Module: Oselvar::Var::Core::Conformance

Defined in:
lib/oselvar/var/core/conformance.rb

Overview

Projections from the internal pipeline values to the camelCase wire dicts compared against golden/*.json. Port of conformance.ts. (var-doc stage; registry/plan/trace projections are added in later stages.)
