Direct Auger measurements
The argument
Because Auger measures ground-level muon signals well above hadronic model predictions, and because Auger hybrid data still demand larger ground-level hadronic signals even when model shower-maximum scales are shifted deeper, the highest-energy air-shower data directly exhibit a muon excess that mis-modelled composition or shower-maximum scales cannot fully absorb.
Does it work?

Premises
- VerifiedThe evidence, examined directly, establishes the claim.constitution →Auger measurements show ground-level muon signals well above hadronic interaction model predictions
- SupportedThe evidence favors the claim, but the examination is incomplete or the evidence is indirect.constitution →Auger hybrid data are best described when hadronic model predictions are shifted to deeper shower maxima and larger ground-level hadronic signals

The inference goes through: if Auger's ground-level muon signals exceed model predictions and the excess survives even when shower-maximum scales are shifted deeper, then mis-modelled composition cannot fully explain it and a genuine muon discrepancy follows for the highest-energy showers. The argument lives on the Auger muon measurements themselves, now verified across three independent measurement lines, and on the hybrid-data finding that larger hadronic signals are still required after the shower-maximum shift. The residual excess in the most conservative recent analysis is around 15 to 25 percent, smaller than earlier estimates but still highly significant, so the argument's force concerns existence more firmly than magnitude.

The argument lives or dies on the Auger muon measurements themselves and on the hybrid-data finding that larger hadronic signals are still required after the shower-maximum shift; both rest on published Auger analyses and neither is credibly disputed, though the residual deficit they imply is smaller than earlier estimates.
