Case 51 — Case finishing: distinguish a reflection from a surface mark · source wording exercise

Reader check for “Case finishing: distinguish a reflection from a surface mark”: distinguish the discussion point “A mark should be assessed across multiple views; aggressive polishing…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.
