 ## 🟠 Sprint B — Kurzfristig (nächste Woche)
 
-- [ ] **B-1** | CI/CD Pipeline für Compose Desktop Tests (headless)
-  - [ ] GitHub Actions / Gitea Actions Workflow anlegen
-  - [ ] Headless-Umgebung für Compose Desktop Tests konfigurieren (Xvfb oder virtueller Framebuffer)
-  - [ ] Gradle-Task für Desktop-Tests in Pipeline integrieren
-  - [ ] Build-Artefakte (JAR / native Binaries) als Pipeline-Ausgabe speichern
-  - [ ] Fehlgeschlagene Tests als Build-Blocker konfigurieren
+- [x] **B-1** | CI/CD Pipeline für Compose Desktop Tests (headless)
+  - [x] Gitea Actions Workflow angelegt: `.gitea/workflows/desktop-tests.yml`
+  - [x] Headless-Umgebung: `xvfb-run` (1920x1080x24) für Compose Desktop Tests
+  - [x] Gradle-Task integriert: `:frontend:shells:meldestelle-desktop:jvmTest`
+  - [x] Build-Artefakte gespeichert: `frontend/shells/meldestelle-desktop/build/**` (JARs und Compose-Distributables)
+  - [x] Fehlgeschlagene Tests brechen Build ab (Default-Verhalten von Gradle `jvmTest`)
 
-- [ ] **B-2** | Gradle-Build-Optimierungen
-  - [ ] Build-Cache aktivieren und prüfen
-  - [ ] Parallele Modul-Builds konfigurieren
-  - [ ] Gradle-Wrapper-Version auf aktuellen Stand bringen
+  Hinweise:
+  - CI nutzt JDK 21 (Temurin), Gradle-Cache (`actions/cache`).
+  - Artefakte: Upload via `actions/upload-artifact`. Pfade siehe Workflow.
+  - Siehe: `docs/01_Architecture/Gitea/Enable_Gitea_Actions_Cache_to_Accelerate_CI_CD.md` für Runner-Cache.
+
+- [x] **B-2** | Gradle-Build-Optimierungen
+  - [x] Build-Cache aktiv: `org.gradle.caching=true` (in `gradle.properties`)
+  - [x] Parallele Builds aktiv: `org.gradle.parallel=true` (in `gradle.properties`)
+  - [x] Headless-Flag gesetzt: `-Djava.awt.headless=true` (in `org.gradle.jvmargs`)
+  - [x] Wrapper aktualisiert: Gradle `9.4.0` (kompatibel mit aktuellem Setup)
