Handle edge cases in retry

**Description**
Currently core lacks proper filtering support.

**Proposed solution**
Add configurable filtering with sensible defaults.

**Priority**: Low/Medium

Start by locating the core retry handling in the Operator codebase and identify where filtering decisions are made. The issue does not name files or tests, so first clarify how retry edge cases relate to configurable filtering and define the expected sensible defaults. Done means filtering is configurable and the retry edge cases are covered by appropriate verification.
