A concrete starting point
Interleave two nonnegative integer grid coordinates into a Morton index with a declared bit width. Check corner coordinates and the maximum supported width, rejecting negatives, fractions and coordinates that do not fit.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
