A thimble shop loses the photo but still has the care sentence and a tiny click. Late fusion could run the remaining specialists; early concat cannot invent pixels. What should guide the next step?
Select an answer to reveal the explanation.
Short Explanation
No photo means early concat has nothing to glue on that arm, while late specialists might still vote on what remains. Choose drop-or-keep based on how the example will actually be used.
