nx_pattern_emit6_log2.nx

nx_pattern_emit6_log2.nx -- PATTERN EMITTER: MATH_KERNEL / LOG2_REDUCE (math-engine repertoire-growth rep -- a NEW emitter-kid past the 9 existing pe6 templates). PROVENANCE: template tutor-SUBMITTED (Claude) for COUNCIL approval; author=TUTOR pending EoE back-fill. The KERNEL it begets is BUILDER/emitter-authored + RECONSTRUCTABLE (re-beget => byte-identical). It REUSES the SOVEREIGN _pm_log_spec (oracle-generated, mpmath@60dps) verbatim -- ZERO new/hand-typed constants. Clones pe6_author_logf64's LOG_REDUCE reduction+poly and changes ONLY the final recombine: log2(x) = log2(2^k * m) = k + ln(m)/ln2 (ln2 reconstructed from spec c[2]+c[3]). LAWS: flat ifs, no &&/||, <=6 args per func, one transcendental per emitted file. license_tier: ORIGINAL
