QA targets for the newest UX reports (pending until their owners land): s37 browser chevrons on every node kind (all toggle; no Joints folder yet), s38 view animations to Top/Bottom end without a jump (the last frame turns 22.5 degrees today), s39 view cube edge/corner hover lights 2/3 patches, s40 toolbar Pin/Remove/reorder survive a restart and the workspace switcher spans the toolbar; ui_layout tests: every command dialog docked right at 260-380 px (or 480-560 for tables; the exploded view is 635), other windows fit on screen. Harness: published rects and counts, browser rows/fold arrows as handles, camera and view_anim steps, ui.at cube points, settings carried over a close restart, an adhoc scenario runner
