FROSTYVERSE H2-091 — RUN THIS FIRST

PRIMARY TEST — USER-PREFERRED EIGHT-NODE IDEA
  A deformed FrostCell is defined by eight corner FrostNodes.
  Test whether all eight are physically engaged during FrostTransit and whether
  each independently owns one H2-090 source/destination half-ledger (1/2 D):

      8 FrostNodes x (1/2 D) = 4 D

  The test does NOT assign 1/2 D to every corner by assumption.  It first uses
  the inherited eight-node trilinear FrostCell geometry, then independently
  decomposes the actual H-017 twelve-FrostSegment work so duplicated work cannot
  masquerade as an eightfold multiplicity.

FROSTY'S SIDEQUEST — FOUR CROSSED-FACE NODES
  The transit direction mechanically chooses the actual exit face.  Its four
  corner FrostNodes are then tested for independent full-D ownership:

      4 crossed-face FrostNodes x D = 4 D

  Edge/corner exits are negative controls; no arbitrary face is selected.

The six incident supports around every FrostCell corner are also inventoried.
The 24 external neighboring FrostSegments are surfaced explicitly, but H2-091
will not invent a new whole-cell activation/work law for them.

FV-only mechanical test.  No GR/precession target selects the result.
H2-089 M1+M2 pair-total bookkeeping stays frozen.
