Module strategy 

Redaction strategies for anonymizing data.

Each strategy implements a different approach to redacting values:

• null: Replace with NULL
• constant: Replace with a fixed value
• hash: One-way hash (deterministic)
• mask: Partial masking with pattern
• shuffle: Redistribute values within column
• fake: Generate realistic fake data
• skip: No redaction (passthrough)
