KBE authoring guidance (ci-failure-scan)
Error Detailsis for readers. Paste the full exception, stack trace, or build error excerpt so the failure is understandable without opening the raw log.- Build Analysis parses only the single JSON block under
Error Message. ErrorMessageis a case-sensitive ordinalString.Containssubstring copied verbatim from the failing log.- Set
BuildRetrytotrueonly for a clear infrastructure retry case.ExcludeConsoleLogdisables Helix console-log scanning.
One case of the theory failed during the TLS handshake on linux-x64 Debug with the Mono interpreter (Helix job e2f92b64-6f5b-4da3-83db-315490f3d09f, work item System.Net.Security.Tests): 5081 total, 1 failed. The certificate validation callback rejected the remote certificate. The PR build that hit this doesn't touch System.Net.Security or Mono, and the test didn't fail in the main runtime build 1619318.
Existing KBE #133418 covers other SslStream failures (TLS resume and IncorrectServerName) that appeared in the same build on windows-x86. It doesn't match this failure because its ErrorMessage doesn't appear in this work item's log.
