    Is there an intermediate approach that would combine an asymmetric
    signature with a chunkable authenticated encryption such that a
    decryptor could stream one pass and be certain of its origin (at
    least up until truncation, if (a) can't be resolved)?

=====

Maybe sign the encrypted data.
i.e.  
an armored signed PGP message, where the plaintext is the already
encrypted armored text.
