- * Optional contract a shipping rate driver implements to declare whether

+ * Every shipping rate driver this module registers implements this to
+ * declare whether it fulfils via carrier delivery or in-store pickup —
  * Modules\Core\Shipping\Carriers\Acs\AcsRateDriver and BoxNowRateDriver
- * are unambiguously carrier-only, so this is a hardcoded fact about the
- * driver, not something a merchant should have to configure per row.
- *
- * table-rate-shipping's own generic drivers (flat-rate, ship-by,
- * free-shipping) don't implement this — they're genuinely ambiguous (a
- * merchant could configure one for either carrier delivery or store
- * pickup), so Modules\Core\Shipping\Support\FulfillmentType::resolve()
- * falls back to ShippingMethod.data['fulfillment_type'] (still merchant-
- * overridable) only for drivers that don't implement this contract.
+ * are unambiguously carrier-only, Modules\Core\Shipping\Carriers\
+ * StorePickup\StorePickupRateDriver unambiguously store-pickup, so this
+ * is a hardcoded fact about each driver, never something a merchant
+ * configures per row. See Modules\Core\Shipping\Support\FulfillmentType::
+ * resolve(), the single source of truth this feeds.
