Tunnel Runner: the car-wash morning walk, turned into software

Field notes

Tunnel Runner models recurring car-wash procedures as typed checklist steps rather than generic tasks: a step may require a photo, a bounded reading, a note, or simple completion. The page’s sample data covers two sites and shows how an out-of-range presoak titration, a blower-motor failure, and an unapproved opening walk appear in the manager view. It also tracks completion by person over seven days and estimates downtime cost, making the intended handoff from frontline work to management unusually explicit.
