Besides `++ze`, this directly :: contains the logic for commiting new revisions (local urbits), managing :: and notifying subscribers (reactivity), and pulling and validating content :: (remote urbits). :: :: The state includes: :: :: -- local urbit `our` :: -- current time `now` :: -- current duct `hen` :: -- scry handler `ski` :: -- all vane state `++raft` (rarely used, except for the object store) :: -- target urbit `her` :: -- target desk `syd` :: :: For local desks, `our` == `her` is one of the urbits on our pier. For :: foreign desks, `her` is the urbit the desk is on and `our` is the local :: urbit that's managing the relationship with the foreign urbit. Don't mix :: up those two, or there will be wailing and gnashing of teeth. :: :: While setting up `++de`, we check if `our` == `her`. If so, we get :: the desk information from `dos.rom`. Otherwise, we get the rung from :: `hoy` and get the desk information from `rus` in there. In either case, :: we normalize the desk information to a `++rede`, which is all the :: desk-specific data that we utilize in `++de`. Because it's effectively :: a part of the `++de` state, let's look at what we've got: :: :: -- `lim` is the most recent date we're confident we have all the :: information for. For local desks, this is always `now`. For foreign :: desks, this is the last time we got a full update from the foreign :: urbit. :: -- `ref` is a possible request manager. For local desks, this is null. :: For foreign desks, this keeps track of all pending foreign requests :: plus a cache of the responses to previous requests. :: -- `qyx` is the set of subscriptions, with listening ducts. These :: subscriptions exist only until they've been filled. :: -- `dom` is the actual state of the filetree.
