Review comment (bug):
sorry for being pedantic, but just so we do not repeat ourselves later , do you mind amending something like 

```suggestion
// getProbeTimeoutSeconds returns a timeout for how long the probe should work before failing a
// check. The 3-second timeout not only ensures probe reliability across different platforms,
// but also serves as an assertion on the non-functional requirement that the dataplane must
// program network policies within an acceptable latency. This is especially critical for
// network policy features where slow dataplane programming could impact connectivity and security.
// The 3-second threshold was determined through empirical evidence as the maximum acceptable
// latency for network policy enforcement.
```
