raw derive/fetch/pending: Länge als dritte Größenachse beim Ingest - eine CHECK-Zeile nennt jeden geschriebenen Text über LONG_TEXT_CHARS (Zeichen der .md wie geschrieben), raw pending markiert eine lange .md/.txt mit long:; ingest-large-tree liest ihn in Teilen nach der Gliederung, je Teil nur den Zeilenbereich, Extrakt als Faktenliste mit Fundstelle und Modalität (#226); 10.1.0-beta.10

+**A text too long for one pass is named.** After a success `raw derive` prints one more `CHECK`
+line naming every `.md` it wrote that is longer than one ingest reads in one pass. Length is
+counted in characters of the file as written, header included, not in tokens: characters are the

 **The original stays.** The derivation is the tool's reading of it, never the source: with the
 original kept, a claim in `kb/` can still be checked against what the document said when a
 derivation dropped something, and a later version of the tool can derive it better. Both go into
