+## Session 9: Optimize list-table-v2 resize performance
+
+**Date**: 2026-03-31
+**Task**: Optimize list-table-v2 resize performance
+
+### Summary
+
+Implemented 3-layer performance optimization for list-table-v2: (1) Height-change detection - only re-probe when mini-table height actually changes, (2) Viewport-based observer detachment - ResizeObserver only attached when table is visible, (3) Display:none for off-screen tables - removes hidden mini-tables from GPU layout. Also added oxlint as linter.
