wait, hashing relies on a seed?! isn't that a salt/pepper?

to be "deterministic for the lifetime of the program" sounds like a pepper is being applied, not that the hash algorithm is different.

This is a more accurate description. The hashing algorithm is 100% deterministic, but the inputs include a random seed from the start of the program to prevent various side channel attacks and to prevent folks from erroneously relying on hashmap ordering.
