Module input 

Input validation and sanitization utilities.

This module provides functions for validating and sanitizing user input before processing. These functions are used by import parsers and storage backends to ensure data integrity and security.

Security

Input validation prevents:

• SQL injection via malicious table/column names
• Path traversal via malicious file paths
• Buffer overflows via excessively long inputs
• Unicode normalization attacks

Enums

ValidationError

Errors that can occur during input validation.
