Add FirstSuccessful, Comparison, and custom (Base) strategies to the MetaProvider, reaching parity with the JS/Go SDK implementations. Resolves open-feature/ruby-sdk#212. Changes: - Refactor inline strategy logic into Strategy pattern (Base, FirstMatch, FirstSuccessful, Comparison) - Add missing fetch_integer_value and fetch_float_value methods - Add track delegation to wrapped providers - Use define_method to DRY up the 6 fetch methods - Bump openfeature-sdk dependency to >= 0.4.0, < 1.0 - Bump version to 0.1.0 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Signed-off-by: Jose Colella <jose.colella@gusto.com>
Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the OpenFeature MetaProvider by introducing a robust strategy pattern for flag evaluation. It expands the provider's capabilities with new 'FirstSuccessful' and 'Comparison' strategies, alongside support for custom evaluation logic. The update also adds comprehensive support for integer and float flag types and ensures event tracking is delegated across all underlying providers, making the MetaProvider more powerful and aligned with other SDKs.

Code Review
This pull request is an excellent improvement, refactoring the MetaProvider to use a Strategy pattern for evaluation. The introduction of FirstSuccessful and Comparison strategies, along with support for custom strategies, significantly enhances the provider's flexibility and brings it to parity with other OpenFeature SDKs. The code is much cleaner and more maintainable, especially with the use of define_method to DRY up the fetch logic. The added tests are comprehensive and the documentation updates are clear and helpful. I have one minor suggestion to improve the clarity of the new Comparison strategy.

The errors array is initialized and populated, but its value is never used. This adds unnecessary complexity and can be confusing for future maintainers. The logic can be simplified by removing the errors array and only collecting successful results, while continuing to ignore providers that return an error or raise an exception.
results = []
providers.each do |provider|
begin
details = fetch_block.call(provider)
results << add_provider_metadata(details, provider) if details.error_code.nil?
rescue StandardError
# Ignore providers that error or raise; they are excluded from comparison.
end
end
