ModularDiscriminantBridge

formal source

 109    The Dedekind eta function η(τ) = q^{1/24} ∏ₙ (1 − qⁿ) counts
 110    the microstates of a single mode; raising to the 24th power counts
 111    all 24 directed flux modes on the voxel. -/

 125    The Leech lattice Λ₂₄ is the unique even unimodular lattice in
 126    dimension 24 with no vectors of norm 2. Its uniqueness properties
 127    mirror the uniqueness of the Q₃ double-entry structure. -/

 134/-! ## §4. Why String Theory's Interpretation Is Wrong -/
 135
 136/-- String theory claims D_crit = 26 = 24 + 2 (transverse + longitudinal).
 137    RS claims D = 3 and 24 = directed flux on Q₃.
 138
 139    The mathematical content (the number 24 and its role in partition
 140    functions) is identical. The physical interpretation differs:
 141    - String theory: 24 transverse spatial dimensions
 142    - RS: 24 directed flux modes on the Q₃ double-entry ledger
