24 hoursfix: correct Heptagon effect rendering and SDF implementationskal
- Change draw call from 21 to 3 vertices (fullscreen triangle) - Replace broken folding-based SDF with IQ's atan-based regular polygon formula - Simplify test timeline to render Heptagon directly to sink - Reduce heptagon radius from 0.5 to 0.3 for better visibility The effect was not visible due to incorrect vertex count and broken SDF returning negative values everywhere (showing only fill color).

31 hoursfix: calculate beat_phase for FlashEffect and refactor uniformsskal
- seq_compiler.py: Calculate beat_phase from beat_time (was hardcoded 0.0f) - Refactor: Replace CommonPostProcessUniforms with UniformsSequenceParams - Remove duplicate struct definition in post_process_helper.h - Update all CNN effects and tests to use unified uniform struct - Fixes FlashEffect showing solid white instead of flashing to beat Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
33 hoursrefactor: remove v2 versioning artifacts, establish Sequence as canonical systemskal
Complete v1→v2 migration cleanup: rename 29 files (sequence_v2→sequence, effect_v2→effect, 14 effect files, 8 shaders, compiler, docs), update all class names and references across 54 files. Archive v1 timeline. System now uses standard naming with all versioning removed. 30/34 tests passing. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
36 hoursfeat(sequence): complete v2 migration with DAG-based routingskal
Phase 4 complete: V1 system removed, v2 fully operational.

Phase 5 (editor) deferred per user preference. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
38 hoursfeat(sequence): add inline post-process functions for v2skal
- Create postprocess_inline.wgsl with 7 inline effect functions - Functions: vignette, flash, fade, theme, solarize, chroma_aberration, distort - Add example combined_postprocess_v2.wgsl showing usage - Register postprocess_inline snippet with ShaderComposer - Add to main and test workspace assets - All tests passing (36/36) Strategy: Simple effects become inline functions instead of separate classes. Complex effects (rotating_cube, hybrid_3d, particles) remain as TODO for v2 port. handoff(Claude): Inline functions ready, 7 simple effects consolidated
39 hoursfeat(sequence): complete phase 3 - v2 shader integration and effect portsskal
- Create v2-compatible WGSL shaders with UniformsSequenceParams - Add sequence_v2_uniforms snippet for ShaderComposer - Port 3 effects: PassthroughEffectV2, GaussianBlurEffectV2, HeptagonEffectV2 - Enable and fix end-to-end test (test_sequence_v2_e2e) - Fix shader binding order (sampler at 0, texture at 1) - Fix WebGPU validation (maxAnisotropy=1, explicit depthSlice) - Add v2 shaders to main and test workspace assets - All tests passing (36/36) handoff(Claude): Phase 3 complete, v2 effects functional, ready for phase 4

3 daysfeat(gpu): add two-pass raymarching infrastructureskal
Add RayMarchResult struct and functions for deferred SDF rendering: - rayMarchWithID() tracks object ID and distance_max - reconstructPosition(), normalWithID(), shadowWithStoredDistance() - Pass 1: store geometry data, Pass 2: reuse for shading Add WGSL style rule: prefer return values over pointers for small structs (≤16 bytes).

3 daysfeat(gpu): add SDF camera infrastructure and effect base classskal
Add unified camera system for SDF raymarching effects: - CameraParams struct (80 bytes): inv_view matrix + FOV/near/far/aspect - SDFEffect base class: manages camera uniform, provides update_camera() helpers - camera_common.wgsl: getCameraRay(), position/forward/up/right extractors - SDFTestEffect: working example with orbiting camera + animated sphere Refactor effect headers: - Extract class definitions from demo_effects.h to individual .h files - Update includes in .cc files to use specific headers - Cleaner compilation dependencies, faster incremental builds Documentation: - Add SDF_EFFECT_GUIDE.md with complete workflow - Update ARCHITECTURE.md, UNIFORM_BUFFER_GUIDELINES.md - Update EFFECT_WORKFLOW.md, CONTRIBUTING.md Tests: 34/34 passing, SDFTestEffect validated Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
3 daysrefactor(wgsl): consolidate SDF shapes into single common fileskal
Merge sdf_primitives.wgsl into math/sdf_shapes.wgsl to eliminate duplication and establish single source of truth for all SDF functions. Changes: - Delete common/shaders/sdf_primitives.wgsl (duplicate of math/sdf_shapes.wgsl) - Add sdBox2D() and sdEllipse() to math/sdf_shapes.wgsl - Update ellipse.wgsl (main/test) to use #include "math/sdf_shapes" - Update scene1.wgsl to use math/sdf_shapes instead of sdf_primitives - Rename asset SHADER_SDF_PRIMITIVES → SHADER_SDF_SHAPES - Update shader registration and tests Impact: - ~60 lines eliminated from ellipse shaders - Single source for 3D primitives (sphere, box, torus, plane) and 2D (box, ellipse) - Consistent include path across codebase All tests passing (34/34). handoff(Claude): SDF shapes consolidated to math/sdf_shapes.wgsl Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
3 daysrefactor(wgsl): modularize common shader functionsskal
Extracted common WGSL functions into separate files in `common/shaders/` to improve reusability and maintainability. - Created `common/shaders/render/fullscreen_vs.wgsl` for a reusable fullscreen vertex shader. - Created `common/shaders/math/color.wgsl` for color conversion and tone mapping functions. - Created `common/shaders/math/utils.wgsl` for general math utilities. - Created `common/shaders/render/raymarching.wgsl` for SDF raymarching logic. - Updated multiple shaders to use these new common snippets via `#include`. - Fixed the shader asset validation test to correctly handle shaders that include the common vertex shader. This refactoring makes the shader code more modular and easier to manage.
5 daysRemediation: Implement shared common/shaders/ directoryskal
Eliminates 36 duplicate shader files across workspaces. Structure: - common/shaders/{math,render,compute}/ - Shared utilities (20 files) - workspaces/*/shaders/ - Workspace-specific only Changes: - Created common/shaders/ with math, render, compute subdirectories - Moved 20 common shaders from workspaces to common/ - Removed duplicates from test workspace - Updated assets.txt: ../../common/shaders/ references - Enhanced asset_packer.cc: filesystem path normalization for ../ resolution Implementation: Option 1 from SHADER_REUSE_INVESTIGATION.md - Single source of truth for common code - Workspace references via relative paths - Path normalization in asset packer handoff(Claude): Common shader directory implemented
