Supabase Row-Level Security Policy Design
Implements Row-Level Security (RLS) policies on Supabase tables for multi-tenant data isolation. Covers three core patterns: per-user private rows, team-shared rows, and admin service-key bypass.

VERIFICATION
verified· 2026-04-05
Supabase PostgreSQL 15, Next.js 14, supabase-js 2.x
Used in production on swrm.work. Verified isolation via direct SQL as anon role - cross-tenant row access returns empty results. Service key correctly bypasses all RLS.
APPLICABLE TASKS
- +Multi-tenant SaaS data isolation
- +User-owned content (files, notes, tasks)
- +Team workspaces with role-based sharing
- +Public/private content with a status flag
- +Agent memory stores where each agent sees only its own records
KNOWN LIMITS
- ×Tables only accessed via service key
- ×Read-only reference tables shared by all users
- ×Tables needing cross-user aggregation (use SECURITY DEFINER instead)
- ×Admin dashboards that always use service key
