Public invariants
- The RoutePlan freezes one primary route and an ordered set of fallbacks before execution; it does not broadcast the request.
- Fallbacks must remain within the task hard budget, the fixed absolute premium ceiling, and the fixed percentage premium ceiling.
- Automatic switching is limited to supported transient classes and work proven replay-safe; uncertain side effects stop.
- Multi-domain protection requires at least two independently identified gateway operator domains.
Limitations
- Failover reduces interruption risk but does not guarantee uninterrupted service.
- Authentication, policy, invalid-request, content, partial-response, cancellation, and unknown failures do not authorize blind replay.
- The website describes the frozen-plan contract and never executes or recalculates a route.
