FA-12299 / Battery state accounting / Member archive
Capacity calibration invents stored charge · case 04
Capacity recalibration preserves a displayed fraction instead of stored inventory.
Case contract
Return absolute stored integer charge after replacing the capacity estimate; cap at new capacity. Old capacity is positive and charge lies within it.
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
