## Choices
### 1. Map to User only
Triggering forgejo actions stays as is, no new model & persistence is introduced.
### 1. Map to plain forgejo User
1. We map PersonId AsLoginName() (e.g. 13-some.instan.ce) to User.LoginName. Due to limitations of User.LoginName validation mapping may be affected by invalid characters.
2. Created User is limited:
1. non functional email is generated, email notification is false.
1. non functional email is generated, email notification is false. At the moment we have problems with email whitelists at this point.
2. strong password is generated silently
3. User.Type is UserTypeRemoteUser
4. User is not Admin
5. User is not Active
We can use forgejo code (like star / unstar fkt.) without changes.
No new model & persistence is introduced.
But we use fields against their semantic and see some problems / limitations for mapping arise.

### 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.
### 2. Map to User-&-ExternalLoginUser
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. Login via fediverse is not intended and will not work
We can use forgejo code (like star / unstar fkt.) without changes.
No new model & persistence is introduced, no need for refactorings.
But we use fields against their semantic (User.EMail, User.Password, User.LoginSource, ExternalLoginUser.Login*) and see some problems / limitations for login functionality arise.
Mapping may be more reliable compared to option 1.

### 3. Map to User-2-FederatedUser
Would improve the ability to map to the federation source. But we will have a additional model & table for FederatedUser
### 3. Map to User-&-FederatedUser
1. We map PersonId.asWbfinger() to FederatedPerson.ExternalID (e.g. 13@some.instan.ce).

Introduce FederatedUser as new & persistence, no need for refactorings.
But we use fields (User.EMail, User.Password) against their semantic, but we probably can handle the problems arising.
We will be able to have a reliable mapping.

### 3. Map to new FederatedPerson and introduce a common User interface
### 4. 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.
2. We will have no semantic mismatch.
We can use forgejo code (like star / unstar fkt.) after refactorings only.
We introduce new model & persistence.
We will be able to have a reliable mapping.
