CP3 along the raw output of Lemma 102 over a member #

[Kol07, Lemma 102] on a triple (X, I, E) with max-ord I = 1 and a member Eʲ: blow up Z₋₁, the union of the components of Eʲ inside V(I), then push forward the inductive run on the strict transform of Eʲ (rawSeq, Hironaka.Resolution.Algebraic.BoundaryClearing.Restriction). For the statement CP3 of the embedded desingularization (Hironaka.Resolution.Algebraic.Wlo05.EmbeddedChainRelative) its centres are classified at every point for the outer data (I, E) from the inductive classification:

No smoothness of Eʲ and no inclusion Eʲ ≤ I is assumed: the passes of Step 2.1 of the proof of [Kol07, Theorem 103] have neither. This argument is not in the literature. Used in Hironaka.Resolution.Algebraic.Wlo05.EmbeddedCP3Step21 and Hironaka.Resolution.Algebraic.Wlo05.EmbeddedCP3Step22.

CP3 along the raw output of Lemma 102 over a member Eʲ for the outer data (I, E), from CP3 for the values of the inductive functor B' at the mark 1 ([Kol07, Lemma 102] and [Kol07, Lemma 62]): at a point of Z₋₁ the stratum of level 0 given by the coordinate of Eʲ; at a point of a later centre the pointwise pass centerClassifiedAt_of_comap_member on the stage inclusion, with the identities of Lemma 62.
