fix(akte): falscher Hinweis „Weicht vom eingetragenen Farbschlag ab"

Beim Prod-Nachtest aufgefallen: Bei Schecken meldete die Akte eine Abweichung,
obwohl eingetragener und errechneter Farbschlag identisch angezeigt wurden
(JackJack: „Saphir Schecke" vs. „Saphir Schecke"). Zwei Ursachen:

- Der Vergleich schnitt „Schecke"/„Rex" nur auf der ERRECHNETEN Seite ab, nicht
  auf der eingetragenen (die den Zusatz über formatVarietyName trägt). Jetzt
  werden beide Seiten gleich normalisiert.
- formatVarietyName hängte den Modifier auch an, wenn der Katalogname ihn schon
  trägt („Schwarz Schecke" → „Schwarz Schecke Schecke").

Tests: 3 vitest-Fälle zu formatVarietyName, e2e SCHECKE-MISMATCH mit Gegenprobe
(Mock-Tier mit echter Abweichung zeigt den Hinweis weiter).

+  Fehlerberichte (Tickets) der Züchterin abarbeiten: neue Tickets per Subagent
+  triagieren, Rückfragen an die Tickets hängen, beantwortete Tickets wieder
+  aufgreifen, Fixes gebündelt umsetzen und beim Schließen dokumentieren, was
+  gefixt wurde. Nutze diesen Skill, wenn der Nutzer „Tickets abarbeiten /
+  triagieren", „Fehlerberichte bearbeiten" o. Ä. verlangt.
+---
+
+# Ticket-Triage & Abarbeitung
+
+Tickets entstehen über das „Fehler melden"-Feature (`POST /feedback`) und werden
+unter **Hilfe → Meine Tickets** (`/hilfe/tickets`) verwaltet. Dieser Skill
+automatisiert das Triagieren, Rückfragen-Stellen, Umsetzen und Schließen.
+
+## Status-Lebenszyklus (Feedback.Status)
+
+| Status | Bedeutung | Wer ist dran |
+|---|---|---|
+| `Open` | Neues Ticket, noch nicht triagiert | **KI** (triagieren) |
+| `NeedsInfo` | KI hat eine **Rückfrage** angehängt | Züchterin (antworten) |
+| `Answered` | Züchterin hat geantwortet | **KI** (wieder aufgreifen, umsetzen) |
+| `Resolved` | Erledigt — mit `fixNote` (Changelog) | — |
+
+**Zu bearbeiten sind `Open` (neu) und `Answered` (KI wieder dran).** `NeedsInfo`
+wartet auf die Züchterin, `Resolved` ist fertig — beide überspringen.
+
+## Voraussetzungen
+
+- App läuft (Aspire): `dotnet run --project GerbilManager.AppHost`; API auf
+  http://localhost:5179. Siehe `CLAUDE.md` (Architektur, Import→DB-Workflow,
+  Domänenwissen: 6-Jahre-Lebensspanne, Geschwisterverpaarung, Genotyp/E-Locus,
+  `isResident`).
+- Feedback überlebt den Import-Ingest (FK-freie Spalten) — Tickets bleiben
+  erhalten, auch wenn die DB neu befüllt wird.
+
+## Ziel-System: lokal ODER Prod (WICHTIG — zuerst klären)
+
+Die Tickets liegen dort, wo die Züchterin sie meldet — im Regelfall **Prod**
+(TrueNAS Custom-App). Kläre zu Beginn, gegen welches System der Lauf geht, und
+setze die **API-Base-URL** entsprechend für ALLE `feedback`/`gerbils`/`litters`-Aufrufe:
+
+| System | API-Base | Bookmark der Züchterin |
+|---|---|---|
+| **Prod** (Regelfall) | `http://truenas:8090/api` | http://truenas:8090/ |
+| **Lokal** (Aspire) | `http://localhost:5179` | — (App via `dotnet run --project GerbilManager.AppHost`) |
+
+- **Ticket-CRUD läuft immer gegen das Ziel-System** (Prod: `…/api/feedback`).
+  Einzelticket: `GET /feedback/{id}`; nur die offenen: `GET /feedback?status=Open,Answered`
+  (spart den 2-MB-Volldump). Encoding: über Datei holen + Python-UTF-8 lesen.
+- **Untersuchung bleibt lokal**: die Quellen (Stammbaum-xlsx, `_rpro3.db`, Wurfchronik,
+  `output/*.json`) liegen lokal. Datenfixes gehören re-ingest-stabil in
+  `conflict-decisions.json` / `rpro3-decisions.json` — NICHT die Live-DB patchen.
+- **Prod-Re-Ingest ohne SSH** (bevorzugt): lokal `resolved_import.json` generieren
+  (extract → extract_contracts → merge_and_resolve), dann **per HTTP hochladen + ingesten**:
+  ```bash
+  curl -X POST http://truenas:8090/api/import/ingest-resolved/upload \
+    -F "resolved=@tools/import/output/resolved_import.json" \
+    [-F "photos=@neue_fotos.zip"]   # photos optional, nur bei neuen Fotos
+  ```
+  Der Endpoint staget die Datei serverseitig und ruft denselben UPSERT-Ingest auf
+  (manuell/verified/feedback überleben). **DB-Copy vom lokalen Stand ist VERBOTEN**,
+  sobald Prod eigenständig kuratiert wurde — es überschreibt die Prod-Kuratierung;
+  nur der Upsert-Ingest bewahrt sie. (Fallback ohne Endpoint: `resolved_import.json`
+  per `scp` + `docker cp` nach `ix-gerbilmanager-api-1:/tools/import/output/` und
+  `POST …/api/import/ingest-resolved`.)
+- Vor jeder **Prod-Mutation** (Ingest, Ticket-Schließen im großen Stil) kurz beim
+  Nutzer rückversichern.
+
+## Ablauf
+
+### 1. Tickets holen & einteilen
+`curl -s http://localhost:5179/feedback` (neueste zuerst). Encoding-Falle: über
+eine Datei holen (`curl -o raw.json`) und mit `python … .decode('utf-8')` lesen,
+nicht via Windows-stdin-Pipe (sonst Mojibake). Test-/Dummy-Tickets ausschließen.
+Filtere auf `status in (Open, Answered)`. Bei `Answered` zusätzlich das Feld
+`answer` (Antwort der Züchterin) mitnehmen — darauf basiert die Umsetzung.
+
+### 2. Triage per Subagent (ein Agent pro Ticket)
+Nutze die **Workflow-Orchestrierung** (`pipeline`) — einen Triage-Agenten pro
+Ticket. args ASCII-sicher halten (nur id/context/gerbilId/litterId übergeben; die
+deutschen Nachrichten holt der Agent selbst aus `GET /feedback`). Defensive im
+Script: `const tickets = Array.isArray(args) ? args : JSON.parse(args)`.
+
+Jeder Triage-Agent:
+1. liest `CLAUDE.md` + `docs/ticket-triage.md` (falls vorhanden),
+2. holt seinen Ticket-Text (+ `answer` bei `Answered`) aus `GET /feedback`,
+3. untersucht die echten Daten über die API (`GET /gerbils/{id}`, `/litters/{id}`,
+   Eltern verfolgen; `provenance` zeigt Import-Herkunft inkl. verworfener Werte),
+4. liefert strukturiert (StructuredOutput-Schema): `ticketId, title, category,
+   rootCause, recommendation, fixLayer (import-data|import-logic|backend|frontend|
+   genetics-engine), affectedAreas[], overlapKey (Cluster-Slug), effort (S/M/L),
+   confidence, needsUserInfo`,
+5. **terminale Aktion am Ticket selbst** (jeder Triage-Agent schließt seinen
+   Vorgang ab, lässt nichts offen liegen): braucht es Infos von der Züchterin →
+   **Rückfrage ordentlich stellen** (siehe 3); ist die Ursache rein eine Daten-/
+   Code-Korrektur ohne Rückfrage → an den passenden Umsetzungs-Cluster (4)
+   übergeben (NICHT selbst querschnittlich Dateien ändern).
+
+Sammle alle Ergebnisse in **eine Datei** `docs/ticket-triage.md` (Cluster-/
+Überschneidungs-Matrix + offene Rückfragen) — token-schonend per Python aus dem
+Workflow-Ergebnis generieren, nicht 70 KB in den Kontext laden.
+
+### 3. Rückfragen ordentlich stellen (durch den Triage-Agenten)
+Wenn ein Ticket Infos der Züchterin braucht, hängt der Triage-Agent die Rückfrage
+**direkt selbst** ans Ticket:
+`PUT /feedback/{id}` mit `{"question": "<Rückfrage>"}` → Status wird `NeedsInfo`.
+Anforderungen an eine gute Rückfrage: **eine konkrete Frage** (kein Sammelsurium),
+in **einfacher, freundlicher Sprache** für die Züchterin (keine Code-/Fachbegriffe),
+mit dem nötigen Kontext (welches Tier/welcher Wurf, was unklar ist), und mit einer
+klaren Handlungsaufforderung (z. B. „Wie heißt die Mutter von X?"). Die Züchterin
+beantwortet es in der App; beim nächsten Lauf erscheint es als `Answered` und wird
+wieder aufgegriffen.
+
+### 4. Umsetzen — gebündelt nach Cluster (Überschneidungen vermeiden!)
+Die Triage-Matrix zeigt, welche Tickets sich Dateien teilen. Bündele nach
+**datei-disjunkten Workstreams**, damit parallele Subagenten nicht kollidieren:
+- **Genetik-Engine** → `gerbil-manager-web/src/genetics/**`, `tools/import/genotype.py`.
+- **Stammbaum-Import** (Eltern/Dedup/Gender/`isResident`) → `tools/import/extract.py`,
+  `merge_and_resolve.py`, `conflict-decisions.json`.
+- **Frontend-Anzeige** (z. B. Nicht-Bestandstiere ausblenden) → `GerbilDetailPage.tsx`,
+  `de.ts`.
+Gemeinsam genutzte Dateien (`de.ts`, `GerbilDetailPage.tsx`) gehören **genau einem**
+Workstream — sonst sequenziell. Datenkorrekturen, die die Züchterin nennt, als
+Override in `conflict-decisions.json` kodieren (data-driven, re-ingest-stabil).
+Subagenten committen NICHT und re-ingesten NICHT — das koordiniert der Haupt-Loop.
+
+### 5. Import neu einspielen (bei Daten-/Import-Änderungen)
+`python tools/import/extract.py` → `extract_contracts.py` → `merge_and_resolve.py`,
+dann `POST /import/ingest-resolved` (wischt + lädt neu). Danach betroffene Tickets
+gegen die API verifizieren.
+
+### 6. Ticket schließen — MIT Changelog (durch den bearbeitenden Subagenten)
+Der Subagent/Cluster, der den Fix umgesetzt hat, schließt **seine** Tickets selbst
+ab — aber erst **nachdem der Fix verifiziert und (bei Daten-/Import-Fixes) live
+eingespielt ist** (Schritt 5), damit „erledigt" auch stimmt:
+`PUT /feedback/{id}` mit `{"status": "Resolved", "fixNote": "<verständliche
+Erklärung, was korrigiert wurde>"}`.
+**Die `fixNote` ist ein Changelog AUSSCHLIESSLICH für die Züchterin (Laiin) —
+kein technisches Geschwafel.** Harte Regel:
+- Schreib, **was sich für SIE sichtbar geändert hat**, in Alltagssprache; 1–3 Sätze.
+- KEINE Dateinamen, Funktionen, Feldnamen, IDs, Status-Codes, „Resolver/Migration/
+  Genotyp-Parser/isResident/conflict-decisions" o. Ä. Nenne Tiere/Würfe bei ihrem
+  **Namen**, nicht per ID.
+- Sag ggf., was sie tun soll (z. B. „Seite neu laden").
+
+Gut: „Die Mutter von **Yuki** war falsch — sie ist jetzt **Izumi** (vorher stand
+da Benjiro). Bitte den Stammbaum neu laden."
+Gut: „**Hagrid** wird nicht mehr als dein eigenes Tier geführt, sondern nur noch
+als Vorfahre — seine Würfe und der Charakter-Bereich werden nicht mehr angezeigt."
+Schlecht (NICHT so): „assign_parent_roles korrigiert, motherId via
+conflict-decisions.json gesetzt, re-ingest." / „isResident=false gesetzt."
+
+### Abschluss-Regel (wichtig)
+**Kein bearbeitetes Ticket bleibt offen liegen.** Jedes `Open`/`Answered`-Ticket
+endet nach einem Lauf in genau einem Endzustand:
+- **`NeedsInfo`** — Rückfrage wurde ordentlich gestellt (Info fehlt), oder
+- **`Resolved`** — Fix umgesetzt + verifiziert, mit `fixNote`-Changelog.
+Kann ein Ticket weder gefixt noch sinnvoll erfragt werden, stelle trotzdem eine
+klärende Rückfrage (NeedsInfo) statt es offen zu lassen.
+
+## Mehrrundige Rückfragen & Kontext-Kontinuität
+
+Der Dialog kann mehrere Runden haben: `Open → (Rückfrage) NeedsInfo → (Antwort)
+Answered → (KI prüft) ggf. neue Rückfrage NeedsInfo → Answered → … → Resolved`.
+Jede **weitere Antwort** der Züchterin bringt das Ticket wieder auf `Answered` und
+damit erneut in die Bearbeitung (Schritt 1 filtert `Answered` immer mit ein).
+
+**Kontext-Träger ist das Ticket, nicht der Subagent.** Subagenten sind
+sitzungsgebunden — antwortet die Züchterin später (neue Session), existiert der
+ursprüngliche Agent nicht mehr. Daher MUSS der gesamte Verlauf am Ticket hängen
+(Frage/Antwort je Runde) + der Triage-Eintrag in `docs/ticket-triage.md`. Beim
+Wiederaufgreifen eines `Answered`-Tickets lädt der Subagent diesen vollständigen
+Verlauf + die frühere Triage und macht **mit demselben Kontext** weiter (statt bei
+null neu zu untersuchen) — praktisch „derselbe Vorgang, fortgesetzt".
+
+**Innerhalb derselben Session** kann man stattdessen denselben Subagenten direkt
+fortsetzen (SendMessage an seine Agent-ID, Kontext bleibt erhalten) — nur dann ist
+echte Agent-Kontinuität möglich.
+
+Das Datenmodell unterstützt Mehrrunden über einen **Verlauf/Thread** am Ticket
+(mehrere Frage/Antwort-Einträge mit Autor + Zeit), nicht nur ein einzelnes
+Frage/Antwort-Paar — so geht bei weiteren Antworten nichts verloren.
+
+### Internes Agenten-Kontextfeld (für die Züchterin unsichtbar)
+
+Das Ticket hat ein **internes Kontextfeld** (`agentContext`, NICHT in der Züchterin-
+UI sichtbar) — das **Arbeitsgedächtnis** des Agenten. Damit ersetzt das Ticket den
+sitzungsgebundenen Subagenten-Kontext:
+- **Schreiben:** Bei jeder Bearbeitung legt der Agent dort seinen Arbeitsstand ab
+  (kompaktes JSON/Markdown): Befunde, vermutete Ursache, geprüfte Hypothesen,
+  betroffene Dateien/Daten, der Plan, **worauf gewartet wird** (welche Info die
+  Rückfrage klären soll) und schon erledigte Teilschritte.
+- **Lesen:** Beim Wiederaufgreifen eines `Answered`-Tickets liest der Agent zuerst
+  `agentContext` (+ Verlauf + Triage-Eintrag) und setzt **dort an, wo er aufgehört
+  hat** — keine Neu-Untersuchung von null.
+- **Trennung:** `agentContext` ist intern/technisch (darf IDs/Dateinamen/Hypothesen
+  enthalten); die **sichtbaren** Felder bleiben laienverständlich (Frage, Antwort,
+  `fixNote`). `agentContext` wird in der Tickets-Seite NICHT angezeigt.
+- `PUT /feedback/{id}` mit `{"agentContext": "<arbeitsstand>"}` aktualisiert es,
+  ohne den Status zu ändern.
+
+## Verifikation vor „fertig"
+- Code-Fixes: `npx tsc --noEmit`, `npx vitest run`, betroffene `npx playwright test`,
+  `dotnet build`/`dotnet test`, Python-`test_*.py` — grün.
+- Daten-Fixes: in `resolved_import.json` stichprobenartig prüfen, dann re-ingest +
+  API-Check des konkreten Tiers/Wurfs.
+- Jedes erledigte Ticket auf `Resolved` mit `fixNote` gesetzt.
+
+## Hinweise
+- Pro Ticket genau ein Triage-Agent; Umsetzung gebündelt nach Cluster.
+- Encoding: deutsche Texte als UTF-8 (Datei, nicht stdin-Pipe).
+- Nichts committen, bis der Haupt-Loop verifiziert hat; auf `main` arbeiten.

+# CLAUDE.md — GerbilManager
+
+Leitfaden für die Arbeit an diesem Repo. Bitte vor Änderungen lesen.
+
+## Was ist das?
+
+Verwaltungs-App für eine **Rennmaus-Zucht** („Zucht der kleinen Chaoten"): Tiere,
+Würfe, Stammbäume/Ahnentafeln, Genetik (Farbschläge/Genotypen), Gehege, Kontakte
+(Züchter/Abnehmer), Abgabeverträge, Statistik und eine öffentliche CMS-Webseite.
+Single-User (die Züchterin), Daten größtenteils aus bestehenden Quelldateien
+importiert.
+
+## Architektur / Projekte
+
+| Projekt | Zweck |
+|---|---|
+| `GerbilManager.AppHost` | **.NET Aspire** Orchestrator — startet PostgreSQL (Container) + WebAPI |
+| `GerbilManagerWebAPI` | Backend: ASP.NET **Minimal API**, EF Core + Postgres, Endpoints in `Endpoints/`, Entities in `Models/`, DTOs in `Dtos/` |
+| `GerbilManager.ServiceDefaults` | Aspire-Defaults (Telemetry/Health) |
+| `GerbilManager.Tests` | Backend-Tests (xUnit) |
+| `gerbil-manager-web` | Frontend: **React + Vite + TypeScript** (React Router, react-d3-tree für den Stammbaum) |
+| `tools/import` | **Python**-Import-Pipeline (zero-dep), wandelt Quelldateien → `resolved_import.json` |
+
+## App starten (IMMER über Aspire, nicht nur die WebAPI)
+
+```bash
+dotnet run --project GerbilManager.AppHost
+```
+- WebAPI: http://localhost:5179 · OpenAPI: `/openapi/v1.json`
+- Aspire-Dashboard: https://localhost:17004 (Login-Token steht im AppHost-Log)
+- EF-Migrationen werden beim Start automatisch angewandt (`db.Database.Migrate()` in `Program.cs`).
+- Postgres läuft als Container (Name wechselt pro Run, z. B. `postgres-xxxx`); die
+  **Daten liegen in einem persistenten Volume** → überleben Neustarts. DB-Name: `gerbilmanager`.
+
+## Produktion / Deployment (TrueNAS)
+
+Prod läuft als **TrueNAS SCALE Custom-App** `gerbilmanager` auf dem Host **`truenas`**
+(LAN-IP `192.168.2.115`, TrueNAS 25.10 „Goldeye", Docker). Erstinstallation 2026-07-19.
+
+- **Zugriff (Bookmark der Züchterin):** **http://truenas:8090/** · API-Doku: `/scalar`.
+  (Port 80 ist durch den nginx-Reverse-Proxy der NAS belegt → App auf **8090**, LAN-only, keine Auth.)
+- **Sichtbar unter Apps**, weil via `midclt call app.create {custom_app:true, app_name:"gerbilmanager",
+  custom_compose_config_string:<yaml>}` angelegt — **nicht** via `docker compose` (das taucht in Apps
+  NICHT auf). Container: `ix-gerbilmanager-{db,api,frontend,backup}-1`.
+- **5 Dienste:** `db` (postgres:18) · `api` (.NET, EF-Migrationen laufen beim Start) · `frontend`
+  (nginx: SPA + `/api`-Proxy → `api:8080`, Host-Port 8090) · `publicsite` (nginx, **nur intern**,
+  Host-Port **8081** — serviert statisches HTML aus dem `publicsite`-Volume, das die API via
+  `POST /api/publish` schreibt; ohne Publish leer → 404) · `backup` (täglich 03:00 pg_dump +
+  Foto-Archiv, Shell-Scheduler).
+- **App-Home auf dem Pool:** `/mnt/JailStorage/DockerVolumes/gerbilmanager/` mit
+  `pgdata/ photos/ keys/ backups/ scripts/ publicsite/` und `deploy/truenas/{custom-app.compose.yaml,.env,scripts}`.
+  Images aus der Gitea-Registry `git.rismer.de/gulum/gerbilmanager-{api,frontend}:latest`.
+
+### Deployen
+
+**Automatisch (Regelfall):** Push auf `main` → Gitea Actions (`.gitea/workflows/ci.yml`): Tests →
+Images bauen+pushen → Job `deploy` verbindet sich per SSH auf den NAS-Host und ruft
+`deploy/truenas/scripts/truenas-deploy.sh` (→ `midclt app.redeploy`, zieht `:latest` neu, `pgdata`/
+`photos` bleiben erhalten). Braucht die Gitea-Repo-Secrets **`NAS_SSH_HOST`** (=192.168.2.115) und
+**`NAS_SSH_KEY`** (privater Deploy-Key; Pubkey liegt in `/root/.ssh/authorized_keys`).
+
+**Manuell (auf dem NAS-Host):**
+```bash
+sh /mnt/JailStorage/DockerVolumes/gerbilmanager/deploy/truenas/scripts/truenas-deploy.sh
+```
+Legt die App an, wenn sie fehlt (create), sonst redeploy. Rendert `custom-app.compose.yaml` mit den
+Werten aus `deploy/truenas/.env` (enthält `POSTGRES_PASSWORD` — **nur auf der NAS, nie im Repo**).
+
+**Lokale DB → Prod kopieren** (einmalig gemacht): `pg_dump` der Aspire-DB → `psql`-Restore in den
+`ix-gerbilmanager-db-1`-Container (dabei `api` kurz stoppen); Fotos aus `GerbilManagerWebAPI/photo-storage/`
+per `tar | ssh` nach `…/gerbilmanager/photos/`.
+
+### Deployment-Stolperfallen
+- **`/opt` ist auf Goldeye read-only** → App-Home MUSS auf den Pool (`/mnt/JailStorage/...`).
+- **`postgres:18`** legt PGDATA in `/var/lib/postgresql/18/docker` ab und deklariert das Volume als
+  `/var/lib/postgresql`. Mount auf `/var/lib/postgresql/data` (alte v≤17-Konvention) lässt v18 **nicht
+  starten** ("data in unused mount/volume") → db unhealthy → App-Rollback. Immer `/var/lib/postgresql`
+  mounten. (Debian-Image, nicht alpine → Locale `libc/en_US.utf8` = Quell-DB.)
+- Gitea-Runner ist **containerisiert** (Label `ubuntu-latest`, kein `goldeye`, kein Host-/`midclt`-Zugriff)
+  und läuft **`maxParallel=1`** (Jobs sequenziell) — daher der SSH-Weg im Deploy-Job.
+- **Auto-Deploy lief bis 2026-08-19 nie durch** (Runs 99–107 rot), zwei Ursachen: (1) die Repo-Secrets
+  `NAS_SSH_HOST`/`NAS_SSH_KEY` waren nie angelegt → `ssh root@` mit leerem Key („Could not resolve
+  hostname"); jetzt gesetzt, Deploy-Key `gitea-ci-deploy@gerbilmanager` (privat nur im Gitea-Secret,
+  Pubkey in `/root/.ssh/authorized_keys`). (2) Der Runner hat **kein `rsync`**, und der apt-Guard prüfte
+  nur `ssh` → „rsync: command not found". Dateitransfer läuft daher per **`tar | ssh`** (tar gibt es auf
+  beiden Seiten; `-xof` erhält die Modi, Skripte bleiben ausführbar).
+- CI-Run-Status notfalls aus der Gitea-DB: `docker exec -e PGPASSWORD=gitea ix-gitea-postgresdb-1
+  psql -U gitea -d gitea -c "select name,status from action_run_job where run_id=(select max(id) from action_run);"`
+  (`status`: 1=success, 2=failure, 4=skipped).
+
+## Import → DB (3-stufig, WICHTIG)
+
+Die DB wird **nicht** direkt von Python beschrieben. Nach jeder Import-Code-Änderung
+neu generieren UND neu einspielen, sonst zeigt die App den alten Stand.
+
+> **Arbeitsweise (verbindlich, Owner-Regel — aktualisiert 2026-07-12):** Für **variable**
+> (von der Züchterin **nicht** angefasste) Import-Tiere gilt weiter: Datenfehler IMMER **im
+> Importierer** beheben (Pipeline-Code + `conflict-decisions.json` / `rpro3-decisions.json`)
+> und **neu importieren** — für diese Tiere **nicht** die Live-DB patchen. Jeder Importer-Fix
+> muss **re-ingest-stabil** sein (data-driven, deterministische GUIDs).
+>
+> **Neu:** Das Ziel ist **nicht** mehr „Importer perfekt, dann einmal final", sondern
+> **Tier für Tier konvergieren**. Die Züchterin **darf** über die UI kuratieren, und das
+> **überlebt den Ingest** (der wischt **nicht** mehr alles): (a) **manuell angelegte Tiere/
+> Würfe/Kontakte** (`IsManual=true`) und (b) **Overrides** (`GerbilOverride`) für als
+> **„vollständig korrekt"** markierte bzw. **von Hand bearbeitete** Tiere. Deren eigene Felder
+> werden nach jedem Ingest **eingefroren** (Freeze). Siehe „Geprüfte Tiere / Freeze" unten.
+> Zusätzlich zu diesen Overrides überleben weiterhin **Tickets/Feedback**.
+
+```bash
+# 1. Stammbäume + Wurfchronik → animals.json/litters.json (+ Fotos)
+python tools/import/extract.py
+# 2. Abgabeverträge (DOCX) → contracts.json
+python tools/import/extract_contracts.py
+# 3. Dedup, Eltern-Resolver, Provenance, Vertrags-Anreicherung → resolved_import.json
+python tools/import/merge_and_resolve.py
+# 4. In die laufende DB laden (API muss laufen): UPSERT + Freeze
+curl -X POST http://localhost:5179/import/ingest-resolved
+# 4b. Gegen PROD (ohne SSH): resolved_import.json per HTTP hochladen + ingesten
+curl -X POST http://truenas:8090/api/import/ingest-resolved/upload \
+     -F "resolved=@tools/import/output/resolved_import.json"   # [-F "photos=@neue_fotos.zip"] nur bei neuen Fotos
+```
+- **`POST /import/ingest-resolved/upload`** (multipart `resolved` + optional `photos`-ZIP): staged die
+  hochgeladene Datei serverseitig in `Import:SourcePath` und ruft denselben UPSERT-Ingest — damit läuft
+  der Import **gegen Prod ohne SSH/`docker cp`**. Der alte `POST /import/ingest-resolved` (liest die
+  serverseitige Datei) bleibt unverändert. **DB-Copy vom lokalen Stand ist verboten**, sobald Prod
+  kuratiert wurde — nur der Upsert-Ingest bewahrt manuelle/verified/feedback-Zeilen.
+
+- **`IngestResolvedService` (seit 2026-07-12: UPSERT statt Total-Wipe).** Importierte Zeilen
+  (Gerbils/Litters/Contacts) werden **per deterministischer Id gematcht und in place
+  aktualisiert**; **stale** importierte Zeilen (nicht mehr im Payload) werden entfernt (dangling
+  Referenzen manueller Zeilen werden vorher genullt + im Rückgabestring gewarnt). **Nie gelöscht/
+  überschrieben:** Zeilen mit `IsManual=true` sowie **user-eingegebene Sub-Records**
+  (Weights/Health) und Fotos manueller Tiere. **SaleContracts** werden weiter aus dem Payload
+  neu erzeugt (manuelle Verträge sind noch **nicht** geschützt — Folgeaufgabe). Am Ende werden
+  alle **`GerbilOverride`** angewandt (**Freeze** der eigenen Felder) und für verifizierte Tiere
+  der Rohimport-Stand vorher als Drift-Snapshot erfasst.
+- **Feedback + GerbilOverride überleben den Ingest** (werden nicht gewischt) — daher haben sie nur
+  **lose, nullable Guid-Spalten ohne FK** (`Feedback`: GerbilId/LitterId/ContactId; `GerbilOverride`:
+  GerbilId). Dieses Muster für alles nutzen, was Re-Ingests überleben soll.
+- `resolved_import.json` ist **gitignored** (Runtime-Output); `review-report.md` ist getrackt.
+- Deterministische GUIDs via `generate_guid("...")` → stabile IDs über Re-Ingests.
+
+### Quelldateien (lokal/Netzwerk)
+- Stammbäume: `C:\Users\gulum\dev\Sttammbäume\*.xlsx`
+- Wurfchronik: `C:\Users\gulum\dev\Wurfchronik der Kleine Chaoten Teil1.xlsx`
+- Abgabeverträge: `\\truenas\Datengrab\Rennmäuse\Verträge\*.docx` (~1,4k; kann zeitweise offline sein)
+
+## Build & Test
+
+**Frontend** (`cd gerbil-manager-web`):
+```bash
+npx tsc --noEmit          # Typecheck (muss sauber sein)
+npx vitest run            # Unit-Tests
+npx eslint <dateien>      # Lint
+npx playwright test [spec]# e2e (Projekte: desktop + phone), läuft gegen Mock-API
+```
+- e2e nutzt einen **Mock-Modus** (`e2e/mock-api.ts` + `e2e/mock-data.ts`), kein echtes Backend.
+  Neue API-Routen/Felder dort spiegeln. `skipUnlessMock()` am Testanfang.
+
+**Backend**:
+```bash
+dotnet build
+dotnet test                                   # GerbilManager.Tests
+dotnet ef migrations add <Name> --project GerbilManagerWebAPI   # neue Migration
+```
+- Zum Bauen muss eine laufende WebAPI ggf. gestoppt werden (Datei-Lock auf `bin`).
+
+**Python** (`cd tools/import`, zero-dep, exit 0 = pass):
+```bash
+python test_extract.py  test_extract_docx.py  test_genotype.py  test_merge_resolve.py  test_extract_contracts.py
+```
+
+## Konventionen (bitte einhalten)
+
+- **Alle deutschen UI-Texte in `gerbil-manager-web/src/strings/de.ts`** — niemals in
+  Komponenten hartkodieren.
+- **EF-Migration** für jede Schema-Änderung; wird beim Aspire-Start angewandt.
+- **Provenance/Datenherkunft** liegt als **JSON-Text-Spalte** (`Provenance`) auf
+  Gerbil/Contact/Litter → JSON-Feld-Erweiterungen brauchen **keine** Migration.
+- **Lose nullable Guid-Spalten ohne FK** für Tabellen, die den Ingest-Wipe überleben.
+- Commits: nur wenn der Nutzer es verlangt; auf `main` wird gearbeitet (Remote: `http://truenas:13000/Gulum/GerbilManager.git`). Commit-Messages auf Deutsch, Format `feat(scope): …`.
+- Subagenten committen NICHT — Haupt-Loop verifiziert und committet.
+
+## Domänenwissen (Rennmaus-Zucht)
+
+- **Lebensspanne ~6 Jahre** → ein Elternteil kann max. ~6 Jahre älter als sein Kind
+  sein und muss vorher geboren sein (`parent_age_plausible` im Import; verwirft
+  unplausible Eltern-Links).
+- **Geschwisterverpaarung** (Vollgeschwister als Eltern): erkannt, wenn Vater & Mutter
+  **dieselbe `litterId`** ODER **dasselbe Geburtsdatum** teilen (gleiches DOB = starkes
+  Indiz). UI: Diagramm führt den Vorfahren-Ast zusammen (Verweis-Knoten); Akte zeigt
+  „⚭ Geschwisterverpaarung"-Chip.
+- **Box-Farbe im Stammbaum-xlsx = Geschlecht**: weiß = weiblich, blau = männlich.
+- **Bestandstier (`isResident`) vs. reiner Vorfahre** (Regel der Züchterin, Ticket 09bcac78):
+  Ein Tier ist **ihr Zuchttier** ⇔ es hatte bei ihr Nachzucht mit Herkunft **„von den
+  Kleinen Chaoten"** (nur dann konnten die Jungtiere ihren Zuchtnamen tragen). Trägt die
+  Nachzucht einen **fremden** Herkunftsnamen (z. B. „of Black Forest", „of Topolino"), ist
+  das Tier nur **Vorfahre** (`isResident=false`, keine Würfe/Charakter-Bereich). **Ausnahme:
+  zugekaufte Zuchttiere** (fremder Herkunftsname, aber bei ihr gezüchtet → Nachzucht „von den
+  Kleinen Chaoten") bleiben **Bestandstiere** (z. B. Echo/Elia of Black Forest).
+  **Sweep umgesetzt (2026-06-27, Ticket 381f7e51):** Der Wurfchronik-Import-Default ist
+  **nicht mehr `is_resident=True`**. Neue Regel in `merge_and_resolve.py` (später Sweep
+  nach Eltern-/`addLitters`-Verknüpfung): `isResident=true` **genau dann**, wenn (1) ein
+  expliziter `conflict-decisions.json`-`isResident`-Override greift (gewinnt immer — `true`
+  wie Echo/Elia, `false` wie Akane/Naémi/Bentley), **oder** (2) das Tier **Elternteil eines
+  eigenen Wurfs** ist (nicht-virtuell ODER aus Wurfchronik ODER Clan-Nachzucht ODER mit
+  residentem Elternteil ODER `addLitter` mit `ShowInChronicle`). Reine virtuelle
+  Ahnen-Verpaarungen machen **nicht** resident (z. B. Antares bleibt `false`). Sonst
+  `false`. `ShowInChronicle` wird **nach** dem Sweep berechnet (nutzt die finale Residenz).
+  Effekt: resident **1711 → 442**. UI-Label (`de.ts` `isResidentLabel`) = **„Zuchtanwärter/
+  innen"** — die Züchterin markiert künftige Zuchttiere selbst. **Offene Folgeaufgabe:**
+  manuelle UI-Residenz-Markierungen überleben den Re-Ingest noch **nicht** (bräuchten eine
+  ingest-stabile, FK-freie Override-Ablage analog `Feedback`).
+- **Genotyp/Farbschlag**: 8-Locus-Notation (siehe `tools/import/genotype.py`,
+  `gerbil-manager-web/src/genetics`). Unbekanntes Allel = `-` (nicht `?`).
+  E-Locus: `ee`=Fuchs, `eef`=Fuchsschimmel, `efef`=Schimmel. Rezessiver Fuchs ist
+  zwingend homozygot → `e-` ist ungültig (wirft), `ee[-]`→`ee`.
+- **C-Locus-Zygotie (GEN-6, Tickets bde4ec70/f89e95ad — Regel der Züchterin):** Platin,
+  Saphir und Platin-Hell unterscheiden sich **nur** in der C-Zygotie: `aa CC …pp` = **Platin**,
+  `aa Cc[chm] …pp` = **Saphir**, `aa Cc[h] …pp` = **Platin-Hell**. Der Katalog-Match kann
+  deshalb pro Locus ein **exaktes, ungeordnetes Allelpaar** verlangen — Token-Form `"x/y"`
+  (z. B. `C: 'C/cchm'`), sonst reduziert `locusToken()` auf das dominante Allel und der erste
+  Treffer (Platin) verschluckt die anderen. Gilt in **beiden** Mirrors (`catalog.ts` +
+  `genotype.py`) und im Seed (`colorVarietySeed.*`, `ApplicationContext.SeedColorVarieties`,
+  dort in Kompaktnotation `Ccchm`/`Cch` ohne Klammern).
+- **`c[hm]` ist ein Schreibfehler-Alias für `c[chm]`** (fehlendes c in einigen Stammbaum-Charts):
+  beide Parser normalisieren ihn, sonst ist der Gencode unparsebar bzw. ergibt „…-Hell".
+- **Genetik-Engine = korrektheitskritisch: IMMER vollständig mit Tests absichern.**
+  Jede Änderung an `src/genetics/**` (+ Backend-Mirror + `genotype.py`) braucht pro
+  Use-Case/Ticket einen Regressionstest (`src/genetics/__tests__/genetics.test.ts`
+  und `tools/import/test_genotype.py`), damit nie eine Regression entsteht. `npx vitest
+  run` + `python test_genotype.py` müssen grün sein, bevor „fertig".
+- **Stammbaum-Charts**: Generationen = Spaltenbänder (Proband links in Spalte B/2,
+  je Generation +3 Spalten); Eltern-Position: Vater oben, Mutter unten. Fotos liegen
+  je nach Datei links/auf der Namenszelle — die Seite wird heuristisch über die
+  geringste Spalten-Fehlausrichtung bestimmt (`extract._attach_photos`).
+
+## Stolperfallen
+
+- **Aspire-Containername wechselt** pro Run, das Daten-Volume bleibt → DB-Inhalt
+  überlebt Neustarts (auch alte Schema-Stände → Migrationskonflikte möglich, s. u.).
+- **Migrations-Historie vs. committete Migration-IDs**: Wird eine Migration angewandt
+  und danach mit neuem Zeitstempel neu generiert, sieht EF sie als „pending" und der
+  Start crasht („column … already exists"). Schema ist dann korrekt — nur die
+  `__EFMigrationsHistory`-IDs müssen an die committeten Dateinamen angeglichen werden.
+- **PowerShell + psql**: PascalCase-Identifier (`"__EFMigrationsHistory"`) über
+  PowerShell→docker→psql zerschießen das Quoting. Stattdessen Bash-Heredoc:
+  `docker exec -i -e PGPASSWORD=$PW <container> psql -U postgres -d gerbilmanager <<'SQL' … SQL`.
+  Passwort: `docker exec <container> printenv POSTGRES_PASSWORD`.
+- **Direkte DB-Schreibzugriffe** (psql) werden vom Auto-Mode-Classifier blockiert —
+  vorher beim Nutzer rückversichern.
+- Bash-Tool ist **Git-Bash (POSIX)**, das andere Tool ist **PowerShell** — je eigene Syntax.
+
+## Wo liegt was (Feature-Landkarte)

+  `src/api/feedback.ts`, Backend `Endpoints/FeedbackEndpoints.cs` + `Models/Feedback.cs`.
+- **Geprüfte Tiere / „vollständig korrekt"-Freeze**: Backend `Models/GerbilOverride.cs` (FK-frei,
+  ingest-überlebend), `Import/GerbilSnapshotService.cs` (Akten-Snapshot + Freeze-Map + Diff, von App
+  **und** Test geteilt), `Endpoints/VerifiedGerbilEndpoints.cs` (`/verified-gerbils`: POST markieren,
+  DELETE entfernen/Toggle, GET Liste+Drift, GET `/export` = Golden-Fixture). Freeze wird in
+  `IngestResolvedService` angewandt; `GerbilEndpoints` setzt `IsManual=true` bei POST und legt bei
+  Edit eines importierten Tiers einen per-field-Override an (verifiziert → Golden auto-aktualisiert).
+  Frontend: `src/api/verified.ts`, Badge/Toggle/Drift-Karte in `pages/GerbilDetailPage.tsx`,
+  Übersicht `pages/VerifizierteTierePage.tsx` (`/hilfe/verifizierte-tiere`); Texte in `strings/de.ts`

+  voller Freeze + Regression/Export, `false` = „geschützt" (nur geänderte Felder). Status/Gehege und
+  Abstammung/Nachzucht werden **nicht** eingefroren (nur erkannt/gemeldet). Regressionstest:
+  `GerbilManager.Tests/VerifiedGoldenTests.cs` gegen `tools/import/verified-golden.json` (via
+  `GET /verified-gerbils/export` erzeugen + committen; skippt, wenn Fixture/`resolved_import.json` fehlt).
+  **Scope-Grenze:** Freeze/Override gelten für **Gerbils**; Edits an importierten Würfen/Kontakten und
+  manuelle SaleContracts sind noch **nicht** geschützt (Folgeaufgaben).
+- **Verträge**: `Models/SaleContract.cs`, `Endpoints/ContractEndpoints.cs`,
+  `ContractGenerator.cs`, Frontend `src/pages/Vertraege*`; Import: `extract_contracts.py`
+  + `enrich_from_contracts` in `merge_and_resolve.py`.
+- **Import-Kernlogik**: `tools/import/merge_and_resolve.py` (Dedup, Eltern-Resolver mit
+  Gender-/Alters-Plausibilität, Litter-/Sibling-Dedup, Provenance, Vertrags-Anreicherung).
+- **RennmausPro-III-Import (rpro3)**: Backend-Importer `GerbilManagerWebAPI/Import/Rpro3/*`
+  (`Rpro3ImportService` Analyze/Execute, `Rpro3Dedup` = automatischer Dubletten-Merge, Port von
+  `tools/import/compare_rpro3.py`). **Manuelle Dubletten-Entscheidungen der Züchterin** (aus den
+  „rpro3-import"-Tickets) liegen in `GerbilManagerWebAPI/Import/Rpro3/rpro3-decisions.json` und
+  werden von `Rpro3Dedup.Run(animals, decisions)` honoriert: `same` = Force-Merge (eine rid zieht
+  den Auto-Cluster mit), `different` = Force-Split, `fields` = Feld-Overrides (Farbe/DOB/Herkunft/
+  `genotype` (roher Fcode)/`resident`/Notiz) am Cluster. Der `genotype`-Override ist nötig, wenn
+  Varianten sich im Gencode unterscheiden (z. B. C-Locus c[h] vs. c[chm]) und der Auto-Merge sonst
+  den falschen Gencode (erstes Cluster-Mitglied) zöge — die Züchterin gibt den korrekten vor
+  (z. B. MilkyWay → `aa Cc[h] DD ee Gg P- spsp`). **Schlüssel ist die RPRO3-Nummer (rid), NIE der Variantenbuchstabe**
+  (Buchstaben verschieben sich bei geänderter Clusterbildung) — rids aus dem Ticket-`agentContext`.
+  Triage-Helfer `tools/import/rpro3_lookup.py` (Name- oder `--rids`-Modus) zieht Farbe/Gencode/
+  Eltern/Nachzucht+Partner aus `_rpro3.db` für die Rückfragen an die Züchterin.
+- **Eltern an der Tier-Akte bearbeiten (QOL)**: Im Tier-Formular gibt es den Block
+  **„Abstammung"** (`gerbil-manager-web/src/pages/GerbilFormPage.tsx`) mit Wurf-Auswahl +
+  Vater/Mutter-Picker (`components/AnimalPicker`), damit die Züchterin die Eltern **ohne** den
+  Umweg über die Wurf-Seite pflegen kann. **Datenmodell unverändert**: Eltern hängen weiter am
+  Geburtswurf. Backend `PUT /gerbils/{id}/parents` (`GerbilEndpoints`, DTOs `GerbilParentsInput`/
+  `GerbilParentsResult`, Tests `GerbilManager.Tests/GerbilParentsTests.cs`) schreibt genau dorthin:
+  hat das Tier einen Wurf → dessen `FatherId`/`MotherId` (gilt zwangsläufig für alle Geschwister,
+  die UI warnt mit `siblingCount`); hat es keinen → ein Wurf mit **gleichem Elternpaar + gleichem
+  Datum** wird verknüpft (`litterAttached`), sonst wird ein Träger-Wurf angelegt (`litterCreated`,
+  Name „Wurf von X + Y", `ShowInChronicle=false`, `IsManual=true`). Geschlechts-Validierung
+  wiederverwendet `LitterEndpoints.ValidateParents` (400 `InvalidParentGender`).
+  **Grenze:** Eltern/Abstammung sind vom Freeze **ausgenommen** (`GerbilSnapshotService.FreezeFields`
+  ohne `litterId`) → an einem **importierten** Wurf überlebt eine Eltern-Korrektur den Re-Ingest
+  **nicht** (gleiches Verhalten wie beim Editieren über die Wurf-Seite; dauerhaft nur über den
+  Importer/`conflict-decisions.json`).
+- **Manuell ergänzte Würfe / versteckte Würfe**: `conflict-decisions.json` kennt neben
+  `resolutions`/`addAnimals` auch **`addLitters`** [{name, mother(+motherDob), father, children[],
+  showInChronicle, totalBorn, date, notes}] — materialisiert in `merge_and_resolve.py` als
+  **späten** Schritt (nach Dedup/Parent-Roles, vor json.dump): Wurf mit deterministischer
+  `generate_guid("decision-litter-<slug>")`, verknüpft Mutter/Vater/Kinder per Name(+dob),
+  setzt Kinder-`LitterId`. Die name+dob-Resolutions können zusätzlich `isResident`, `notes`,
+  `receiver` (Kontaktname→ReceiverContactId) auf bestehende Tiere setzen (läuft NACH der
+  Residenz-Propagation). `Litter.ShowInChronicle` (bool, Default true; Migration
+  `AddLitterShowInChronicle`): `false` blendet den Wurf aus der Wurfchronik
+  (`WuerfeListPage`, Filter `showInChronicle==true`) aus, zeigt ihn aber weiter auf der
+  Tier-Akte (parentLitters-Query, ungefiltert). Use-Case: extern entstandener Wurf eines
+  nicht-residenten Tieres (z. B. Akane × Bonaparte).
+- **Über-gemergte Würfe korrigieren**: `conflict-decisions.json` kennt **`litterChildren`**
+  [{date, matchChild, keep[], renameTo?, note}] — autoritative Kinder-Whitelist eines Wurfs
+  (später Schritt in `merge_and_resolve.py` nach `litterOrder`). Match per `date` + `matchChild`
+  (ein aktuell zugeordnetes Kind, disambiguiert gleich-datierte Würfe); Kinder außerhalb `keep`
+  werden aus dem Wurf gelöst (`LitterId=None`, Tier bleibt erhalten), optional `renameTo` setzt
+  den kanonischen Wurf-Namen. Use-Case: Wurfchronik-Abnehmer-Sammelseiten, die fälschlich in einen
+  datierten Buchstaben-Wurf gemergt wurden (Tickets 4b9f49fb M-Wurf, 8d259edf Gale).
+  **`add`** [Name | {name, dob}] ist das Gegenstück (seit 2026-08-18): hängt ein Jungtier an
+  **diesen** Wurf, wenn die Chart-Positions-Heuristik es in einen falschen **virtuellen**
+  Stammbaum-Wurf gezogen hat; wird der alte Wurf dadurch kinderlos UND virtuell, entfernt der
+  Importer ihn (sonst bliebe ein Phantom-Wurf in der Wurfchronik stehen). Use-Case Akane
+  (Ticket 88389f8e): die neuen Stammbäume führen die Eltern eine Zeile unter dem Kind-Block
+  (Vater N80/Mutter N81) — `_reconstruct_parents` greift dann eine Zeile zu hoch und paart die
+  Mutter des Nachbar-Blocks mit dem echten Vater.
+- **EMF/WMF sind keine Fotos**: Excel legt neben dem Foto teils ein Vektor-Metafile ab; Browser
+  können es nicht darstellen (kaputte Bildkachel in der Akte) → `extract._attach_photos`
+  überspringt `.emf`/`.wmf` (Regressionstest in `test_extract.py`).
+- **Resolution-Schlüssel in `conflict-decisions.json` (Stand 2026-08-19)**: neben
+  `father/mother(+Dob)`, `isResident`, `notes`, `receiver`, `dateOfDeath`, `deceased`,
+  `correctDob`, `renameTo`, `mergeExternalRefs`, `suppressExternalRefs`, `farbschlag` auch
+  **`goHomeDate`** (autoritativ, überschreibt auch einen vorhandenen/kaputten Wert und zieht
+  Status `GivenAway` nach, sofern nicht `Deceased`) und **`spottingType`** (Scheckungsart —
+  der Importer leitet sie aus keiner Quelle ab; `IngestResolvedService` überträgt sie nur,
+  wenn der Payload einen Wert hat, sonst bliebe eine von Hand erfasste Angabe nicht stehen).
+  **`genotype`** gewinnt bei **präzisem** Match (externalRef ODER name+dob) auch gegen einen
+  bereits gefüllten Wert — bei Wurfchronik-Tieren ist der meist nur der Kanon-Fill des
+  Farbschlags; ein name-only-Match füllt weiterhin nur leere Felder (Namensvetter-Schutz).
+- **Pro Tier greift nur EINE Resolution** (first match: externalRef → endswith → name+dob →
+  name-only). Nie einen zweiten Eintrag mit derselben externalRef/demselben (name,dob) anlegen,
+  sondern den bestehenden **in place** erweitern — sonst gewinnt still der letzte und Felder
+  gehen verloren. **Wurfchronik-Jungtiere haben zur Override-Zeit noch kein DOB** (das kommt
+  später aus dem Wurfdatum) → dort ist `externalRef` der einzige zuverlässige Schlüssel.
+- **`renameTo` zieht durch Freitext-Notizen** (`apply_rename_note_sweep`, letzter Schritt vor
+  dem Payload-Dump): der alte Name blieb sonst in Wurf-Notizen stehen („Blacky + Kruke v. …").
+  Wortgenau, mit Guards — Quellname < 4 Zeichen oder > 2 Wörter wird ignoriert, kein Ersetzen,
+  wenn der alte Name im neuen Rufnamen steckt, und Notizen, die die Umbenennung selbst
+  dokumentieren („umbenannt"/„ursprünglich"), bleiben unberührt. Ohne diese Guards trifft der
+  Sweep Abnehmer-Namen und Gewichtsnotizen (im Probelauf 16 von 22 Ersetzungen falsch).
+- **`parse_date` verwirft implausible Jahre** (< 1900 oder > aktuelles Jahr + 1) → `None`;
+  Wurfchronik-Transkriptionen bauen Daten sonst falsch zusammen (JackJack: „1310-05-13").
+- **Sternloses Geburtsdatum in Stammbaum-Charts**: `extract.py` normalisiert Zellen wie
+  `22.08.2019/+09.04.2024` (ohne `*`) zu `*…`, wenn Block-Kontext vorliegt (Genotyp ≤3 Zeilen
+  darunter, Namenszelle ≤3 darüber). Ohne das erkennt die Blockheuristik das Tier nicht und
+  `_reconstruct_parents` greift in den Nachbar-Ast (Ticket 65266679 Bijou).
+- **`renameTo` ist eltern-verknüpfungssicher**: umbenannte Tiere werden im Eltern-Namensindex
+  zusätzlich unter ihrem **Quell-Namen** (`_pre_rename_name`) geführt, sonst verlieren Würfe, die
+  den alten Namen referenzieren, ihren Eltern-Link (Ticket e0a0c304 Kruke→Kuke). `dateOfDeath`
+  ist als Resolution-Override unterstützt (setzt Todesdatum + Status Deceased; rpro3 hat keine
+  Sterbespalte).
+
+## Verifikations-Checkliste vor „fertig"
+
+1. `npx tsc --noEmit`, `npx vitest run`, `npx eslint` sauber.
+2. Betroffene `npx playwright test`-Specs grün.
+3. `dotnet build` + `dotnet test` grün.
+4. Bei Import-Änderungen: `python test_*.py` grün + `resolved_import.json` plausibel
+   (Stichprobe), danach App neu starten + `POST /import/ingest-resolved`.
+
+## Gedächtnis (MemPalace) — IMMER nutzen
+
+Dieses Projekt nutzt **MemPalace** als KI-Langzeitgedächtnis (lokal, kein API-Key).
+Die Anbindung ist im Repo persistiert und lädt automatisch:
+- `.mcp.json` (committet) registriert den MCP-Server `mempalace-mcp` → **19 MCP-Tools**
+  (`mempalace_search`, `mempalace_kg_query/add/invalidate/timeline`, `mempalace_add_drawer`,
+  `mempalace_diary_*` …). Aktiv ab Claude-Neustart (MCP-Server einmal bestätigen).
+- `.claude/settings.json` (committet) verdrahtet die Hooks
+  `mempalace hook run --hook {session-start,stop,precompact} --harness claude-code`:
+  **SessionStart** lädt relevanten Kontext automatisch, **Stop/PreCompact** persistieren.
+- Voraussetzung: `mempalace` ist installiert und auf PATH (`~/.local/bin`). Nach `git clone`
+  ggf. MemPalace installieren; `mempalace.yaml` (Raum-Config) ist bewusst **gitignored**
+  (per-project, lokal). Der Palast selbst liegt lokal unter `~/.mempalace` (nicht im Repo).
+
+**Arbeitsweise pro Session:** zu Aufgabenbeginn relevantes Wissen abrufen
+(`mempalace_search` / `mempalace_kg_query`), bevor du im Code suchst; am Ende neue
+durable Erkenntnisse ablegen.
+
+**Subagenten MÜSSEN MemPalace ebenfalls nutzen** — das im Subagent-Prompt IMMER explizit
+anweisen: zu Aufgabenbeginn den Palast abfragen (am einfachsten per CLI, kein Key nötig:
+`mempalace search "<keywords>"` bzw. `mempalace search "<…>" --wing gerbilmanager`; falls
+MCP-Tools verfügbar auch `mempalace_search`/`mempalace_kg_query`) — relevante Domänenregeln,
+frühere Entscheidungen und Stolperfallen holen, BEVOR im Code gesucht wird; durable
+Erkenntnisse am Ende ablegen (`mempalace add-drawer`/MCP). Gilt für JEDEN gespawnten Agenten.
+
+### Memory-Policy — WANN / WIE / WO eine Memory anlegen
+
+**WANN** (anlegen): nur **dauerhaft** nützliches, **nicht-offensichtliches** Wissen, das
+künftige Sessions braucht — Architektur-/Design-Entscheidungen und ihr *Warum*, Domänenregeln
+(z. B. 6-Jahre-Lebensspanne, Geschwisterverpaarung), Konventionen, Stolperfallen, bestätigte
+Nutzer-Präferenzen, wiederkehrende Workflows.
+**NICHT anlegen**: transienter Task-Status; was Code/Git/CLAUDE.md ohnehin festhalten;
+Dinge, die nur für das aktuelle Gespräch zählen.
+
+**WIE** (anlegen/pflegen):
+- Fakt mit Gültigkeit → `mempalace_kg_add`. Freitext-Notiz/Erkenntnis → `mempalace_add_drawer`
+  (vorher `mempalace_check_duplicate`).
+- Ändert/erledigt sich ein Fakt → `mempalace_kg_invalidate` (setzt End-Datum, **nicht löschen** —
+  der Graph ist temporal). So bleibt nichts veraltet stehen.
+- Repo-Dateien werden über `mempalace mine <dir>` automatisch gefilet; `mempalace sync --apply
+  --wing gerbilmanager` entfernt Drawers gelöschter/verschobener Dateien.
+
+**WO** (welcher Speicher):
+- **MemPalace-Palast** (`~/.mempalace`, lokal): reichhaltiges, durchsuchbares Recall — der Default
+  für Memories.
+- **CLAUDE.md** (Repo, committet): die **kanonischen** Projektfakten/Konventionen, die geteilt und
+  versioniert sein müssen. Wichtige durable Erkenntnisse hier spiegeln, damit sie im Repo (nicht nur
+  lokal) liegen.
+
+Faustregel: durable + projektweit kanonisch → **CLAUDE.md** *und* Palast; sonstiges durable Wissen →
+Palast; veraltetes → invalidieren, nicht stehen lassen.
