Signed-in users can see every class. Members can see their own spots; instructors can see every spot in the classes they teach.\nR2. Members can join a class as themselves: as `enrolled` only while the class has fewer enrolled members than its capacity, otherwise only as `waitlisted`.\nR3. Members can move their own waitlisted spot to `enrolled` only when there is room, and can leave a class by deleting their own spot. Nothing else about a spot can change.\nR4. Instructors can remove any spot from the classes they teach.\nR5. Nobody can change classes through the app. Anonymous visitors cannot see or change anything.\nR6. Server-side code using the service role keeps full access.\n\nRLSBENCH-CANARY-f9002c750838f00b\n", "schema_sql": "create table public.classes (\n  id bigint primary key,\n  title text not null,\n
