+-- Migration 013: Row-Level Security for scheduled_events
+-- ============================================================================
+-- Enables RLS on the scheduled_events table so that users can only see
+-- their own events at the database level. This is defense-in-depth:
+-- the API already filters by user_id, but RLS ensures data isolation
+-- even if there's a bug in the application layer.
+--
+-- The policy allows all operations when app.current_user_id is NULL
+-- (backward-compatible fallback for queries that don't set the variable).
+-- When the variable IS set, only rows matching the user's ID are visible.
+-- ============================================================================
+
+ALTER TABLE scheduled_events ENABLE ROW LEVEL SECURITY;
+
+DROP POLICY IF EXISTS scheduled_events_user_policy ON scheduled_events;
+CREATE POLICY scheduled_events_user_policy ON scheduled_events
+  FOR ALL
+  USING (
+    user_id = current_setting('app.current_user_id', true)::uuid
+    OR current_setting('app.current_user_id', true) IS NULL
+  );
