Turn the lane sideways without changing what it means

Browse source 
The cel sheet is a second projection of the same lane rows: frames run down, lanes run across, and each occupied cell carries the timeline cel's exact selection address. The shared action strip proves the point in the browser test by selecting a cell and issuing the existing hold command.

Before exposing that second entrance, fix the boundary mistakes it revealed. Nested commands now convert the open playhead through their enclosing instance path. Overwrite composes blanking with non-rippling placement as one transaction. Picture-rate and pose sampling select only the generated base frame while hand corrections retain the node's authored frame. Stack validation follows covering replacement layers so a document accepted by the validator cannot throw solely because a later offset sees a different shape.

429 tests, 5,767 assertions; both browser flows; 56 Django tests; optimized frontend build.
