Join the waitlist
Puts somebody in line before the product opens. Unconditional 202, like every public endpoint that takes an address, and it mints no session — the developer lets people in from their panel and the person hears about it by email.
The entry hangs off a contact, so first-touch attribution, the merge and the audit trail apply to it from its first minute. Joining twice keeps the first place in line and the first answers.
Only in an environment that is holding a line: an open one answers 409 waitlist_closed rather than collecting into nothing.
