## Database Schema Additions Needed

```sql
-- Document versions
CREATE TABLE document_versions (
  id UUID PRIMARY KEY,
  document_id UUID REFERENCES documents(id),
  version_number INTEGER,
  content TEXT,
  file_url TEXT,
  created_by UUID,
  created_at TIMESTAMP,
  change_summary TEXT
);

-- Document templates
CREATE TABLE document_templates (
  id UUID PRIMARY KEY,
  name VARCHAR(255),
  category VARCHAR(100),
  template_content TEXT,
  variables JSONB,
  version INTEGER,
  is_active BOOLEAN,
  created_by UUID,
  created_at TIMESTAMP
);

-- Legal matters
CREATE TABLE legal_matters (
  id UUID PRIMARY KEY,
  matter_number VARCHAR(100),
  title VARCHAR(255),
  client_id UUID,
  status VARCHAR(50),
  case_type VARCHAR(100),
  created_at TIMESTAMP,
  updated_at TIMESTAMP
);

-- Matter-document relationships
CREATE TABLE matter_documents (
  matter_id UUID REFERENCES legal_matters(id),
  document_id UUID REFERENCES documents(id),
  relationship_type VARCHAR(50),
  created_at TIMESTAMP
);

-- Document audit log
CREATE TABLE document_audit_log (
  id UUID PRIMARY KEY,
  document_id UUID REFERENCES documents(id),
  action VARCHAR(50),
  performed_by UUID,
  performed_at TIMESTAMP,
  details JSONB
);

-- Document comments
CREATE TABLE document_comments (
  id UUID PRIMARY KEY,
  document_id UUID REFERENCES documents(id),
  version_id UUID REFERENCES document_versions(id),
  comment_text TEXT,
  author_id UUID,
  created_at TIMESTAMP,
  resolved_at TIMESTAMP
);
```

## Service Architecture Recommendations

### New Service: `services/legal-documents/`
- Document template management
- Document versioning
- Document assembly
- Template library

### Enhance: `services/intake/`
- Add document versioning on upload
- Link to matters
- Enhanced classification

### Enhance: `apps/mcp-legal/`
- Matter management UI
- Document management UI
- Filing workflows
- Collaboration features

## Conclusion

**Current State**: Building blocks exist (intake, storage, dataroom) but **no comprehensive law firm/court document management system**.

**Gap**: The system needs significant development to support:
- Document templates and assembly
- Version control and revision history
- Matter management
- Court filing
- Collaboration and workflows

**Priority**: High - This is a critical gap for a legal system.
