未识别的主词条数值：{mainAffixValueLine}

Error message

未识别的主词条数值：{mainAffixValueLine}

What it means

Thrown when a main-affix value line was found (153 passed) but float.TryParse fails under NumberStyles.Any and the configured cultureInfo. The captured string is not a parseable number, so the main stat magnitude is unknown.

Solutions

1. Log mainAffixValueLine to see the exact unparseable string.
2. Align cultureInfo with the in-game locale's number format.
3. Pre-clean the string (strip non-numeric except the separator) before TryParse.
4. If the value is genuinely non-numeric for this artifact, handle it as a recognition failure per RecognitionFailurePolicy.

static string CleanNumber(string s, CultureInfo ci) =>
    Regex.Replace(s.Replace('。', '.'), ci.NumberFormat.NumberGroupSeparator, "");

When it happens

Trigger: The value line contains trailing/leading junk that slipped through the regex (e.g. a unit symbol, a stray letter); decimal separator mismatch with cultureInfo (e.g. '1.5' parsed under a comma-culture); OCR inserted a space inside the number; value is 'MAX' or non-numeric.

Common situations: cultureInfo set to a locale whose decimal separator differs from what OCR emitted; OCR noise characters; a leveled-to-cap artifact showing a non-numeric indicator.
