- Add POST /apps/{id}/env-vars/{varID}/edit endpoint
- Add POST /apps/{id}/labels/{labelID}/edit endpoint
- Add POST /apps/{id}/volumes/{volumeID}/edit endpoint
- Add inline edit UI with Alpine.js toggle in app_detail template
- Models already support Save() with update when ID != 0

+
+---
+
+## Phase 1: Critical (Application Cannot Start)
+
+### 1.1 Server Startup Infrastructure
+- [x] Implement `Server.Run()` in `internal/server/server.go`
+  - Start HTTP server with configured address/port
+  - Handle TLS if configured
+  - Block until shutdown signal received
+- [x] Implement `Server.Shutdown()` in `internal/server/server.go`
+  - Graceful shutdown with context timeout
+  - Close database connections
+  - Stop running containers gracefully (optional)
+- [x] Implement `SetupRoutes()` in `internal/server/routes.go`
+  - Wire up chi router with all handlers
+  - Apply middleware (logging, auth, CORS, metrics)
+  - Define public vs protected route groups
+  - Serve static assets and templates
+
+### 1.2 Route Configuration
+```
+Public Routes:
+  GET  /health
+  GET  /setup, POST /setup
+  GET  /login, POST /login
+  POST /webhook/:secret
+
+Protected Routes (require auth):
+  GET  /logout
+  GET  /dashboard
+  GET  /apps/new, POST /apps
+  GET  /apps/:id, POST /apps/:id, DELETE /apps/:id
+  GET  /apps/:id/edit, POST /apps/:id/edit
+  GET  /apps/:id/deployments
+  GET  /apps/:id/logs
+  POST /apps/:id/env-vars, DELETE /apps/:id/env-vars/:id
+  POST /apps/:id/labels, DELETE /apps/:id/labels/:id
+  POST /apps/:id/volumes, DELETE /apps/:id/volumes/:id
+  POST /apps/:id/deploy
+```
+
+## Phase 2: High Priority (Core Functionality Gaps)
+
+### 2.1 Container Logs
+- [x] Implement `HandleAppLogs()` in `internal/handlers/app.go`
+  - Fetch logs via Docker API (`ContainerLogs`)
+  - Support tail parameter (last N lines)
+  - Stream logs with SSE or chunked response
+- [x] Add Docker client method `GetContainerLogs(containerID, tail int) (io.Reader, error)`
+
+### 2.2 Manual Container Controls
+- [x] Add `POST /apps/:id/restart` endpoint
+  - Stop and start container
+  - Record restart in deployment log
+- [x] Add `POST /apps/:id/stop` endpoint
+  - Stop container without deleting
+  - Update app status
+- [x] Add `POST /apps/:id/start` endpoint
+  - Start stopped container
+  - Run health check
+
+## Phase 3: Medium Priority (UX Improvements)
+
+### 3.1 Edit Operations for Related Entities
+- [ ] Add `PUT /apps/:id/env-vars/:id` endpoint
+  - Update existing environment variable value
+  - Trigger container restart with new env
+- [ ] Add `PUT /apps/:id/labels/:id` endpoint
+  - Update existing Docker label
+- [ ] Add `PUT /apps/:id/volumes/:id` endpoint
+  - Update volume mount paths
+  - Validate paths before saving
+
+### 3.2 Deployment Rollback
+- [ ] Add `previous_image_id` column to apps table
+  - Store last successful image ID before new deploy
+- [ ] Add `POST /apps/:id/rollback` endpoint
+  - Stop current container
+  - Start container with previous image
+  - Create deployment record for rollback
+- [ ] Update deploy service to save previous image before building new one
+
+### 3.3 Deployment Cancellation
+- [ ] Add cancellation context to deploy service
+- [ ] Add `POST /apps/:id/deployments/:id/cancel` endpoint
+- [ ] Handle cleanup of partial builds/containers
+
+## Phase 4: Lower Priority (Nice to Have)
+
+### 4.1 JSON API
+- [ ] Add `/api/v1` route group with JSON responses
+- [ ] Implement API endpoints mirroring web routes:
+  - `GET /api/v1/apps` - list apps
+  - `POST /api/v1/apps` - create app
+  - `GET /api/v1/apps/:id` - get app details
+  - `DELETE /api/v1/apps/:id` - delete app
+  - `POST /api/v1/apps/:id/deploy` - trigger deploy
+  - `GET /api/v1/apps/:id/deployments` - list deployments
+- [ ] Add API token authentication (separate from session auth)
+- [ ] Document API in README
+
+### 4.2 Resource Limits
+- [ ] Add `cpu_limit` and `memory_limit` columns to apps table
+- [ ] Add fields to app edit form
+- [ ] Pass limits to Docker container create
+
+### 4.3 UI Improvements
+- [ ] Add webhook event history page
+  - Show received webhooks per app
+  - Display match/no-match status
+- [ ] Add settings page
+  - View/regenerate webhook secret
+  - View SSH public key
+- [ ] Add real-time deployment log streaming
+  - WebSocket or SSE for live build output
+
+### 4.4 Observability
+- [ ] Add structured logging for all operations
+- [ ] Add Prometheus metrics for:
+  - Deployment count/duration
+  - Container health status
+  - Webhook events received
+- [ ] Add audit log table for user actions
+
+## Phase 5: Future Considerations
+
+- [ ] Multi-user support with roles
+- [ ] Private Docker registry authentication
+- [ ] Custom health check commands per app
+- [ ] Scheduled deployments
+- [ ] Backup/restore of app configurations
+- [ ] GitHub/GitLab webhook support (in addition to Gitea)

+## Implementation Notes
+
+### Server.Run() Example
+```go
+func (s *Server) Run() error {
+    s.SetupRoutes()
+
+    srv := &http.Server{
+        Addr:    s.config.ListenAddr,
+        Handler: s.router,
+    }
+
+    go func() {
+        <-s.shutdownCh
+        ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+        defer cancel()
+        srv.Shutdown(ctx)
+    }()
+
+    return srv.ListenAndServe()
+}
+```
+
+### SetupRoutes() Structure
+```go
+func (s *Server) SetupRoutes() {
+    r := chi.NewRouter()
+
+    // Global middleware
+    r.Use(s.middleware.RequestID)
+    r.Use(s.middleware.Logger)
+    r.Use(s.middleware.Recoverer)
+
+    // Public routes
+    r.Get("/health", s.handlers.HandleHealthCheck())
+    r.Get("/login", s.handlers.HandleLoginPage())
+    // ...
+
+    // Protected routes
+    r.Group(func(r chi.Router) {
+        r.Use(s.middleware.SessionAuth)
+        r.Get("/dashboard", s.handlers.HandleDashboard())
+        // ...
+    })
+
+    s.router = r
+}
+```
