Overview

Regression: PaperTrail (>= 13) deserializes versions.object_changes via YAML.safe_load, using ActiveRecord.yaml_column_permitted_classes as the allow-list. Rails 7's default is [Symbol], so any update that touches updated_at (an ActiveSupport::TimeWithZone) raises Psych::DisallowedClass inside version.changeset, and PaperTrail rescues that into {}. The inline_forms versions list then renders every changeset as empty.

The installer ships config/initializers/paper_trail_yaml_safe_load.rb, which extends the allow-list. This test fails if that initializer is missing or insufficient.
