 Usage: file_vulnerabilities.py <govulncheck -format json report> <todo.md>

+The item is written the way ~/.claude/bin/rank_todo.py writes one, which CI cannot run:
+todo.md's `Next ID = N` gives its ID, the release of the plan's top row (the next release)
+gives its release, and its Score is todo.md's `Score = …` formula over the scores below and
+the weight todo.md's goal table gives goal 1.1. The test that files into the repository's
+own todo.md fails the gate when the plan's shape drifts from what this script reads.
+
+A security item scores R, S and C 1, since the fix is a version bump, and A and G 8, since a
+known vulnerability in the binaries works against README goal 1.1: installing fejkdata the
+way one installs other tools, which image scanners then flag.
