10.3 Data Layer
createPeopleService() returns a cached singleton — either PeopleService (live Graph) or MockPeopleService (local development). GraphCache uses in-memory storage backed by sessionStorage. All user queries filter to userType eq 'Member'.
10.4 Security and Data Boundaries
Directory data is read-only from Microsoft Graph and remains in your tenant. People Hub does not copy employee profiles to an external database. Optional subscription checks call the Chronodat subscription API for licensing only.
