pub const LOG2_E: u64 = 94_549;Expand description
log2(e) in fixed point, rounded up.
Appears in the random-words cutoff of 2025/2010 section
1.5, in bits_per_query’s numerator, whose ceil_log2 is then subtracted from the
uncorrected rate. Rounding this constant down would shrink that correction and overstate the
reported per-query rate, contradicting this module’s conservative-lower-bound invariant.
