The correct cause is 'Coincidence with universal competence' and the prescribed action is `retire` — the rule prose itself already documents the prescription, so a perpetually-passing eval scenario adds no documentation value and only pays Tessl run-cost. The tile's contribution being measured is the disciplined application of the three-cause framework; baseline agents may correctly recognize the scenario is unhelpful but won't necessarily name the canonical cause or follow the rule's prescribed action.",
