WalkthroughThe controller now initializes node health before starting pod workers. It handles Ready-to-Unknown transitions as not-ready transitions, retries pod processing, and records ChangesNode health transitions
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to If initial node health monitoring fails, pod workers can start with no node health data and permanently drop startup pod events, leaving workloads unprocessed. The change is not merge-ready until worker startup is prevented or retried when initialization fails. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Stop worker startup when initial health monitoring fails.
If monitorNodeHealth fails at Line 461, Run starts pod workers with an empty nodeHealthMap. processPod then returns without requeue for each startup Add event. A later periodic health pass cannot replay those dropped events. Return or retry before starting workers.
Proposed fix
if err := nc.monitorNodeHealth(ctx); err != nil {
logger.Error(err, "Error monitoring node health")
+ return
