name	custo-safra
description	Calculate and present crop cost estimates from repository-supported inputs with explicit units and assumptions. Use when changing cost composition rural-unit conversion or estimate output. Do not use when the task is climate ZARC or municipality lookup.

Custo safra

Inspect current cost models conversion helpers and supported units before editing.
Keep quantity unit unit-price and subtotal explicit for every component.
Preserve currency and reference-date metadata when available.
Separate user-provided values from repository reference values.
Reject incompatible units instead of silently converting them.
Make assumptions visible in the API or report output.
Add tests for totals conversions missing values and rounding boundaries.
Run Ruff and pytest from backend/.
