+-- 004_event_triggers.sql — event-driven schedule triggers.
+--
+-- Until now schedules only supported cron. This migration adds:
+--   * trigger_kind = 'event' schedules, powered by a CEL expression over
+--     the event bus. Example: players_online == 0
+--   * optional sustained-state: fire only after the condition has been
+--     continuously true for N seconds. Enables "idle shutdown if 0 players
+--     for 30m" without firing every 60s when the polled player count is 0.
+--
+-- cron_spec becomes nullable so event triggers can exist with NULL there.
+-- Exactly one of cron_spec / event_spec is populated; the application
+-- enforces this.
+
+ALTER TABLE schedules ALTER COLUMN cron_spec DROP NOT NULL;
+
+ALTER TABLE schedules
+    ADD COLUMN event_spec             TEXT,
+    ADD COLUMN event_sustained_seconds INTEGER NOT NULL DEFAULT 0;
+
+CREATE INDEX idx_schedules_trigger_kind ON schedules(trigger_kind);
