nx_coach_markers.nx -- "MAKE THE DATA ACTIONABLE": the wire from the clip-analysis marker library (NXMK) + pose posture into SFW COACHING signals the nishi coach serves. It does NOT re-derive the markers (DRY: it composes ts_classify from nx_ts_marks for the content label + ms profile) -- it adds the ACTIONABLE layer the coach needs: how many dead-air segments to TRIM (and exactly which spans), how many high-energy phrases to PRACTICE, whether cadence (dance rhythm) is present, and a single coaching FOCUS in which an inverted body posture escalates to form/safety. Pure, deterministic, gate-able; the human-readable message table stays in the coach (data-driven), this returns the numeric signals. license_tier: ORIGINAL
