📝 Walkthrough

Walkthrough

The ansible_managed variable is relocated from the ansible.cfg file's [defaults] section to group_vars/all.yml, consolidating configuration management directives in the inventory variables rather than the Ansible configuration file.

Changes

Cohort / File(s)	Summary
Configuration Relocation ansible.cfg	Removed the active ansible_managed configuration variable and its explanatory comments from the [defaults] section (−6 lines).
Inventory Variables group_vars/all.yml	Added ansible_managed variable declaration at the top of the file with a management notice (+2 lines).

Poem

🐰 A variable hops from config's nest,
To group_vars where it settles best,
Ansible's managed note takes flight,
Configuration organized just right! ✨
