-# Security scanning on every push/PR + weekly re-run.
+name: security
+# CI-10 — gitleaks, Semgrep, OSV-Scanner, Trivy. Körs på PR, på push mot main
+# och nattligt. Scannrarna körs som containrar för att inte kräva att runnern
+# har verktygen installerade.
 #
-# This job runs the same Trivy invocation as ci.yml's `security` job and
-# previously carried the same defect: `--exit-code 0` meant it could report
-# success while holding a CRITICAL finding (measured 2026-09-08 with a
-# planted AWS secret key -- detected, still exit 0). Its context
-# "Security Scan (SIAX Cloud) / security" is NOT in branch protection's
-# required list, so this one never gated a merge either way; it is fixed
-# here so a green tick on this workflow means what a reader assumes it
-# means. See ci.yml's `security` job for the measurement and for the
-# services/scrapers unpinned-requirements coverage gap.
+# FÄLLA (verifierad i SIAX-utredningen 2026-11-11): tre fel gjorde att
+# security-gaten aldrig kunde bli grön och blockerade varje PR.
+#   1. `-v "$PWD:/repo"` monterar en sökväg som är tom inuti runner-containern,
+#      så gitleaks rapporterade "no leaks found" på ett tomt träd och
+#      OSV-Scanner avslutade med 128 "No package sources found".
+#   2. `--volumes-from "$HOSTNAME"` fungerar för gitleaks/trivy/osv men
+#      Semgreps docker-wrapper kräver koden på /src och ger annars exit 2
+#      ("Detected Docker environment without a code volume").
+#   3. actions/@v4 är en muterbar tag som Semgrep-regeln
+#      github-actions-mutable-action-tag fäller; åtgärden pinnar samma SHA som
+#      repots övriga jobb använder.
+# Åtgärden: arbetsträdet kopieras en gång till en namngiven volym som alla
+# scannrar monterar, och OSV hoppar över repos utan låsfil (då finns inget att
+# scanna — det är inte samma sak som en grön gate på riktigt).
 #
-# NOTE: findings on services/scrapers/* (FlareSolverr/Tor/curl_cffi) are
-# expected and out of scope for CI gating -- kept per the account owner's
-# dated, attributed decision (Simon Axelsson, 2026-08-11, interactive
-# prompt; no rationale beyond "keep it" given or invented). See SECURITY.md
-# and docs/compliance/GOLDEN-STANDARD-REPORT.md control C6 for full context.
