| # INTACT Goal E1 Single-Task Four-Slot 7/7 |
|
|
| This release contains 12 independently trained checkpoints: four tasks for each training seed (`0`, `42`, and `3072`). Each archive follows the repository convention of grouping four task shards by training seed. |

| ## Contract |
|
|
| - Original Goal INTACT, independently trained per task |
| - Four-slot Actor, 7/7 window, 8 frames, terminal goal `z7` |
| - One epoch, batch 256, workers 6, BF16 mixed precision, Math SDPA |
| - Train seeds `0/42/3072`; Official Direct evaluation seeds `0/1/42`, 100 episodes per cell |
| - 12 checkpoints and 36 evaluations passed; overall success rate 93.72% (3374/3600) |
|
|
| These checkpoints use the clean four-slot runtime. They are intentionally incompatible with the legacy five-slot Actor grammar documented for the paper E5 archives. |
