Hermes auto-triage classified incident metis/369 as transient_infra_failure (confidence 0.98); first failed gate: Build & push images — resolve Dockerfile frontend docker.io/docker/dockerfile:1.7.

Why a human is needed

BuildKit could not reach Docker Hub's authentication endpoint over IPv6 while fetching the Dockerfile frontend, so image building stopped before application build instructions ran. Retry the same commit; no source or test change is indicated. If the same error recurs, correct the builder's outbound connectivity through repository-managed infrastructure configuration, ensuring working IPv6 egress or a usable IPv4 connection to Docker Hub.

Ariadne did not authorize automated remediation: evidence_signature_missing.

Facts

jenkins — Jenkins reports FAILURE and identifies Build & push images as the first failed stage. (jenkins.result; jenkins.first_failed_stage)
jenkins — BuildKit failed while resolving docker.io/docker/dockerfile:1.7, requested by Dockerfile line 1. Fetching an anonymous token from auth.docker.io failed with an IPv6 connection error: dial tcp [2a06:98c1:3104::6812:2bb2]:443: connect: network is unreachable. (jenkins.console_failures[4], line_number 1636)
jenkins — No failing tests are listed in failed_tests. The console records 96.4% Go coverage and gate_rc=0, and the post-build test publication reports 309 passed. (jenkins.failed_tests; jenkins.console_failures[0], line_number 1342; jenkins.console_tail)
jenkins — The agent briefly went offline during SonarQube evidence collection, then came back online. SonarQube subsequently reported Go parser errors, but execution continued into image preparation and Build & push images. (jenkins.console_failures[0], line_number 1342; jenkins.console_failures[1], line_number 1395; jenkins.console_failures[3], line_number 1608)
jenkins — Earlier image preparation reported an arm64 binfmt registration error and a Docker API context deadline exceeded. The latter excerpt shows return 0 before the pipeline entered Build & push images. (jenkins.console_failures[2], line_number 1560; jenkins.console_failures[3], line_number 1608)
opensearch — OpenSearch evidence collection returned connection refused and supplied no log records. (log_evidence.error; log_evidence.records)

Inferences

The first enforced failure was Dockerfile frontend retrieval during image building, not a test assertion, SonarQube parser error, or agent provisioning failure.
The failing request concerns external registry connectivity and occurred before BuildKit could execute the application's Dockerfile instructions. The evidence does not indicate a defect in Metis source or tests.
The IPv6 connection was unreachable during this build; the bundle does not establish whether that networking fault was temporary or persistent. The separate OpenSearch collection error does not establish a shared cause.
