This module provides middleware components for the FastAPI backend:
- Request-ID: Adds unique request identifiers for tracing
- Security Headers: Adds security headers to all responses
- Rate Limiter: Protects against abuse (Valkey-based)
- PII Redactor: Redacts sensitive data from logs
- Input Gate: Validates request body size and content types
