-- Vestige Pro waitlist capture.
--
-- One row per signup from the public /dashboard/waitlist form. The form POSTs
-- through the `waitlist-join` Edge Function (service-role), NOT directly to this
-- table, so Row-Level Security stays closed to anon clients while the function
-- can insert. We keep the table minimal and queryable for launch-day export.

-- One signup per email address. ON CONFLICT in the function turns a re-submit
-- into a friendly "already on the list" instead of a duplicate row or an error.

-- RLS ON, no anon policies: the anon/public key can do NOTHING here directly.
-- Only the service-role key used inside the Edge Function bypasses RLS to insert.

comment on table public.waitlist is
    'Vestige Pro launch waitlist. Inserted only via the waitlist-join Edge Function (service-role). RLS blocks all anon access.';
