Sequences defined in beats, converted to seconds at runtime. Effects receive both physical time (constant) and beat time (musical). Variable tempo affects audio only. See `doc/BEAT_TIMING.md`. - **Workspace system:** Multi-workspace support. Easy switching with `-DDEMO_WORKSPACE=<name>`. Organized structure: `music/`, `weights/`, `obj/`, `shaders/`. Shared common shaders in `src/shaders/`. See `doc/WORKSPACE_SYSTEM.md`. -- **Audio:** Sample-accurate sync. Zero heap allocations per frame. Variable tempo. Comprehensive tests. +- **Audio:** Sample-accurate sync. Zero heap allocations per frame. Variable tempo. OLA-IDCT synthesis (v2 .spec): Hann window, 50% overlap, click-free. V1 (raw DCT-512) preserved for compatibility. MP3→spec encoder updated to match. Existing .spec files need regen to activate v2. - **Shaders:** Parameterized effects (UniformHelper, .seq syntax). Beat-synchronized animation support (`beat_time`, `beat_phase`). Modular WGSL composition with ShaderComposer. 24 shared common shaders (math, render, compute). - **3D:** Hybrid SDF/rasterization with BVH. Binary scene loader. Blender pipeline. - **Effects:** CNN post-processing: CNNEffect (v1) and CNNv2Effect operational. CNN v2: sigmoid activation, storage buffer weights (~3.2 KB), 7D static features, dynamic layers. Training stable, convergence validated. - **Tools:** CNN test tool operational. Texture readback utility functional. Timeline editor (web-based, beat-aligned, audio playback). - **Build:** Asset dependency tracking. Size measurement. Hot-reload (debug-only). WSL (Windows 10) supported: native Linux build and cross-compile to `.exe` via `mingw-w64`. - **Sequence:** DAG-based effect routing with explicit node system. Python compiler with topological sort and ping-pong optimization. 10 effects operational (Passthrough, Placeholder, GaussianBlur, Heptagon, Particles, RotatingCube, Hybrid3D, Flash, PeakMeter, Scene1). Effect times are absolute (seq_compiler adds sequence start offset). See `doc/SEQUENCE.md`. -- **Testing:** **35/35 passing**.
