+# Mail Manager - Interface Relationships
+
+This document visualizes all the interfaces in the mail_manager module and their relationships.
+
+## Overview
+
+The mail manager uses a hierarchical structure where interfaces are organized by their domain responsibilities:
+- **Common Types**: Base types and selectors
+- **Providers**: Mail service providers (Gmail, IMAP, etc.)
+- **Services**: Individual mail accounts/services
+- **Collections**: Mailboxes and folders
+- **Messages**: Email messages and their parts

+

+    A[SourceSelector] --> B[Provider Level]
+    B --> C[Service Level]
+    C --> D[Collection Level]
+    D --> E[Message Level]
+    
+    B --> B1[ProviderInterface]
+    B --> B2[ProviderCapabilities]

+    E --> E1[MessageInterface]
+    E --> E2[MessageHeaders]
+    E --> E3[MessagePart]
+```
+
+---
+
+## Request/Response Pattern
+
+All operations follow a consistent request/response pattern:
+
+```mermaid
+sequenceDiagram
+    participant Client
+    participant API
+    participant Provider
+    
+    Client->>API: {Operation}Request
+    API->>Provider: Process Request
+    Provider->>API: Data
+    API->>Client: {Operation}Response
+```
+
+### Operations by Level:
+
+**Provider Level:**
+- List, Fetch, Extant
+
+**Service Level:**
+- List, Fetch, Extant, Create, Modify, Destroy
+
+**Collection Level:**
+- List, Fetch, Extant, Create, Modify, Destroy
+
+**Message Level:**
+- List, Fetch, Extant, Create, Modify, Destroy
+
+---
+
+## Capability Inheritance
+
+```mermaid
+graph LR
+    A[ProviderCapabilities] -->|enables| B[ServiceCapabilities]
+    B -->|enables| C[CollectionCapabilities]
+    C -->|enables| D[Message Operations]
+```
+
+Capabilities cascade down the hierarchy - if a provider doesn't support `ServiceList`, then no services can be listed for that provider.
+
+---
+
+## Key Patterns
+
+### 1. **Extends Pattern**
+Response interfaces extend their base interface:
+- `ProviderFetchResponse extends ProviderInterface`
+- `ServiceFetchResponse extends ServiceInterface`
+
+### 2. **Dictionary Pattern**
+List responses use identifier as key:
+```typescript
+{
+  [identifier: string]: Interface
+}
+```
+
+### 3. **SourceSelector Pattern**
+Resources are selected hierarchically:
+```typescript
+{
+  provider: "gmail",
+  service: "user@example.com",
+  collection: "INBOX",
+  message: "msg123"
+}
+```
+
+### 4. **Recursive Structure**
+MessagePart can contain subParts:
+```typescript
+MessagePartInterface {
+  subParts?: MessagePartInterface[]
+}
+```
+
+---
+
+## Usage Examples
+
+### Selecting a specific message:
+```typescript
+const selector: SourceSelector = {
+  provider: "gmail",
+  service: "user@example.com",
+  collection: "INBOX",
+  message: "12345"
+};
+```
+
+### Listing all services for a provider:
+```typescript
+const request: ServiceListRequest = {
+  sources: {
+    provider: "gmail"
+  },
+  range: {
+    offset: 0,
+    limit: 50
+  }
+};
+```
+
+---
+
+## Interface Files
+
+- `common.ts` - Base types and selectors
+- `provider.ts` - Provider-level interfaces
+- `service.ts` - Service-level interfaces
+- `collection.ts` - Collection-level interfaces
+- `message.ts` - Message-level interfaces
