Q2 · The CoconutSichuan earthquake
Known quake zone; tofu-dreg schools turned a tail into a certainty.
The rare, high-impact event that was always coming, and was always going to be called unforeseeable afterwards.
Why this room
The hazard itself (a mapped fault with historical precedent and a roughly linear, per-building payoff) is textbook Q2, known and simple, but corruption that replicated the same structural weakness across thousands of nominally independent schools destroyed the independence assumption, so the tail outcome behaved like a fat, correlated loss concentrated almost entirely on one building class rather than a diversified, containable one.
