+# yarn npm audit reports on a fast-json-patch version < 3.1.1 but due to patch
+# resolution, the only version of fast-json-patch that we use is 3.1.1. We also
+# have 2.2.1 installed but it is a dev only dependency. The "violation" reports
+# smart-transacton-controller as the culprit but if you run
+# `yarn info -A -R dependents fast-json-patch` you can see that only 2.2.1 and
+# 3.3.1 are installed and that smart-transaction-controller resolves to the
+# patched version of 3.3.1. We can remove this once the
+# smart-transaction-controller updates its dependency.
