yeah so if I looked at a log of all that, wouldn’t I have a “extra observer” detector, then?

You could detect decoherence in the system, that doesn't indicate a human observer, however.

That process is, however, used to protect cryptographic keys, transfered between banks. A hostile observer collapses the state early. The observer gets the key instead of the 2nd bank, which is extremely conspicuous to both banks.
