### Action
`replicas ≥ 2` + readiness probe **if** zero-downtime becomes a formal goal.

---
- **Priority:** 🟢 Low
- **Epic:** #2503

The issue names no file, test, or deployment entry point. First confirm whether zero-downtime is a formal goal, then locate the relevant deployment configuration and define completion as having at least two replicas and a readiness probe when that goal is adopted.
