0^♯ from the full-forcing Σ_n axiom at ω1
Ascertain whether the Σ_n-correct forcing axiom for the class of all forcing with bound ω1, namely Σ_n–CFA_{<ω1}(all), implies the existence of 0^♯.

However, even the answer to the following question is unclear. Does $\Sigma_n\mhyphen CFA_{<\omega_1}(all)$ imply that $0\sharp$ exists?
