Global Ansible credentials, applied to every run (manual + alert-triggered): - core/settings.py: ansible.ssh_private_key / become_password / vault_password (plaintext at rest, masked in UI — encryption tracked in #580) + host_key_checking (default off); surfaced via to_ansible_cfg into app.config[ANSIBLE] - executor.py: pure build_credentials() materializes creds into a 0600 temp dir (--private-key, --vault-password-file, become via -e @vars-file so the password never hits argv) cleaned up in finally; pure ansible_env() sets ANSIBLE_HOST_KEY_CHECKING. build_ansible_command stays param-only - settings/routes.py + ansible.html: admin-only Credentials section, masked-update (blank keeps current, explicit Clear checkbox), reload app config on save - tests: unit (build_credentials per cred + none; ansible_env toggle); integration vault round-trip (ansible-vault encrypt a vars file, run via executor with the vault password, assert it decrypted) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
