-- novox/hq 09-the-node-lifecycle: the host reports what it owns and the mesh keeps the last
-- report. **This is a backup, never a source.** The host never reads it to decide anything; it is
-- handed back only when a node has lost its own store, and a node that disagrees with it wins,
-- because the node is the one that can see the machine.
--
-- Its point is the orphans. A node that loses its state file currently strands whatever it had
-- applied: nothing on the machine knows those resources were ever the mesh's doing, so nothing
-- removes them. With this, a rebuilt node receives both the declaration and the record of what it
-- previously owned, and can take away what is no longer declared.

-- When that report arrived. Separate from last_seen, which moves on any word from the node at
-- all: a node can be plainly alive for weeks without applying anything, and reading one as the
-- other would make a quiet node look like a stale one.
