about

nx_skill_coach_audio.nx -- SKILL-COACH (singing/instrument) audio vertical, rung R1: the COACH LOOP that turns a detected pitch into ACTIONABLE FEEDBACK (the operator's ask: "feedback on what exercises/training to get skills up"). Verify-don't-rebuild: the hard PERCEPTION already exists + is gated (nx_pitch YIN-F0 -> PCM, nx_note 12-TET cents); this composes nx_note into GRADE -> DIAGNOSE -> recommend a DRILL. The shared coach ENGINE + rubric-store + gamification + /coach publish are the team-build spec (knowledge/specs, routed to the team). NO floats. Self-gate: 5 known pitches vs target A4 -> correct verdict + drill. license_tier: ORIGINAL
