Description
Premium=hammer*rate; tax base includes hammer and, only when taxPremium, its premium; total adds both charges.
Agribusiness records use explicit price bases, commissions, returns, minimum charges, credits and tax assumptions. A supplied arithmetic rule can reconcile a scenario while actual acceptance, contractual rights and legal liability require the governing agreement. Signed residual balances can be useful evidence of overpayment or inconsistent inputs.

}Limitations and assumptions
- No current tax law, tax-inclusive price convention, auction terms or entitlement is selected.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
