The sidebar's scroll thumb sat there permanently once the task list overflowed. Keep the thumb transparent by default and paint it only while the pointer is over the sidebar. The track keeps its width in both states, so revealing it never reflows the list.

Captures what it took to see the sidebar hover change working: launch against a throwaway user-data dir so the developer's real data and any sibling worktree's dev instance stay out of the way, rebuild native modules when bun install lands the wrong arch, seed the sqlite db to reach list states, and drive the renderer over CDP — whose synthetic mouse is the only thing that makes :hover fire for a screenshot.

The track keeps its width in both states, so revealing it never reflows the list. No transition — Chromium doesn't reliably animate
::-webkit-scrollbar-thumb, so a fade there would be dead code.Also adds
.claude/skills/run-desktop— the launch-and-drive procedure this change was verified with, so the next UI change doesn't rediscover it: isolated--user-data-dir(keeps the real app data and any sibling worktree's dev instance out of the blast radius), an arch check that rebuilds native modules whenbun installlands the wrongbetter-sqlite3prebuild, a db seeder for list states, and a CDP driver whose synthetic mouse is the only thing that makes:hoverfire for a screenshot.Verified in the running app with 45 seeded tasks (sidebar scrollHeight 1264 vs clientHeight 900): thumb computes to
rgba(0,0,0,0)at rest andrgb(47,47,55)on hover, confirmed in cropped screenshots.
