## Waku layer API — message publish primitives used by the messaging send
|
|
## pipeline.
|
|
##
|
|
## Unlike `relay.nim`/`lightpush.nim`, these preserve the rich
|
|
## `WakuLightPushResult` (status code + description) that the send processors
|
|
## branch on for their retry decisions, and expose relay/lightpush availability
|
|
## so the messaging layer never inspects `waku.node` directly.
