. Other step and runtime termination conditions may still apply. |
