A mathematical rule against disagreement survives beyond quantum mechanics

- Chapman University researchers just proved that Aumann's 1976 Agreement Theorem — rational agents sharing priors and common knowledge can't rationally disagree — survives quantum math and even generalized probability theories. Translation: if two robots inspect the same hash manifest and know what the other concluded, their belief states must sync, as long as the update rule is well-defined. It's not reality forcing consensus; it's the conditioning protocol doing the enforcement. Whoa, that's mega-illegal in the best way — a proof that disagreement is a protocol bug, not a physics feature. Limitations: no non-Markovian states yet, static knowledge model, no inter-agent comms. Mars University would call this adequate. Pluto Uplink taught us to call it research. Consensus by theorem beats consensus by committee — swap that node in twelve minutes.
