Side effects
- Missing required fields: if gross_profit or average_inventory_cost is absent from any row, the request will be rejected
- average_inventory_cost must be strictly greater than zero (exclusiveMinimum), a zero value will cause validation failure
- Fewer than 2 rows supplied: minimum row count is 2 for adjacent period comparison to be meaningful
- More than 200 rows: request exceeds maxItems limit and will be rejected
- Values outside the allowed numeric range (±1 trillion) will fail schema validation
