 ### BL-05 — Budget: Wiederkehrende Buchungen automatisch generieren
 
-**Status:** Offen
+**Status:** Erledigt (v0.3.0)
 **Aufwand:** S (1–2 Tage)
 
 Das Budget-Formular hat eine „Wiederkehrend"-Checkbox und speichert `is_recurring = 1`. Es fehlt jedoch die automatische Generierung der Folgebuchungen. Derzeit muss der Nutzer jede Buchung manuell eintragen.

 ### Added
+- Budget: recurring entries auto-generate instances for each viewed month; instances deleted by the user are skipped permanently via `budget_recurrence_skipped` table; generated instances are marked with ↩ in the transaction list
 - Budget: month-over-month comparison in summary cards — each card (Einnahmen, Ausgaben, Saldo) shows a trend line (▲/▼ + delta amount vs. previous month); previous month summary is fetched in parallel with current month
