A concrete starting point
Return twice the signed polygon area for 3–256 integer vertices with coordinate magnitudes at most 1000000. Test reversed order and collinear vertices, treating self-crossing paths algebraically and rejecting malformed coordinates.
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.
