# BuildKit cache mount makes subsequent builds re-use the pip download
# cache so the second build only does install work — the slow ~60-90s
# fetch step from the first build becomes ~5s. Requires DOCKER_BUILDKIT=1
# (already set in test_docker.sh).

# has a floor) and requirements-dev.txt pins the one CI enforces, so a single
# install would have two exact pins for ruff and fail. The second one wins.

# Test image runs pytest and exits — there is no long-running service
# to probe. HEALTHCHECK NONE is the documented Docker opt-out and
# silences Trivy DS-0026 without adding meaningless probe logic.
HEALTHCHECK NONE

# Default command runs pytest (excluding docker integration tests).
# -v dropped: 5300+ "PASSED foo::bar" lines per worker eat noticeable
# stdout I/O time and clutter test_docker.sh output. --tb=short still
# gives full failure tracebacks when something breaks.
# -n auto adapts to the host's vCPU count instead of hard-coding 30 —
# on a 2-vCPU CI / VM runner, -n 30 spawns 30 Python processes fighting
# for 2 cores, which is mostly IPC + import-thrash overhead.
