 ## Project Roadmap
 
-### Next Up
-- **Task #25: Build System Consolidation**:
-    - [ ] Create static/dynamic libraries for subsystems (audio, gpu, 3d, util) to improve modularity.
-    - [ ] Refactor `CMakeLists.txt` using macros to reduce boilerplate and repetitive clauses.
-    - [ ] Consolidate host-tool build logic (asset_packer, etc.) into a unified helper.
-
-- **Task #20: Code & Platform Hygiene**
+### Recently Completed
+- **Build System Consolidation (Task #25)**: Modularized the build by creating subsystem libraries (audio, gpu, 3d, util, procedural) and implemented helper macros to reduce boilerplate in `CMakeLists.txt`. This improves build maintenance and prepares for future CRT replacement.
+- **Asset System Robustness**: Resolved "static initialization order fiasco" by wrapping the asset table in a "Construct On First Use" getter (`GetAssetRecordTable()`), ensuring assets are available during dynamic global initialization (e.g., shader strings).
     - [ ] Gather all cross-compile and platform-specific conditional code into `platform.h`.
     - [ ] Refactor `platform_init()` and `platform_poll()` for cleaner abstraction.
     - [ ] Consolidate WebGPU header inclusions.

 This file tracks prioritized tasks with detailed attack plans.
 
-## Priority 1: Build System Consolidation (Task #25)
-**Goal:** Modularize the project and simplify CMake maintenance.
-- [ ] **Attack Plan - Subsystem Libraries:** Group source files into static libraries (`audio`, `gpu`, `3d`, `util`) to reduce link line complexity.
-- [ ] **Attack Plan - CMake Macros:** Implement `add_demo_library` and `add_demo_executable` macros to handle platform-specific definitions and warnings uniformly.
-- [ ] **Attack Plan - Host Tool Helpers:** Consolidate code generation targets into a single CMake helper.
-
-## Priority 2: Platform & Code Hygiene (Task #20)
+## Recently Completed
+- [x] **Build System Consolidation (Task #25)**: Modularized the build into subsystem libraries and implemented helper macros to simplify CMake maintenance.
+- [x] **Asset System Robustness**: Fixed static initialization order issues by wrapping the asset table in a singleton-style getter (`GetAssetRecordTable()`).
 **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(...)`.
