Route work across tenants and groups.

Multi-entity setups keep separate books while sharing one Cortena workspace.

## Patterns

Route by entity, shared service center, or group-level matrix. Keep audit trails per tenant.

## Access

Limit users to the entities they own unless they operate a shared AP desk.
