## Choices
### 1. Map to User.LoginName by AsLoginName()
### 1. Map to User only
1. We map PersonId AsLoginName() to User.LoginName.
Triggering forgejo actions stays as is, no new model & persistence is introduced.
1. We map PersonId AsLoginName() (e.g. 13-some.instan.ce) to User.LoginName.
2. We accept only URIs as Actor Items
3. We can lookup for federated users without fetching the Person every time.
4. Created User is limited:

### 2. Map to ExternalLoginUser
### 2. Map to User-2-ExternalLoginUser
Would improve the ability to map to the federation source.
But login Propagation stuff is not going to be used and will maybe be harmful.
1. We map PersonId.AsWebfinger() (e.g. 13@some.instan.ce) to ExternalLoginUser.ExternalID. LoginSourceID may be left Empty.
2. We accept only URIs as Actor Items
3. We can lookup for federated users without fetching the Person every time.
4. Created User is limited:
1. non functional email is generated, email notification is false.
2. strong password is generated silently
3. User.Type is UserTypeRemoteUser
4. User is not Admin
5. User is not Active
5. Created ExternalLoginUser is limited
1. Login via fediverse is not intended and will not work

### 3. Map to FederatedUser
### 3. Map to User-2-FederatedUser
Would improve the ability to map to the federation source.
Would improve the ability to map to the federation source. But we will have a additional model & table for FederatedUser
1. We map PersonId.asWbfinger() to FederatedPerson.ExternalID (e.g. 13@some.instan.ce).
2. We accept only URIs as Actor Items
3. We can lookup for federated users without fetching the Person every time.

### 3. Map to new FederatedPerson and introduce a common User interface
Cached FederatedPerson is mainly independent to existing User. At every place of interaction we have to enhance persistence & introduce a common User interface.
1. We map PersonId.asWbfinger() to FederatedPerson.ExternalID (e.g. 13@some.instan.ce).
2. We accept only URIs as Actor Items
3. We can lookup for federated persons without fetching the Person every time.
