Step 1
Upload participant list
Import the UltraSignup CSV. That's your match-set and contact directory.
Step 2
Photograph each bag
One photo per bag, bib number up. Claude Vision reads the bib and matches it to the list.
Step 3
Notify runners
One message per matched runner with a link to their bag and four simple choices.
Step 4
Work the queue
Ship, pickup, donate, release, or auto-dispose after the deadline. No inbox, no pile.
