Notable Observations
-
Failure volume is moderate — 253 is between the low of April 2026 (180) and the spike of March 2026 (433), suggesting a relatively normal month of development churn.
-
Top issue accounts for 105 of 253 failures (41%) — linked to message-id
CAPpHfdvht=_VcpDybYvwon96Enh=-S-9wGLGPzbu+6_5QmwmwQ@mail.gmail.com, marked Fixed. This continues the pattern where a single broken commit dominates monthly noise. -
5 of top 6 issues are marked Fixed — indicating quick turnaround on the dominant failures. The one exception (
CA+hUKGL0bikWSC2XW-zUgFWNVEpD_gEWXndi2PE5tWqmApkpZQ@mail.gmail.com, 10 failures) has no annotation, suggesting it may still be open or under investigation. -
One issue references a commit directly (
6f0bff33d, 23 failures, Fixed) rather than a mailing list thread — this is a minor format variation suggesting the fix commit was the most relevant identifier. -
REL_18_STABLE at 22 failures — continues its growth trajectory as more animals test this branch, consistent with prior trend observations.
-
Triage backlog (44 unsorted) is in the mid-range, suggesting Lakhin is keeping pace but not fully caught up.
