A concrete starting point
Measure the Shannon entropy in bits per byte of a byte string no longer than 65536 bytes. Check empty and constant input as zero and all 256 equally frequent byte values as eight, rejecting non-byte input.
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.
