The before and after products match by exact arithmetic. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Before and after products match

Before: inertia 6 times spin 4 gives 24.

6×4=246\times4=24

Lower inertia pairs with higher spin

After: inertia 3 times spin 8 still gives 24.

The conservation verdict is a computed match

Because both sides are 24, the conservation ledger is accepted.
