Covariance of the fixed physical primary family #
The selected primary phases, native matrices, masks, and physical labels are
those of CorrectionInitialization.ActualPrimary. The finite family is
assembled before averaging. The fixed starting threshold is retained.

All-order bounds for the retained finite prefix #
An actual class whose fields vanish after a fixed band has every exponent. The new constant is one finite sum of powers of the original positive band scales, chosen before the band and spatial point.
The finite omitted primary prefix is an actual error in every mean class, with no new threshold or primary choice and no assumption on the assembled covariance.
Every actual spatial derivative of the averaged covariance error has the same arbitrary exponent; the finite-prefix constants may depend on the chosen exponent and derivative order.
Direct interfaces for the initial mean balance #
The measured tangent covariance matches the same full virtual stress up to its actual order-two Borel remainder and the explicitly retained finite primary prefix. This supplies both initial averaged radial fluxes.
Actual closed support and separation on the common chart #
The support statements use the literal cut amplitude. Compactness of the padded native rectangle gives closed lifted support on the torus, so passing from nonzero values to topological support requires no false zero-germ claim at an edge. The common-chart disjointness statements retain the intersection with the genuine open domain.

Inactive physical labels vanish on entire slow fibers #
The radial coordinate is unrestricted here. A nonzero literal attached coefficient forces radial interior support and a nonzero actual mask, which imply membership in the fixed active-label set. On an inactive label the entire raw coefficient is therefore zero in an open slow neighborhood; this also removes its actual curl and Gaussian term.
