What
A message-kind resolver that used to special-case only the peer kind now also handles a coordinator kind. Like peer, a coordinator message can carry an optional plugin identifier through to the resulting notification object.
Why
This lets notifications distinguish messages coming from a coordinator role, not just from peers, while still preserving which plugin the message relates to.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what a coordinator is in this context or what triggers a coordinator-kind message.
