# when a crate is added: `check-coverage-scope.sh` already reads membership
# from `cargo metadata`, so a stale list fails the coverage gate.

# Usage: scripts/workspace-members.sh packages|dirs
#   packages  package names
#   dirs      manifest directories relative to the repository root ("." for the root)
