- overlay.fps: SDL software renderer → GPU texture quad, top-right corner,
yellow EMA-smoothed FPS counter; LOADOP_LOAD preserves scene beneath it
- debug.screenshot: one-shot step that writes status txt + BMP then pushes
SDL_EVENT_QUIT for automated visual feedback loop
- Adaptive vsync: graphics.gpu.init "auto" present_mode queries actual monitor
refresh rate via SDL_GetCurrentDisplayMode; ≥120 Hz → VSYNC, <120 Hz → MAILBOX
Fixes vsync cap on 165/170 Hz monitors reporting as 240 Hz in settings
- Fixed present_mode wiring: q3_game.json gpu_init_viewport node now passes
present_mode as a direct parameter (workflow variables are not seeded into
context by the executor, so the variable section was dead data)
- Stair climbing: probeReach 0.45→0.70 for earlier detection, jam detection
nudges player up after 100 ms of horizontal blockage, step_height tuned to 0.6
- Physics dt: real wall-clock delta clamped to [1/600, 1/30] so 240 Hz displays
don't run physics 4× faster than intended
- GUI smart search paths: _candidate_build_dirs() scans all generator dirs ×
build types × flat and Conan-nested layouts, sorted by CMakeCache.txt mtime;
_find_binary() picks freshest sdl3_app.exe; packages loaded relative to
__file__ so gui works from any working directory

Workflow JSON params can now reference environment variables (e.g.
${env:QUAKE3_PAK0}) which are expanded at JSON load time. A new Python
detector reads the Windows registry and parses libraryfolders.vdf to
locate Steam libraries, then resolves known-game files into env vars
that dev_commands.py exports before launching the engine. Lets users
with legitimate Steam-owned game data run packages like quake3 without
hardcoded paths.
Also fixes os.execv on Windows (Invalid argument with spaced paths) by
falling back to subprocess.call.

When Conan's build output layout changes (e.g. build/generators/ vs
build/Release/generators/), CMakeUserPresets.json accumulates includes
that define the same preset names, causing CMake to fail with
"Duplicate preset". The fix detects preset name collisions across
included files and keeps only the newest, in addition to pruning
missing files.

Add explicit search paths for python.org installer (%APPDATA%\Python),
Chocolatey, macOS system Python (~/Library/Python), and ~/.local/bin.
Document coverage matrix for Windows (Store/python.org/Chocolatey),
macOS (Homebrew/system/pyenv), and Linux (apt/dnf/pip --user).

Searches PATH, interpreter/user Scripts dirs, site-packages sibling
dirs, and falls back to module invocation. Covers system Python,
Homebrew, Windows Store Python, pyenv, conda, pip --user, and venvs.

Windows Store Python installs packages without adding Scripts to PATH,
causing FileNotFoundError when invoking conan directly.

- map.load: Assimp-based glTF/GLB scene loader with auto physics generation
- draw.map: renders all map meshes with JSON-driven texture-to-mesh mapping
- export_room_gltf.py: exports seed workflow physics bodies to GLB
- Seed demo room exported as map.glb (14 static meshes)
- Texture mapping configurable per mesh name pattern in workflow JSON
- Maps can be edited in Blender and re-exported

Build system:
- Fix generate_cmake.py backslash paths and UTF-8 encoding for Windows
- Auto C++20 in conan deps, auto-detect VS install location
- dev_commands.py: add generate, all --run commands, platform-aware bootstrap
- Add assimp to cmake_config.json link libraries
- Fix CMakeUserPresets.json duplicate preset issue
Cross-platform C++:
- UUID generation: Windows rpc.h/UuidCreate with #ifdef _WIN32
- HOME env var fallback to USERPROFILE on Windows
- Shader format detection for D3D12/DXIL Vulkan driver
Shader pipeline (12 new SPIRV shaders):
- Port all Metal shaders to Vulkan GLSL (PBR, shadows, post-FX, compute)
- SDL3 GPU descriptor set convention (set 0-3)
- Combined image samplers for Vulkan compatibility
- Bootstrap-driven shader path rewriting (msl↔spirv automatic per platform)
Rendering features:
- spotlight.setup: generic atomic workflow step, attach to camera or static
- PBR spotlight with cone attenuation, distance falloff, wrap lighting
- Volumetric light beam (16-step ray march through dust/fog in spotlight cone)
- geometry.create_flashlight: procedural flashlight mesh (cylinder + head + lens)
- draw.viewmodel: FPS weapon-style rendering locked to camera view
- model.load: Assimp-based 3D model loader (OBJ/GLB/FBX/BLEND)
- Indoor ambient lighting fix, SSAO bypass for Vulkan clip-space
Performance:
- Frame loop logging suppressed via _in_frame_loop context flag
Assets:
- Real PBR textures from ambientCG (CC0): wood floor, concrete ceiling
- Seed demo: dark room + flashlight beam + Quake-style viewmodel

Remove stale dirs/files superseded by metabuilder-small's reorganization:
- Old YAML entity/seed files (migrated to JSON)
- Root-level workflowui/ (moved to frontends/workflowui/)
- Prisma, Pyodide, old hooks, bun.lock artifacts
- Legacy scratch docs (txt/, docs/, deployment/*.md)
- Stale CI workflows consolidated in small

Import SDL3CPlusPlus C++ game engine with:
- SDL3 + bgfx rendering backend
- Vulkan/Metal/DirectX shader support
- MaterialX material system
- Scene framework with ECS architecture
- Comprehensive test suite (TDD approach)
- Conan package management
- CMake build system
This provides the native C++ foundation for the Universal Platform's
Game and 3D capability modules.
