* fix(notifications): replace polling with Docker event stream for container lifecycle detection
Replaces the 30-second MonitorService crash-detection poll with a causal,
per-node Docker events stream. Eliminates false crash alerts on intentional
stops (docker stop, compose down, stack restart/update), detects OOM kills
as a distinct alert category, and surfaces real crashes in real time.
A new DockerEventManager spawns one DockerEventService per local node. Each
service consumes the filtered container event stream, classifies die events
against recent kill/oom state, and reconciles container state via snapshot
diffing on connect and reconnect. Rate limiting, exponential backoff with
jitter, and parse-error tolerance keep the stream resilient under load and
during daemon interruptions.
MonitorService retains host limits, janitor, version check, and stack metric
alerts; crash and healthcheck detection move out entirely.
* fix(tests): silence require-imports lint in hoisted mock factory
* feat(nodes): add capability-based node compatibility negotiation
Each Sencho instance now exposes /api/meta with its version and supported
capabilities. When the user switches nodes, the frontend fetches this
metadata and disables features the remote node doesn't support via a
CapabilityGate overlay. Version is shown in the node switcher dropdown
and connection test results.
- Backend: CapabilityRegistry with static capability list and fetchRemoteMeta helper
- Backend: /api/meta (public) and /api/nodes/:id/meta (auth) endpoints
- Frontend: NodeContext enhanced with per-node meta caching (5min TTL)
- Frontend: CapabilityGate component with typed Capability union
- Frontend: 13 features wrapped with capability gates
- Docs: node-compatibility.mdx + OpenAPI spec updates
* fix(nodes): revert to require() for package.json version reading
The static import fails in the Docker multi-stage build because the
root package.json is not copied into the backend-builder stage. The
require() call resolves at runtime when the file is available.
Install motion + animate-ui, overhaul design tokens with brand cyan accent,
and replace CSS keyframe animations in Dialog, Tabs, Switch, and Tooltip
with spring-physics and blur-fade transitions via animate-ui Radix primitives.
Add Node modal — type selector & state reset:
- Restored a Local/Remote <Select> dropdown in renderFormFields so users can
explicitly choose the node type instead of it defaulting silently to 'remote'.
- Switching type clears api_url and api_token so no stale remote credentials
carry over if a user switches from Remote to Local mid-form.
- Replaced the static "Add Remote Node" title with a dynamic one that reflects
the currently selected type ("Add Local Node" / "Add Remote Node").
- onOpenChange now resets formData to defaultFormData whenever the dialog
opens, preventing stale values from a previous session leaking in.
Remote connection details — real metrics:
- testRemoteConnection previously returned hard-coded '-' for containers,
images, and cpus after a successful auth/check ping.
- Now fires three parallel requests (Promise.allSettled) after auth passes:
/api/stats → containers total + running count
/api/system/stats → cpu.cores
/api/system/images → image list length
- Each field falls back to '-' gracefully if an endpoint is unavailable,
so a slow or older remote instance never breaks the connection test.
DEP0060 util._extend suppression:
- http-proxy@1.18.1 calls util._extend when createProxyServer() is first
invoked at runtime (NOT at import time). A process.emitWarning override
placed before the proxy instantiations intercepts only DEP0060 without
suppressing any other warnings. No package version changes needed.
Also includes linter/formatter normalisation across multiple files.
- Extend WS upgrade handler to accept Authorization: Bearer tokens as a
fallback to cookie auth. Remote Sencho instances receive proxied WS
connections carrying Bearer (no cookie), so the previous cookie-only
check caused immediate 401 rejections for all proxied log/terminal streams.
- Log token validation failures in authMiddleware (was silently swallowed,
violating no-empty-catch directive).
- Normalize api_url by stripping trailing slashes in testRemoteConnection,
the HTTP proxy target, and the WS proxy target to prevent double-slash URLs.
- NodeRegistry: wire TLS ca/cert/key into Dockerode when present on node config
- index.ts: /api/system/stats now branches on node type — remote nodes use docker.info() for CPU/RAM, local keeps systeminformation; disk gracefully returns null for remote
- index.ts: POST /api/nodes now persists tls_ca, tls_cert, tls_key fields
- FileSystemService: throw clean error on missing/empty compose_dir instead of crashing path.join
- FileSystemService: guard getStacks() against falsy item.name entries
- SSHFileAdapter: filter undefined/non-string names from SFTP readdir before returning
- NodeManager: add SSH Authentication Type toggle (Password vs Private Key)
- NodeManager: add Enable TLS toggle with conditional CA/cert/key textarea fields
- NodeManager: auto-test connection immediately after node creation
- NodeManager: replace "Strategy B" copy with Docker TCP setup instructions
- NodeManager: add pr-8 to header and DialogHeader to prevent overlap with parent dialog X button
