GridView is a new UIDrawable that renders a GridData object independently.
Multiple GridViews can reference the same Grid for split-screen, minimap,
or different camera/zoom perspectives on shared grid state.
- New files: UIGridView.h/cpp with full rendering pipeline (copied from
UIGrid::render, adapted to use grid_data pointer)
- Add UIGRIDVIEW to PyObjectsEnum
- Add UIGRIDVIEW cases to all switch(derived_type()) sites:
Animation.cpp, UICollection.cpp, UIDrawable.cpp, McRFPy_API.cpp,
ImGuiSceneExplorer.cpp
- Python type: mcrfpy.GridView(grid=, pos=, size=, zoom=, fill_color=)
- Properties: grid, center, zoom, fill_color, texture
- Register type with metaclass for callback support
All 258 existing tests pass. New GridView test suite added.

Replace ~230 occurrences of PyObject_GetAttrString(McRFPy_API::mcrf_module, "TypeName")
with direct &mcrfpydef::PyXxxType references across 32 source files.
Each PyObject_GetAttrString call returns a new reference. When used inline
in PyObject_IsInstance(), that reference was immediately leaked. When used
for tp_alloc, the reference required careful Py_DECREF management that was
often missing on error paths.
Direct type references are compile-time constants that never need reference
counting, eliminating ~230 potential leak sites and removing ~100 lines of
Py_DECREF/Py_XDECREF cleanup code.
Also adds extractDrawable() helper in UICollection.cpp to replace repeated
8-way type-check-and-extract chains with a single function call.

Game code uses standard Python file I/O to mcrfpy.save_dir with no platform
branching. On WASM, builtins.open() is monkeypatched so writes to /save/
auto-sync IDBFS on close, making persistence transparent.
API: mcrfpy.save_dir (str), mcrfpy._sync_storage() (auto-called on WASM)

All 27 PyTypeObject declarations in namespace mcrfpydef headers changed
from `static` to `inline` (C++17), ensuring a single global instance
across translation units. This fixes the root cause of stale-type-pointer
segfaults where only the McRFPy_API.cpp copy was PyType_Ready'd.
Replaced ~20 PyTypeCache call sites and 2 PyRAII::PyTypeRef lookups with
direct &mcrfpydef::Type references. Deleted PyTypeCache.h/.cpp,
PyObjectUtils.h, and PyRAII.h (all were workarounds for the static bug).
228/228 tests pass.

This commit enables McRogueFace to compile without SFML dependencies
when built with -DMCRF_HEADLESS, a prerequisite for Emscripten/WebAssembly
support.
Changes:
- Add src/platform/HeadlessTypes.h (~900 lines of SFML type stubs)
- Consolidate all SFML includes through src/Common.h (15 files fixed)
- Wrap ImGui-SFML with #ifndef MCRF_HEADLESS guards
- Disable debug console/explorer in headless builds
- Add comprehensive research document: docs/EMSCRIPTEN_RESEARCH.md
The headless build compiles successfully but uses stub implementations
that return failure/no-op. This proves the abstraction boundary is clean
and enables future work on alternative backends (VRSFML, Emscripten).
What still works in headless mode:
- Python interpreter and script execution
- libtcod integrations (pathfinding, FOV, noise, BSP, heightmaps)
- Timer system and scene management
- All game logic and data structures
Build commands:
Normal: make
Headless: cmake .. -DCMAKE_CXX_FLAGS="-DMCRF_HEADLESS" && make
Addresses #158

- Remove mcrfpy.libtcod submodule entirely
- Add mcrfpy.bresenham(start, end, include_start=True, include_end=True)
- Accepts tuples or Vector objects for positions
- Returns list of (x, y) tuples along the line
- compute_fov() was redundant with Grid.compute_fov()
- line() functionality now available as top-level bresenham()

Enables background Python threads to safely modify UI objects by
synchronizing with the render loop at frame boundaries.
Implementation:
- FrameLock class provides mutex/condvar synchronization
- GIL released during window.display() allowing background threads to run
- Safe window opens between frames for synchronized UI updates
- mcrfpy.lock() context manager blocks until safe window, then executes
- Main thread detection: lock() is a no-op when called from callbacks
or script initialization (already synchronized)
Usage:
import threading
import mcrfpy
def background_worker():
with mcrfpy.lock(): # Blocks until safe
player.x = new_x # Safe to modify UI
threading.Thread(target=background_worker).start()
The lock works transparently from any context - background threads get
actual synchronization, main thread calls (callbacks, init) get no-op.

Implement the foundational HeightMap class for procedural generation:
- HeightMap(size, fill=0.0) constructor with libtcod backend
- Immutable size property after construction
- Scalar operations returning self for method chaining:
- fill(value), clear()
- add_constant(value), scale(factor)
- clamp(min=0.0, max=1.0), normalize(min=0.0, max=1.0)
Includes procedural generation spec document and unit tests.

McRogueFace needs to accept callable objects (properties on C++ objects)
and also support subclassing (getattr on user objects). Only direct
properties were supported previously, now shadowing a callback by name
will allow custom objects to "just work".
- Added CallbackCache struct and is_python_subclass flag to UIDrawable.h
- Created metaclass for tracking class-level callback changes
- Updated all UI type init functions to detect subclasses
- Modified PyScene.cpp event dispatch to try subclass methods
Major Timer API improvements:
- Add `stopped` flag to Timer C++ class for proper state management
- Add `start()` method to restart stopped timers (preserves callback)
- Add `stop()` method that removes from engine but preserves callback
- Make `active` property read-write (True=start/resume, False=pause)
- Add `start=True` init parameter to create timers in stopped state
- Add `mcrfpy.timers` module-level collection (tuple of active timers)
- One-shot timers now set stopped=true instead of clearing callback
- Remove deprecated `setTimer()` and `delTimer()` module functions
Timer callbacks now receive (timer, runtime) instead of just (runtime).
Updated all tests to use new Timer API and callback signature.

Replace module-level audio functions with proper OOP API:
- mcrfpy.Sound: Wraps sf::SoundBuffer + sf::Sound for short effects
- mcrfpy.Music: Wraps sf::Music for streaming long tracks
- Both support: volume, loop, playing, duration, play/pause/stop
- Music adds position property for seeking
Add mcrfpy.keyboard singleton for real-time modifier state:
- shift, ctrl, alt, system properties (bool, read-only)
- Queries sf::Keyboard::isKeyPressed() directly
Add mcrfpy.__version__ = "1.0.0" for version identity
Remove old audio API entirely (no deprecation - unused in codebase):
- createSoundBuffer, loadMusic, playSound
- setMusicVolume, getMusicVolume, setSoundVolume, getSoundVolume

The benchmark API captures per-frame data from the game loop, which is
bypassed when using step()-based simulation control. This warning
informs users to use Python's time module for headless performance
measurement instead.
Also adds test_headless_benchmark.py which verifies:
- step() and screenshot() don't produce benchmark frames
- Wall-clock timing for headless operations
- Complex scene throughput measurement

Implements Python-controlled simulation advancement for headless mode:
- Add mcrfpy.step(dt) to advance simulation by dt seconds
- step(None) advances to next scheduled event (timer/animation)
- Timers use simulation_time in headless mode for deterministic behavior
- automation.screenshot() now renders synchronously in headless mode
(captures current state, not previous frame)
This enables LLM agent orchestration (#156) by allowing:
- Set perspective, take screenshot, query LLM - all synchronous
- Deterministic simulation control without frame timing issues
- Event-driven advancement with step(None)

Implements ColorLayer and TileLayer classes with z_index ordering:
- ColorLayer: stores RGBA color per cell for overlays, fog of war, etc.
- TileLayer: stores sprite index per cell with optional texture
- z_index < 0: renders below entities
- z_index >= 0: renders above entities
Python API:
- grid.add_layer(type, z_index, texture) - create layer
- grid.remove_layer(layer) - remove layer
- grid.layers - list of layers sorted by z_index
- grid.layer(z_index) - get layer by z_index
- layer.at(x,y) / layer.set(x,y,value) - cell access
- layer.fill(value) - fill entire layer
Layers are allocated separately from UIGridPoint, reducing memory
for grids that don't need all features. Base grid retains walkable/
transparent arrays for TCOD pathfinding.

Add Python API for capturing performance data to JSON files:
- mcrfpy.start_benchmark() - start capturing frame data
- mcrfpy.end_benchmark() - stop and return filename
- mcrfpy.log_benchmark(msg) - add log message to current frame
The benchmark system captures per-frame data including:
- Frame timing (frame_time_ms, fps, timestamp)
- Detailed timing breakdown (grid_render, entity_render, python, animation, fov)
- Draw call and element counts
- User log messages attached to frames
Output JSON format supports analysis tools and includes:
- Benchmark metadata (PID, timestamps, duration, total frames)
- Full frame-by-frame metrics array
Also refactors ProfilingMetrics from nested GameEngine struct to
top-level struct for easier forward declaration.
