 ## Packages
 
+Adopt only what you need — every package is independently versioned and focused on a single concern.
+
+**Core**
+
+| Package | Description |
+|---|---|
+| **Vulthil.Results** | Result primitives for explicit success/failure flows without exceptions. |
+| **Vulthil.SharedKernel** | Domain primitives — aggregate roots, entities, domain events, and domain exceptions. |
+
+**Application & API**
+
+| Package | Description |
+|---|---|
+| **Vulthil.SharedKernel.Application** | CQRS handlers, pipeline behaviors, and FluentValidation integration. |
+| **Vulthil.SharedKernel.Api** | Minimal-API endpoint helpers and `Result`-to-HTTP conversion. |
+
+**Persistence & Outbox**
+
+| Package | Description |
+|---|---|
+| **Vulthil.SharedKernel.Outbox** | Transactional domain-event outbox engine; persistence-agnostic. |
+| **Vulthil.SharedKernel.Outbox.EntityFrameworkCore** | EF Core implementation of the domain-event outbox. |
+| **Vulthil.SharedKernel.Infrastructure** | EF Core persistence, transactions, and outbox wiring. |
+| **Vulthil.SharedKernel.Infrastructure.Relational** | Shared relational helpers for the provider packages. |
+| **Vulthil.SharedKernel.Infrastructure.Npgsql** | PostgreSQL/Npgsql EF Core mappings and optimizations. |
+| **Vulthil.SharedKernel.Infrastructure.MySql** | MySQL EF Core mappings and optimizations. |
+| **Vulthil.SharedKernel.Infrastructure.Cosmos** | Azure Cosmos DB EF Core mappings and optimizations. |
+
+**Messaging**
+
+| Package | Description |
+|---|---|
+| **Vulthil.Messaging.Abstractions** | Contracts for producers, consumers, and request/reply boundaries. |
+| **Vulthil.Messaging** | Composition APIs for consumers, queues, and hosted processing. |
+| **Vulthil.Messaging.RabbitMq** | RabbitMQ transport for the messaging abstractions. |
+| **Vulthil.Messaging.Outbox** | Transactional bus-publish outbox that eliminates the dual-write problem. |
+| **Vulthil.Messaging.Inbox** | Idempotent-receiver (inbox) consume filter for exactly-once processing. |
+| **Vulthil.Messaging.Inbox.EntityFrameworkCore** | Shared EF Core primitives for the inbox idempotency store. |
+| **Vulthil.Messaging.Inbox.Relational** | Relational EF Core idempotency store (transactional exactly-once). |
+| **Vulthil.Messaging.Inbox.Cosmos** | Azure Cosmos DB idempotency store (effectively-once). |
+| **Vulthil.Messaging.TestHarness** | In-memory harness for asserting messaging flows in tests. |
+
+**Hosting & Testing**
