pci-compliance

The code/documentation fragment is largely benign and coherent with its stated goal of PCI DSS guidance. It demonstrates standard best practices for tokenization, data minimization, encryption, access control, and auditing. The main concern is the presence of hardcoded key placeholders and insecure key handling in examples; these are typical in tutorials but must be clearly protected in real implementations (use environment variables or a KMS, do not hardcode secrets). No evidence of malicious behavior or data exfiltration is present in the provided material.
