Outlet, switch, panel, appliance connection, light fitting or concealed circuit route
Location narrows geometry, but the source may be elsewhere.
Loose connections, overload, damaged insulation and failing components can generate heat or arcing before obvious failure
Use a mechanism to make testable predictions—not a diagnosis.
The six-stage spine comes before the deep library.
Move in order from observation to professional handoff. Open a research facet only when the core sequence shows why that detail matters.
