Guide-tone/tritone dyad system with the parallel half- and whole-step laws, 7#9 as the codified blue note, the bVI7->V7 five-voice plane, VI7b9 turnaround hinge, RH sixths; solo two-fisted vs rootless-band contrasts per play. KB now 164 plays. Critic returned once (turnaround jump-kicks bars 3-4 dyad orientations flipped + 2 prose rewordings), fixed, PASS on scoped re-gate (stepwise lap chain recomputed from scratch; "only leap" now provably unavoidable, not just chosen).
