	# `native/lgj-abi/.cargo/config.toml` pins `-Ctarget-cpu=x86-64-v4`
	# (AVX-512) because the production artifact is built for one known host.
	# GitHub-hosted runners do not guarantee AVX-512, so a v4 build would emit
	# instructions the runner cannot execute and die with SIGILL — the exact
	# fault that config's own comment describes. It names the remedy for a
	# machine without AVX-512: override the baseline at build time with v3.
	# AVX2 is what `the_x86_64_build_has_a_vector_baseline` requires, so the
	# test still proves a vector baseline exists rather than being weakened.

	# the full dependency graph — including inactive optional path deps — so all three
	# siblings must exist on disk even though only two are compiled into the default
	# build. Checked out under the runner's top-level workspace, sibling to this repo's
	# own checkout, exactly as `../../../<repo>` from native/lgj-abi/Cargo.toml expects
	# (matches AdaWorldAPI/lance-graph's own .github/workflows/style.yml pattern).
