Tracking Two Physical Cards with the Same Face
Two packs each contain a 7♥. Label the copies 7♥A and 7♥B when following their movements. The letters distinguish physical cards; they do not change the rank or make one seven stronger.

Follow the identifier across zones
Suppose 7♥A moves from a hand to the discard pile while 7♥B remains in the hand. A record that simply says “7♥ moved” cannot distinguish the two. Keeping the identifier stable makes the movement traceable without pretending that both copies changed location.
One card, one current location
After an accepted move, the same physical copy should not be counted in both the old and new zones of a settled inventory. Historical records may show both locations at different times. That is a timeline, not simultaneous ownership.
Use rank and suit when discussing face value; use the copy identifier when discussing a particular movement. The distinction is especially helpful when identical-looking cards appear in a replay. It resolves an identification problem without changing the game’s ranking rules.
A visible duplicate need not be an inventory duplicate
A replay may show 7♥A in its old position as part of an animation while the settled record places it in the discard pile. That is a display question. If the settled record itself assigns A to both areas, the inventory is inconsistent. Distinguishing a repeated picture from a repeated ownership entry makes the review more precise.
