Global site context. Contains all state managed by a particular site.

The context maps the following keys:

• site-ID: the site’s identifier
• VC: the current vector clock, wrapped in an atom
• CDAG: the current causal directed acyclic graph, wrapped in an atom
• base-FM: the current base feature model, wrapped in an atom
• HB: the current history buffer, wrapped in an atom
• CC: the current conflict cache, wrapped in an atom
• MCGS: the current maximum compatible group set, wrapped in an atom
• combined-effect: the current feature model or conflict descriptor, wrapped in an atom. This is not strictly required, but useful for testing and caching.
• GC: the garbage collector’s current state, wrapped in an atom

The server additionally carries a offline-sites atom that contains sites that have left to be able to prune forwarded messages.

This variable may be rebound to simulate different, interacting sites. On a single site (i.e., in production), the context is not rebound (but modified using atoms).
