Rails 7.2 / Mongoid 8: slug_caching test failure in Catalog::ProductTest

[kitcommerce]

Problem

Workarea::Catalog::ProductTest#test_slug_caching fails under Rails 7.2 + Mongoid 8:

Failure:
Workarea::Catalog::ProductTest#test_slug_caching [testing/lib/workarea/core/navigable_test.rb:40]:
Expected: "different-slug"
  Actual: "same-slug"

Root Cause (suspected)

Mongoid 8 changed how dirty tracking and document-level caching works for fields that implement slug generation. The navigable_test.rb tests expect that saving a record with a new name generates a new slug, but Mongoid 8's caching may be returning the original slugified value.

Files Involved

• testing/lib/workarea/core/navigable_test.rb:28-40
• core/app/models/workarea/catalog/product.rb (slug field definition)
• Mongoid slug generation logic

Next Steps

1. Review Mongoid 8 changelog for dirty tracking / slug behavior changes
2. Check if Mongoid::Slug or equivalent needs updating
3. Fix or adapt the test to match correct Mongoid 8 behavior

Observed in

Rails 7.2 test suite appraisal (issue #768).

Client Impact: None (test/model infrastructure)
