- StrataRow.nValue: text. "23" is a blow count (0–100), "50/5" a refusal
(50 blows for 5 mm, 1–300 mm). Empty means not known yet.
- G06 (warning): a malformed N value. Strict, because the values will feed the
bearing-capacity and liquefaction checks.
- The layer table has an N값 column; the project file checks that the rows
are well formed.
