Implemented high-fidelity ASCII card representation, rendering individual card ranks and suit symbols (`A♥`, `10♠`, etc.).\n - Handled empty foundation and free cell slot representation cleanly, maintaining accurate alignment.\n - Fully covered and verified these rendering helpers with robust unit tests.\n\n2. **Clean Curses TUI Layout & Interactivity (`tui.py` & `test_tui.py`)**:\n - Designed a symmetrical visual layout in an 80x24 space where every top slot (4 free cells and 4 foundations) maps perfectly to a Tableau column beneath it, making movement navigation extremely intuitive.\n - Handled color mappings dynamically for red (Hearts/Diamonds) and black (Spades/Clubs) cards.\n - Built an interactive selection system (`Space`/`Enter` to pick up/drop cards, `Escape` to cancel, and visual highlights using reverse video).\n - Supported multi-card selection/sequence moves, automatically checking and executing the maximum valid count under FreeCell rules by default, while allowing manual count adjustments using `[` and `]` or `-` and `+` keys.\n - Standardized hotkeys for **Undo** (`u`), **Redo** (`y`), **Restart** (`r` with same seed), **New Game** (`n` with new seed), and **Quit** (`q` with confirm dialog).\n - Abstracted screen logic from terminal sizes to prevent crashes or overflow and support terminal resizing safely.\n - Added robust headless unit tests validating the TUI controller's helpers (`find_longest_sequence`, `find_max_valid_count`, `get_current_pos`) without needing a live curses initialization.\n\n3. **Smoke Test Probe (`main.py`)**:\n - Enabled a non-interactive setup probe via `python3 main.py --smoke` that instantiates `GameState` with a deterministic seed, performs a series of mock movements, checks validations/win-states, and cleanly prints the status to stdout.\n\n4. **Validation Outcome**:\n -

**Win/loss condition:** Implemented and tested both `check_win()` and `check_loss()`. `check_loss()` correctly detects when the game has no legal moves remaining and is not yet won.\n - **Undo/Redo:** Reverts and reapplies both the primary action and any nested auto-homing steps.\n3. **Tests:** Added comprehensive test cases to `tests/test_domain.py` to cover `check_loss` under various conditions (not lost, won, and fully locked/lost).\n4. **Validation:** Ran all tests with `pytest` successfully, and confirmed that the `--smoke` test successfully initializes and validates the game.\n5. **Status File:** Wrote `status.json` with `\"outcome\": \"succeeded\"`.", + "last_stage": "impl_logic", + "last_response": "I have successfully completed the tasks:\n\n1. **Reviewed Specifications & Game Rules:** Read `.ai/card-game-spec.md` and verified the domain models (`Card`, `Deck`, `LocationType`, `Position`, `MoveRec" + }, + "notes": "Stage completed: impl_logic", + "usage": { + "input": { + "usage": { + "model": { + "provider": "gemini", + "model_id": "gemini-3.5-flash" + }, + "tokens": { + "input_tokens": 177020, + "output_tokens": 3075, + "reasoning_tokens": 5079, + "cache_read_tokens": 382131, + "cache_write_tokens": 0 + } + }, + "facts": { + "algorithm": "gemini", + "storage_segments": [] + } + }, + "total_usd_micros": 396235 + }, + "files_touched": [ + "/home/daytona/workspace/fabro/card-game-app/src/card_game_tui/domain.py", + "/home/daytona/workspace/fabro/card-game-app/tests/test_domain.py", + "/home/daytona/workspace/fabro/status.json" + ], + "timing": { + "wall_time_ms": 0, + "inference_time_ms": 75101, + "tool_time_ms": 19151, + "active_time_ms": 94252 + } + }, + "impl_ui": { + "status": "succeeded", + "context_updates": { + "response.impl_ui": "I have successfully built and verified the terminal-based FreeCell Solitaire game in Python!\n\n### Summary of Completed Work\n1. **ASCII Art Card Rendering (`render.py` & `test_render.py`)**:\n - Implemented high-fidelity ASCII card representation, rendering individual card ranks and suit symbols (`A♥`, `10♠`, etc.).\n - Handled empty foundation and free cell slot representation cleanly, maintaining accurate alignment.\n - Fully covered and verified these rendering helpers with robust unit tests.\n\n2. **Clean Curses TUI Layout & Interactivity (`tui.py` & `test_tui.py`)**:\n - Designed a symmetrical visual layout in an 80x24 space where every top slot (4 free cells and 4 foundations) maps perfectly to a Tableau column beneath it, making movement navigation extremely intuitive.\n - Handled color mappings dynamically for red (Hearts/Diamonds) and black (Spades/Clubs) cards.\n - Built an interactive selection system (`Space`/`Enter` to pick up/drop cards, `Escape` to cancel, and visual highlights using reverse video).\n - Supported multi-card selection/sequence moves, automatically checking and executing the maximum valid count under FreeCell rules by default, while allowing manual count adjustments using `[` and `]` or `-` and `+` keys.\n - Standardized hotkeys for **Undo** (`u`), **Redo** (`y`), **Restart** (`r` with same seed), **New Game** (`n` with new seed), and **Quit** (`q` with confirm dialog).\n - Abstracted screen logic from terminal sizes to prevent crashes or overflow and support terminal resizing safely.\n - Added robust headless unit tests validating the TUI controller's helpers (`find_longest_sequence`, `find_max_valid_count`, `get_current_pos`) without needing a live curses initialization.\n\n3. **Smoke Test Probe (`main.py`)**:\n - Enabled a non-interactive setup probe via `python3 main.py --smoke` that instantiates `GameState` with a deterministic seed, performs a series of mock movements, checks validations/win-states, and cleanly prints the status to stdout.\n\n4. **Validation Outcome**:\n -

Game Rules & Mechanics\n+\n+FreeCell is a solitaire card game played with a single standard 52-card deck. All cards are dealt face-up at the start.\n+\n+### 1.1 Table Layout\n+The game screen consists of three main areas:\n+- **Free Cells (4 cells)**: Temporary holding spaces. Each cell can hold at most one card of any suit and rank.\n+- **Foundations (4 piles)**: Destination piles built up by suit from Ace (rank 1) through King (rank 13). Winning the game requires placing all 52 cards here.\n+- **Tableau (8 columns)**: The main play area. Columns 1–4 are dealt 7 cards each; columns 5–8 are dealt 6 cards each.\n+\n+### 1.2 Movement Rules\n+- **Moving to a Free Cell**: Any single card can be moved to an empty Free Cell.\n+- **Moving to a Foundation**:\n+ - An **Ace** can be moved to an empty Foundation pile.\n+ - A card of rank $R$ and suit $S$ can be placed on a Foundation pile if the current top card of that pile is of suit $S$ and rank $R - 1$.\n+- **Moving to a Tableau Column**:\n+ - A single card of rank $R$ and color $C$ can be placed on top of a tableau card of rank $R+1$ and the *opposite* color (e.g., a Black 7 on a Red 8).\n+ - An empty tableau column can accept any single card.\n+- **Sequence Moves (Multiple Cards)**:\n+ - A sequence of cards that is properly ordered (descending ranks and alternating colors) can be moved together from one tableau column to another.\n+ - The maximum size of a sequence that can be moved depends on the number of empty Free Cells and empty Tableau columns available as temporary landing zones.\n+ - **Formula for Max Move Size**:\n+ $$\\text{Max Cards} = (1 + \\text{Empty Free Cells}) \\times 2^{\\text{Empty Tableau Columns}}$$\n+ *Exception*: If the destination column is an empty tableau column, that empty column does not count as \"empty\" in the exponent of the formula (as it is the final destination, not a temporary transit zone).\n+\n+### 1.3 Automatic Moves (\"Auto-Homing\")\n+To reduce tedious manual moves, the engine should automatically move cards to the Foundations if they can no longer be used as transition cards for lower-ranked cards. A card of rank $R$ and suit $S$ can safely be \"auto-homed\" to its Foundation if:\n+1. It is a legal move (it is on top of a tableau/freecell and matches $R-1$ of its foundation).\n+2. All cards of the *opposite color* with rank $R-1$ or lower have already been placed in the foundations. This ensures that no card still needs to be built on top of this card in the tableaus.\n+\n+---\n+\n+## 2. Core Domain Architecture (Non-UI)\n+\n+All domain logic must reside in classes that do not import or assume a `curses` environment.

Testing Strategy\n+\n+Maintaining 100% testability on rules guarantees that bugs are never hidden behind UI refresh issues.\n+\n+### 6.1 Unit Tests (Headless)\n+All game rule constraints must be tested inside a robust suite of unit tests (e.g. using `unittest` or `pytest`):\n+\n+- **Deck Verification**: Ensure 52 unique cards are present; verify that deterministic seeding generates identical layouts.\n+- **Move Validations**:\n+ - Valid and invalid moves to empty and occupied free cells.\n+ - Valid sequence building on Tableau (alternating color, consecutive ranks).\n+ - Multi-card tableau-to-tableau sequence validation obeying the formula: $(1 + \\text{empty cells}) \\times 2^{\\text{empty tableaus}}$.\n+ - Valid and invalid foundation building (Aces first, ordered ascending by suit).\n+- **Auto-Homing Logic**: Verify that cards are only auto-homed when all cards of the opposite color of smaller rank have already been homed.\n+- **Undo/Redo System**: Run a multi-step sequence, trigger undo, verify state completely matches initial configuration.\n+- **Win Detection**: Construct a state where all but 1 card is homed, verify final homing triggers winning state flag.\n+\n+### 6.2 Curses Integration Tests\n+For the UI layer, tests can mock the terminal dimensions and standard input keys using Python's `unittest.mock`:\n+- Mock `curses.getch` and verify the cursor coordinates state shifts correctly.\n+- Verify screen boundary logic prevents cursor overflow out of valid coordinates (e.g. going left of FreeCell column 0 or below the lowest card in a Tableau).\n+\n+---\n+\n+## 7. Implementation Milestones\n+\n+1. **Milestone 1**: Implement pure-domain `Card`, `Deck`, `Position`, and `GameState` engines.\n+2. **Milestone 2**: Write unit tests proving full game validation logic and automated auto-homing.\n+3. **Milestone 3**: Implement `--smoke` mode in CLI entrypoint and verify CI execution.\n+4. **Milestone 4**: Setup curses framework window structure, color palettes, and draw static cards.\n+5. **Milestone 5**: Implement interactive keyboard cursor, card selection mechanics, and execution hook.\n+6. **Milestone 6**: Complete Undo-stack integration and terminal resize layout adjustment handler.\ndiff --git a/.ai/verify_data.md b/.ai/verify_data.md\nnew file mode 100644\nindex 000000000..aa6dfcaf0\n--- /dev/null\n+++ b/.ai/verify_data.md\n@@ -0,0 +1,59 @@\n+# Data Structures and Core Game State Verification Findings\n+\n+## 1.

Core Game-State Types Defined\n+\n+The following models and enum types are defined in `src/card_game_tui/domain.py`:\n+\n+### Enums\n+- **`Suit`**: Enum representing the four suits: `HEARTS` (\"H\"), `DIAMONDS` (\"D\"), `CLUBS` (\"C\"), and `SPADES` (\"S\"). Includes color classification (`RED` or `BLACK`) and UTF-8 symbols (`♥`, `♦`, `♣`, `♠`).\n+- **`Rank`**: Enum representing ranks `ACE` (1) to `KING` (13) with appropriate alphanumeric labels (`A`, `J`, `Q`, `K`, or numeric string).\n+- **`LocationType`**: Enum classifying board areas: `TABLEAU`, `FREECELL`, and `FOUNDATION`.\n+\n+### Core Data Classes & Entities\n+- **`Card`**: Frozen dataclass containing `suit` and `rank`, with custom representation `[Rank][Suit]` (e.g., `A♥`, `10♠`).\n+- **`Position`**: Frozen dataclass packaging `LocationType` and `index` for explicit target and source identification during gameplay.\n+- **`MoveRecord`**: Stores move history containing `from_pos`, `to_pos`, moving cards list (`cards`), and a list of nested, cascaded `auto_moves` resulting from auto-homing.\n+- **`Deck`**: Builds a standard 52-card deck, supports deterministic random seeding, and deals cards into the 8 Tableau columns (four columns of 7 cards, four columns of 6 cards).\n+- **`GameState`**: Main orchestrator of the board. Holds state for:\n+ - 8 Tableau columns\n+ - 4 Free cells\n+ - Foundations mapped by Suit\n+ - Undo/Redo history stacks\n+\n+---\n+\n+## 3. Basic & Advanced Operations Verified\n+\n+### Move Validation and Rules Execution\n+- **Single Card Moves:** Correctly validates moving a card to free cells (if empty) and to foundations (Aces first, then sequential cards of the matching suit).\n+- **Tableau Placement rules:** Strictly enforces alternating colors and descending ranks (e.g., moving a Red 8 onto a Black 9).\n+- **Sequence/Multi-Card Moves:** Computes valid transit capacities based on the exact FreeCell Solitaire formula:\n+ $$\\text{Max Cards} = (1 + \\text{empty\\_freecells}) \\times 2^{\\text{transit\\_empty\\_tableaus}}$$\n+ Tested and verified that moves exceeding this threshold or violating sequential alternating order are rejected.\n+\n+### Cascade Auto-Homing\n+- Safely moves cards to foundations automatically after a successful player move.\n+- Avoids preemptive/unsafe auto-homing: a card is only auto-homed if its rank does not exceed $N+1$, where $N$ is the rank of the highest cards of the *opposite* color already placed in foundations. This prevents burying cards that might still be needed as Tableau anchors.\n+- Cascades until no further eligible cards can be home-bound.\n+\n+### Command History (Undo / Redo)\n+- Seamlessly reverts and reapplies moves.\n+- Accurately tracks nested auto-homed moves so that undoing a player's move rolls back the cascading auto-homing moves in precise reverse order.\n+\n+---\n+\n+## 4. Conclusion\n+The data model is fully complete, mathematically sound, robustly tested, and perfectly ready for consumption by the TUI layer.\ndiff --git a/.ai/verify_logic.md b/.ai/verify_logic.md\nnew file mode 100644\nindex 000000000..8ff2d891a\n--- /dev/null\n+++ b/.ai/verify_logic.md\n@@ -0,0 +1,81 @@\n+# Game Logic Verification Findings\n+\n+## 1. Overview and Command Execution\n+We have successfully run and verified the entire FreeCell Solitaire card game logic, move validation engine, win/loss detection, and undo/redo systems.\n+\n+The test suite was executed via the following command:\n+```bash\n+cd card-game-app && python3 -m pytest tests/ -v\n+```\n+\n+**Results:**\n+- **Pytest:** 16/16 tests passed successfully (100% pass rate).\n+- **Compilation Check:** Checked with `python3 -m py_compile main.py src/card_game_tui/*.py` – compiled with zero errors or warnings.\n+- **Smoke Test Check:** Checked with `python3 main.py --smoke` – completed successfully.\n+\n+---\n+\n+## 2. Core Game Logic Areas Verified\n+\n+### A. Move & Action Validation\n+The move validation engine in `GameState.validate_move` has been verified for all game scenarios:\n+- **Index boundaries:** Prevents invalid indices (e.g., tableaus outside 0-7, freecells/foundations outside 0-3).\n+- **Invalid sources:** Moving from a foundation is forbidden.\n+- **Single-card move constraints:**\n+ - **Free Cells:** Permits placement only if empty; prevents moves when already occupied.\n+ - **Foundations:** Enforces starting with an **Ace** and building up sequentially in ascending rank order (`Ace -> 2 -> ... -> King`) of the identical suit.\n+ - **Tableaus:** Validates build-down rules. A card can only be placed on a tableau column top card if it has the **opposite color** and is **one rank lower** (e.g., Red 8 onto Black 9).\n+- **Sequence/Multi-card moves:** \n+ - Validates sequence integrity of moving cards (alternating color, descending ranks).\n+ - Enforces the capacity constraint formula to calculate the maximum size of a legal sequence move:\n+ $$\\text{Max Cards} = (1 + \\text{empty\\_freecells}) \\times 2^{\\text{transit\\_empty\\_tableaus}}$$\n+ - Correctly adjusts `transit_empty_tableaus` when moving to an empty column (which cannot act as an intermediate transit space, i.e., `transit_empty_tableaus = max(0, empty_tableaus - 1)`).\n+\n+### B. Cascade Auto-Homing\n+- Automatically scans free cells and tableau column tops after each move to move eligible cards to their respective foundations.\n+- Implements **safe auto-homing**: A card of rank $R$ is only auto-homed if its rank does not exceed $N+1$, where $N$ is the length of the foundation pile of both **opposite color** suits. This prevents the user from accidentally locking/burying cards that are still needed for tableau building.\n+- Runs recursively until no more eligible cards can be safely auto-homed.\n+\n+### C. Win & Loss Detection\n+- **Win Detection (`check_win`):** Checks if all 52 cards are successfully stored in their foundations (13 cards in each of the 4 suit piles).\n+- **Loss Detection (`check_loss`):** Checks if there are absolutely no legal moves remaining. Evaluates:\n+ - Moving from any occupied freecell to any tableau column, empty freecell, or foundation pile.\n+ - Moving any valid-sized sequence of cards from any tableau column to any other tableau column, empty freecell, or foundation pile.\n+ - Returns `False` on start of game or if any move is possible, and correctly returns `True` when all moves are fully blocked.\n+\n+### D. Undo & Redo System\n+- Records moves using the `MoveRecord` model.\n+- **Nested Auto-Homing Rollback:** Captures all cascading auto-homing steps as nested records inside the primary player move.\n+- **Undo Operation:** Reverts the main player move and rolls back the cascading auto-homes in the **precise reverse order** of their execution to ensure absolute state consistency.\n+- **Redo Operation:** Correctly reapplies the undone player move followed by the exact nested auto-homing moves in their original forward order.\n+- **Stack Integrity:** Clears the redo stack whenever the player initiates a new manual move, following standard undo-redo history patterns.\n+\n+---\n+\n+## 3.

Implemented `Suit`, `Rank`, and `Card` representations.\n - Built the `Deck` class supporting deterministic seeding and standard 52-card dealing.\n - Designed the `Position` representation, covering tableau columns (0–7), free cells (0–3), and foundations (0–3).\n - Designed `MoveRecord` with full support for tracking regular moves and recursive `auto_moves` (auto-homing).\n - Implemented `GameState` managing all piles, validations (`validate_move`), executions (`execute_move`), full asymmetric/nested undo/redo, and win-state detection.\n - Implemented **Auto-Homing** rules exactly as specified: cards are moved automatically to foundations if and only if they are legal moves and all cards of the opposite color of lower ranks have already been homed.\n\n2. **Comprehensive Headless Unit Tests (`card-game-app/tests/test_domain.py`)**:\n - Built a comprehensive unit test suite covering:\n - Standard 52-card deck deal correctness.\n - Deterministic seeding verification.\n - Moves to and validations of Free Cells.\n - Moves to and validations of Foundations.\n - Single card move rules on the Tableau (descending rank, alternating colors).\n - Sequence/multi-card moves Tableau-to-Tableau obeying the rules & formula: `(1 + Empty Free Cells) * 2^(Empty Tableau Columns)` with destination empty-column exception.\n - Core Auto-Homing logic.\n - Perfect full undo/redo capabilities, including reverting auto-homing sequences.\n - Winning state detection.\n\n3. **Status Validation**:\n - All 13 unit tests passed flawlessly inside the Python testing framework.\n - The CLI non-interactive `--smoke` mode executes perfectly.\n - Wrote `status.json` with `outcome=succeeded`.", "response.verify_data": "I have completed the verification process for the card game data structures in FreeCell Solitaire. \n\n### Summary of Actions Taken:\n1. **Compilation & Tests Executed:** Ran tests and compiled python files successfully.\n - `python3 -m pytest tests/ -v` -> All 13 tests passed.\n - `python3 -m py_compile main.py src/card_game_tui/*.py` -> Compiled cleanly with zero syntax/import warnings.\n2. **Analysis of Core Types:** Inspected the data structures and validated:\n - **Enums:** `Suit`, `Rank`, and `LocationType`.\n - **Entities:** `Card` (frozen/immutable), `Position` (frozen), and `MoveRecord`.\n - **State Manager:** `GameState` containing Tableaus, FreeCells, Foundations, and full validation/execution of standard FreeCell logic.\n3. **Advanced Mechanics Verified:**\n - Alternate-color and descending-rank move validations.\n - Multi-card sequential moves with correct capacity limits based on empty free cells and empty tableaus.\n - Smart, cascading auto-homing that avoids locking cards required for lower ranks of opposing colors.\n - Linear undo/redo stack managing primary moves alongside automatic cascades.\n4. **Output Generation:**\n - Detailed findings recorded in `.ai/verify_data.md`.\n - `status.json` updated with `\"outcome\": \"succeeded\"`.", "internal.retry_count.impl_data": 0, -

**Initial setup/deal:** Fully handled inside `Deck` and `GameState` constructor, dealing 52 unique cards deterministically.\n - **Move/action validation:** Fully covered for tableau, free cell, and foundation moves, including proper transit and capacity calculations based on empty free cells/tableaus.\n - **Auto-complete helper actions:** Standard auto-homing behavior is implemented, moving eligible cards to foundations automatically and cleanly nesting them in `MoveRecord` so they are fully undoable/redoable.\n - **Win/loss condition:** Implemented and tested both `check_win()` and `check_loss()`. `check_loss()` correctly detects when the game has no legal moves remaining and is not yet won.\n - **Undo/Redo:** Reverts and reapplies both the primary action and any nested auto-homing steps.\n3. **Tests:** Added comprehensive test cases to `tests/test_domain.py` to cover `check_loss` under various conditions (not lost, won, and fully locked/lost).\n4. **Validation:** Ran all tests with `pytest` successfully, and confirmed that the `--smoke` test successfully initializes and validates the game.\n5. **Status File:** Wrote `status.json` with `\"outcome\": \"succeeded\"`.", "graph.default_max_retries": "3", "response.verify_setup": "I have successfully verified the setup for the card game app.\n\n### Verified Checklist:\n1. **`card-game-app/pyproject.toml` exists:** Verified.\n2. **`card-game-app/main.py` exists:** Verified.\n3. **`card-game-app/src/card_game_tui` exists:** Verified.\n4. **Python files compile:** Verified by executing `cd card-game-app && python3 -m py_compile main.py src/card_game_tui/*.py` (which completed with exit code `0`).\n\nFindings have been written to `.ai/verify_setup.md` and `status.json` has been updated with `\"outcome\": \"succeeded\"` at the workspace root.", -

Game Rules & Mechanics ++ ++FreeCell is a solitaire card game played with a single standard 52-card deck. All cards are dealt face-up at the start. ++ ++### 1.1 Table Layout ++The game screen consists of three main areas: ++- **Free Cells (4 cells)**: Temporary holding spaces. Each cell can hold at most one card of any suit and rank. ++- **Foundations (4 piles)**: Destination piles built up by suit from Ace (rank 1) through King (rank 13). Winning the game requires placing all 52 cards here. ++- **Tableau (8 columns)**: The main play area. Columns 1–4 are dealt 7 cards each; columns 5–8 are dealt 6 cards each. ++ ++### 1.2 Movement Rules ++- **Moving to a Free Cell**: Any single card can be moved to an empty Free Cell. ++- **Moving to a Foundation**: ++ - An **Ace** can be moved to an empty Foundation pile. ++ - A card of rank $R$ and suit $S$ can be placed on a Foundation pile if the current top card of that pile is of suit $S$ and rank $R - 1$. ++- **Moving to a Tableau Column**: ++ - A single card of rank $R$ and color $C$ can be placed on top of a tableau card of rank $R+1$ and the *opposite* color (e.g., a Black 7 on a Red 8). ++ - An empty tableau column can accept any single card. ++- **Sequence Moves (Multiple Cards)**: ++ - A sequence of cards that is properly ordered (descending ranks and alternating colors) can be moved together from one tableau column to another. ++ - The maximum size of a sequence that can be moved depends on the number of empty Free Cells and empty Tableau columns available as temporary landing zones. ++ - **Formula for Max Move Size**: ++ $$\text{Max Cards} = (1 + \text{Empty Free Cells}) \times 2^{\text{Empty Tableau Columns}}$$ ++ *Exception*: If the destination column is an empty tableau column, that empty column does not count as "empty" in the exponent of the formula (as it is the final destination, not a temporary transit zone). ++ ++### 1.3 Automatic Moves ("Auto-Homing") ++To reduce tedious manual moves, the engine should automatically move cards to the Foundations if they can no longer be used as transition cards for lower-ranked cards. A card of rank $R$ and suit $S$ can safely be "auto-homed" to its Foundation if: ++1. It is a legal move (it is on top of a tableau/freecell and matches $R-1$ of its foundation). ++2. All cards of the *opposite color* with rank $R-1$ or lower have already been placed in the foundations. This ensures that no card still needs to be built on top of this card in the tableaus. ++ ++--- ++ ++## 2. Core Domain Architecture (Non-UI) ++ ++All domain logic must reside in classes that do not import or assume a `curses` environment. This ensures unit tests can run in headless CI environments. ++ ++``` +++-------------------------------------------------------------+ ++| Domain Model | ++| | ++| +----------------+ +---------------+ | ++| | Card |---> | Deck | | ++| +----------------+ +---------------+ | ++| | | ++| v | ++| +----------------+ | ++| | GameState | <--- Handles validation, moves, undo | ++| +----------------+ | +++-------------------------------------------------------------+ ++``` ++ ++### 2.1 Domain Types & Data Structures ++ ++#### Card Representation ++```python ++from dataclasses import dataclass ++from enum import Enum, auto ++ ++class Suit(Enum): ++ HEARTS = "H" ++ DIAMONDS = "D" ++ CLUBS = "C" ++ SPADES = "S" ++ ++ @property ++ def color(self) -> str: ++ return "RED" if self in (Suit.HEARTS, Suit.DIAMONDS) else "BLACK" ++ ++ @property ++ def symbol(self) -> str: ++ # Unicode symbols for attractive rendering ++ return { ++ Suit.HEARTS: "♥", ++ Suit.DIAMONDS: "♦", ++ Suit.CLUBS: "♣", ++ Suit.SPADES: "♠" ++ }[self] ++ ++class Rank(Enum): ++ ACE = 1 ++ TWO = 2 ++ THREE = 3 ++ FOUR = 4 ++ FIVE = 5 ++ SIX = 6 ++ SEVEN = 7 ++ EIGHT = 8 ++ NINE = 9 ++ TEN = 10 ++ JACK = 11 ++ QUEEN = 12 ++ KING = 13 ++ ++ @property ++ def label(self) -> str: ++ if self.value == 1: return "A" ++ if self.value == 11: return "J" ++ if self.value == 12: return "Q" ++ if self.value == 13: return "K" ++ return str(self.value) ++ ++@dataclass(frozen=True) ++class Card: ++ suit: Suit ++ rank: Rank ++ ++ def __repr__(self) -> str: ++ return f"{self.rank.label}{self.suit.symbol}" ++``` ++ ++#### Deck & Setup ++```python ++import random ++from typing import List ++ ++class Deck: ++ def __init__(self, seed: int = None): ++ self.cards = [Card(suit, rank) for suit in Suit for rank in Rank] ++ if seed is not None: ++ random.seed(seed) ++ random.shuffle(self.cards) ++ ++ def deal(self) -> List[List[Card]]: ++ """Deals 52 cards into 8 columns.""" ++ tableaus: List[List[Card]] = [[] for _ in range(8)] ++ for i, card in enumerate(self.cards): ++ tableaus[i % 8].append(card) ++ return tableaus ++``` ++ ++#### Move Representation ++To support an robust Undo/Redo stack, each move is captured as a detailed state transition: ++```python ++from typing import Union ++ ++class LocationType(Enum): ++ TABLEAU = auto() ++ FREECELL = auto() ++ FOUNDATION = auto() ++ ++@dataclass(frozen=True) ++class Position: ++ type: LocationType ++ index: int # 0-7 for Tableau, 0-3 for FreeCell, 0-3 for Foundation ++ ++@dataclass ++class MoveRecord: ++ from_pos: Position ++ to_pos: Position ++ cards: List[Card] # Captured for single or sequence moves ++ auto_moves: List['MoveRecord'] = None # Nested moves triggered by auto-homing ++``` ++ ++### 2.2 Core Engine (`GameState`) ++The state engine encapsulates all state, mutations, validation, and history. ++ ++```python ++class GameState: ++ def __init__(self, seed: int = None): ++ self.tableaus: List[List[Card]] = Deck(seed).deal() ++ self.freecells: List[Union[Card, None]] = [None] * 4 ++ self.foundations: dict[Suit, List[Card]] = {suit: [] for suit in Suit} ++ self.undo_stack: List[MoveRecord] = [] ++ self.redo_stack: List[MoveRecord] = [] ++ ++ def get_card_at(self, position: Position) -> Union[Card, None]: ++ if position.type == LocationType.FREECELL: ++ return self.freecells[position.index] ++ elif position.type == LocationType.FOUNDATION: ++ pile = self.foundations[list(Suit)[position.index]] ++ return pile[-1] if pile else None ++ elif position.type == LocationType.TABLEAU: ++ col = self.tableaus[position.index] ++ return col[-1] if col else None ++ return None ++ ++ def validate_move(self, from_pos: Position, to_pos: Position, count: int = 1) -> bool: ++ """ ++ Calculates whether moving 'count' cards from from_pos to to_pos is legal. ++ """ ++ # 1.

Non-Interactive Smoke Mode ++ ++To ensure the CLI can be verified programmatically without invoking an interactive full-screen curses environment, the application must support a non-interactive setup probe via `--smoke`: ++ ++```bash ++python3 main.py --smoke ++``` ++ ++### 5.1 Smoke Mode Requirements: ++- Must not call `curses.initscr()`, `curses.wrapper()`, or perform terminal modifications. ++- Must initialize the domain engine (`GameState`) with a deterministic test seed. ++- Must execute a tiny mock transaction sequence (e.g., attempt 2 valid moves and 1 invalid move, validating assertion outcomes). ++- Must print a plain-text confirmation of the test result to stdout. ++- Must exit with status code `0` on success, or a non-zero exit code if an import or validation error occurs. ++ ++--- ++ ++## 6. Testing Strategy ++ ++Maintaining 100% testability on rules guarantees that bugs are never hidden behind UI refresh issues. ++ ++### 6.1 Unit Tests (Headless) ++All game rule constraints must be tested inside a robust suite of unit tests (e.g. using `unittest` or `pytest`): ++ ++- **Deck Verification**: Ensure 52 unique cards are present; verify that deterministic seeding generates identical layouts. ++- **Move Validations**: ++ - Valid and invalid moves to empty and occupied free cells. ++ - Valid sequence building on Tableau (alternating color, consecutive ranks). ++ - Multi-card tableau-to-tableau sequence validation obeying the formula: $(1 + \text{empty cells}) \times 2^{\text{empty tableaus}}$. ++ - Valid and invalid foundation building (Aces first, ordered ascending by suit). ++- **Auto-Homing Logic**: Verify that cards are only auto-homed when all cards of the opposite color of smaller rank have already been homed. ++- **Undo/Redo System**: Run a multi-step sequence, trigger undo, verify state completely matches initial configuration. ++- **Win Detection**: Construct a state where all but 1 card is homed, verify final homing triggers winning state flag. ++ ++### 6.2 Curses Integration Tests ++For the UI layer, tests can mock the terminal dimensions and standard input keys using Python's `unittest.mock`: ++- Mock `curses.getch` and verify the cursor coordinates state shifts correctly. ++- Verify screen boundary logic prevents cursor overflow out of valid coordinates (e.g. going left of FreeCell column 0 or below the lowest card in a Tableau). ++ ++--- ++ ++## 7. Implementation Milestones ++ ++1. **Milestone 1**: Implement pure-domain `Card`, `Deck`, `Position`, and `GameState` engines. ++2. **Milestone 2**: Write unit tests proving full game validation logic and automated auto-homing. ++3. **Milestone 3**: Implement `--smoke` mode in CLI entrypoint and verify CI execution. ++4. **Milestone 4**: Setup curses framework window structure, color palettes, and draw static cards. ++5. **Milestone 5**: Implement interactive keyboard cursor, card selection mechanics, and execution hook. ++6. **Milestone 6**: Complete Undo-stack integration and terminal resize layout adjustment handler. +diff --git a/.ai/verify_data.md b/.ai/verify_data.md +new file mode 100644 +index 000000000..aa6dfcaf0 +--- /dev/null ++++ b/.ai/verify_data.md +@@ -0,0 +1,59 @@ ++# Data Structures and Core Game State Verification Findings ++ ++## 1.

Core Game-State Types Defined ++ ++The following models and enum types are defined in `src/card_game_tui/domain.py`: ++ ++### Enums ++- **`Suit`**: Enum representing the four suits: `HEARTS` ("H"), `DIAMONDS` ("D"), `CLUBS` ("C"), and `SPADES` ("S"). Includes color classification (`RED` or `BLACK`) and UTF-8 symbols (`♥`, `♦`, `♣`, `♠`). ++- **`Rank`**: Enum representing ranks `ACE` (1) to `KING` (13) with appropriate alphanumeric labels (`A`, `J`, `Q`, `K`, or numeric string). ++- **`LocationType`**: Enum classifying board areas: `TABLEAU`, `FREECELL`, and `FOUNDATION`. ++ ++### Core Data Classes & Entities ++- **`Card`**: Frozen dataclass containing `suit` and `rank`, with custom representation `[Rank][Suit]` (e.g., `A♥`, `10♠`). ++- **`Position`**: Frozen dataclass packaging `LocationType` and `index` for explicit target and source identification during gameplay. ++- **`MoveRecord`**: Stores move history containing `from_pos`, `to_pos`, moving cards list (`cards`), and a list of nested, cascaded `auto_moves` resulting from auto-homing. ++- **`Deck`**: Builds a standard 52-card deck, supports deterministic random seeding, and deals cards into the 8 Tableau columns (four columns of 7 cards, four columns of 6 cards). ++- **`GameState`**: Main orchestrator of the board. Holds state for: ++ - 8 Tableau columns ++ - 4 Free cells ++ - Foundations mapped by Suit ++ - Undo/Redo history stacks ++ ++--- ++ ++## 3. Basic & Advanced Operations Verified ++ ++### Move Validation and Rules Execution ++- **Single Card Moves:** Correctly validates moving a card to free cells (if empty) and to foundations (Aces first, then sequential cards of the matching suit). ++- **Tableau Placement rules:** Strictly enforces alternating colors and descending ranks (e.g., moving a Red 8 onto a Black 9). ++- **Sequence/Multi-Card Moves:** Computes valid transit capacities based on the exact FreeCell Solitaire formula: ++ $$\text{Max Cards} = (1 + \text{empty\_freecells}) \times 2^{\text{transit\_empty\_tableaus}}$$ ++ Tested and verified that moves exceeding this threshold or violating sequential alternating order are rejected. ++ ++### Cascade Auto-Homing ++- Safely moves cards to foundations automatically after a successful player move. ++- Avoids preemptive/unsafe auto-homing: a card is only auto-homed if its rank does not exceed $N+1$, where $N$ is the rank of the highest cards of the *opposite* color already placed in foundations. This prevents burying cards that might still be needed as Tableau anchors. ++- Cascades until no further eligible cards can be home-bound. ++ ++### Command History (Undo / Redo) ++- Seamlessly reverts and reapplies moves. ++- Accurately tracks nested auto-homed moves so that undoing a player's move rolls back the cascading auto-homing moves in precise reverse order. ++ ++--- ++ ++## 4.

Core Game Logic Areas Verified ++ ++### A. Move & Action Validation ++The move validation engine in `GameState.validate_move` has been verified for all game scenarios: ++- **Index boundaries:** Prevents invalid indices (e.g., tableaus outside 0-7, freecells/foundations outside 0-3). ++- **Invalid sources:** Moving from a foundation is forbidden. ++- **Single-card move constraints:** ++ - **Free Cells:** Permits placement only if empty; prevents moves when already occupied. ++ - **Foundations:** Enforces starting with an **Ace** and building up sequentially in ascending rank order (`Ace -> 2 -> ... -> King`) of the identical suit. ++ - **Tableaus:** Validates build-down rules. A card can only be placed on a tableau column top card if it has the **opposite color** and is **one rank lower** (e.g., Red 8 onto Black 9). ++- **Sequence/Multi-card moves:** ++ - Validates sequence integrity of moving cards (alternating color, descending ranks). ++ - Enforces the capacity constraint formula to calculate the maximum size of a legal sequence move: ++ $$\text{Max Cards} = (1 + \text{empty\_freecells}) \times 2^{\text{transit\_empty\_tableaus}}$$ ++ - Correctly adjusts `transit_empty_tableaus` when moving to an empty column (which cannot act as an intermediate transit space, i.e., `transit_empty_tableaus = max(0, empty_tableaus - 1)`). ++ ++### B. Cascade Auto-Homing ++- Automatically scans free cells and tableau column tops after each move to move eligible cards to their respective foundations. ++- Implements **safe auto-homing**: A card of rank $R$ is only auto-homed if its rank does not exceed $N+1$, where $N$ is the length of the foundation pile of both **opposite color** suits. This prevents the user from accidentally locking/burying cards that are still needed for tableau building. ++- Runs recursively until no more eligible cards can be safely auto-homed. ++ ++### C. Win & Loss Detection ++- **Win Detection (`check_win`):** Checks if all 52 cards are successfully stored in their foundations (13 cards in each of the 4 suit piles). ++- **Loss Detection (`check_loss`):** Checks if there are absolutely no legal moves remaining. Evaluates: ++ - Moving from any occupied freecell to any tableau column, empty freecell, or foundation pile. ++ - Moving any valid-sized sequence of cards from any tableau column to any other tableau column, empty freecell, or foundation pile. ++ - Returns `False` on start of game or if any move is possible, and correctly returns `True` when all moves are fully blocked. ++ ++### D. Undo & Redo System ++- Records moves using the `MoveRecord` model. ++- **Nested Auto-Homing Rollback:** Captures all cascading auto-homing steps as nested records inside the primary player move. ++- **Undo Operation:** Reverts the main player move and rolls back the cascading auto-homes in the **precise reverse order** of their execution to ensure absolute state consistency. ++- **Redo Operation:** Correctly reapplies the undone player move followed by the exact nested auto-homing moves in their original forward order. ++- **Stack Integrity:** Clears the redo stack whenever the player initiates a new manual move, following standard undo-redo history patterns. ++ ++--- ++ ++## 3. Verified Scenarios and Test Coverage Matrix ++ ++The following test suites in `tests/test_domain.py` verify these domains: ++ ++| Test Name | Verifies | Status | ++| :--- | :--- | :--- | ++| `test_deck_deals_52_cards` | Deck creation has 52 cards | Pass | ++| `test_game_state_initialization` | Tableau dealing heights (four of 7, four of 6) | Pass | ++| `test_get_card_at` | Cards can be inspected accurately across tableaus, freecells, and foundations | Pass | ++| `test_deck_deterministic_seeding` | Deterministic shuffle given a seed | Pass | ++| `test_moves_to_free_cells` | Standard single-card moves and boundary conditions on free cells | Pass | ++| `test_moves_to_foundations` | Ascending rank sequences and suit checks on foundations | Pass | ++| `test_moves_to_tableau_single_card` | Alternating color and descending rank builds on tableau | Pass | ++| `test_sequence_moves_tableau_to_tableau` | Moving sequences and standard capacity calculation checks | Pass | ++| `test_sequence_moves_to_empty_tableau` | Capacity calculation adjustement when moving to an empty tableau column | Pass | ++| `test_auto_homing_logic` | Cascade moves & safe auto-homing constraints relative to opposite suits | Pass | ++| `test_undo_redo_system` | Basic rollback and forward operations on manual moves | Pass | ++| `test_undo_with_auto_homing` | Rolling back complex cascade sequences in precise reverse order | Pass | ++| `test_win_detection` | Accurate identification when all 52 cards are homed | Pass | ++| `test_check_loss_not_lost` | Returns false when game is solvable/moves exist | Pass | ++| `test_check_loss_won` | Returns false on won states | Pass | ++| `test_check_loss_is_lost` | Returns true when game is completely locked with no moves | Pass | ++ ++--- ++ ++## 4.
