++# Card Game App Setup Verification
++
++This document contains findings from verifying the setup for the Python-based FreeCell Solitaire TUI card game.
++
++## Verification Checklist
++
++- [x] **card-game-app/pyproject.toml exists**
++  - Path verified: `card-game-app/pyproject.toml`
++  - Defines project metadata: `card-game-tui` (v0.1.0)
++  - Python requirements: `>=3.8`
++- [x] **card-game-app/main.py exists**
++  - Entrypoint verified. Includes `--smoke` CLI flag option for automated testing.
++- [x] **card-game-app/src/card_game_tui exists**
++  - Package layout verified:
++    - `src/card_game_tui/__init__.py`
++    - `src/card_game_tui/engine.py`
++    - `src/card_game_tui/tui.py`
++- [x] **Python files compile**
++  - Run command: `cd card-game-app && python3 -m py_compile main.py src/card_game_tui/*.py`
++  - Result: **Compilation Succeeded** (Exit code: `0`, no compilation syntax/type errors).
++- [x] **Headless Smoke Tests Check**
++  - Run command: `python3 main.py --smoke`
++  - Result: **Success** (Output: `Smoke tests passed successfully.`)
++
++## Summary
++
++The repository setup conforms perfectly to the initial specification. All core components (engine, CLI/TUI entry, requirements) are in place, successfully compile, and pass basic functional smoke tests.

+Read .ai/card-game-spec.md.
+
+Implement Card, Deck, Pile, or equivalent game-state types under card-game-app/src/card_game_tui/.
+
+Add focused unit tests under card-game-app/tests/.
+
+Run:
+cd card-game-app && python3 -m pytest tests/ -v
+
+Write status.json at workspace root: outcome=succeeded if tests pass and the data model is implemented, outcome=failed with failure_reason otherwise.
