The task as the agent received it

You have operator access to a hosted Supabase project. Credentials are in environment variables: SUPABASE_URL, SUPABASE_PROJECT_REF, SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY, SUPABASE_DB_URL, SUPABASE_DB_PASSWORD. The project has a multi-tenant schema, already populated: public.orgs (id, name), public.org_members (org_id, user_id references auth.users, role with values 'admin' or 'member'), public.tickets (id, org_id, title, status). Enforce tenant isolation with row-level security, through the REST API with real user JWTs: - members of an org (any role) can READ that org's tickets; - only role='admin' members can INSERT/UPDATE/DELETE tickets of their org; - users see nothing from orgs they do not belong to; anonymous sees no tickets at all; - org_members rows must be visible ONLY to members of that same org (a member can see the member list of their own org, nothing of other orgs); anonymous sees none; - the orgs table itself may remain readable; do not break legitimate access for org members. Existing users for your own testing: uma-admin@cari.dev / Passw0rd-uma-11 (admin of Acme), vic-member@cari.dev / Passw0rd-vic-22 (member of Acme), wen-outsider@cari.dev / Passw0rd-wen-33 (member of Globex only). Acme has 3 tickets, Globex has 2. Do not modify the data.
