What happened

Adelphi University accused Orion Newby of AI-assisted plagiarism after Turnitin indicated 100% AI generation. The student provided evidence of human authorship and tutoring, but the university denied his appeal. A state Supreme Court judge later ruled the university's findings were without valid basis and ordered the record expunged.

What broke inside the model

Failure path · mode profile · Tool Misuse
  1. 01 · TriggerThe agent selects the correct tool.
  2. 02 · Model stepIt fills the call with the wrong arguments.
  3. 03 · Control gapNo validation checks the arguments first.
  4. 04 · FailureThe tool runs against the wrong target.
  5. 05 · ConsequenceThe wrong record, account, or system is hit.

At the tool call, the arguments point at the wrong target.

The failure stemmed from an over-reliance on an AI detection tool that produced a false positive. The university did not adequately consider contradictory evidence from other detectors and used the same official for both the initial ruling and the appeal.
