+# High Velocity UX & Strict Engine (Part 2)
 
-# 2024-12-18 18:25:00 - High-Velocity UX Implementation (Part 2: Gestures & Backend Polish)
+## Status: Completed
 
-## Description
-Advanced the High-Velocity UX implementation by introducing the Gesture Engine and refining the backend Rules Engine to support card movement during resolution.
+## Objectives
+- Implement "Manual Mana Engine" allowing players to add mana to their pool via interaction.
+- Implement "Strict Combat Engine" supporting `DECLARE_ATTACKERS` and `DECLARE_BLOCKERS` phases and validation.
+- Implement "High Velocity UX" with Swipe-to-Tap and Swipe-to-Attack gestures.
+- Enhance `GameView` with Mana Pool display and visual feedback for combat declarations.
+- Contextualize `SmartButton` to handle complex actions like declaring specific attackers.
 
-## Key Changes
-1.  **Gesture Manager**: Implemented `GestureManager.tsx` and integrated it into the Battlefield.
-    - Provides Swipe-to-Tap functionality via pointer tracking and intersection checking.
-    - Draws a visual SVG path trail for user feedback.
-    - Integrated with `CardComponent` via `useGesture` hook to register card DOM elements.
-2.  **Stack Visualizer**: Implemented `StackVisualizer.tsx` to render the stack on the right side of the screen, showing strict object ordering.
-3.  **Backend Rules Engine**:
-    - Updated `RulesEngine.ts` to fully implement `resolveTopStack` and `drawCard`.
-    - Added `moveCardToZone` helper to manage state transitions (untapping, resetting position).
-    - Fixed typings and logic flow for resolving spells to graveyard vs battlefield.
+## Implementation Details
+
+### Backend (Rules Engine)
+- **Mana System**: Added `addMana` method to `RulesEngine` and `manaPool` to `PlayerState`. Implemented `emptyManaPools` logic on step transition.
+- **Combat Logic**: Implemented `declareAttackers` (checking summoning sickness, tapping, setting attacking target) and `declareBlockers` logic.
+- **Action Handling**: Updated `GameManager` to handle `ADD_MANA` and auto-generate mana when tapping Basic Lands via `TAP_CARD` action (legacy compatibility wrapper).
+
+### Frontend (GameView)
+- **Mana Pool UI**: Added a compact Mana Pool display in the player life area, showing WUBRGC counts.
+- **Gesture Manager Upgrade**: Enhanced `GestureManager` to detect swipe direction:
+  - **Slash (Horizontal)**: Tap Card.
+  - **Thrust (Vertical Up)**: Attack (if in combat step).
+  - **Thrust (Vertical Down)**: Cancel Attack.
+- **Combat Visuals**: Implemented `proposedAttackers` local state. Cards proposed to attack are visually lifted (`translateY(-40px)`) and glow red (`box-shadow`, `ring`).
+- **Smart Button**: Updated to accept `contextData`. In `declare_attackers` step, it displays "Attack with N" and sends the list of proposed attackers.
+
+### Type Synchronization
+- Synced `CardInstance` (Client) with `CardObject` (Server) to include `attacking` and `blocking` fields.
 
 ## Next Steps
-- Implement Radial Menu context for activating abilities.
-- Add sound effects for gestures.
-- Polish visual transitions for stack resolution.
+- Verify Multiplayer Sync (Socket events are already in place).
+- Implement "Blocking" UI (similar to Attacking but for defenders).
+- Implement "Order Blockers" / "Damage Assignment" if strict compliance is enforced (currently simplified to auto-damage).

+# Strict Rules & Blocking UI (Part 3)
+
+## Status: Completed
+
+## Objectives
+- Integrate Strict Actions (`PLAY_LAND`, `CAST_SPELL`) with precise positioning.
+- Implement Blocking UI including visual feedback (Attacking/Blocking badges, Rings).
+- Implement Drag-and-Drop Targeting Logic (Spell -> Target, Blocker -> Attacker).
+- Implement Visual "Targeting Tether" overlay.
+
+## Implementation Details
+
+### Backend (Rules Engine)
+- **Positioning**: Updated `playLand` and `castSpell` to accept `{x, y}` coordinates.
+- **Stack Resolution**: Updated `resolveTopStack` to respect the stored resolution position when moving cards to the battlefield.
+- **Action Handling**: Updated `GameManager` to pass `position` payload to the engine.
+
+### Frontend (GameView)
+- **Drop Logic**:
+  - `handleZoneDrop`: Detects drop on "Battlefield". Differentiates Land (Play) vs Spell (Cast). Calculates relative % coordinates.
+  - `handleCardDrop`: Detects drop on a Card.
+    - If `declare_blockers` step: Assigns blocker (drag My Creature -> Opponent Creature).
+    - Else: Casts Spell with Target.
+  - `handlePlayerDrop`: Detects drop on Opponent Avatar -> Cast Spell with Target Player.
+- **Blocking Visualization**:
+  - **Opponent Cards**: Show "ATTACKING" badge (Red Ring + Shadow) if `attacking === property`.
+  - **My Cards**: Show "Blocking" badge (Blue Ring) if in local `proposedBlockers` map.
+- **Targeting Tether**:
+  - Implemented `tether` state (`startX`, `currentX`, etc.).
+  - Added `onDrag` handler to `CardComponent` to track HTML5 DnD movement.
+  - Rendered Full-screen SVG overlay with Bezier curve (`Q` command) and arrow marker.
+  - Dynamic styling: Cyan (Spells) vs Blue (Blocking).
+
+## Next Steps
+- **Layer System**: Implement 7-layer P/T calculation for accurate power/toughness display.
+- **Mulligan System**: Implement Strict Mulligan rules.
+- **Token Creation**: Support creating tokens.

+# Strict Engine Enhancements: Layers, Tokens, Mulligan
+
+## Status: Completed
+
+## Objectives
+- Implement Basic Layer System for continuous effects (P/T modifications).
+- Implement Token Creation mechanism.
+- Implement Mulligan System (London Rule).
+- Update Game Lifecycle to include Setup/Mulligan phase.
+
+## Logic Overview
+
+### Layer System (`RulesEngine.recalculateLayers`)
+- Implements Layer 7 (Power/Toughness) basics:
+    - **Layer 7b**: Set P/T (`set_pt`).
+    - **Layer 7c**: Modify P/T (`pt_boost`).
+    - **Layer 7d**: Counters (`+1/+1`, `-1/-1`).
+- `recalculateLayers` is called automatically whenever priority resets or actions occur.
+- Modifiers with `untilEndOfTurn: true` are automatically cleared in the `cleanup` step.
+
+### Token Creation
+- New action `CREATE_TOKEN` added.
+- `createToken` method constructs a CardObject on the battlefield with defined stats.
+- Triggers layer recalculation immediately.
+
+### Mulligan System
+- **New Phase**: `setup`, **New Step**: `mulligan`.
+- Game starts in `setup/mulligan`.
+- **Logic**:
+    - If a player has 0 cards and hasn't kept, they draw 7 automatically.
+    - Action `MULLIGAN_DECISION`:
+        - `keep: false` -> Shuffles hand into library, draws 7, increments `mulliganCount`.
+        - `keep: true` -> Validates `cardsToBottom` count matches `mulliganCount`. Moves excess cards to library. Sets `handKept = true`.
+- When all players keep, the engine automatically advances to `beginning/untap`.
+- Supports London Mulligan rule (Draw 7, put X on bottom).
+
+## Technical Changes
+- Updated `StrictGameState` and `PlayerState` types.
+- Updated `GameManager` initialization and action switching.
+- Updated `RulesEngine` transition logic.
+
+## Remaining/Next
+- Frontend UI for Mulligan (Needs a Modal to Keep/Mull).
+- Frontend UI for "Cards to Bottom" selection if X > 0.
+- Frontend UI to visualize Tokens.

+# 2024-12-18 - High Velocity UX & Strict Engine Completion
+
+## Status: Completed
+
+We have successfully implemented the core strict rules engine features and the high-velocity UX components.
+
+### 1. Rules Engine Refinement
+- **State-Based Actions (SBAs)**: Implemented robust SBA loop in `RulesEngine.ts`, utilizing `processStateBasedActions()` to cyclically check conditions (Lethal Damage, Legend Rule, Aura Validity) and recalculate layers until stability.
+- **Layer System**: Implemented Layer 7 (Power/Toughness) calculations, handling Base P/T, Setting Effects, Boosts, and Counters.
+- **Mana Engine**: Backend support for manual mana pool management (emptying at end of steps).
+- **Code Cleanup**: Resolved critical linting errors and structural issues in `RulesEngine.ts` (duplicate methods, undefined checks).
+
+### 2. High-Velocity Frontend UX
+- **Inspector Overlay**: Created `InspectorOverlay.tsx` to visualize detailed card state (P/T modifications, counters, oracle text) with a modern, glassmorphism UI.
+- **Smart Button Advanced**: Implemented "Yield" toggle on the Smart Button. Users can long-press (simulated via pointer down) to yield priority until end of turn (or cancel).
+- **Radial Menu**: Created a generic `RadialMenu.tsx` component. Integrated it into the `GameView` via the Context Menu ("Add Mana...") to allow quick manual mana color selection for dual/utility lands.
+- **Context Menu Integration**: Added "Inspect Details" and "Add Mana..." options to the card context menu.
+
+### 3. Verification
+- **GameView Integration**: All new components (`InspectorOverlay`, `SmartButton`, `RadialMenu`) are fully integrated into `GameView.ts`.
+- **Type Safety**: Updated `types/game.ts` to ensure consistency between client and server (e.g., `attachedTo`, `ptModification` properties).
+
+## Next Steps
+- **Playtesting**: Validate the interaction between strict rules (timing, priority) and the new UX in a live multiplayer environment.
+- **Visual Polish**: Refine animations for Inspector and Radial Menu opening.
+- **Complex Card Logic**: Expand the engine to support more complex replacement effects and specific card scripts.
