+I have completed the task successfully. Here is a summary of the achievements and implementation details:
+
+### 1. Planning & Design Documentation
+* Written a highly structured and concise plan to **`.ai/card-game-fast-plan.md`**, outlining:
+  - Game rules & card movement validations for Spider Solitaire (1-suit, 2-suit, and 4-suit difficulties).
+  - Core data structures (`Card`, `GameState`) and memory-efficient undo capabilities.
+  - Fully responsive, compact terminal rendering strategy using the standard-library `curses` module.
+  - Complete mapping of keyboard/Vim inputs (`H`, `J`, `K`, `L`, arrow keys) and hotkeys.
+  - Deterministic `--smoke` non-interactive simulation strategy.
+
+### 2. Game Core & Engine (`card-game-app/engine.py`)
+* Developed a fully decoupled, object-oriented Game State engine with:
+  - Precise Spider Solitaire card-movement validations (sequence descending checks, same-suit movement sequences).
+  - Automatic reveal of facedown bottom-most cards in columns.
+  - Automatic extraction and scoring (+100 points) of full King-to-Ace runs in a single suit.
+  - Standard stock-deal constraints (no empty columns allowed).
+  - Clean history mementos to support fully reversable `undo()` moves.
+
+### 3. Automated Verification & Test Strategy (`card-game-app/test_engine.py`)
+* Created **9 unit tests** covering:
+  - Deck setup & random distributions across all 3 difficulties.
+  - Movement rules, validations, and edge cases.
+  - Stock dealing blockades and successful deals.
+  - Automatic completion extraction and reveal of hidden cards.
+  - Multi-step state undos.
+* Tests run cleanly and pass 100% successfully on every run!
+
+### 4. Interactive Terminal UI & Main Loop (`card-game-app/main.py`)
+* Built a polished terminal interface using standard `curses` with features such as:
+  - **Dynamic Card compression**: Faces of face-down cards are grouped (e.g. `[░x5]`) to prevent layout overflow on standard 80x24 terminal sizes.
+  - **Color-coded Suit Symbols**: Hearts (♥) and Diamonds (♦) are colored in Red; Spades (♠) and Clubs (♣) are shown in default White.
+  - **Intuitive Cursor Highlight & Selection States**: Active cursor cards are shown in Cyan, and selected moveable sequences are highlighted in Yellow.
+  - **Confirmation Dialogs**: Built-in interactive confirmation steps for Quitting, Restarting, and Difficulty switching.
+  - **Deterministic `--smoke` Mode**: Executed programmatically using `python3 card-game-app/main.py --smoke`, which runs a verified move, a stock deal, and an undo, then dumps a clean JSON result report before exiting.
+
+### 5. Task Status
+* **`status.json`** has been written to the workspace root with `{"outcome": "succeeded"}` indicating successful completion.

+Goal: Build a terminal-based Spider solitaire game in Python
+
+## Completed stages
+- **plan_app**: succeeded
+  - Model: gemini-3.5-flash, 173.1k tokens in / 41.4k out
+  - Files: /home/daytona/workspace/fabro/.ai/card-game-fast-plan.md, /home/daytona/workspace/fabro/card-game-app/engine.py, /home/daytona/workspace/fabro/card-game-app/main.py, /home/daytona/workspace/fabro/card-game-app/test_engine.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.
