+# RetrieX Patch 44 - Runtime Answer Guard / Shop Follow-up Cleanup
+
+## Ziel
+
+Dieser Patch behandelt drei Fehler außerhalb der p43 YAML-/Listen-/Maps-Konsolidierung:
+
+1. Sporadische endlos lange Produktlisten, bei denen ein letztes Shop-Produkt wiederholt wird.
+2. Falscher einleitender Satz bei direkten Zubehör-/Kabel-Shopfragen wie `zeige mir Anschlusskabel für pH/Redox`.
+3. Falsche Shop-Follow-up-Query `schaue` bei `schaue im shop` nach einer vorherigen fachlichen Frage.
+
+## Änderungen
+
+### 1. Runtime-Schutz gegen Endlosantworten
+
+Dateien:
+
+- `src/Agent/AgentRunner.php`
+- `src/Config/AgentRunnerConfig.php`
+- `config/retriex/agent.yaml`
+
+Änderung:
+
+- Neuer konfigurierbarer `final_answer_guard`.
+- Stoppt die finale LLM-Ausgabe, wenn eine Antwort zu lang wird oder dieselbe relevante Antwortzeile zu oft wiederholt wird.
+- Der Guard läuft im finalen Streaming-Pfad und ist generisch: keine Chlor-, Schwimmbad-, Testomat- oder Produkt-Sonderlogik.
+- Bei Abbruch wird ein kurzer Hinweis ausgegeben statt endlos weiterzustreamen.
+
+### 2. Ollama Output-Cap
+
+Dateien:
+
+- `src/Infrastructure/OllamaClient.php`
+- `config/retriex/model.yaml`
+- `config/services.yaml`
+- `src/Config/RetriexEffectiveConfigProvider.php`
+
+Änderung:
+
+- Neuer Parameter `retriex.llm.num_predict: 2048`.
+- Wird als Ollama-Option `num_predict` gesendet.
+- Wichtig für Installationen mit blockierender Ollama-Generierung (`stream=false`), damit Runaway-Ausgaben bereits auf Modellseite begrenzt werden.
+
+### 3. `schaue im shop` als Meta-Shop-Follow-up
+
+Datei:
+
+- `config/retriex/language.yaml`
+
+Änderung:
+
+- Ergänzt zentrale User-Instruction-Terme: `schaue`, `schau`, `schauen`, `nachschauen`.
+- Dadurch wird `schaue im shop` wie `suche im shop` als Meta-Shop-Follow-up behandelt und kann den vorherigen Kontext verwenden, statt die Suchquery `schaue` zu senden.
+
+### 4. Zubehörantwort-Hardening
+
+Datei:
+
+- `config/retriex/prompt.yaml`
+
+Änderung:
+
+- Verstärkt Antwortregeln für direkte Zubehör-/Kabel-Shopfragen.
+- Bei passenden Shop-Treffern soll nicht mit einer fehlenden Hauptgerät-/Messgeräte-Aussage begonnen werden.
+- Das verhindert Sätze wie sinngemäß „kein sicher belegter Testomat für pH-Messung“, wenn der Nutzer Anschlusskabel für pH/Redox angefragt hat.
+
+## Geänderte Dateien
+
+- `config/retriex/agent.yaml`
+- `config/retriex/language.yaml`
+- `config/retriex/model.yaml`
+- `config/retriex/prompt.yaml`
+- `config/services.yaml`
+- `src/Agent/AgentRunner.php`
+- `src/Config/AgentRunnerConfig.php`
+- `src/Config/RetriexEffectiveConfigProvider.php`
+- `src/Infrastructure/OllamaClient.php`
+
+## Lokale Prüfungen
+
+Ausgeführt:
+
+```bash
+php -l src/Agent/AgentRunner.php
+php -l src/Config/AgentRunnerConfig.php
+php -l src/Infrastructure/OllamaClient.php
+php -l src/Config/RetriexEffectiveConfigProvider.php
+python3 -c 'YAML parse check for changed YAML files'
+```
+
+Ergebnis:
+
+- PHP-Syntax der geänderten PHP-Dateien: grün.
+- YAML-Parsing der geänderten YAML-Dateien: grün.
+- Konfigurations-Sanity für `schaue/schau` und `shop`: grün.
+
+Nicht vollständig lokal ausführbar:
+
+```bash
+php bin/console mto:agent:config:validate
+```
+
+Grund: Im entpackten ZIP ist kein `vendor/` enthalten; `bin/console` bricht mit `Dependencies are missing. Try running "composer install".` ab.
+
+## Nach dem Einspielen bitte prüfen
+
+```bash
+bin/console cache:clear
+bin/console mto:agent:config:validate
+bin/console mto:agent:regression:test
+bin/console mto:agent:config:audit-source --details
+bin/console mto:agent:config:audit-patterns --details
+```
+
+## Manuelle Regressionen
+
+1. `ich würde gern chlor im schwinnbad messen`
+   - Erwartung: keine endlose Wiederholung des letzten Produkts.
+   - Falls das Modell trotzdem wiederholt, muss die Antwort durch den Guard abbrechen.
+
+2. `zeige mir Anschlusskabel für pH/Redox`
+   - Erwartung: Zubehör-/Kabeltreffer direkt listen.
+   - Kein einleitender Satz über fehlenden Testomat oder fehlendes pH-Messgerät.
+
+3. Dialog:
+   - `welche indikatoren gibt es für die messung von freiem chlor`
+   - danach: `schaue im shop`
+   - Erwartung: Shop-Follow-up nutzt den vorherigen Kontext, nicht die Query `schaue`.
+
+## Hinweise
+
+- Keine Retrieval-, Ranking- oder Produktmatching-Logik wurde geändert.
+- Keine neuen fachlichen Token-/Produktlisten im PHP-Core.
+- Neue fachliche/sprachliche Begriffe liegen in YAML.
+- Der Runtime-Guard ist bewusst generisch und konfigurierbar.
