Later checked problem lists continue to ask for the missing comparison, but the audit did not locate a definitive current survey. Exact unresolved remainder: Prove both relative-consistency directions between \\(\\mathsf{ZFC}\\) plus projective Ramsey regularity and a precisely stated standard large-cardinal theory, thereby fixing the exact consistency strength. For the named subquestion, prove equiconsistency with one inaccessible cardinal or give strictly sharper matching upper and lower bounds that refute that calibration.",
