  "message": "Disable Buildkite commit verification for google-bazel-presubmit (#2890)\n\nNew images pick up **Buildkite agent v4** (the agent is installed\nunpinned from the apt `stable` channel / GitHub `releases/latest`).\nAgent v4 defaults `git-commit-verification` to `strict`, which breaks\nevery `google-bazel-presubmit` job that lands on a new VM, e.g.\nhttps://buildkite.com/bazel/google-bazel-presubmit/builds/110111:\n\n```\n$ git merge-base --is-ancestor 5f1bfb3f... 864445577c...\n🚨 Error: commit verification failed: commit \"5f1bfb3f...\" is not on branch \"master\"\n```\n\nThose builds are created with `branch\u003dmaster` but check out an\nunsubmitted Gerrit change, which is never an ancestor of master. Agents\nstill on 3.137.0 pass, so failures are intermittent while old and new\nVMs are mixed.\n\n### Change\nSet `BUILDKITE_GIT_COMMIT_VERIFICATION\u003doff` for `google-bazel-presubmit`\nonly, in the agent `environment` hook on Linux\n(`startup-docker-pdssd.sh`) and Windows (`startup-windows-pdssd.ps1`).",
