• Replace the rails gem dependency with separate railties and activesupport dependencies at >= 8.0.0

test/dummy/config/application.rb:3

• The dummy app now requires rails/all, but the gemspec no longer depends on the rails gem. This mismatched dependency will cause load failures. You should either re-add the rails gem dependency or revert to requiring the specific railties you need.

require "rails/all"

rails-app_env.gemspec:27

• The gemspec defines dependencies on railties and activesupport but omits the rails gem, which may be required by some parts of the code (e.g., rails/all). Ensure dependencies align with the frameworks your code actually loads.

[Copilot]

[nitpick] Using an open-ended >= 8.0.0 constraint may allow unintended major-version upgrades that introduce breaking changes. Consider using a pessimistic constraint (e.g., ~> 8.0) or adding an upper bound (< 9.0.0).

Suggested change

	rails_version = ">= 8.0.0"
	rails_version = ">= 8.0.0, < 9.0.0"
