"""Source registry for Polish DynaWord.



Each entry = one openly-licensed, *traceable* human-text source (paper 2508.02271,

principle: open+traceable licensing). The `traceable` field documents WHY the

license holds (not just "it's public domain") — e.g. statutory basis or upstream

license — as required by the Dynaword guidelines.



Provenance note: data is pulled from SpeakLeash's public redistribution

(iDrive e2 bucket) of these upstream sources; SpeakLeash is credited as the

intermediate aggregator, upstream license/attribution is preserved per source.

# clean-6: passed the copyright review (2026-06-15). open_subtitles excluded
# (derivative of copyrighted film dialogue — same lesson as Danish Gigaword).
# Large cultural/academic sources require per-record rights metadata and should
