+# Charon Copilot Instructions
+
+## 🚨 CRITICAL ARCHITECTURE RULES 🚨
+- **Single Frontend Source**: All frontend code MUST reside in `frontend/`. NEVER create `backend/frontend/` or any other nested frontend directory.
+- **Single Backend Source**: All backend code MUST reside in `backend/`.
+- **No Python**: This is a Go (Backend) + React/TypeScript (Frontend) project. Do not introduce Python scripts or requirements.
+
+## Big Picture
+- `backend/cmd/api` loads config, opens SQLite, then hands off to `internal/server` where routes from `internal/api/routes` are registered.
+- `internal/config` respects `CHARON_ENV`, `CHARON_HTTP_PORT`, `CHARON_DB_PATH`, `CHARON_FRONTEND_DIR` (CHARON_ preferred; CPM_ still supported) and creates the `data/` directory; lean on these instead of hard-coded paths.
+- All HTTP endpoints live under `/api/v1/*`; keep new handlers inside `internal/api/handlers` and register them via `routes.Register` so `db.AutoMigrate` runs for their models.
+- `internal/server` also mounts the built React app (via `attachFrontend`) whenever `frontend/dist` exists, falling back to JSON `{"error": ...}` for any `/api/*` misses.
+- Persistent types live in `internal/models`; GORM auto-migrates them each boot, so evolve schemas there before touching handlers or the frontend.
+
+## Backend Workflow
+- Run locally with `cd backend && go run ./cmd/api`; run tests with `go test ./...` (see `proxy_host_handler_test.go` for the in-memory SQLite/Gin harness pattern).
+- Handlers return structured errors using `gin.H{"error": "message"}` and standard HTTP codes—mirror the `ProxyHostHandler` lifecycle for new CRUD endpoints.
+- UUIDs (`github.com/google/uuid`) are generated server-side and exposed as `uuid` fields; clients never send numeric IDs.
+- Query lists sorted by `updated_at desc` (see `.Order("updated_at desc")` in `List`); match that ordering for user-visible collections.
+- Long-running work must respect the graceful shutdown flow in `server.Run(ctx)`—avoid background goroutines that ignore the context.
+
+## Frontend Workflow
+- **Location**: Always work within `frontend/`.
+- **Stack**: React 18 + Vite + TypeScript + TanStack Query (React Query).
+- **State Management**: Use `src/hooks/use*.ts` wrapping React Query. Do not use raw `useEffect` for data fetching.
+- **API Layer**: Create typed API clients in `src/api/*.ts` that wrap `client.ts`.
+- **Development**: Run `cd frontend && npm run dev`. Vite proxies `/api` to `http://localhost:8080`.
+- **Components**: Screens live in `src/pages`. Reusable UI in `src/components`.
+- **Forms**: Use local `useState` for form fields, submit via `useMutation` from custom hooks, then `invalidateQueries` on success.
+
+## Cross-Cutting Notes
+- Run the backend before the frontend; React Query expects the exact JSON produced by GORM tags (snake_case), so keep API and UI field names aligned.
+- When adding models, update both `internal/models` and the `AutoMigrate` call inside `internal/api/routes/routes.go`; register new Gin routes right after migrations for clarity.
+- Tests belong beside handlers (`*_test.go`); reuse the `setupTestRouter` helper structure (in-memory SQLite, Gin router, httptest requests) for fast feedback.
+- **Testing Requirement**: All new code (features, bug fixes, refactors) MUST include accompanying unit tests. Ensure tests cover happy paths and error conditions.
+- **Ignore Files**: When creating new file types, directories, or build artifacts, ALWAYS check and update `.gitignore`, `.dockerignore`, and `.codecov.yml` to ensure they are properly excluded or included as required.
+- The root `Dockerfile` builds the Go binary and the React static assets (multi-stage build).
+- Branch from `feature/**` and target `development`.
+
+## Documentation
+- **Feature Documentation**: When adding new features, update `docs/features.md` to include the new capability. This is the canonical list of all features shown to users.
+- **README**: The main `README.md` is a marketing/welcome page. Keep it brief with top features, quick start, and links to docs. All detailed documentation belongs in `docs/`.
+- **Link Format**: Use GitHub Pages URLs for documentation links, not relative paths:
+  - Docs: `https://wikid82.github.io/charon/` (index) or `https://wikid82.github.io/charon/features` (specific page, no `.md`)
+  - Repo files (CONTRIBUTING, LICENSE): `https://github.com/Wikid82/charon/blob/main/CONTRIBUTING.md`
+  - Issues/Discussions: `https://github.com/Wikid82/charon/issues` or `https://github.com/Wikid82/charon/discussions`
+
+## CI/CD & Commit Conventions
+- **Docker Builds**: The `docker-publish` workflow skips builds for commits starting with `chore:`.
+- **Triggering Builds**: To ensure a new Docker image is built (e.g., for testing on VPS), use `feat:`, `fix:`, or `perf:` prefixes.
+- **Beta Branch**: The `feature/beta-release` branch is configured to ALWAYS build, overriding the skip logic.

+
+This project follows a Code of Conduct that all contributors are expected to adhere to:
+
+- Be respectful and inclusive
+- Welcome newcomers and help them get started
+- Focus on what's best for the community
+- Show empathy towards other community members
+
+## Getting Started
+
+-### Prerequisites
+
+- **Go 1.24+** for backend development
+- **Node.js 20+** and npm for frontend development
+- Git for version control
+- A GitHub account
+
+### Fork and Clone
+
+1. Fork the repository on GitHub
+2. Clone your fork locally:
+```bash
+git clone https://github.com/YOUR_USERNAME/charon.git
+cd charon
+```
+
+3. Add the upstream remote:
+```bash
+git remote add upstream https://github.com/Wikid82/charon.git
+```
+
+### Set Up Development Environment
+
+**Backend:**
+```bash
+cd backend
+go mod download
+go run ./cmd/seed/main.go  # Seed test data
+go run ./cmd/api/main.go   # Start backend
+```
+
+**Frontend:**
+```bash
+cd frontend
+npm install
+npm run dev  # Start frontend dev server
+```
+
+## Development Workflow
+
+### Branching Strategy
+
+- **main** - Production-ready code
+- **development** - Main development branch (default)
+- **feature/** - Feature branches (e.g., `feature/add-ssl-support`)
+- **bugfix/** - Bug fix branches (e.g., `bugfix/fix-import-crash`)

+
+### Keeping Your Fork Updated
+
+```bash
+git checkout development
+git fetch upstream
+git merge upstream/development
+git push origin development
+```
+
+## Coding Standards
+
+### Go Backend
+
+- Follow standard Go formatting (`gofmt`)
+- Use meaningful variable and function names
+- Write godoc comments for exported functions
+- Keep functions small and focused
+- Handle errors explicitly
+
+**Example:**
+```go
+// GetProxyHost retrieves a proxy host by UUID.
+// Returns an error if the host is not found.
+func GetProxyHost(uuid string) (*models.ProxyHost, error) {
+    var host models.ProxyHost
+    if err := db.First(&host, "uuid = ?", uuid).Error; err != nil {
+        return nil, fmt.Errorf("proxy host not found: %w", err)
+    }
+    return &host, nil
+}
+```
+
+### TypeScript Frontend
+
+- Use TypeScript for type safety
+- Follow React best practices and hooks patterns
+- Use functional components
+- Destructure props at function signature
+- Extract reusable logic into custom hooks
+
+**Example:**
+```typescript
+interface ProxyHostFormProps {
+  host?: ProxyHost
+  onSubmit: (data: ProxyHostData) => Promise<void>
+  onCancel: () => void
+}
+
+export function ProxyHostForm({ host, onSubmit, onCancel }: ProxyHostFormProps) {
+  const [domain, setDomain] = useState(host?.domain ?? '')
+  // ... component logic
+}
+```
+
+### CSS/Styling
+
+- Use TailwindCSS utility classes
+- Follow the dark theme color palette
+- Keep custom CSS minimal
+- Use semantic color names from the theme
+
+## Testing Guidelines
+
+### Backend Tests
+
+Write tests for all new functionality:
+
+```go
+func TestGetProxyHost(t *testing.T) {
+    // Setup
+    db := setupTestDB(t)
+    host := createTestHost(db)
+
+    // Execute
+    result, err := GetProxyHost(host.UUID)
+
+    // Assert
+    assert.NoError(t, err)
+    assert.Equal(t, host.Domain, result.Domain)
+}
+```
+
+**Run tests:**
+```bash
+go test ./... -v
+go test -cover ./...
+```
+
+### Frontend Tests
+
+Write component and hook tests using Vitest and React Testing Library:
+
+```typescript
+describe('ProxyHostForm', () => {
+  it('renders create form with empty fields', async () => {
+    render(
+      <ProxyHostForm onSubmit={vi.fn()} onCancel={vi.fn()} />
+    )
+
+    await waitFor(() => {
+      expect(screen.getByText('Add Proxy Host')).toBeInTheDocument()
+    })
+  })
+})
+```
+
+**Run tests:**
+```bash
+npm test              # Watch mode
+npm run test:coverage # Coverage report
+```
+
+### Test Coverage
+
+- Aim for 80%+ code coverage
+- All new features must include tests
+- Bug fixes should include regression tests

+# Docker Deployment Guide
+
+Charon is designed for Docker-first deployment, making it easy for home users to run Caddy without learning Caddyfile syntax.
+
+## Quick Start
+
+```bash
+# Clone the repository
+git clone https://github.com/Wikid82/charon.git
+cd charon
+
+# Start the stack
+docker-compose up -d
+
+# Access the UI
+open http://localhost:8080
+```
+
+## Architecture
+
+Charon runs as a **single container** that includes:
+1.  **Caddy Server**: The reverse proxy engine (ports 80/443).
+2.  **Charon Backend**: The Go API that manages Caddy via its API (binary: `charon`, `cpmp` symlink preserved).
+3.  **Charon Frontend**: The React web interface (port 8080).
+
+This unified architecture simplifies deployment, updates, and data management.
+
+```
+┌──────────────────────────────────────────┐
+│  Container (charon / cpmp)               │
+│                                          │
+│  ┌──────────┐   API    ┌──────────────┐  │
+│  │  Caddy   │◄──:2019──┤  Charon App  │  │
+│  │ (Proxy)  │          │  (Manager)   │  │
+│  └────┬─────┘          └──────┬───────┘  │
+│       │                       │          │
+└───────┼───────────────────────┼──────────┘
+        │ :80, :443             │ :8080
+        ▼                       ▼
+    Internet                 Web UI
+```
+
+## Configuration
+
+### Volumes
+
+Persist your data by mounting these volumes:
+
+| Host Path | Container Path | Description |
+|-----------|----------------|-------------|
+| `./data` | `/app/data` | **Critical**. Stores the SQLite database (default `charon.db`, `cpm.db` fallback) and application logs. |
+| `./caddy_data` | `/data` | **Critical**. Stores Caddy's SSL certificates and keys. |
+| `./caddy_config` | `/config` | Stores Caddy's autosave configuration. |
+
+### Environment Variables
+
+Configure the application via `docker-compose.yml`:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+ | `CHARON_ENV` | `production` | Set to `development` for verbose logging (`CPM_ENV` supported for backward compatibility). |
+ | `CHARON_HTTP_PORT` | `8080` | Port for the Web UI (`CPM_HTTP_PORT` supported for backward compatibility). |
+| `CHARON_DB_PATH` | `/app/data/charon.db` | Path to the SQLite database (`CPM_DB_PATH` supported for backward compatibility). |
+| `CHARON_CADDY_ADMIN_API` | `http://localhost:2019` | Internal URL for Caddy API (`CPM_CADDY_ADMIN_API` supported for backward compatibility). |
+
+## NAS Deployment Guides
+
+### Synology (Container Manager / Docker)
+
+1.  **Prepare Folders**: Create a folder `docker/charon` (or `docker/cpmp` for backward compatibility) and subfolders `data`, `caddy_data`, and `caddy_config`.
+2.  **Download Image**: Search for `ghcr.io/wikid82/charon` in the Registry and download the `latest` tag.
+3.  **Launch Container**:
+    *   **Network**: Use `Host` mode (recommended for Caddy to see real client IPs) OR bridge mode mapping ports `80:80`, `443:443`, and `8080:8080`.
+    *   **Volume Settings**:
+        *   `/docker/charon/data` -> `/app/data` (or `/docker/cpmp/data` -> `/app/data` for backward compatibility)
+        *   `/docker/charon/caddy_data` -> `/data` (or `/docker/cpmp/caddy_data` -> `/data` for backward compatibility)
+        *   `/docker/charon/caddy_config` -> `/config` (or `/docker/cpmp/caddy_config` -> `/config` for backward compatibility)
+    *   **Environment**: Add `CHARON_ENV=production` (or `CPM_ENV=production` for backward compatibility).
+4.  **Finish**: Start the container and access `http://YOUR_NAS_IP:8080`.
+
+### Unraid
+
+1.  **Community Apps**: (Coming Soon) Search for "charon".
+2.  **Manual Install**:
+    *   Click **Add Container**.
+    *   **Name**: Charon
+    *   **Repository**: `ghcr.io/wikid82/charon:latest`
+    *   **Network Type**: Bridge
+    *   **WebUI**: `http://[IP]:[PORT:8080]`
+    *   **Port mappings**:
+        *   Container Port: `80` -> Host Port: `80`
+        *   Container Port: `443` -> Host Port: `443`
+        *   Container Port: `8080` -> Host Port: `8080`
+    *   **Paths**:
+        *   `/mnt/user/appdata/charon/data` -> `/app/data` (or `/mnt/user/appdata/cpmp/data` -> `/app/data` for backward compatibility)
+        *   `/mnt/user/appdata/charon/caddy_data` -> `/data` (or `/mnt/user/appdata/cpmp/caddy_data` -> `/data` for backward compatibility)
+        *   `/mnt/user/appdata/charon/caddy_config` -> `/config` (or `/mnt/user/appdata/cpmp/caddy_config` -> `/config` for backward compatibility)
+3.  **Apply**: Click Done to pull and start.
+
+## Troubleshooting
+
+### App can't reach Caddy
+
+**Symptom**: "Caddy unreachable" errors in logs
+
+**Solution**: Since both run in the same container, this usually means Caddy failed to start. Check logs:
+```bash
+docker-compose logs app
+```
+
+### Certificates not working
+
+**Symptom**: HTTP works but HTTPS fails
+
+**Check**:
+1. Port 80/443 are accessible from the internet
+2. DNS points to your server
+3. Caddy logs: `docker-compose logs app | grep -i acme`
+
+### Config changes not applied
+
+**Symptom**: Changes in UI don't affect routing
+
+**Debug**:
+```bash
+# View current Caddy config
+curl http://localhost:2019/config/ | jq
+
+# Check Charon logs
+docker-compose logs app
+
+# Manual config reload
+curl -X POST http://localhost:8080/api/v1/caddy/reload
+```
+
+## Updating
+
+Pull the latest images and restart:
+
+```bash
+docker-compose pull
+docker-compose up -d
+```
+
+For specific versions:
+
+```bash
+# Edit docker-compose.yml to pin version
+image: ghcr.io/wikid82/charon:v1.0.0
+
+docker-compose up -d
+```
+
+## Building from Source
+
+```bash
+# Build multi-arch images
+docker buildx build --platform linux/amd64,linux/arm64 -t charon:local .
+
+# Or use Make
+make docker-build
+```
+
+## Security Considerations
+
+1. **Caddy admin API**: Keep port 2019 internal (not exposed in production compose)
+2. **Management UI**: Add authentication (Issue #7) before exposing to internet
+3. **Certificates**: Caddy stores private keys in `caddy_data` - protect this volume
+4. **Database**: SQLite file contains all config - backup regularly
+
+## Integration with Existing Caddy
+
+If you already have Caddy running, you can point Charon to it:
+
+```yaml
+environment:
+  - CPM_CADDY_ADMIN_API=http://your-caddy-host:2019
+```
+
+**Warning**: Charon will replace Caddy's entire configuration. Backup first!
+
+## Performance Tuning
+
+For high-traffic deployments:
+
+```yaml
+# docker-compose.yml
+services:
+  app:
+    deploy:
+      resources:
+        limits:
+          memory: 512M
+        reservations:
+          memory: 256M
+```
+
+## Next Steps
+
+- Configure your first proxy host via UI
+- Enable automatic HTTPS (happens automatically)
+- Add authentication (Issue #7)
+- Integrate CrowdSec (Issue #15)

+# Versioning Guide
+
+## Semantic Versioning
+
+Charon follows [Semantic Versioning 2.0.0](https://semver.org/):
+
+- **MAJOR.MINOR.PATCH** (e.g., `1.2.3`)
+  - **MAJOR**: Incompatible API changes
+  - **MINOR**: New functionality (backward compatible)
+  - **PATCH**: Bug fixes (backward compatible)
+
+### Pre-release Identifiers
+- `alpha`: Early development, unstable
+- `beta`: Feature complete, testing phase
+- `rc` (release candidate): Final testing before release
+
+Example: `0.1.0-alpha`, `1.0.0-beta.1`, `2.0.0-rc.2`
+
+## Creating a Release
+
+### Automated Release Process
+
+1. **Update version** in `.version` file:
+   ```bash
+   echo "1.0.0" > .version
+   ```
+
+2. **Commit version bump**:
+   ```bash
+   git add .version
+   git commit -m "chore: bump version to 1.0.0"
+   ```
+
+3. **Create and push tag**:
+   ```bash
+   git tag -a v1.0.0 -m "Release v1.0.0"
+   git push origin v1.0.0
+   ```
+
+4. **GitHub Actions automatically**:
+   - Creates GitHub Release with changelog
+   - Builds multi-arch Docker images (amd64, arm64)
+   - Publishes to GitHub Container Registry with tags:
+     - `v1.0.0` (exact version)
+     - `1.0` (minor version)
+     - `1` (major version)
+     - `latest` (for non-prerelease on main branch)
+
+## Container Image Tags
+
+### Available Tags
+
+- **`latest`**: Latest stable release (main branch)
+- **`development`**: Latest development build (development branch)
+- **`v1.2.3`**: Specific version tag
+- **`1.2`**: Latest patch for minor version
+- **`1`**: Latest minor for major version
+- **`main-<sha>`**: Commit-specific build from main
+- **`development-<sha>`**: Commit-specific build from development
+
+### Usage Examples
+
+```bash
+# Use latest stable release
+docker pull ghcr.io/wikid82/charon:latest
+
+# Use specific version
+docker pull ghcr.io/wikid82/charon:v1.0.0
+
+# Use development builds
+docker pull ghcr.io/wikid82/charon:development
+
+# Use specific commit
+docker pull ghcr.io/wikid82/charon:main-abc123
+```
+
+## Version Information
+
+### Runtime Version Endpoint
+
+```bash
+curl http://localhost:8080/api/v1/health
+```
+
+Response includes:
+```json
+{
+  "status": "ok",
+  "service": "charon",
+  "version": "1.0.0",
+  "git_commit": "abc1234567890def",
+  "build_date": "2025-11-17T12:34:56Z"
+}
+```
+
+### Container Image Labels
+
+View version metadata:
+```bash
+docker inspect ghcr.io/wikid82/charon:latest \
+  --format='{{json .Config.Labels}}' | jq
+```
+
+Returns OCI-compliant labels:
+- `org.opencontainers.image.version`
+- `org.opencontainers.image.created`
+- `org.opencontainers.image.revision`
+- `org.opencontainers.image.source`
+
+## Development Builds
+
+Local builds default to `version=dev`:
+```bash
+docker build -t charon:dev .
+```
+
+Build with custom version:
+```bash
+docker build \
+  --build-arg VERSION=1.2.3 \
+  --build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') \
+  --build-arg VCS_REF=$(git rev-parse HEAD) \
+  -t charon:1.2.3 .
+```
+
+## Changelog Generation
+
+The release workflow automatically generates changelogs from commit messages. Use conventional commit format:
+
+- `feat:` New features
+- `fix:` Bug fixes
+- `docs:` Documentation changes
+- `chore:` Maintenance tasks
+- `refactor:` Code refactoring
+- `test:` Test updates
+- `ci:` CI/CD changes
+
+Example:
+```bash
+git commit -m "feat: add TLS certificate management"
+git commit -m "fix: correct proxy timeout handling"
+```
+
+## CI Tag-based Releases (recommended)
+
+- CI derives the release `Version` from the Git tag (e.g., `v1.2.3`) and embeds this value into the backend binary via Go ldflags; frontend reads the version from the backend's API. This avoids automatic commits to `main`.
+- The `.version` file is optional. If present, use the `scripts/check-version-match-tag.sh` script or the included pre-commit hook to validate that `.version` matches the latest Git tag.
+- CI will still generate changelogs automatically using the release-drafter workflow and create GitHub Releases when tags are pushed.
