# Bootstrap (AZ-263) ships placeholders so this directory parses cleanly even
# when no native source has been written yet.

# BUILD_FAISS_INDEX no longer adds a CMake target — AZ-306 chose the
# `faiss-cpu` PyPI wheel over a custom pybind11 wrapper. The flag is
# preserved in cmake/build_options.cmake because it's still consumed
# at runtime by `gps_denied_onboard.runtime_root.build_flags` to gate
# the FaissDescriptorIndex import in the storage factory.
