When checking for duplicate signups, we looked at SSN, which can have varying formats, making it possible to bypass the dedup check. Now, we look at the unicore id, which is guaranteed to be unique and has a consistent format.

  • Store unicore_id on signup
  • Dedup on unicore_id instead of ssn
  • Add tests for signup
