📝 WalkthroughWalkthroughSidebar row lifting now supports organizable workspace rows as well as reorderable machines. Lifted organization drops map displayed slots to eligible siblings in the same pin tier. When a lifted drop is accepted, the lift finishes around the organization action. Machine detail tabs animate selection and count changes, with selection animation disabled when Reduce Motion is enabled. ChangesWorkspace Row Lifting

the real workspace row follows the pointer and its pin-tier siblings slide aside, open workspaces close for the drag and reopen after, and the drop commits the slot the rows show. leaving the tree puts the rows back and gives the drag its image again, so a workspace still drops onto a pane.
a lifted drop skips the pane ownership check (it only reorders), the drag image is only blanked once the row lifts and comes back if the tree reloads mid-drag, and the snapshot keeps its size.

…itself the lift matched rows by object identity, and the tree can hold different objects for the same workspace, so the drag never lifted. the hand-off picture now comes from the row view instead of the drag frame. debug logs say why a lift was skipped.

…ve it Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Closing open rows for a machine or workspace drag moved the held row's slot up by the height that closed above it, and the lift glided the row into that slot, leaving it that far above the pointer. The bottom row drifted most. The lift now scrolls the list so the slot stays where the row stood, carries any remainder as one shift on every row, and anchors the reopen at the end on the landed row, so the row stays under the hand and a cancel restores the original scroll. The held row's own folder closes again so every peer is one row. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A fixed shift on every row left rows at one end of a long list out of reach and showed blank bands while autoscrolling, since rows without views never draw. The container now lends the scroll view extra inset range for the drag, the real scroll does all of the anchoring, and the range goes back at the drop, cancel, or discard. Hover stays on the held row while begin lays out, and a list with nothing to scroll rests at its top after a drop. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The Cloud tree's scroll view adjusts its insets automatically, so AppKit recomputed them on its next layout and dropped the borrowed range mid-drag. The container now lends on top of the insets in effect, turns automatic adjustment off for the loan, and restores both when the range comes back. Resting insets are unchanged.

The determinism guard rejects sleep-then-assert. The drift the sleep waited out was the row gliding into a slot above the hand, so the tests now check that the slot itself stays where the hand pressed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Rows closing above the held machine now scroll the outline so its slot stays under the hand, so an unmoved hand is a window point, not the press's document coordinate. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Cloud workspaces in the sidebar now reorder the same way machines do: the real row follows the pointer, pin-tier siblings slide aside, and open rows close during the drag and reopen after the drop.
