+"""DEPRECATED: NightVision emits GitLab DAST reports natively now.
 
-import json
-from datetime import datetime
+This SARIF-to-GitLab converter has been retired. It mislabeled DAST findings as
+SAST and used unstable rule ids as the vulnerability id, so GitLab could not
+deduplicate findings across pipelines. Use the NightVision CLI's built-in command
+instead, which produces a correctly categorized DAST report with a stable
+per-finding fingerprint (so GitLab tracks findings across pipelines), NightVision
+branding, and real scan times:
 
+    nightvision export gitlab -s <scan-id> [--swagger-file <spec>] -o gl-dast-report.json
