/*
    Critical path (deep): file transfer, search and sharing.

    Extends the file-explorer coverage in 030 with the transfer-oriented
    File Manager features that move real bytes in and out of the system:
    multipart upload, media download (round-trip verification), search,
    and the share-link lifecycle (create / list / public download /
    delete). Uses the same endpoints the File Manager front end calls.
