#74 (22 Teilnehmer) ergab automatisch 44 Sprecher, dieselbe Stimme mehrfach. Ursache gemessen: ein Zentroid pro sherpa-Cluster aus max. 3 Schnitten, fester Kosinus auf rohen Embeddings (Kreuz-Turn-Kosinus ~0,4 = keine Trennschaerfe). v2: sherpa liefert nur Turn-Grenzen, Identitaet aus 3-s-Fenster-Embeddings, Mittelwert-Zentrierung, Average-Linkage-AHC, Weak-Fold, Schwelle pro Aufnahme per 2-Gauss-EM gelernt. Validiert: #74 44->20, #70 ->4, #68 ->2. Live-Namensmarker: Namen waehrend der Aufnahme tippen; Zeitstempel benennt spaeter den Cluster und dient als must-/cannot-link-Zwangsbedingung.
