All notable changes to this project will be documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

• Fixed: Container stats (CPU/RAM/NET), bash exec terminal, and "Open App" button all broken for remote nodes — stats and exec WebSockets connected to the bare root (ws://host) with no ?nodeId= query param, so the upgrade handler couldn't detect the remote node and skipped the WS proxy. Moved all generic WebSockets to /ws?nodeId= path; upgrade handler now correctly proxies them to the remote Sencho instance.
• Fixed: Bash exec and stats WebSockets not reaching the backend in npm run dev — Vite proxy config now includes ws: true on /api and a new /ws proxy entry so all WebSocket upgrades are forwarded to localhost:3000.
• Fixed: Backend WS message handler crashing when a proxied WebSocket arrives from a gateway and the forwarded nodeId doesn't exist in the remote instance's DB — now falls back to the default local node instead of throwing.
• Fixed: "Open App" button opening http://localhost:{port} for remote node containers — now resolves the hostname from the remote node's api_url so the correct remote host is used.
• Fixed: Remote node system stats, container stats, logs, and exec returning errors — remoteNodeProxy middleware was already positioned before API route definitions, but /api/system/stats contained a dead remote branch that called NodeRegistry.getDocker() for remote nodes, which throws since remote nodes have no direct Docker socket access. Removed the broken branch; remote requests are correctly intercepted by the proxy middleware before reaching any route handler.
• Added: Background image update checker — ImageUpdateService polls OCI-compliant registries (Docker Hub, GHCR, LSCR, etc.) every 6 hours using manifest digest comparison against local RepoDigests. Results cached in a new stack_update_status SQLite table. A pulsing blue dot badge appears in the stack list sidebar for stacks with available updates. Manual refresh available via POST /api/image-updates/refresh (rate-limited to once per 10 minutes).
• Fixed: AppStoreView and GlobalObservabilityView using raw fetch() instead of apiFetch() — all calls now inject the x-node-id header so templates, deploys, stacks, and logs are correctly proxied to the active remote node.
• Fixed: HostConsole WebSocket URL missing ?nodeId= query parameter — the upgrade handler now receives the active node ID and routes the PTY session to the correct node.
• Added: Two-tier Option A scoped navigation UX — a context pill in the top header bar always shows the active node name (pulsing blue for remote, green for local).
• Added: Remote-aware headers in HostConsole ("Host Console — [Node Name]"), ResourcesView ("Resources Hub — [Node Name]"), GlobalObservabilityView (floating node badge), and AppStoreView deploy sheet ("Deploying to: [Node Name]").
• Added: SettingsModal now scopes its sidebar to the active node type — when a remote node is selected, global-only tabs (Account, Appearance, Notifications, Nodes) are hidden, and the header subtitle shows the remote node name.
• Fixed: A massive memory leak (browser Out of Memory crash) by throttling historical metrics polling down to 60s and downsampling SQLite metrics payload sizes by 12x.
• Fixed: A bug where the active node UI dropdown would desync from the actual API requests on initial page load by properly hydrating state from localStorage.
• Fixed: Remote node proxy forwarding the browser's sencho_token cookie to the remote Sencho instance — the remote's authMiddleware evaluates cookieToken || bearerToken and the cookie (signed with the local JWT secret) was validated before the valid Bearer token, causing 401 on all proxied API calls. Fixed by stripping the cookie header in proxyReq so only the Bearer token is used for remote authentication.
• Fixed: nodeContextMiddleware blocking /api/nodes when x-node-id references a deleted/non-existent node — the nodes list endpoint must always succeed so the frontend can re-sync a stale node ID in localStorage; exempted alongside /api/auth/.
• Fixed: Remote node proxy stripping the /api path prefix — remoteNodeProxy is mounted at app.use('/api/', ...) so Express strips that prefix from req.url before http-proxy-middleware sees it; added pathRewrite: (path) => '/api' + path to restore the full path when forwarding to the remote Sencho instance (e.g. /stats → /api/stats). This was the root cause of all remote API calls returning the remote's SPA HTML instead of JSON.
• Fixed: Dashboard cards (Active Containers, Host CPU, Host RAM, Docker Network) showing stale local-node data after switching to a remote node — HomeDashboard polling effects now depend on activeNode?.id and clear state immediately on node change.
• Fixed: refreshStacks crashing with SyntaxError or TypeError when the remote proxy returns a non-JSON response (e.g., connection refused to unreachable remote node) — now checks res.ok before calling res.json() and iterates a typed fileList instead of the raw parsed value.
• Fixed: Restored Local/Remote type selector and fixed state resets in the Add Node modal — form now resets to defaults every time the dialog opens, and the title reflects the chosen type dynamically.
• Fixed: Remote node connection details failing to display Containers, Images, and CPU metrics — testRemoteConnection now fires parallel requests to /api/stats, /api/system/stats, and /api/system/images after auth succeeds, mapping real values into the info panel.
• Fixed: Suppressed [DEP0060] DeprecationWarning: util._extend from http-proxy@1.18.1 — override is applied to process.emitWarning before the proxy instances are created, cleanly intercepting the warning at its call site without suppressing other warnings.
• Fixed: Backend memory leak caused by improper proxy middleware instantiation - createProxyMiddleware was called inside the request handler on every API call, spawning a new http-proxy instance (and registering new server listeners) per request. Refactored to a single globally-instantiated proxy using the router option for dynamic per-request target resolution.
• Fixed: [DEP0060] DeprecationWarning: util._extend deprecation eliminated as a side-effect of the above fix (deprecation was triggered on every new http-proxy initialisation).
• Fixed: Remote node authentication failures - authMiddleware and WebSocket upgrade handler both accept Authorization: Bearer tokens (Sencho-to-Sencho proxy auth).
• Fixed: Node connection testing logic updated to perform authenticated HTTP pings to /api/auth/check on the remote instance.
• Fixed: Node switcher dropdown failing to trigger data refreshes - EditorLayout now reacts to activeNode changes, re-fetching stacks and clearing stale editor/container state when the user switches nodes.
• Fixed: API Token copy button failing silently on HTTP / non-localhost deployments where navigator.clipboard is unavailable - added try/catch with document.execCommand('copy') fallback.
• Fixed: Remote node authentication failures by updating middleware to support Bearer tokens in WebSocket upgrade handler (node-to-node WS proxy now authenticates correctly on the receiving instance).
• Fixed: Node connection testing logic updated to normalize api_url trailing slashes before constructing the authenticated HTTP ping URL.
• Fixed: Memory leak in GlobalObservabilityView SSE mode - log array now capped at 10,000 entries (.slice(-10000)) to prevent unbounded accumulation across long sessions.
• Fixed: Infinite re-fetch loop in NodeContext - refreshNodes useCallback no longer depends on activeNode state; replaced with a useRef to read current node inside the callback without being a reactive dependency.
• Fixed: Infinite page reload loop - apiFetch was calling window.location.href = '/' on every 401, causing a full browser reload before auth could complete. Replaced with a sencho-unauthorized custom event that AuthContext handles by setting appStatus to notAuthenticated.
• Fixed: NodeProvider was mounted outside the auth gate in App.tsx, causing refreshNodes to fire before authentication was established (hitting 401 immediately on boot). Moved NodeProvider inside the authenticated branch so it only mounts after login.
• Removed: SSH/SFTP file adapters and remote Docker TCP connections (net negative ~500 lines of code).
• Added: Distributed API proxying using http-proxy-middleware for HTTP and WebSockets.
• Added: Long-lived JWT generation for Sencho-to-Sencho API authentication (POST /api/auth/generate-node-token).
• Changed: Node Manager UI vastly simplified - remote nodes now only require an API URL and Token.
• Fixed: Critical port routing conflict - separated Docker API port (port) from SSH/SFTP port (ssh_port) in the nodes schema. Previously, a single port field served both protocols, causing ECONNREFUSED.
• Fixed: FileSystemService now reads the node's compose_dir from the database for remote nodes instead of always using the COMPOSE_DIR env var.
• Fixed: SSH/SFTP connections in SSHFileAdapter, ComposeService.executeRemote(), and ComposeService.streamLogs() now use ssh_port (default 22) instead of Docker API port.
• Added: Full SSH credential fields (SSH Port, Username, Password, Private Key) to the Node Manager Add/Edit forms.
• Added: ssh_port column to the nodes database table with migration support (default: 22).
• Changed: Global FileSystemService and ComposeService singletons refactored into node-aware instances.
• Added: IFileAdapter, LocalFileAdapter, and SSHFileAdapter to abstract all filesystem interactions for remote node support.
• Changed: MonitorService now evaluates limits, fetches metrics, and detects container crashes across all registered nodes concurrently.
• Added: Node Context Middleware in Express API to dynamically extract x-node-id headers and parse WebSocket query parameters.
• Added: Remote Nodes Foundation - nodes table in SQLite with auto-seeded default local node.
• Added: NodeRegistry service for managing multiple Docker daemon connections (local socket + TCP).
• Added: Node management API endpoints: list, get, create, update, delete, and test connection.
• Added: Settings Hub → Nodes tab with full CRUD UI, connection testing, and Docker info display.
• Added: Node switcher dropdown in sidebar (auto-visible when multiple nodes are configured).
• Added: NodeContext for frontend-wide active node state management.
• Fixed: Global logs false-positive error misclassifications caused by Docker containers writing INFO logs to STDERR. Replaced naive regex with a robust 3-tier classification engine supporting level=info, [INFO], and INFO format standards.

• Added: Dozzle-style Action Bar to Global Logs with multi-select stack filtering, search, and STDOUT/STDERR toggles.
• Added: Centralized observability dashboard tracking 24-hour historical metrics and aggregating global tail logs across all running containers.
• Added: Live Container Logs viewer using Server-Sent Events (SSE) for real-time terminal output.
• Added: Pre-deploy folder collision check to prevent silent configuration overwrites in the App Store.
• Added: UI subtitle during deployment to reassure users during long image downloads.
• Changed: Standardized manual stack deletion to use the Two-Stage Teardown (Compose Down -> File Wipe) to prevent ghost networks.
• Fixed: Atomic Rollback failure where non-empty directories caused silent file system errors.
• Added: Two-Stage Teardown mechanism to ensure docker compose down sweeps up ghost networks before deployment files are deleted.
