Kimi-K2.7-CodingTraces-Sharded
Shuffled ~100 MB shards of trjxter/Kimi-K2.7-CodingTraces-9000x.
Source: trjxter/Kimi-K2.7-CodingTraces-9000x at revision 4adee21584f9e0f0b158eb662edb5374ce741fbb. Records are shuffled with seed 20260925 and split into ~100 MB parts; see MANIFEST.json for per-part hashes and record counts. Storage preparation only: no filtering or content change beyond the re-serialization noted above. Do not ingest until MANIFEST.json reports complete: true.
