Luna's report

The observed run reported no behaviour findings, and our code review judged plugins/flow.js benign. Pin the scanned version. Behaviour outside the observed install and entry windows was not verified.

We installed the package and ran its entry point in a throwaway sandbox, and scanned the code. The run produced no reported behaviour findings; static scanners did not complete.
