# 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.
