+# Implementation Foundation
+
+Das neue Zielprojekt liegt in `saas-app/`, damit der bisherige PHP-Bestand
+unangetastet als Referenz bestehen bleibt.
+
+Foundation-Stand:
+
+- Laravel-nahe Ordnerstruktur ohne externe Downloads
+- Tenant-Resolution-Skelett ueber Host/Subdomain
+- Request-Context-Platzhalter
+- Grundrouten fuer Landing, Login und Dashboard
+- erste SQL-Migrationsskizzen fuer:
+  - `tenants`
+  - `users`
+  - `tenant_users`
+  - `roles`
+  - `tenant_user_roles`
+- Blade-Layouts als Platzhalter fuer SSR-Ansatz auf Webspace
+
+Naechste Programmierphase:
+
+1. Identity-/Tenant-Agent auf `saas-app/app` und Auth-/Tenant-Module
+2. Ledger-/Core-Agent auf Mitglieder, Striche, Einzahlungen und Dashboard
+3. spaeter Operations-Agent fuer Importe, Mail, Umfragen und Exporte
+
+Blocker ausserhalb des Repos:
+
+- `php` lokal nicht installiert
+- `composer` lokal nicht installiert
+- echtes Laravel-Scaffolding daher noch nicht moeglich
+
+Sobald Tooling vorhanden ist, soll dieses Geruest in ein vollstaendiges
+Laravel-Projekt ueberfuehrt werden.

+# SaaS App Foundation
+
+Dieses Verzeichnis enthaelt das neue, Laravel-nahe Zielprojekt fuer die
+mandantenfaehige SaaS-Version.
+
+Aktueller Stand:
+
+- downloadfreies Foundation-Geruest
+- modulare Zielstruktur fuer Webspace-Betrieb
+- Tenant-Resolution-Skelett
+- Basismigrationen fuer Mandanten, Benutzer und Rollen
+- einfache Web-Routen und Blade-Platzhalter
+
+Zielrahmen:
+
+- klassischer Webspace / PHP-Hosting
+- SSR-orientiert
+- Cron statt dauerhaft laufender Worker
+- OIDC zuerst, SAML spaeter optional
+
+Hinweis:
+
+Dieses Geruest ersetzt noch kein vollstaendig installiertes Laravel-Projekt.
+Sobald `php` und `composer` verfuegbar sind, soll auf dieser Struktur ein
+vollwertiges Laravel-Projekt aufgesetzt oder diese Struktur in ein solches
+ueberfuehrt werden.
