15 hoursfix: load rotating_cube_v2 shader from asset instead of empty stringskal
RotatingCubeEffect was failing with "Unable to find entry point 'vs_main'" because shader was hardcoded to empty string. Load from ASSET_SHADER_ROTATING_CUBE_V2. Fixes DemoEffectsTest (34/34 tests now pass). Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
15 hoursrefactor(gpu): remove depthSlice conditionals, use platform.h abstractionskal
WGPU_DEPTH_SLICE_UNDEFINED is defined unconditionally via platform.h (native headers or Win32 macro). Remove redundant conditional compilation from 7 effects and gpu.h helper. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

39 hoursfix(audio): WAV dump drift improvements, acceptable stateskal
WAV dump changes: - Bypass ring buffer, render directly with synth_render() - Frame accumulator eliminates truncation errors - Skip pre-fill and fix seek for WAV dump mode - Result: No glitches, -150ms drift at 64b (acceptable) Timeline editor: - Fix waveform tooltip position calculation - Increase beat bar visibility (0.5 opacity) Cleanup: - Remove all drift debugging code from audio.cc and tracker.cc Status: Acceptable for now, further investigation needed. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
41 hoursdocs: document audio WAV drift bug investigationskal
Root cause: audio_render_ahead() over-renders by 366ms per 10s, causing progressive timing drift in WAV files. Events appear early in viewer. Findings: - Renders 11,733 extra frames over 40s (331,533 vs 319,800 expected) - Ring buffer accumulates excess audio (~19 frames/iteration) - WAV dump reads exact 533 frames but renders ~552 frames per call - Results in -180ms drift at 60 beats visible in timeline viewer Debug changes: - Added render tracking to audio.cc to measure actual vs expected - Added drift printf to tracker.cc for kick/snare timing analysis - Added WAV sample rate detection to timeline viewer See doc/AUDIO_WAV_DRIFT_BUG.md for complete analysis and proposed fixes.

Implements two tracker realism features: 1. Sample Offset (compile-time): - Add offset_sec field to NoteParams and Sample structs - Parse OFFSET parameter in SAMPLE directive - Apply timing shift during compilation (zero runtime cost) - Use for attack-heavy samples to align perceived beat 2. Humanization (runtime, deterministic): - Add humanize_seed, timing_variation_pct, volume_variation_pct to TrackerScore - Parse HUMANIZE directive with SEED/TIMING/VOLUME params - Apply per-event RNG jitter using std::minstd_rand - Deterministic: same seed produces identical output Both features work in real-time playback and WAV export.
