+I have successfully implemented a terminal-based Spider solitaire game in Python using the standard library `curses` module, fully decoupled from the UI rendering layer to support both highly interactive terminal gameplay and non-interactive headless smoke testing.
+
+### Deliverables Created
+1. **Implementation Plan (`.ai/card-game-fast-plan.md`)**: A detailed and concise document describing our architecture, rule validation, terminal rendering setup, input handling, and test strategy.
+2. **Core Game Logic (`card-game-app/game.py`)**: Separate from the UI, implementing card representations, the full game loop state, deepcopy-based multi-step Undo/Redo stack, sequence and placement validation, run clearing, and stock dealing.
+3. **Interactive Curses UI (`card-game-app/ui.py`)**: A rich interactive standard `curses` interface featuring Red/White colors for suits, highlighted sequence selections, scrolling within columns, and full feedback status message prompts.
+4. **Main Entry Point (`card-game-app/main.py`)**: Parses CLI args to run the full interactive mode (with `--suits` count support) or the non-interactive verification mode (with `--smoke`).
+5. **Unit Tests (`card-game-app/test_game.py`)**: Implements standard unit tests for all features of the `SpiderGame` logic.
+6. **Documentation (`card-game-app/README.md`)**: User guide, keyboard shortcuts, and testing instructions.
+7. **Status File (`status.json`)**: Declaring `outcome=succeeded`.
+
+---
+
+### Verification and Test Runs
+
+**1. Running Non-interactive Smoke Verification:**
+```bash
+python3 card-game-app/main.py --smoke
+```
+*Output:*
+```text
+====================================================
+Running Spider Solitaire Smoke Test / Verification...

+Goal: Build a terminal-based Spider solitaire game in Python
+
+## Completed stages
+- **plan_app**: succeeded
+  - Model: gemini-3.5-flash, 126.8k tokens in / 22.7k out
+  - Files: /home/daytona/workspace/fabro/.ai/card-game-fast-plan.md, /home/daytona/workspace/fabro/card-game-app/README.md, /home/daytona/workspace/fabro/card-game-app/game.py, /home/daytona/workspace/fabro/card-game-app/main.py, /home/daytona/workspace/fabro/card-game-app/test_game.py, /home/daytona/workspace/fabro/card-game-app/ui.py, /home/daytona/workspace/fabro/status.json
+
+
+Read .ai/card-game-fast-plan.md.
+
+Build the complete app under card-game-app/ in one focused pass:
+- pyproject.toml
+- main.py
+- src/card_game_tui/ package
+- tests/ package
+- README.md
+
+Implement:
+- Card, Deck, Pile, or equivalent game-state types
+- Requested game rules: initial setup/deal where applicable, move/action validation, auto-complete or helper actions where applicable, win/loss condition, undo
+- Curses UI with card rendering, board layout, keyboard input, move/action selection, and help text
+- --smoke mode that imports the app, creates a game, renders a text snapshot or summary, and exits without curses interaction
+
+Run:
+cd card-game-app && python3 -m pytest tests/ -v && python3 -m py_compile main.py src/card_game_tui/*.py && python3 main.py --smoke
+
+Write status.json at workspace root: outcome=succeeded if the app builds, tests pass, and smoke mode works, outcome=failed with failure_reason otherwise.

+I have successfully built and structured the terminal-based **Spider Solitaire** game in Python under the `card-game-app/` directory according to your specifications.
+
+### Summary of Accomplishments
+
+1. **Structured Package Layout**:
+   - Reorganized game and UI modules under `card-game-app/src/card_game_tui/`.
+   - Setup `card-game-app/tests/` containing pytest-compatible unit tests.
+   - Configured `card-game-app/pyproject.toml` with `pytest` configurations (specifically, `pythonpath = ["src"]` to handle relative and absolute module paths effortlessly).
+   - Created clean, executable, and robust `main.py` entry point.
+
+2. **Game Logic & Constraints (`game.py`)**:
+   - Handles standard **Spider Solitaire** setups for 1, 2, or 4 suits with exactly 104 cards.
+   - Fully supports moving single or multiple same-suit decreasing sequences.
+   - Tracks completed runs (from King down to Ace) and clears them automatically from the tableau to the foundation, auto-revealing/flipping facedown cards.
+   - Restricts stock deals when there are empty columns on the board.
+   - Implements deep history state management for the **Undo** action using custom snapshot clones.
+
+3. **Responsive Curses UI (`ui.py`)**:
+   - Features rich text-based card rendering, color schemes (red for Hearts/Diamonds, default/white for Spades/Clubs), and beautiful board structure.
+   - Offers interactive sequence-splitting selection using **Up/Down** arrows, moving cards with **Left/Right** arrows, column-jumping using **0-9** keys, and **Undo** with **U/u**.
+
+4. **Robust Automation & Verification Mode (`--smoke`)**:
+   - Added a highly informative headless smoke simulation that boots the game engine, performs test moves, simulates deal/undo constraints, runs completed-run clears, and outputs a mock console visualizer without initiating curses mode.
+
+### Validation Commands Run
+All tests pass, code compiles perfectly without warnings or errors, and the smoke test executes successfully:
+```bash
+cd card-game-app && python3 -m pytest tests/ -v && python3 -m py_compile main.py src/card_game_tui/*.py && python3 main.py --smoke
+```
+
+The game's outcome state has been successfully updated in `/home/daytona/workspace/fabro/status.json`.
