O-22 - Earth, Sun, white dwarfs, neutron stars and the stars at large have survived billions of years of cosmic-ray bombardment
This is the survival half of the cosmic-ray safety argument: the exposure count is a measurement (see the flux observation), while this node records the uncontested background fact that the exposed bodies persist. The white-dwarf and neutron-star part carries the load for the hypothetical stable-neutral-black-hole case: their large observed populations at Gyr ages are what the Giddings-Mangano accretion argument turns on, since dense stars stop even neutral black holes and would be destroyed on short timescales, ending in highly visible explosive events that are not observed.

Why this is evidence
The survival half of the cosmic-ray argument as it bears on the trapped-hole fate: if stable holes with H-8-style dangerous accretion were produced by cosmic rays and stopped in dense stars, the exposed populations would show destroyed stars or astrophysical black holes that conventional astrophysics cannot account for — neither is observed. H-22 predicts exactly this quiet sky; H-8 and sub-solar-lifetime H-36 variants make it improbable. The extra content beyond the specific compact-star observations is the absence of any anomalous or unexplained black-hole population among the exposed stars.
Likelihood
# E-42 (HC-4) — lone edge, one observation O-22 "exposed astronomical bodies persist with no anomalies".
# Members in HC-4.hypotheses order [H-8 catastrophic, H-22 negligible, H-36 residual]. Broad LSAG survival
# statement whose discriminating content here is the compact-star survival PLUS the absence of any anomalous
# black-hole population conventional astrophysics cannot explain. The compact-star / population content
# escapes the anthropic shadow (A-30, approved: neutral holes would destroy observed WD/NS; A-29, approved:
# charged holes accumulate in Earth/Sun), but the observation also bundles the shadow-contaminated Earth/Sun
# survival, and is qualitative where E-39 is a specific quantitative WD bound — so a shade weaker than E-39.
# Anchor H-22 = 1 (rule 7).
lik_cr_H22 = 1.0 # anchor: negligible growth predicts exactly this quiet sky — surviving stars, no
# unexplained black-hole population
lik_cr_H8 = 0.15 # 0.15x as expected as under H-22: cosmic-ray-produced dangerous stable holes would have
# left destroyed dense stars or an anomalous BH population (A-29/A-30, approved); their
# absence is improbable under catastrophic accretion. Slightly above E-39's 0.1 because the
# statement is broad/qualitative and its Earth-Sun component is shadow-softened, so it
# discriminates a touch less sharply than the direct WD bound
lik_cr_H36 = 0.55 # 0.55x: an intermediate regime could evade the highly-visible-destruction signature while
# still being dangerous on long timescales; unconstrained, middling (rule 3)
t_cr = 0.68 # cap = trust_score of O-22's source S-1 (LSAG) = 0.82. Docked more than E-39: this is a
# qualitative review-level summary that bundles the anthropic-contaminated Earth/Sun
# survival with the clean compact-star/population content, so the raw-data-to-observation
# step is looser
