After the migration 20260625_0009_align_member_id_with_auth.sql aligned members.id == auth.users.id and the user rebuilt the iPad app, Claim Your Seat STILL failed with:
diag_full_jwt() returns current_setting('request.jwt.claims', true)::jsonb — the JWT claims that PostgREST parsed from the request. [:] (empty claims object) means PostgREST parsed NO JWT claims from the request. The Authorization header either: 1. Wasn't sent (most likely) 2. Was sent with the wrong format (the supabase-swift SDK uses Bearer <token> format — PostgREST requires this exact format) 3. Was sent but PostgREST couldn't parse the JWT
CREATE OR REPLACE FUNCTION public.diag_full_jwt() RETURNS jsonb LANGUAGE sql STABLE SECURITY DEFINER AS $$ -- SECURITY DEFINER means the function runs with the caller's -- privileges, not the function owner's. This lets the function -- read request.jwt.claims even when called from anon. SELECT current_setting('request.jwt.claims', true)::jsonb $$;
The durable fix's invariant ("RLS can join members to auth.users on id == auth.uid() without a lookup") is correct, but RLS only works if auth.uid() returns the right value. auth.uid() returns NULL when the JWT isn't reaching PostgREST. The invariant holds, but the auth.uid() check fails for a different reason than expected.
