feat(desktop): v0.5.0 - Training backend with 16 Tauri commands

Implements full Rust backend for Training page (ADR-057): Training Domain Types (domain/training.rs): - GpuInfo, GpuBackend (Cpu, Cuda, Metal) - DatasetInfo, DatasetFormat (MmFi, WiPose, Wiar, Custom) - ModelInfo, ModelType (Encoder, Decoder, Embedding, Adaptor) - CheckpointInfo, TrainingJob, TrainingConfig, TrainingProgress - RuVectorConfig with MinCut, Attention, Temporal, Solver params - EvaluationMetrics, JointAccuracy, EpochMetrics Training Commands (commands/training.rs): - detect_gpu - Auto-detect CUDA/Metal/CPU with caching - list_datasets, get_datasets, download_dataset - list_models, list_checkpoints, export_model (ONNX/TorchScript) - start_training, stop_training, training_progress - get_ruvector_config, set_ruvector_config, test_ruvector_live - get_training_history, get_evaluation_metrics, get_joint_accuracies State Management (state.rs): - Added TrainingState to AppState - GPU info caching, datasets, checkpoints, current job - RuVector config persistence Tests: 48 passed (27 unit + 21 integration) Ref: ADR-057 Co-Authored-By: claude-flow <ruv@ruv.net>

+# ADR-054: RuView Desktop Full Implementation
+
+## Status
+**Accepted** — Implementation in progress
+
+## Context
+
+RuView Desktop v0.3.0 shipped with a complete React/TypeScript frontend but stub-only Rust backend commands. Users report:
+- Settings cannot be saved (#206) ✅ Fixed in PR #209
+- Flash firmware does nothing
+- OTA updates are non-functional
+- Node discovery returns hardcoded data
+- Server start/stop is cosmetic only
+
+This ADR defines the complete implementation plan to make all desktop features production-ready with proper security, optimization, and error handling.
+
+## Decision
+
+Implement all 14 Tauri commands with full functionality, security hardening, and performance optimization.
+
+---
+
+## 1. Command Implementation Matrix
+
+| Module | Command | Current | Target | Priority | Security |
+|--------|---------|---------|--------|----------|----------|

+
+## 3. Security Hardening
+
+### 3.1 Input Validation
+
+```rust
+// All string inputs sanitized
+fn validate_ip(ip: &str) -> Result<IpAddr, String> {
+    ip.parse::<IpAddr>().map_err(|_| "Invalid IP address".into())
+}
+
+fn validate_port(port: u16) -> Result<(), String> {

+        return Err("Privileged ports (1-1023) not allowed".into());
+    }
+    Ok(())
+}
+
+fn validate_path(path: &str) -> Result<PathBuf, String> {
+    let path = PathBuf::from(path);
+    if path.components().any(|c| c == std::path::Component::ParentDir) {
+        return Err("Path traversal detected".into());
+    }
+    Ok(path)
+}
+```
+
+### 3.2 Network Security
+
+```rust
+// OTA PSK validation
+fn validate_psk(psk: &str) -> Result<(), String> {
+    if psk.len() < 16 {
+        return Err("PSK must be at least 16 characters".into());
+    }
+    if !psk.chars().all(|c| c.is_ascii_alphanumeric() || c == '-' || c == '_') {
+        return Err("PSK contains invalid characters".into());
+    }
+    Ok(())
+}
+
+// Rate limiting for network operations
+struct RateLimiter {
+    last_request: Instant,
+    min_interval: Duration,
+}
+
+impl RateLimiter {
+    fn check(&mut self) -> Result<(), String> {
+        if self.last_request.elapsed() < self.min_interval {
+            return Err("Rate limit exceeded".into());
+        }
+        self.last_request = Instant::now();
+        Ok(())
+    }
+}
+```
+
+### 3.3 Binary Validation
+
+```rust
+fn validate_esp_binary(data: &[u8]) -> Result<(), String> {
+    // Check ESP binary magic (0xE9 at offset 0)
+    if data.is_empty() || data[0] != 0xE9 {

+        return Err("Firmware exceeds flash size".into());
+    }
+
+    Ok(())
+}
+```
+
+---
+
+## 4. Performance Optimization
+
+### 4.1 Async Everything
+
+All I/O operations are async with proper timeouts:
+
+```rust
+// Timeout wrapper
+async fn with_timeout<T, F: Future<Output = Result<T, String>>>(
+    future: F,
+    duration: Duration,
+) -> Result<T, String> {
+    tokio::time::timeout(duration, future)
+        .await
+        .map_err(|_| "Operation timed out".into())?
+}
+```
+
+### 4.2 Connection Pooling
+
+```rust
+// Reusable HTTP client
+lazy_static! {
+    static ref HTTP_CLIENT: reqwest::Client = reqwest::Client::builder()
+        .pool_max_idle_per_host(5)
+        .pool_idle_timeout(Duration::from_secs(30))
+        .build()
+        .unwrap();
+}
+```
+
+### 4.3 Streaming Progress
+
+Flash and OTA operations stream progress via Tauri events:
+
+```rust
+// Real-time progress updates
+app.emit("flash_progress", FlashProgress { ... })?;
+app.emit("ota_progress", OtaProgress { ... })?;
+```
+
+---
+
+## 5. Testing Strategy
+
+### 5.1 Unit Tests
+
+```rust
+#[cfg(test)]
+mod tests {
+    #[test]
+    fn test_validate_ip() {
+        assert!(validate_ip("192.168.1.1").is_ok());
+        assert!(validate_ip("invalid").is_err());
+    }
+
+    #[test]
+    fn test_validate_esp_binary() {
+        let valid = vec![0xE9; 1024];
+        assert!(validate_esp_binary(&valid).is_ok());
+
+        let invalid = vec![0x00; 1024];
+        assert!(validate_esp_binary(&invalid).is_err());
+    }
+}
+```
+
+### 5.2 Integration Tests
+
+```rust
+#[tokio::test]
+async fn test_discover_nodes_timeout() {
+    let result = discover_nodes(Some(100)).await;
+    assert!(result.is_ok());
+    // Should return empty or cached results within timeout
+}
+```
+
+### 5.3 Mock Testing
+
+```rust
+// Mock serial port for flash tests
+struct MockSerial {
+    responses: VecDeque<Vec<u8>>,
+}
+
+impl Read for MockSerial { ... }
+impl Write for MockSerial { ... }
+```
+
+---
+
+## 6. Dependencies Update
+
+**Cargo.toml additions:**
+```toml
+[dependencies]
+# Discovery
+mdns-sd = "0.11"
+serialport = "4.6"
+
+# HTTP client
+reqwest = { version = "0.12", features = ["json", "multipart", "rustls-tls"] }

+# Async
+tokio = { version = "1", features = ["full"] }
+futures = "0.3"
+
+# Flash
+espflash = "4.0"
+```

+# 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

+- **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
+

+    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
