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
H-29 predicts that (meta)stable negative strangelets produced at rest in interstellar cosmic-ray collisions — where no stopping is needed, closing the lunar bound’s rapidity loophole — would be swept into forming stars and trigger runaway conversion, appearing as anomalous supernova-like events well above the observed rate; the stellar population persisting for gigayears with all large-scale phenomena conventionally accounted for is then improbable to the degree such production ever occurred. H-40 predicts persistence unconditionally: a seeded star just carries an inert strangelet. Direction: toward H-40; the metastability window (decay in space, stability after stopping) is the escape the attached arguments price, not the observation.
Likelihood
# E-32 (HC-8) — lone edge, one observation O-22 "Earth, Sun, white dwarfs, neutron stars and the stars at
# large persist after Gyr of cosmic-ray bombardment". Members in HC-8.hypotheses order [H-29 runaway,
# H-40 no-runaway], no residual. Conditioning as in E-30. Its distinctive discrimination for HC-8:
# interstellar cosmic-ray collisions produce strangelets AT REST (no stopping needed), closing the lunar
# bound's rapidity loophole; under H-29 such strangelets swept into forming stars trigger runaway
# conversion -> anomalous supernova-like events above the observed rate. Anchor H-40 = 1 (rule 7).
lik_stars_H40 = 1.0 # anchor: under no-runaway a seeded star just carries an inert strangelet and
# persists — the stellar population is observed with certainty
lik_stars_H29 = 0.1 # 0.10x, the STRONGEST decrement of the three: A-33 (approved) makes the bound
# velocity-assumption-free (production at rest in space), and A-60 (approved) prices
# the supernova-rate bound at 2e-8, tightening to ~1e-21 with Fe/AGS physics. Its sole
# escape is metastability (decay between ~1e-7 s and the Myr of star formation) — a
# loophole DISJOINT from E-30's rapidity loophole, so this edge's own increment is
# closing the rapidity escape, legitimately multiplied against E-30 rather than
# re-counting the shared chain. (WD/NS args A-29/A-30 concern black holes, not the
# strangelet cluster — excluded here.)
t_stars = 0.82 # cap = trust_score(O-22 source S-1) = 0.82; stellar / Sun / WD / NS persistence is an
# uncontested background fact with no selection/dating weakness — held at the cap
