  "message": "[pinpoint] handle all values equal edge case in ComparePairwise\n\nWhen every element of valuesA is identical and every element of valuesB\nis identical, the wilcoxon signed rank test is unable to estimate a\nconfidence interval. However, the underlying data is still useful. We\nnudge one of the values by an insignificant amount to unblock the\nanalysis and return a valid confidence interval.\n\nThis edge case is not supported in catapult and will return an error,\nblocking bisection.\n\nBug: b/332612913\nChange-Id: I90e1397cd2e5dd04a0a22420caa311d13e7945af\nReviewed-on: https://skia-review.googlesource.com/c/buildbot/+/862501\nReviewed-by: Kaylee Lubick \u003ckjlubick@google.com\u003e\nCommit-Queue: Leina Sun \u003csunxiaodi@google.com\u003e\n",
