A concrete starting point
Generate a Collatz trajectory from a positive integer under explicit step and value caps. Test a start of one, a sequence reaching one and both caps being exceeded, raising an error rather than claiming every sequence terminates.
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.
