# systemone-lite-phase2
Typed System One distill rows (`task` / `state` / `instructions` / criteria /
`label_alias`) for [`systemone-lite`](https://github.com/fritzprix/systemone-lite).
## Revision (2026-09-26)
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 |
Postmortem: repo `docs/NOTE_ACTION_V2_QWEN_POSTMORTEM.md`.
## Critical: train / test hygiene
**0.00%** train∩test overlap on `state_task` fingerprints
(`scripts/audit_train_eval_overlap.py`). Earlier mixes had severe leakage;
do not regress.
| Mechanism | Detail |
|---|---|
| `word_games` | Disjoint TRAIN / EVAL vocabularies |
| `debate_judge` | Held-out topics (eval never sees train motions) |
| Spatial / chess / CA | Eval states rejected against train state hashes |
| `nlp_cloze` | WikiText-2 **document-disjoint** (train split → train, test split → eval) |
**Do not mix `train` rows into `test` (or vice versa) when building local evals.**
## Splits
| Split | Rows | Role |
|---|---:|---|
| `train` | 240800 | SFT |
| `test` | 4700 | Held-out eval only |
Gym counts (train): `{"connect4": 35000, "game2048": 35000, "gridworld": 35000, "sokoban": 35000, "chess": 32400, "cellular_automata": 12000, "nlp_cloze": 12000, "word_games": 12000, "debate_judge": 10800, "resource_allocator": 10800, "ticket_dungeon": 10800}`
## Schema
Flat columns for Hub friendliness: `state` and `meta` are JSON strings;
`criteria_keys` / `criteria_values` parallel lists.
