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.

What it said at the end

Done. Tenant isolation via RLS is fully implemented and verified end-to-end through the REST API with real user JWTs. ## What was applied (one transactional SQL migration) **Helper function** `public.is_org_member(uuid)` — `SECURITY DEFINER` membership check for the calling `auth.uid()`, used by the `org_members` policy to avoid infinite recursion (RLS on `org_members` referencing itself). Granted to `authenticated`/`anon` only. **RLS enabled + policies:** - **`tickets`**: - SELECT: any member (admin or member role) of the ticket's org - INSERT: only `role='admin'` members of the target org (`WITH CHECK`) - UPDATE: must be a member to touch the row (`USING`) and only admins pass (`WITH CHECK`) — also prevents moving a ticket to an org the admin isn't admin of - DELETE: only `role='admin'` members - **`org_members`**: SELECT only within your own org; no write policies for users (service role still manages memberships) - **`orgs`**: SELECT for authenticated members of that org; no policies granted to `anon`, so anonymous sees nothing ## Verification results (REST API, real JWTs) | Test | Result | |---|---| | uma (Acme admin) reads tickets | ✅ 3 Acme tickets only | | vic (Acme member) reads tickets | ✅ 3 Acme tickets only | | wen (Globex) reads tickets | ✅ 2 Globex tickets only | | anonymous reads tickets/org_members | ✅ `[]` | | org_members visibility | ✅ each user sees only their own org's member list | | member INSERT/DELETE, admin→foreign-org INSERT, anon INSERT | ✅ all denied (403 or no-op, row confirmed intact) | | admin INSERT/UPDATE/DELETE in own org | ✅ 201/200 success | | admin moving ticket to foreign org | ✅ denied (403) | Data is untouched — the temporary test tickets were deleted, final state confirmed as the original 5 tickets (Acme 1–3, Globex 4–5). Test tokens and temp files were cleaned up.
