The fullscreen post-process VS uses Y-up UVs (uv.y=0 = bottom), so
textureSample() Y-flips any rasterized offscreen texture. SDF effects
author their content Y-down and look correct after the flip. Rasterized
effects (RotatingCube, Hybrid3D) must pre-flip their geometry:
- mat4::perspective(): m[5] = -t (negated Y scale)
- Pipelines with cullMode=Back: frontFace = WGPUFrontFace_CW (Y-flip
reverses winding, so CW becomes the visible face)
- Remove incorrect transposes from GlobalUniforms::make(),
ObjectData::make(), and Uniforms::make() — mini_math is column-major,
no transpose needed for GPU upload
- Document the convention in doc/3D.md under "Rasterized 3D and the
Y-flip rule"
handoff(Gemini): Y-flip rule now documented; all rasterized 3D pipelines
must follow it.

WGSL shaders now join SPEC/MP3 in being loaded from disk in development
mode, enabling shader iteration without rebuild.

This commit introduces a dual-mode asset loading system to enhance developer workflow and optimize release builds.
Key changes include:
- **Dual-Mode Asset Loading:** Assets are now loaded from disk during development (when is OFF) for faster iteration, particularly for heavy assets like and files. For release builds ( ON), all assets are embedded directly into the binary, ensuring a single, self-contained executable.
- **Explicit Asset Typing:** Replaced generic asset type with specific types (, , , , ) in and the enum in for clearer categorization and more robust processing.
- **Build System Integration:** Modified to pass a flag to in development builds.
- **Asset Packer Updates:** now generates file paths for disk-loaded assets and embeds data for others based on the build mode.
- **Asset Manager Enhancements:** includes new logic in for loading and caching disk-based assets and updates to for proper memory deallocation.
- **Documentation:** Updated to reflect the new asset nomenclature and dual-mode loading strategy.
- **Project Rules:** Added a concise rule to mandating top-level documentation updates for medium/large sub-system changes.
handoff(Gemini): Implemented dual-mode asset loading and updated documentation.

Replace boilerplate .h/.cc pairs for simple single-pass effects with a
generic WgslEffect base class that takes a shader string + optional
WgslEffectParams (binding 3). Port Flash, Passthrough, Heptagon, Scratch,
and GaussianBlur to thin header-only wrappers — no .cc files, no CMake
entries needed. Removes 5 .cc files (-243 lines).
Update EFFECT_WORKFLOW.md, CONTRIBUTING.md, and AI_RULES.md to document
the WgslEffect (Path A) vs full class (Path B) workflow. Doc cleanup:
fix stale GaussianBlurParams/PostProcessEffect references and test counts.
handoff(Claude): WgslEffect landed; 5 effects ported; docs updated.

snippet
- src/shaders/render/scratch_lines.wgsl: reusable WGSL snippet registered as
"render/scratch_lines"; call scratch_lines(uv, resolution, time)->f32 from
any effect. Uses hash_1f from math/noise; 8 lines/frame, ~24fps flicker.
- src/effects/scratch.{wgsl,h,cc}: thin Scratch effect wrapping the snippet.
- Applied to "intro" and "rotating_cube" sequences as the final step.
- 35/35 tests passing.
handoff(Gemini): Scratch effect added. render/scratch_lines snippet is reusable.

- Remove erroneous Hann synthesis window from synth.cc (g_hann * tmp[j]).
Hann analysis at 50% overlap satisfies w[n]+w[n+H]=1, so rectangular
synthesis gives perfect reconstruction; applying Hann twice was wrong.
- Extract ola_encode()/ola_decode()/ola_num_frames() into src/audio/ola.h+cc.
spectool and test_wav_roundtrip now use the shared functions.
synth.cc lazy-decode path stays inlined (see TODO for future refactor).
- Drop dead <atomic> include and g_hann array from synth.cc.
- Drop dead window.h include from spectool.cc.
- Update PROJECT_CONTEXT.md, COMPLETED.md, TODO.md to reflect correct
analysis-only Hann window and new ola.h API.
handoff(Gemini): OLA synthesis bug fixed + ola.h factorized. synth.cc
lazy-decode still inline (TODO item added). 34/35 tests pass; WavDumpBackendTest
failure is pre-existing and unrelated.

- spectool --wav <input.spec> <output.wav>: decodes .spec to mono 16-bit
WAV at 32 kHz using IDCT-OLA synthesis (no synthesis window).
The analysis Hann window at 50% overlap satisfies w[n]+w[n+H]=1,
so the synthesis window must be rectangular for perfect reconstruction.
- Add imdct_512 / imdct_fft to audio lib (fft.cc, fft.h, idct.cc, dct.h)
for future MDCT-based synthesis.
- test_wav_roundtrip: in-process OLA analyze+decode SNR test (≥30 dB).
Currently measures 53 dB on a 440 Hz sine.
- Fix stale test_spectool.cc: version assertion updated from 1 to
SPEC_VERSION_V2_OLA (was always wrong since OLA fix landed).
- Docs: TOOLS_REFERENCE.md removes dead specview, documents --wav /
--normalize / test_gen. HOWTO.md adds decode section. TRACKER.md
notes spec v2 OLA format and decode command.

Two bugs kept the v2 OLA path permanently disabled:
1. SpectrogramResourceManager::load_asset() never set spec.version from
SpecHeader::version — all .spec assets loaded with version=0, so
ola_mode was always false in the voice.
2. spectool analyze_audio() used non-overlapping chunks (stride=DCT_SIZE),
hamming_window_512, and hardcoded header.version=1 — OLA analysis was
never implemented in the encoder.
Fixes: propagate header->version in load_asset(); switch spectool to
OLA_HOP_SIZE stride, hann_window_512, and SPEC_VERSION_V2_OLA.
Regenerated all .spec files.
handoff(Gemini): OLA enc/dec chain now correct end-to-end. .spec files
are v2 (50% overlap, Hann). No API changes; 33/34 tests pass
(WavDumpBackendTest pre-existing failure unrelated).

enum, add MP3 type
- Add AssetType enum {STATIC, PROC, PROC_GPU, MP3} to AssetRecord
- Add GetAssetType() API to asset_manager.h/cc
- asset_packer: parse 'MP3' compression keyword in assets.txt
- tracker: remove magic-byte is_mp3_asset(); use GetAssetType() instead
- assets.txt: NEVER_MP3 now uses 'MP3' compression type
- doc/ASSET_SYSTEM.md: rewritten to document new types and API
handoff(Gemini): AssetType enum landed; MP3 detection is now explicit via asset metadata.

spectool was missing from DemoTools.cmake; scripts/gen_spectrograms.sh
could not find build/spectool. Document the regeneration workflow in HOWTO.md.
handoff(Claude): spectool now builds with -DDEMO_BUILD_TOOLS=ON
|
|
- PROJECT_CONTEXT: audio section reflects OLA-IDCT (Hann, 50% overlap);
test count 35->34; Next Up notes .spec regen needed
- TODO: remove stale MP3 sub-task (done), trim test TODOs, add .spec
regen as Priority 3, update test count to 34/34
- COMPLETED: archive OLA-IDCT task with implementation summary

Detect MP3 blobs by magic bytes in tracker_init(), decode to spectrogram
(hamming window + FDCT) using new mp3_decode(), and register with synth
exactly like .spec assets. STRIP_ALL builds guard with FATAL_CHECK.
handoff(Gemini): MP3 assets now usable in music.track with SAMPLE ASSET_*
syntax; see doc/TRACKER.md for usage. No synth/compiler/packer changes.

src/effects/
Move 13 effect-specific shaders from workspaces/main/shaders/ to src/effects/
so each effect's .h, .cc, and .wgsl are together. Update assets.txt paths in
both main and test workspaces. Update EFFECT_WORKFLOW.md to reflect new location.
Shared/reusable snippets remain in src/shaders/.
handoff(Gemini): shaders moved; src/effects/ now has .h, .cc, and .wgsl per effect.

Replaces all instances of `vec<f32>` with the more concise `vec*f` alias (e.g., `vec3f`) across all `.wgsl` shaders. This improves readability and aligns with common graphics programming conventions.
Also adds a new coding style rule to `doc/CODING_STYLE.md` to enforce this standard going forward.
Finally, this commit fixes a build error in `test_effect_base.cc` by replacing a call to the non-existent `wgpuDeviceTick` with `wgpuDevicePoll`, which resolves the test failure.

Factorizes the screen coordinate calculation from scene1.wgsl into a reusable getScreenCoord function in common/shaders/math/common_utils.wgsl.
This improves code reuse and simplifies fragment shaders.
|

- Add Scene1 effect: raymarching cube+sphere+ground (reflections, shadows)
- Fix scene1.wgsl: binding 0→2, CommonUniforms→UniformsSequenceParams
- Replace Heptagon+Placeholder stub in heptagon_scene with Scene1
- Fix seq_compiler.py: emit seq.start_time+effect.start/end (absolute times)
so dispatch_render active check works correctly for all sequences
Bug: effects in sequences starting after t=0 were never active because
local times (e.g. 0-8) never satisfied params.time<end for absolute time 20+.
34/34 tests passing.
handoff(Gemini): seq_compiler now emits absolute effect times. All existing
sequences affected — verify visual output across the full timeline.
