Case 57 — Case finishing: distinguish a reflection from a surface mark · source wording exercise

A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?

Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A mark should be assessed across multiple views; aggressive polishing…” as the discussion anchor; no new event or result is supplied.

Exercise RWI-22111/57: address this question within its stated limits.
