Classification: Infrastructure flake (external dependency download failure get.helm.sh). Not a test flake.

• Not a matrix cancellation artifact: run_attempt=1; only lint failed; other jobs passed; required aggregator failed because lint failed.
• Subsequent runs on main are green, indicating a transient outage.

Duplicate check:

• Searched coder/internal for helm/azure/setup-helm/get.helm.sh download failures. No existing matching issue found.

Proposed next steps:

• Increase retries/backoff for azure/setup-helm or add a fallback mirror for Helm downloads.
• Consider pinning a cached Helm binary in CI or mirroring get.helm.sh to reduce external dependency flakiness.

If ownership is Dev Infra/Build CI, please triage accordingly. Leaving unassigned since this is an infra workflow concern rather than a test-owned area.
