03
A concrete starting point
Unmask up to 1048576 WebSocket payload bytes with a four-byte key. Check empty input and repeated key positions, rejecting other types or key lengths and verifying the double-mask round trip.
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.
