+Triage-Helfer: Beantwortet die Gegenfragen der Züchterin zu RPRO3-Namensdubletten.
+
+Liefert pro Variante (A/B/C … exakt wie im Rückfrage-Ticket) die Daten, die die
+Züchterin typischerweise sehen will: Geburtsdatum, Farbe, **Gencode (Fcode)**,
+Herkunft, Eltern (Vater/Mutter) sowie Nachzucht inkl. Co-Elternteil (Partner).
+
+Die Variantenbildung/Label-Vergabe spiegelt rpro3_tickets.py + compare_rpro3.dedup
+exakt (Union-Find über gleiche Namen; Filter „informativ"; Sortierung
+(not is_own, -count) → A,B,C…). Im Gegensatz zum Ticket wird hier über den GESAMTEN
+Cluster aggregiert (rpro3_tickets kappt rids auf 4 – Nachzucht wäre sonst unvollständig).
+

+      LETTERS optional, z. B. "B,C" → nur diese Varianten. Default: alle.
