+# 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 |
+|--------|---------|---------|--------|----------|----------|
+| **Settings** | `get_settings` | ✅ Done | ✅ Done | P0 | File permissions |
+| | `save_settings` | ✅ Done | ✅ Done | P0 | Input validation |
+| **Discovery** | `discover_nodes` | Stub | Full mDNS + UDP | P1 | Network boundary |

+| | `batch_ota_update` | Stub | Parallel with backoff | P2 | Rate limiting |
+| **WASM** | `wasm_list` | Stub | HTTP GET /api/wasm | P2 | Response validation |
+| | `wasm_upload` | Stub | HTTP POST multipart | P2 | Size limits, signing |
+| | `wasm_control` | Stub | HTTP POST commands | P2 | Action whitelist |
+| **Server** | `start_server` | Partial | Child process spawn | P1 | Port validation |
+| | `stop_server` | Partial | Graceful shutdown | P1 | PID verification |
+| | `server_status` | Partial | Health check | P1 | Timeout handling |

+
+## 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());

+
+        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"] }

+# 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)
