clm-backbone-5lang-sample
clm_prod 3B/7B BACKBONE corpus (step 2 DATA PREP). A bounded streaming SAMPLE — NOT the full 60B-token pretrain set (that is the step 3 H100 fire).

allenai/c4(mC4 multilingual), configsko/en/zh/ru/ja - License: ODC-BY (Open Data Commons Attribution)
- real_fraction: 1.0 — every line is real downloaded web text. NO synthesis, NO LLM generation.
- Preferred set blocked:
uonlp/CulturaXis GATED; the token has no data access (403 on stream) → fell back to c4. - Format: plain newline corpus, one text line per sample, byte-vocab V=256 (UTF-8). clm_prod reads it via
CLM_PROD_CORPUS. - Balance: 4000 docs/language, round-robin interleaved (5-way balanced).
