E.11:5.5 - A better first-click rate can make discovery worse

Suppose retrieval ranks WORKING-DOCUMENTS first whenever a diagram is mentioned and the first-click rate rises. Follow-up comparison shows that more readers now open document-use patterns while the architecture subject or selected structure is still unsettled, so first-result mismatch and wrong-turn returns also rise.

The visible navigation measure improved while the intended value worsened. Keep first-click rate as telemetry, apply E.13 to the substitution, and judge the guidance by recoverable situation fit, first-result fit, and wrong-turn cost rather than by the click measure alone.
