Root Cause Map
The rule map is where downtime turns into executable restart work.
This lane maps failure-mode requirements to evidence targets, owner lanes, readiness, and blockers that still prevent safe restart routing.
| Failure Rule | Target Evidence | Owner | Readiness |
|---|---|---|---|
| Bearing inspection proof Motor overheat Mechanical restart safety | Inspection note plus thermal trace and reset history | Maintenance Control | yellow |
| Valve integrity confirmation Hydraulic collapse High-load restart risk | Valve inspection plus pressure-trend confirmation and safety walkthrough | Reliability Engineering | red |
| Calibration and QA release Sensor drift Release quality confidence | Calibration log and signed QA release note | Quality Engineering | yellow |
| Safety validation replay Interlock fault Protected restart | Interlock replay log and safety validation signoff | Controls Team | green |
