# Forgejo Actions CI for Datarhei — Dragon Fork.
#
# Mirrors the upstream go-tests.yml shape (GitHub Actions syntax),
# but pinned to Go 1.24 to match go.mod and adds the M3 race-detector
# pass. The forgejo-runner picks this up automatically.
#
# Triggered on every push and pull request. Two jobs:
#   - lint-and-vet: cheap, fast feedback (~30s)
#   - test:        full test suite with -race, ~3 minutes including
#                  the integration tests in app/webrtc that bind UDP
#                  sockets and run a real Pion handshake.

  # --- WebRTC subsystem-only smoke ---------------------------------
  # The 5-viewer fanout test catches the largest class of regressions
  # for the egress path. Promoted to its own job so a failure on the
  # WebRTC side reads cleanly in the actions log instead of being
  # buried among ~80 packages of unrelated Core tests.
