# Start MongoDB *after* the heavy build, immediately before the tests that
# need it. Unlike postgres/mysql (declared as health-gated `services`),
# MongoDB is started by an action step with no readiness gate, and the
# test harness connects once with no retry. Starting it before the ~10m
# build left a long window where the container could be resource-starved
# and become unreachable, producing flaky "Connection refused" failures
# in the persistent-mongoDB suite.
