OCI_Build uses id_ed25519 (faster, shorter, more secure). RSA is weaker and inconsistent with the rest of the homelab. On a fresh Ansible machine id_rsa may not exist, causing silent auth failure.
Fix
Update to the dedicated unifi key once the SSH hardening issue is resolved:
## Problem
```yaml
ansible_ssh_private_key_file: ~/.ssh/id_rsa
```
