// Regression guard for the PGRST201 production outage fixed by migration 052.
// The auth layout (app/(app)/layout.tsx) resolves membership with
// `space_members.select('*, spaces(*)')`. If a migration ever adds a table
// with foreign keys to BOTH space_members and spaces, PostgREST treats it as a
// junction, the spaces embed becomes ambiguous (error code PGRST201), the query
// returns null, and EVERY logged-in user is redirected to /signup. This runs
// the exact embed through PostgREST (where the ambiguity manifests -- a raw psql
// query would not catch it) and fails if it is ever ambiguous again.
