-+# RetrieX Patch p87 - Chat Frontend Symfony Controller
-+
-+## Zweck
-+
-+Der Chat lief bisher als statische `public/index.html`. Dadurch konnte die Startseite den Symfony-Kernel umgehen und war fuer spaetere PHP-seitige Erweiterungen wie Rollen-/Rechtepruefung, Mandantenlogik oder dynamische Chat-Optionen ungeeignet.
-+
-+p87 hebt nur den Chat-Frontend-Einstieg in einen eigenen Symfony-Controller und trennt ihn architektonisch vom Adminbereich. Es gibt keine Aenderungen an Agent, Retrieval, Scoring, Ranking, Shop-Matching, SSE, History oder Frontend-JavaScript-Logik.
-+
-+## Aenderungen
-+
-+- Neuer Controller: `src/Controller/Chat/ChatController.php`
-+  - Namespace bewusst getrennt von `App\Controller\Admin`
-+  - Route `/` als Chat-Startseite
-+  - Route `/chat` als expliziter Chat-Alias
-+  - rendert `templates/chat/index.html.twig`
-+- Neues Twig-Template: `templates/chat/index.html.twig`
-+  - Inhalt aus der bisherigen `public/index.html` uebernommen
-+  - Asset-Pfade ueber `asset()` gerendert
-+  - Chat-UI bleibt optisch und funktional gleich
-+- `public/index.html` entfernt
-+  - wichtig, damit der Webserver die Root-Anfrage nicht weiter statisch vor Symfony abfaengt
-+- `src/Controller/Admin/DashboardController.php` angepasst
-+  - Root-Routen `''` und `/` entfernt
-+  - Admin-Redirect bleibt nur unter `/admin` und `/admin/`
-+
-+## Architekturentscheidung
-+
-+Chat und Admin bleiben getrennt:
-+
-+- Chat: `App\Controller\Chat\...`, `templates/chat/...`, oeffentliche Route `/` bzw. `/chat`
-+- Admin: `App\Controller\Admin\...`, `templates/admin/...`, geschuetzte Route `/admin...`
-+
-+Damit kann Schritt 2 spaeter sauber aufsetzen, z. B. mit einem eigenen Chat-Firewall-/Access-Control-Bereich oder Controller-Attributen wie `#[IsGranted(...)]`, ohne Admin-Templates, Admin-Routen oder Admin-Navigation mit dem Chat zu vermischen.
-+
-+## Bewusst nicht geaendert
-+
-+- Keine Rollen-/Rechtepflicht fuer den Chat in diesem Patch
-+- Keine Aenderung an `security.yaml`, ausser dass die bestehende Trennung weiterhin moeglich bleibt
-+- Keine Aenderung an `/ask-jobs`, `/ask-sse`, `/history`, `/chat-messages/frontend`
-+- Keine Aenderung an `public/assets/js/base.js`
-+- Keine Aenderung an RAG-/Commerce-/Prompt-/YAML-Logik
-+
-+## Lokale Checks
-+
-+Ausgefuehrt:
-+
-+```bash
-+php -l src/Controller/Chat/ChatController.php
-+php -l src/Controller/Admin/DashboardController.php
-+python3 - <<'PY'
-+from pathlib import Path
-+assert Path('templates/chat/index.html.twig').exists()
-+assert not Path('public/index.html').exists()
-+assert "#[Route('/', name: 'chat_index'" in Path('src/Controller/Chat/ChatController.php').read_text()
-+print('p87 structural checks OK')
-+PY
-+```
-+
-+Ergebnis:
-+
-+- PHP lint OK
-+- Chat-Template vorhanden
-+- statische `public/index.html` entfernt
-+- Root-Route liegt jetzt beim ChatController
-+
-+## Noch in Zielumgebung ausfuehren
-+
-+```bash
-+php bin/console cache:clear
-+php bin/console debug:router | grep -E 'chat_index|admin_dashboard'
-+php bin/console mto:agent:config:validate
-+php bin/console mto:agent:regression:test
-+php bin/console mto:agent:config:audit-source --details
-+php bin/console mto:agent:config:audit-patterns --details
-+```
-+
-+Manuelle Smoke-Tests:
-+
-+1. `/` oeffnet den Chat.
-+2. `/chat` oeffnet denselben Chat.
-+3. `/admin` leitet weiterhin zum Admin-Dashboard/Login.
-+4. `/ask-jobs`, `/ask-sse/{jobId}`, `/history`, `/history/delete`, `/chat-messages/frontend` funktionieren unveraendert.
