Failure patternThe canonical description of a recurring CI failure, extracted and normalized from raw logs.Failed atThe stage of the job run where this failure occurred: 'provision' (environment setup, DEV only), 'e2e' (test suite execution), or 'other' (CI infrastructure issues that did not produce a failure pattern).Number of distinct job runs where this failure pattern was detected.Percentage of all job runs in this environment affected by this failure pattern during the selected window.Classification of this failure pattern: Regression (likely caused by a specific PR), Flake (intermittent failure spread across days), Noise (low-quality or generic pattern), or Indeterminate.TrendShows daily activity for this failure pattern in a trailing window anchored to the selected end date. The sparkline covers at least 7 days and at most 14 days, depending on the current window size.Also inOther environments where the same failure pattern was also detected during the selected window.
