+### Mission: Rock-Solid Performance
+
+**The app MUST remain fast, responsive, and never hang** — even with many tabs open and many subagent windows active. This is a core design principle, not a nice-to-have. Every feature must be built with this constraint in mind:
+
+- **60fps terminal rendering** with batched writes and `requestAnimationFrame`
+- **Auto-trimming buffers** prevent memory bloat in long-running sessions
+- **Debounced state persistence** (500ms) avoids disk thrashing
+- **SSE batching** (16ms) reduces client-side event storms
+- **Lazy loading** of agent transcripts and historical data
+- **No blocking operations** in the main event loop
+
+When adding new features, always ask: "Will this maintain responsiveness with 20 sessions and 50 agent windows?"
+
+**Version**: 0.1390 (must match `package.json`)
