Marco multilingual finetuning splits (c4)

Pre-built JSONL training splits for the Marco-MoE multilingual expansion experiments.

`splits/` — document-budget tiers (~15 GB)

Fixed-prefix document counts per language (50k ⊂ 100k ⊂ 500k):

Language	Source corpus
`dan_Latn`	FineWeb2-HQ
`fas_Arab`	FineWeb2-HQ
`swe_Latn`	FineWeb2-HQ
`tam_Taml`	FineWeb-2
`cat_Latn`	FineWeb-2

Files: {lang}_{50k|100k|500k}.jsonl, {lang}_manifest.json, splits_summary.json

Generated by finetuning/data/prepare_data_splits.py.

`token_budget_splits/` — token-budget tiers (~66 GB)

Fixed-seed shuffled splits at 1B / 1.5B / 2B raw tokenizer tokens:

Files: {lang}_{1Btok|1p5Btok|2Btok}.jsonl, {lang}_token_budget_manifest.json

Generated by finetuning/data/prepare_token_budget_splits.py (seed=42, Marco-Nano-Base tokenizer).
