# Continuous integration for mxaccessgw (Gitea Actions; origin is Gitea at gitea.dohertylan.com).
#
# Scope note: the x86 Worker (src/ZB.MOM.WW.MxGateway.Worker) and Worker.Tests target
# .NET Framework 4.8 / x86 and need MXAccess COM installed, so they build ONLY on a Windows host.
# They are out of scope for this Linux `portable` job — the `windows-x86` job below builds and
# tests them on windev (10.100.0.48) over SSH (see scripts/ci/run-windev-ci.sh), and the nightly
# `nightly-windev` job additionally runs the live-MXAccess smoke, which is scheduled-only so it
# never gates a push.
