# Fixture-backed integration leg (#757 item b). UNVERIFIED on a hosted runner until its first run.
#
# Separate from v2-ci.yml on purpose: the 60-minute whole-solution unit-tests job is untouched, so
# it gets no slower or flakier. This workflow builds ONLY the five fixture-backed *.IntegrationTests
# projects and runs them against THROWAWAY containers that the job itself creates and removes
# (scripts/ci/integration-fixtures.sh): SQL Server 2022, PostgreSQL 17 (seeded), QuestDB and the public
# opc-plc image. Nothing here touches the shared 10.100.0.35 host, so CI does not depend on that box.
#
# Explicit `docker run` steps rather than a `services:` block: whether the Gitea act_runner honours
# `services:` (and makes service ports reachable from the job) is not documented in infra/README.md §10,
# and the Sql/Postgres fixtures need a post-start seed step anyway. The script needs only a reachable
# docker daemon on the runner.
#
# Gate: MIN_EXECUTED turns a fixture outage (every test Assert.Skip-ing) into a RED job instead of a
# silent green, which is the whole point of this leg. Not covered here (no public/pullable image or
# needs credentials/TLS): Modbus/S7/AB/FOCAS/TwinCAT sims, Mqtt, MTConnect, Oracle, Host real-infra mode.

# Triggers start CONSERVATIVE (manual + nightly) because the shared runner is already heavily loaded
# (#718: load avg ~35-51 on 22 cores during unit-tests) and this leg is unverified on it. Once the first
# hosted runs are green and the runner has headroom, widen to push/PR on master (paths below).
#   push: { branches: [master] }
#   pull_request: { branches: [master], paths: ["src/Drivers/**", "src/Core/**", "tests/Drivers/**", "scripts/ci/**", ".github/workflows/v2-integration.yml"] }
