+Diese Datei ist die kurze Arbeitsanweisung für Menschen und kleine Coding-Modelle.
+
+## Reihenfolge
+
+1. `README.md` lesen.
+2. Für Verhaltenslogik `docs/BEHAVIOR_ENGINE.md` lesen.
+3. Für Fehler `docs/DEBUGGING.md` abarbeiten.
+4. Für HA-Automationen `docs/CONTROL_HANDOFF.md` lesen.
+5. Vor Release oder Live-Update `docs/OPERATIONS.md` vollständig abarbeiten.
+
+## Verbindliche Regeln
+
+- Erst Zustand und Logs prüfen, dann Ursache formulieren, dann ändern.
+- Keine Annahme als Fakt darstellen.
+- Vor Live-Änderungen Backup oder klaren Rollback-Punkt erstellen.
+- Bestehende Nutzeränderungen nicht zurücksetzen.
+- Kleine, fokussierte Änderungen mit passenden Tests.
+- Eigene SillyHome-Schaltungen niemals als neues Nutzerverhalten lernen.
+- Ein Aktor darf nicht unbeabsichtigt ohne Steuerung bleiben:
+  - SillyHome aktiv: passende HA-Automation darf pausiert sein.
+  - SillyHome Shadow: HA-Automation muss auf Wunsch fortgesetzt werden können.
+- Keine Secrets in Code, Dokumentation, Commits oder Logs.
+
+## Pflichtprüfung
+
+```bash
+.venv/bin/pytest -q
+.venv/bin/ruff check .
+.venv/bin/mypy app backend tests
+git diff --check
+```
+
+## Versionsstellen
+
+Bei jedem Release dieselbe Version setzen:
+
+- `pyproject.toml`
+- `addon/config.yaml`
+- `app/main.py`
+- `CHANGELOG.md`
+
+Danach prüfen:
+
+```bash
+grep -R 'version.*0\\.7\\.0' -n pyproject.toml addon/config.yaml app/main.py
+```
+
+Die konkrete Zielversion im Befehl anpassen.

 # SillyHome Next — Architekturübersicht

-Ziel ist ein lokales, datensparsames, erklärbares Smart-Home-Intelligenzsystem für Home Assistant. Es analysiert Historie, erkennt Gewohnheiten, erstellt Vorhersagen, empfiehlt Automationen und kann auf Wunsch einfach in Automationen übersetzen. Vier Intelligenzebenen sind vorgesehen: regelbasiert, ML-gestützt, LLM-unterstützt und autonomer Hausagent.
+Ziel ist ein lokales, datensparsames und erklärbares Smart-Home-Intelligenzsystem
+für Home Assistant. Nutzer wählen ausschließlich erlaubte Aktoren. Das System
+ordnet Kontext automatisch zu, erkennt historische Nutzerhandlungen, trainiert
+pro Aktor ein Verhaltensmodell und trifft zunächst nur Shadow-Vorhersagen.
+Autonomes Schalten wird separat pro Aktor freigegeben.

 ## Leitentscheidungen

 - Lokal-first und datensparsam; keine Cloudpflicht.
- Trennung von Datenintegration, Trainingspipeline, Vorhersageservice und Erklärungsschicht.
- Standardintegration über MQTT und Home Assistant WebSocket plus REST.
- Schnittstellen über FastAPI und OpenAI-kompatible Endpunkte.
- Langzeitdaten in PostgreSQL und TimescaleDB; Vektoren für semantische Suche optional.
- Deployment über Docker Compose; Kubernetes optional für erweiterte Betriebsgrößen.
+- Trennung von Datenintegration, Kontextzuordnung, Verhaltenslernen,
+  Vorhersage und Aktorausführung.
+- Logbook-basierte Herkunftserkennung; eindeutig erkannte HA-Automationen
+  zählen wie manuelle Bedienungen. Eigene SillyHome-Schaltungen werden nicht
+  zurückgelernt.
+- Ausführung nur für freigegebene, reversible Domains und Zustände sowie mit
+  Konfidenzschwelle und zustandsbezogenem Cooldown.
+- Eindeutig passende HA-Automationen können bei einer SillyHome-Übernahme
+  pausiert und beim Rückfall in den Shadow-Modus wieder fortgesetzt werden.
+- Standardintegration über die lokale Home-Assistant-REST-API.
+- Persistenz als atomische lokale Modell- und Aktorartefakte.
+- Deployment als Home-Assistant-Add-on oder über Docker Compose.
 - Tests, Docs und Changelog sind Pflichtbestandteil jeder Änderung.

 # Changelog

-## Unreleased
+## 0.7.17 - 2026-06-16
+- WebSocket-Eventpfad ist schneller: irrelevante HA-State-Changes werden vor
+  dem teuren State-Cache-Listenbau verworfen.
+- WebSocket nutzt Keepalive und reconnectet nach Abbrüchen nach 1s statt 5s.
+
+## 0.7.16 - 2026-06-16
+- Beobachtete Aktoren werden in der Übersicht nach Raum oder Typ gruppiert und
+  mit Friendly Name angezeigt.
+
+## 0.7.15 - 2026-06-16
+- Add-on-Start ist robust gegen Home-Assistant-Core-502 beim Systemboot:
+  API und WebSocket-Listener starten trotzdem, Reconciliation/Training werden
+  im Hintergrund mit Retry nachgeholt.
+- Periodische Reconciliation und Fallback-Auswertung beenden den Dienst nicht
+  mehr bei temporären HA-Fehlern.
+- Add-on-Watchdog prüft `/health`, damit Supervisor den Dienst nach Absturz
+  wieder starten kann.
+
+## 0.7.14 - 2026-06-16
+- Onboarding-Vorschläge laden im Dashboard nachgelagert, damit Status,
+  Aktor-Auswahl und bestehende Geräte nicht auf Automation-Discovery warten.
+
+## 0.7.13 - 2026-06-16
+- Diagnose-/Schutzsensoren wie Überhitzung und Überlast werden nicht mehr nur
+  wegen gleicher Strom-/Monitoring-Bereiche automatisch als Lichtkontext
+  übernommen.
+- Verwendete Kontext-Entities können pro Aktor direkt entfernt und damit als
+  manuelle Zuordnung überschrieben werden.
+- Onboarding-Vorschläge zeigen passende, noch nicht eingerichtete Aktoren aus
+  bestehenden Automationen und naheliegenden Kontexten.
+- TV-/Medien-Aktoren über `media_player` und Fernbedienungen über `remote`
+  werden in Discovery und Auswahl berücksichtigt.
+
+## 0.7.12 - 2026-06-16
+- Aktor-Auswahlliste zeigt maximal 50 Treffer gleichzeitig und fordert bei
+  größeren Mengen zum Eingrenzen per Suche oder Typfilter auf.
+
+## 0.7.11 - 2026-06-16
+- Aktor-Discovery erkennt weitere steuerbare HA-Domains wie Buttons, Helper,
+  Heizungen, Schlösser, Ventile und numerische Helper.
+- Aktor-Auswahl dedupliziert Licht-/Schalter-Doppelungen pro Gerät und gruppiert
+  zusätzliche Typen im Dashboard.
+- Discovery liefert Kategorien für Mess-, Binär-, Kontext- und Aktor-Entities.
+- Nutzerfeedback kann Vorhersagen als korrekt oder falsch markieren und direkt
+  als Lernsignal speichern.
+
+## 0.7.10 - 2026-06-16
+- WebSocket-State-Changes aktualisieren einen internen Home-Assistant-State-
+  Cache und werten Aktoren direkt gegen diesen frischen Event-Zustand aus.
+- Event-Auswertungen lösen keine REST-Statusabfrage mehr aus, bevor sie
+  aktive Aktoren schalten.
+
+## 0.7.9 - 2026-06-15
+- Event-basierte Vorhersagen verwenden den frischen Sensorzustand direkt aus
+  dem Home-Assistant-WebSocket-Event, damit Kontextwechsel ohne REST-Race sofort
+  bewertet und geschaltet werden können
+- Regressionstest stellt sicher, dass ein Türsensor-Event trotz veraltetem
+  HA-Snapshot direkt `light.turn_on` auslöst
+
+## 0.7.8 - 2026-06-15
+- Home-Assistant-WebSocket-Listener deaktiviert den clientseitigen Keepalive-
+  Ping, damit stabile HA-Verbindungen nicht durch Ping-Timeouts ständig neu
+  aufgebaut werden
+- Fallback-Auswertung läuft bei getrenntem WebSocket kurzfristig alle 5 Sekunden,
+  damit übernommene Aktoren nicht ohne Steuerung bleiben
+
+## 0.7.7 - 2026-06-15
+- WebSocket-State-Changes lesen jetzt das echte Home-Assistant-Eventformat
+  (`event.data.entity_id`), damit Kontextwechsel wie Türsensoren sofort
+  Vorhersagen und Schaltungen auslösen statt erst beim nächsten Statusabruf
+
+## 0.7.6 - 2026-06-14
+- Kontextvorschläge blenden zusätzlich Batterie-, Status-, Node-, Last-Seen-
+  und Basic-Entities aus, sofern sie nicht bewusst manuell ausgewählt wurden
+
+## 0.7.5 - 2026-06-14
+- Kontextvorschläge weiter geschärft: Standardliste zeigt nur gleiche Räume,
+  gemeinsame Geräte/Tokens oder echte globale Außenwerte
+- Diagnosewerte wie MQTT-, WiFi-, Restart- und Connect-Zähler werden nicht mehr
+  als fachliche Kontextvorschläge angeboten
+
+## 0.7.4 - 2026-06-14
+- Kontext-Auswahl liefert jetzt aktorbezogene Vorschläge statt einer pauschalen
+  Roh-Liste aller Sensoren und Zustände
+- Dashboard-Auswahl für Aktoren und Kontext nach Typ/Kategorie gruppiert und
+  durchsuchbar; lange Listen werden begrenzt statt mobil unbedienbar zu werden
+- Manuelle Entity-ID-Eingabe ergänzt, damit relevante Sensoren auch ohne
+  Dropdown-Treffer gespeichert werden können
+- Irrelevante System-/VPN-/pfSense-Sensoren tauchen bei Lichtaktoren ohne
+  fachlichen Bezug nicht mehr als Standardvorschläge auf
+
+## 0.7.3 - 2026-06-14
+- Automatische Kontextzuordnung ignoriert generische Bereiche wie `Monitoring`,
+  damit System-/Disk-/Überhitzungssensoren nicht fälschlich Lichtaktoren erklären
+- Aktor-Auswahl auf tatsächlich sicher steuerbare Domains begrenzt:
+  `light`, `switch`, `cover`, `fan`, `humidifier`
+- Neue manuelle Kontext-Zuordnung pro Aktor: Haupt-Messsensor optional setzen und
+  mehrere relevante Kontext-Entities wie PIR, Außenhelligkeit, Luftfeuchtigkeit
+  oder andere Lichtzustände auswählen
+- Dashboard-Dropdown durch echtes Select plus Suche ersetzt; mobile Bedienung und
+  Aktor-Details enthalten Speichern/Neu-laden-Aktionen für manuelle Kontextwahl
+
+## 0.7.2 - 2026-06-14
+- Home-Assistant-Entity-Metadaten werden in Batches gelesen, damit große HA-
+  Installationen nicht mehr am Template-Ausgabe-Limit scheitern
+- Nicht über die HA-Config-API exponierte Automationen werden leise übersprungen,
+  statt wiederholt Warnungen in die Logs zu schreiben
+- Dashboard für mobile Nutzung optimiert: Sticky-Schnellnavigation, Karten statt
+  breiter Tabelle, größere Touch-Ziele und bessere Detail-/Menüführung
+- WebSocket-Status ist direkt im Dashboard-Systemstatus sichtbar
+
+## 0.7.1 - 2026-06-14
+- Event-basierter Home-Assistant-WebSocket-Listener authentifiziert sich jetzt
+  mit dem echten HA-WebSocket-Protokoll (`auth_required` -> `auth` -> `auth_ok`)
+- Kompatibilität mit aktuellen `websockets`-Versionen wiederhergestellt
+- WebSocket-Healthcheck und Event-Listener-Tests laufen ohne zusätzliches
+  Async-Pytest-Plugin
+- Add-on-Version angehoben, damit Home Assistant das aktualisierte Image baut
+
+## 0.7.0 - 2026-06-14
+- Freie Eingabe von Home-Assistant-Entitätsnamen mit Vorschlagsliste
+- Freigabestatus und Blockadegrund sind in Übersicht und Details immer sichtbar
+- Vorhersagen erklären konkret, warum sie ausgeführt oder nicht ausgeführt wurden
+- Cooldown blockiert nur Wiederholungen desselben Zielzustands; Gegenaktionen
+  wie `Licht an` gefolgt von `Licht aus` bleiben sofort möglich
+- Passende HA-Automationen werden aus ihren echten Konfigurationen erkannt und
+  können pausiert oder fortgesetzt werden
+- Sichere Steuerungsübergabe: SillyHome kann übernehmen und passende
+  HA-Automationen pausieren; beim Stoppen können sie gezielt fortgesetzt werden
+- Dashboard wird ohne Browser-Cache ausgeliefert
+- Reproduzierbare Runbooks für Debugging, Berechnung, Entwicklung, Tests,
+  Release, Add-on-Update, Live-Verifikation und Rollback
+
+## 0.6.2 - 2026-06-14
+- Eindeutig im Home-Assistant-Logbuch erkannte Automationen und Scripts zählen für
+  Lernen und Freigabe gleichwertig wie manuelle Bedienungen
+- Automationsmuster erhalten dieselbe Modellgewichtung wie manuelle Handlungen
+- Oberfläche zeigt die gemeinsame Zahl als `eindeutig geregelt`; eine
+  ausdrückliche Aktivierung pro Aktor bleibt weiterhin erforderlich
+
+## 0.6.1 - 2026-06-14
+- Manuelle Prüfung als `Aktuelle Situation auswerten` eindeutig von Simulation
+  oder Aktorschaltung abgegrenzt
+- Sichtbare Rückmeldung mit Prüfzeitpunkt, vorhergesagtem Zustand und Sicherheit
+  oder klarem Hinweis auf einen fehlenden frischen Sensorwechsel
+
+## 0.6.0 - 2026-06-14
+- Kausales Shadow-Lernen erkennt frische Kontextwechsel unmittelbar vor einer
+  Aktorhandlung, etwa `Tür geschlossen → offen` vor `Licht aus → an`
+- Historische Home-Assistant-Automationen dürfen Vorhersagen begründen, zählen
+  aber weiterhin niemals als eindeutige Benutzerhandlung oder Ausführungsfreigabe
+- Aktuelle `last_changed`-Zeitpunkte verhindern Vorhersagen aus längst
+  unveränderten Sensorzuständen
+- Oberfläche trennt gelernte Benutzerhandlungen und erkannte HA-Automationen
+
+## 0.5.4 - 2026-06-14
+- Tür-, Bewegungs- und andere belastbare Kontextsensoren werden auch ohne
+  numerischen Sensor als vollständige automatische Kontextzuordnung angezeigt
+- Status und Zuordnungssicherheit bilden das aktive Verhaltenslernen ab statt
+  eines optionalen numerischen Modells
+- Ausführungsfreigabe erscheint erst, wenn genügend eindeutig manuelle
+  Bedienungen vorliegen; bis dahin nennt die Oberfläche die noch fehlende Anzahl
+
+## 0.5.3 - 2026-06-14
+- Verhindert fachlich falsche Sensorzuordnungen nur aufgrund generischer Namen wie
+  `Licht` oder `Lichtschalter`
+- Übernimmt numerische Sensoren nur noch bei einem belastbaren absoluten Score und
+  einer eindeutigen Abgrenzung zum zweitbesten Kandidaten
+- Begrenzt Zusatzkontext auf relevante Sensoren und bevorzugt bei Lichtaktoren
+  echte Beleuchtungsstärke gegenüber fremden Leistungs- oder Energiezählern
+
+## 0.5.2 - 2026-06-14
+- Add-on-Build invalidiert den Docker-Cache bei jeder Versionsänderung, damit
+  Versionsmetadaten und tatsächlich ausgelieferter Anwendungscode übereinstimmen
+- Korrigierte Ingress-Oberfläche aus 0.5.1 dadurch erstmals zuverlässig ausgeliefert
+
+## 0.5.1 - 2026-06-14
+- Technische Modell-, Intervall- und Sicherheitsparameter aus der normalen
+  Home-Assistant-Add-on-Konfiguration entfernt; sichere Standardwerte bleiben aktiv
+- Ingress um einen klaren Ablauf mit Aktorauswahl, Beobachtungsphase und späterer
+  Ausführungsfreigabe ergänzt
+- Bedienelemente und Diagnosen in verständlicher Alltagssprache erklärt
+
+## 0.5.0 - 2026-06-14
+- Ingress auf reine Aktorauswahl, automatischen Lernstatus und Vorhersagen reduziert
+- Automatische Kontextzuordnung ohne Sensor-Overrides oder Review-Blockade
+- Historische Handlungserkennung aus HA-State-History und Logbook-Herkunft
+- Persistentes Verhaltensmodell pro Aktor mit Zeit-, Wochentags- und Kontextmustern
+- Shadow-Vorhersagen vor jeder Ausführungsfreigabe
+- Explizite Aktivierung pro Aktor, Konfidenzschwelle, Cooldown und enge Service-Whitelist
+- Schutz vor dem Lernen erkannter HA-Automationen und eigener Schaltvorgänge
+- Automation-Proposal- und Override-Endpunkte aus dem aktiven Produkt entfernt
+
+## 0.4.0 - 2026-06-13
+- Aktuator-zentrierte Einrichtung: Nutzer wählen nur noch Aktuatoren, Sensoren werden deterministisch gefunden und bewertet
+- Persistente automatische und manuelle Sensorzuordnungen mit Evidenz, Confidence, Review-Gating und Neustart-Sicherheit
+- Autonomer Modell-Lebenszyklus auf echter HA-Historie: Training, Retraining bei Staleness oder Datenänderung, Archivierung von Waisen
+- Neues Dashboard und API für Aktuatorauswahl, Reconciliation, Overrides, Modellstatus und Audit-Trail
+- Neue Container-/Add-on-Defaults für Aktuator-Store und periodische Reconciliation ohne zusätzliche Gerätesteuerung
+
+## 0.2.0 - 2026-06-13
+- Klassifizierte Home-Assistant-Entity-Discovery mit Lernrelevanz und Filtern
+- Validierter Zugriff auf die Home-Assistant-History-API
+- Normalisierte, chronologisch sortierte numerische Zeitreihen über `/v1/history`
+- Trainierbares statistisches Baseline-Modell mit persistierten Parametern
+- Numerische Vorhersagen mit Confidence sowie MAE-/RMSE-Evaluation
+
+## 0.1.0 - 2026-06-13
 - Projektinitiierung
 - Architektur, ADRs und Roadmap
+- Einheitliche produktive FastAPI-App für HA- und ML-Routen
+- Funktionierende ENV-Konfiguration und sauberer HA-503-Zustand
+- Persistente, validierte und gegen Path Traversal gehärtete Model Registry

 # SillyHome Next

-Modern, lokal-first und datenschutzfreundliches Smart-Home-Intelligenzsystem für Home Assistant.

+## Reifegrad
+
+Die aktuelle Entwicklungslinie ist vollständig aktor-zentriert: Nutzer wählen
+nur Home-Assistant-Aktuatoren aus. SillyHome Next findet Sensoren, Zustände und
+Kontext automatisch, wertet die vorhandene Historie aus und hält passende
+lokale Modelle autonom aktuell. Es gibt keinen Regel-, Trigger-, Sensor- oder
+YAML-Konfigurationsschritt.

 ## Motivation
 TheSillyHome zeigte die Idee: statt statischer Regeln das Zuhause aus Verhaltensmustern verstehen. Diese Architektur modernisiert den Ansatz in Richtung Explainable AI, hybride Intelligenzebenen und langlebige Wartbarkeit.

-In `.env` müssen für echte Home-Assistant-Daten diese Werte gesetzt werden:
-
-```bash
-SILLYHOME_HA_URL=http://homeassistant.local:8123
-SILLYHOME_HA_TOKEN=<long-lived-access-token>
-```

-Vor jedem Pull Request lokal laufen lassen:
+Niemals Administrator-Tokens oder Passwörter eintragen. `.env` gehört nicht ins
+Versionskontrollsystem.

+### Home-Assistant-Add-on
+
+Das Repository ist zugleich ein Home-Assistant-Add-on-Repository. In Home Assistant
+unter **Einstellungen → Add-ons → Add-on-Shop → Repositories** diese URL eintragen:
+
+`http://192.168.6.31:3000/pino/sillyhome-next`
+
+Danach **SillyHome Next** installieren und starten. Das Dashboard wird per Ingress
+geöffnet. Dort werden ausschließlich erlaubte Aktoren ausgewählt; Kontext- und
+Lernentscheidungen erfolgen automatisch.
+
+### Normaler Workflow
+1. Im Dashboard einen Aktor auswählen, zum Beispiel `light.abstellkammer`.
+2. SillyHome Next bewertet automatisch Messwerte, Anwesenheit, Bewegung,
+   Bereiche, Gerätebeziehungen und weitere HA-Kontexte.
+3. Das System verwendet selbstständig die beste verfügbare Zuordnung.
+   Niedrige Sicherheit bleibt als Diagnose sichtbar, verlangt aber keine
+   manuelle Konfiguration.
+4. Sobald genügend Historie vorhanden ist, trainiert und aktualisiert das
+   System das lokale Modell automatisch.
+5. Vorhersagen laufen zunächst ausschließlich im Shadow-Modus.
+6. Erst nach ausdrücklicher Freigabe pro Aktor werden hochkonfidente,
+   erlaubte Zustände geschaltet. Eindeutig im HA-Logbuch erkannte Automationen
+   und Scripts zählen dabei gleichwertig wie manuelle Bedienungen. Eigene
+   Schaltungen von SillyHome werden nicht zurückgelernt.
+7. Bei der Freigabe kann SillyHome passende HA-Automationen pausieren und die
+   Steuerung übernehmen. Beim Stoppen können diese Automationen gezielt wieder
+   fortgesetzt werden.
+
+Vor einem Update sollte in Home Assistant unter **Einstellungen → System → Backups**
+eine Teil-Sicherung des Add-ons erstellt werden. Zur Wiederherstellung das gewünschte
+Backup öffnen, **SillyHome Next** auswählen und wiederherstellen. Der erste produktive
+Teststand `v0.3.0` wurde als HA-Backup `7df0fca0` gesichert.
+
+### Tests
 ```bash
-pytest -q
+pytest
 ruff check .
-mypy app tests
+mypy app backend tests
 ```

+# Verhaltensmodell und Berechnung
+
+## Datenfluss
+
+1. Nutzer wählt einen Aktor.
+2. `ActuatorReconciliationService` ordnet Kontext-Entities zu.
+3. `BehaviorEngine.train()` liest Aktor- und Kontexthistorie.
+4. Aktor-Zustandswechsel werden als `BehaviorPattern` gespeichert.
+5. `BehaviorEngine.evaluate()` vergleicht aktuelle Zustände mit den Mustern.
+6. Shadow zeigt nur die Vorhersage. Active darf sie ausführen.
+
+## Herkunft und Gewicht
+
+- HA-Benutzer: `source=user`, Gewicht `1.0`
+- eindeutig erkannte HA-Automation oder Script: `source=automation`, Gewicht `1.0`
+- physisch oder unbekannt: `source=physical_or_unknown`, Gewicht `0.7`
+- eigene SillyHome-Ausführung: wird verworfen
+
+Manuelle und eindeutig automatisierte Handlungen zählen für die Freigabe.
+
+## Kausale Muster
+
+Wechselt ein Kontextsensor höchstens drei Sekunden vor der Aktorhandlung, wird
+der Wechsel gespeichert:
+
+```text
+binary_sensor.tuer: off -> on
+light.raum: off -> on
+```
+
+Eine kausale Vorhersage gilt nur, wenn derselbe Kontextzustand frisch ist. Das
+Standardfenster ist zweimal `SILLYHOME_PREDICTION_INTERVAL_SECONDS`.
+
+## Nicht-kausale Bewertung
+
+Für Muster ohne frischen Trigger:
+
+```text
+score = weight * (
+  0.45 * time_score
+  + 0.45 * context_score
+  + 0.10 * weekday_score
+)
+```
+
+Die Confidence ist der mittlere Score, begrenzt durch die Mindestunterstützung:
+
+```text
+confidence = mean(scores) * min(1, support / min_behavior_actions)
+```
+
+## Ausführungsbedingungen
+
+Eine Vorhersage wird nur ausgeführt, wenn alle Bedingungen erfüllt sind:
+
+- Betriebsart `active`
+- Confidence mindestens `SILLYHOME_PREDICTION_CONFIDENCE`
+- Zielzustand ist noch nicht erreicht
+- Domain und Zustand sind erlaubt
+- Cooldown erlaubt die Aktion
+
+Der Cooldown sperrt nur eine schnelle Wiederholung desselben Zielzustands.
+Eine Gegenaktion, beispielsweise `on` gefolgt von `off`, bleibt sofort erlaubt.
+
+## Freigabe
+
+`activation_ready=true`, wenn:
+
+- Verhaltensstatus `trained`
+- mindestens `SILLYHOME_MIN_BEHAVIOR_ACTIONS` eindeutig zugeordnete manuelle
+  oder automatisierte Handlungen vorhanden sind
+
+Die UI zeigt `activation_reason` immer an.

+# Übergabe zwischen SillyHome und HA-Automationen
+
+## Erkennung
+
+SillyHome liest aktive `automation.*`-Entities, lädt deren Konfiguration über
+die Home-Assistant-API und sucht darin nach der exakten Aktor-Entity-ID.
+Namensähnlichkeit allein reicht nicht.
+
+## Betriebsarten
+
+### Shadow
+
+- SillyHome lernt und prognostiziert.
+- SillyHome schaltet nicht.
+- HA-Automationen können normal weiterlaufen.
+
+### Active parallel
+
+- SillyHome darf schalten.
+- Passende HA-Automationen bleiben aktiv.
+- Diese Betriebsart kann doppelte Auslöser verursachen und ist nur für Tests.
+
+### Active mit Übernahme
+
+- SillyHome wird zuerst aktiviert.
+- Danach werden aktuell aktive, passend erkannte HA-Automationen pausiert.
+- Nur erfolgreich pausierte Automationen werden für eine spätere
+  Wiederherstellung gespeichert.
+- Scheitert die Pause, fällt SillyHome auf Shadow zurück und stellt bereits
+  pausierte Automationen wieder her.
+
+## Stoppen
+
+Zwei bewusste Optionen:
+
+- SillyHome stoppen und pausierte HA-Automationen fortsetzen.
+- SillyHome stoppen und HA-Automationen pausiert lassen.
+
+Einzelne passende Automationen können im Dashboard jederzeit pausiert oder
+fortgesetzt werden.
+
+In Home Assistant bedeutet:
+
+```text
+automation.turn_off = pausieren/deaktivieren
+automation.turn_on  = fortsetzen/aktivieren

+
+## Vorhersage korrekt, aber keine Ausführung
+
+1. Aktor-Details öffnen.
+2. `Betriebsart` prüfen.
+3. `Freigabestatus` prüfen.
+4. Text hinter der Vorhersage lesen. `execution_reason` nennt exakt:
+   - Shadow-Modus
+   - Confidence unter Schaltschwelle
+   - Zielzustand bereits erreicht
+   - Cooldown aktiv
+   - ausgeführt
+5. Live-Zustand des Aktors und Triggers in HA prüfen.
+6. Add-on-Logs prüfen.
+
+## Weder SillyHome noch HA-Automation schaltet
+
+1. SillyHome-Modus prüfen.
+2. Unter `Passende Home-Assistant-Automationen` den Zustand prüfen.
+3. Bei Shadow mindestens eine gewünschte HA-Automation fortsetzen.
+4. Bei Active mit Übernahme müssen die passenden HA-Automationen pausiert sein.
+
+## Freigabe fehlt

+5. Annotiertes Tag auf dem Merge-Commit erstellen.
+6. Gitea-Release aus demselben Tag erstellen.
+
+Beispiel:
+
+```bash
+git tag -a v0.7.0 -m 'SillyHome Next 0.7.0'
+git push origin v0.7.0

+ha apps update 58adbe1e_sillyhome_next
+ha apps info 58adbe1e_sillyhome_next
+ha apps logs 58adbe1e_sillyhome_next
+```
+
+Kein Home-Assistant-Neustart ist erforderlich.

+- `behavior.activation_ready`
+- `behavior.activation_reason`
+- `behavior.related_automations`
+- `behavior.paused_automation_entity_ids`
+- `behavior.prediction.execution_reason`
+
+Bei einer Übernahme testen:
+
+1. Passende HA-Automation ist vorher `on`.
+2. SillyHome übernimmt.
+3. SillyHome ist `active`.
+4. Passende HA-Automation ist `off`.
+5. Trigger erzeugt erwartete Aktoraktion.
+6. Gegenaktion wird trotz Cooldown ausgeführt.
+7. SillyHome stoppen und Automationen fortsetzen.
+8. SillyHome ist `shadow`, HA-Automation wieder `on`.
+
+## Rollback
+
+Bevorzugt das vor dem Update erstellte HA-Teil-Backup wiederherstellen.
+Alternativ vorherige Git-Version in `addon/config.yaml` veröffentlichen und das
+Add-on erneut aktualisieren.

+# Home-Assistant-Datenpipeline
+
+SillyHome Next trennt aktuelle Entity-Metadaten, Discovery und historische
+Messwerte. Dadurch gelangen nur klassifizierte, geeignete Daten in spätere
+Trainings- und Erklärungsprozesse.
+
+## Entity Discovery
+
+`GET /v1/discovery` klassifiziert Home-Assistant-Entities in:
+
+- `measurement`: numerische Messsensoren, für Training geeignet
+- `binary_context`: binäre Kontextsensoren wie Bewegung oder Anwesenheit
+- `context`: Personen-, Wetter- und Standortkontext
+- `actuator`: mögliche Automationsziele, nicht als Trainingssensor verwendet
+- `unsupported`: noch nicht klassifizierte Entity-Typen
+
+Zusätzlich reichert `HaReader` verfügbare Metadaten wie `friendly_name`,
+Bereich und Gerät aus Home Assistant an. Für die aktor-zentrierte Zuordnung
+nutzt SillyHome Next bevorzugt:
+
+- `area_id` und `area_name`
+- `device_id` und `device_name`
+- Friendly Names und Entity-ID-Tokens
+- Domain und `device_class`
+
+Optionale Query-Parameter:
+
+- `domain=sensor` kann mehrfach angegeben werden
+- `learnable=true|false` filtert nach Trainingsrelevanz
+
+## Historische Daten
+
+Historische Zustände werden über Home Assistants
+`/api/history/period/<start>`-Schnittstelle geladen. Abfragen verlangen:
+
+- mindestens eine Entity-ID, maximal 100
+- zeitzonenbehaftete Start- und Endzeit
+- ein Enddatum nach dem Startdatum
+- maximal 31 Tage pro Abfrage
+
+Die Normalisierung übernimmt nur endliche numerische Zustände. `unknown`,
+`unavailable`, nichtnumerische Werte, `NaN` und unendliche Werte werden nicht
+als Trainingsdaten verwendet. Ergebnisse werden je Entity chronologisch
+sortiert. Binäre Kontext-Entities werden bewusst nicht in numerische
+Trainingsreihen konvertiert.
+
+## Datenschutz und Betrieb
+
+Die Daten bleiben lokal. Home-Assistant-Tokens gehören ausschließlich in die
+Umgebungskonfiguration und dürfen nicht protokolliert oder versioniert werden.
+Die API sollte nur lokal oder hinter einem authentifizierenden Reverse Proxy
+erreichbar sein.

+## Fehlerfälle
+
+- `404 Not Found`: Modell nicht registriert.
+- `422 Unprocessable Content`: Sensor wird vom Modell nicht unterstützt oder Eingabe ist ungültig.
+- `503 Service Unavailable`: Registry ist nicht initialisiert.
+
+## Aktuator-zentrierte API
+
+### `GET /v1/actuators/discovery`
+
+Listet unterstützte Aktuatoren mit angereicherter HA-Metadatenbasis.
+
+### `POST /v1/actuators`
+
+Registriert einen Aktor. Das System ermittelt passende Messwerte und
+Kontext-Entities vollständig automatisch, trainiert bei ausreichender Historie
+ein Modell und liefert Zuordnung, Confidence, Evidenz und Lifecycle-Status zur
+Diagnose zurück.
+
+**Request**
+```json
+{
+  "actuator_entity_id": "light.abstellkammer",
+  "enabled": true
+}
+```
+
+### `POST /v1/actuators/reconciliation/run`
+
+Führt eine sichere globale Reconciliation aus. Die periodische Add-on-Schleife
+ruft denselben idempotenten Ablauf auf, startet aber keine Services in Home
+Assistant.
+
+### `POST /v1/actuators/{actuator_entity_id}/evaluate`
+
+Erstellt aus aktuellem Kontext eine neue Shadow- oder Aktiv-Vorhersage. Im
+Shadow-Modus wird niemals geschaltet.
+
+### `POST /v1/actuators/{actuator_entity_id}/activation`
+
+```json
+{
+  "active": true,
+  "pause_matching_automations": true,
+  "restore_paused_automations": false
+}
+```
+
+Aktiviert autonomes Schalten erst nach ausreichendem Training und nur für
+erlaubte Aktor-Domains. `pause_matching_automations` pausiert eindeutig
+zugeordnete HA-Automationen bei der Übernahme.
+
+Beim Stoppen:
+
+```json
+{
+  "active": false,
+  "pause_matching_automations": false,
+  "restore_paused_automations": true
+}
+```
+
+Damit wird der Aktor in den Shadow-Modus versetzt und zuvor von SillyHome
+pausierte Automationen werden fortgesetzt.
+
+### `POST /v1/actuators/{actuator_entity_id}/related-automations/refresh`
+
+Liest passende HA-Automationen anhand ihrer echten Konfiguration neu ein.
+
+### `POST /v1/actuators/{actuator_entity_id}/related-automations/control`
+
+```json
+{
+  "automation_entity_id": "automation.licht_abstellkammer",
+  "enabled": false
+}
+```
+
+Pausiert oder aktiviert eine eindeutig diesem Aktor zugeordnete Automation.
+
+## Betrieb
+
+Die produktive App lädt Artefakte aus `SILLYHOME_MODEL_STORE`. Aktor- und
+Reconciliation-Zustände liegen atomisch in
+`SILLYHOME_ACTUATOR_STORE`. Neue Artefakte werden über `/ml/retrain`,
+`RetrainingService` oder den aktor-zentrierten Lifecycle registriert. Die API
+sollte nur in einem vertrauenswürdigen Netz oder hinter einem
+authentifizierenden Reverse Proxy erreichbar sein.

+# Verhaltenslernen und Vorhersage
+
+Seit `v0.5.0` ist der produktive Lernpfad aktor-zentriert. Nutzer wählen nur
+einen Aktor; Sensoren, Kontext und Modelle werden automatisch verwaltet.
+
+## Datengrundlage
+
+Für jeden Aktor lädt SillyHome Next:
+
+- dessen Zustandswechsel aus der Home-Assistant-Historie
+- Logbook-Einträge zur Herkunft der Handlung
+- automatisch zugeordnete Mess- und Kontext-Entities
+- deren Zustand zum Zeitpunkt der Handlung
+
+Eindeutig einem Home-Assistant-Benutzer zugeordnete Handlungen und im Logbuch
+erkannte Automations- oder Script-Aktionen erhalten das höchste Gewicht.
+Physische oder nicht eindeutig zuordenbare Bedienungen dürfen das Shadow-Modell
+ergänzen, reichen allein aber nicht zur Aktivierung.
+
+## Modell
+
+Das lokale Modell speichert pro beobachteter Handlung:
+
+- Zielzustand
+- lokale Tageszeit
+- Wochentag
+- Kontextzustände
+- Herkunft und Gewicht
+
+Eine Vorhersage bewertet zeitliche Nähe, Wochentagsmuster und aktuellen
+Kontext. Mehrere passende historische Handlungen erhöhen die Confidence.
+
+## Betriebsstufen
+
+1. `collecting`: Noch nicht genügend Handlungen vorhanden.
+2. `shadow`: Modell ist trainiert; Vorhersagen werden angezeigt, aber nicht ausgeführt.
+3. `active`: Nutzer hat den Aktor ausdrücklich freigegeben.
+
+Die Aktivierung verlangt genügend eindeutig zugeordnete manuelle oder
+automatisierte Handlungen. Ausgeführt werden nur erlaubte Zustände reversibler Domains:
+`light`, `switch`, `fan`, `humidifier` und `cover`.
+
+## Schutzmechanismen
+
+- explizite Freigabe pro Aktor
+- konfigurierbare Mindestkonfidenz
+- Cooldown zwischen Schaltungen
+- keine Ausführung bei bereits erreichtem Zielzustand
+- keine Ausführung unbekannter Zustände oder riskanter Domains
+- eigene Schaltungen werden beim nächsten Training herausgefiltert
+- Automation-/Script-Aktionen zählen nur bei eindeutiger Herkunft im HA-Logbuch
