A node's plans took 2.6-13.6 s of CPU on the provisioner: one composition
resolved every machine of the mesh some two hundred times (who is on the
private network, and the rest of the mesh, worked out again on every
look), three compositions did so again each, and the holder composed
twice. A composer now works each out once over its unchanging Input;
Composing gives Resolve, Render and Generators one composer;
PlansHeldTwice composes the wanted and the newest builds over one read of
the bus, says where the time went by phase, and the states reader keeps a
build's take-in by its content. WatchedStates takes a process's own
writes into the copy at once, so a holder reads its own states from it.
Measured on a captured novox mesh: 11.7 s to 0.49 s per composition of an
unchanged node, plans and provisions identical on all four nodes.

The node key <node>.node is a write's commit: it names each placed module with its value's digest, the
module keys carry the value they replace until it lands, so a reader never composes half a write. Every
reader goes through PlacementKeys/PlacementsOf, which read the legacy placement.<node> too while the
change is delivered.
