What problem does it solve? Developers working on the GameHub platform need project-specific knowledge about its domain model, business rules, EAF/ABP conventions, and end-to-end test setup that generic C# or Angular guidance cannot provide. ## Core Features & Use Cases - Domain Reference: Lists aggregate roots, entities, value objects, and enums such as Game, GameBuild, LeaderboardEntry, and ModerationReview. - Business Rules: Encodes publishing constraints, such as requiring an Approved build and an index.html entry point under 100 MB without executables. - E2E Test Guidance: Documents Docker infrastructure setup, migrator commands, SignalR token negotiation, Playwright selectors, and known Angular test workarounds. - Use Case: When adding a new entity to GameHub, follow the documented pattern of inheriting FullAuditedAggregateRoot<Guid>, registering a DbSet in GameHubDbContext, and configuring mappings in GameHubModelCreatingExtensions. ## Quick Start Ask the assistant to implement a new GameHub application service following the platform's EAF/ABP conventions and business rules.
