Tau scaling

driver  a named mechanism, not a conclusion

Energy per token is the bridge from tokens to megawatts. It improves at hardware refresh points and is flat between them, so pass-through is discounted rather than absent.

coverage

3 of 3 declared anchors resolve in the model. A driver is a named mechanism rather than a graded severity or a priced claim, so its effects are deliberately smaller than either.

Arguments about this mechanism

These name its subject — they are claims about this mechanism, and they are what the eligibility gates grade.
