The tree had not compiled since its first commit: Group, DmGroup and
IGroupUsersService were referenced and never written, an IDE rename had
turned the user-settings DTO into the ViewAvatarServer enum, and the settings
were saved as an entity they no longer were.
Built now:
- Group (an ActivityPub Group actor with its own keys, members, invitation
code and optional password) and DmGroup (a conversation), with
/clientapi/group/{list,insert,update,join,leave,approve}.
- Posts and DMs: /clientapi/post/{list,insert,delete}, /clientapi/dm/{list,insert};
DM recipients are local usernames or user@host handles resolved by WebFinger.
- Invitation sign-up and login against the group's invitation code, checking
the password before any account is created.
- Federation: WebFinger, NodeInfo 2.0, actors at /peasants/{name} (Person,
Group, and an Application instance actor) with SPKI keys, draft-cavage
RSA-SHA256 HTTP signatures both ways, an inbox handling Follow (+Accept),
Undo, Create, Delete and Update, an outbox, notes at /posts/{id}, and a
persisted, retried, signed delivery queue. A post to a group is announced
by the group to its followers (FEP-1b12).
- The unused, broken typed ActivityPub models are replaced by a renderer;
NSign's HMAC setup, which could not federate, is gone.
Upgrade: net10.0, MongoDB.Entities 25.1 (instance DB API, Standard GUIDs),
Swashbuckle 10 / OpenApi 2, Serilog.AspNetCore 10, MailKit 4.18,
PasswordGenerator 3. The JWT keys are 64 bytes (IdentityModel 8 refuses
shorter for HS512). Production runs its own mongod on 127.0.0.1:27022, as
Sintopia's apps do, and deploys to privapub.thepra.dev from the build runner.
