+# Lives in microsoft/RAMPART so the Azure Pipelines GitHub App can
+# trigger on PRs to main. All real logic lives in RAMPART-Internal so
+# it can be edited without a public-repo PR; this file is a thin
+# extends-only shim.
+#
+# Fork-PR semantics (configured in the ADO pipeline UI, not here):
+#   - In-repo branch PR  → auto-runs (secrets available).
+#   - Maintainer fork PR → auto-runs (secrets available).
+#   - External fork PR   → waits for `/azp run` comment from a
+#                          write-access user, per
+#                          "Require a team member's comment" setting.
+#
+# Blast radius if a malicious fork PR slips past `/azp run`: the
+# integration MI holds only `Cognitive Services OpenAI User` on a
+# single AOAI account. No KV access, no other Azure resources.
