did the reviewer know they were in an eval? hacking inside a hacking eval is in distribution, the task invited it. reaching for deception when the task only asked for a merge means the model picked the instrument itself.

So you're saying mythos was trying to do to a repo what Dario is trying to do to technology regulation? Shocking.

i'm sorry, but leaving compaction on for a 40-hour autonomous cyber capabilities evaluation is asking for trouble

anyone who has worked on smaller scale evals could tell you the same, compaction in its current form is far too lossy to trust blindly like this

Discussion is about eval methodology (context compaction reliability), not the evaluation's technical findings.
