USER MANUAL MRK-26 Mystery

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated text (underscores) where none should exist, violating the rule to ignore such lines. Hence, the OCR result is inconsistent with the Ground Truth.
