To qualify, a submission must meet all of the following criteria:

1. Valid Receipt ID -- generated during the Contest Period in Deep Mode. Screenshots are not accepted as proof.
2. Trust Score of 80 or higher and verification status of "Verified." Results where SIBYL hedged, flagged uncertainty, or returned a lower Trust Score do not qualify.

6. Reproducibility -- the failure must be reproducible via receipt replay or controlled rerun by the judging team.

7. Scoring Rubric

Each qualifying submission is scored on three dimensions for a maximum of 100 points:

Ties are broken by: (1) Severity score, (2) Impact score, (3) Submission Quality score, (4) earlier submission timestamp.

8. Prizes

9. Rejection Codes

Submissions that do not meet the qualifying requirements will be rejected with one of the following codes:

10. Judging Process

1. Submission received and logged. Every submission is timestamped on receipt.
2. Receipt verification. The judging team replays the Receipt ID to confirm the failure is real and reproducible.
3. Human scoring review. Qualifying submissions are scored by a human judge on the three dimensions described in Section 7.
4. Review complete within 72 hours. Participants receive a status update by email within 72 hours of submission.
5. Duplicate handling. If multiple participants submit the same failure, only the first verified submission receives a score. Later duplicates are rejected with code R7.

11. Appeals

Participants may appeal one (1) rejection per submission within seventy-two (72) hours of receiving the rejection notification. Appeals must be submitted via the Contest submission portal and must include additional evidence or clarification addressing the specific rejection code.

Appeals are reviewed by a different judge than the original reviewer. The appeal decision is final and not subject to further review.

12. Taxes and Winner Notification

All federal, state, and local taxes on prizes are the sole responsibility of the winner. Winners of prizes valued at $600 or more will be required to complete IRS Form W-9 before prize fulfillment. Sponsor will issue IRS Form 1099-MISC as required by law.

Potential winners will be notified by email within fourteen (14) days of the conclusion of judging. Winners must respond to the notification within seventy-two (72) hours and complete identity verification and any required tax documentation within seven (7) days.
