Hermes auto-triage classified incident metis/292 as transient_infra_failure (confidence 0.95); first failed gate: Build & push images.

Why a human is needed

The build completed its test reporting successfully with 309 passing tests and no structured failing tests. It failed later while exporting and pushing the arm64 image: the BuildKit gRPC client connection closed during the registry push. An earlier timeout against the local BuildKit endpoint indicates an unstable build daemon or connection path, but it was not the stopping error because the pipeline continued. The evidence does not indicate a defect in metis source code or tests; the immediate fix is to retry the unchanged build after the transient build/push connection has recovered.

Ariadne did not authorize automated remediation: evidence_signature_missing.

Facts

jenkins — Jenkins build metis #292 ended with result FAILURE, and Jenkins reported the first failed pipeline stage as "Build & push images". (metis/292; jenkins.first_failed_stage)
jenkins — The image export reached the registry push step, then failed while pushing registry.bstein.dev/bstein/metis:0.1.0-292-arm64 with "Canceled: grpc: the client connection is closing"; BuildKit then reported "failed to solve" with the same error. (console_failures line 2568)
jenkins — Earlier in the build, inspection of the local BuildKit container endpoint at localhost:2375 timed out with "context deadline exceeded". The pipeline explicitly continued afterward with "return 0". (console_failures line 1567)
jenkins — Jenkins published 309 passing test results in the post-action stage, and jenkins.failed_tests is empty. (jenkins.console_tail; jenkins.failed_tests)
jenkins — The console shows Sonar Go-parser errors for several files, but the scan continued through all 46 Go source files and no failed quality gate is recorded as the first failed stage. (console_failures line 1353; jenkins.first_failed_stage)

Evidence

The earliest failure region of the build console:

tty: true
    volumeMounts:
    - mountPath: "/home/jenkins/agent"
      name: "workspace-volume"
  - command:
    - "cat"
    image: "registry.bstein.dev/bstein/quality-tools:sonar8.0.1-trivy0.70.0-db20260422-arm64"
    name: "quality-tools"
    tty: true
    volumeMounts:
    - mountPath: "/home/jenkins/agent"
      name: "workspace-volume"
  - env:
    - name: "JENKINS_SECRET"
      value: "********"
    - name: "JENKINS_TUNNEL"
      value: "jenkins.jenkins.svc.cluster.local:50000"
    - name: "JENKINS_AGENT_NAME"
      value: "metis-292-dj4b3-pzlkt-dflg3"

Inferences

The enforced failure was the loss of the BuildKit client connection during image publication, not a repository test failure or a failed test assertion.
The earlier localhost:2375 timeout suggests the BuildKit daemon or its local connection was unstable before the final push failure. Because that earlier error was tolerated, the registry-push connection closure is the first failure that actually stopped the pipeline.
Re-running the same commit should be sufficient if the BuildKit/registry connection has recovered; no source change is supported by the supplied evidence.
