+Subject: [PATCH] TEMP: AzDO truncation test for microsoft/go#2046
+
+Adds a deliberately-failing fmt test that emits ~100,000 characters of failure output between AZDO-TRUNCATION-TEST-BEGIN/END markers, to verify that the AzDO test viewer now surfaces an output-truncation indicator. Revert this commit (and the corresponding patch file) once verification is complete.
