+# Feature B (+C) — Security-Scan (HART blockierend) + KI-Klartext-Erklärung.
+# Pilot: läuft auf Push zum Branch ci-ai/pilot (Validierung) und auf PRs.
+# Schlankes alpine-Image + Memory-Cap (Pi-Runner). ⚠ ARM64-Binaries!
+# Gitleaks (Secrets) + Trivy config (IaC/Misconfig) — ohne schweren Vuln-DB-Scan.
+# Funde -> Check schlägt hart fehl; danach erklärt die KI sie (skippt ohne Key).
