# Changelog

## v0.2.4 (2026-08-07)

- Expanded `european_hplt_v3_pl` (Arkadiusz Słota / `Maggio33`) from HPLT v3.0
  WDS quality bins 10+9 to **WDS bins 10-5**: +1,493,384 documents /
  2,043,141,874 cl100k-proxy tokens, 100% CC0-1.0. The source total is now
  1,603,974 documents / 2,555,525,652 tokens.
- Phone PII-scrub hardening (v12b): an independent-lens deep verification caught
  a systematic phone recall-gap (~1,900 real phone numbers) that the pipeline's
  self-report (idempotency) was structurally blind to — address-block
  suppression, `dzwoń`-label family, leading-0 landline, `+48`-paren,
  newline-over-span and foreign-UK-bare formats. Fixed and dual-independently
  verified; the residual 0.0135% is a classified clearance-tail. Phones map to a
  `[Telefon]` semantic tag (anti-poisoning, not a fake number).
- Cross-source deduplication of the expansion against the existing WDS-10+9
  shards: removed 3,038 near-duplicate documents (truncation variants);
  exact-dup 0, near-dup overlap 0.0000% (byte-verified). Resolves the
  "downstream near-dedup remains" caveat from the original release.
- Contract-revalidated the merged parquet (canonical schema, non-empty text,
  positive token counts, uniform source/license, stats-file consistency).
- Expanded contributor credit for Arkadiusz Słota (`Maggio33`) for the WDS 10-5
  expansion, PII-scrub and dedup work.
- Updated the complete-corpus release totals from per-source parquet stats:
  4,246,429 documents and 9,597,908,067 cl100k-proxy tokens (also reflects the
  separately-merged `biblioteka_nauki` source now present on main).

## v0.2.3 (2026-07-26)

- Added the community contribution `european_hplt_v3_pl` by Arkadiusz Słota
  (`Maggio33`): HPLT v3.0 Polish WDS quality bins 10+9, 110,590 documents and
  512,383,778 cl100k-proxy tokens under CC0-1.0 packaging.
- Added the reviewed `global_voices` contribution by Dawid Majewski
  (`dawidmajewski`): 2,040 documents / 3,715,020 tokens with CC-BY-3.0 and
  per-document author attribution metadata.
- Added `nkjp1m` from contributor `1am`: 18,381 documents / 2,601,201 tokens
  from the manually annotated 1-million-word NKJP subcorpus under the upstream
  version-unspecified CC-BY statement.
- Revalidated the contributed parquet against the canonical schema, non-empty
  text, positive token counts, uniform source/license metadata, and stats-file
  consistency.
- Updated the complete 16-source release totals from per-source parquet stats:
  2,710,974 documents and 6,881,277,362 cl100k-proxy tokens.
- Recomputed the full-corpus phrase-frequency report and charts. Updated the
  Arrow reporting path to use 64-bit string offsets for large row groups.
- Fixed `src/test_hplt_v3_contract.py` to resolve its fixture relative to the
  repository instead of a contributor-local Windows path.
- Added public contributor credit for Arkadiusz Słota (`Maggio33`) and Paweł
  Puzio (`ppuzio`, author of the `govpl` contribution released in v0.2.2), plus
  Dawid Majewski (`dawidmajewski`) for Global Voices Polish.
- HPLT caveat: CC0 applies to the HPLT packaging; underlying web documents can
  carry independent rights. Downstream near-dedup and web-content review remain
  recommended before training.

## v0.2.2 (2026-07-19)

- Added `govpl` — gov.pl Polish government press releases (CC-BY-SA-4.0),
  88,190 documents / 80.7M tokens, fetched directly from gov.pl across 133
  ministry/agency subsites. New scripts: `src/discover_govpl.py` (discovers each
  subsite's news-section path into the committed `src/govpl_subsites.json`
  manifest) and `src/fetch_govpl.py` (pure-stdlib crawl of that manifest).
- Stable totals after adding govpl: 13 sources, 2,579,963 docs, 6.36B tokens
  (tiktoken proxy).
- Article date range 2005-09-26 → 2026-07-19. Build dropped 24 non-Polish and
  deduped 1,926 cross-posted articles (exact sha1).

## 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.
