# TokLens Validation Data

2x10,000-line subsets sampled from FineWeb-Edu-10BT for validation:
one in-distribution split, one out-of-distribution split.

## Source
- In-distribution: fineweb_edu_10bt.chunk.00.jsonl
- Out-of-distribution: fineweb_edu_10bt.chunk.07.jsonl

## Sampling
Sampled with a fixed random source for reproducibility:

    shuf -n 10000 <input_file> --random-source=<(yes 42) > <output_file>

Note: reproducible given the same input file and shuf version, but not
a portable numeric seed (results may differ across machines/shuf versions).

## Files
- indistribution_chunk.00.jsonl (10,000 rows, from chunk.00)
- ood_chunk.07.jsonl (10,000 rows, from chunk.07)
