UI badge updates automatically. + +## Consequences + +### Positive +- Users can train a model on **their own environment** without external tools or Python dependencies. +- LoRA profiles mean a single base model adapts to multiple rooms in minutes, not hours. +- Training progress is visible in real-time — no black-box waiting. +- A/B comparison lets users see the quality jump from signal-derived to model-inference. +- RVF container bundles everything (weights, metadata, LoRA, witness) in one portable file. +- Self-supervised pretraining requires no labels — just leave ESP32s running. +- Progressive loading means the UI is never "loading..." — signal-derived kicks in immediately. + +### Negative +- Training requires significant compute: GPU recommended for supervised training (CPU possible but 10-50x slower). +- MM-Fi and Wi-Pose datasets must be downloaded separately (10-50 GB each) — cannot be bundled. +- LoRA rank must be tuned per environment; too low loses expressiveness, too high overfits. +- ONNX Runtime adds ~50 MB to the binary size when GPU support is enabled. +- Real-time inference at 10 FPS requires ~10ms per frame — tight budget on CPU. +- Teacher-student labeling (camera → pose labels → CSI training) requires camera access, which may conflict with the privacy-first premise. + +### Mitigations +- Provide pre-trained base `.rvf` model downloadable from releases (trained on MM-Fi + Wi-Pose). +- INT8 quantization (`SEG_QUANT`) reduces model size 4x and speeds inference ~2x on CPU. +- Camera-based labeling is **optional** — self-supervised pretraining works without camera. +- Training API validates VRAM availability before starting GPU training; falls back to CPU with warning. + +## Implementation Order + +| Phase | Effort | Dependencies | Priority | +|-------|--------|-------------|----------| +| 1.1 CSI Recording API | 2-3 days | sensing server | High | +| 1.2 Contrastive Pretraining | 3-5 days | ADR-024, recording API | High | +| 2.1 Dataset Integration | 3-5 days | ADR-015, CsiDataset trait | High | +| 2.2 Training API | 2-3 days | training crate, dataset loaders | High | +| 2.3 RVF Export | 1-2 days | RvfBuilder | Medium | +| 3.1 LoRA Fine-Tuning | 3-5 days | base trained model | Medium | +| 3.2 Profile Switching | 1 day | LoRA in RVF | Medium | +| 4.1 Model Panel UI | 2-3 days | models API | High | +| 4.2 Training Dashboard UI | 3-4 days | training API + WS | High | +| 4.3 Live Demo Enhancements | 2-3 days | model loading | Medium | +| 4.4 Settings Extensions | 1 day | model/training APIs | Low | +| 4.5 Dark Mode | 0.5 days | new panels | Low | +| 5.1 Inference Wiring | 3-5 days | ONNX backend, pose tracker | High | +| 5.2 Progressive Loading | 2-3 days | ADR-031 | Medium | + +**Total estimate: 4-6 weeks** (phases can overlap;
