# Build-time profile tuning. `target/debug/deps` had grown to 73G across
# 2.45M `.rcgu.o` files: macOS defaults dev builds to
# `split-debuginfo = "unpacked"`, which leaves per-codegen-unit object
# files in `deps/` for the debug map, and cargo never collects them. With
# one integration-test binary per `tests/*.rs` file (150+), each carrying
# full debuginfo, that accumulates fast and every fingerprint pass then pays
# lookups in a multi-million-entry directory.
#
# `debug = 1` keeps line tables — backtraces still carry file/line — but
# drops local-variable info, so an lldb session can't inspect locals.
# Raise back to 2 if you need to step through roundhouse itself.
