Description

Since tap is a security-sensitive feature, we should log uses of tap to the audit log. Given the "secure by default" design goal, this auditing should be enabled in the default configuration. We should use Kubernetes' standard configuration mechanisms (see https://kubernetes.io/docs/tasks/debug-application-cluster/audit/) to control (e.g. allow disabling) of auditing for the tap feature.

Research direction

No files or tests are identified. Start with the Kubernetes audit documentation linked in the issue, then trace the tap feature's invocation path and default configuration; done means every tap invocation is audited, auditing is enabled by default, and Kubernetes-standard configuration can disable it.
