Cache semantic timeline anchors and disclosures per session instead of relying on KeepAlive. Restore state after virtualized layout stabilization while preserving explicit focus and tail-follow behavior.
Render SessionDetail through measured dynamic-height virtual rows while preserving disclosure state, UUID navigation, reader anchoring, and tail-follow across live updates.
Add focused state/reconciliation tests plus a production Electron harness covering long-session DOM bounds, scrolling performance, offscreen navigation, and live viewport stability.
