## Filters applied (build_dynaword.py)
Minimal, per Dynaword guidelines (heavy filtering left to downstream use):
- drop documents < 200 chars: **0**
- drop non-Polish (diacritic ratio): **1,390**
- exact cross-source dedup (sha1): **1,825**
- OCR alpha-ratio < 0.70 (OCR sources only): **0**
- read 246,275 → kept 243,060

Token counts are a fast tiktoken (cl100k) proxy (~1% off Llama-3); the canonical
Llama-3 count is computed at release.
