6 new level:'intermediate' progressions (tritone sub, rhythm-changes bridge, gospel passing-dim walk-up, tonicized amen w/ borrowed iv, Just-the-Two-of-Us loop, Sir Duke chromatic vi) x 2 guitar plays each; all progressions in the three styles now carry explicit level. KB: 56 progressions / 112 plays. Critic returned once (3 caption theory misstatements), fixed, PASS on re-gate (voice-leading arithmetic hand-verified from shape constants).
