Lean foundations

Standard foundations used by the proof

Lean reports the logical foundations below through Mathlib. They are standard proof-system foundations, not conjectural mathematical assumptions about this theorem. The recorded closure stays within the approved classical_mathlib_standard profile, with no unexpected axiom or unfinished-proof placeholder.

Review bindings

Publication reviews accepted

All four required publication-review gates are accepted for the retained presentation of this exact theorem. The review bindings are recorded separately from the Lean build and do not broaden the formal statement.
