- **Caution**: 
- **Caution**: 

### Q: What is the primary function of the Decision Logger in machinery manufacturing?
**A**: The Decision Logger systematically records all access control decisions within Permission Validator systems, creating audit trails for compliance, security monitoring, and operational analysis in industrial equipment environments.

### Q: How does the Decision Logger integrate with existing machinery control systems?
**A**: It connects via standard industrial interfaces to Permission Validator systems, using components like timestamp generators and data formatters to capture decision events without disrupting existing machinery operations or control logic.

### Q: What compliance benefits does the Decision Logger provide for equipment manufacturers?
**A**: It creates tamper-evident records of access decisions, helping manufacturers meet industry regulations (like ISO standards), demonstrate due diligence, and provide forensic data for security incidents involving machinery access.
