mesh-sdk #150 (issue 1952) renamed health.Finding's Token to Ref, since the tool runner refuses state fields named like a credential, so the watchman no longer compiled against the latest mesh-sdk, which every module now builds against (ADR 0573 §2, issue 1585). The meaning is the same: the key's last part when it is not the kind. Claude-Session: https://claude.ai/code/session_01NcbgfJ9Gum47zkFKWRaovL
