Flip Security (Trivy), Notifications (agents + history), and App Store from
global-and-hidden-on-remote to node-scoped so operators can manage them when a
remote node is selected in the node picker. The primary instance proxies the
calls to each remote, which resolves the correct per-instance binary state,
agent config, and template registry.
Backend: key `agents` and `notification_history` by `node_id` with idempotent
column-add migrations and a `(node_id, type)` unique index on agents, matching
the Labels pattern. Thread `req.nodeId` through the /api/agents and
/api/notifications routes. Internal NotificationService and ImageUpdateService
writes resolve the middleware default via `NodeRegistry.getDefaultNodeId()` so
monitor-emitted rows share a bucket with user-facing ones (avoids split-brain
where the UI sees test notifications but not internal alerts).
Frontend: split Security on remote to render only the scanner card and hide
scan policies and CVE suppressions (those remain control-plane-only). Drop the
misleading "Always Local" badge on Developer since retention windows govern
backend jobs, not UI state. Flip the App Store registry to node-scoped.
Docs: add a "What Settings apply per node" table to multi-node, clarify
remote alert setup in alerts-notifications, and note Trivy's per-host install
in vulnerability-scanning.
* docs: remove security-sensitive implementation details from public documentation
Generalize or remove internal architecture details that could aid targeted
attacks — CVE tables, database schema, rate limit thresholds, proxy internals,
encryption algorithm names, and WebSocket middleware bypass info.
* test(metrics): fix flaky minute-bucket aggregation test
Floor baseTime to the start of the current minute so baseTime + 5000
never crosses a minute boundary and produces 2 buckets instead of 1.
