- ra3.dx: D3D11 and D3D12 presentation backends (runtime HLSL via d3dcompiler);
2D image blit and the GPU heightfield terrain raymarch, with the corner
minimap/FPS overlays. Non-Windows builds link a null fallback.
- ra3.display: preferred backend plus ordered fallback (Vulkan/D3D11/D3D12/SDL);
menu gains a Renderer option and the CLI gains --dx11/--dx12/--sdl, which the
render command now honours too.
- vendor libenderlog (MIT): every run writes openra3.log next to the exe and
archives the previous run's log; records at warn and above carry a call stack
(native fallback, since libc++ has no <stacktrace>).
- Windows crash reporter writes openra3_crash.log (faulting module + backtrace);
D3D/DXGI diagnostics are routed through the logger.
Decompose the full Red Alert 3 feature set three levels deep (29 modules, 169 functions, ~500 features) with per-feature status and milestone tags. Fold the release roadmap into ARCHITECTURE section 5 and remove docs/ROADMAP.md.
