Operations
Members, subteams, leadership, seasons, events, rosters, task management and administration.
People
The permanent roster — every person CASTOR has ever tracked. Other modules (Attendance, Training, Resources, Competition, Scouting) will all share these same identities.
Seasons
FRC seasons — required before creating official sessions or assigning people a season membership.
Everything else in Operations (subteams, leadership assignment UI, events, task management) hasn't been built yet.
