docs: streamline timeline editor documentation

2026-02-17T07:04:01Z

Drastically reduce documentation verbosity while retaining essential info. README.md (152→82 lines): - Consolidated features into organized sections - Single concise v2 format example - Removed redundant explanations - Quick start section upfront ROADMAP.md (685→60 lines): - Completed features: simple bullet list - Future work: brief descriptions only - Removed verbose implementation details - Removed outdated sections Net reduction: -851 lines (-90%) Co-Authored-By: Claude Sonnet 4.5

docs: update timeline editor documentation for v2 format

2026-02-17T06:59:21Z

Updates all documentation to reflect Sequence V2 format support: Timeline Editor (tools/timeline_editor/): - README.md: Updated features list, file format examples with NODE declarations and arrow syntax, usage instructions for node editing - ROADMAP.md: Added completed item 1.0 "Sequence V2 Format Support" Core Documentation (doc/): - HOWTO.md: Updated timeline example to use v2 arrow syntax, added NODE/buffer chain features to visual editor description - SEQUENCE.md: Marked timeline editor graph visualization as completed All examples now show v2 format: EFFECT + ClassName input1 input2 -> output1 output2 start end Co-Authored-By: Claude Sonnet 4.5

feat: add Sequence V2 format support to timeline editor

2026-02-17T06:52:48Z

Implements full support for the sequence v2 DAG format with explicit node routing and arrow syntax. New features: - timeline-format.js module for parsing/serializing v2 format - NODE declarations with typed buffers (u8x4_norm, f32x4, etc.) - Arrow syntax for effect routing: input1 input2 -> output1 output2 - Buffer chain visualization in properties panel and tooltips - Node editor modal for adding/deleting node declarations - Validation for undeclared node references (when NODEs explicit) - Backward compatible with auto-inferred nodes Files added: - tools/timeline_editor/timeline-format.js (214 lines) - tools/timeline_editor/test_format.html (automated tests) - workspaces/test/timeline_v2_test.seq (test file with NODE declarations) Files modified: - tools/timeline_editor/index.html (~40 changes for v2 support) All success criteria met. Round-trip tested with existing timelines. handoff(Claude): Timeline editor now fully supports v2 format with explicit node routing, NODE declarations, and buffer chain visualization. Parser handles both explicit NODE declarations and auto-inferred nodes. Validation only runs when explicit NODEs exist. Ready for production use. Co-Authored-By: Claude Sonnet 4.5

refactor: remove C++ seq_compiler and Gantt chart references

2026-02-16T20:51:05Z

- Remove tools/seq_compiler.cc (replaced by seq_compiler.py) - Remove C++ seq_compiler build target from cmake/DemoTools.cmake - Update documentation to remove Gantt chart mentions - Keep seq_compiler.py (active Python compiler) - All tests passing (34/34)

refactor(tools): consolidate common CSS for HTML tools

2026-02-15T16:09:57Z

Extract common styles from various tool HTML files (timeline, spectral, cnn_v2_test, etc.) into a shared stylesheet. This reduces code duplication and improves maintainability of the tool frontends. - Create a new 'tools/common/style.css' to house the shared rules. - Update all tool HTML files to link to the new stylesheet. - Remove redundant inline styles from individual HTML files.

fix(audio): WAV dump drift improvements, acceptable state

2026-02-15T15:41:08Z

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.

fix(timeline-editor): correct waveform tooltip position calculation

2026-02-15T15:15:38Z

Remove TIMELINE_LEFT_PADDING offset from waveform cursor calculation. mouseX is already relative to waveform container, no padding adjustment needed. Co-Authored-By: Claude Sonnet 4.5

fix(timeline-editor): capture all wheel events at container level

2026-02-15T14:23:21Z

- Add timelineContainer reference and capture wheel events with { capture: true } - Remove redundant wheel handlers from individual sequence/effect elements - Prevents child elements from interfering with zoom/scroll functionality Co-Authored-By: Claude Sonnet 4.5

docs(timeline-editor): clarify effect time units in property panel

2026-02-15T14:20:17Z

Add "beats" to start/end time labels in effect properties panel for consistency with sequence panel. Co-Authored-By: Claude Sonnet 4.5

refactor(timeline-editor): complete variable unit renames in modules

2026-02-15T14:18:42Z

- newPixelsPerSecond → newPixelsPerBeat - maxTime → maxTimeBeats (in waveform render) Co-Authored-By: Claude Sonnet 4.5
