# CI for the v2 branch — runs on every push + PR to the v2-akka-fuse / master
# branches. Layered into two jobs:
#   build           dotnet restore + build (fast feedback on compile errors)
#   unit-tests      the WHOLE solution minus the env-gated tiers (self-maintaining)
#
# Skips E2E (Category=E2E) and LiveIntegration (needs a real gateway/PLC/VPN) — both
# are env-gated tiers with no hosted-runner fixtures. (The skip-gated *.IntegrationTests
# still run in the unit-tests leg and Assert.Skip when their fixtures are unreachable.)
#
# Compatible with both GitHub Actions and Gitea Actions (act_runner). The .NET 10
# SDK is pinned via global.json at the repo root; if no global.json exists, the
# setup-dotnet step falls back to dotnet-version below.

  # NOTE (07/P-5): the former `integration` matrix job (Host.IntegrationTests +
  # OpcUaServer.IntegrationTests) was removed as fully redundant — the unit-tests leg
  # above already runs BOTH projects under the identical filter, fixtureless, and gates
  # them at MIN_EXECUTED=1. Its only unique output was a report-only skip tally the unit
  # leg's trx already contains. FOLLOW-UP (S-2 option #2): if a fixture-backed integration
  # leg is wanted, add it as a NEW job that starts the one public-image fixture as a
  # `services:` block (mcr.microsoft.com/iotedge/opc-plc; the modbus/S7/AB/FOCAS sims are
  # locally-built `otopcua-*` images not pullable here), sets OPCUA_SIM_ENDPOINT, and gates
  # at MIN_EXECUTED=1 so a fixture outage turns the job red — covering something the unit
  # leg cannot, rather than re-running the same fixtureless tests.
