Merge feature/gerbil-residency-toggle: residency checkbox on Gerbil create/edit form [god-QA pending]

god added a `correctDob` (DD.MM.YYYY) decisions field: the matched (name+dob)
record is a DUPLICATE with a wrong birthdate → remap its DOB to correctDob so
dedup MERGES it into the canonical same-named animal. apply_dob_remaps runs
BEFORE dedup (it changes the dedup identity); tolerates a missing file; logged
as "DOB-Remaps: N". First use: Chelsea *15.10.2021 → *02.04.2021 (merges into
the canonical record). test_extract covers the remap + that both records then
share one name+dob identity.

Extractor-only. python + dotnet 121/121 green.

+# GerbilManager CI — Gitea Actions
+# =================================
+# STATUS: ENTWURF — inaktiv bis Julian Gitea Actions aktiviert.
+# Aktivierung: Gitea -> Repository -> Einstellungen -> Actions -> "Actions aktivieren"
+# Anschliessend: Gitea Actions Runner auf der NAS installieren (siehe docs/ops.md).
+#
+# Was dieser Workflow tut:
+#   1. dotnet test (alle xUnit-Projekte)
+#   2. npm test + npm run build (Frontend)
+#   3. Docker-Images bauen und in die Gitea-Registry pushen
+#
+# Registry: truenas:13000  (internes Gitea Container Registry)
+# Images:
+#   truenas:13000/gulum/gerbilmanager-api:latest
+#   truenas:13000/gulum/gerbilmanager-frontend:latest

+

+
+Der Manager ist fertig und läuft. Die alten Daten sind importiert
+(**723 Würfe + 247 Tiere + 99 Fotos** sind drin). Mehrere KI-Funktionen sind
+**fertig gebaut, schlafen aber**, bis ein Gemini-Schlüssel hinterlegt ist.
+Jede offene Frage unten zeigt, **was dadurch blockiert ist**.
+
+---
+
+## A. Für Julian — Konten, Schlüssel, Technik
+
+| # | Was gebraucht wird | Wofür / was es freischaltet | Blockiert gerade |
+|---|---|---|---|
+| A1 | **Gemini API-Schlüssel** (aistudio.google.com → „API-Schlüssel erstellen"). | Schaltet **vier Funktionen auf einmal** frei | KI-Verkaufstexte, Charakterbogen-KI (fertig, schläft), Webseiten-Chat-Editor, KI-Antwortentwürfe im Posteingang |
+| A2 | **Abrechnung aktivieren? (EU/Deutschland)** Die Gemini-AGB verlangen für EU-Nutzer die **bezahlte Stufe** — bei eurem Volumen **praktisch 0 €**, aber eure Daten werden dann **nicht** zum Training genutzt. Empfehlung: **Abrechnung einschalten** (bleibt fast gratis). Alternative für volle Privatsphäre: lokales Modell (Ollama). | Datenschutz (v. a. E-Mail-Inhalte) + AGB-konform | dieselben KI-Funktionen wie A1 |
+| A3 | **Gmail App-Passwort.** Einmalig: Google-Konto → 2-Faktor-Bestätigung aktivieren → „App-Passwörter" → eines für „GerbilManager" erstellen → 16-stelligen Code an Michael. | Posteingang verbinden (Anfragen abrufen + Antworten senden) | E-Mail-Posteingang (live) |
+| A4 | **Domain-Name** (ist registriert ✔) + **Cloudflare-Konto & API-Token** (Berechtigung „Cloudflare Pages → Edit"). | Öffentliche Webseite auf Cloudflare veröffentlichen | Veröffentlichung der neuen Webseite (Ersatz für Jimdo) |
+| A5 | **TrueNAS / Gitea — 4 Antworten:** (a) TrueNAS SCALE-Version? (Electric Eel 24.10+?) (b) Gitea Actions aktiviert/aktivierbar? (c) Eigener Postgres-Container (empfohlen) oder bestehender NAS-Postgres? (d) Welcher Dataset-Pfad für Daten/Backups, und ist Port 80 frei? | Manager auf dem NAS betreiben (Produktiv + Backups + CI) | NAS-Deployment (compose + CI sind fertig vorbereitet) |
+
+## B. Für Julian — kleine Aktionen (jederzeit)
+
+| # | Aktion | Warum |
+|---|---|---|
+| B1 | **`git pull` + App neu starten** auf der laufenden Instanz | Holt den **Such-Fix** + neue Felder (Herkunft-Filter, unscharfe Suche, Charakterbogen). Die laufende Instanz ist sonst auf altem Stand. |
+| B2 | **Firewall-Regel** (PowerShell **als Administrator**): `New-NetFirewallRule -DisplayName "GerbilManager dev" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 5173,5179 -Profile Any` | Damit das Handy deiner Frau im WLAN auf die App kommt. |
+| B3 | **2 Test-Einträge löschen:** „Testmaus E2E…" und „Wurf E2E…" | Übrig gebliebene Test-Einträge aus der Qualitätssicherung. |
+
+---
+
+## C. Für die Züchterin — Genetik-Schreibweise & Import-Prüfung
+
+Diese Antworten laden die **restlichen importierten Daten** nach (die unten
+gelisteten Konflikt-Tiere + Tiere mit Sonder-Kürzeln warten in Quarantäne —
+**nichts ist verloren**; sobald geklärt, werden sie automatisch nachgeladen).
+
+| # | Frage | Blockiert |
+|---|---|---|
+| ~~C1~~ | ✅ **BEANTWORTET** (2026-06-06): `Uw`=`G` (internationale Schreibweise, groß=groß/klein=klein) · `Sls`=`WP` (eine Scheckungsart) · `DP`=Darkpatch (Scheckungsart) · `Dea`=hörend / `dea`=`taub` (Hörfähigkeit, hängt von der Scheckung ab, steht nach `spsp`) · `WFNZ`=Wildfangnachzucht (keine rezessiven Gene) · `RV`=Rückverpaarung · `GV`=Geschwisterverpaarung (RV/GV = Zuchtmethode, kein Gencode). → Michael baut das ein; **damit lösen sich die 5 Konflikte in Abschnitt D2 von selbst** (Gg ≡ Uwuw). | — erledigt |
+| ~~C2~~ | ✅ **BEANTWORTET** (2026-06-06): Ja — **`-` = „Allel unbekannt"** (z. B. `D-` = ein D-Allel unbekannt). Wird beim Import als `?`-Platzhalter übernommen. | — erledigt |
+| ~~C3~~ | ✅ **BEANTWORTET** (2026-06-06): Ja, automatisch zusammenführen — **aber nur wenn auch der Zuchtname gleich ist** (Name + Geburtsdatum + Zuchtname = dasselbe Tier). Wird in die Dedup-Regel eingebaut. (Hinweis: der Extraktor fand bisher 0 Fälle mit gleichem Name+Datum aber verschiedenem Zuchtnamen, also ändert sich an den bestehenden Zusammenführungen nichts — die Regel ist die Absicherung.) | — erledigt |
+| ~~C4~~ | ✅ **BEANTWORTET** (2026-06-06): Ja, **Wurfchronik Teil 2 existiert** — wird gerade überarbeitet, kommt später. Der Importer ist pro Datei wiederholbar (idempotent), also einfach die Datei schicken, sobald fertig → Michael importiert sie nach (keine Doppelungen). | ⏳ Datei folgt, wenn überarbeitet |
+| ~~C5~~ | ✅ **BEANTWORTET** (2026-06-06): **Es gibt KEIN „Schwarzschimmel"** — das war ein Fehler in unserem Katalog. Die korrekten Schimmelarten: `efef` → **Orangeschimmel** · `efef pp` → **Rotaugenschimmel** · `efef gg` → **Silberschimmel** · Kombis z. B. `c[chm]c[chm] efef` → **CP-Orangeschimmel**.

+| C6 | **Die 32 Konflikt-Tiere prüfen** → siehe Abschnitt **D**. | diese 32 Tiere werden erst danach geladen |
+| C7 | *(optional)* Was hat dir bei **Renner Pro** gefehlt? Lieblings-Auswertungen? | mögliche neue Funktionen |
+| ~~C8~~ | ✅ **BEANTWORTET** (2026-06-06): **Himalaya gibt es** — Himalaya = **`A- c[h]c[h]`** (agouti), Hermelin = **`aa c[h]c[h]`** (nicht-agouti). Beide bleiben im Katalog; die Engine unterscheidet bereits korrekt nach A-/aa. — erledigt |
+| C9 | *(optional, technisch)* Bei den **CP-Fuchs-Farben**: Wodurch unterscheiden sich genetisch **CP-Fuchs** ↔ **CP-Blaufuchs** ↔ **CP-Fuchs-Hell**? (Vermutung: Blaufuchs = `dd`-Verdünnung, „-Hell" = `c[chm]c[h]` statt `c[chm]c[chm]` — stimmt das?) Aktuell rechnet das Programm alle drei als „CP-Fuchs"; mit deiner Regel können wir sie genau unterscheiden. Per Hand auswählbar sind sie schon. | Farb-Engine Feinschliff (niedrige Priorität) |
+
+### Hinweis zu C5 — woher kam das falsche „Schwarzschimmel"? (wie gewünscht notiert)
+„Schwarzschimmel" stammt aus **unserem ursprünglichen Farbkatalog** `gerbil-manager-web/src/genetics/catalog.ts` (Genotyp `efef`), den wir ganz am Anfang aus den deutschen Genetik-Quellen (de.wikibooks „Schwarze Augen", rennmauswelten, clan-of-topolino) aufgebaut hatten. Von dort kam es in die DB-Seed-Liste + Stammbaum-Farbchips. → Wird in GEN-3 korrigiert: Schwarzschimmel entfernt, `efef` = Orangeschimmel. *(Falls du der Quelle Bescheid geben willst: es ist die de.wikibooks-Farbgenetik-Seite.)*

+## D. Die 32 Konflikt-Tiere (gleicher Name + Datum, aber widersprüchliche Angaben in mehreren Dateien)
+
+Bitte je Tier kurz sagen, **welche Angabe stimmt**. Gruppiert nach Konflikt-Art.
+Alle Details (sämtliche Genotyp-Varianten + Quelldateien): `tools/import/output/review-report.md`.
+
+### D1 · Im Farbschlag-Feld steht versehentlich ein **Tiername** (Tippfehler) — welcher Farbschlag stimmt wirklich?
+> ✅ **GEKLÄRT (Julian, 2026-06-06):** Ursache gefunden — **ab Spalte K** im Stammbaum stehen pro Tier nur Name / Datum / **Gencode** (KEINE Farbangabe). Der Importer hatte dort fälschlich die Nachbarzelle (z. B. den Namen des nächsten Tiers wie „Tennessee", oder eine Notiz wie „DD-Tumor") als Farbschlag gelesen. **Fix ist beauftragt:** in den tiefen Spalten wird kein Farbschlag mehr ausgelesen, die **Farbe wird aus dem Gencode berechnet**; in den frühen Spalten (Proband/Eltern) bleibt der echte Farbschlag erhalten (z. B. Chesnut = „Kohlfuchsschimmel"). **Chesnut und Tennessee sind getrennte Tiere** (bestätigt). → Nach dem Fix verschwindet D1 von selbst; **keine Aktion nötig.**

+
+| Tier | Konkreter Konflikt — was stimmt? | Status |
+|---|---|---|
+| Firefly v.d. K.C. (*18.12.2019) | D-Locus: **D-** ↔ **DD** | ✅ **D-** (DD war Tippfehler) — Julian |
+| WildFire v.d. K.C. (*05.10.2017) | P-Locus: **P-** ↔ **PP** | ✅ **PP** — Julian |
+| Zuleika v.d. K.C. (*24.10.2015) | D-Locus: **D-** ↔ **DD** | ✅ **DD, Ee, Gg, PP** (`aa c[chm]c[h] DD Ee Gg PP spsp`) — Julian |
+| Milka of LennyLengo (*09.12.2018) | C-Locus: **C-** ↔ **Cc[h]** · E-Locus: **E-** ↔ **EE** | ✅ **Cc[h], EE** (`aa Cc[h] dd EE Gg P- Spsp`) — Julian |
+| Silvain v.d. K.C. (*27.03.2022) | E-Locus: **Ee** ↔ **ee** · P-Locus: **P-** ↔ **Pp** | ✅ **ee, Pp** (`aa c[chm]c[chm] Dd ee[-] Gg Pp Spsp`) — Julian |
+| Ichika v.d. K.C. (*19.04.2020) | E-Locus: **ee** ↔ **ee[f]** | ✅ **ee[f]** (Beibehalten-Regel: `[f]` war vorhanden) — Julian |
+| Daja of Little Rose (*16.05.2021) | Scheckung: **mit `spsp`** ↔ **ohne** | ✅ **mit `spsp`** (Beibehalten-Regel) — Julian |
+| Chelsea v.d. K.C. | ⚠️ **Kein Genotyp-Konflikt** — zwei „Chelsea" mit verschiedenem Datum (\*02.04.2021 / \*15.10.2021) | ✅ **ein Tier, Geburtsdatum 02.04.2021** (15.10.2021 war falsch → zusammengeführt) — Julian |
+
+### D4 · **Marker** unterschiedlich (`WP` / `DP` / `WFNZ` / „hörend" mal vorhanden, mal nicht) — welcher gilt?
+> ✅ **REGEL (Julian 2026-06-06):** „Wenn irgendwo etwas vorhanden war, das anderswo fehlte → **immer beibehalten**." Gilt generell für Marker/Flags und Angaben wie `spsp` oder `[f]` (Vorhandensein gewinnt über Fehlen). Wird zur Standard-Regel im Importer → löst alle „mit/ohne"-Fälle automatisch (z. B. Daja `spsp`, Ichika `[f]`). Greift NICHT bei echten Wert-Widersprüchen (z. B. `DD`↔`D-`, `Ee`↔`ee`) — die brauchen weiter deine Entscheidung.
+>
+> ℹ️ Bei D4 waren die Marker `WP`/`DP`/`WFNZ`/`hörend` in BEIDEN Quellen gleich — also **gar nicht** der Konflikt (und jetzt sowieso Flags). Der echte Konflikt ist beim Genotyp. **3 von 5 dadurch automatisch gelöst:**
+
+| Tier | Konkreter Konflikt — was stimmt? | Status |
+|---|---|---|
+| Vestra von den Schlossmäusen (*08.02.2019) | D-Locus: **D-** ↔ **DD** (WP gleich in beiden) | ✅ **DD** — Julian |
+| Victoria Welby gen. Welby v.d. K.C. (*16.01.2023) | E-Locus: **Ee[f]** ↔ **ee[f]** — **Mutter von „C"!** | ✅ **ee[f]** (`Aa CC D- ee[f] Gg pp Spsp [DP]`) — Julian → C bekommt damit seine Mutter |
+| Hedwig of BGB (*30.10.2019) | (WP/DP/hörend) | ✅ auto-gelöst — sind jetzt Flags, kein Konflikt mehr |
+| Pitari gen. Piti v.d. K.C. (*16.05.2021) | (DP) | ✅ auto-gelöst — DP ist jetzt ein Flag |
+| Little Hero of Black Forest (*22.02.2018) | (WFNZ ± spsp) | ✅ kein Genotyp-Konflikt mehr (WFNZ = Flag) |
+
+### D5 · **Sterbedatum** widersprüchlich

+| Hanami v.d. Kleinen Chaoten (*10.09.2015) | Tod 12.12.2019 vs. 14.01.2020 |
+| ~~Molly of Black Forest (*13.09.2021)~~ | ✅ **Tod 03.05.2022** (03.05.2021 war Jahr-Tippfehler → lag vor der Geburt) — Julian 2026-06-06 |

+
+**Einziger veröffentlichter Port:** `80` (konfigurierbar via `PORT` in `.env`).
+Alles andere läuft intern im Docker-Netz.
+
+---
+
+## 2. Voraussetzungen
+
+| Was | Details |
+|-----|---------|
+| TrueNAS SCALE | Electric Eel 24.10+ (native Docker Custom Apps) |
+| Gitea | http://truenas:13000 — Repository `Gulum/GerbilManager` |
+| Docker | bereits auf TrueNAS vorhanden (Custom Apps nutzen es) |
+| Datasets | Drei ZFS-Datasets anlegen (siehe Schritt 3) |
+
+---
+
+## 3. Erstinstallation auf TrueNAS
+
+### 3.1 ZFS-Datasets anlegen
+
+In TrueNAS → **Datasets** → **Dataset hinzufügen** (je einmal wiederholen):
+
+| Dataset-Name | Empfohlener Pfad | Verwendung |
+|---|---|---|
+| `gerbil/pgdata` | `/mnt/SSD/gerbil/pgdata` | Postgres-Datenbankdateien |
+| `gerbil/photos` | `/mnt/SSD/gerbil/photos` | Hochgeladene Tierfotos |
+| `gerbil/backups` | `/mnt/SSD/gerbil/backups` | Tägliche Backups |
+
+> **Tipp:** Passe die Pool-Bezeichnung (`SSD`) an deinen tatsächlichen Pool an.
+
+### 3.2 Repository klonen
+
+```bash
+# SSH in TrueNAS oder lokale Shell
+git clone http://truenas:13000/Gulum/GerbilManager.git /opt/gerbilmanager
+cd /opt/gerbilmanager
+```
+
+### 3.3 Konfiguration anlegen
+
+```bash
+cp deploy/truenas/.env.example deploy/truenas/.env
+# Jetzt .env bearbeiten:
+nano deploy/truenas/.env
+```
+
+Mindestens setzen:
+- `POSTGRES_PASSWORD` — sicheres Passwort (mind. 20 Zeichen)
+- `PGDATA_PATH`, `PHOTOS_PATH`, `BACKUPS_PATH` — tatsächliche Dataset-Pfade
+
+### 3.4 Images bauen und App starten
+
+```bash
+cd /opt/gerbilmanager
+docker compose -f deploy/truenas/compose.yaml build
+docker compose -f deploy/truenas/compose.yaml up -d
+```
+
+Erster Start dauert ca. 2–3 Minuten (Postgres-Init + EF-Migrationen).
+
+### 3.5 Prüfen
+
+```bash
+# Alle Container laufen?
+docker compose -f deploy/truenas/compose.yaml ps
+
+# API-Healthcheck
+curl http://localhost/api/health
+
+# Webapp im Browser
+http://<NAS-IP>/
+```
+
+---
+
+## 4. App starten / stoppen / aktualisieren
+
+### Starten
+
+```bash
+docker compose -f deploy/truenas/compose.yaml up -d
+```
+
+### Stoppen
+
+```bash
+docker compose -f deploy/truenas/compose.yaml down
+```
+
+### Aktualisieren (nach `git push` auf main)
+
+```bash
+cd /opt/gerbilmanager
+git pull
+docker compose -f deploy/truenas/compose.yaml build
+docker compose -f deploy/truenas/compose.yaml up -d
+```
+
+> EF-Migrationen laufen automatisch beim API-Start — kein manueller Schritt nötig.
+
+### Mit Gitea CI (wenn Actions aktiviert)
+
+Push auf `main` triggert automatisch Build → Test → Image-Push.
+Danach auf der NAS:
+```bash
+docker compose -f deploy/truenas/compose.yaml pull
+docker compose -f deploy/truenas/compose.yaml up -d
+```
+
+---
+
+## 5. Backup & Wiederherstellung
+
+### Automatisches Backup
+
+Der `backup`-Sidecar-Container läuft dauerhaft und sichert täglich um **03:00 Uhr**:
+- Kompletter `pg_dump` der Datenbank als `.sql`
+- Komprimiertes Foto-Archiv als `.tar.gz`
+- Rotation: Backups älter als `BACKUP_KEEP_DAYS` (Standard: 7) werden gelöscht
+
+Backups liegen unter: `${BACKUPS_PATH}/YYYY-MM-DD_HH-MM/`
+
+```
+/mnt/SSD/gerbil/backups/
+  2026-06-06_03-00/
+    gerbilmanager_2026-06-06_03-00.sql   (Datenbank)
+    photos_2026-06-06_03-00.tar.gz       (Fotos)
+  backup.log                              (Protokoll)
+```
+
+### Manuelles Backup auslösen
+
+```bash
+docker compose -f deploy/truenas/compose.yaml exec backup /bin/sh /scripts/backup.sh
+```
+
+### Backup-Log prüfen
+
+```bash
+tail -50 /mnt/SSD/gerbil/backups/backup.log
+```
+
+### Wiederherstellung — Runbook
+
+> **WARNUNG:** Alle aktuellen Daten werden überschrieben!
+
+**Schritt 1:** App stoppen (optional, aber empfohlen)
+```bash
+docker compose -f deploy/truenas/compose.yaml stop api frontend
+```
+
+**Schritt 2:** Restore ausführen
+```bash
+# Neuestes Backup wiederherstellen:
+docker compose -f deploy/truenas/compose.yaml exec backup \
+    /bin/sh /scripts/restore.sh
+
+# Bestimmtes Backup wiederherstellen:
+docker compose -f deploy/truenas/compose.yaml exec backup \
+    /bin/sh /scripts/restore.sh 2026-06-05_03-00
+```
+
+**Schritt 3:** API neu starten
+```bash
+docker compose -f deploy/truenas/compose.yaml start api frontend
+```
+
+**Schritt 4:** Prüfen
+```bash
+curl http://localhost/api/color-varieties | grep -c '"id"'
+# Erwarteter Wert: 73
+```
+
+### Restore-Nachweis (Round-Trip-Test)
+
+Protokoll vom Test auf lokalem Aspire-Postgres (Vorgänger-Instanz, 2026-06-06 07:09):
+```
+73 ColorVarieties vorhanden
+→ DELETE 12 Zeilen → 61 verbleibend
+→ pg_restore eingespielt
+→ 73 ColorVarieties bestätigt
+Exit-Code: 0
+```
+Die Container-Restore-Skripte nutzen dieselbe `psql < dump.sql` Logik.
+**Erster echter Test auf TrueNAS:** nach Erstinstallation bitte ausführen und das Ergebnis notieren.
+
+---
+
+## 6. ZFS-Snapshot-Schichtung
+
+ZFS-Snapshots ergänzen die pg_dump-Backups als zweite Sicherungsebene.
+Sie schützen vor versehentlichem Datenverlust auf Dataset-Ebene.
+
+### Empfohlene Snapshot-Konfiguration
+
+In TrueNAS → **Datasets** → Dataset auswählen → **Snapshots** → **Regelmäßige Snapshots**:
+
+| Dataset | Häufigkeit | Aufbewahrung |
+|---------|-----------|--------------|
+| `gerbil/photos` | Stündlich | 24 Stunden |
+| `gerbil/photos` | Täglich | 30 Tage |
+| `gerbil/pgdata` | Stündlich | 24 Stunden |
+| `gerbil/pgdata` | Täglich | 30 Tage |
+| `gerbil/backups` | Täglich | 90 Tage |
+
+> **Hinweis:** `pgdata` enthält Live-Postgres-Dateien. ZFS-Snapshots davon sind crash-konsistent,
+> aber **nicht** application-konsistent — für einen sauberen DB-Restore immer den `pg_dump` verwenden,
+> nicht den ZFS-Snapshot von `pgdata`.
+
+### Snapshot manuell erstellen (z. B. vor Update)
+
+```bash
+# TrueNAS CLI
+zfs snapshot SSD/gerbil/photos@vor-update-$(date +%Y%m%d)
+zfs snapshot SSD/gerbil/backups@vor-update-$(date +%Y%m%d)
+```
+
+### Aus ZFS-Snapshot wiederherstellen (Fotos)
+
+```bash
+# Snapshot auflisten
+zfs list -t snapshot SSD/gerbil/photos
+
+# Datei aus Snapshot kopieren
+cp /mnt/SSD/gerbil/photos/.zfs/snapshot/<NAME>/datei.jpg /mnt/SSD/gerbil/photos/
+```
+
+---
+
+## 7. CI/CD via Gitea Actions
+
+Der Workflow `.gitea/workflows/ci.yml` ist als **Entwurf vorhanden, aber inaktiv**.
+
+### Aktivierung
+
+1. **Gitea Actions aktivieren:**
+   Gitea → Repository `GerbilManager` → Einstellungen → Actions → "Actions aktivieren"
+
+2. **Gitea Actions Runner installieren** (auf TrueNAS oder einem separaten Gerät):
+   ```bash
+   # Gitea Runner Container (einfachste Variante für TrueNAS)
+   docker run -d --name gitea-runner \
+     -v /var/run/docker.sock:/var/run/docker.sock \
+     -v /opt/gitea-runner:/data \
+     -e GITEA_INSTANCE_URL=http://truenas:13000 \
+     -e GITEA_RUNNER_REGISTRATION_TOKEN=<TOKEN> \
+     gitea/act_runner:latest
+   ```
+   Token: Gitea → Admin → Actions → Runner → "Runner hinzufügen"
+
+3. **Registry-Secrets konfigurieren:**
+   Gitea → Repository → Einstellungen → Secrets:
+   - `REGISTRY_USER` — dein Gitea-Benutzername
+   - `REGISTRY_TOKEN` — Gitea Access Token mit `package:write`-Berechtigung
+
+### Workflow nach Aktivierung
+
+```
+git push origin main
+  → Gitea Actions: dotnet test + npm test + npm run build
+  → Bei Erfolg: docker build + push zu truenas:13000/gulum/
+  → Auf NAS: docker compose pull + up -d
+```
+
+---
+
+## 8. Offene Fragen
+
+Bitte beantworte diese Fragen, damit das Setup fertiggestellt werden kann:
+
+| # | Frage | Auswirkung |
+|---|-------|-----------|
+| 1 | **TrueNAS SCALE Version?** Electric Eel 24.10 hat native Docker Custom Apps. Ältere Versionen nutzen Kubernetes. | Bestimmt ob `docker compose` direkt läuft |
+| 2 | **Gitea Actions verfügbar/aktivierbar?** | CI/CD-Workflow aktiv oder nur manuell deployen |
+| 3 | **Eigener Postgres-Container (empfohlen) oder vorhandene NAS-Postgres-App?** | Isolation vs. geteilte Instanz |
+| 4 | **Genaue Dataset-Pfade?** Poolname und Pfad-Präfix | `.env`-Konfiguration |
+| 5 | **Port-Wahl?** Standard 80 — frei auf der NAS? | `PORT`-Wert in `.env` |
+
+---
+
+## 9. Fehlerbehebung
+
+### App startet nicht
+
+```bash
+# Logs aller Container
+docker compose -f deploy/truenas/compose.yaml logs
+
+# Logs eines bestimmten Containers
+docker compose -f deploy/truenas/compose.yaml logs api
+docker compose -f deploy/truenas/compose.yaml logs db
+```
+
+### Datenbank nicht erreichbar
+
+```bash
+# DB-Container läuft?
+docker compose -f deploy/truenas/compose.yaml ps db
+
+# Verbindung testen
+docker compose -f deploy/truenas/compose.yaml exec db \
+    psql -U postgres -d gerbilmanager -c "\dt"
+```
+
+### Backup-Fehler
+
+```bash
+# Backup-Log prüfen
+cat /mnt/SSD/gerbil/backups/backup.log | tail -30
+
+# Backup manuell starten (mit Fehlerausgabe)
+docker compose -f deploy/truenas/compose.yaml exec backup \
+    /bin/sh /scripts/backup.sh
+```
+
+### Fotos werden nicht angezeigt
+
+Prüfe ob das `photos`-Volume korrekt gemounted ist:
+```bash
+docker compose -f deploy/truenas/compose.yaml exec api ls /data/photos
+```
+
+### Container-Status zurücksetzen (Neustart)
+
+```bash
+docker compose -f deploy/truenas/compose.yaml restart api
+```
+
+### Kompletter Neustart (Daten bleiben erhalten)
+
+```bash
+docker compose -f deploy/truenas/compose.yaml down
+docker compose -f deploy/truenas/compose.yaml up -d
+```
