Advanced anti-cheat options

Optional per-plan defenses — all OFF by default. Enable only what your exam needs:

• Shuffle — randomizes question and option order per student, so neighbours get different sequences.
• Question pools — each student gets a random subset drawn from the paper's questions.
• Identity watermark — the student's ID is watermarked on the exam page to deter photographing or sharing.
• Integrity tags — blur/tab-switch and device signals appear as tags on the marking screen and the integrity report.
• Re-verification — flags the attempt when it opens on a different device than the one used to verify.
• Blur limit — auto-submits the attempt after N tab/page switches; 0 = disabled.
