 # Aktueller Entwicklungsstand
 
-Stand: 19.08.2026
+## Version
 
-## Plugin
+**Bratonien Tools 0.9.6.2**
 
-- Aktuelle Plugin-Version: **0.9.6.1**
-- Aktueller Entwicklungsblock: **NC Connector – WebDAV-End-to-End-Pfad mit Piwigo-Registrierung, Preview-/Derivatstrecke und sauberem Verbindungs-Lebenszyklus**
-- GitHub ist das führende Repository.
-- Der bestehende lokale Connector bleibt vollständig erhalten und wird nicht automatisch migriert.
+## NC Connector
 
-## Nicht verhandelbare Architekturregeln
+Der NC Connector besitzt nur noch einen produktiven Verbindungsweg: **Nextcloud per WebDAV**.
 
-- Nextcloud bleibt die Quelle der Originalbilder.
-- Originalbilder werden **nicht dauerhaft nach Piwigo kopiert**.
-- Der bestehende lokale Produktionsweg bleibt funktionsfähig.
-- WebDAV benötigt nur Nextcloud-Adresse, Benutzer/App-Passwort und normale WebDAV-Berechtigungen des Benutzers.
-- Kein Nextcloud-PostgreSQL-Zugriff, kein `occ`, keine Storage-IDs, keine Host-Mounts, kein FUSE, davfs oder rclone als Voraussetzung.
-- WebDAV-Verbindungen werden voneinander isoliert verarbeitet.
-- Fehler der WebDAV-Bildverarbeitung dürfen keinen normalen Piwigo-Seitenaufruf zum Absturz bringen.
+### Verbindungsmodell
 
-## Bestehende Quellenmodi
+- `adapter=remote`
+- `source_mode=webdav-placeholder`
+- Nextcloud-Adresse, Benutzer und Passwort/App-Passwort werden pro Verbindung verschlüsselt gespeichert.
+- Piwigo-API und Benutzername/Passwort-Fallback werden ebenfalls pro Verbindung gespeichert.
+- Der Assistent zeigt ausschließlich die Verzeichnisse, auf die der angemeldete Nextcloud-Benutzer per WebDAV zugreifen kann.
+- Mehrere Verzeichnisse können pro Verbindung ausgewählt werden.
 
-Weiterhin vorhanden:
+### Laufzeit
 
-- `legacy-view`
-- `user-shares`
-- `selected-fileids`
+Der gemeinsame Runner verarbeitet ausschließlich WebDAV-Verbindungen:
 
-Neuer WebDAV-Modus:
+1. `runtime/reconcile-webdav.php`
+2. `runtime/cleanup-webdav-piwigo.php`
+3. `runtime/sync-webdav.sh` für jede vorhandene WebDAV-Konfiguration
 
-- `webdav-placeholder`
+Die verbindungsspezifischen Runtime-Konfigurationen liegen unter `/etc/bratonien-tools/nc-connector/`. Zustandsdaten liegen unter `/var/lib/bratonien-tools/nc-connector/connection-ID`.
 
-Es gibt keine automatische Migration bestehender Verbindungen auf WebDAV.
+### Shadow Tree und Piwigo
 
-## WebDAV-Ablauf in 0.9.6.1
+`runtime/lib/build_webdav_placeholder_source.py` bildet die ausgewählten Nextcloud-Inhalte als lokale Platzhalterquelle ab. `runtime/lib/shadow_tree.py` erzeugt daraus die Dateisystemstruktur, die Piwigo als physische Site sieht.
 
-1. Der Assistent prüft Nextcloud über WebDAV und lässt sichtbare Verzeichnisse auswählen.
-2. `runtime/reconcile-webdav.php` erzeugt die verbindungseigene Runtime-Konfiguration.
-3. `runtime/lib/build_webdav_placeholder_source.py` liest die ausgewählten Verzeichnisse rekursiv per PROPFIND.
-4. Ordner, Dateinamen, Nextcloud-Datei-ID, MIME-Typ, Größe, ETag und WebDAV-Pfad werden erfasst.
-5. Eine lokale Platzhalterquelle wird erzeugt, ohne Originalbilder dauerhaft zu speichern.
-6. `runtime/lib/shadow_tree.py` baut daraus den verbindungseigenen Shadow Tree.
-7. Der WebDAV-Galeriebaum liegt unter `_data/bratonien-tools/nc-webdav-gallery/connection-ID` und wird als eigene physische Piwigo-Site registriert.
-8. Dadurch erscheint die ausgewählte Nextcloud-Wurzel als normales Piwigo-Album; technische `bratonien-webdav-ID`-Wrapper werden nicht angezeigt.
-9. Vorbereitete Arbeitsbilder liegen unter `_data/bratonien-tools/nc-webdav-preview/connection-ID`.
-10. Arbeitsbilder werden als JPEG beziehungsweise PNG erzeugt und maximal auf 4096 px Kantenlänge begrenzt, damit Piwigos Bildbibliothek sie zuverlässig verarbeiten kann.
-11. Der CLI-Derivat-Builder korrigiert die Piwigo-Bildabmessungen anhand des Arbeitsbilds und erzeugt die aktuell konfigurierten Standard- und Custom-Derivate.
-12. Der normale Frontend-Aufruf erzeugt **keine** Derivate. Fehlt ein Derivat, wird das vorbereitete Bild als sicherer Fallback ausgeliefert.
-13. Originalbilder werden bei echtem Originalabruf serverseitig über `webdav-image.php` aus Nextcloud gestreamt; Nextcloud-Zugangsdaten erscheinen nicht im Browser.
+Jede WebDAV-Verbindung besitzt ihre eigene Piwigo-Site. `runtime/lib/piwigo-sync.php` übergibt genau diese Site an `bratonien.nc.syncProductive` und `bratonien.nc.syncOrphans`. Es gibt keinen zusätzlichen Sync auf Site 1.
 
-## Piwigo-Synchronisierung
+Der Shadow Tree dient ausschließlich dazu, Piwigo die Alben und Bilder als Dateisystemstruktur bereitzustellen. Albumlogik, Dateisynchronisierung und die daraus folgenden Piwigo-Datensätze bleiben Aufgabe von Piwigo.
 
-WebDAV verwendet denselben Piwigo-Synchronisationspfad wie der bestehende Connector, aber mit einer verbindungseigenen physischen Site.
+### Bildauslieferung
 
-Nach der Dateisynchronisierung laufen die vorhandenen Piwigo-Nacharbeiten, darunter Metadaten-, Integritäts-, Kategorie-, Pfad-, Rang- und Cache-Aktualisierungen sowie der Orphan-Abgleich.
+Die Dateien im Shadow Tree sind Platzhalter. `include/webdav_image_runtime.inc.php` erkennt die WebDAV-Zuordnung und ersetzt die Bildquelle bei der Auslieferung durch den zugehörigen Nextcloud-Inhalt. `webdav-image.php` streamt die Bilddaten serverseitig, ohne Nextcloud-Zugangsdaten an den Browser weiterzugeben.
 
-Die direkte produktive Synchronisierung ist derzeit ausdrücklich auf **Piwigo 16.4.0** abgestimmt.
+### Löschen
 
-## WebDAV-Bildausgabe und Derivate
+Eine WebDAV-Verbindung kann unabhängig von ihrer Reihenfolge gelöscht werden. Beim Löschen werden die zugehörige Piwigo-Site und die zugehörigen Piwigo-Datensätze entfernt. Die Originaldateien in Nextcloud bleiben unangetastet. Verwaiste WebDAV-Runtime- und Piwigo-Daten werden vom gemeinsamen Lauf bereinigt.
 
-Wichtige Dateien:
+### Diagnose
 
-- `include/webdav_image_runtime.inc.php` – Zuordnung Piwigo-Bild ↔ WebDAV-Quelle, Preview-/Derivat-Helfer und URL-Filter.
-- `webdav-image.php` – berechtigungsgeprüfter serverseitiger Original-/Preview-Abruf.
-- `runtime/lib/precache-webdav-previews.php` – vorbereitete JPEG-/PNG-Arbeitsbilder ohne dauerhafte Originalkopie.
-- `runtime/lib/build-webdav-derivatives.php` – CLI-Aufbau der konfigurierten Piwigo-Derivate.
+Der Status wird pro Verbindung geführt. Fehler enthalten Zeitpunkt, betroffene Verbindung, Prozesszustand und technische Details. Die Administration zeigt keine lokalen Datenbank-, Storage- oder Mount-Einstellungen mehr an.
 
-Der Frontend-Hook führt keine Bildgenerierung mehr aus. Damit bleibt ein Fehler in GD/Imagick/External ImageMagick auf den Hintergrundlauf begrenzt.
+## Entfernte Connector-Komponenten
 
-## Löschen einer WebDAV-Verbindung seit 0.9.6.1
+Nicht mehr Bestandteil des Plugins sind lokale Nextcloud-Datenbankanbindungen, PostgreSQL-Reader, Source-/Activity-Views, Storage-Mappings, Host-Mounts, lokale Reconcile-/Sync-Skripte, Cutover-/Migrationswerkzeuge und der frühere Simulations-Webservice `bratonien.nc.sync`.
 
-Eine gelöschte WebDAV-Verbindung darf keine weiterhin sichtbaren oder über alte Piwigo-Datensätze erreichbaren Bilder hinterlassen.
+## Prüfpflicht vor Merge
 
-Beim Löschen über die Oberfläche:
+Jede Änderung wird vor dem Merge mindestens mit folgenden GitHub-Actions-Prüfungen validiert:
 
-- werden die zur Verbindung gehörende Piwigo-Site, ihre Alben und Bilddatensätze entfernt;
-- werden zugehörige Piwigo-Derivate entfernt;
-- bleiben die Nextcloud-Originaldateien unangetastet;
-- werden Laufzeit- und Preview-Daten anschließend bereinigt.
-
-Zusätzlich läuft `runtime/cleanup-webdav-piwigo.php` im gemeinsamen Runner. Er erkennt verwaiste WebDAV-Piwigo-Sites, für die keine Connector-Verbindung mehr existiert, und entfernt deren Piwigo-Inhalte sowie Gallery-, Source-, Preview-, State-, Status- und Runtime-Reste. Damit werden auch bereits vor 0.9.6.1 gelöschte Verbindungen nachträglich bereinigt.
-
-## Gemeinsamer Runner
-
-`runtime/run-all.sh` verarbeitet die Schritte in kontrollierter Reihenfolge:
-
-1. lokale Verbindungen reconciliieren;
-2. WebDAV-Verbindungen reconciliieren;
-3. verwaiste WebDAV-Piwigo-Inhalte bereinigen;
-4. verwaiste allgemeine Runtime-Dateien bereinigen;
-5. aktive WebDAV-Verbindungen synchronisieren;
-6. aktive lokale Verbindungen synchronisieren.
-
-Der vorhandene systemd-Timer ruft direkt die Runtime aus dem installierten Plugin auf.
-
-## Status- und UI-Regeln
-
-- Hintergrund-Polling lädt die Admin-Seite nicht neu.
-- Ein geöffneter Verbindungsassistent bleibt bei Statusaktualisierungen geöffnet.
-- Fehlgeschlagene Fallback-/Credential-Prüfungen schließen den Assistenten nicht.
-- Laufzeitfehler unterscheiden WebDAV-Lesen, Piwigo-Synchronisierung, Preview- und Derivatfehler.
-
-## Sicherheit
-
-- Connector-Zugangsdaten werden verschlüsselt gespeichert.
-- WebDAV-Credentials werden nur serverseitig verwendet.
-- Bildzugriffe über `webdav-image.php` werden gegen Piwigos Zugriffsrechte geprüft.
-- Nextcloud-Originale werden weder beim Sync noch beim Löschen einer Verbindung verändert.
-- Derivate und Arbeitsbilder sind lokale Cache-/Arbeitsdaten und dürfen entfernt beziehungsweise neu aufgebaut werden.
-
-## Aktueller Prüfstand
-
-Bereits umgesetzt:
-
-- WebDAV-Verbindungsassistent;
-- Verzeichnisauswahl;
-- rekursiver WebDAV-Scan;
-- Shadow Tree;
-- separate Piwigo-Site je WebDAV-Verbindung;
-- sichtbare Albumstruktur ohne technische Wrapper;
-- echte Bildausgabe aus Nextcloud;
-- lokale vorbereitete Arbeitsbilder;
-- CLI-Derivatstrecke;
-- Piwigo-Nacharbeiten und Orphan-Abgleich;
-- ETag-basierte Wiederverwendung vorbereiteter Bilder;
-- Löschen einer Verbindung einschließlich Piwigo-Inhalten;
-- nachträgliche Bereinigung bereits verwaister WebDAV-Piwigo-Sites.
-
-Weiter zu prüfen beziehungsweise unter realer Last zu härten:
-
-- vollständiger Derivataufbau für alle in der Installation vorkommenden Standard- und Custom-Größen;
-- Verhalten bei großen Bildmengen und vielen gleichzeitig noch nicht vorbereiteten Bildern;
-- Fehlerfälle verschiedener Bildformate und Bild-Backends;
-- langfristige Änderungserkennung und Performance im produktiven Einsatz.
