FROSTYVERSE TEST H2-088 — UNIVERSAL TWO-BODY PRECESSION FORMULATION AUDIT

QUESTION
Can the same FV precession law and the same mass bookkeeping be used from a star/planet pair down to a planet/moon pair?

FROZEN PRECESSION CLOSURE
  H_total = H_stable + C_release * D
where C_release is re-measured from inherited H-019/H-021 six-support release/opening work and is not fitted to any astronomical body.

SYSTEMS
  Sun + Mercury
  Sun + Venus
  Sun + 1566 Icarus
  Earth + Moon
  Jupiter + Europa

PREDECLARED MASS LANES
SOURCE_ONLY_LEGACY
  Field depth, orbital motion scale, and period use M1 only. This reproduces the inherited test-particle-like FV bookkeeping.

PAIR_TOTAL_EVERYWHERE
  Field depth, orbital motion scale, and period use M1+M2 everywhere. This is the simplest same-formula two-body candidate.

SPLIT_SOURCE_FIELD_PAIR_ORBIT
  Field/clock depth remains sourced by M1, while relative orbital motion and period use M1+M2. This tests the physically distinct idea that the field belongs to the source while the separation coordinate follows the pair total mass.

REFERENCE
All lanes are compared to one leading two-body relative-orbit GR ruler using M1+M2. This avoids changing the target formula from one pair to another.

SELECTION
Mercury, Icarus, and Moon are the robust lane-selection set. Venus and Europa are retained as low-eccentricity controls because previous tests showed their extracted apsidal response is more sensitive to numerical coordinate conditioning.

A small body/source mass-ratio stress ladder is also included to show how each universal lane behaves as q=M2/M1 rises from test-particle values toward and beyond the Moon/Earth ratio.

LIMITATION
Even if a pair-total or split lane transfers best, that only establishes a useful universal effective two-body bookkeeping rule. It does not by itself derive fully reciprocal FV gravity or the microscopic D/release-work equivalence.
