We need to parse policy snippets. They are dated: 2024-01, 2025-06, 2026-05. They specify backup retention periods. The question: "For a production system today, what retention rule applies and why?" Today presumably 2026-06-16 (current date). The policies are:

- 2024-01: Backups are retained 14 days.
- 2025-06: Backups are retained 30 days.
- 2026-05: Backups are retained 45 days for production systems.

We need to determine which rule applies. The policies likely override earlier ones. The most recent policy that applies to production systems is 2026-05: 45 days. So for a production system today, the retention rule is 45 days because the policy from 2026-05 is the latest and specifically mentions production systems. The earlier policies are superseded by later ones. So answer: 45 days. Provide reasoning: because the most recent policy that applies to production systems overrides earlier ones. Also mention that the 2026-05 policy is the latest and applies to production systems, so that is the rule. Also note that the earlier policies are superseded. So answer accordingly.
