Function selectTransferMethod

selectTransferMethod(
    request: TransferRequest,
    direction: TransferDirection,
    uploadBytes: number | undefined,
    env: Record<string, string | undefined>,
    config?: Record<string, string | undefined>,
): {
    method: "rest" | "native" | "sftp" | "scp" | "fetch" | "ftp";
    protocol:
        | "rest-api"
        | "native-api"
        | "mac-telnet"
        | "ssh"
        | "snmp"

        | "winbox-terminal"
        | "btest";
    via: ResolvedSetting<string>;
}
Size/direction-aware method selection plus explicit---via gating. Pure (no I/O) so it is unit-testable. Throws CentrsError for the not-implemented / gated methods (examples P1–P4) and the REST write cap.
Parameters
