SportEvent

Interface

Contest-level cross-sport event (Blueprint 1 §3.6) — the analogue of one Race or one FootballMatch (never a grouping). Carries only fields that genuinely unify across sports; the cross-sport events() / union Event surface is deferred until a real consumer exists (BP4 §4.8).

Fields

Field	Args	Type	Description
id	—	ID! required	—
sport	—	Sport! required	—
competition	—	Competition	Nullable on the interface (covariance): not every contest belongs to a competition.
scheduledTime	—	DateTime	Nullable for the same covariance reason as competition (POD-845): an F1 session can exist before the provider publishes its time (motorsport_sessions.scheduled_time is nullable), so the interface cannot promise one. Football, tennis and basketball each still declare DateTime! on their concrete type — their columns are NOT NULL, so they guarantee it honestly and a consumer querying those types directly is unaffected. Only a consumer reading through this interface must handle null, which is the truth.
lifecycle	—	EventLifecycle! required	—
venue	—	Course	—
