- Replace virtua with @tanstack/react-virtual for chat history on all surfaces: bottom anchoring (anchorTo: end), key-stable prepend preservation, and native iOS touch/momentum deferral live in the core - Patch virtual-core to clamp the render range to real scroll bounds during transient adjustments - Rows render in normal flow inside a translated wrapper so sticky user headers keep working; measurement snapshots cached per session - Pre-write container height in scrollToFn so the browser cannot clamp anchor corrections to the stale height; hold the prepend anchor for up to 180 frames on mobile while fresh rows settle (cancelled by user input; desktop relies on core anchoring alone) - Adaptive row-size estimate from per-session measured averages; disable reveal fade-in for virtualized history rows - Mobile loads older history only through an explicit localized top button: no scroll-position trigger and no post-mount background prepend, so every insert happens from a resting state; a quiet-window hold defers any stray prepend commit while a touch gesture is active - Desktop/VS Code keep the seamless scroll-up trigger and progressive background prepend
