+/**
+ * test-arsenal-tools.mjs — guard for the execution bridge (scripts/arsenal-tools.mjs).
+ *
+ * The bridge hands shell-command STRINGS to the hunter's bashTool. The one thing that must
+ * NEVER regress: a value the model controls cannot break out of its single-quoted slot and
+ * inject a second command. Plus structural sanity (schema name == key, valid function-tool
+ * shape, group/selection resolution). Run: `npm run test:arsenal-tools`.
