+# Runs cr_checker (copyright header check) directly from the eclipse-score/tooling
+# repo as a pre-commit hook, instead of via the Bazel `//:copyright` target.
+#
+# Rationale (see https://github.com/eclipse-score/reference_integration/issues/166):
+# the Bazel target pulls in the docs() -> needs_json -> @score_process graph, which
+# fails to resolve because score_process/score_platform are dev_dependencies in the
+# score modules and are therefore invisible when reference_integration aggregates
+# them. The pre-commit hook runs the checker as a standalone script over the repo's
+# files, so it is unaffected by Bazel module resolution.
