# Golden tests: every case of cases.txt must produce the recorded output.
# MYOS_ENGINE=legacy (default) runs the make engine, MYOS_ENGINE=cli runs bin/myos.
# For the cli engine, spec/golden/expected.cli/<case>.txt overrides the legacy
# expectation when a delta is intentional (documented in DELTAS.md).
