// 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.
