A six-person crib team near Onsan-eup joined a Fleet Ledger cohort after losing track of loaned torque tools across weekend overtime. They standardized three custody verbs, ran Module 6’s yard walk, and posted the handoff card on the cage door.
Result after five weeks: weekend “missing tool” tickets dropped from roughly eleven to four. They still struggle when contractors bring unlabeled cases — a gap the course openly does not solve alone.
