Turn SampleBrain into a reproducible, genre-aware sample analysis system without committing audio or local state.
- Repo hygiene (.gitignore enforced)
- PROJECT_META.md as single source of truth
- Deterministic feature extraction only (no ML training yet)
- Weak ground truth from filenames & folders
- BPM / Key confidence reports
- Error buckets (half/double BPM, key ambiguity)
- Per-genre config (Techno, Cinematic, LoFi…)
- Seeds + thresholds, not heavy ML
- Optional embeddings later
No model training before validation passes.
