FROSTYVERSE TEST H2-089
SINGLE-MODE D EQUIVALENCE + FROSTY'S PAIR-FIELD SIDEQUEST

MAIN TEST
H2-038 mechanically derived the magnitude of the existing dispersion response D
from H-023/H-025 motion strain plus H-041 linear FrostSegment stored work.
H2-086 showed that the H-019/H-021 six-support release/opening ledger contains
four one-transverse-mode work units.

H2-089 asks the remaining narrow question:
  Is one transverse release/opening work unit actually the same mechanical work
  unit as D?

The test deliberately distinguishes:
  A) direct coefficient-free equality,
  B) same quadratic elastic-work family but missing coordinate identification,
  C) different work/scaling family.

No conversion between the motion-strain coordinate and node-opening coordinate
is fitted. A same-family result must not be mislabeled as a full amplitude derivation.

FROSTY'S SIDEQUEST
The user proposed that both domains may matter during the six-support handoff:
source-body deformation belongs to the source domain, while the moving SFN/FrostStructure
carries the second domain. H2-089 therefore directly retains and extends the H2-088
PAIR_TOTAL_EVERYWHERE candidate:

  field scale = M1 + M2
  relative orbit scale = M1 + M2

The same rule is applied to:
  Sun + Mercury
  Sun + Venus
  Sun + Icarus
  Earth + Moon
  Jupiter + Europa

Controls:
  SOURCE_ONLY_LEGACY
  SPLIT_SOURCE_FIELD_PAIR_ORBIT

The SideQuest first runs an FV-only mass-homogeneity stress. For a fixed orbit
shape, it asks whether P(q)/(1+q) remains invariant as q=M2/M1 rises through 1.
Only after that FV structural seal are the selected real-pair GR rulers reported.

IMPORTANT GUARDRAIL
PAIR_TOTAL_EVERYWHERE is an effective relative-system candidate. A pass does NOT
by itself prove that an orbiting body exerts a literal self-force on itself or
that two separated FrostGrid fields have already been microscopically derived.

LOW-e NOTE
Venus and Europa remain numerical-conditioning controls. Mercury, Icarus, and
Moon are the robust real-pair comparison set.
