# People Slice This is the richest slice in the app and the main relationship workspace. - `domain/person_models.dart`: person profile, facts, dates, preference signals, and source-link models. - `presentation/people_view.dart`: main people workspace screen. - `presentation/providers/people_ui_state.dart`: list/search/filter selection state for the people workspace. If you want to extend person intelligence, start in `domain/` for data shape and then wire the UI through `presentation/`.
