+These terms are intentionally different from user-facing copy because they are hardwired to deployed contracts, API routes, storage schema, and smoke tooling.

+2. Contract ABI/function/event names: `mintMembership`, `membershipStatus`, `MembershipMinted`

+Rule: keep these technical names stable until a versioned internal refactor is planned across contracts + backend + launcher together.

 ## Change Discipline
 
 1. Copy-only rename pass: user-facing surfaces first.
