## Known state

The three workbenches define clear comparison problems, but ASD clock responses, the muon statistical map and the joint high-speed source–probe model remain open. The registry has no QUANTITATIVE DISCRIMINATOR. This is a cross-module research deliverable, not a new physical result.

## Required deliverable

Choose a fixed apparatus, observable, theory version and parameter domain. Independently calculate $O_{\rm ASD}$ and $O_{\rm comparison}$ for the same readout, obtaining $\Delta O$. Supply errors, correlations, identifiability, calibration and a rejection region. Separate independent inputs, derived outputs and fitted parameters.

Release code, data, expected outputs and checksums. If results coincide or nuisance parameters absorb the difference, deliver a non-discrimination result. If closure fails, identify the missing equation.

## Routes not to repeat

Do not substitute user-entered amplitudes, standard curves, published anomalies or instrument precision for an ASD derivation. Do not redefine the observable or expand parameters after seeing data while claiming that the original prediction passed.
