+# IntelligenceX Reviewer Rollout Proof
+
+This file is a harmless PSTeams change used to verify that the newly installed
+IntelligenceX reviewer workflow runs on normal pull requests after the workflow
+has landed on `main`.
+
+Expected signal:
+- The `IntelligenceX Review` workflow starts on the proof pull request.
+- The reviewer posts a sticky summary comment.
+- The run uses the repository-local `.intelligencex/reviewer.json` configuration.
