# Changelog

## v0.3.1-preview (2026-07-10)

- Added a separate 810-document Europeana direct-ingestion preview parquet at
  `previews/v0.3.1/europeana.parquet`. It was built from 1,000 live API records
  using per-record rights/creator metadata in 59.4 seconds; 808 retained records are Public
  Domain Mark and two are CC-BY-SA-4.0.
- The direct source gate dropped 181 non-Polish and nine OCR-garble records.
  `dsbench` found unique IDs, no empty text, no duplicate text and no eval-set
  overlap. Potential-phone matches remain warnings for manual review.
- This preview does not change v0.2.1 stable totals or promote Europeana to a
  stable source. It is the measured contract for the full rights-preserving run.

## v0.3.0-preview (in progress)

- Validated the source-policy gate on live local SpeakLeash shards: 12 reviewed
  sources sampled and cleared blocking checks; four sources remain excluded and
  two talk-page shards remain on hold pending a separate policy.
- Ran a direct Europeana 200-record rebuild probe with per-record rights and
  creator metadata: 197 Public Domain Mark and three CC-BY-SA-4.0 records
  cleared blocking validation. This is candidate validation, not a release
  inclusion.
- Biblioteka Nauki direct probe currently returns HTTP 500 and is held out of
  the preview until the upstream request is repaired and audited.

## v0.2.1 (2026-07-02)

- Released a stable metadata-schema update: `id, text, source, added, created, token_count, license, author`.
- Current release totals after parquet recount: 12 sources, 2,491,773 docs, 6.28B tokens (tiktoken proxy).
- Added `1000_novels` as a stable CC-BY-4.0 literature source.
- Added source registry entries and PR contract for future `biblioteka_nauki` and `europeana` ingestion with per-document license/author metadata. These sources are not included in v0.2.1 parquets yet.
- Credited Bart Kobyliński for source expansion work on Biblioteka Nauki and Europeana metadata/rebuild preparation.
- Kept raw SpeakLeash Europeana excluded unless a direct rebuild preserves per-record rights metadata.
- Sources: eurlex, parliamentary, wikisource, wikipedia, dziennik_ustaw, wolne_lektury, 1000_novels, wikiquote, eltec_pol, wikivoyage, wikibooks, wikinews.
- Excluded (see README): open_subtitles_corpus, europeana_eu_pl_corpus_raw_speakleash, project_gutenberg_pl_corpus.
