-
----
-
-## 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())
-        // ...
-    })
