Contract
- MockAgent intercepts requests by origin and consumes each registered interceptor exactly once by default, rejecting subsequent unintercepted requests with MockNotMatchedError when net connect is disabled.
- Interceptors configured with .times(n) or .persist() allow repeated matching before being exhausted.
- Dynamic reply callbacks in interceptors receive the incoming request options including method, path, headers, and body.
- assertNoPendingInterceptors verifies that all registered interceptors were dispatched, throwing an UndiciError if any interceptor remains pending.
