Walkthrough

This pull request restructures the domain model by replacing the IsFromBot property with a Role property on messages, introduces domain-level constants and enums, removes the specification pattern and domain services, adds Entity Framework Core configurations and migrations, enhances exception handling middleware, and includes VSCode debugging configuration.

Changes

Cohort / File(s) Summary
VSCode Configuration
​.vscode/launch.json, ​.vscode/tasks.json
Adds VSCode debugging and task execution configurations for .NET Core development, including build, publish, watch, clean, and restore tasks; defines launch profiles for Web.Api with environment variables and Swagger integration.
Documentation
​file_tree.md
Auto-generated project structure documentation enumerating directories and files across Application, Domain, Infrastructure, and Web.Api layers.
Domain Constants
​src/Domain/Constants/MessageRoles.cs
Introduces public MessageRoles constants (User, Assistant) and validation helper; UserRoles.cs documentation removed.
Domain Enums
​src/Domain/Enums/ConversationStatus.cs, ​src/Domain/Enums/MessageType.cs
Adds ConversationStatus enum (Active, Closed, Archived, Suspended) and MessageType enum (Text, Image, Document, Audio, System, LegalAdvice) to centralize domain definitions.
Domain Entity Redesign
​src/Domain/Entities/Message.cs, ​src/Domain/Entities/Conversation.cs
Message: removes IsFromBot, adds Role property (default User); replaces type-based checks with IsFromAssistant()/IsFromUser() methods. Conversation: removes Priority property; moves ConversationStatus enum to Domain.Enums.
Domain Aggregate Updates
​src/Domain/Aggregates/Conversation/ConversationAggregate.cs
Replaces Entities.Message/Entities.MessageType with direct imports; removes priority calculation logic; maps isFromBot to Role property (MessageRoles.Assistant/User).
Domain Code Removal
​src/Domain/Services/ConversationDomainService.cs, ​src/Domain/Services/UserDomainService.cs, ​src/Domain/Specifications/ISpecification.cs, ​src/Domain/Specifications/CompositeSpecifications.cs, ​src/Domain/Specifications/ConversationSpecifications.cs, ​src/Domain/Specifications/UserSpecifications.cs, ​src/Domain/Events/Examples/DomainEventsUsageExamples.cs, ​src/Domain/Specifications/Examples/SpecificationUsageExamples.cs
Removes specification pattern infrastructure, domain services, and example documentation files; eliminates deprecated business logic for priority calculation and role/permission enforcement.
Application Layer
​src/Application/Common/Behaviors/LoggingBehavior.cs
Modifies exception handling to conditionally bypass wrapping for ApplicationException types; preserves original exception types while wrapping non-application exceptions.
Infrastructure EF Core Configuration
​src/Infrastructure/Data/Configurations/UserConfiguration.cs, ​src/Infrastructure/Data/Configurations/ConversationConfiguration.cs, ​src/Infrastructure/Data/Configurations/MessageConfiguration.cs
Adds fluent EF Core entity configurations mapping User, Conversation, Message to database tables with constraints, relationships, indexes, soft-delete filters, and value conversions (e.g., roles as comma-separated string).
Database Context
​src/Infrastructure/Data/Contexts/DataContext.cs
Exposes public DbSet<User>, DbSet<Conversation>, DbSet<Message> properties.
Database Migrations
​src/Infrastructure/Data/Migrations/20251027072923_InitialSchema.cs, ​src/Infrastructure/Data/Migrations/20251027072923_InitialSchema.Designer.cs, ​src/Infrastructure/Data/Migrations/DataContextModelSnapshot.cs
Adds initial PostgreSQL schema with Users, Conversations, Messages tables; includes indexes, foreign keys, constraints, and soft-delete support.
API Exception Handling
​src/Web.Api/Middleware/GlobalExceptionMiddleware.cs
Refactors exception-to-response mapping into centralized GetExceptionDetails() method; unwraps RequestProcessingException inner exceptions; maps custom exceptions (ValidationException, UnauthorizedException, etc.) to specific HTTP status codes and error structures.
Project Configuration
​src/Web.Api/Web.Api.csproj
Adds Microsoft.EntityFrameworkCore.Design (8.0.11) NuGet package reference.
Application Configuration
​src/Web.Api/appsettings.json, ​src/Web.Api/appsettings.Development.json
Updates PostgreSQL connection string to remote host; removes Redis connection; removes Development-specific connection string override.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~50 minutes

  • High-density logic areas:

    • Message entity redesign with Role property and method replacements (Message.cs) — requires verification of all call sites
    • Exception middleware refactoring with centralized mapping logic (GlobalExceptionMiddleware.cs)
    • UserConfiguration with role list serialization and value comparison logic
  • Structural complexity:

    • Removal of specification pattern across multiple files — verify no orphaned dependencies remain
    • Removal of domain services — ensure logic is not duplicated elsewhere or left unimplemented
  • Infrastructure changes:

    • EF Core configurations with relationships, constraints, and soft-delete filters — verify schema matches entity definitions and migrations
    • Initial migration with multiple tables and indexes — cross-check for consistency with configurations
  • Areas requiring extra attention:

    • Message role model migration: verify all IsFromBot usages are replaced with Role property checks
    • Conversation aggregate: ensure priority removal doesn't break existing business logic
    • Exception handling: confirm RequestProcessingException unwrapping doesn't mask important context
    • Database migration: validate foreign key relationships and cascade/restrict delete behaviors match intended semantics

🐰 Hop into the refactor with glee,
Message roles now clear to see,
Specs are gone, exceptions caught,
Domain models freshly wrought!
Database schema, neat and tight,
Your architecture shines so bright!
