# These tests exercise the REAL stack (GoTrue auth + Postgres RLS) instead of
# mocks. They are the harness you re-run on every Supabase image bump to prove
# the auth↔API contract and the deny-all RLS firewall still hold.
#
# Usage:  supabase start   # in the repo, once
#         npm run test:stack        (from backend/)
