Problem

The ARM runner needs to be updated; ARM jobs were hanging.

Fix

   build-multi-arm64:
     runs-on:
-      - buildjet-4vcpu-ubuntu-2204-arm
+      - ubuntu-24.04-arm

Verification

  • The CI run on this PR should show build-multi-arm64 picking up a hosted ARM runner and building.

🤖 Generated with Claude Code

…dJet

The build-multi-arm64 job targeted `buildjet-4vcpu-ubuntu-2204-arm`, an
external BuildJet hosted runner. BuildJet is no longer available to the org,
so the label matched no runner and the job queued indefinitely (the recent
build failed after waiting ~24h for an ARM runner), blocking the dependent
`merge` job.

Unlike the platform repo, plateau has no self-hosted ARM runners available
(jobs targeting 8x32g-arm / 4x16g-arm stayed queued indefinitely with no
runner), which is presumably why ARM was on BuildJet to begin with. Since
plateau is a public repo, GitHub-hosted ARM runners (ubuntu-24.04-arm) are
free and require no self-hosted infrastructure -- and this matches the
amd64 job, which already runs on GitHub-hosted ubuntu-latest.
