+ A terminal-based Spider Solitaire game built in Python using the standard library `curses` module, with zero external dependencies.
+ 
+ ## Key Features
+-- **Responsive Terminal Design**: Supports 1-suit (Spades), 2-suit (Spades & Hearts), or 4-suit (standard) gameplay, rendering beautifully on any standard terminal.
++- **Responsive Terminal Design**: Supports 1-suit (Spades), 2-suit (Spades & Hearts), or 4-suit (standard) configurations, rendering beautifully on any standard terminal.
+ - **Visual Card Highlighting**: Distinctive Red/White colors for card suits and full multi-card selection highlights.
+ - **Intuitive Keyboard Controls**: Smooth cursor-based navigation across tableau columns and vertical selection.
+-- **Full Undo/Redo Support**: Save states stored in a history stack so you can undo any mistake.
++- **Full Undo Support**: Save states stored in an undo stack so you can roll back any move.

+
+Check:
+- The app is under card-game-app/
+- It uses curses for the interactive TUI
+- It implements the requested game rules
+- README.md explains setup, run, tests, and controls
+- No generated files are outside card-game-app/ except .ai/ reports and root status.json
+
+Write findings to .ai/card-game-fast-verify.md.
+Write status.json at workspace root: outcome=succeeded if the app is demo-ready, outcome=failed with specific missing or broken items.

+I have successfully verified the completed terminal-based Spider Solitaire game application. 
+
+### 1. Test Execution & Smoke Verification
+Running the verification command:
+```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
+```
+- **Unit Tests**: All 7 test cases in `tests/test_game.py` passed in `0.01s`.
+- **Syntax Check**: All source files compiled perfectly (`main.py`, `game.py`, `ui.py`).
+- **Smoke Tests**: Non-interactive suite in `main.py` simulated card movement, undo, stock dealing empty-column constraint validation, run-clearing, and mock rendering. All smoke tests **passed**.
+
+---
+
+### 2. File and Directory Structure Checklist
+- **App Location**: All production and test code is located entirely within `card-game-app/`.
+- **External files**: No temporary files or unexpected edits exist outside of `card-game-app/` besides `.ai/` files and the root `status.json`.
+- **TUI Library**: Uses Python's standard library `curses` module with zero external dependencies, making it ultra-portable and clean.
+- **Controls & Setup**: `README.md` clearly explains setup, execution, tests, and controls (arrow keys for navigation, numbers `0-9` for column jumping, `u` for undo, `d` for dealing, etc.).
+
+---
+
+### 3. Verification Findings Written
+- Detailed verification findings have been written to **`.ai/card-game-fast-verify.md`**.
+- The workspace status has been set to **`succeeded`** in **`status.json`**.
