+Supabase Tenant Extension for Hindsight
+
+Validates Supabase JWTs and maps authenticated users to isolated memory banks.
+Each user gets their own PostgreSQL schema based on their Supabase user ID.
+
+This extension enables multi-tenant memory isolation for applications using
+Supabase Auth - each authenticated user's memories are stored in a separate
+schema, ensuring complete data isolation.
+
+Features:
+    - Local JWT Verification: Validates tokens locally using JWKS public keys
+      (no network call per request)
+    - Automatic Schema Isolation: Each user gets {prefix}_{user_id} schema
+    - Zero User Management: Leverages your existing Supabase Auth setup
+    - Production Ready: Includes health checks, timeouts, key rotation handling,
+      and error handling
+    - Built-in: Ships with Hindsight, no extra installation needed
+    - Legacy Support: Falls back to /auth/v1/user endpoint for HS256 projects
+
+JWT Verification Strategy:
+    By default, JWTs are verified locally using public keys from the Supabase
+    JWKS endpoint (/auth/v1/.well-known/jwks.json). This is the Supabase-recommended
+    approach: no network call per request, fast, and secure.
+
+    If JWKS keys are unavailable (e.g., legacy HS256 projects), the extension
+    falls back to calling /auth/v1/user per request for validation. This requires
+    the service_role key to be configured.
+
+Configuration via environment variables:
+    HINDSIGHT_API_TENANT_EXTENSION=hindsight_api.extensions.builtin.supabase_tenant:SupabaseTenantExtension
+    HINDSIGHT_API_TENANT_SUPABASE_URL=https://your-project.supabase.co

+
+    # Optional
+    HINDSIGHT_API_TENANT_SCHEMA_PREFIX=user  # Default: "user" (creates user_<uuid> schemas)
+
+Usage:
+    Clients pass their Supabase JWT in the Authorization header:
+
+    curl -H "Authorization: Bearer <supabase_jwt>" \\
+        https://your-hindsight-server/v1/default/banks/my-bank/memories/recall
