Example prompt: I have a list of 5 companies with their net income and average assets figures — can you rank all of them by return on average assets and tell me the formula used? The records are: Company A (net income 3000, avg assets 40000), Company B (net income 3300, avg assets 44000), Company C (net income 5000, avg assets 90000), Company D (net income 1200, avg assets 15000), Company E (net income 2800, avg assets 38000).

Choose this endpoint when you need to rank a batch of up to 200 financial records specifically by Return on Average Assets, with row indices preserved for traceability. It is purpose-built for ROAA ranking and returns the formula and limitations alongside results, making it auditable. Prefer it over generic sorting tools when you need a finance-domain-aware computation with clear provenance.

## Known failure modes

- Fewer than 2 records submitted — minimum of 2 rows required
- More than 200 records submitted — maximum array size exceeded
- average_assets value of zero or negative — excluded by schema (exclusiveMinimum:0)
- net_income or average_assets outside ±1,000,000,000,000 range — validation error
- Missing required fields net_income or average_assets on any row — schema validation failure
- Non-numeric values provided for financial figures — type error
