Reasoning
A charged TeV-scale black hole loses energy by ionization like a heavy charged particle; the stopping length in rock or solar plasma is short, so cosmic-ray-produced charged black holes would have accumulated inside Earth and the Sun over Gyr. Their survival therefore bounds this branch directly. Consequently the only branch needing the white-dwarf/neutron-star argument is the doubly-hypothetical one: Hawking radiation fails AND the black hole sheds all charge (Schwinger discharge), making it neutral and penetrating. This narrows what the overall safety verdict hinges on.
Original
“If stable black holes retain electric charge (or otherwise interact electromagnetically), ordinary ionization stopping traps even relativistic cosmic-ray-produced ones inside Earth and the Sun, so 4.5 Gyr of survival under the measured cosmic-ray flux directly excludes danger without any white-dwarf step.”
Verdict (step 6)
corrected / checked. The trapping step is valid: conditional on charge retention, ionization stopping of a heavy charged particle in rock/plasma is short-range, so Gyr accumulation inside Earth and Sun follows. But “directly excludes danger” overclaims: an undercutting defeater survives — observer selection (A-6 - Observer selection makes naive survival-based risk bounds uninformative): Earth/Sun survival is conditioned on our existence, so P(we observe survival | dangerous) is not straightforwardly small. The weaker evidential form (“direct evidence against danger for this branch, subject to observer-selection correction”) is immune to the defeater and preserved; the branch-narrowing corollary (only the neutral, Schwinger-discharged branch needs the WD/NS argument) stands unchanged. Statement edited accordingly; filename left as-is per spec.
