+# OpenSSF Scorecard grades the things a reader cannot check by reading the code:
+# whether releases are signed, whether actions are pinned, whether a dangerous
+# workflow trigger is in use, how quickly dependencies are patched. It is the
+# one measure of this repository that is produced by somebody else, which is
+# most of its value -- every other badge here is generated by this project's own
+# CI, and a project grading its own supply chain is the assertion this
+# organisation says it does not accept.
+#
+# The score is published so the badge resolves, and the findings land in the
+# repository's code scanning dashboard beside CodeQL's.
