Case contract

Move selected columns as a schema-ordered block relative to a visible nonmoving target, preserve hidden columns, reject any locked or pane-incompatible member, and compute insertion after removing the whole source block.

Why this case matters

An offline table UI model isolates table column drag transaction, including adversarial row/column relationships.

One recorded failure
