- Deal the hands from the shuffled stack and draw the trump card from it, so the trump card is in nobody's hand and cannot be played - A wizard or jester as trump card means no trump suit (previously a wizard let the dealer choose); remove the trump selection phase, the ChooseTrump action, the trump picker UI and the AI trump actions - Completed tricks carry their round's trump card, so the table keeps showing the matching trump card while the last trick of a round is displayed - Card corners are no longer rotated, so 6 and 9 cannot be confused - Trump label explains why there is no trump (wizard, jester, last round) - Tests: trump card never dealt, special cards give no trump, tricks keep their trump card Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# wizard_ai
|
||
|
||
AI player for the Wizard server. The actual RL model is still to be implemented; this package
|
||
provides everything around it.
|
||
|
||
- `agents/` — `Agent` interface (`act(observation) -> action`) plus `RandomAgent`,
|
||
`HeuristicAgent` (baseline / fallback) and `ModelAgent` (wraps a `Policy`)
|
||
- `model/encoding.py` — observation → fixed-size feature vector (`FEATURE_SIZE`), and the fixed
|
||
action space (21 bids + 60 cards) with legal-action masks; works for 3–6 players
|
||
- `model/policy.py` — **the place to plug in the model**: subclass `Policy`, implement
|
||
`select`, `update`, `save_weights`/`load`, register with `@register_policy`.
|
||
`UniformPolicy` is a placeholder so the pipeline runs end to end.
|
||
- `training/env.py` — turn-based multi-agent environment around `wizard_game`
|
||
(reward = score change per round / 100)
|
||
- `training/self_play.py` — self-play loop collecting per-player trajectories and calling
|
||
`Policy.update`, with checkpointing
|
||
- `training/evaluate.py` — play agents against each other (mean score, win rate)
|
||
- `service/client.py` — production: connects to `ws://wizard_server:8083/internal/ai`,
|
||
answers `decide` requests, reconnects automatically
|
||
|
||
```bash
|
||
pip install -r requirements-dev.txt
