# Unit and gate tests. The M0 scaffold ships a single smoke test that proves
# the build produces a runnable artefact and the spike runner emits the
# contract JSON the CI pipeline parses. As the layers land (L1–L6), each gets
# its own test executable under here, all registered with CTest.

# We do not pull GoogleTest yet — the first tests are plain freestanding mains
# returning non-zero on failure, which keeps the M0 scaffold dependency-free
# and lets CI on all three platforms run ctest without a vcpkg build of gtest.
# A later milestone swaps in GTest once there is real C++ logic to assert on.
