Finding 1 (the real crash): Selection::clear() drops rows and anchor, called from TranscriptScreen::apply's Rebuild arm right before List::clear() -- push_row re-registers survivors as it rebuilds each row. Fixes a WeakWidget outliving the row group_tool_runs regrouped away, which panicked the next long-press anywhere. New apply_tests test builds a real TranscriptScreen, forces the regroup, and confirms no panic. Findings 2-5: debug_assert!s on List::place's slot, List::fling and FlingCalculator's velocity finiteness, VelocityTracker::add_sample's chronological order, and FrameReport::mark_phase's non-decreasing start_index. Finding 7: bench_client.rs's battery_line guard restructured so the empty check can't be separated from its unwraps by a future edit. Findings 9/10: new List tests pinning tick_fling's per-tick deceleration and replace_back's evicted-key cleanup with a different key than the existing tests use. IRIS.md's replace_back/clear/apply entry gained the side-table-clearing note the Docs finding asked for. Also records this pass's DragGesture-merge verification in RUST.md (tap stays vs swipe doesn't, a real fling keeps moving after release, keyboard cycles confirmed via on_insets_changed) and annotates the two IRIS_TODO.md phone-report items it targets.
