Module: RailsWayback::RenderProvenance

Defined in:
lib/rails_wayback/render_provenance.rb

Overview

Classifies Action View render identifiers by filesystem origin and normalizes them back to paths relative to the host application. Both the engine logger and toolbar use this module so they cannot drift into applying different provenance rules.
