"Changing file content before contact accepts the sent file causes file transmission to never complete. The file is still created in the receiver's device, with the content being five 0x00s. There's no indication of SHA512 mismatch in what was received / written to file.

One option could be to copy the file into a temp file in ~/.cwtch/ to ensure atomic file transfer operation."

Thinking about this: I believe the correct fix is for Cwtch UI to check the hash of the file and if it changes to alert the sender.

We currently don't distinugish between error and malicious corruption on the receiver side, and I don't think there is a sound way of doing this (we likely should display a "failed to download" message after some amount of time without a valid chunk packet).
