### **Cognify API Endpoints Covered**
Based on OpenAPI analysis:
- `POST /api/v1/collections/` - Create collection
- `GET /api/v1/collections/` - List collections
- `GET /api/v1/collections/{id}` - Get collection details
- `DELETE /api/v1/collections/{id}` - Delete collection

- `GET /api/v1/collections/{id}/status` - Collection status
- `GET /api/v1/collections/{id}/documents` - Collection documents
- `GET /api/v1/collections/{id}/collaborators` - Collaborators
- `POST /api/v1/collections/{id}/collaborators` - Add collaborator
- `GET /api/v1/collections/{id}/analytics` - Collection analytics

## 🏗️ **IMPLEMENTATION STRATEGY**

### **Step 1: Collection Models**
```python
# collections/models.py
from pydantic import BaseModel
from typing import Optional, List, Dict, Any
from datetime import datetime
from enum import Enum

class CollectionVisibility(str, Enum):
    PRIVATE = "private"
    ORGANIZATION = "organization"
    WORKSPACE = "workspace"
    PUBLIC = "public"

class CollaboratorRole(str, Enum):
    VIEWER = "viewer"
    CONTRIBUTOR = "contributor"
    EDITOR = "editor"
    ADMIN = "admin"

class Collection(BaseModel):
    id: str
    name: str
    description: Optional[str] = None
    visibility: CollectionVisibility
    owner_id: str
    organization_id: Optional[str] = None
    workspace_id: Optional[str] = None
    document_count: int = 0
    total_size: int = 0
    created_at: datetime
    updated_at: datetime
    metadata: Dict[str, Any] = {}

class Collaborator(BaseModel):
    user_id: str
    email: str
    name: str
    role: CollaboratorRole
    added_at: datetime
    added_by: str
    permissions: List[str] = []

class CollectionStats(BaseModel):
    collection_id: str
    document_count: int
    total_size_bytes: int
    processing_status: Dict[str, int]
    last_activity: datetime
    query_count_30d: int
    top_contributors: List[Dict[str, Any]]
    popular_documents: List[Dict[str, Any]]
```

### **Step 2: Collections Module**
```python
# collections/collections_module.py
class CollectionsModule:
    def __init__(self, client: 'CognifyClient'):
        self.client = client
    
    # Collection Management
    async def create(
        self,
        name: str,
        description: Optional[str] = None,
        visibility: CollectionVisibility = CollectionVisibility.PRIVATE,
        workspace_id: Optional[str] = None,
        metadata: Optional[Dict[str, Any]] = None
    ) -> Collection:
        """Create a new collection"""
    
    async def list(
        self,
        workspace_id: Optional[str] = None,
        visibility: Optional[CollectionVisibility] = None,
        limit: int = 50,
        offset: int = 0
    ) -> List[Collection]:
        """List collections with filtering"""
    
    async def get(self, collection_id: str) -> Collection:
        """Get collection by ID"""
    
    async def update(
        self,
        collection_id: str,
        name: Optional[str] = None,
        description: Optional[str] = None,
        visibility: Optional[CollectionVisibility] = None,
        metadata: Optional[Dict[str, Any]] = None
    ) -> Collection:
        """Update collection details"""
    
    async def delete(self, collection_id: str) -> bool:
        """Delete collection"""
    
    async def search(
        self,
        query: str,
        workspace_id: Optional[str] = None,
        visibility: Optional[CollectionVisibility] = None,
        limit: int = 50
    ) -> List[Collection]:
        """Search collections"""
```

### **Step 3: Collaboration Management**
```python
# collections/collaboration.py
class CollaborationModule:
    def __init__(self, collections_module: CollectionsModule):
        self.collections = collections_module
    
    async def get_collaborators(
        self,
        collection_id: str
    ) -> List[Collaborator]:
        """Get list of collaborators for a collection"""
    
    async def add_collaborator(
        self,
        collection_id: str,
        email: str,
        role: CollaboratorRole = CollaboratorRole.VIEWER,
        permissions: Optional[List[str]] = None
    ) -> Collaborator:
        """Add a collaborator to a collection"""
    
    async def update_collaborator(
        self,
        collection_id: str,
        user_id: str,
        role: Optional[CollaboratorRole] = None,
        permissions: Optional[List[str]] = None
    ) -> Collaborator:
        """Update collaborator role and permissions"""
    
    async def remove_collaborator(
        self,
        collection_id: str,
        user_id: str
    ) -> bool:
        """Remove a collaborator from a collection"""
    
    async def get_user_permissions(
        self,
        collection_id: str,
        user_id: Optional[str] = None
    ) -> List[str]:
        """Get user permissions for a collection"""
```

### **Step 4: Analytics & Insights**
```python
# collections/analytics.py
class CollectionAnalytics:
    def __init__(self, collections_module: CollectionsModule):
        self.collections = collections_module
    
    async def get_collection_stats(
        self,
        collection_id: str
    ) -> CollectionStats:
        """Get detailed statistics for a collection"""
    
    async def get_collection_status(
        self,
        collection_id: str
    ) -> Dict[str, Any]:
        """Get collection processing status and health"""
    
    async def get_collection_documents(
        self,
        collection_id: str,
        limit: int = 50,
        offset: int = 0,
        doc_status: Optional[str] = None,
        document_type: Optional[str] = None
    ) -> List[Dict[str, Any]]:
        """Get documents in a collection"""
    
    async def get_usage_analytics(
        self,
        collection_id: str,
        days_back: int = 30
    ) -> Dict[str, Any]:
        """Get usage analytics for a collection"""
```

        name="Test Collection",
        description="Test description"
    )
    assert collection.id
    assert collection.name == "Test Collection"

async def test_collaboration():
    collection = await client.collections.create("Test Collection")
    
    # Add collaborator
    collaborator = await client.collections.add_collaborator(
        collection.id,
        email="test@example.com",
        role=CollaboratorRole.CONTRIBUTOR
    )
    
    # Get collaborators
    collaborators = await client.collections.get_collaborators(collection.id)
    assert len(collaborators) >= 1
    assert any(c.email == "test@example.com" for c in collaborators)

async def test_permissions():
    collection = await client.collections.create("Test Collection")
    
    # Check owner permissions
    permissions = await client.collections.get_user_permissions(collection.id)
    assert "admin" in permissions or "owner" in permissions
```

### **Integration Tests**
```python
async def test_collection_workflow():
    # Create collection
    collection = await client.collections.create("Integration Test")
    
    # Upload document to collection
    document = await client.documents.upload(
        "test_file.py",
        collection_id=collection.id
    )
    
    # Get collection stats
    stats = await client.collections.get_collection_stats(collection.id)
    assert stats.document_count >= 1
    
    # Search in collection
    results = await client.query.search(
        "test content",
        collection_id=collection.id
    )
    
    # Clean up
    await client.collections.delete(collection.id)
```

### **Security Tests**
- Permission boundary testing
- Access control validation
- Collaboration security
- Data isolation verification

## 📚 **DOCUMENTATION**

### **Collections Guide**
```python
# Create and manage collections
from cognify_sdk import CognifyClient, CollectionVisibility, CollaboratorRole

client = CognifyClient(api_key="your_key")

# Create a collection
collection = await client.collections.create(
    name="My Project",
    description="Main project codebase",
    visibility=CollectionVisibility.ORGANIZATION
)

# Add team members
await client.collections.add_collaborator(
    collection.id,
    email="developer@company.com",
    role=CollaboratorRole.CONTRIBUTOR
)

await client.collections.add_collaborator(
    collection.id,
    email="manager@company.com",
    role=CollaboratorRole.VIEWER
)

# Upload documents
await client.documents.upload(
    "src/main.py",
    collection_id=collection.id
)

# Get insights
stats = await client.collections.get_collection_stats(collection.id)
print(f"Collection has {stats.document_count} documents")
print(f"Top contributors: {stats.top_contributors}")
```

### **Organization Management**
```python
# Work with organizational collections
org_collections = await client.collections.list(
    visibility=CollectionVisibility.ORGANIZATION
)

# Search across organization
results = await client.collections.search(
    "authentication implementation",
    visibility=CollectionVisibility.ORGANIZATION
)

# Get team analytics
for collection in org_collections:
    stats = await client.collections.get_collection_stats(collection.id)
    print(f"{collection.name}: {stats.query_count_30d} queries this month")
```

## 🔄 **RISK MITIGATION**

### **Security Risks**
- **Access Control**: Comprehensive permission testing
- **Data Isolation**: Multi-tenant security validation
- **Collaboration**: Secure invitation and access management

### **Performance Risks**
- **Large Collections**: Efficient pagination and filtering
- **Analytics**: Caching and optimization
- **Concurrent Access**: Proper locking and consistency
