Failover is confined to the eligible set
Failover retries only within the declared jurisdiction.

Design
How this part works
Eligible-set failover
When a provider degrades, the router retries against other providers that pass the same policy. Ineligible providers cannot receive retries. The pool can shrink; it cannot widen past a border.
Documented refusal semantics
If the eligible set is exhausted, the request fails with the constraint that emptied it.
Model and region coverage
Different models have different in-region coverage. The catalogue states coverage per model and region.
In-region capacity
Capacity is planned as headroom inside the boundary. The platform does not offer cross-border spillover.

Comparison
Boundary-first routing
Example availability-first gateway
- Widens the provider pool under load
- Boundary relaxed by an on-call decision
- Coverage gaps found in production
- Pool shrinks, never widens
- Refusal semantics fixed in advance
- Coverage gaps visible in the catalogue
