+# Solitaire App Verification Report
+
+## Verification Overview
+The Python Klondike Solitaire game with a curses TUI located under `solitaire-app/` has been thoroughly verified. Both unit tests and the headless programmatic smoke test run with 100% success.
+
+### Test Run Summary
+- **Unit Tests**: 8/8 tests passed successfully via `pytest tests/ -v`.
+- **Smoke Test**: Passed successfully with exit code 0 via `python3 main.py --smoke`.
+- **Compilation Check**: No syntax or byte-compilation issues found across all modules via `python3 -m py_compile main.py src/solitaire_tui/*.py`.
+
+---
+
+## Checks & Requirements Validation
+
+### 1. File Structure and Location
+- The application resides strictly inside the `solitaire-app/` directory:
+  - `solitaire-app/main.py`: Interactive entry point and smoke test trigger.
+  - `solitaire-app/pyproject.toml`: Pytest and package configurations.
+  - `solitaire-app/src/solitaire_tui/`: Contains the modular application package.
+    - `__init__.py`
+    - `game_logic.py`: Game states, move validation, and histories.
+    - `tui.py`: Custom curses interface drawing and input handling loop.
+  - `solitaire-app/tests/`: Unit testing suite.
+    - `__init__.py`
+    - `test_game_logic.py`: Verification of solitaire rules and undo/win mechanics.
+
+### 2. Interactive Curses TUI
+- Implemented entirely in Python standard library `curses` via `curses.wrapper(...)`.
+- Supports 16-color layouts (Red and Black suit differentiation, cyan labels, reverse video style highlighting for selections/focus).
+- Handles responsive window resizing (notifying users if the terminal height is under 24 lines or width is under 80 characters).
+- Supports intuitive cursor navigation using Arrow Keys or `WASD` across top piles (Stock, Waste, Foundations) and 7 Tableau columns.
+
+### 3. Draw-One Klondike Rules Implementation
+- **Stock & Waste**: Supports drawing cards face-up to waste, and recycling waste cards face-down back to the stock when empty.
+- **Tableau Columns**: Supports placing Kings on empty columns, building down columns with alternating colors and descending ranks, and moving multi-card face-up stacks.
+- **Auto-Reveal**: Automatically reveals the top-most card of a column when the card above it is moved.
+- **Foundations**: Correctly supports building piles up from Ace to King by matching suit.
+- **Undo History**: Implemented fully with deep-copied snapshot histories supporting unlimited multi-step undos.
+- **Win Detection**: Automatically triggers a victory screen when all 4 foundations reach a size of 13 cards.
+
+### 4. README documentation
+- Comprehensive documentation detailing:
+  - Installation and environment setup (no external requirements for run, standard `pytest` for tests).
+  - Terminal controls and grid navigation scheme.
+  - Commands for launching tests, the smoke test, and the game.
+
+### 5. Workspace Isolation
+- No generated files are outside the `solitaire-app/` directory, with the sole exception of the mandated `.ai/solitaire-fast-verify.md` and `status.json` at the workspace root.
+
+---
+
+## Conclusion
+The application is fully **demo-ready** and meets all requirements.
