Could you build this?
Partial Writing a generic utility is straightforward, but parsing Apache Arrow binary specifications and correctly handling two's complement arbitrary-bitwidth decimal scaling requires exact low-level systems data handling.
What it would actually take: Implemented as a zero-dependency TypeScript/JavaScript package performing binary buffer manipulations. The hard part is correctly interpreting Apache Arrow's binary layout for 128-bit and 256-bit decimal values, handling signed two's complement integer math via native BigInt without precision loss, and applying correct scale factors across varying bitwidths.
