How a season gets built

  • Teams and divisions: Teams come straight from registration; divisions are computed from age groups and counts and can be overridden.
  • Fields and blackouts: Each venue carries its own available days and times, plus blackout windows for permits, holidays and team conflicts.
  • Generate and review: The solver builds the full season and lists every conflict before anything publishes.
  • Publish and run: Scores feed standings, playoffs become brackets, umpires are assigned per game with payout statements.
  • Rainouts: A weather operations view with radar and a field map, and reschedules that respect the same rules.
