The clearest signal today is around container lifecycle correctness in the kubelet, with three separate fixes closing gaps in how containers start, stop, and get probed. PR 141487 stops probe state from leaking into a replaced container, PR 141484 makes sure a pre-stop sleep hook actually stops when its container…
Second theme: the scheduler's push toward staging continues. mengcar landed PR 141463, replacing a dependency on core validation with a local constant, and opened PR 141499 to do the same for a test image utility. Both are framed explicitly as removing k-slash-k imports so pkg slash scheduler can eventually move to…
Third theme: flakiness and observability cleanup. troychiu refactored kubelet command runner and CRI metrics instrumentation in PR 141480. Several PRs targeted test reliability directly — Rajalakshmi-Girish's fix for a metrics race in PR 141336, jackfrancis working to de-flake a time travel health check in PR…
