Dataset statistics

Per-subset stats over uploaded samples. Unique ctx counts distinct context strings, while the context-length buckets count samples/rows. Token counts use Qwen/Qwen3-14B.

Train pool: 1,724 unique contexts → 13,792 question rows (split into HF train + validation). OOD eval pool: 851 unique contexts → 851 question rows (uploaded as HF test; original LongBench input/answers with rubrics generated post-hoc).

Note on validation: for every in-domain subset the HF validation split contains a pooled copy of that subset's train rows in addition to the held-out validation rows. This grows the eval sample count for subsets with small validation holdouts (e.g. qmsum). The train split is unchanged. The stats above are de-duplicated, so they report each train row once.
