 - File watcher uses notify crate v6, watches parent directory (NonRecursive), emits `file-changed` Tauri events.
 - Settings use key-value `settings` table in SQLite (session.rs). Frontend: `settings-bridge.ts` adapter. v3 uses SettingsTab.svelte rendered in sidebar drawer panel (v2 SettingsDialog.svelte deleted in P10). SettingsTab has two sections: Global (single-column layout, split into Appearance [theme dropdown, UI font dropdown with sans-serif options + size stepper, Terminal font dropdown with monospace options + size stepper] and Defaults [shell, CWD] — all custom themed dropdowns, no native `<select>`, all persisted via settings-bridge with keys: theme, ui_font_family, ui_font_size, term_font_family, term_font_size, default_shell, default_cwd) and Group/Project CRUD.
 - Notifications use ephemeral toast system: `notifications.svelte.ts` store (max 5, 4s auto-dismiss), `ToastContainer.svelte` display. Agent dispatcher emits toasts on agent complete/error/crash.
-- StatusBar component shows active group name, project count, agent count, tokens, cost. Uses workspace store (v3 rewrite, no longer uses layout store).
+- StatusBar → Mission Control bar: running/idle/stalled agent counts (color-coded), total $/hr burn rate, "needs attention" dropdown priority queue (up to 5 cards sorted by urgency score, click-to-focus), total tokens + cost. Uses health.svelte.ts store (not workspace store for health signals).
+- health.svelte.ts store: per-project health tracking via ProjectTracker map. ActivityState = inactive|running|idle|stalled (15-min stall threshold). Burn rate from 5-min EMA costSnapshots. Context pressure = tokens/model limit. Attention scoring: stalled=100, error=90, ctx>90%=80, ctx>75%=40. 5-second tick timer for reactive updates. API: trackProject(), recordActivity(), recordToolDone(), recordTokenSnapshot(), getProjectHealth(), getAttentionQueue(), getHealthAggregates(). Wired from agent-dispatcher (tool_call/tool_result/cost events), ClaudeSession (trackProject on create/restore), workspace store (clearHealthTracking on group switch).
+- ProjectHeader shows status dot (green pulse=running, gray=idle, orange pulse=stalled, dim=inactive) + context pressure badge (>90% red, >75% orange, >50% yellow) + burn rate badge ($/hr). Health prop from ProjectBox via getProjectHealth().
+- session_metrics SQLite table: per-project historical session data (project_id, session_id, timestamps, peak_tokens, turn_count, tool_call_count, cost_usd, model, status, error_message). 100-row retention per project. Tauri commands: session_metric_save, session_metrics_load. Persisted on agent completion via agent-dispatcher.
 - Agent tree (AgentTree.svelte) uses SVG with recursive layout. Tree data built by `agent-tree.ts` utility from agent messages.
 - ctx integration opens `~/.claude-context/context.db` as SQLITE_OPEN_READ_ONLY — never writes. CtxDb uses Option<Connection> for graceful absence if DB doesn't exist.
 - SSH sessions spawn TerminalPane with shell=/usr/bin/ssh and args array. No SSH library needed — PTY handles it natively.

 ### Changed
 - AgentPane UI redesign: sans-serif root font (system-ui), tool calls paired with results in collapsible `<details>` groups, hook messages collapsed into compact labels, context window usage meter in status strip, cost bar made minimal (no background), session summary with translucent background, two-phase scroll anchoring, tool-aware output truncation (Bash 500/Read 50/Glob 20 lines), colors softened via `color-mix()`, responsive margins via container queries (AgentPane.svelte)
