  * Integration Test: Race Results Use Case Orchestration
  * 
  * Tests the orchestration logic of race results page-related Use Cases:
- * - GetRaceResultsUseCase: Retrieves complete race results (all finishers)
- * - GetRaceStatisticsUseCase: Retrieves race statistics (fastest lap, average lap time, etc.)
+ * - GetRaceResultsDetailUseCase: Retrieves complete race results (all finishers)
  * - GetRacePenaltiesUseCase: Retrieves race penalties and incidents
- * - GetRaceStewardingActionsUseCase: Retrieves race stewarding actions
- * - GetRacePointsDistributionUseCase: Retrieves race points distribution
- * - GetRaceChampionshipImplicationsUseCase: Retrieves race championship implications
- * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
- * - Uses In-Memory adapters for fast, deterministic testing
+ * 
+ * Adheres to Clean Architecture:
+ * - Tests Core Use Cases directly
+ * - Uses In-Memory adapters for repositories
+ * - Follows Given/When/Then pattern
  * 
  * Focus: Business logic orchestration, NOT UI rendering

- * - GetRaceDetailUseCase: Retrieves race details for navigation
- * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
- * - Uses In-Memory adapters for fast, deterministic testing

  * Integration Test: Sponsor Billing Use Case Orchestration
- *

  * Tests the orchestration logic of sponsor billing-related Use Cases:
- * - GetBillingStatisticsUseCase: Retrieves billing statistics
- * - GetPaymentMethodsUseCase: Retrieves payment methods
- * - SetDefaultPaymentMethodUseCase: Sets default payment method
- * - GetInvoicesUseCase: Retrieves invoices
- * - DownloadInvoiceUseCase: Downloads invoice
- * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
+ * - GetSponsorBillingUseCase: Retrieves sponsor billing information
+ * - Validates that Use Cases correctly interact with their Ports (Repositories)
  * - Uses In-Memory adapters for fast, deterministic testing
- *

  * Focus: Business logic orchestration, NOT UI rendering

 /**
  * Integration Test: Sponsor Campaigns Use Case Orchestration
- * 
+ *
  * Tests the orchestration logic of sponsor campaigns-related Use Cases:
- * - GetSponsorCampaignsUseCase: Retrieves sponsor's campaigns
- * - GetCampaignStatisticsUseCase: Retrieves campaign statistics
- * - FilterCampaignsUseCase: Filters campaigns by status
- * - SearchCampaignsUseCase: Searches campaigns by query
- * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
+ * - GetSponsorSponsorshipsUseCase: Retrieves sponsor's sponsorships/campaigns
+ * - Validates that Use Cases correctly interact with their Ports (Repositories)
  * - Uses In-Memory adapters for fast, deterministic testing
- * 
+ *
  * Focus: Business logic orchestration, NOT UI rendering

  * Integration Test: Sponsor Leagues Use Case Orchestration
- * 
+ *
  * Tests the orchestration logic of sponsor leagues-related Use Cases:
- * - GetAvailableLeaguesUseCase: Retrieves available leagues for sponsorship
- * - GetLeagueStatisticsUseCase: Retrieves league statistics
- * - FilterLeaguesUseCase: Filters leagues by availability
- * - SearchLeaguesUseCase: Searches leagues by query
- * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
+ * - GetSponsorSponsorshipsUseCase: Retrieves sponsor's sponsorships/campaigns
+ * - Validates that Use Cases correctly interact with their Ports (Repositories)
  * - Uses In-Memory adapters for fast, deterministic testing
- * 
+ *
  * Focus: Business logic orchestration, NOT UI rendering

  * Integration Test: Team Detail Use Case Orchestration
  * 
  * Tests the orchestration logic of team detail-related Use Cases:
- * - GetTeamDetailUseCase: Retrieves detailed team information including roster, performance, achievements, and history
- * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
+ * - GetTeamDetailsUseCase: Retrieves detailed team information including roster and management permissions
+ * - Validates that Use Cases correctly interact with their Ports (Repositories)
  * - Uses In-Memory adapters for fast, deterministic testing
  * 
  * Focus: Business logic orchestration, NOT UI rendering

  * Integration Test: Teams List Use Case Orchestration
  * 
  * Tests the orchestration logic of teams list-related Use Cases:
- * - GetTeamsListUseCase: Retrieves list of teams with filtering, sorting, and search capabilities
- * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
+ * - GetAllTeamsUseCase: Retrieves list of teams with enrichment (member count, stats)
+ * - Validates that Use Cases correctly interact with their Ports (Repositories)
  * - Uses In-Memory adapters for fast, deterministic testing
  * 
  * Focus: Business logic orchestration, NOT UI rendering
