Note This score estimates the likelihood that code was AI-generated. It is a screening signal, not proof of AI use. False positives and false negatives occur. Always review flagged work with the author and follow your institution’s or company’s policies before taking any action.

Why these segments were flagged

overall

Too short and too close to the course starter template for a useful signal. The report declines to score this file — review it by hand if it matters.

Signal groups referenced: naming patterns · comment density · structural predictability · edge-case handling.

Sheet 4 · How to use this report + archival record

how to use this reportpage 4 / 4

How to use this report

This report is a record of a screening step. It is not a finding of misconduct, and it is not a basis for a grade penalty or a hiring decision on its own.

Ask the author to explain the flagged snippets — people who wrote the code can usually walk through it.
Ask them to extend or modify the flagged code on the spot, with a small change in requirements.
Compare with the author's earlier work before drawing any conclusion.
