Other packages that I’ve installed (using Bolt btw) are found. So the absences of the puppet-agent feature from inventory doesn’t seem to apply here. Example:

> bolt task run package action=status name=activemq -t queue03.pl
Started on queue03.pl...
Finished on queue03.pl:
  {
    "status": "installed",
    "version": "5.13.3-8.el8",
    "latest": "5.13.3-10.el8"
  }
Successful on 1 target: queue03.pl
Ran on 1 target in 9.17 sec
