Mock Data Generator — illustrative example

INPUT
Generate two fictional orders with unique order_id, valid customer_id and nonnegative amount. Allowed customer IDs: SYN-C1, SYN-C2. Include a zero amount.

RESULT
[
  {"order_id": "SYN-O1", "customer_id": "SYN-C1", "amount": 0},
  {"order_id": "SYN-O2", "customer_id": "SYN-C2", "amount": 24.5}
]

Both customer references belong to the supplied list. All records are synthetic.

REVIEW
Synthetic data should satisfy declared relationships and remain clearly fictional. Include boundary cases when the goal is testing rather than demonstration.

This is a teaching example, not a live execution record.
