Summary

  • pull Meta moxygen source-head interop client from GHCR
  • exercise all six relay cases against current moq-dev/moq over WebTransport and raw QUIC
  • keep the known announce-subscribe mismatch non-blocking in CI while preserving a nonzero local exit
  • document the lane and guard both moving source-head inputs in freshness checks

Validation

  • just check
  • workflow YAML parse
  • moxygen image --list
  • published relay: 5/6 over WebTransport and raw QUIC
  • current moq-dev HEAD: 5/6 over WebTransport; announce-subscribe closes the subscriber session

actionlint was unavailable locally.

Review Change Stack

Walkthrough

Adds a moxygen interoperability smoke test that builds or uses a moq-dev relay, starts it with temporary TLS credentials, and runs the moxygen client over WebTransport and QUIC. Adds local and CI entry points, freshness checks for the client image and relay installation, and README documentation. The CI job allows failures because the current relay fails the announce-subscribe scenario.

Merge Risk: 🟡 Moderate · up to e6ac8

The new interoperability lane remains non-blocking for the known announce-subscribe mismatch, but it can also conceal unrelated lane failures and regressions. Restrict non-blocking behavior to that known case before merging.

Keep setup and unrelated test failures blocking.

continue-on-error: true applies to the entire moxygen job. A checkout failure or any nonzero result from moxygen.sh, including relay setup, image pull, or either transport run, can therefore produce a successful job. Allow only the known announce-subscribe mismatch through an explicit CI-only exit status in moxygen.sh, then remove the job-level flag.

Keep unrelated moxygen.sh failures blocking.

continue-on-error: true applies to the entire interoperability step. It can hide relay setup failures, image-pull failures, and unrelated transport failures. Make moxygen.sh return zero in CI only when announce-subscribe is the sole known failure, then remove this step-level flag.
