@evan Hi - I'm trying to get `ap` working with my server, so implementing FEP-d8c2 for login. Shouldn't the client Application at https://github.com/evanp/ap/blob/main/docs/client.jsonld have an inbox property? I realise an inbox may not make a lot of sense for a client but it's a MUST property in the ActivityStreams spec and the library I'm using throws an error when I try to load your Application JSON-LD. Or if you think it's OK to skip the inbox property for the client, would that be worth you adding to the FEP?
