Class: UnexpectedProviderMethodError ​

Defined in: packages/core/src/providerSurface.ts:107

A provider asked for something outside the engine's declared surface.

This is an INTERNAL invariant rather than an operator error: no configuration and no node can provoke it, because the only code that reaches a guarded provider is this engine. It is thrown rather than logged so that a reintroduced call fails WHEREVER it is added, in the whole test suite, rather than only where somebody thought to look -- a permissive test double would otherwise answer it and the cost would ship.

If a method genuinely belongs in the engine, the fix is to DECLARE it in ENGINE_PROVIDER_METHODS (and say so in the README claim the tests hold to it), never to route around the wrapper.
