# Strict shuffled copy of `KantaHayashiAI/test`

This dataset was produced by assigning each source row a deterministic pseudo-random sort key
derived from:

- source parquet path
- row index inside that parquet
- shuffle seed `2026-04-01-strict-shuffle-v1`

Rows were first partitioned into `512` buckets by the high bits of the key,
then each bucket was fully sorted by `(__key_hi, __key_lo, __file_id, __row_idx)`.
This yields a deterministic global shuffled order without requiring the full dataset
to be materialized twice on local disk.

Expected train shard count: `512`.
