+# Market Management
+
+Stand: 2026-09-15
+Status: Fachliches Zielbild / Anforderungen in Ausarbeitung
+
+## Zweck
+
+Das Modul verwaltet Märkte von der Recherche und Prüfung über Anfrage, Anmeldung
+und Durchführung bis zur Kosten-, Zahlungs- und Erlösauswertung.
+
+## Fachliche Ownership
+
+Das Modul soll die fachliche Ownership für Marktstammdaten, Markttermine,
+Teilnahme- und Durchführungsstatus, marktbezogene Kosten und Zahlungen sowie
+Erlös- und Tagesauswertungen tragen.
+
+## Zugriffsmodell
+
+Die Nutzung des Moduls ist an eine Benutzeridentität gebunden. Das Modul soll
+separat von der übrigen Anwendung nutzbar und an weitere Personen verkaufbar
+sein.
+
+Die Ownership der Lizenz-/Entitlement-Daten ist noch nicht entschieden und
+bleibt offen.
+
+## MCP-Schnittstelle zu Hermes
+
+Die App stellt die MCP-Server-Schnittstelle bereit. Hermes Agent ist MCP-Client
+und ruft ausschließlich freigegebene Funktionen des Marktmanagement-Moduls
+auf.
+
+Die App behält die Kontrolle über:
+
+- Authentifizierung und Berechtigungsprüfung
+- Validierung und fachliche Interpretation der Eingaben
+- erlaubte Schreiboperationen
+- Persistierung in der eigenen Datenbank
+- Audit- und Quelleninformationen
+
+Hermes erhält keinen direkten Zugriff auf die Datenbank. Das Zielbild und die
+Schnittstellenentscheidungen sind im
+[market_management_hermes_mcp_konzept.md](konzepte/market_management_hermes_mcp_konzept.md)
+dokumentiert.
+
+## Abgrenzung
+
+- Zunächst keine eigene Benutzerverwaltung.
+- Keine eigene technische Runtime- oder Scheduler-Logik.
+- Fachlich neutrale UI- und technische Querschnittsbausteine gehören nach
+  `shared`.
+
+## Dokumente
+
+- [Anforderungsprofil](requirements/market_management_requirements.md)
+- [Datenarchitektur](data/market_management_data_architecture.md)
+- [Technisches Tabellen- und Prozesskonzept](konzepte/market_management_technisches_konzept.md)
+- [Hermes-MCP-Konzept](konzepte/market_management_hermes_mcp_konzept.md)
+- [DB-Ownership-Konzept](konzepte/market_management_db_ownership.md)
+- Prozessdokumente werden unter `processes/main/` und
+  `processes/sub_processes/` angelegt, sobald die fachlichen Prozesse explizit
+  definiert sind.
+
+## Offene Architekturentscheidung
+
+Die Ownership und konkrete Ablage der Lizenz-/Entitlement-Daten ist offen.
+Diese Entscheidung darf bei der weiteren Umsetzung nicht stillschweigend
+vorweggenommen werden.

+# market_management_data_architecture
+
+Stand: 2026-09-18
+Status: Bestätigtes Datenarchitektur-Zielbild
+
+## 1. Ziel
+
+Das Marktmanagement-Modul muss wiederkehrende Märkte mit mehreren konkreten
+Durchführungen und mehreren Tagen je Durchführung ohne redundante Vermischung
+der Daten abbilden können.
+
+## 2. Bestätigte Hierarchie
+
+```text
+Kategorie 1 ─── n Marktdefinition 1 ─── n Durchführung 1 ─── n Durchführungstag
+```
+
+Eine Kategorie enthält beliebig viele Marktdefinitionen. Jede Marktdefinition
+gehört genau einer Kategorie.
+
+### Kategorie
+
+Eine Kategorie ordnet Märkte fachlich. Fabienne darf die deterministische
+Kategorie-/Marktartliste erweitern. Hermes darf bestehende Kategorien
+verwenden, aber keine Kategorien anlegen.
+
+### Marktdefinition
+
+Eine Marktdefinition ist die übergeordnete fachliche Identität, unter der
+mehrere konkrete Durchführungen geführt werden können. Der zentrale Marktstamm
+enthält nur den eindeutigen Marktnamen und die Marktart/Kategorie.
+
+### Durchführung
+
+Eine Durchführung ist eine konkrete Ausgabe bzw. Teilnahme an einem Markt. Die
+Durchführung kann einen oder mehrere Durchführungstage umfassen.
+
+### Durchführungstag
+
+Ein Durchführungstag ist ein einzelner Tag innerhalb einer konkreten
+Durchführung. Tagesbezogene Zeit-, Erlös- und Verkaufsdaten gehören auf diese
+Ebene.
+
+## 3. Feld- und Referenzwert-Zuordnung
+
+### Zentraler Marktstamm
+
+- Marktname
+- Marktart/Kategorie aus einer deterministischen Liste
+- optionale Website-URL der Veranstaltung
+
+### Durchführung
+
+Alle übrigen veränderlichen Marktangaben werden pro Durchführung erfasst,

+## 2. Fremde Datenreferenzen
+
+### Kontaktmodul
+
+Das Marktmanagement-Modul speichert nur die stabilen IDs von Organisation und
+Kontaktperson. Es schreibt keine Kontakt-, Organisations- oder Adressdaten in
+fremde Tabellen.
+
+### OTC-/Direktverkaufsmodul
+
+Das OTC-Modul bleibt Owner seiner Verkaufstabellen. Jeder neue OTC-Verkauf
+referenziert einen gültigen `market_occurrence_day_id`. Marktmanagement liest
+die Verkaufsdaten ausschließlich über die definierte Schnittstelle für die
+Umsatz- und Artikelmengenaggregation.
+
+## 3. Schreibgrenzen
+
+- Direkte Cross-Modul-Writes sind verboten.
+- Marktmanagement schreibt nicht in OTC-, Kontakt- oder Organisations-Tabellen.
+- Das OTC-Modul schreibt nicht in Marktmanagement-Tabellen.
+- MCP schreibt nie direkt in Tabellen.
+- Alle Marktmanagement-Writes laufen über den owning Modul-Service.
+
+## 4. Referenzdaten
+
+Der Gemeindereferenzbestand verwendet die BFS-Gemeindenummer als stabile
+fachliche Referenz und speichert den Datenstand zur Nachvollziehbarkeit.
+
+Die Kategorie-/Marktartliste gehört zum Marktmanagement und wird durch Fabienne
+gepflegt. Hermes darf sie nur lesen.
+
+## 5. Technische Änderungsregeln
+
+- Tabellen- und Constraint-Änderungen erfolgen ausschließlich über versionierte
+  Migrationen.
+- Fachliche Constraints werden im DB- und Prozessvertrag gespiegelt.
+- Aggregierte Umsatzwerte werden nicht als unabhängige Fachwahrheit gespeichert.
+- Archivierte Datensätze bleiben erhalten.
+- Markt und Durchführung besitzen getrennte Archivstatus.

+
+## Fachliche Grenzen
+
+- Hermes erhält keinen direkten Datenbankzugriff.
+- Hermes darf keine Kategorien anlegen.
+- Umsatz und Artikelmengen werden nicht über MCP geschrieben; sie werden aus
+  den OTC-Verkäufen abgeleitet.
+- Markt und Durchführung werden unabhängig archiviert.
+- Alle Schreibvorgänge werden serverseitig validiert.
+- Jeder schreibende MCP-Aufruf benötigt `idempotency_key`; optional kann
+  `client_id` mitgegeben werden. Wiederholungen liefern dasselbe Ergebnis.
+- Umsatz- und Artikelmengen aus OTC-Verkäufen sind erst verfügbar, sobald die
+  separate OTC-Schnittstelle die Zuordnung zum Durchführungstag bereitstellt.
+
+## Fehler
+
+Bei fehlender oder ungültiger Authentifizierung antwortet der Endpunkt mit
+HTTP 401. Ungültige JSON-RPC-Requests oder fachlich ungültige Eingaben werden
+als JSON-RPC-Fehlerantwort zurückgegeben.

+# Market Management: Hermes-MCP-Konzept
+
+Stand: 2026-09-19
+Status: Verbindliches Schnittstellenkonzept
+
+## 1. Zweck
+
+Die App stellt einen geschützten MCP-Server bereit. Hermes Agent ist MCP-Client
+und arbeitet im Benutzerkontext. Hermes kann Marktmanagement-Daten suchen,
+anlegen, ändern, archivieren und reaktivieren.
+
+## 2. Verantwortungen
+
+Die App kontrolliert:
+
+- Authentifizierung
+- Benutzer- und Modulberechtigung
+- Eingabevalidierung
+- fachliche Feldzuordnung
+- Persistierung
+- Audit- und Herkunftsdaten
+- Idempotenz
+
+Hermes besitzt keinen direkten Zugriff auf Datenbank, interne Services oder
+fremde Module.
+
+## 3. Schnittstellenmodell
+
+Der MCP-Server veröffentlicht fachliche Tools, keine generischen Datenbank-
+oder Tabellenoperationen.
+
+Vorgesehene Toolgruppen:
+
+- Märkte suchen und lesen
+- Märkte anlegen, ändern, archivieren und reaktivieren
+- Durchführungen suchen und lesen
+- Durchführungen anlegen, ändern, archivieren und reaktivieren
+- Durchführungstage anlegen, ändern und entfernen
+- Kategorien, Kantone und Gemeinden lesen
+- Kosten und Zahlungsstatus ändern
+- Übersichtsdaten lesen
+
+Hermes darf bestehende Kategorien verwenden, aber keine Kategorien anlegen.
+Umsatz- und Artikelmengen werden nicht über Hermes geschrieben, sondern aus den
+OTC-Verkäufen abgeleitet.
+
+## 4. Authentifizierung und Autorisierung
+
+- MCP-Endpunkt über geschütztes HTTPS
+- Bearer-Token-Prüfung an der Transportgrenze
+- der konfigurierte Token identifiziert den technischen Hermes-Benutzerkontext
+- zusätzliche Prüfung im jeweiligen Tool-Handler
+- kein direkter Datenbankzugriff für Hermes
+
+Für die erste Implementierungsstufe wird bewusst keine neue OAuth-/OIDC- oder
+Entitlement-Infrastruktur eingeführt. Der Token wird ausschließlich über die
+geschützte App-Konfiguration bereitgestellt und mit konstanter Zeit verglichen.
+Die Implementierung verwendet dafür den Konfigurationswert
+`MARKET_MCP_TOKEN`.
+
+Die fachliche Ownership der Lizenz-/Entitlement-Daten bleibt offen. Die
+Schnittstelle prüft nur die über den bestehenden Zugriffskontext gelieferte
+Modulberechtigung.
+
+## 5. Schreibregeln
+
+- Jeder Tool-Aufruf ist atomar.
+- Fehlgeschlagene Aufrufe erzeugen keine Teilpersistierung.
+- Alle Schreibvorgänge laufen über die interne Modul-API.
+- Hermes darf bei einem neuen Markt nur eine bestehende Kategorie referenzieren.
+- Dokumentlinks können optional als Herkunftsinformation mitgegeben werden.
+- Unsichere Erkennung wird nicht durch eine zusätzliche App-Freigabelogik
+  behandelt; die fachliche Qualitätssicherung liegt im Hermes-Training.
+
+## 6. Wiederholungsschutz
+
+Schreibende Aufrufe können eine Idempotenzreferenz übergeben. Die App speichert
+Client, Benutzer, Tool, Schlüssel, Request-Hash und Verarbeitungsergebnis in
+`market_mcp_idempotency`.
+
+Ein wiederholter Aufruf mit gleichem Schlüssel und gleichem Request liefert das
+bereits bekannte Ergebnis. Ein gleicher Schlüssel mit verändertem Request wird
+abgewiesen.
+
+## 7. Daten- und Modulgrenzen
+
+- Marktmanagement schreibt nur in eigene Tabellen.
+- Das OTC-Modul schreibt die Verkaufstabelle und referenziert den
+  `market_occurrence_day_id`.
+- Kontakt- und Organisationsdaten werden über das Kontaktmodul referenziert.
+- Gemeindedaten werden über den eigenen Referenzbestand gelesen.
+- MCP-Komposition enthält keine Marktfachlogik.

+Datum, Umsatz und Artikelmengen werden daraus ermittelt.
+
+Historische OTC-Verkäufe ohne diese Zuordnung werden nicht migriert.
+
+## 4. Normatives Prozessmodell
+
+Alle fachlichen Prozesse gehören zum owning Modul `market_management`, außer der
+OTC-Verkaufsprozess selbst. Die OTC-Integration erfolgt ausschließlich über die
+öffentliche Marktmanagement-Schnittstelle.
+
+### 4.1 Zentrale Marktdefinition verwalten

+
+Fachliche Aufgabe:
+
+- Kostenpositionen und manuelle Zahlungsinformationen pflegen
+
+Liest:
+
+- Durchführung
+- bestehende Kostenpositionen
+
+Schreibt:
+
+- `market_occurrence_cost_item`
+- Zahlungsfelder in `market_occurrence`
+
+### 4.5 OTC-Verkauf einem Durchführungstag zuordnen
+
+Fachliche Aufgabe:

+
+Liest:
+
+- verfügbare Märkte, Durchführungen und Durchführungstage über die
+  Marktmanagement-Schnittstelle
+
+Schreibt:
+
+- ausschließlich das OTC-Modul in seine eigene Verkaufstabelle
+
+### 4.6 Umsatz- und Artikelmengen lesen

+- OTC-Aggregate
+
+Schreibt:
+
+- nichts
+
+### 4.8 Hermes-MCP-Zugriff
+
+Fachliche Aufgabe:
+
+- Hermes über die kontrollierte MCP-Schnittstelle suchen, anlegen, ändern,
+  archivieren und reaktivieren lassen
+
+Liest:
+
+- Marktmanagement-Daten und erlaubte Referenzdaten
+
+Schreibt:
+
+- ausschließlich über die internen Marktmanagement-Services
+- `market_mcp_idempotency` für Wiederholungsschutz
+
+Die konkrete MCP-Schnittstelle ist in
+[market_management_hermes_mcp_konzept.md](market_management_hermes_mcp_konzept.md)
+dokumentiert.
+
+## 5. Normative Betriebsregeln
+
+- Marktname und Kategorie sind zentrale Stammdaten.
+- Alle variablen Veranstaltungsdaten werden je Durchführung gepflegt.
+- Tageswerte werden je Durchführungstag gepflegt.
+- Wochentag, Saison, Datumsbereich, Gesamtkosten, offener Betrag, Umsatz und
+  Artikelmengen werden abgeleitet.
+- Umsatz und Artikelmengen stammen ausschließlich aus OTC-Verkäufen.
+- Stornos und Rückerstattungen werden in den Aggregaten abgezogen.
+- Markt- und Durchführungarchivierung sind unabhängig.
+- Der erste Status ist `offen`.
+- `durchgefuehrt` wird nach dem letzten Durchführungstag automatisch gesetzt,
+  sofern die Durchführung nicht `abgesagt` ist.
+- Die GUI enthält keine fachliche Primärlogik.
+- Hermes erhält keinen direkten DB-Zugriff.
+- Punkt 11 und folgende sind nicht Teil dieses Zielbilds.
+
+## 6. Ausgabevertrag
+
+Das Modul liefert:
+
+- eindeutige Markt-, Durchführungs- und Tagesidentitäten
+- validierte Stammdaten und Referenzen
+- unabhängigen Markt- und Zahlungsstatus
+- berechnete Kosten-, Umsatz- und Artikelmengenwerte
+- serverseitig filter- und sortierbare Übersichtsdaten
+- kontrollierte MCP-Ergebnisse für Hermes
+
+## 7. Erfolgskriterien
+
+- Marktdefinitionen sind eindeutig und genau einer Kategorie zugeordnet.
+- Durchführungen und Durchführungstage sind unabhängig und vollständig
+  verwaltbar.
+- Jeder neue OTC-Verkauf ist genau einem Durchführungstag zugeordnet.
+- Umsatz und Artikelmengen werden nicht manuell doppelt erfasst.
+- Kontakt- und Gemeindedaten werden über definierte Referenzen verwendet.
+- Archivierung funktioniert getrennt für Markt und Durchführung.
+- MCP-Schreibvorgänge sind authentifiziert, berechtigt und idempotent.
+- Die fachliche Logik bleibt im owning Modul.
+

+# Anforderungsprofil Marktübersicht
+
+Stand: 2026-09-15
+Status: Fachliche Arbeitsanforderung
+
+## 1. Ziel des Systems
+
+Das System unterstützt die Suche, Prüfung, Anmeldung, Durchführung und
+Auswertung von Herbstmärkten, Weihnachtsmärkten und weiteren geeigneten
+Märkten.
+
+## 2. Umfang der ersten Phase
+
+- Es wird jeweils nur ein Markt gleichzeitig bearbeitet.
+- Zunächst gibt es nur eine Benutzerin: Fabienne.
+- Eine eigene Benutzerverwaltung ist zunächst nicht erforderlich.
+- Die Anwendung soll übersichtlich und einfach bedienbar sein.
+
+## 3. Datenhierarchie
+
+Die Daten müssen mehrstufig abbildbar sein:
+
+```text
+Kategorie
+└── Markt
+    └── Durchführung
+        └── Durchführungstag
+```
+
+- Es können beliebig viele Kategorien und Märkte existieren.
+- Ein Markt gehört genau einer Kategorie.
+- Fabienne darf die deterministische Kategorie-/Marktartliste erweitern.
+- Hermes darf bestehende Kategorien auswählen, aber keine Kategorien anlegen.
+- Ein Markt kann beliebig viele Durchführungen enthalten.
+- Eine Durchführung kann beliebig viele Durchführungstage enthalten.
+- Erlös- und Verkaufsdaten werden auf Ebene des Durchführungstags erfasst und
+  auf Ebene der Durchführung sowie des Marktes auswertbar gemacht.
+
+Der zentrale Marktstamm enthält ausschließlich:
+
+- Marktname
+- Marktart/Kategorie aus einer deterministischen Liste
+- optionale Website-URL der Veranstaltung
+
+Alle übrigen veränderlichen Angaben werden pro Durchführung erfasst. Tages-
+und Verkaufsdaten werden pro Durchführungstag erfasst.
+
+## 4. Nutzungsberechtigung
+
+- Die Rechte zur Nutzung des Moduls werden an die Benutzeridentität geknüpft.
+- Das Modul soll ohne die restliche Anwendung an weitere Personen verkauft und
+  separat genutzt werden können.
+- Die Ownership und Ablage der Lizenz-/Entitlement-Daten ist noch nicht
+  entschieden und bleibt offen.
+
+## 5. Marktarten
+
+Initial verfügbare Marktarten:
+
+- Herbstmärkte
+- Weihnachtsmärkte
+- Frühlingsmärkte
+- Ostermärkte
+- Kunsthandwerksmärkte
+- Regionalmärkte
+- Weitere geeignete Märkte
+
+Die Marktart/Kategorie wird zentral am Markt aus einer deterministischen Liste
+ausgewählt. Eine Durchführung überschreibt diese Zuordnung nicht.
+

+
+### 6.1 Allgemeine Informationen
+
+- Veranstalter
+- Ort
+- Gemeinde
+- Kanton
+- Adresse
+- Kontaktperson
+- E-Mail-Adresse

+- Zahlungsfrist
+- Zahlungsart
+- Abmeldebedingungen
+- Umsatzbeteiligung, falls vorhanden
+- Weitere Teilnahmebedingungen
+
+### 6.6 Vertrag und Unterlagen
+
+Die zugehörigen Unterlagen sollen über einen Link mit einem eigenen Ordner
+verbunden werden können.
+
+- Link zum Vertragsordner
+
+Der Link wird pro Durchführung erfasst.
+
+### 6.7 Deterministische Referenzwerte und Berechnungen
+
+Deterministisch vorgegebene Referenzwerte; die jeweilige Auswahl wird auf der
+zuständigen Ebene gespeichert:
+
+- Marktart/Kategorie
+- Marktstatus
+- Zahlungsstatus
+- Zahlungsart
+- Kanton
+- standardisierte Ja/Nein-Merkmale für Infrastrukturangaben
+
+Abgeleitete Werte werden nicht manuell eingegeben:
+
+- Wochentag aus dem Datum
+- Saison aus dem Durchführungsdatum
+- Gesamtkosten aus den Kostenpositionen
+- offener Betrag aus Kosten und bezahltem Betrag
+- Gesamterlös, Durchschnittswerte und Gesamtzahl verkaufter Artikel aus den
+  Durchführungstagen
+
+## 7. Statusverwaltung
+
+Folgende Marktstatus sollen verfügbar sein:
+
+- Offen
+- Warteliste
+- Angemeldet
+- Bestätigung ausstehend
+- Bestätigt
+- Abgesagt
+- Durchgeführt
+
+Der initiale Status ist `Offen`. Die Statuswerte werden grundsätzlich manuell
+gesetzt. `Durchgeführt` wird nach dem letzten Durchführungstag automatisch
+gesetzt, sofern die Durchführung nicht abgesagt ist. Manuelle Korrektur bleibt
+möglich.
+
+## 8. Bezahlung
+
+Der Zahlungsstatus wird unabhängig vom allgemeinen Marktstatus gespeichert.
+
+Zahlungsstatus:
+
+- Nicht bezahlt
+- Bezahlt
+
+Zusätzliche Zahlungsinformationen:
+
+- Zahlungsdatum
+- Bezahlter Betrag
+- Offener Betrag
+
+## 9. Erlöserfassung
+
+Der Erlös wird nicht manuell erfasst, sondern aus den OTC-Verkäufen berechnet.
+Bei mehrtägigen Märkten wird der Erlös je Durchführungstag separat ermittelt.
+
+Pro Durchführungstag:
+
+- Datum
+- Bruttoerlös aus OTC-Verkäufen
+- Anzahl verkaufter Artikel aus OTC-Positionen
+- Besondere Ereignisse oder Beobachtungen
+
+Automatisch zu berechnen:
+
+- Gesamterlös des Marktes
+- Gesamtzahl verkaufter Artikel
+- Durchschnittlicher Erlös pro Tag
+- Durchschnittlicher Erlös pro verkauftem Artikel, sofern berechenbar
+
+Die Tageswerte sollen einzeln und als Gesamtergebnis auswertbar sein.
+
+## 10. Marktübersicht
+
+Die zentrale Übersicht soll ermöglichen:
+
+- alle Märkte anzuzeigen
+- nach Marktart zu filtern
+- nach Status zu filtern
+- nach Gemeinde oder Ort zu filtern
+- nach Datum zu sortieren
+- nach Erlös zu sortieren
+- den Bezahlstatus zu erkennen
+- kommende Märkte hervorzuheben
+- überfällige Anmeldungen oder Zahlungen zu erkennen
+- Märkte zu öffnen und zu bearbeiten
+
+Mindestens sichtbar:
+
+- Marktname
+- Marktart
+- Ort oder Gemeinde
+- Datum
+- Wochentag
+- Status
+- Gesamtkosten
+- Bezahlstatus
+- Bruttoerlös
+
+## 11. Intelligente Auswertungen
+
+Das System soll später Zusammenhänge, Unterschiede und mögliche Korrelationen
+zwischen Marktmerkmalen und Ergebnissen sichtbar machen.
+
+### 10.1 Marktart und Erlös
+
+- Welche Marktarten erzielen den höchsten Erlös?
+- Sind Weihnachtsmärkte erfolgreicher als Herbstmärkte?
+- Welche Marktarten haben das beste Verhältnis zwischen Erlös und Kosten?
+- Welche Marktarten führen zu den meisten verkauften Artikeln?
+
+### 10.2 Datum, Saison und Erlös
+
+- An welchen Daten werden die höchsten Erlöse erzielt?
+- Gibt es Unterschiede zwischen frühem und spätem Saisonzeitpunkt?
+- Wie entwickelt sich der Erlös innerhalb einer Saison?
+- Welche Monate und Jahreszeiten sind besonders erfolgreich?
+- Gibt es einen Zusammenhang zwischen Marktdatum und Verkaufsleistung?
+
+### 10.3 Zahlungstermin und Markterfolg
+
+- Wie viele Tage liegen zwischen Zahlungstermin und Marktdatum?
+- Laufen Märkte besser, wenn der Zahlungstermin früh oder spät vor dem Markt
+  liegt?
+- Gibt es einen Zusammenhang zwischen dem Zeitpunkt der Zahlung und dem
+  späteren Erlös?
+- Gibt es Unterschiede zwischen Märkten vor und nach dem eigenen Zahlungstag?
+
+### 10.4 Gemeinde und wirtschaftliches Umfeld
+
+Der Ort soll später über die Gemeinde mit zusätzlichen wirtschaftlichen Daten
+vergleichbar sein.
+
+Zu prüfen ist insbesondere die Hypothese, dass Märkte in Gemeinden mit höherem
+durchschnittlichem Einkommen möglicherweise einen höheren Erlös erzielen als
+Märkte in Gemeinden mit tieferem Einkommen.
+
+Auswertungen:
+
+- Zusammenhang zwischen Gemeinde und Erlös
+- Zusammenhang zwischen Gemeinde-Einkommen und Erlös
+- Zusammenhang zwischen Kaufkraft und Anzahl verkaufter Artikel
+- Vergleich verschiedener Gemeinden
+- Vergleich ähnlicher Märkte in Gemeinden mit unterschiedlichem
+  Einkommensniveau
+
+Die Quelle, Aktualisierung und fachliche Ownership der zusätzlichen
+wirtschaftlichen Gemeindedaten sind noch nicht spezifiziert.

+# Editable Action Card
+
+## Zweck
+
+`Editable Action Card` ist ein fachlich neutrales UI-Pattern fuer Karten mit
+Titelaktionen, Lesemodus und optionalem Bearbeitungsmodus.
+
+Das Pattern kapselt nur die technische Interaktion:
+
+- Umschalten zwischen Lese- und Bearbeitungsansicht
+- Abbrechen einer Bearbeitung
+- optionale Loeschbestaetigung mit konfigurierbarem Token
+- Deaktivieren der Loeschaktion bis zur gueltigen Bestaetigung
+- gleichzeitiges Bearbeiten mehrerer Karten
+
+Fachliche Aktionen, API-Aufrufe, Validierung und die Aktualisierung fachlicher
+Daten bleiben beim owning Modul.
+
+## Markup-Vertrag
+
+Eine Karte wird mit `data-shared-editable-action-card` markiert. Die
+Bedienelemente verwenden folgende Attribute:
+
+- `data-shared-editable-card-edit`
+- `data-shared-editable-card-cancel`
+- `data-shared-editable-card-read`
+- `data-shared-editable-card-form`
+- optional `data-shared-editable-card-delete`
+- optional `data-shared-editable-card-delete-confirmation`
+- optional `data-shared-editable-card-delete-input`
+- optional `data-shared-editable-card-delete-submit`
+- optional `data-shared-editable-card-delete-cancel`
+
+Das Loesch-Token wird je Karte mit
+`data-shared-editable-delete-token` konfiguriert. Die Standardaktion fuer das
+Loeschen bleibt im owning Modul und verwendet den bestehenden fachlichen
+Handler.
+
+## Nutzung im Lager
+
+Im Lager-Drawer verwenden die aktive Charge und offene Chargen das Pattern.
+Rein lesende Karten, insbesondere historische und virtuelle Chargen, bleiben
+beim bestehenden Content-Card-Pattern.

+# Technische Architektur
+
+Stand: 2026-04-08
+Status: Verbindlicher Architektur-Master
+Dokumentklasse: normative
+
+## 1. Zweck und Geltung
+
+Dieses Dokument ist die verbindliche Architekturvorgabe fuer die Entwicklung hochmodularer Webportale in diesem Repository. Es steuert Analyse, Implementierung, Refactoring und Review durch Mensch und LLM.
+
+Verbindliche Betriebsregel:
+
+- Entwicklung und erste Integration erfolgen lokal auf `feature/<thema>` im lokalen Docker-Stack.
+- `main` ist der gemeinsame, auf DEV betriebene Integrationsstand. Ein Feature wird erst nach lokaler Verifikation und expliziter Freigabe nach `main` gemergt.
+- PROD wird ausschliesslich durch das bestehende Release-Skript mit einem expliziten Release-Tag eines in DEV getesteten `main`-Commits ausgerollt und nur nach expliziter User-Freigabe angefasst.
+
+Es definiert verbindlich:
+
+- Modul-, Prozess-, Frontend-, API- und Datenbankgrenzen
+- Ownership und oeffentliche Schnittstellen
+- Standard-Scope fuer Analyse und Implementierung
+- Wiederverwendungs- und Redundanzregeln
+- Regeln fuer neue Module, Submodule und zentrale Bausteine
+
+Dieses Dokument ist kein Inventar konkreter Tabellen, Prozesse, Dateien oder Runtime-Artefakte. Solche Details liegen in den zustaendigen Modul-, Prozess- oder DB-Vertraegen.
+
+## 2. Architekturprinzipien
+
+### 2.1 Module
+
+Ein Modul ist ein fachlich oder technisch gekapselter Contract, nicht nur eine Verzeichnisstruktur.
+
+Verbindliche Regel:
+
+- jedes Modul besitzt genau eine klar abgegrenzte Primaerverantwortung
+- jedes Modul kapselt seine Domain-Logik, Datenzugriffe, externen Schnittstellen, internen Datenstrukturen und Speicherdetails
+- jedes Modul definiert eine explizite oeffentliche Schnittstelle fuer andere Module
+- jedes Modul besitzt definierte Owned Artefakte und Schreibrechte
+- interne Implementierungen anderer Module duerfen nicht direkt genutzt werden
+- jede Modulgrenze muss als potenzielle spaetere Service-Grenze behandelbar bleiben
+
+### 2.2 Prozesse
+
+Ein Prozess ist ein sequenzieller Hauptablauf innerhalb genau eines owning Hauptmoduls.
+
+Verbindliche Regel:
+
+- ein Hauptmodul besitzt beliebig viele Hauptprozesse; jeder Hauptprozess gehoert genau einem Hauptmodul
+- ein Hauptprozess darf Submodule desselben Hauptmoduls nutzen
+- fachliche Hauptprozesse ueber Hauptmodulgrenzen hinweg sind nicht zulaessig
+- Batching, Parallelisierung, Retry, Resume, Fehlerklassifikation, Statusermittlung und Ergebnisvertrag gehoeren in den owning Prozessvertrag
+- zusaetzliche harte Schreib-, Feld- oder Datenbankschranken sind nur zulaessig, wenn sie explizit im Prozess- oder DB-Vertrag festgelegt sind
+
+Verbindliche Kettenarten:
+
+- asynchrone Prozessketten: ein Startprozess stoesst Folgeprozesse an, diese laufen als eigene Runs weiter
+- synchrone Prozessketten: Subprozesse haengen direkt aneinander; jeder Schritt stoesst nur den naechsten an
+- der Kettenmodus muss pro Prozessvertrag explizit festgelegt sein
+- die Wahl des Kettenmodus erfolgt jeweils nach fachlichem Sinn und Prozessvertrag
+
+Aktive Prozesswahrheit:
+
+`docs/modules/<modul>/<submodul>/processes/`
+
+Verbindliche Regel:
+
+- Prozess- und Sub-Prozess-Dokumente unter diesem Pfad sind die aktive fachliche Wahrheit
+- Prozessnomenklatur folgt `component.subcomponent.process_name`
+- jeder Hauptprozess und jeder Sub-Prozess besitzt genau einen owning Modulpfad
+- `docs/system_components/` darf fuer aktive Prozessreferenzen nicht verwendet werden
+
+### 2.3 Implementierung
+
+Module, Prozesse und Sub-Prozesse sind technisch so scharf wie moeglich zu trennen.
+
+Verbindliche Regel:
+
+- jedes Modul besitzt eine interne API oder Zugriffsschicht
+- Cross-Modul-Kommunikation erfolgt nur ueber definierte Modul-Schnittstellen
+- direkte Zugriffe auf interne Implementierungen oder Daten anderer Module sind verboten
+- neue APIs im geschuetzten Bereich sind standardmaessig `protected`; die Abo-Pruefung greift vor jeder Datenlieferung
+- Module, Prozesse und Sub-Prozesse muessen getrennt entwickelbar, testbar, ausrollbar, ueberwachbar, debugbar und optimierbar sein
+- technische Kopplung zwischen Prozessen und Sub-Prozessen ist auf das notwendige Minimum zu reduzieren
+- Module duerfen keine impliziten Abhaengigkeiten besitzen, die eine spaetere Extraktion verhindern
+
+### 2.4 Frontend
+
+Das Frontend ist bewusst minimalistisch. Ziel ist eine kleine Zahl konsistenter, wiederverwendbarer UI-Bausteine statt vieler seiten- oder feature-spezifischer Sonderkomponenten.
+
+Verbindliche Regel:
+
+- Seiten und Views komponieren Daten, Layouts und Komponenten, erzeugen aber keine Fachlogik
+- UI-Komponenten duerfen keine fachliche Primaerlogik, fachliche Dateninterpretation oder eigenstaendige Fachwahrheit besitzen
+- fachliche UI-Komponenten, fachliche Darstellungsregeln und fachlich interpretierende UI-Logik gehoeren zum owning Fachmodul
+- fachlich neutrale UI-Komponenten, Layout-Komponenten, Formatierungshelfer, Interaktionsmuster und Frontend-Utilities gehoeren nach `shared`
+- neue oder geaenderte Frontend-Komponenten muessen zuerst gegen bestehende Komponenten, Patterns und `shared`-Bausteine geprueft werden
+- Varianten bestehender Komponenten sind ueber Props, Konfiguration oder dokumentierte Erweiterungspunkte umzusetzen, nicht durch Copy-Paste
+- Sortierung, Filterung und Suche werden serverseitig im owning Modul bzw. in der API umgesetzt; das Frontend rendert nur die Ergebnisse
+- Karten, Tabellen, Filter, Tabs, Buttons, Statusanzeigen, Ladezustaende, Empty States, Fehlermeldungen und Detailansichten sind als wiederverwendbare Patterns zu behandeln
+- seitenlokale Sonderkomponenten sind nur zulaessig, wenn sie nachweislich nicht sinnvoll wiederverwendbar sind
+- API-Responses duerfen frontendnah komponiert sein, aber keine Fachlogik aus dem owning Modul in API oder Frontend verschieben
+- Seiten mit externen Redirect- oder Callback-Flows muessen Browser-History und Ruecksprungverhalten bewusst behandeln; der verbindliche Detailvertrag liegt zentral unter `docs/modules/shared/ui_foundation/`.
+
+### 2.4.1 Mehrsprachigkeit
+
+Mehrsprachigkeit ist ein verbindlicher Teil der Frontend-Architektur und gilt identisch fuer statische Texte, dynamisch gerenderte Texte und interaktive UI-Elemente.
+
+Verbindliche Regel:
+
+- jeder sichtbare GUI-String muss ueber einen i18n-Key aufgeloest werden, unabhaengig davon, ob er serverseitig, clientseitig oder aus einer API-Komposition gerendert wird
+- dazu gehoeren insbesondere Navigationslabels, Tab-Titel, Buttontexte, Menuepunkte, Tooltips, Hilfetexte, Platzhalter, Empty States, Ladezustände, Fehlermeldungen, Bestätigungsdialoge, ARIA-Labels und sonstige Screenreader-Texte
+- source-code-Defaults sind nur Fallback- bzw. Seed-Werte; die Anzeige-Wahrheit wird pro Locale aus dem i18n-Store bezogen
+- interaktive Elemente muessen sichtbare Beschriftung und funktionalen Wert strikt trennen: der angezeigte Text ist uebersetzbar, der Wert fuer State, Transport, Routing, Filterung und Backend-Verarbeitung bleibt technisch stabil und locale-unabhaengig
+- Auswahlwerte, Keys, IDs, Data-Attribute, Option-Keys, Tab-Keys und sonstige Steuerungswerte duerfen nicht aus uebersetzten Labels abgeleitet werden
+- Locale-Wechsel darf ausschliesslich die Anzeigeschicht wechseln; Funktion, Auswahlzustand, Navigation, Filterlogik und Datenuebergabe muessen identisch weiter funktionieren
+- wenn Text im DOM sichtbar ist, gilt er als GUI-String und unterliegt dieser Regel auch dann, wenn er clientseitig zusammengesetzt wird
+- zusammengesetzte UI-Texte duerfen keine fachliche Logik enthalten; sie kombinieren nur locale-gebundene Textbausteine mit stabilen technischen Werten
+
+## 3. Modulmodell
+
+### 3.1 Zulaessige Modulbereiche
+
+Fachliche Hauptmodule:
+
+- `company`
+- `ratings`
+- `groups`
+- `lists`
+
+Technische Modulbereiche:
+
+- `system`
+- `shared`
+
+Verbindliche Regel:
+
+- fachliche Hauptmodule besitzen Business-Logik und fachliche Ownership
+- `system` enthaelt nur technische Runtime-, Start-, Trigger- und Laufzeitlogik
+- `shared` enthaelt nur fachlich neutrale, wiederverwendbare technische Bausteine
+- konkrete Submodule, Prozesse, Artefakte und Schnittstellen werden in Modulvertraegen dokumentiert, nicht in diesem Architektur-Master
+
+### 3.2 `shared`
+
+`shared` ist der zentrale technische Querschnittsbereich.
+
+Verbindliche Regel:
+
+- `shared` darf keine Business-Logik, Fachwahrheit oder primaere fachliche Ownership besitzen
+- `shared` darf Services, Komponenten, Helper, technische Schnittstellen, UI-nahe und API-nahe Bausteine bereitstellen
+- ein Baustein gehoert nur nach `shared`, wenn er fachlich neutral ist und keine Verantwortung eines Fachmoduls uebernimmt
+- fachliche Regeln, Dateninterpretation, Statuslogik und Entscheidungen bleiben im owning Fachmodul
+- technische Querschnittslogik ohne fachlichen Inhalt muss in `shared` oder einem dort dokumentierten zentralen Baustein liegen, sobald Wiederverwendung ueber mehr als eine Stelle absehbar ist
+
+### 3.3 `admin`
+
+`admin` ist kein Hauptmodul und besitzt keine fachliche Ownership.
+
+Verbindliche Regel:
+
+- Admin-Funktionen sind nur Bedienoberflaechen auf bestehende Hauptmodule
+- Admin-spezifische Fachlogik liegt im owning Hauptmodul
+- ein separates fachliches Modul `admin` ist nicht zulaessig
+
+### 3.4 `public/api/`
+
+`public/api/` ist die HTTP-Service- und Kompositionsschicht des modularen Monolithen.
+
+Verbindliche Regel:
+
+- `public/api/` besitzt keine fachliche Primaerverantwortung
+- `public/api/` darf Modul- oder Submodul-Schnittstellen fuer konkrete Frontend-User-Stories zusammensetzen
+- `public/api/` bleibt duenn und enthaelt nur HTTP-nahe und technische Kompositionslogik
+- fachliche Ownership darf nicht aus Modulen in `public/api/` wandern
+
+## 4. Datenbankgrenze
+
+Die Plattform nutzt aktuell genau eine gemeinsame Datenbank. Diese gemeinsame Datenbank hebt Modul- und Ownership-Grenzen nicht auf.
+
+Verbindliche Regel:
+
+- jede Tabelle, View, materialisierte View und DB-Funktion besitzt genau eine primaere Ownership
+- primaere Ownership folgt genau einem Hauptmodul oder einem technischen Shared-Bereich
+- fachliche Beziehungen sowie Ownership- und Berechtigungsschluessel verwenden stabile interne Entitaets-IDs; veraenderliche Attribute wie E-Mail, Username oder Anzeigename duerfen dafuer nicht verwendet werden
+- nur das owning Modul definiert Struktur, Write-Logik, Constraints und fachliche Semantik eines DB-Artefakts
+- direkte Cross-Modul-Writes in fremde Owned Tabellen sind verboten
+- andere Module duerfen fremde Artefakte nur ueber definierte Schnittstellen des owning Moduls nutzen
+- physische DB-Splits sind kein aktueller Standard und beduerfen einer expliziten Architekturentscheidung
+
+Operative DB-Referenz:
+
+`docs/database/module_db_ownership.md`
+
+Verbindliche Regel:
+
+- konkrete DB-Artefaktlisten gehoeren in die DB-Ownership-Dokumentation, nicht in diesen Architektur-Master
+- bei Analyse, Refactoring und Implementierung wird der DB-Scope zuerst ueber Modul plus Owned DB-Artefakte bestimmt
+- fremde DB-Artefakte duerfen nur bei deklarierter Leseabhaengigkeit, FK-Beziehung oder Integrationspruefung in den Scope aufgenommen werden
+
+## 5. Dokumentation und Lesescope
+
+Aktive Dokumentation ist komponentennah.
+
+Verbindliche Regel:
+
+- aktive Modul- und Submodul-Dokumentation liegt unter `docs/modules/<modul>/...`
+- aktive technische Shared-Dokumentation liegt unter `docs/modules/shared/...`
+- technische Runtime-Dokumentation liegt unter `docs/modules/system/...`
+- fachliche Hauptprozesse liegen innerhalb des owning Modulbaums
+- historische oder abgeloeste Dokumentation liegt ausserhalb des aktiven Modulbaums
+- `docs/technical_architecture.md` bleibt der einzige aktive Architektur-Master
+
+Standard-Lesescope:
+
+- Arbeit an einem Modul: `docs/technical_architecture.md` plus `docs/modules/<modul>/...`
+- Arbeit an einem Submodul: `docs/technical_architecture.md` plus `docs/modules/<modul>/<submodul>/...`
+- `docs/modules/shared/...`: nur bei betroffener Shared-Schnittstelle oder moeglicher Wiederverwendung
+- `docs/modules/system/...`: nur bei Runtime-, Queue-, Scheduler-, Trigger- oder Supervisor-Themen
+- andere Module: nur bei explizitem Integrationsbedarf
+
+## 6. Wiederverwendung und Redundanzverbot
+
+Vor jeder Aenderung an App, Frontend, UI-Komponenten, UI-Patterns, API, Prozesslogik, Datenzugriff, Infrastruktur oder Dokumentation ist Wiederverwendung vor Neuerstellung zu pruefen.
+
+Ziel ist eine Architektur ohne redundante Fachlogik, technische Inselloesungen, doppelte UI-Komponenten oder mehrfach gepflegte Varianten desselben Musters.
+
+Verbindliche Regel:
+
+- zuerst bestehende Muster, Komponenten, Services, Modul-Schnittstellen und `shared`-Bausteine pruefen
+- vorhandene passende Muster muessen wiederverwendet, erweitert oder als zentrale Schnittstelle bereitgestellt werden
+- fachliche Inhalte gehoeren immer in das owning Fachmodul und werden von dort ueber definierte Schnittstellen bereitgestellt
+- fachliche Logik darf nicht in `shared`, `public/api/`, `admin`, Skripte oder fachfremde Bereiche ausgelagert oder dupliziert werden
+- fachlich neutrale technische Logik gehoert nach `shared`, sofern sie wiederverwendbar ist oder Wiederverwendung absehbar ist
+- Frontend-Darstellung, Interaktionslogik, Layout, Formatierung und Zustandsdarstellung sind als bestehende oder neue zentrale UI-Komponenten beziehungsweise UI-Patterns in `shared` zu pruefen
+- neue `shared`-Bausteine sind nur zulaessig, wenn sie keine Fachwahrheit enthalten, keine fachliche Primaerverantwortung uebernehmen und wiederverwendbar sind
+- technische Querschnittsbausteine duerfen Module entkoppeln, aber keine fachlichen Entscheidungen aus owning Modulen herausziehen
+- neue Loesungen sind nur zulaessig, wenn kein passendes bestehendes Muster, keine passende Modul-Schnittstelle und kein geeigneter `shared`-Baustein existiert
+- Quickfixes, Workarounds, Copy-Paste-Varianten, seitenlokale UI-Duplikate und isolierte Sonderlogik fuer Einzelstellen sind verboten
+- Redundanzvermeidung muss bei Analyse, Umsetzung, Review und Refactoring aktiv nachgewiesen werden koennen
+
+## 7. Verbotene Strukturen
+
+Nicht zulaessig sind:
+
+- Module als reine Ordner ohne Contract
+- direkte Cross-Modul-Zugriffe auf DB-Tabellen, interne Implementierungen oder Daten anderer Module
+- versteckte oder implizite Modulabhaengigkeiten
+- Vermischung mehrerer Primaerverantwortungen innerhalb eines Moduls
+- parallele Fachlogik ausserhalb des owning Moduls
+- redundante fachliche, technische oder UI-Loesungen, obwohl ein bestehendes Modul, eine Schnittstelle, ein Pattern oder ein `shared`-Baustein erweitert werden koennte
+- neue generische Frameworks oder Orchestrator-Umbauten ohne explizite Architekturentscheidung
+- implizite Schutz-, Schreib- oder Datenbankschranken ohne Prozess- oder DB-Vertrag
+
+## 8. Erweiterungsregeln
+
+Neue Hauptmodule, Submodule oder zentrale Bausteine duerfen nur eingefuehrt werden, wenn bestehende Strukturen die Verantwortung nicht sauber tragen koennen.
+
+Prueffragen vor jeder Erweiterung:
+
+1. Welches bestehende Hauptmodul ist primaer betroffen?
+2. Reicht eine neue Datei, ein neues Submodul oder eine neue Schnittstelle im owning Hauptmodul aus?
+3. Handelt es sich um fachlich neutrale Wiederverwendung, die nach `shared` gehoert?
+4. Entsteht wirklich eine neue Primaerverantwortung mit eigenen Owned Artefakten und Schreibrechten?
+5. Bleibt der Handshake zum Rest des Systems auf minimale Scope-Identifier begrenzt?
+6. Reduziert der neue Schnitt Kopplung und Redundanz, statt sie zu erhoehen?
+
+Verbindliche Regel:
+
+- neue Hauptmodule sind nur zulaessig, wenn eine neue fachliche oder technische Primaerverantwortung entsteht, die nicht sauber in `company`, `ratings`, `groups`, `lists`, `system` oder `shared` aufgeht
+- neue Submodule sind nur zulaessig, wenn innerhalb eines bestehenden Hauptmoduls eine klar isolierbare Verantwortung mit eigener Schnittstelle entsteht
+- neue Prozess- und Sub-Prozess-Dokumente werden im owning Modulpfad angelegt und folgen `component.subcomponent.process_name`
+- `admin`, `public/api/`, `scripts/` oder `lib/` begruenden kein neues fachliches Hauptmodul
+- Bequemlichkeit, Dateigroesse oder kurzfristiger Umbauaufwand rechtfertigen kein neues Hauptmodul
+- vor jeder normativen Architektur- oder Modulerweiterung muss dieses Dokument aktualisiert werden
+
+## 9. Aenderungsregel
+
+Jede strukturelle Aenderung an Hauptmodulen, Modulgrenzen, Prozesszuordnungen, Frontend-Prinzipien, API-Grenzen, DB-Ownership oder primaeren Ownership-Prinzipien muss zuerst in diesem Dokument normativ festgelegt und danach in Detaildokumenten nachgezogen werden.
+
+Verbindlich ist:
+
+- `docs/technical_architecture.md` ist der einzige aktive Architektur-Master des Repositories
+- andere Dokumente duerfen diese Architektur erklaeren, anwenden oder historisieren, aber keine konkurrierende Master-Struktur definieren
+- konkrete Inventare wie Tabellenlisten, Submodullisten, Prozesslisten oder Runtime-Artefakte werden in Detaildokumenten gepflegt und nicht hier dupliziert
+
+## 10. Projektspezifische Architekturvorgaben
+
+Dieses Kapitel enthaelt Architekturentscheidungen, die fuer dieses Projekt
+gelten und nicht Teil der allgemeinen, projektuebergreifend wiederverwendbaren
+Modularitaet sind.
+
+### 10.1 Fachliches Hauptmodul `market_management`
+
+Dieses Projekt besitzt zusaetzlich das fachliche Hauptmodul
+`market_management`. Seine fachliche Ownership, Datenstruktur und
+Schnittstellen werden in den Modulvertraegen unter

+### 10.2 GUI-/MCP-Paritaet
+
+Die MCP-Schnittstelle ist im Grundsatz funktional paritaetisch zur GUI. Ein
+MCP-Nutzer ist hinsichtlich der fachlichen Nutzung einem GUI-Nutzer
+gleichzustellen.
+
+Verbindliche Regel:
+
+- jede fachliche Funktion, die technisch ueber das GUI-Interface verfuegbar
+  ist, muss auch ueber die MCP-Schnittstelle ausfuehrbar sein
+- die Paritaet bezieht sich auf die technischen Moeglichkeiten des Interfaces,
+  nicht nur auf aktuell im GUI dargestellte Funktionen; technisch vorhandene,
+  im GUI nicht angezeigte Funktionen muessen trotzdem ueber MCP verfuegbar sein
+- alle fachlichen Lese-, Anlege-, Aenderungs-, Archivierungs- und
+  Reaktivierungsmoeglichkeiten des GUI-Interfaces muessen im MCP-Interface
+  abgebildet sein
+- GUI und MCP verwenden dieselben fachlichen Validierungen, Berechtigungen,
+  Statusregeln und Ownership-Grenzen; fachliche Logik darf nicht doppelt in
+  GUI und MCP implementiert werden
+- jede Erweiterung oder Aenderung eines GUI-Anwendungsfalls erfordert zwingend
+  die gleichzeitige Pruefung und, falls erforderlich, Anpassung des MCP-Interfaces
+- ein MCP-Nutzer darf gegenueber einem gleich berechtigten GUI-Nutzer weder
+  fachlich eingeschraenkt noch durch abweichende Regeln bevorzugt werden
+- die Paritaet betrifft die fachliche Funktion und den Datenzugriff, nicht die
+  visuelle Darstellung oder den Interaktionsablauf der GUI
