 The Remote Hub guide and affected CLI, server-config, management-API, and dashboard references have eight sources: root English plus `fr`, `ko`, `zh-cn`, `zh-tw`, `ru`, `ja`, and `tr`. English is canonical; commands, defaults, endpoint auth, and warnings remain exact in translations. A release requires the remote-only focused/full gates, privacy scan, GUI/docs builds, protocol compatibility receipts, and the MAINTAINERS security review for the exact head.

+requesting hub state. It passes a usable token only when the current connection matches the
+status snapshot's `serverUrl`, `apiKeyId`, and `connectedAt`, and the token fingerprint matches
