# 2026-10-15: added after combining DEBUG=1 and TEST=1 for the first
# time (ever, as far as anyone could tell) turned up three real,
# previously-undiscovered bugs in a single run -- none in production
# code, all in self-test-only harnesses whose assert-guarded invariants
# had apparently never been checked with asserts actually compiled in
# (plain TEST=1 has no DEBUG, so ASSERT is a no-op; DEBUG=1 alone never
# links the self-test .o files at all). Unoptimized, so this step is
# the slow one -- budget a couple of minutes, not seconds.
