-The overview loads the most important memories first (default 2,000 nodes). Completeness comes from exploration, not loading the entire corpus at once.
+The overview loads a bounded slice of the store — 2,000 nodes by default. That ceiling is now a **client-side** limit rather than a server one: the API's old `min(limit, 2000)` cap was lifted, and 2,000 is where the on-main-thread physics simulation (d3-force-3d + React Three Fiber) starts to stutter. There is no UI for it, but you can raise it for testing on capable hardware with `?cap=10000` in the URL or `localStorage.automem_snapshot_cap = '10000'`. Completeness comes from exploration, not loading the entire corpus at once.
