Summary: When looking in cf-agent -v output, we see traces of prior bundles. This is confusing - and concerning, seems it seems there is some kind of data leakage 
.
We observed this on 3.7.3, and it is still present in 3.10.3.
How to reproduce:
Create a simple policy with two bundles, the first is parameterized and the second not:
bundle agent main {
methods:
"any" usebundle => one("apple");
"any" usebundle => two;
}
bundle agent one (x) {
reports:
"$(x)";
}
bundle agent two {
reports:
"II";
}
Now run it, and you will see that the parameter is reported for the first AND SECOND bundle – even thought the second bundle was NOT parameterized!
