Has Functionality Implementation

This PR implements comprehensive authorization checking capabilities for the Ruby SDK.

What's Added

Core Methods:

• has_roles?, has_permissions?, has_feature_flags?, has_billing_entitlements? - Individual authorization checks
• has() - Unified method for checking multiple conditions at once

Advanced Features:

• Complex Conditions: Custom Ruby blocks for sophisticated authorization logic
• Force API Control: Choose between token-cached or fresh API data
• Early Exit Optimization: Stops checking on first failure for better performance
• Flexible Input: Supports arrays, single strings, symbols, and string keys

Usage Examples

Simple checks

client.has_roles?(['admin', 'user'])
client.has_permissions?('read:users')

Unified authorization

client.has(
roles: ['admin'],
permissions: ['read:users'],
feature_flags: ['dark_mode']
)

Complex conditions

client.has_roles?([
'admin',
{ role: 'manager', condition: ->(r) { r[:level] == 'senior' } }
])

Great work 🎉 This PR introduces a powerful unified has() method with excellent examples, tests, and cross-SDK compatibility. The implementation is production-ready.

Strengths

• Comprehensive coverage (roles, permissions, flags, entitlements)
• Flexible force API parameter handling
• Early exit optimization for performance
• 191 lines of examples + dedicated test coverage
• Consistent with PHP/JS SDKs

Recommendations

1. has() method is long (~80 lines) → consider breaking into helper methods.
2. Add more granular error handling (API errors vs. argument errors).
3. Potential performance gain via caching/memoization.
4. Inline documentation/examples could make the API even clearer.

Verdict: High-quality PR 🚀 — just a few refactor and maintainability suggestions.

📊 Test Results Summary

Component	Implementation	Documentation	Testing	Cross-SDK
Unified has() Method	✅	✅	✅	✅
Complex Conditions	✅	✅	✅	✅
Force API Control	✅	✅	✅	✅
Examples File	✅	✅	N/A	✅
Test Coverage	✅	N/A	✅	N/A

Overall Score: 5/5 components - EXCELLENT implementation

Key Metrics:

• Lines Added: 1,099 lines (comprehensive implementation)
• Files Changed: 6 files (well-organized changes)
• Examples: 191 lines of detailed usage examples
• Test Coverage: Dedicated test file included
• Cross-SDK Compatibility: Full PHP and JavaScript SDK support

Areas for Enhancement:

1. Method Complexity: The has() method could be refactored into smaller helper methods
2. Error Handling: Could be more granular for different error types
3. Performance: Consider caching for frequently accessed authorization data
4. Unit Testing: Could benefit from more granular unit tests

This PR significantly enhances the Ruby SDK's authorization capabilities with a sophisticated unified method. The implementation is production-ready and includes excellent documentation and examples. The complexity of the main method is the primary area for improvement.

🚀 Next Steps

1. Refactor Method Complexity: Break the has() method into smaller helper methods
2. Enhanced Error Handling: Add more granular error handling for different scenarios
3. Performance Optimization: Consider caching strategies for authorization data
4. Integration Testing: Test with real Kinde instances and complex scenarios
5. Release Planning: Consider version bump and changelog updates

[ZulqarnainNazir]

Error handling is good, but you might want to differentiate API errors vs. invalid arguments vs. unexpected exceptions. That way, debugging is easier in production.

[ZulqarnainNazir]

Nice flexibility here 👏. One idea: memoize or cache results if this gets called frequently in a hot path, to avoid recomputing hash merges.

[ZulqarnainNazir]

This method is ~80 lines and handles multiple responsibilities. Consider breaking out role/permission/flag/entitlement checks into private helpers (e.g., check_roles_condition) for readability and testability
