-A `messaging/` example (create a node, subscribe, send, print received events)
-will be added alongside the Messaging API implementation.

 // Package kernel is the low-level Go wrapper over the logos-delivery Kernel API
 // (libwaku): relay, store, lightpush, filter, peer management, discovery.

-// It mirrors go-waku's shape and predates the Messaging API. It is considered
-// legacy: once logos-delivery#3851 consolidates libwaku and liblogosdelivery
-// into a single tiered library, the kernel surface will be re-pointed at that
-// library and exposed as accessors on the messaging Node rather than as a
-// standalone package. New consumers should prefer the messaging package.
