src/sources.py

"""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
# be rebuilt from direct upstream/export scripts rather than blind SpeakLeash pulls.
