+# 2024-12-18 - Fix Initial Draw Logic
+
+## Problem
+The user reported that upon entering the game and being prompted to Mulligan, their hand was empty. This prevented them from making an informed decision.
+
+## Root Cause
+The `GameManager` initialized the game state with `step: 'mulligan'`, but the `RulesEngine` was never invoked to perform the initial turn-based actions (specifically the initial draw). The cards were added to the `library` zone, but no logic moved them to the `hand` zone before the game start update was sent to the client.
+
+## Solution
+1.  **Updated `RulesEngine.ts`**: Added a public `startGame()` method that logs the start and calls `performTurnBasedActions()`. `performTurnBasedActions()` already contained the logic to draw 7 cards if the step is 'mulligan' and the hand is empty.
+2.  **Updated `server/index.ts`**: Modified all game initialization flows (`player_ready`, `start_solo_test`, `start_game`, and the global timer loop) to instantiate a `RulesEngine` and call `startGame()` immediately after populating the deck cards.
+
+## outcome
+When a game starts, the server now proactively triggers the initial draw logic. Clients receive the initial game state with 7 cards in hand, allowing the Mulligan UI to display the cards correctly.

+# 2024-12-18 - Implement Manual Card Draw
+
+## Problem
+The user reported that clicking on the library or using the "Draw Card" context menu option had no effect. The frontend was correctly emitting the `DRAW_CARD` action (via `game_action` channel/event), but the `GameManager` (which handles manual/legacy actions) had no case handler for it, causing the action to be ignored.
+
+## Root Cause
+1.  **Missing Handler**: The `GameManager.handleAction` switch statement lacked a `case 'DRAW_CARD'`.
+2.  **Access Control**: The `RulesEngine.drawCard` method was `private`, preventing external invocation even if the handler existed.
+
+## Solution
+1.  **Made `drawCard` Public**: Updated `RulesEngine.ts` to change `drawCard` visibility from `private` to `public`.
+2.  **Added Handler**: Updated `GameManager.ts` to include a `case 'DRAW_CARD'` in `handleAction`. This handler instantiates a `RulesEngine` for the current game and calls `engine.drawCard(actorId)`.
+
+## Outcome
+Users can now manually draw cards from their library interactions (click or context menu) during gameplay.

+# 2024-12-18 - Fix Actions Post-Mulligan
+
+## Problem
+After the Mulligan phase, users reported "no actions working". The Smart Button and other strict interactions (Priority passing) were failing.
+
+## Root Cause
+1.  **Frontend Emission**: The `SmartButton` in `GameView.tsx` and the `RadialMenu` for mana were emitting legacy `type` strings (e.g. `PASS_PRIORITY` or `ADD_MANA` directly), or wrapped incorrectly. Specifically, `SmartButton` was correctly wrapping in `game_strict_action` but likely the state alignment was off.
+2.  **Radial Menu**: Was emitting `ADD_MANA` as a legacy `game_action`. Legacy `GameManager` (before my fix in previous step) handled basic actions, but `ADD_MANA` is a strict engine concept. `GameManager.handleAction` (legacy) did not handle it. We needed to target `game_strict_action` or add a handler.
+3.  **State Reset**: The engine's transition from Mulligan -> Untap -> Upkeep -> Draw -> Main1 relies on `resetPriority` correctly assigning priority to the Active Player. If this flow is interrupted or if the client UI doesn't realize it has priority (due to `priorityPlayerId` mismatch), the Smart Button disables itself.
+
+## Solution
+1.  **Strict Action Alignment**: Updated `GameView.tsx` to ensure `RadialMenu` (Mana) emits `game_strict_action`.
+2.  **Handling**: (Previous Step) Added `DRAW_CARD` support.
+3.  **Smart Button Checking**: Confirmed Smart Button emits `type` which `GameView` wraps in `action`. This matches `socket.on('game_strict_action', { action })`. This path is correct.
+
+## Verification
+The flow "Mulligan -> Advanced Step (Mulligan Ends) -> Untap (Auto) -> Upkeep -> Reset Priority (Active Player)" seems logic-sound in `RulesEngine`. With the frontend now targeting the strict endpoint for Mana/Priority, and the legacy handler updated for Draw, the loop should be closed.
+
+## Remaining Risk
+If `resetPriority` sets `priorityPlayerId` to a player ID that doesn't match the client's `currentPlayerId` (e.g. Turn 1 Order), the button will stay gray/disabled. This is Rules Correct (you can't act if not your priority), but UI feedback (telling *whose* turn/priority it is) is crucial. The existing `PhaseStrip` or `SmartButton` should indicate this.

+# 2024-12-18 - Parse Card Data Robustness
+
+## Problem
+The user reported issues with "placing cards onto the battlefield". Specifically, this manifested in two likely ways:
+1.  Creature cards fading away instantly (dying to State-Based Actions) because their Power/Toughness was defaulted to 0/0.
+2.  Cards resolving to the Graveyard instead of Battlefield because the `RulesEngine` failed to identify them as Permanents (empty `types` array), defaulting to Instant/Sorcery behavior.
+
+## Root Cause
+1.  **Missing P/T Passing**: The `server/index.ts` file was constructing the initial game state from deck cards but failing to explicitly copy `power` and `toughness` properties.
+2.  **Missing Type Parsing**: The `GameManager` (and `index.ts`) relied on `typeLine` string but did not parse it into the `types` array which the `RulesEngine` strictly checks for `isPermanent` logic and invalid aura validation.
+
+## Solution
+1.  **Updated `GameManager.ts`**: Added robust parsing logic in `addCardToGame`. If `card.types` is empty, it now parses `card.typeLine` (e.g. splitting "Legendary Creature — Human") to populate `types`, `supertypes`, and `subtypes` arrays.
+2.  **Updated `server/index.ts`**: Modified all game initialization flows to explicitly pass `power` and `toughness` from the source data to `gameManager.addCardToGame`.
+
+## Outcome
+Cards added to the game now have correct type metadata and base stats.
+-   Creatures resolve to the battlefield correctly (identified as Permanents).
+-   Creatures stay on the battlefield (Toughness > 0 prevents SBA death).

+# 2024-12-18 - Fix GameManager logging TypeError
+
+## Problem
+The user reported a server crash with `TypeError: Cannot read properties of undefined (reading 'type')`. This occurred in the `GameManager.handleStrictAction` catch block when attempting to log `action.type` during an error condition, implying that `action` itself might be undefined or causing access issues in that context, or the error handling was too aggressive on a malformed payload.
+
+## Root Cause
+The `catch(e)` block blindly accessed `action.type` to log the rule violation context. If `action` was null or undefined (which could happen if validation failed earlier or weird payloads arrived), this access threw the new error. Although `handleStrictAction` generally checks inputs, robust error logging should not crash.
+
+## Solution
+Updated the catch block in `src/server/managers/GameManager.ts` to use optional chaining `action?.type` and provide a fallback string `'UNKNOWN'`.
+
+## Outcome
+Server will now safely log "Rule Violation [UNKNOWN]" instead of crashing if the action payload is malformed during an error scenario.

+# 2024-12-18 - Fix Strict Action Payload Construction
+
+## Problem
+The user reported a server crash/error: `Rule Violation [UNKNOWN]: Cannot read properties of undefined (reading 'type')`.
+This occurred when resolving lands or casting spells. The error log "UNKNOWN" indicated the server received a null/undefined `action` object within the `game_strict_action` event payload.
+The server expects `socket.emit('game_strict_action', { action: { type: '...' } })`.
+The client was emitting `socket.emit('game_strict_action', { type: '...' })` (missing the `action` wrapper).
+
+## Root Cause
+When refactoring for the Strict Actions, the frontend calls for `handleZoneDrop` (Battlefield), `handleCardDrop`, and `handlePlayerDrop` were updated to emit the new event name `game_strict_action`, but the payload structure was not updated to wrap the data in an `{ action: ... }` object as expected by `server/index.ts`.
+
+## Solution
+Updated `GameView.tsx` in three locations (`handleZoneDrop`, `handleCardDrop`, `handlePlayerDrop`) to correctly wrap the payload:
+```typescript
+socketService.socket.emit('game_strict_action', {
+  action: {
+    type: '...',
+    ...
+  }
+});
+```
+
+## Outcome
+Client strict actions now match the server's expected payload structure. Actions like playing lands or casting spells should now execute defined logic instead of crashing or being treated as unknown.

+# 2024-12-18 - Fix Combat Skip Logic
+
+## Problem
+The user could not "Skip Combat" (Move past Declare Attackers). The button action `DECLARE_ATTACKERS` with 0 attackers was working server-side (resetting priority to AP), but the client UI (`SmartButton`) remained stuck on "Skip Combat". This created a loop where the user clicked, action processed, priority returned, and the UI still asked them to declare attackers.
+
+## Root Cause
+The `SmartButton` logic relied solely on `gameState.step === 'declare_attackers'`. It did not differentiate between "Need to Declare" (Start of Step) and "After Declaration / Priority Window" (Middle of Step).
+Strict Rules State did not have a flag to indicate if the Turn-Based Action of declaring attackers had already occurred for the current step.
+
+## Solution
+1.  **Updated `Types`**: Added optional `attackersDeclared` (and `blockersDeclared`) boolean flags to `StrictGameState` (Server + Client).
+2.  **Updated `RulesEngine`**: In `declareAttackers()`, set `attackersDeclared = true`. In `cleanupStep()`, reset these flags to `false`.
+3.  **Updated `SmartButton`**: Added a check. If `step === 'declare_attackers'` AND `attackersDeclared` is true, display "Pass (to Blockers)" with `PASS_PRIORITY` action instead of "Skip Combat" / `DECLARE_ATTACKERS`.
+
+## Outcome
+When a user clicks "Skip Combat" (declares 0 attackers), the server updates the state flag. The UI then updates to show a "Pass" button, allowing the user to proceed to the next step.

+# 2024-12-18 - Fix Empty Combat Step Skipping
+
+## Problem
+When a player declares 0 attackers (Skip Combat), the game correctly advances from `declare_attackers` but then proceeds to `declare_blockers` instead of skipping to the end of combat. This forces the (non-existent) defending player to declare blockers against nothing, or the active player to wait through irrelevant priority passes.
+
+## Root Cause
+The `RulesEngine.advanceStep()` method strictly followed the standard phase/step structure defined in `server/game/RulesEngine.ts`. It lacked the logic to implement Rule 508.8, which states that if no attackers are declared, the Declare Blockers and Combat Damage steps are skipped.
+
+## Solution
+Modified `RulesEngine.advanceStep()` to check for attackers before transitioning steps.
+If the current phase is `combat` and the next projected step is `declare_blockers`, it checks if any cards have the `attacking` property.
+If `attackers.length === 0`, it overrides `nextStep` to `end_combat`, effectively skipping the interactive combat steps.
+
+## Outcome
+Declaring 0 attackers (or passing with no attacks) now correctly transitions the game immediately to the "End of Combat" step (and then likely Main Phase 2), smoothing out the gameplay flow.

+- **Backend (`GameManager.ts`)**: Implemented the `UPDATE_LIFE` action handler to ensure the life total buttons in the Game View are functional.
+
+**Result:**
+The development workflow is now more robust. Actions performed after a server code change/restart will now succeed seamlessly without requiring a manual page refresh.

+**Description:**
+Restructure the battlefield view in `GameView.tsx` from a free-form absolute positioning system to a structured, 3-zone layout (Creatures, Non-Creatures, Lands) using Flex/Grid. This improves readability and organization of the board state.
+
+**Technical Plan:**
+1.  **Categorization:** In `GameView.tsx`, split the `myBattlefield` array into three logical groups:
+    -   **Creatures:** Any card with 'Creature' type (including Artifact Creatures and Land Creatures).
+    -   **Lands:** Any card with 'Land' type that is NOT a creature.
+    -   **Others:** Artifacts, Enchantments, Planeswalkers, Battles that are neither Creatures nor Lands.
+2.  **Layout:** Replace the absolute `div` rendering with a Flexbox column container (`h-full flex flex-col`).
+    -   **Combat Zone (Top):** `flex-1` (takes remaining space). Used for Creatures. Layout: `flex-wrap`, centered.
+    -   **Support Zone (Middle):** Fixed height or proportional. Used for Artifacts/Enchantments.
+    -   **Mana Zone (Bottom):** Fixed height. Used for Lands.
+3.  **Action Logic:** Ensure drag-and-drop targeting and attacking/blocking selection still functions correctly within the new layout structure.
+4.  **Visuals:** Maintain the existing `perspective` and 3D transforms for card interaction (hover, attack state).

+title: Battlefield Cutout Style & Tapped Stack
+status: Completed

+
+## Objectives
+- Use "Cutout" (Art Crop) style for cards on the battlefield to save space.
+- Implement a stacked view for Tapped Lands on the left of the lands area.
+- Rotate tapped cards by 45 degrees instead of 90 degrees.
+
+## Implementation Details
+1.  **CardComponent**:
+    - Added `viewMode` prop ('normal' | 'cutout').
+    - If `viewMode='cutout'`, uses `card.definition.image_uris.art_crop` as src.
+    - Changed rotation class from `rotate-90` to `rotate-45`.
+
+2.  **GameView**:
+    - Updated battlefield rendering to pass `viewMode="cutout"` to all battlefield cards (Creatures, Artifacts/Enchantments, Lands).
+    - Updated card sizing on battlefield to `w-28 h-auto aspect-[4/3]` (approx 112x84px).
+    - Split Lands zone into `tappedLands` and `untappedLands`.
+    - Implemented a "stack" layout for `tappedLands` on the left side of the lands container, using absolute positioning within a relative container to create a pile effect.
+
+## Outcome
+Battlefield now uses significantly less vertical space per card row. Tapped lands are grouped neatly, reducing horizontal sprawl. Tapped cards are clearly distinct but take up less bounding box width due to 45 degree rotation compared to 90 degree (depending on aspect ratio, but arguably cleaner visual for "tapped").

+## Objectives
+- Ensure cards on the battlefield are perfectly square (1:1 aspect ratio).
+- Ensure cards display ONLY the Art Crop (cutout), not the full card text/frame.
+
+## Issue Identified
+- The visual issue (rectangular cards with text) was caused because the client code was falling back to `card.imageUrl` (full card) because `card.definition.image_uris.art_crop` was missing.
+- The `definition` property (containing raw Scryfall data) was not being propagated from the pool/deck to the `CardInstance` during game initialization on the server.
+
+## Fix Implemented
+1.  **Server Type Update**: Updated `CardObject` interface in `types.ts` to include optional `definition: any`.
+2.  **Game Manager Update**: Logic in `GameManager.ts` (specifically `addCardToGame`) updated to explicitly copy `definition` from the source data to the new card instance.
+3.  **Client UI Update**: Updated `GameView.tsx` to force square aspect ratio (`w-24 h-24`) `aspect-square` (implicitly via explicit dimensions or tailwind) and `object-cover` to handle cropping if fallback occurs, though the goal is to use the actual Art Crop source.
+
+## Verification
+- Cards added *after* this fix (e.g. by restarting game) will carry the `definition`.
+- `CardComponent.tsx` logic will now successfully find `card.definition.image_uris.art_crop` and use it.
+- `GameView.tsx` CSS `aspect-[4/3]` was changed to square-like dimensions `w-24 h-24` (via tool steps or finalization). NOTE: Previous steps might have attempted `aspect-[4/3]` again, I must ensure it is SQUARE in the final state.
+
+*Self-Correction*: The last executed step on `GameView.tsx` set it to `w-28 h-auto aspect-[4/3]`. I need to correct this to be SQUARE `w-24 h-24` or similar. I will apply a final styling fix to `GameView.tsx` to match the user's "Squared" request explicitly.

+- This happened because `RulesEngine.startGame()` (which handles the initial draw loop) was never called after the reset.
+
+## Fix Implemented
+- Updated `GameManager.ts` to instantiate a new `RulesEngine` and call `.startGame()` at the end of `restartGame`.
+- This ensures that after resetting variables, the engine immediately shuffles libraries and deals 7 cards to each player, effectively restarting the match.
+
+## Verification
+- Clicking "Restart Game" now properly resets life totals, clears the board, and deals a fresh opening hand to all players.

+title: Cache Art Crops
+status: Completed
+---
+
+## Objectives
+- Ensure "Art Crop" images are cached locally alongside "Normal" images to support offline mode and reduce external API calls.
+- Update `CardService` (Server) to download and save `.crop.jpg` files.
+- Update `PackGeneratorService` (Client) to use local `.crop.jpg` URLs when `useLocalImages` is enabled.
+
+## Implementation Details
+1.  **Server (`CardService.ts`)**:
+    - Modified `cacheImages` loop to detect if `image_uris.art_crop` (or face equivalent) exists.
+    - Implemented concurrent downloading of both the normal image and the art crop.
+    - Saves art crops with the pattern: `public/cards/images/[setCode]/[uuid].crop.jpg`.
+
+2.  **Client (`PackGeneratorService.ts`)**:
+    - Updated `processCards` to check the `useLocalImages` flag.
+    - If true, constructs the `imageArtCrop` URL using the local server path: `${origin}/cards/images/${set}/${id}.crop.jpg`.
+
+## Impact
+- When users import a cube or set collection, both image versions will now be stored.
+- The Battlefield view (which uses `art_crop`) will now load instantly from the local server cache instead of Scryfall.

+title: Organized Caching Subdirectories
+status: Completed
+---
+
+## Objectives
+- Organize cached images within edition folders into distinct subdirectories: `art_full` (normal) and `art_crop` (crop).
+- Update Server (`CardService`) to save images to these new paths.
+- Update Client (`PackGeneratorService`) to construct paths referencing these new subdirectories.
+
+## Implementation Details
+1.  **Server (`CardService.ts`)**:
+    - Changed normal image save path to: `[imagesDir]/[setCode]/art_full/[uuid].jpg`
+    - Changed art crop save path to: `[imagesDir]/[setCode]/art_crop/[uuid].jpg`
+    - Note: Extension is standardized to `.jpg` for simplicity.
+
+2.  **Client (`PackGeneratorService.ts`)**:
+    - Updated `image` property to use `.../[setCode]/art_full/[id].jpg`
+    - Updated `imageArtCrop` property to use `.../[setCode]/art_crop/[id].jpg`
+
+## Migration Note
+- Existing cached images in the root of `[setCode]` folder will be ignored by the new logic.
+- Users will need to re-parse or re-import sets/cubes to populate the new folder structure. This is an intentional breaking change for cleaner organization.
+
+## Outcome
+Filesystem is now cleaner with clear separation between full card art and crop art.

+title: Fix Cube Session Clear
+status: Completed
+---
+
+## Objectives
+- Fix the "Clear Session" functionality in `CubeManager` which was failing to fully reset the application state.
+
+## Diagnosis
+- The previous implementation relied on setting state via props (`setPacks([])`), but depending on the timing of React's state updates and `App.tsx`'s persistence logic, the cleared state might not have been persisted to `localStorage` before a reload.
+- The `handleReset` function did not explicitly clear the `generatedPacks` and `availableLands` keys from `localStorage`, assuming the parent component would handle it via `useEffect`.
+
+## Fix Implemented
+- Refactored `handleReset` in `CubeManager.tsx`.
+- Added explicit `localStorage.removeItem('generatedPacks')` and `localStorage.removeItem('availableLands')` calls.
+- Added explicit calls to reset all local component state (`inputText`, `processedData`, etc.) and their respective storage keys.
+- Wrapped the logic in a `try/catch` block with toast notifications for feedback.
+- This ensures a robust, hard reset of the drafting session.
+
+## Verification
+- User can now click "Clear Session", confirm the dialog, and immediately see a cleared interface and toast success message.
+- Reloading the page will confirm the session is truly empty.
