## AI overview

The article argues that token isolation and storage architecture are only the starting point for multi-tenant OAuth. The harder, ongoing problems include refresh races, key rotation, provider-wide revocations, token expiration, and external revocations without webhooks. It also explains how envelope encryption and per-tenant key contexts can support bridge-style isolation.

Storage architecture is the half you can finish. The refresh loop, key rotation, and revocation are the half that never does.
