 Status: lebendes Projektdokument  
 
+Defender-Profil 1.2.0 2026-09-11 (Phase 6/13A): Das Profil verarbeitet die synthetischen `Mock-Defender`-Dateien `cves.csv` und `device_inventory.csv` ueber den generischen CSV-Adapter und verbindet sie ausschliesslich ueber `Device ID`. Site und Sensor stammen nur aus vorhandenen Feldern; CVSS, Component und Mock-Workflowstatus bleiben Evidenz und werden nicht als nativer Gesamtscore oder Pass/Fail interpretiert. Source Extractor 1.1.0 und Processing-Manifest 1.2.0 sind append-only registriert; Profil 1.1.0 bleibt lesekompatibel, wird aber als aktualisierbar markiert.
+
 Defender-for-IoT-Drilldowns 2026-09-11 (Phase 7): CVE-, Device- und Site-Details erscheinen inline unter der ausgewaehlten Zeile mit stabilen, zugaenglichen Auf-/Zuklappzielen und gemeinsamer gelber Auswahlmarkierung. CVE-Evidenz zeigt betroffene Geraete flach; redundante Beschreibungs-, Observation- und Sensorangaben bleiben in den jeweils passenden Detailkontexten statt in der Uebersicht. Die Detailflaeche verwendet die gemeinsame Tile-Oberflaeche. Der NVD-Adapter uebernimmt `baseSeverity` aus den CVSS-Metriken. Reine Darstellungs-/Adapterkorrektur ohne Persistenz- oder Reimportaenderung.
 
 Defender-for-IoT-Client-Info-Stil 2026-09-11 (Phase 7): Microsoft Defender for IoT bleibt eine eigenstaendige Client-Info-Registerkarte mit CVE-, Device- und Site-Ansichten. Sie verwendet denselben themenabhaengigen Client-Info-Canvas, dieselbe Kopfzeile, denselben Panel-Inset sowie die flache Kachel-, Flaechen-, Typografie-, Auswahl- und Responsive-Grammatik wie Overview. Scannerprojektion, Finding-Semantik, Scoreberechnung, Import- und Persistenzvertraege bleiben unveraendert; kein Reimport erforderlich.

+Microsoft Defender for IoT verwendet weiterhin den generischen Excel-/CSV-Formatadapter. Ein kleiner Source Extractor verarbeitet sowohl das bisherige Summary-/Detailtabellenpaar als auch die synthetischen `Mock-Defender`-CSV-Dateien `cves.csv` und `device_inventory.csv`. Die Mock-CVE-Datei wiederholt Site und Sensor als ausdruecklich simulierte Fixture-Felder, damit ein Einzelimport die CVE-Ansicht vollstaendig speist; bei einem Mehrdateiimport verbindet das Domain-Modell CVE- und Inventarzeilen weiterhin ausschliesslich ueber die explizite `Device ID`. Fehlende Kontext- oder Beschreibungswerte werden nicht erfunden. Der Extractor erzeugt genau ein Finding-Vorkommen je Device und CVE, aggregiert diese je CVE und bewahrt CVSS Score, Component, Status sowie wiederholte Sensorzeilen als Evidenz. Summary-Werte ohne Detail-CVE bleiben separate Aggregate und werden nicht in Findings umgewandelt. Die fachlichen CVE-, Device- und Site-Projektionen liegen ausserhalb der React-Komponente in einem deterministischen Domain-Modell.
