+# ADR-055: Integrated Sensing Server in Desktop App
+
+## Status
+Accepted
+
+## Context
+The RuView Desktop application (ADR-054) requires the WiFi sensing server to provide real-time CSI data, activity detection, and vital signs monitoring. Currently, the sensing server is a separate binary (`wifi-densepose-sensing-server`) that must be installed separately and found in the system PATH.
+
+This creates several problems:
+1. **Distribution complexity**: Users must install two binaries
+2. **Path issues**: Binary may not be in PATH, causing "No such file or directory" errors
+3. **Version mismatch**: Server and desktop app versions may diverge
+4. **Poor UX**: Error messages about missing binaries confuse users
+
+## Decision
+Bundle the sensing server binary inside the desktop application and provide intelligent binary discovery with clear fallback paths.
+
+### Binary Discovery Order
+The desktop app searches for the sensing server in this order:
+1. **Custom path** from user settings (`server_path`)
+2. **Bundled resources** (`Contents/Resources/bin/` on macOS)
+3. **Next to executable** (same directory as the app binary)
+4. **System PATH** (legacy fallback)
+
+### Implementation
+```rust
+fn find_server_binary(app: &AppHandle, custom_path: Option<&str>) -> Result<String, String> {
+    // 1. Custom path from settings
+    if let Some(path) = custom_path {
+        if std::path::Path::new(path).exists() {
+            return Ok(path.to_string());
+        }
+    }
+
+    // 2. Bundled in resources
+    if let Ok(resource_dir) = app.path().resource_dir() {
+        let bundled = resource_dir.join("bin").join(DEFAULT_SERVER_BIN);
+        if bundled.exists() {
+            return Ok(bundled.to_string_lossy().to_string());
+        }
+    }
+
+    // 3. Next to executable
+    if let Ok(exe_path) = std::env::current_exe() {
+        if let Some(exe_dir) = exe_path.parent() {
+            let sibling = exe_dir.join(DEFAULT_SERVER_BIN);
+            if sibling.exists() {
+                return Ok(sibling.to_string_lossy().to_string());
+            }
+        }
+    }
+
+    // 4. System PATH
+    // ... which lookup ...
+
+    Err("Sensing server binary not found")
+}
+```
+
+### Bundle Configuration
+In `tauri.conf.json`:
+```json
+{
+  "bundle": {
+    "resources": [
+      {
+        "src": "../../target/release/wifi-densepose-sensing-server",
+        "target": "bin/wifi-densepose-sensing-server"
+      }
+    ]
+  }
+}
+```
+
+## Consequences
+
+### Positive
+- **Single package distribution**: Users download one DMG/MSI/EXE
+- **Version alignment**: Server and UI always match
+- **Better UX**: No PATH configuration required
+- **Offline capable**: Works without network access to download server
+
+### Negative
+- **Larger bundle size**: ~10-15MB additional for server binary
+- **Build complexity**: Must build server before bundling desktop
+- **Platform-specific**: Need separate server binaries per platform
+
+### Neutral
+- CI/CD workflow updated to build server before desktop
+- GitHub Actions builds all platforms (macOS arm64/x64, Windows x64)
+
+## WebSocket Integration
+The Sensing page connects to the bundled server's WebSocket endpoint:
+- `ws://127.0.0.1:{ws_port}/ws/sensing` - Real-time CSI data stream
+- `ws://127.0.0.1:{ws_port}/ws/pose` - Pose estimation stream
+
+Message format:
+```typescript
+interface WsSensingUpdate {
+  type: string;
+  timestamp: number;
+  source: string;
+  tick: number;
+  nodes: WsNodeInfo[];
+  classification: { motion_level: string; presence: boolean; confidence: number };
+  vital_signs?: { breathing_rate_hz?: number; heart_rate_bpm?: number };
+}
+```
+
+## Security Considerations
+- Server binary signed with same certificate as desktop app
+- Communication over localhost only (127.0.0.1)
+- No external network access by default
+- Process spawned as child of desktop app (inherits permissions)

+
+## Context
+
+The RuView desktop application currently provides device discovery, firmware flashing, OTA updates, and real-time sensing visualization. However, users cannot train models or configure RuVector signal processing modules directly from the desktop app.
+
+The following crates exist in the workspace but are not exposed in the desktop UI:
+
+### Training Crate (`wifi-densepose-train`)
+- Dataset management (MM-Fi, Wi-Pose formats)
+- Model architectures (CSI encoder, pose decoder)
+- Training loops with metrics tracking
+- Checkpoint save/load
+- ruview_metrics integration
+
+### RuVector Crates (5 modules)
+1. **ruvector-mincut** - Graph-based person segmentation, DynamicPersonMatcher
+2. **ruvector-attn-mincut** - Attention-weighted antenna selection
+3. **ruvector-temporal-tensor** - Temporal CSI compression, breathing detection
+4. **ruvector-solver** - Sparse interpolation, triangulation
+5. **ruvector-attention** - Spatial attention, BVP extraction
+
+## Decision
+
+Add a new **"Training"** page to the desktop application with tabbed navigation:
+
+### Tab Structure
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│  Training & Models                                          │
+├──────────┬──────────┬──────────┬──────────┬────────────────┤
+│ Datasets │  Models  │ Training │ RuVector │    Metrics     │
+└──────────┴──────────┴──────────┴──────────┴────────────────┘
+```
+
+### Tab 1: Datasets
+- **Download** standard datasets (MM-Fi, Wi-Pose)
+- **Import** custom CSI recordings
+- **Preview** dataset samples (CSI heatmaps, labels)
+- **Split** into train/val/test sets
+- **Statistics** - sample counts, class distribution
+
+### Tab 2: Models
+- **Browse** available architectures:
+  - CSI Encoder (CNN, Transformer)
+  - Pose Decoder (LSTM, GRU)
+  - AETHER embedding network (ADR-024)
+  - MERIDIAN domain adaptor (ADR-027)
+- **Load** checkpoints from disk
+- **View** model summary (params, layers, memory)
+- **Export** to ONNX/TorchScript
+
+### Tab 3: Training
+- **Configure** training:
+  - Learning rate, batch size, epochs
+  - Optimizer (Adam, SGD, AdamW)
+  - Loss function selection
+  - Data augmentation toggles
+- **GPU Detection** - CUDA/Metal availability
+- **Start/Stop** training jobs
+- **Progress** - live loss curves, ETA
+- **Checkpointing** - auto-save best model
+
+### Tab 4: RuVector
+- **Module Configuration**:
+  - MinCut graph parameters
+  - Attention weights
+  - Temporal compression ratio
+  - Solver interpolation settings
+- **Live Testing** - apply to real-time CSI stream
+- **Comparison** - A/B test configurations
+- **Export** - save optimal config
+
+### Tab 5: Metrics
+- **Loss Curves** - training/validation over epochs
+- **Evaluation** - PCK, mAP, IoU scores
+- **Confusion Matrix** - per-joint accuracy
+- **Export** - CSV, JSON, TensorBoard format
+

+#[derive(Serialize, Clone)]
+pub struct TrainingProgress {
+    pub epoch: u32,
+    pub total_epochs: u32,
+    pub batch: u32,
+    pub total_batches: u32,
+    pub train_loss: f32,
+    pub val_loss: Option<f32>,
+    pub learning_rate: f32,
+    pub eta_secs: u64,
+    pub gpu_memory_mb: Option<u64>,
+}
+
+// Emit every batch
+app.emit("training:progress", progress)?;
+
+// Emit on completion
+app.emit("training:complete", result)?;
+```
+
+## Implementation Plan
+
+### Phase 1: Foundation (Week 1-2)
+1. Create `Training` page skeleton with tabs
+2. Implement `detect_gpu` command
+3. Add dataset listing/download commands
+4. Design TypeScript types for all entities
+
+### Phase 2: Dataset Management (Week 3)
+1. MM-Fi dataset downloader
+2. Wi-Pose dataset downloader
+3. Custom dataset import (CSV/NPZ)
+4. Dataset preview component
+
+### Phase 3: Model Management (Week 4)
+1. Model architecture browser
+2. Checkpoint loading
+3. Model summary display
+4. ONNX export
+
+### Phase 4: Training Loop (Week 5-6)
+1. Training configuration UI
+2. Background training thread
+3. Progress event emission
+4. Checkpoint auto-save
+5. Training history persistence
+
+### Phase 5: RuVector Integration (Week 7)
+1. RuVector config UI
+2. Live CSI testing
+3. A/B comparison mode
+4. Config export/import
+
+### Phase 6: Metrics & Polish (Week 8)
+1. Loss curve visualization (Chart.js/Recharts)
+2. Evaluation metrics display
+3. Export functionality
+4. Error handling & edge cases
+
+## Risks & Mitigations
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| No GPU available | Medium | High | CPU fallback with warning |
+| Large dataset downloads | High | Medium | Resume support, progress UI |
+| Training crashes | Medium | High | Checkpoint recovery, error reporting |
+| Memory exhaustion | Low | High | Batch size auto-tuning |
+| UI blocking | Medium | High | All training in background thread |
+
+## Success Criteria
+
+1. User can download MM-Fi dataset from UI
+2. User can start training with GPU detection
+3. Live progress updates without UI freeze
+4. Training can be paused/resumed
+5. RuVector config changes apply to live CSI
+6. Metrics display updates in real-time
+7. Models can be exported to ONNX
+
+## Alternatives Considered
+
+### 1. Separate Training App
+- **Rejected**: Fragments user experience, duplicates code
+
+### 2. Web-based Training Dashboard
+- **Rejected**: Requires server, no offline support
+
+### 3. CLI-only Training
+- **Rejected**: Poor UX for non-technical users
