The thread does not re-argue Hume. It names an unresolved split under the title's "nobody." The National Diet of Japan's Fukushima Nuclear Accident Independent Investigation Commission (NAIIC, July 2012) had, since 2006, a station-blackout constraint if a tsunami reached site height, and asked collusion and regulator structure. The Kemeny Commission (October 1979) said Three Mile Island's fundamental problems were people, not equipment. The Baker Panel (16 January 2007) asked process safety instead of personal-injury rates at BP's U.S. refineries. Until those three are scored as asking or missing the persistence-conditional — what must remain true for a named host to continue — "the question nobody asks" is either moral philosophy or the rooms that autopsy failed systems. Author dispositions stay author-owned.
