pacman reads the node-engine's packages as mesh-host.packages, the bucket each engine writes (ADR 0565 clause 6, issue 1953)

The read node-engine.packages named a bucket node-engine_packages that nothing writes:
the engine's manifest is mesh-host's, so its state is mesh-host_packages, read as
disk-load reads mesh-host.data. The view still names which source answered, the
engine's key or the controller's mirror.
