Oh wait, my code does take that into account.

There's a lot of code, stop laughing.

Looks like I can't fetch some users' keys using my server key. I have to use the key for the person's inbox they posted to? Rude.

TIL that a bunch of these services don't have paths for their actors' public keys and when they say `/path/to/user#keyId` they're saying "it's in the Actor object instead", and not that somehow magically squeezing the URL fragment into the request will yield a goddamn thing.

Yes, it was in the book. There's a lot in the book.

Watching #ActivityPub requests roll into my new app in a steady stream and be met with an even steadier stream of errors, heh
