## Licensing — traceable basis
Wikivoyage content is released under CC-BY-SA 3.0; attribution + share-alike preserved.

Fetched directly from the official Wikimedia dump (plwikivoyage-latest-pages-articles) by src/fetch_wikimedia.py; mainspace only, wikitext stripped via mwparserfromhell.

## Statistics
| documents | characters | tokens (tiktoken proxy) |
|---:|---:|---:|
| 13,645 | 45,184,300 | 17,128,200 |

## 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): **9**
- exact cross-source dedup (sha1): **1**
- OCR alpha-ratio < 0.70 (OCR sources only): **0**
- read 13,655 → kept 13,645

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