Case contract

Given current identity and wear, incoming identity, and new discharge amount, return that slot wear: preserve for same identity, reset for different identity, then add discharge.

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
