# Requires nutest as a sibling at ../nutest. In the monorepo that sibling is a
# symlink to the one checkout outside it, which other modules also use.
#
# Why one thread by default: nutest's own default runs every suite in parallel
# and every test inside it in parallel too. Under Apple `container` that spawn
# density wedges the terminal of the whole VM — the guest keeps working, but
# nothing it prints reaches the screen until the machine is restarted. Measured
# on nu-multiproof, whose suite has the same shape: thirty single-threaded runs
# never wedged, the parallel form went down on the fourth or fifth. The fault is
# in the runtime rather than here, so this default should go once it is fixed
# upstream. Pass --threads 0 for the old behaviour (0 means one per core).
# The investigation is not on any live branch — it lives in an archived tag of
# the cozy repo: git show archive/debug-freeze:todo/20260830-debug-freeze.md
