 6. Jede erfasste Auszahlung aus dem Mining-Tool muss den Walletbestand automatisch fortschreiben. Externe Auszahlungen aus dem hier verfolgten Wallet reduzieren ihn.
 7. Der angezeigte bisherige Wert trennt variable Werte (Coins im Mining-Tool und Wallet zum aktuellen Kurs) von fixen Werten (bereits mit Krypto bezahlte Miner zum Ausgabezeitpunkt). Die Gesamtsumme besteht aus beiden Kategorien.
 8. Jede neue feste Krypto-Buchung referenziert die `fetch_id` des Moduls `fx-rates`. Der Mining-Checker fuehrt keine eigene Kurstabelle. Umrechnungen in andere Berichtswährungen verwenden fuer fixe Werte denselben historischen API-Snapshot.
+9. Wird ein gemieteter Miner geloescht, wird sein kompletter Datensatz entfernt: Mietkosten, feste Krypto-Bewertung, FX-Referenz und der daraus abgeleitete Wallet-Abzug entfallen. Der Miner beeinflusst danach weder Walletbestand noch Ausgaben, Reinvest, Hashrate oder Break-even. Basis-Angebote, Mining-Uploads und andere Wallet-Buchungen bleiben unveraendert.
