Update test demos for new Python API and entity system

- Update all text input demos to use new Entity constructor signature
- Fix pathfinding showcase to work with new entity position handling
- Remove entity_waypoints tracking in favor of simplified movement
- Delete obsolete exhaustive_api_demo.py (superseded by newer demos)
- Adjust entity creation calls to match Entity((x, y), texture, sprite_index) pattern

All demos now properly demonstrate the updated API while maintaining their
original functionality for showcasing engine features.

 A Python-powered 2D game engine for creating roguelike games, built with C++ and SFML.
 
+* Core roguelike logic from libtcod: field of view, pathfinding
+* Animate sprites with multiple frames. Smooth transitions for positions, sizes, zoom, and camera
+* Simple GUI element system allows keyboard and mouse input, composition
+* No compilation or installation necessary. The runtime is a full Python environment; "Zip And Ship"
+
+![ Image ]()
+
 **Pre-Alpha Release Demo**: my 7DRL 2025 entry *"Crypt of Sokoban"* - a prototype with buttons, boulders, enemies, and items.
 
-## Tenets
-
-- **Python & C++ Hand-in-Hand**: Create your game without ever recompiling. Your Python commands create C++ objects, and animations can occur without calling Python at all.
-- **Simple Yet Flexible UI System**: Sprites, Grids, Frames, and Captions with full animation support
-- **Entity-Component Architecture**: Implement your game objects with Python integration
-- **Built-in Roguelike Support**: Dungeon generation, pathfinding, and field-of-view via libtcod (demos still under construction)
-- **Automation API**: PyAutoGUI-inspired event generation framework. All McRogueFace interactions can be performed headlessly via script: for software testing or AI integration
-- **Interactive Development**: Python REPL integration for live game debugging. Use `mcrogueface` like a Python interpreter

 ## Quick Start
 
+**Download**: 
+
+- The entire McRogueFace visual framework:
+  - **Sprite**: an image file or one sprite from a shared sprite sheet
+  - **Caption**: load a font, display text
+  - **Frame**: A rectangle; put other things on it to move or manage GUIs as modules
+  - **Grid**: A 2D array of tiles with zoom + position control
+  - **Entity**: Lives on a Grid, displays a sprite, and can have a perspective or move along a path
+  - **Animation**: Change any property on any of the above over time

+If you are building McRogueFace to implement game logic or scene configuration in C++, you'll have to compile the project.
+
+If you are writing a game in Python using McRogueFace, you only need to rename and zip/distribute the `build` directory.
+
+## Philosophy
+
+- **C++ every frame, Python every tick**: All rendering data is handled in C++. Structure your UI and program animations in Python, and they are rendered without Python. All game logic can be written in Python.
+- **No Compiling Required; Zip And Ship**: Implement your game objects with Python, zip up McRogueFace with your "game.py" to ship
+- **Built-in Roguelike Support**: Dungeon generation, pathfinding, and field-of-view via libtcod 
+- **Hands-Off Testing**: PyAutoGUI-inspired event generation framework. All McRogueFace interactions can be performed headlessly via script: for software testing or AI integration
+- **Interactive Development**: Python REPL integration for live game debugging. Use `mcrogueface` like a Python interpreter

+# McRogueFace - Development Roadmap
+
+## 🚨 URGENT PRIORITIES - July 12, 2025 🚨
+
+### CRITICAL: RoguelikeDev Tutorial Event starts July 15! (3 days)
+
+#### 1. Tutorial Status & Blockers
+- [x] **Part 0**: Complete (Starting McRogueFace) 
+- [x] **Part 1**: Complete (Setting up grid and tile sheet)
+- [ ] **Part 2**: Draft exists but BLOCKED by animation issues - PRIORITY FIX!
+- [ ] **Parts 3-6**: Machine-generated drafts need complete rework
+- [ ] **Parts 7-15**: Need creation this weekend
+
+**Key Blockers**:
+- Need smooth character movement animation (Pokemon-style)
+- Grid needs walkable grass center, non-walkable tree edges
+- Input queueing during animations not working properly
+
+#### 2. Animation System Critical Issues 🚨
+**BLOCKER FOR TUTORIAL PART 2**:
+- [ ] **Input Queue System**: Holding arrow keys doesn't queue movements
+  - Animation must complete before next input accepted
+  - Need "press and hold" that queues ONE additional move
+  - Goal: Pokemon-style smooth continuous movement
+- [ ] **Collision Reservation**: When entity starts moving, should block destination
+  - Prevents overlapping movements
+  - Already claimed tiles should reject incoming entities
+- [x] **Segfault Fix**: Refactored from bare pointers to weak references ✅
+
+#### 3. Grid Clicking BROKEN in Headless Mode 🚨
+**MAJOR DISCOVERY**: All click events commented out!
+- [ ] **#111** - Grid Click Events Broken in Headless: All click events commented out
+- [ ] **Grid Click Coordinates**: Need tile coords, not just mouse coords
+- [ ] **Nested Grid Support**: Clicks must work on grids within frames
+- [ ] **No Error Reporting**: System claimed complete but isn't
+
+#### 4. Python API Consistency Crisis
+**Tutorial Writing Reveals Major Issues**:
+- [ ] **#101/#110** - Inconsistent Constructors: Each class has different requirements
+- [ ] **#109** - Vector Class Broken: No [0], [1] indexing like tuples
+- [ ] **#112** - Object Splitting Bug: Python derived classes lose type in collections
+  - Shared pointer extracted, Python reference discarded
+  - Retrieved objects are base class only
+  - No way to cast back to derived type
+- [ ] **Need Systematic Generation**: All bindings should be consistent
+- [x] **UIGrid TCOD Integration** (8 hours) ✅ COMPLETED!
+  - ✅ Add TCODMap* to UIGrid constructor with proper lifecycle
+  - ✅ Implement complete Dijkstra pathfinding system
+  - ✅ Create mcrfpy.libtcod submodule with Python bindings
+  - ✅ Fix critical PyArg bug preventing Color object assignments

+  - [ ] **#114** - Create CellView for ergonomic .at((x,y)) access (deferred)
+- [x] **UIEntity Pathfinding** (4 hours) ✅ COMPLETED!
+  - ✅ Implement Dijkstra maps for multiple targets in UIGrid
+  - ✅ Add path_to(target) method using A* to UIEntity
+  - ✅ Cache paths in UIEntity for performance
+
+#### 3. Performance Critical Path
+- [ ] **#115** - Implement SpatialHash for 10,000+ entities (2 hours)
+- [ ] **#116** - Add dirty flag system to UIGrid (1 hour)
+- [ ] **#113** - Batch update context managers (2 hours)
+- [ ] **#117** - Memory pool for entities (2 hours)
+
+#### 4. Bug Fixing Pipeline
+- [ ] **#125** - Set up GitHub Issues automation
+- [ ] Create test for each bug before fixing
+- [ ] Track: Memory leaks, Segfaults, Python/C++ boundary errors
+
+---
+
+## 🏗️ PROPOSED ARCHITECTURE IMPROVEMENTS (From July 12 Analysis)
+
+### Object-Oriented Design Overhaul
+1. **Scene System Revolution**:
+   - [ ] **#118** - Make Scene derive from Drawable (scenes are drawn!)
+   - [ ] Give scenes position and visibility properties
+   - [ ] Scene selection by visibility (auto-hide old scene)
+   - [ ] Replace transition system with animations
+
+2. **Animation System Enhancements**:
+   - [ ] **#119** - Add proper completion callbacks (object + animation params)
+   - [ ] **#120** - Prevent property conflicts (exclusive locking)
+   - [ ] Currently using timer sync workarounds
+
+3. **Timer System Improvements**:
+   - [ ] **#121** - Replace string-dictionary system with objects
+   - [ ] Add start(), stop(), pause() methods
+   - [ ] Implement proper one-shot mode
+   - [ ] Pass timer object to callbacks (not just ms)
+
+4. **Parent-Child UI Relationships**:
+   - [ ] **#122** - Add parent field to UI drawables (like entities have)
+   - [ ] Implement append/remove/extend with auto-parent updates
+   - [ ] Auto-remove from old parent when adding to new
+
+### Performance Optimizations Needed
+- [ ] **Grid Rendering**: Consider texture caching vs real-time
+- [ ] **#123** - Subgrid System: Split large grids into 256x256 chunks
+- [ ] **#116** - Dirty Flagging: Propagate from base class up
+- [ ] **#124** - Animation Features: Tile color animation, sprite cycling
+
+---
+
+## ⚠️ CLAUDE CODE QUALITY CONCERNS (6-7 Weeks In)
+
+### Issues Observed:
+1. **Declining Quality**: High quantity but low quality results
+2. **Not Following Requirements**: Ignoring specific implementation needs
+3. **Bad Practices**:
+   - Creating parallel copies (animation_RAII.cpp, _fixed, _final versions)
+   - Should use Git, not file copies
+   - Claims functionality "done" when stubbed out
+4. **File Management Problems**:
+   - Git operations reset timestamps
+   - Can't determine creation order of multiple versions
+
+### Recommendations:
+- Use Git for version control exclusively
+- Fix things in place, not copies
+- Acknowledge incomplete functionality
+- Follow project's implementation style
+
+---
+
+## 🎯 STRATEGIC ARCHITECTURE VISION
+
+### Three-Layer Grid Architecture (From Compass Research)
+Following successful roguelike patterns (Caves of Qud, Cogmind, DCSS):
+
+1. **Visual Layer** (UIGridPoint) - Sprites, colors, animations
+2. **World State Layer** (TCODMap) - Walkability, transparency, physics
+3. **Entity Perspective Layer** (UIGridPointState) - Per-entity FOV, knowledge
+
+### Performance Architecture (Critical for 1000x1000 maps)
+- **Spatial Hashing** for entity queries (not quadtrees!)
+- **Batch Operations** with context managers (10-100x speedup)
+- **Memory Pooling** for entities and components
+- **Dirty Flag System** to avoid unnecessary updates
+- **Zero-Copy NumPy Integration** via buffer protocol
+
+### Key Insight from Research
+"Minimizing Python/C++ boundary crossings matters more than individual function complexity"
+- Batch everything possible
+- Use context managers for logical operations
+- Expose arrays, not individual cells
+- Profile and optimize hot paths only
+
+---
+
+## Project Status: 🎉 ALPHA 0.1 RELEASE! 🎉
+
+**Current State**: Documentation system complete, TCOD integration urgent  
+**Latest Update**: Tutorial Parts 0-6 complete with documentation (2025-07-11)  
+**Branch**: alpha_streamline_2  
+**Open Issues**: ~46 remaining + URGENT TCOD/Tutorial work
+
+---
+
+## 📋 TCOD Integration Implementation Details
+
+### Phase 1: Core UIGrid Integration (Day 1 Morning)
+```cpp
+// UIGrid.h additions
+class UIGrid : public UIDrawable {
+private:
+    TCODMap* world_state;  // Add TCOD map
+    std::unordered_map<int, UIGridPointState*> entity_perspectives;
+    bool batch_mode = false;
+    std::vector<CellUpdate> pending_updates;
+```
+
+### Phase 2: Python Bindings (Day 1 Afternoon)
+```python
+# New API surface
+grid = mcrfpy.Grid(100, 100)
+grid.compute_fov(player.x, player.y, radius=10)  # Returns visible cells
+grid.at((x, y)).walkable = False  # Ergonomic access
+with grid.batch_update():  # Context manager for performance
+    # All updates batched
+```
+
+### Phase 3: Entity Integration (Day 2 Morning)
+```python
+# UIEntity additions
+entity.path_to(target_x, target_y)  # A* pathfinding
+entity.flee_from(threat)  # Dijkstra map
+entity.can_see(other_entity)  # FOV check
+```
+
+### Critical Success Factors:
+1. **Batch everything** - Never update single cells in loops
+2. **Lazy evaluation** - Only compute FOV for entities that need it
+3. **Sparse storage** - Don't store full grids per entity
+4. **Profile early** - Find the 20% of code taking 80% of time

+
+## 🚀 Alpha Streamline 2 - Comprehensive Phase Plan
+
+### Phase 1: Foundation Stabilization (1-2 weeks)
+**Goal**: Safe, predictable base for all future work
+```
+1. #7 - Audit and fix unsafe constructors (CRITICAL - do first!)
+   - Find all manually implemented no-arg constructors
+   - Verify map compatibility requirements
+   - Make pointer-safe or remove
+   
+2. #71 - _Drawable base class implementation
+   - Common properties: x, y, w, h, visible, opacity
+   - Virtual methods: get_bounds(), render()
+   - Proper Python inheritance setup
+   
+3. #87 - visible property
+   - Add to base class
+   - Update all render methods to check
+   
+4. #88 - opacity property (depends on #87)
+   - 0.0-1.0 float range
+   - Apply in render methods
+   
+5. #89 - get_bounds() method
+   - Virtual method returning (x, y, w, h)
+   - Override in each UI class
+   
+6. #98 - move()/resize() convenience methods
+   - move(dx, dy) - relative movement
+   - resize(w, h) - absolute sizing
+```
+*Rationale*: Can't build on unsafe foundations. Base class enables all UI improvements.
+
+### Phase 2: Constructor & API Polish (1 week)
+**Goal**: Pythonic, intuitive API
+```
+1. #101 - Standardize (0,0) defaults for all positions
+2. #38 - Frame children parameter: Frame(children=[...])
+3. #42 - Click handler in __init__: Button(click=callback)
+4. #90 - Grid size tuple: Grid(grid_size=(10, 10))
+5. #19 - Sprite texture swapping: sprite.texture = new_texture
+6. #52 - Grid skip out-of-bounds entities (performance)
+```
+*Rationale*: Quick wins that make the API more pleasant before bigger changes.
+
+### Phase 3: Entity Lifecycle Management (1 week)
+**Goal**: Bulletproof entity/grid relationships
+```
+1. #30 - Entity.die() and grid association
+   - Grid.entities.append(e) sets e.grid = self
+   - Grid.entities.remove(e) sets e.grid = None
+   - Entity.die() calls self.grid.remove(self)
+   - Entity can only be in 0 or 1 grid
+   
+2. #93 - Vector arithmetic methods
+   - add, subtract, multiply, divide
+   - distance, normalize, dot product
+   
+3. #94 - Color helper methods
+   - from_hex("#FF0000"), to_hex()
+   - lerp(other_color, t) for interpolation
+   
+4. #103 - Timer objects
+   timer = mcrfpy.Timer("my_timer", callback, 1000)
+   timer.pause()
+   timer.resume()
+   timer.cancel()
+```
+*Rationale*: Games need reliable entity management. Timer objects enable entity AI.
+
+### Phase 4: Visibility & Performance (1-2 weeks)
+**Goal**: Only render/process what's needed
+```
+1. #10 - [UNSCHEDULED] Full visibility system with AABB
+   - Postponed: UIDrawables can exist in multiple collections
+   - Cannot reliably determine screen position due to multiple render contexts
+   - Needs architectural solution for parent-child relationships
+   
+2. #52 - Grid culling (COMPLETED in Phase 2)
+   
+3. #39/40/41 - Name system for finding elements
+   - name="button1" property on all UIDrawables
+   - only_one=True for unique names
+   - scene.find("button1") returns element
+   - collection.find("enemy*") returns list
+   
+4. #104 - Basic profiling/metrics
+   - Frame time tracking
+   - Draw call counting
+   - Python vs C++ time split
+```
+*Rationale*: Performance is feature. Finding elements by name is huge QoL.
+
+### Phase 5: Window/Scene Architecture ✅ COMPLETE! (2025-07-06)
+**Goal**: Modern, flexible architecture
+```
+1. ✅ #34 - Window object (singleton first)
+   window = mcrfpy.Window.get()
+   window.resolution = (1920, 1080)
+   window.fullscreen = True
+   window.vsync = True
+   
+2. ✅ #1 - Window resize events
+   scene.on_resize(self, width, height) callback implemented
+   
+3. ✅ #61 - Scene object (OOP scenes)
+   class MenuScene(mcrfpy.Scene):
+       def on_keypress(self, key, state):
+           # handle input
+       def on_enter(self):
+           # setup UI
+       def on_exit(self):
+           # cleanup
+       def update(self, dt):
+           # frame update
+           
+4. ✅ #14 - SFML exposure research
+   - Completed comprehensive analysis
+   - Recommendation: Direct integration as mcrfpy.sfml
+   - SFML 3.0 migration deferred to late 2025
+   
+5. ✅ #105 - Scene transitions
+   mcrfpy.setScene("menu", "fade", 1.0)
+   # Supports: fade, slide_left, slide_right, slide_up, slide_down
+```
+*Result*: Entire window/scene system modernized with OOP design!
+
+### Phase 6: Rendering Revolution (3-4 weeks) ✅ COMPLETE!
+**Goal**: Professional rendering capabilities
+```
+1. ✅ #50 - Grid background colors [COMPLETED]
+   grid.background_color = mcrfpy.Color(50, 50, 50)
+   - Added background_color property with animation support

+
+## 📋 Phase 6 Implementation Strategy
+
+### RenderTexture Overhaul (#6) - Technical Approach
+
+**Current State**:
+- UIGrid already uses RenderTexture for entity rendering
+- Scene transitions use RenderTextures for smooth animations
+- Direct rendering to window for Frame, Caption, Sprite
+
+**Implementation Plan**:
+1. **Base Infrastructure**:
+   - Add `sf::RenderTexture* target` to UIDrawable base
+   - Modify `render()` to check if target exists
+   - If target: render to texture, then draw texture to parent
+   - If no target: render directly (backward compatible)
+
+2. **Clipping Support**:
+   - Frame enforces bounds on children via RenderTexture
+   - Children outside bounds are automatically clipped
+   - Nested frames create render texture hierarchy
+
+3. **Performance Optimization**:
+   - Lazy RenderTexture creation (only when needed)
+   - Dirty flag system (only re-render when changed)
+   - Texture pooling for commonly used sizes
+
+4. **Integration Points**:
+   - Scene transitions already working with RenderTextures
+   - UIGrid can be reference implementation
+   - Test with deeply nested UI structures
+
+**Quick Wins Before Core Work**:
+1. **Grid Background (#50)** - 30 min implementation
+   - Add `background_color` and `background_texture` properties
+   - Render before entities in UIGrid::render()
+   - Good warm-up before tackling RenderTexture
+
+2. **Research Tasks**:
+   - Study UIGrid's current RenderTexture usage
+   - Profile scene transition performance
+   - Identify potential texture size limits

+
+## 🔮 FUTURE VISION: Pure Python Extension Architecture
+
+### Concept: McRogueFace as a Traditional Python Package
+**Status**: Unscheduled - Long-term vision
+**Complexity**: Major architectural overhaul
+
+Instead of being a C++ application that embeds Python, McRogueFace could be redesigned as a pure Python extension module that can be installed via `pip install mcrogueface`.
+
+### Technical Approach
+1. **Separate Core Engine from Python Embedding**
+   - Extract SFML rendering, audio, and input into C++ extension modules
+   - Remove embedded CPython interpreter
+   - Use Python's C API to expose functionality
+
+2. **Module Structure**
+   ```
+   mcrfpy/
+   ├── __init__.py          # Pure Python coordinator
+   ├── _core.so             # C++ rendering/game loop extension
+   ├── _sfml.so             # SFML bindings
+   ├── _audio.so            # Audio system bindings
+   └── engine.py            # Python game engine logic
+   ```
+
+3. **Inverted Control Flow**
+   - Python drives the main loop instead of C++
+   - C++ extensions handle performance-critical operations
+   - Python manages game logic, scenes, and entity systems
+
+### Benefits
+- **Standard Python Packaging**: `pip install mcrogueface`
+- **Virtual Environment Support**: Works with venv, conda, poetry
+- **Better IDE Integration**: Standard Python development workflow  
+- **Easier Testing**: Use pytest, standard Python testing tools
+- **Cross-Python Compatibility**: Support multiple Python versions
+- **Modular Architecture**: Users can import only what they need
+
+### Challenges
+- **Major Refactoring**: Complete restructure of codebase
+- **Performance Considerations**: Python-driven main loop overhead
+- **Build Complexity**: Multiple extension modules to compile
+- **Platform Support**: Need wheels for many platform/Python combinations
+- **API Stability**: Would need careful design to maintain compatibility
+
+### Implementation Phases (If Pursued)
+1. **Proof of Concept**: Simple SFML binding as Python extension
+2. **Core Extraction**: Separate rendering from Python embedding
+3. **Module Design**: Define clean API boundaries
+4. **Incremental Migration**: Move systems one at a time
+5. **Compatibility Layer**: Support existing games during transition
+
+### Example Usage (Future Vision)
+```python
+import mcrfpy
+from mcrfpy import Scene, Frame, Sprite, Grid
+
+# Create game directly in Python
+game = mcrfpy.Game(width=1024, height=768)
+
+# Define scenes using Python classes
+class MainMenu(Scene):
+    def on_enter(self):
+        self.ui.append(Frame(100, 100, 200, 50))
+        self.ui.append(Sprite("logo.png", x=400, y=100))
+    
+    def on_keypress(self, key, pressed):
+        if key == "ENTER" and pressed:
+            self.game.set_scene("game")
+
+# Run the game
+game.add_scene("menu", MainMenu())
+game.run()
+```
+
+This architecture would make McRogueFace a first-class Python citizen, following standard Python packaging conventions while maintaining high performance through C++ extensions.

+
+## 🚀 IMMEDIATE NEXT STEPS (Priority Order)
+
+### TODAY (July 12) - CRITICAL PATH:
+1. **FIX ANIMATION BLOCKERS** for Tutorial Part 2:
+   - Implement input queueing during animations
+   - Add destination square reservation
+   - Test Pokemon-style continuous movement
+2. **FIX GRID CLICKING** (discovered broken in headless):
+   - Uncomment and implement click events
+   - Add tile coordinate conversion
+   - Enable nested grid support
+3. **CREATE TUTORIAL ANNOUNCEMENT** if blockers fixed
+
+### Weekend (July 13-14) - Tutorial Sprint:
+1. **Regenerate Parts 3-6** (machine drafts are broken)
+2. **Create Parts 7-10**: Interface, Items, Targeting, Save/Load
+3. **Create Parts 11-15**: Dungeon levels, difficulty, equipment
+4. **Post more frequently during event** (narrator emphasis)
+
+### Architecture Decision Log:
+- **DECIDED**: Use three-layer architecture (visual/world/perspective)
+- **DECIDED**: Spatial hashing over quadtrees for entities
+- **DECIDED**: Batch operations are mandatory, not optional
+- **DECIDED**: TCOD integration as mcrfpy.libtcod submodule
+- **DECIDED**: Tutorial must showcase McRogueFace strengths, not mimic TCOD
+
+### Risk Mitigation:
+- **If TCOD integration delays**: Use pure Python FOV for tutorial
+- **If performance issues**: Focus on <100x100 maps for demos
+- **If tutorial incomplete**: Ship with 4 solid parts + roadmap
+- **If bugs block progress**: Document as "known issues" and continue
+
