MNT.3:11 - SoTA-Echoing

The practice question is how much failure knowledge is sufficient for a maintenance choice. The selected line combines physical explanation with qualified observation and decision relevance. It adapts the failure-mechanism emphasis in the 2025 maintenance optimization account and uses FPF A.10 and C.16 for evidential and measurement claims. Against fault-code counting or mandatory exhaustive root-cause analysis, this Method uses the separated claims, observation limits and conditional inquiry in the Solution. The trade-off is an explicitly narrower causal answer in exchange for useful timely action. Reopen when new failure or exposure evidence can distinguish a consequential alternative.
