# n130 — the spin verdict: LARES-2 chooses the graviton
# (2026-07-11. Last night's "nothing spectacular" — a machine zero and
#  a 30% fraction — turns out to be the two premises of an execution.
#  Class: [T-cited] for the channel coefficients, [A] for the chain.)

## The chain (three steps, no freedom)
1. STATIONARY ROTATION IS AUDIT-DARK (n129 J1, machine zero,
   structural). The audit cannot produce frame dragging. Ever.
2. LARES-2 + LAGEOS (Nature 2026) measure frame dragging = GR to
   one part in a thousand. Somebody in this framework must pay
   that bill.
3. THE CANDIDATE CHANNELS, EACH WITH ITS COEFFICIENT (standard
   linearized results, cited):
      audit response ........... 0    of GR   -> DEAD (1000x error bar)
      scalar budget flow ....... 0    of GR   -> DEAD (1000x error bar)
      vector current channel ... 1/4  of GR   -> DEAD (750x error bar)
      composite spin-2 ......... 1    of GR   -> the only survivor
   Second blade on the vector: spin-1 exchange REPELS like charges —
   a vector gravity channel anti-gravitates; it was dead in statics
   before LARES-2 shot it in dynamics.

## HEADSTONE 31 — the flow reading of frame dragging
n129 proposed g_0i = -v_i (the maintenance flow dragging the metric,
acoustic channel). Buried within a day: any spin-0 or spin-1 carrier
of g_0i is excluded by LARES-2 at hundreds of error bars. Cause of
death: the factor 4. The advection reading survives only as a
DESCRIPTION of the spin-2 composite's effect, never as its carrier.

## What the survivor means (the spectacular part, stated plainly)
The framework's gravitons were located yesterday in the correlation
bilinears (n129 J2: ~30% TT weight, lightlike edge). Today the data
made that location COMPULSORY: a real 2026 satellite measurement,
at one part in a thousand, eliminates every alternative the
framework could have offered. THE RANK-2, SPIN-2 CHARACTER OF
EMERGENT GRAVITY IS NOW FORCED BY OBSERVATION FROM INSIDE THE
THEORY — not assumed to imitate Einstein, but demanded by a
satellite. Einstein put spin-2 in by hand (the metric IS rank 2 in
GR's axioms); here the audit was offered three cheaper options and
the sky refused all three.

## What it costs (carried openly)
The junction's remaining calculation sharpens and hardens: the
TT-bilinear channel must now deliver BOTH the quadrupole formula
(1.3e-4) AND the full factor-4 gravitomagnetic coupling (1e-3) —
there is no fallback channel left. One calculation, two executioners
already in print, no retreat. That is what the framework's own
discipline demands after tonight: the composite graviton either
computes or the theory dies at LARES-2's precision.
