Case contract

For a nonempty list of nonnegative cell charge inventories and nonnegative request, return delivered charge and remaining cells; series cells each supply the delivered amount.

Why this case matters

An explicit synthetic battery bookkeeping model isolates this state-accounting error; it is not an engineering prediction or safety procedure.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
