- ProofPdfService: Veroeffentlichungsnachweis 3 Credits pauschal, einmal pro
PM (Zweitdownload kostenfrei); ProofPdfRenderer erzeugt das PDF on-demand
aus vorhandenen PM-Daten (kein externer Renderer); GET-Download-Endpoint
/admin/me/press-releases/{id}/nachweis hinter downloadProof-Policy + Kauf-Gate
- ExtraPmPurchaseService: tier-gestaffelter Nachkauf (19/15/12/10/8) aus der
Wallet; verbucht als bezahlter SinglePurchase(ExtraPm) und greift damit in
die bestehende Kontingent-/Slot-Mechanik. InsufficientCreditsException
liefert das Mini-Checkout-Signal (required/available/shortfall)
