+# Autonomous Research
+
+## Ziel
+
+Autonomous Research entkoppelt die Webrecherche von einem einzelnen AI-THINK-Artikelversuch. Das Brain kann nun selbstständig Wissenslücken erkennen, persistente Rechercheaufgaben planen, sie mit niedriger Priorität über den vorhandenen Ollama-Pool abarbeiten und akzeptierte externe Evidenz sofort lernen und verknüpfen.
+
+Produktive Knowledgebase-Dateien werden weiterhin niemals automatisch verändert. Ein belastbarer neuer oder überarbeiteter Artikel landet ausschließlich im AI-Staging.
+
+## Warum eine eigene asynchrone Queue vor Ollama
+
+Die Aufgaben werden nicht blind direkt in eine einzelne Ollama-Instanz geschoben. Davor liegt eine persistente SQLite-Queue:
+
+```text
+Graph-Scanner / API / Agent-Event
+            ↓
+research_tasks in graph.db
+            ↓
+Leerlauf-, Tagesbudget- und Prioritätsprüfung
+            ↓
+Lease für genau einen Worker
+            ↓
+vorhandener Ollama-Pool mit Healthcheck, least-inflight und Failover
+            ↓
+SearXNG, Volltextprüfung, Evidenzlernen und Artikelsynthese
+```
+
+Das ist sinnvoller als eine unkontrollierte Ollama-Queue:
+
+- Benutzeranfragen und normales AI-THINK behalten Vorrang.
+- Aufgaben überleben Prozess- und Host-Neustarts.
+- Doppelte Themen werden über einen stabilen Dedupe-Key und einen Cooldown verhindert.
+- Eine Worker-Lease verhindert doppelte Verarbeitung.
+- Fehlgeschlagene Aufgaben werden mit Backoff erneut eingeplant und nach `max_attempts` beendet.
+- Der Ollama-Pool entscheidet erst unmittelbar vor einem Modellaufruf, welcher gesunde Node Kapazität besitzt.
+- Autonome Aufrufe tragen einen Low-Priority-Kontext. Wartet eine normale Agent-, Query- oder AI-THINK-Anfrage, darf der Hintergrundworker beim nächsten Pool-Acquire nicht vorbeiziehen.
+
+Bereits laufende Modellgenerierungen werden nicht hart abgebrochen. Auf einem einzelnen Ollama-Node kann eine neu eintreffende interaktive Anfrage daher noch den aktuell laufenden autonomen Modellaufruf abwarten; zwischen allen weiteren Modellaufrufen erhält sie Vorrang. In einem Multi-Node-Pool kann sie parallel einen freien Node erhalten.
+
+Der autonome Worker selbst arbeitet absichtlich sequenziell. SearXNG-Abfragen und Seitenabrufe können innerhalb einer Aufgabe mehrere Quellen verarbeiten, aber nur eine autonome Wissensaufgabe darf gleichzeitig die Synthese- und Graphpipeline verändern.
+
+## Eigenantrieb
+
+Ein periodischer Scanner bewertet produktive Wissens-Nodes innerhalb des exakten Thinking-Source-Filters. Signale sind unter anderem:
+
+- akzeptierte `contradicts`-Beziehungen;
+- keine gelernte externe Evidenz;
+- hohes Alter des Wissens;
+- hohe Zentralität im Graphen;
+- schwache Verknüpfung eines ansonsten produktiven Wissenspunkts.
+
+Die besten Kandidaten werden von Qwen in konkrete Opportunities umgewandelt. Der Planner muss dabei aus dem vorhandenen Quellenkontext ableiten:
+
+- ob externe Recherche wirklich Mehrwert verspricht;
+- ein enges Thema;
+- eine Begründung;
+- eine Priorität von 0 bis 1;
+- konkrete Forschungsfragen;
+- präzise deutsche und englische SearXNG-Queries;
+- ausschließlich tatsächlich vorhandene Seed-Node-IDs.
+
+Eine Opportunity unterhalb der im WebUI eingestellten Mindestpriorität wird nicht eingereiht.
+
+## Nutzungsgesteuerte Trigger
+
+Eine normale Wissensanfrage erzeugt optional eine Aufgabe, wenn keine Treffer vorhanden sind oder die Antwort explizite Unsicherheiten enthält. Das Verhalten wird durch folgende Einstellung gesteuert:
+
+```env
+BRAIN_AUTONOMOUS_RESEARCH_QUERY_TRIGGERS=true
+```
+
+Zusätzlich erzeugen diese externen Eventtypen automatisch eine Research-Aufgabe:
+
+```text
+knowledge.answer_insufficient
+knowledge.search.empty
+agent.answer.uncertain
+```
+
+Beispiel:
+
+```bash
+curl -X POST http://localhost:8090/api/events \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "type": "knowledge.answer_insufficient",
+    "source": "glpi-ai-agent",
+    "query": "Wie wird ein verschlüsselter ZFS-Datensatz auf einem Ersatzsystem wiederhergestellt?",
+    "message": "Die vorhandenen Treffer enthalten keine Key-Import- und Validierungsschritte.",
+    "hits": [],
+    "metadata": {"priority": 0.95}
+  }'
+```
+
+## Direkte API-Trigger
+
+### Aufgabe einreihen
+
+```http
+POST /api/research/tasks
+```
+
+```json
+{
+  "topic": "ZFS-Schlüsselwiederherstellung",
+  "question": "Wie werden verschlüsselte ZFS-Datasets auf einem Ersatzsystem importiert, entsperrt und validiert?",
+  "seed_node_ids": ["optional-existing-node-id"],
+  "priority": 0.95,
+  "requested_by": "glpi-ai-agent",
+  "reason": "knowledge.answer_insufficient"
+}
+```
+
+Die Antwort ist `202 Accepted`, wenn eine neue Aufgabe erstellt wurde. Liegt dasselbe Thema innerhalb des Cooldowns bereits vor, wird die bestehende Aufgabe mit `200 OK` zurückgegeben.
+
+### Queue anzeigen
+
+```http
+GET /api/research/tasks?limit=100
+```
+
+### Aufgabe abbrechen
+
+```http
+POST /api/research/tasks/{id}/cancel
+```
+
+Nur `queued`, `deferred` und `reserved` können abgebrochen werden. Eine bereits laufende Synthese wird nicht hart unterbrochen.
+
+### Graph sofort analysieren
+
+```http
+POST /api/research/autonomous/scan
+```
+
+### Wartende Queue sofort wecken
+
+```http
+POST /api/research/autonomous/run
+```
+
+„Queue starten“ umgeht weder Leerlauf-, Thinking-, SearXNG-, Tagesbudget- noch Ollama-Kapazitätsregeln. Es verkürzt nur die Wartezeit bis zur nächsten Prüfung.
+
+## Verarbeitung einer Aufgabe
+
+1. Vorhandene Seed-Nodes werden gegen den exakten Thinking-Source-Filter geprüft.
+2. Fehlen Seeds, sucht EmbeddingGemma passende produktive Wissens-Nodes zum Thema.
+3. Qwen vervollständigt bei Bedarf Forschungsfragen und deutsche/englische Queries.
+4. Die bestehende iterative Research-Pipeline führt SearXNG-Suchen aus.
+5. Treffer passieren Snippet-, Domain-, Relevanz- und Quellenqualitäts-Gates.
+6. Die besten Seiten werden SSRF-geschützt geladen, bereinigt und erneut bewertet.
+7. Nur akzeptierte Volltextbelege werden als Research-Evidence gelernt und mit Seed-Nodes verbunden.
+8. Die vorhandene Knowledge-Synthesis entscheidet, ob Evidenz allein genügt oder ein neuer beziehungsweise aktualisierter KB-Entwurf echten Mehrwert bietet.
+9. Resultat, Evidenzanzahl, Artikelpfad und Versuchshistorie werden in SQLite gespeichert.
+
+Mögliche Outcomes:
+
+```text
+evidence_only
+article_created
+no_useful_evidence
+failed
+```
+
+## Queue-Zustände
+
+```text
+queued     wartet auf Priorität, Budget und Leerlauf
+reserved   Worker-Lease wurde vergeben
+running    SearXNG/Ollama/Synthese läuft
+deferred   temporärer Fehler; erneuter Versuch nach Backoff
+completed  Aufgabe ist abgeschlossen
+failed     maximale Versuche erreicht
+cancelled  manuell verworfen
+```
+
+Beim Start setzt das Brain abgelaufene `reserved`- oder `running`-Leases automatisch auf `deferred` zurück.

+Der linke Activity-Feed zeigt Opportunity-Scans, Einreihung, Start, Abschluss und Fehler. Die darunterliegende SearXNG- und Volltextanimation bleibt unverändert sichtbar.
+
+## Source-Filter
+
+Der autonome Graphscanner und die Seed-Auswahl verwenden den exakten Thinking-Source-Filter. Externe Volltextbelege besitzen als `source` ihre Domain. Soll autonome Recherche neue Domains uneingeschränkt lernen dürfen, muss **Thinking → Alle** aktiv sein. Eine eng begrenzte Thinking-Source-Liste verwirft Webbelege, deren Domain nicht exakt ausgewählt ist.

+## Autonomous Research: selbstständige Wissensanreicherung
+
+Die Webrecherche ist nicht mehr an einen einzelnen AI-THINK-Artikelversuch gebunden. Ein eigener Opportunity-Scanner bewertet den Graphen regelmäßig auf Widersprüche, fehlende externe Evidenz, Alter, Zentralität und schwache Verknüpfung. Qwen zerlegt geeignete Kandidaten in konkrete Forschungsfragen sowie deutsche und englische SearXNG-Queries.
+
+Aufgaben landen zuerst persistent in `graph.db`. Ein Low-Priority-Worker least genau eine Aufgabe, prüft Leerlauf, Tagesbudget und freie Kapazität im Ollama-Pool und verwendet danach die bestehende iterative SearXNG-/Volltext-/Evidenzpipeline. Das ist bewusst keine unkontrollierte zweite Ollama-Queue: Benutzeranfragen und normales AI-THINK behalten Vorrang, Aufgaben überleben Neustarts, werden dedupliziert und nach temporären Fehlern mit Backoff wiederholt. Der Ollama-Pool kennt zusätzlich normale und Low-Priority-Waiter; autonome Modellaufrufe dürfen bei der nächsten Node-Zuteilung keine wartende interaktive Anfrage überholen.

+Der Agent oder andere Systeme können über `POST /api/research/tasks` explizit Aufgaben einreihen. Die Eventtypen `knowledge.answer_insufficient`, `knowledge.search.empty` und `agent.answer.uncertain` erzeugen über `/api/events` ebenfalls eine priorisierte Aufgabe. Die WebUI zeigt Queue, Status, Evidenzzahl und Versuche und bietet manuelles Einreihen, Graphanalyse, Queue-Wakeup sowie Abbruch wartender Aufgaben.
+Die aktualisierten Integrationspatches unter `integrations/agent/` und `integrations/knowledgebase/` senden bei einer Suche ohne Treffer automatisch `knowledge.search.empty`; die Telemetrie bleibt asynchron und fail-open.

+# Validation: Autonomous Research
+
+## Durchgeführt
+
+- `node --check internal/web/static/app.js`
+- YAML-Parsing von `docker-compose.yml` und `deployment/docker-compose.full.yml`
+- vollständige Go-Typkompilierung aller Pakete
+- `go vet ./...`
+- statischer Linux-amd64-Buildpfad
+- Config-Tests für alle Autonomous-Research-Variablen und fehlendes `SEARXNG_URL`
+- Unit-Tests für Graph-Opportunity-Priorisierung, exakte Thinking-Source-Filter, DE/EN-Queryplanung, Runden und stabile Deduplizierung
+- Ollama-Pool-Test: Low-Priority-Waiter darf einen bereits wartenden Normal-Priority-Aufruf nicht überholen
+- JavaScript-/HTML-ID-Abgleich für alle neuen WebUI-Bedienelemente
+- Parsing der aktualisierten Agent- und Knowledgebase-Integrationspatches mit `git apply --stat`
+- SQL-Lifecycle mit SQLite: Schema, 26-spaltiger Insert, Lease, `reserved → running → completed`, Attempt-Historie und Foreign Keys
+- Kontrolle, dass `go.mod` ausschließlich `modernc.org/sqlite v1.37.1` verwendet und kein Test-Replace ausgeliefert wird
+
+## Einschränkung der Buildumgebung
+
+Der Zugriff auf `proxy.golang.org` war in der Ausführungsumgebung durch DNS-/Netzwerkregeln blockiert. Der echte `modernc.org/sqlite`-Modulcode konnte deshalb hier nicht erneut heruntergeladen und ausgeführt werden.
+
+Für Typkompilierung, `go vet` und den statischen Build wurde ausschließlich temporär außerhalb des Projekts ein API-kompatibler Compile-Stub verwendet. `go.mod` und `go.sum` wurden anschließend unverändert wiederhergestellt. Das ausgelieferte Projekt enthält keinen Stub und keinen `replace`-Eintrag.
+
+Die SQL-Statements der neuen Queue wurden zusätzlich mit der lokalen SQLite-Laufzeit von Python ausgeführt. Auf dem Zielsystem sollte nach dem Entpacken abschließend ausgeführt werden:
+
+```bash
+go test ./...
+go vet ./...
+docker compose up -d --build --force-recreate brain
+```
+
+## Erwartete Runtime-Prüfung
+
+```bash
+curl -s http://localhost:8090/api/status | jq '.autonomous_research, .ollama_pool | {autonomous_research: .autonomous_research, ollama_pool: .ollama_pool}'
+curl -s http://localhost:8090/api/research/tasks | jq
+```
+
+In `ollama_pool` werden zusätzlich `normal_waiters` und `low_priority_waiters` gemeldet.
