ans: order-0 rANS coder + WGSL asset compression

2026-05-14T17:11:28Z

Adds src/util/ans.{h,cc}, a per-chunk-adaptive order-0 rANS entropy coder. Decoder is always built; encoder is gated on ANS_ENABLE_ENCODER (tools only). Both sides take an optional 256-entry initial_counts table to seed the adaptive model. The per-chunk initial state is (1 << kBits). Higher initial states (e.g. with a signature packed into the upper bits) force a renorm-emit at iter 0 that the decoder never consumes, corrupting multi-chunk streams once stats become skewed. Asset pipeline: - AssetRecord gains 'compression' and 'uncompressed_size' fields. - asset_packer scans every WGSL file to build a corpus-wide byte histogram, then ANS-encodes each shader using that histogram as the seed. Histogram and accessor are emitted alongside the asset table. Round-trip verification runs at pack time for every compressed asset; failures fall back to uncompressed storage. - asset_manager decompresses on first GetAsset(), caches the heap-allocated buffer, and DropAsset / ReloadAssetsFromFile free it along with the procedural cache. - Disk-load (dev) builds are unchanged: WGSL paths stay as filenames. Tests: - src/tests/util/test_ans.cc: roundtrip variants (empty, single byte, single-symbol run, all-zeros, random uniform/skewed, repeated ASCII), seeded-vs-uniform compression, rejection of mismatched counts / corruption / truncation, PeekUncompressedSize. - 37/37 dev, 36/36 STRIP_ALL. Compression observed: WGSL shaders shrink to ~0.62-0.71x in the main workspace (81 of 105 assets qualify). Docs: - doc/ANS.md (new): algorithm, bitstream, API, asset pipeline integration, compression numbers, limitations, tests. - doc/ASSET_SYSTEM.md: new Compression section + updated technical guarantees for compressed assets. - doc/COMPLETED.md: May 2026 entry. - PROJECT_CONTEXT.md: Build status line mentions WGSL ANS compression. - CLAUDE.md, GEMINI.md: tier-3 build doc list includes ANS.md.

feat(procedural): add plasma, voronoi, normalmap generators

2026-03-29T00:42:28Z

Add three new procedural texture generators: - gen_plasma: classic sine-sum color texture (RGB output) - gen_voronoi: Worley cellular noise (F1/F2/F2-F1 modes) - gen_normalmap: post-process grayscale→RGB normal map Remove gen_noise_256 (was an alias for gen_noise). Register new generators in asset_manager and asset_packer. Add unit tests for all three, and use them in test_3d_render (plasma sky, voronoi noise, fBm normal map). handoff(Gemini): plasma/voronoi/normalmap procedural generators added; gen_noise_256 removed; tests + 3d_render usage wired up.

feat: Move test_platform.cc to util subdirectory

2026-02-14T13:35:54Z

Moved to to better organize test files. Updated to reflect the new file location. All tests pass after the move and build system update.

Factor common test patterns into reusable utilities

2026-02-14T01:39:49Z

Refactor duplicated test setup/teardown code into shared fixtures: - test_math_helpers.h: Float comparison (test_near, test_near_vec3) - AudioTestFixture: RAII wrapper for AudioEngine lifecycle - EffectTestFixture: Combined WebGPU + AudioEngine + MainSequence Migrated 9 test files (3 math, 6 audio) to use fixtures. Net reduction: 54 LOC (178 insertions, 232 deletions). All 34 tests passing. Co-Authored-By: Claude Sonnet 4.5

refactor: Reorganize tests into subsystem subdirectories

2026-02-09T19:27:04Z

Restructured test suite for better organization and targeted testing: **Structure:** - src/tests/audio/ - 15 audio system tests - src/tests/gpu/ - 12 GPU/shader tests - src/tests/3d/ - 6 3D rendering tests - src/tests/assets/ - 2 asset system tests - src/tests/util/ - 3 utility tests - src/tests/common/ - 3 shared test helpers - src/tests/scripts/ - 2 bash test scripts (moved conceptually, not physically) **CMake changes:** - Updated add_demo_test macro to accept LABEL parameter - Applied CTest labels to all 36 tests for subsystem filtering - Updated all test file paths in CMakeLists.txt - Fixed common helper paths (webgpu_test_fixture, etc.) - Added custom targets for subsystem testing: - run_audio_tests, run_gpu_tests, run_3d_tests - run_assets_tests, run_util_tests, run_all_tests **Include path updates:** - Fixed relative includes in GPU tests to reference ../common/ **Documentation:** - Updated doc/HOWTO.md with subsystem test commands - Updated doc/CONTRIBUTING.md with new test organization - Updated scripts/check_all.sh to reflect new structure **Verification:** - All 36 tests passing (100%) - ctest -L filters work correctly - make run__tests targets functional - scripts/check_all.sh passes Backward compatible: make test and ctest continue to work unchanged. handoff(Gemini): Test reorganization complete. 36/36 tests passing.
