# Locus EXP Commit Code - Dolma 2 tokenized

Pretokenized experiment pool for reproducible proxy-training runs.

- `MANIFEST.json` is the authoritative schema, provenance, checksums, and train/holdout assignment.
- `shards/shard-NNNNN/tokens.bin` stores little-endian int32 token IDs.
- `offsets.bin` stores little-endian int64 document boundaries.
- `index.parquet` stores document IDs, offsets, and compact filter fields.
- `metadata.parquet` stores complete source metadata and is downloaded only for explicit cold-metadata filters.

Each document already ends in exactly one EOD token. Training must not add another document-level EOD.

Commit examples use `target_start_token` to mask the commit-message prompt and train only on the unified-diff target. Each commit document must fit one sequence.
