A concrete starting point
Decode a seven-bit Hamming word under an explicit assumption of at most one flipped bit. Check intact words and every single-bit position, reject malformed or non-binary input and make no claim to detect multiple errors.
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.
