Earned during v0.191.1's own live validation. After the customer had been warned, a restart produced ZERO fillwatch lines — equally consistent with 'ran and chose silence' and 'never ran'. Proving the checker was alive needed a deliberate crossing into the critical band. For an edge-triggered check the quiet run IS the healthy steady state, so that ambiguity is permanent rather than rare. Check now logs a per-RUN summary on every run, counting unreadable separately from healthy so a drive that has quietly gone unreadable cannot read as 'all fine'.
