Warning

Review limit reached

@dariemcarlosdev, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 51 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

PR Summary: Multi-IdP Auth Implementation (Adapter/Factory/Strategy)
This PR implements a flexible authentication architecture to support multiple Identity Providers (IdPs) using a combination of design patterns:

Strategy Pattern (IUserProfileService): Defines a common interface for fetching user profiles, allowing the system to switch between different provider-specific implementations at runtime.
Adapter Pattern (Auth0/Cognito/EntraUserProfileService): These services act as adapters, wrapping the specific APIs/responses of different IdPs (Auth0, AWS Cognito, and Azure Entra ID) to conform to the IUserProfileService interface.
Factory Pattern (UserProfileServiceFactory): Encapsulates the instantiation logic, determining which specific IUserProfileService implementation to provide based on the user's authentication context (e.g., the idp claim).

Key Changes:

Introduced IUserProfileService interface.
Implemented specific services for Auth0, Cognito, and Entra ID.
Added UserProfileServiceFactory for dynamic service resolution.
Integrated these services into the IdentityBridgeClaimsTransformation and AccountController to unify user profile handling.
