For every released inner region r and every natural-number scale k, any compact positive integer frame admits three physical fine words x_0, x_1, x_2 with the exact central child histograms. Write x_i(q) for the numeric entry in mode i at physical coordinate q, and C_i(c,w) for the number of split positions in cell c carrying child word w. Then

∑i=02xi(q)=2,Ci(c,w)=k μr,i(c,w).\sum_{i=0}^{2} x_i(q)=2, \qquad C_i(c,w)=k\,\mu_{r,i}(c,w).i=0∑2​xi​(q)=2,Ci​(c,w)=kμr,i​(c,w).

Here the split uses the frame's own position enumeration, and mu is the released compact central profile. Every split child word also has the grade prescribed by its cell.

The result keeps the reference address and enumeration already chosen by the frame. It assumes neither a tolerance nor a repair budget, and it handles cells of zero mass. It is conditional on the supplied frame; it does not assert that a frame exists at scale zero. Positive-scale frame existence is a separate accepted theorem.

Exact histograms imply membership in every central child window of nonnegative radius for a step constructed from the same frame. This supplies the supported-window witness used to prove that a graded tolerance stage has at least one type. The theorem does not assert a matrix-volume bound or complete the recursive joint construction.

New finite-data realization lemma for the released compact profiles. It uses Robertboy18's joint-histogram realization theorem p2m:theorem/0703f3f2-a79a-4e3a-93bb-a0f7d154209c (accepted proof p2m:solution/d4f8e3aa-913a-41cd-828d-e065df03ae7b), the compact tables p2m:theorem/60610bd3-0675-4be4-a731-ca71c173a5bc contributed by marwahaha, and the common integer profiles p2m:theorem/3d489536-019f-46c1-b6c3-52ee24f948d0 contributed by Robertboy18 from raresbuhai's released exact seed p2m:theorem/cb80ec03-0b0a-4b6c-a75e-ca788b94d914. The local cell-fiber cardinality argument is copied verbatim from raresbuhai's accepted proof p2m:solution/50983a64-7873-4293-b499-5e40f94a5eef of p2m:theorem/42ce2054-4a77-4ab8-872d-5d87385fc333. The six accepted positive-profile correspondences transport the joint counts to the 88 compact labels. The existing positive-frame existence result is p2m:theorem/8aa8d8f3-b4a4-4716-9fdf-b63581bd2434.
