 # Changelog
 
-## Unreleased
+## 0.4.0 - 2026-06-13
-- Deterministische, nutzerverständliche Erklärungen für jede Modellvorhersage
+- Aktuator-zentrierte Einrichtung: Nutzer wählen nur noch Aktuatoren, Sensoren werden deterministisch gefunden und bewertet
-- Persistenter Automation-Freigabeprozess mit sicherem YAML-Export
+- 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

 ## 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.

 SillyHome Next trainiert ein lokales statistisches Baseline-Modell pro Sensor
 und Merkmal. Es benötigt keine Cloud und keine externe ML-Laufzeit.
 
+Seit `v0.4.0` ist der bevorzugte Weg aktor-zentriert: ein bestätigter Aktuator
+wird mit einem numerischen Primärsensor verknüpft, die Historie dieses Sensors
+wird automatisch geladen und in ein deterministisches Artefakt überführt.
+
 ## 1. Daten sammeln
 
 Alle Trainingsvektoren werden über `FeatureStore.add(...)` oder `add_batch(...)` eingepflegt. Jeder Vektor enthält eine Sensor-ID sowie ein Dictionary mit Merkmalen.
 
+Im Normalbetrieb erzeugt die Reconciliation diese Vektoren selbst aus realer
+Home-Assistant-History. Das Trainingsmerkmal heißt dabei immer `value`.
+Binäre Kontextsensoren bleiben Kontext und werden nicht als numerische Samples
+missverstanden.

+
+Der `ActuatorReconciliationService` verwaltet pro konfiguriertem Aktuator:

+- persistente manuelle Overrides
+- den Modellstatus (`trained`, `pending_history`, `review_required`, `archived`, ...)
+- ein Audit-Protokoll mit Gründen für Training, Retraining oder Archivierung
+
+Retraining erfolgt nur, wenn:

+- genügend nutzbare numerische Historie vorliegt
+- die aktuelle Zuordnung eindeutig oder manuell bestätigt ist
+- die Historie sich materiell verändert hat oder das Modell als stale gilt
+
 ## Hinweise
 - Für reproduzierbare Sensor-Reihenfolgen wird in `TrainingPipeline.run(...)` eine sortierte Sensor-Liste verwendet.
 - Fehlende Trainingsdaten lösen `ValueError` aus; nicht registrierte Artefakte lösen `KeyError` aus.
