+I have verified the card game logic and completed all the requirements.
+
+### Summary of Completed Work
+1. **Executed the Test Suite**: 
+   Ran the tests in `card-game-app` using `pytest`:
+   ```bash
+   cd card-game-app && python3 -m pytest tests/ -v
+   ```
+   All **21 tests** passed successfully, verifying that cards are correctly represented and all game mechanics are sound.
+
+2. **Verified Key Features**:
+   - **Move & Action Validation**: Confirmed that alternating colors, descending rank order, FreeCell occupancy, and Foundation sequence rules are strictly enforced. Calculated the supermove limit dynamically according to the standard FreeCell capacity formula: $\text{Max Movable} = (1 + F) \times 2^T$ (with proper $T-1$ adjustment for empty column target destinations).
+   - **Win & Loss Detection**: Verified that `is_won()` successfully identifies when all 52 cards are correctly stacked on their respective Foundation piles. Confirmed that `is_lost()` exhaustively checks all single-card and sequence-card transfer possibilities to identify deadlock states.
+   - **Undo & Redo System**: Confirmed that `save_state` creates a deep structural copy of the columns, free cells, and foundation piles prior to each move execution, supporting complete multi-level undo and redo branches seamlessly.
+   - **Auto-Homing Logic**: Validated the safe auto-homing heuristic, ensuring that card $R$ of a suit is automatically moved to its foundation only when opposite color cards of rank $R-1$ and same-color other suit cards of rank $R-2$ are in foundation.
+
+3. **Wrote Deliverables**:
+   - Created the detailed findings document at `.ai/verify_logic.md`.
+   - Updated the status document at `status.json` to reflect `outcome=succeeded`.
