+## Revision (2026-09-26)
 
-Earlier local mixes had **severe train∩eval state leakage** (debate ~91%,
-word_games ~87%, connect4 ~37% state_task overlap). This Hub revision is rebuilt
-with **0.00%** train∩test overlap on `state_task` fingerprints
-(`scripts/audit_train_eval_overlap.py`).
+Paired with Hub model revision **action-v2-qwen**
+(`dwidlee/systemone-lite-0.5b`).

+| Change | Detail |
+|---|---|
+| Chess | `staged_v1` — piece + destination, option caps ≤8 |
+| Spatial | `action_v2` — legal-only actions; Connect4 drop≤3 + win_now |
+| Sokoban `test` | Deadlock alerts balanced 75/75 yes/no; remap_alert_prob≈0.35 |
