The ranking is rules, not opinion — here is exactly how an answer set becomes a ranked result and a safe next check.

Each answer maps to transparent rules; the rules that fire and their weights are shown as a trace so the ranking can be inspected rather than merely asserted.
A GFCI requires supply power to reset, so if supply status is unknown the diagnostic fails closed instead of ranking a cause.
The homeowner boundary is observation, unplugging accessible loads, and stopping use when the pattern remains unresolved. Opening the device, moving conductors, or replacing wiring is outside scope.

Where to stop. Resetting once, unplugging accessible loads, and plug-in testing are the homeowner-safe boundary. Do not open the receptacle box, check terminals, move conductors, or attempt LINE/LOAD correction. Water plus electricity is a shock hazard; do not keep resetting a wet outlet. Persistent or wiring-related conditions go to a licensed electrician. This is general information, not a quote and not a substitute for a licensed electrician.
Electrical Fault Check provides general diagnostic information only. It is not professional advice, not a quote, and not a substitute for a licensed electrician. Do not work on live wiring. If you see smoke, sparks, burning smell, heat, shock, water exposure, or repeated tripping, stop using the circuit and contact a licensed electrician or emergency services as appropriate.
