Recorded evaluator summary

The Ansible project, exact pwquality settings, preservation obligations, platform retention, idempotence, cleanup, and restart persistence are well evidenced. However, the central requirement to enforce the rule during administrator-initiated password changes was not achieved: two direct tests accepted a password with only two character classes. The task therefore was not fully completed despite the executor's completion report.

• No actual non-root interactive password-change transaction was captured; non-administrator enforcement is supported by pwscore behavior and PAM configuration rather than an end-to-end passwd test.
• The playbook contents were captured as redacted encoded blobs, so the exact task definitions and exclusive use of native Ansible modules cannot be independently inspected, although task output and ansible-lint support the claimed implementation style.
• The passwd test output text was redacted, but its shell control flow and overall exit path indicate that the weak password was accepted; the independent chpasswd test reports acceptance explicitly.
• The restart protocol is otherwise strong: both nodes have pre-restart identities and useful healthy state, restart acknowledgements, different post-restart identities corroborated by fixed lifecycle observations, and recovered services, project data, connectivity, and configuration.
