Case 5 — Crystal reflections: why a dark patch is not a coating test

Correction note for “Crystal reflections: why a dark patch is not a coating test”: retain the wording beginning “No single lighting setup settles…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
