 /**
- * Sends an unverified buy-crypto user to the identity provider their country
- * routes to — Wirex countries → Sumsub, everywhere else → Didit — mirroring
- * useCardSteps so a user only ever meets one provider.
+ * Sends an unverified buy-crypto user to Sumsub, regardless of jurisdiction.
  *
- * Falls back to Didit (available everywhere) when the country is unknown or the
- * routing call fails. `fallbackProvider` accepts the backend's own suggestion
- * from GET /transfi/status, used when the client has no country of its own.
+ * Buy-crypto does not follow the card flow's country routing (Wirex countries →
+ * Sumsub, everywhere else → Didit): TransFi is a Sumsub client, so a Sumsub
+ * applicant is imported by same-vendor share token, which is the path we want
+ * every *new* verification to take. Users who already hold a Didit verification
+ * never reach here — the backend reports them as `can_share` and forwards their
+ * existing session as documents instead of asking them to verify again.
  *
  * Shared by the entry point and by the mid-flow recovery paths — TransFi can
  * reject a share as needs_kyc if the verification it received was incomplete.
