Start by locating the production namespace manifests and the Patroni deployment configuration, then identify the other services that may need Pod Disruption Budgets. Review the linked architecture video and confirm whether anti-affinity is required; done means the agreed PDBs and any required scheduling rules are applied and verified against the acceptance criteria.
