# To-Do List
**High-level task tracker.** See individual design docs for implementation details.
**Completed tasks:** `doc/COMPLETED.md`
---
## Priority 1: Spectral Brush Editor (Task #5) [IN PROGRESS]
Procedural spectrogram tool: 50-100× compression (5 KB .spec → ~100 bytes C++).
**Design:** `doc/SPECTRAL_BRUSH_EDITOR.md`
---
## ~~Priority 2: Workspace System (Task #77)~~ [COMPLETED]
Self-contained workspaces for parallel demo development.
**Design:** `doc/WORKSPACE_SYSTEM.md`
**Usage:** `cmake -B build -DDEMO_WORKSPACE=main`
---
## Priority 2: CNN v2 - Parametric Static Features (Task #85) [COMPLETE]
Enhanced CNN post-processing with multi-dimensional feature inputs.
**Design:** `doc/CNN_V2.md`
**Status:**
- ✅ Full implementation complete and validated
- ✅ Binary weight loading fixed (FATAL_CHECK inversion bug)
- ✅ Training pipeline: 100 epochs, 3×3 kernels, patch-based
- ✅ All tests passing (36/36)
**Specs:**
- 7D static features (RGBD + UV + sin + bias)
- Storage buffer weights (~3.2 KB, 8→4→4 channels)
- Dynamic layer count, per-layer params
- <10 KB target achieved
**TODO:** 8-bit quantization (2× reduction, needs QAT).
---
## Priority 3: Tracker Humanization & Sample Offset
Enhance tracker with sample offset and humanization for realistic playback.
**Features:**
1. **Sample Offset:** Intrinsic offset value per sample (shifts trigger left, preserves beat sync)
- Add `offset_sec` to `NoteParams` (gen.h) and `Sample` struct
- Extend `.track` SAMPLE syntax: `SAMPLE <name> [OFFSET <sec>] [VOL <vol>]`
- Apply negative `start_offset_samples` in `trigger_note_event()`
2. **Humanization:** Per-note random timing/volume variation (baked into WAV export)
- Add to `TrackerScore`: `humanize_seed`, `timing_variation_pct`, `volume_variation_pct`
- `.track` syntax: `HUMANIZE SEED <int> TIMING <pct> VOLUME <pct>`
- Apply per-event RNG modulation in `tracker_update()`
---
## Priority 4: 3D System Enhancements (Task #18)
Pipeline for importing complex 3D scenes to replace hardcoded geometry.
**Status:** C++ object data loading complete. Shader SDF integration pending.
---
## Priority 4: WGSL Modularization (Task #50) [RECURRENT]
Ongoing shader code hygiene for granular, reusable snippets.
---
## Future: Size Optimization (64k Target)
- Task #22: Windows Native Platform (Win32)
- Task #28: Spectrogram Quantization
- Task #34: Full STL Removal
- Task #35: CRT Replacement
**Measure:** `./scripts/measure_size.sh`
---
**Backlog:** `doc/BACKLOG.md` for untriaged ideas
