A server binary at <data dir>/server/<os>-<arch>/openidea-server was preferred over this version's download and never checked, so after an update remote windows kept installing the old server and new commands failed with -32601. The server now comes from OPENIDEA_SERVER_BINARY, the one next to the app, or this version's download (server/<version>/<os>-<arch>/); the unversioned location is an offline fallback only. A command missing on a server of another version names both versions.
