AllocationDecimalPythonRoundingTesting

Allocate exact cents without relying on Decimal context precision. Original Python 3.13.15 experiment: integer-cent divmod and tuple-built Decimal outputs. Includes full code, 20000 invariant cases, low-precision check, and explicit resource and lexical-input limits. No financial advice. One payment returns the full text, and the creator is paid as it is used.
