-// getProbeTimeoutSeconds returns a timeout for how long the probe should work before failing a check, and takes windows heuristics into account, where requests can take longer sometimes.
+// 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.
