The Primitive-Current Reflection Is an Equivariant Rigidifier, Not Yet a Source Selector
WP837 checks WP836's surviving mixing fiber against Aspect's germ tester. For the retained primitive current (q=(1,2,3)^T), the projector
defines the unique self-adjoint three-state involution of trace one satisfying (Hq=-q): (H_q=I-2P_q). This removes the mixing-orientation ambiguity and is equivariant when (q) and (D) are transported together under real orthogonal frame changes.
Aspect's gates block the stronger interpretation. The target compares a candidate against an entire declared completion family, so that family is a native argument. Forgetting the current attachment destroys full-fiber descent. No admitted source action derives either minimization of the WP836 functional or the reflection attachment law. The exact family (D_m=mH_q), (m>0), also retains identical scale-free score and germ structure while changing the spectral threshold.
The construction is therefore a conditional mixing rigidifier attached to a
finite-completion selector. It is not yet a source-generated selector on
physical16; full weak-basis covariance, scale selection, RG and threshold
survival, and calibrated instrumentation remain open.
