Case contract

Given positive row and column coordinates, independent anchor booleans and copy deltas, return translated [row,column]; resulting coordinates are positive.

Why this case matters

This isolated spreadsheet model makes cell semantics explicit; it does not claim compatibility with every workbook engine.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
