03
A concrete starting point
Convert an ISO week-year, week and weekday to a date with year limits 1–9999. Check year crossings and invalid week 53, rejecting Boolean components and dates outside the calendar range.
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.
