CI / Build and push docker image (push) Successful in 2m42s
Migrate the backend from pip to uv
Replace requirements.txt with a uv workspace and lockfile, install the five tavolo packages from packages/* in development and non-editable in the image, and build the Docker image with uv. Move dev tools to a PEP 735 dependency group and refresh the locked dependency versions.

# tavolo-scopa
Scopa — the classic Italian fishing game — in its two-player form and in
the four-player fixed-partnership variant (*scopa a quattro*), as
[`tavolo-platform`](../tavolo-platform/README.md) game implementations.
The optional *asso pigliatutto* creation option turns either variant into
**scopa d'assi**.
## Contents
- `state.py` — `ScopaState` (pure game data: phases, players, hands,
table, the deck persisting between rounds, scores, deadlines),
`PlayerState`, `Card`, `Move`, with JSON (de)serialization. No session
envelope, no transport, no I/O.
- `engine.py` — the pure rules engine: deck, legal captures, plays,
auto-play, round re-dealing, hand scoring (carte, denara, settebello,
primiera, scope), the optional asso pigliatutto capture, hand-end
acknowledgements. Deterministic and I/O-free apart from logging, so the
whole rule set is unit-testable.
- `errors.py` — scopa-specific errors (`CardNotInHand`); every other
failure mode is a shared `tavolo.platform.errors` subclass.
- `plugin.py` — `ScopaEngine` (two players) and `ScopaQuattroEngine`
(four players in fixed partnerships): the platform-facing adapters.
They translate create/join/websocket actions/deadlines into
rules-engine calls and back, validate the
`target_score`/`asso_pigliatutto` creation options (the match target
defaults to the traditional 11 points for two-player scopa and 21 for
scopa a quattro), and extract the `MatchResult` (teams, winner,
per-player scores and the match summary persisted as the match's JSON
`result`).
Timeouts are constructor arguments (`turn_timeout_seconds`,
`hand_ack_timeout_seconds`), wired from the environment by the
application composition root.
## Development (from `server/`)
```sh
uv run python -m unittest discover -s packages/tavolo-scopa/tests
uv run mypy -p tavolo.scopa
```
`test_engine.py` covers the pure rules; `test_plugin.py` covers the
platform contract (actions, deadlines, serialization, results).
