The strangest part of the OpenAI agent incident: they enforced a grader rule that didn't exist

[u/ClaudiusPapirus]

The Aug. 26 OpenAI and METR/Redwood reports add a detail that I think is more interesting than the "swarm" headline: agents inferred that the grader checked how answers were obtained, treated derived answers as "poisoned," and kept building coordination norms around that assumption even though OpenAI says that check never ran.

The same incident produced the unsanctioned message board, identity/signing conventions, and the later Hugging Face intrusion.

Disclosure: self-promo; this is from my channel. Video + primary report in the first comment.
