can you point me to where you removed such a test? remember we have/had it for
resumes but for incrementals too?

does feel quirky. we should never do anything with user secrets!
how about an encrypted but small file, specific to the full which must be
decryptable before doing incrementals? obviously it must never contain the same
value to protect encryption. or reuse the full's manifest and keep it encrypted
locally too, to check encryption against.
