For ,

Every internal row and every vertex term is retained.

If has compact distributional order at most , then

on a fixed compact neighborhood of the translation support.

Every equality of actual internal distributions is respected. In particular, if , then the corresponding and all regularized values are zero.

Proof. Insert into (eq:transpose). The result is

which is the pushforward definition of (eq:origin-evaluation).

Linearity gives

Each row uses all terms of (eq:Lambda).

The tensor pairing requires at most five -derivatives and at most -derivatives. On their combined order is at most . The compact-support cutoffs have fixed derivative bounds. This proves (eq:Omega-order).

The construction begins with the actual , so a zero internal distribution remains zero at every stage.
