未找到主词条数值对应的行： {mainAffixText}

Error message

未找到主词条数值对应的行：
{mainAffixText}

What it means

Thrown when the main-affix value line cannot be found: the LINQ Select over mainAffixLines matching the numeric pattern '^([\d., ]*)(%?)$' yields no single match. The artifact's main stat type was identified (152 passed) but its numeric value line is missing.

Solutions

1. Check allText / mainAffixText to see the captured value line format.
2. Confirm cultureInfo matches the in-game number formatting.
3. Widen mainAffixRoi if the value moved outside the crop.
4. Adjust the numeric regex to accept the locale's separators.

try { /* parse main affix value */ }
catch (Exception e) when (e.Message.Contains("主词条数值")) { if (policy == RecognitionFailurePolicy.Skip) continue; throw; }

When it happens

Trigger: OCR split the value across multiple lines or merged it with the type label; value contains characters the regex rejects (e.g. local decimal separator not in [\d., ]); the threshold step removed the value text; multiple lines matched causing SingleOrDefault to throw InvalidOperationException instead (distinct failure).

Common situations: Locale using a thousands separator outside the allowed set (e.g. space grouping already allowed, but apostrophe in some locales); UI scale change cropped the value out of mainAffixRoi; OCR mis-detection.
