 - [Phase ?]: dispatchPush uses sub.id (not a separate dbRowId argument) — 2-arg signature matches existing test
 - [Phase ?]: coalesceListPush dispatch signature is (listId, actorId, count) — test scaffold canonical; richer payload deferred to Plan 05-05 caller
 - [Phase ?]: notifyListChange fires for all list/item mutations except reorder (position) and list-create per D-01
+- [Phase ?]: D-05-06-crossjoin: Drizzle cross-join in reminderScheduler pairs shared events with all pushSubscriptions; grouping by uid post-join ensures full fan-out per deduped event (reminderScheduler.ts)
