description: "Converts a supplied fee-token amount to the validator's token through Tempo's enshrined protocol Fee AMM (Tempo has no native gas token): validatorTokenOut = userTokenIn x 0.9970, 30bps to LPs. Checks the conversion against declared pool reserves for liquidity sufficiency and returns output-or-failure, never a silent overdraw. Fixed-point BigInt math at attodollar scale; calculator only, zero egress."
