 The context object passed into a rule provides access to utility functions and metadata that the schematic may need to work with, including a logging API to help with debugging.
 The context also defines a *merge strategy* that determines how changes are merged from the staged tree into the base tree. A change can be accepted or ignored, or throw an exception.
