Multi-region model routing for data residency

Shipping agents into regulated markets means proving where data goes. We made residency a property of the router, not a deployment headache.

Residency as routing

Each step carries context about the user's region. Routing rules pick a model and provider that satisfy residency requirements automatically — EU data stays on EU infrastructure.

Failover without leaks

When a provider degrades, Capsule fails over only to endpoints that satisfy the same policy, so reliability never comes at the cost of compliance.

Latency wins too

Routing to the nearest compliant region usually means lower latency as a bonus — the right call is also the fast one.
