On coverage, METR says assessors should verify that unmonitored inference is actually non-agentic rather than assume it, because a misaligned agent that compromised infrastructure could route actions through unmonitored paths.
For evasion testing, METR asks for at least ~100k representative internal agent transcripts and ~100 of the most severe incidents, both to find misbehavior monitors missed and to spot attack opportunities agents passed up.
METR flags monitor-agent collusion as a growing concern and suggests honeypots for monitors and searching monitors' chains of thought for discussion of collusion.
The access requested is broad: codebase access comparable to the developer's own security researchers, inference and monitor logs to cross-reference, and the ability to insert realistic attack trajectories to see whether human reviewers escalate them.
