+publication years are recoverable from each item's source URL.

+upstream source above. SpeakLeash credited as intermediate aggregator; upstream license/attribution preserved.

+## Statistics
+| documents | characters | tokens (tiktoken proxy) |
+|---:|---:|---:|
+| 1,000 | 151,610,758 | 60,517,363 |
+
+## 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): **0**
+- exact cross-source dedup (sha1): **0**
+- OCR alpha-ratio < 0.70 (OCR sources only): **0**
+- read 1,000 → kept 1,000
+
+Token counts are a fast tiktoken (cl100k) proxy (~1% off Llama-3); the canonical
+Llama-3 count is computed at release.
