So if you were at an auction and you found the plans for Frank Lloyd
Wright's unknown, unbuilt house -- one that fundamentally defines his
architectural style and that just happens to meet existing building
code -- then you could not build it because you would have to rely on
FLW's design?


Doesn't mean you could not build it. The "direct supervision" law just
means that no design professional could put his/her seal on that set of
drawings.

An architect/engineer could completely redraw the drawings under their own
title block/logo and then seal those drawings. Any responsible A/E would
only do so after completely checking the design.
