Headers and decoded JWT claims do not authorize tenant access. Authenticate before extraction, authorize membership, use a restricted non-owner database role, and apply RLS policies. Raw SQL requires explicit transaction-local context. Repository main can contain changes not yet published to npm; compare its version and release notes with the installed package.
