Giddings–Mangano rebuttal
The argument
Because linked claim, any black hole dangerous in the metastable scenario would also have observable or destructive effects in white dwarfs and neutron stars, so stellar survival does exclude it; and because linked claim, the scenario said to evade the bounds is not physically coherent in the first place.
Does it work?

Premises
- SupportedThe evidence favors the claim, but the examination is incomplete or the evidence is indirect.constitution →Black holes capable of Eddington-limited accretion and radiation are also subject to astrophysical retention bounds.
- SupportedThe evidence favors the claim, but the examination is incomplete or the evidence is indirect.constitution →Plaga's metastable black-hole risk scenario applies Hawking-radiation and accretion formulas inconsistently.

The inference goes through: if black holes capable of Eddington-limited accretion are also subject to retention bounds, then the scenario said to escape stellar-survival constraints is in fact caught by them, and the internal inconsistency in Plaga's use of the radiation and accretion formulas independently undercuts the scenario the bounds are said to miss. Both premises are supported, the first strongly, so the rebuttal presently stands. It would weaken only if a refereed analysis vindicated Plaga's application of the Casadio-Harms model or showed the retention bounds fail in the size regime his rejoinder raises.
