   The mechanism is implemented in #64 (draft); the UX half of your issue isn't, so flagging both.

   What exists:

   • An offer rule with "requires a ticket ID" + source credit + "move my ticket", configured per event in the promo dialog.
   • Credit is based on TicketExtra.paid_value — what the ticket actually cost, not its ticket type's list price — so a chain of upgrades (A→B→C) can't inflate its own value.
   • Credit is capped at the target ticket's price: if the difference is zero or negative the upgrade is free, never a payout.
   • move voids the source ticket and releases its seat when the upgrade is paid; both tickets record the link (upgraded_from / upgraded_to).
   • Cross-currency upgrades are blocked, as are already-consumed, deactivated and refunded source tickets.
   • POST /maintenance/backfill-paid-values reconstructs paid_value for tickets sold before that field existed, so historic tickets can be upgraded too.

   What's missing — your "UX flow should make it obvious":

   • The buyer has to type <their ticket ID>, <offer code> into the same comma-separated promo box used for ordinary discounts. Nothing on the event page or on their ticket tells them an upgrade is available or that this is how to claim it.
   • The buyer's ticket page shows the QR and a copy-link button but never prints the ticket ID as text, so getting the ID means decoding the QR yourself.
   • Ownership is possession-based: the ticket ID is the bearer token, so anyone holding it can spend the upgrade.

   Proposal: keep the promo machinery as-is and add a small "Upgrade this ticket" block on the ticket page that lists the offers matching that ticket's type, shows the computed difference, and pre-fills the ticket ID — plus print the ticket ID as text. Happy to take that as follow-up work if the direction's agreed.
