A generated service call has an uncertain effect

A test service exposes a fictional operation set_interval(target, seconds, expected_revision, attempt) and a query for an attempt’s outcome. The engineer is permitted to change meter-2’s sampling interval to 10 seconds. Its current revision is 81.

The model proposes seconds=10000, having reused a millisecond value. The binding step compares the requested duration with the actual seconds field and constructs 10 from the supplied unit conversion. It obtains revision 81 from the current target rather than copying another meter’s cached revision.

The request with attempt A17 is accepted, but its reply is lost. The executor queries A17 under the supplied contract. That return identifies meter-2, revision 82 and interval 10 seconds. The next report uses those observed values and closes the change task; it does not issue another mutation.

If the attempt query instead reports an unknown outcome, the task remains unresolved. If a fresh read shows an independently changed revision before invocation, the expected-revision condition fails and the engineer reconsiders the change against that state. Neither case becomes success because the generated explanation is convincing.

For a request merely to explain a current configuration, an already applicable observation may suffice. Reissuing a state-changing call would add no needed result.
