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

Tenant isolation is fully enforced via RLS and verified end-to-end through the REST API with real user JWTs. ## What was applied (via `psql`) **Helper functions** (SECURITY DEFINER, so policy checks can read `org_members` without RLS recursion; `EXECUTE` granted only to `authenticated`): - `public.is_org_member(uuid)` — true if `auth.uid()` has any membership row in the org - `public.is_org_admin(uuid)` — true if `auth.uid()` has `role='admin'` in the org **RLS enabled** on `tickets` and `org_members` (left `orgs` as-is — still readable by everyone, per requirements), with policies targeted at the `authenticated` role (so `anon` has zero rows by default): - `tickets_select` — USING `is_org_member(org_id)` - `tickets_insert` — WITH CHECK `is_org_admin(org_id)` - `tickets_update` — USING + WITH CHECK `is_org_admin(org_id)` - `tickets_delete` — USING `is_org_admin(org_id)` - `org_members_select` — USING `is_org_member(org_id)` ## Verification results (real JWTs via `/auth/v1/token` + `/rest/v1`) | Test | Result | |---|---| | Uma (Acme admin) reads tickets | ✅ Acme's 3 tickets only | | Vic (Acme member) reads tickets | ✅ Acme's 3 tickets only | | Wen (Globex) reads tickets | ✅ Globex's 2 tickets only; explicit `?org_id=eq.<Acme>` → `[]` | | Anonymous reads tickets | ✅ `[]` | | Vic (member) INSERT/UPDATE/DELETE | ✅ blocked (403 RLS violation / 0 rows) | | Wen INSERT into Acme | ✅ blocked (403 RLS violation) | | Uma (admin) INSERT → UPDATE → DELETE temp ticket | ✅ all succeeded | | org_members as Uma/Vic | ✅ only Acme's 2 rows | | org_members as Wen | ✅ only Globex's 1 row | | org_members as anonymous | ✅ `[]` | | orgs as member/outsider/anon | ✅ still readable | | Data integrity after tests | ✅ unchanged (5 original tickets, 3 members; temp ticket removed) |
