# To-Do List
This file tracks prioritized tasks with detailed attack plans.
## Priority 1: Final Build Stripping (Task #8)
**Goal:** Reduce binary size by removing all non-essential code under the `STRIP_ALL` macro.
- [ ] **Attack Plan - Rules:** Document stripping rules in `doc/STRIPPING.md`.
- [ ] **Attack Plan - Error Strings:** Wrap all non-critical `printf`, `std::cerr`, and error strings in `STRIP_ALL`.
- [ ] **Attack Plan - CLI Parsing:** Disable all non-essential CLI arguments (seek, resolution, debug) in `STRIP_ALL`.
- [ ] **Attack Plan - Struct Hygiene:** Remove debug-only fields (like `label` or `name`) from core structs.
## Priority 2: Platform & Code Hygiene (Task #20)
**Goal:** Clean up the codebase for easier cross-platform maintenance and CRT replacement.
- [ ] **Attack Plan - Header Consolidation:** Move all `#ifdef` logic for WebGPU headers and platform-specific shims into `src/platform.h`.
- [ ] **Attack Plan - Refactor platform_init:** Change `void platform_init(PlatformState* state, ...)` to `PlatformState platform_init(...)`.
- [ ] **Attack Plan - Unified Poll:** Incorporate `platform_get_time()` and `platform_get_aspect_ratio()` updates into `platform_poll()`.
- [ ] **Attack Plan - Standard Container Removal:** Replace `std::map`, `std::string`, and `std::vector` in performance-critical or size-sensitive paths with simpler C-style alternatives.
## Priority 3: Shader Optimization (Task #21)
**Goal:** Improve GPU performance and reduce shader source bloat.
- [ ] **Attack Plan - Normal Factorization:** Create a standard WGSL helper for normal calculation to avoid duplicate code in every effect.
## Future Goals
- [ ] **Task #5: Spectrogram Editor**: Web-based visual tool for extreme audio compression.
- [ ] **Task #18: 3D System Enhancements**: Blender exporter and GPU-based BVH for complex scenes.
- [ ] **Task #22: Windows Native Platform**: Replace GLFW with direct Win32 API calls for the final 64k push.
- [ ] **Task #23: Shader Performance Analysis**: Analyze shader performance using Xcode Metal debugger on macOS.
## Phase 2: Advanced Size Optimization
- [ ] **Task #8**: Implement Final Build Stripping
## Recently Completed
- [x] **WGSL Library (Task 21.1)**: Implemented ShaderComposer for modular WGSL snippet management.
- [x] **Tight Ray Bounds (Task 21.2)**: Derived t_min and t_max from proxy hull hits via local-space ray-box intersection.
- [x] **Math & Unit Tests**: Added rigorous matrix inversion checks and ShaderComposer verification tests.
- [x] **High-DPI Fix**: Resolved viewport "squishing" via dynamic resolution uniforms and explicit viewports.
- [x] **Unified 3D Shadows**: Implemented robust SDF shadows across all objects using `inv_model` transforms.
- [x] **Tight Proxy Hulls**: Optimized Torus proxy geometry and debug wireframes.
- [x] **Procedural Textures**: Restored floor grid and SDF bump mapping.
- [x] **Code Hygiene**: Completed a project-wide code formatting pass with `clang-format`.
