Reference geometry of the actual signed family #

Every singleton retains the original primary label, phase, native view, and current-state request. Reindexing its dependent payload changes only the proof of the reference-band equality. The seven reference-geometry fields below come from these primitive identities; no equality of output physical fields or native regularity is assumed.

Native regularity of the actual signed cut sources #

The dyadic factor is retained literally. The estimates below first turn the actual radial flat-weight classes into bounded jets, including at the radial edges; no smooth continuation of the unmasked request at a dyadic face is assumed.

Exact native-source factorization for the actual signed family #

The primitive state, primary choice, request, and lattice copy are unchanged. The identities retain the one Gaussian already present in the native cutoff. They hold on the whole native coordinate space, before any smoothness claim or own-band/harmonic gate is applied.

Literal flat dyadic products from locally bounded interior jets #

The unmasked factor is smooth only in the open dyadic band. Its actual interior jets are locally bounded at each face. Flatness of the fixed cutoff then proves smoothness and vanishing of all jets of the literal product, without assigning new values to the unmasked factor outside the band.
