 ## Kernregeln
 
-- **Options-Schema lebt im Code**, nicht in der DB (`getOptions()` je Modul). In der DB stehen nur die Werte.
-  Optionsform: `['name', 'label', 'type', 'required']`. `type` ist i.d.R. `'string'`; `'richtext'` wird im Frontend über
-  `Views/Components/TextEditor.vue` (TinyMCE, HTML) gerendert und via `v-html`/`{!! !!}` ausgegeben.
+- **Zwei getrennte Options-Schemata (beide im Code, gleiche Form `['name','label','type','required']`):**
+    - `getOptions()` = **Admin-Config** (was der/die Veranstalter\*in pflegt, z.B. Empfänger-Konto). Werte in der DB
+      (`configuration`, s.u.).
+    - `getParticipantOptions()` = **Teilnehmer-Eingaben** beim Anmelden (payer-seitig, z.B. künftig
+      SEPA-IBAN/PayPal-Mail; beide Bestandsmodule: `[]`). Werte in `event_participants.payment_options` (JSON).
+      Abgesichert über
+      `sanitizeParticipantOptions()` / `participantOptionsComplete()` (Guard im `SignUpCommand`).
+    - `type` ist i.d.R. `'string'`; `'richtext'` wird über `Views/Components/TextEditor.vue` (TinyMCE, HTML) gerendert
+      und via `v-html`/`{!! !!}` ausgegeben; `'icon'` rendert die `Views/Components/RichSelectBox.vue` (kuratierte
+      FA-Symbol-Auswahl, Liste in `resources/js/constants/paymentMethodIcons.js`). Teilnehmer-Eingaben rendert die
+      generische `SignUpForm/components/PaymentMethodInputs.vue` schema-getrieben.
+  - Optionaler Schlüssel `'hint'` je Option: erklärender Hilfetext, den die Admin-Render-Stellen unter dem Feld anzeigen
+    (z.B. bei `payment_information`, dass der Text am Anmeldeende + in der Mail erscheint).
+  - `defaultConfiguration()` je Modul liefert die Start-Config beim Anlegen der Tenant-Instanz (`CreateTenantAction`),
+    aktuell das Default-Symbol (`icon`): Überweisung `building-columns`, Sonstiges `coins`.
 - **Aktivierungs-Guard:** Eine Tenant-Zahlungsmethode darf nur `active` werden, wenn alle `required`-Optionen befüllt
   sind (`isConfigurationComplete()`), erzwungen in `UpdateAvailablePaymentMethodAction`.
 - **Config-Speicherung (JSON):** pro Tenant auf `available_payment_methods.configuration`, pro Event auf dem Pivot
   `event_payment_methods.configuration`. Beim Zuweisen an ein Event wird die Tenant-Config als **Snapshot kopiert**
-  (Copy-on-Assign, spätere Tenant-Änderungen wirken NICHT nach). Sync erfolgt differenziell in `UpdateEventCommand`.
-- **`PaymentMethod` ist nur eine Fassade:** `PaymentMethod::optionsFor/requiredOptionKeys/sanitizeConfiguration/`
-  `isConfigurationComplete/defaults()` delegieren an die Registry. Bestehende Aufrufstellen bleiben so stabil.

+  Zusammenfassung ist eine Admin-Config-Option `summary_confirmation_text` (`{amount}`-Platzhalter) und erscheint nur
+  bei
+  `PAYMENT_ACCOUNT_TRANSACTION`.
 - **`PaymentStatus`** ist ein DB-gestütztes Enumerations-Model (`app/Enumerations/PaymentStatus.php`, Tabelle
   `payment_status`, geseedet in `ProductionDataSeeder`), analog zu `InvoiceStatus`. Reine Steuersignale (z.B. Redirect)
