Defined in:
lib/statecraft/errors.rb

Overview

A question (can_fire?, may_?, available_) was asked without metadata while an input_guard stands on the consulted path — its answer without the input would be a false "no", so the question refuses loudly instead. An explicit metadata: {} states "my input is empty" and is legal.
