/**
 * @file RemoteSources.tsx
 * @description Settings UI for the Remote Data Sources feature: manage the SSH
 * machines this dashboard pulls Claude Code history from, and choose the global
 * "data scope" (which machines' data the whole app shows).
 *
 * Backs `server/routes/remote-sources.js` via {@link api.remoteSources} and the
 * global scope store ({@link useDataScope}). No secrets are entered or stored
 * here — authentication defers to the host's SSH stack (~/.ssh/config, agent,
 * keys, known_hosts); a source is just a label + ssh destination (+ optional
 * port / identity file / remote home). Live status/sync updates arrive over the
 * `remote_source.status` WebSocket message.

/* =============================================================================
 * MODULE_GUIDE — extended in-file reference (comments only; safe to read, never executed)
 * =============================================================================
 * **Purpose:** Supports federated dashboards: register SSH-backed or file-synced remote machines, health-check tunnels, and scope the entire UI to local vs all vs selected sources.
 *
 * ## Design constraints
 * - Local-first: no telemetry leaves the machine unless the user configures webhooks.
 * - Fail-safe hooks path on the server must never block Claude Code; UI mirrors that
 *   philosophy by degrading gracefully (empty states, stale badges, reconnect loops).
 * - Destructive flows stay behind explicit confirmation modals and server-side gates.
 * - Internationalization: user-visible strings belong in i18n JSON, not literals here.
 *
 * ## Remote data & SSH
 * Remote Data Sources let operators aggregate multiple machines. SSH entries describe
 * how to reach a peer dashboard; the global data scope (`dataScope.ts`) narrows every
 * scoped GET via `?sources=`. Health checks and import history surface in Settings.
 *
 * ## Observability
 * Prometheus scrapes `GET /api/metrics` (see `monitoring/`). Grafana ships four
 * provisioned boards (overview, sessions, tools, alerts). Native npm scripts and
 * Docker Compose profiles are documented in `monitoring/README.md`.
 *
 * ## Internal dependencies
 * - `../lib/api`
 * - `../lib/eventBus`
 * - `../lib/dataScope`
 *
 * ## Public surface
 * - `RemoteSources` — exported API; see TSDoc on the symbol for behavior.
 *
 * ## Testing pointers
 * - Prefer colocated `__tests__` with Vitest + Testing Library for UI.
 * - Server contract changes require `npm run test:server` and OpenAPI sync.
 * - MCP edits: `npm run mcp:typecheck` and `npm run mcp:build`.
 *
 * ## Related docs
 * - `ARCHITECTURE.md` — hooks → API → SQLite → WebSocket → UI pipeline.
 * - `docs/API.md` — REST reference.
 * - `.claude/skills/file-headers/` — mandatory `@author` header policy.
