# NO DEVICE. test_queue.c runs against simulated cores behind the ft_tt_noc_access vtable
# and a software MODEL of the resident kernel, so it runs on the Mac. What it cannot cover
# is whether kernels/resident_queue.c compiles to that model — that is
# Makefile.phase5's test_phase5_resident on silicon, and nothing here substitutes for it.
#
# `red` rebuilds from scratch every time: Apple ships GNU make 3.81, whose one-second
# mtime granularity silently skips a rebuild of a source edited in the same second as its
# object, so a mutation loop that relies on incremental make can be testing the PREVIOUS
# binary (coding-best-practices.md §9).
