+// Tier Plans v2: item-specific entitlement. Until now a Tier Plan purchase
+// only recorded `user_tiers.plan_id` + tier rank; the actual courses/units/
+// lessons granted were re-resolved LIVE off plan_courses/plan_units/
+// plan_lessons on every access check, so editing a plan's bundle later
+// silently changed what past purchasers could access, and a Unit-only bundle
+// couldn't be distinguished from its parent Course's bundle.
+//
+// This table is the purchase-time snapshot: one row per exact item granted
+// by a given user_tiers purchase. Access checks now look up rows here
+// instead of comparing tier rank against item subscription (see hasItemGrant()
+// in controllers/client/courses.controller.js).
+//
+// item_type is STRING + CHECK, not a real ENUM, mirroring
+// products.purchasable_type (20270101000078) — CockroachDB can't create a
+// new enum type via addColumn the way createTable can.
