+# JetKVM Copilot Instructions
+
+## Architecture Overview
+
+JetKVM is a high-performance KVM-over-IP solution with **bidirectional architecture**: a Go backend running on ARM hardware and a React/TypeScript frontend served by the device. The system provides real-time video streaming, HID input, virtual media mounting, and **2-way audio support** via WebRTC.
+
+### Core Components
+
+- **Backend**: Go application (`main.go`, `web.go`, `webrtc.go`) handling WebRTC, HTTP APIs, hardware interfaces
+- **Frontend**: React/TypeScript SPA (`ui/src/`) with Vite build system, served as embedded static files
+- **Hardware Layer**: CGO bridge (`internal/native/`) to ARM SoC for video capture, USB gadget, display control
+- **Audio System**: In-process CGO implementation (`internal/audio/`) with ALSA/Opus for USB Audio Gadget streaming
+- **USB Gadget**: Configurable emulation (`internal/usbgadget/`) - keyboard, mouse, mass storage, **audio device**
+
+## Development Workflows
+
+### Quick Development Commands
+```bash
+# Full development deployment (most common)
+./dev_deploy.sh -r <DEVICE_IP>
+
+# UI-only changes (faster iteration)
+cd ui && ./dev_device.sh <DEVICE_IP>
+
+# Backend-only changes (skip UI build)
+./dev_deploy.sh -r <DEVICE_IP> --skip-ui-build
+
+# Build for release
+make build_release
+```
+
+### Critical Build Dependencies
+- **Audio libraries**: `make build_audio_deps` builds ALSA and Opus static libs for ARM
+- **Native CGO**: `make build_native` compiles hardware interface layer
+- **Cross-compilation**: ARM7 with buildkit toolchain at `/opt/jetkvm-native-buildkit`
+
+### Testing
+```bash
+# Run Go tests on device
+./dev_deploy.sh -r <DEVICE_IP> --run-go-tests
+
+# UI linting
+cd ui && npm run lint
+```
+
+## Project-Specific Patterns
+
+### Configuration Management
+- **Single config file**: `/userdata/kvm_config.json` persisted across updates
+- **Config struct**: `config.go` with JSON tags, atomic operations for thread safety
+- **Migration pattern**: Use `ensureConfigLoaded()` before config access
+
+### WebRTC Architecture
+- **Session management**: `webrtc.go` handles peer connections with connection pooling
+- **Media tracks**: Separate video and **stereo audio tracks** in independent MediaStreams
+- **Data channels**: RPC (ordered), HID (unordered), upload, terminal, serial channels
+- **SDP munging**: Frontend modifies SDP for Opus stereo parameters (`OPUS_STEREO_PARAMS`)
+
+### Audio Implementation Details
+- **USB Audio Gadget**: UAC1 device presenting as stereo speakers + microphone
+- **Bidirectional streaming**: Output (device→browser) and input (browser→device) 
+- **CGO integration**: `internal/audio/cgo_source.go` bridges Go↔C for ALSA operations
+- **Frame-based processing**: 20ms Opus frames (960 samples @ 48kHz) for low latency
+
+### Frontend State Management
+- **Zustand stores**: `hooks/stores.ts` - RTC, UI, Settings, Video state with persistence
+- **JSON-RPC communication**: `useJsonRpc` hook for backend API calls
+- **Localization**: Paraglide.js with compile-time validation - all UI strings use `m.key()` pattern
+
+### USB Gadget Configuration
+- **Configfs-based**: Dynamic reconfiguration via `/sys/kernel/config/usb_gadget/`
+- **Transaction pattern**: `WithTransaction()` ensures atomic gadget changes
+- **Device composition**: Keyboard + mouse + mass storage + **audio** with individual toggle support
+
+## Integration Patterns
+
+### Backend API Structure
+- **JSON-RPC over WebSocket**: Primary communication via data channels
+- **HTTP endpoints**: `/api/*` for REST operations, `/static/*` for UI assets
+- **Configuration endpoints**: `rpc*` functions in `jsonrpc.go` with parameter validation
+
+### Cross-Component Communication
+- **Video pipeline**: `native.go` → WebRTC track → browser via H.264 streaming
+- **HID input**: Browser → WebRTC data channel → `internal/usbgadget/hid_*.go` → Linux gadget
+- **Audio pipeline**: ALSA capture → Opus encode → WebRTC → browser speakers (and reverse for mic)
+- **Virtual media**: HTTP upload → storage → NBD server → USB mass storage gadget
+
+### Error Handling Patterns
+- **Graceful degradation**: Audio/video failures don't crash core functionality
+- **Session isolation**: Per-connection logging with `connectionID` context
+- **Recovery mechanisms**: USB gadget timeouts, audio restart on device changes
+
+## Key Files for Common Tasks
+
+### Adding new RPC endpoints
+1. Add handler function in `jsonrpc.go` 
+2. Register in `rpcHandlers` map
+3. Add frontend hook in `useJsonRpc`
+
+### USB device modifications
+- `internal/usbgadget/config.go` - gadget composition and attributes
+- `internal/usbgadget/hid_*.go` - HID device implementations
+
+### Audio feature development
+- `audio.go` - high-level audio management and session integration
+- `internal/audio/` - CGO sources, relays, and C audio processing
+
+### Frontend feature development
+- `ui/src/routes/` - page components
+- `ui/src/components/` - reusable UI components  
+- `ui/localization/messages/en.json` - localizable strings
+
+---
+
+*This codebase uses advanced patterns like CGO, USB gadgets, and real-time media streaming. Focus on understanding the session lifecycle and cross-compilation requirements for effective development.*

+#### Using DevPod
+
+**For Apple Silicon (M1/M2/M3/M4) Mac users:** You must set the Docker platform to `linux/amd64` before starting the DevPod container, as the JetKVM build system requires x86_64 architecture:

+export DOCKER_DEFAULT_PLATFORM=linux/amd64
+devpod up . --id kvm --provider docker --devcontainer-path .devcontainer/docker/devcontainer.json
