## Unreleased (on main)

### v0.2.6-dev plan

Sources planned for v0.2.6: on main, but no release admits them yet (`release: None` in
`src/sources.py`). None has a recorded NERGAL pass, which is required before a
release can admit it. Together: 15 sources, 1,285,412 documents /
1,256,790,015 cl100k-proxy tokens.

- `uzp_orzeczenia_pl` by Piotr Styła: 34,715 documents / 422,043,881 tokens (Hub PR #39).
- `plwiki_user_talk` by Piotr Styła: 380,527 documents / 381,445,111 tokens (Hub PR #40).
- `sejm_committee_transcripts` by Piotr Styła: 653,411 documents / 166,310,754 tokens (Hub PR #37).
- `sejm_api_2011_2022` by Piotr Styła: 118,902 documents / 135,072,403 tokens (Hub PR #18).
- `plwiki_talk` by Piotr Styła: 43,054 documents / 55,568,733 tokens (Hub PR #36).
- `ted_pl` by Piotr Styła: 15,544 documents / 42,475,098 tokens (Hub PR #32).

- `nonsa` by Piotr Styła: 12,304 documents / 16,883,883 tokens (Hub PR #41).
- `open_icm_pl` by Piotr Styła: 85 documents / 2,358,174 tokens (Hub PR #34).
- `studia_bas` by gzawadzki (PR #19, landed by Piotr Styła): 112 documents / 2,256,009 tokens (Hub PR #44).
- `wiadomosci_statystyczne_pl` by Piotr Styła: 169 documents / 1,506,269 tokens (Hub PR #35).
- `rock_pollub_pl` by Piotr Styła: 8 documents / 1,177,858 tokens (Hub PR #33).
- `edukacja_medialna_pl` by Piotr Styła: 252 documents / 728,987 tokens (Hub PR #26).

Removed from main:

- `fandom_pl` (Piotr Styła, Hub PR #48; 50,653 documents / 45,790,009 tokens
  from 12 wikis, never released and never counted in the totals above) was
  removed on 2026-10-05. Fandom's Terms of Use (revision 2025-12-19) bar
  scraping, bypassing robot exclusion and AI training without written consent;
  the pages were fetched live from the wikis' APIs on 2026-10-02. Samples also
  showed game text, lyrics and translated third-party stories under the CC BY-SA
  label. The registry entry, builder, test and ontology manifest were removed
  with the data.
- `european_hplt_v3_pl` (1,603,974 documents / 2,555,525,652 tokens in
  v0.2.4 and v0.2.5) was removed by Arkadiusz Słota because its licence is
  unverified; it is re-added only after review. The registry keeps its
  `release: "0.2.3"` entry and `make_docs.py` skips it (no stats file). The
  v0.2.4 and v0.2.5 tags still contain it.
- `openstax_pl` (Piotr Styła, Hub PR #23; 1,422 documents / 4,632,374 tokens,
  never released) was removed on 2026-10-05. OpenStax Poland's live prefaces
  allow only non-commercial reuse and bar LLM training without its written
  consent, and its CMS lists the eight books as CC BY-NC-SA 4.0; the fetcher
  had hard-coded CC BY 4.0. The registry entry, fetcher, test and ontology
  manifest were removed with the data.
- `common_voice_pl` (Piotr Styła, Hub PR #22; 45,043 documents / 994,922
  tokens, never released) was removed on 2026-10-05. CC0 is Common Voice's
  platform-level label: 24,709 of the sentences come from Europarl, whose
  European Parliament reuse notice requires source acknowledgement, which CC0
  cannot carry, and the Sentence Collector sentences have no recorded sources.
  The registry entry, fetcher, contract test, ontology manifest and language
  audit were removed with the data.
- `wikiquote` (30,363 documents / 31,896,591 tokens in v0.2.0-v0.2.5) was
  removed on 2026-10-05. The October rights audit labelled 158 of 200 randomly
  sampled pages as quoting works still in copyright; CC BY-SA covers the
  contributors' selection, not the quotes, which rest on the Art. 29 quotation
  right. As with HPLT, the registry keeps its `release: "0.2.0"` entry (with a
  `legal_note`) and `make_docs.py` skips it; `plwikiquote` was dropped from
  `src/fetch_wikimedia.py`. The v0.2.0-v0.2.5 tags still contain it.
- `wikisource` (632,005 documents / 801,947,427 tokens in v0.2.0-v0.2.5) was
  removed on 2026-10-05. Every row carries one CC-BY-SA-3.0 label, but the
  October rights audit found in-copyright post-war imprints among 12 checked
  rows, each released by its rights holder under its own per-page licence (CC
  BY 3.0 PL, CC BY-SA 3.0 PL, CC BY-SA 3.0, GFDL, CC BY 4.0) and needing
  attribution the rows lack. The data came through SpeakLeash with an
  undocumented selection and no title, author or page id, so it cannot be
  screened. The registry keeps its `release: "0.2.0"` entry with a
  `legal_note`, and its `traceable` text no longer claims every text is public
  domain. A rebuild from the official dump with per-page licences is planned
  for a later release. The v0.2.0-v0.2.5 tags still contain it.

Changed on main:

- `samorzad_gov_pl` rebuilt from the de-identified upstream v0.2 (Dawid
  Majewski, Hub PR #15, landed as #46): 72,771 documents / 41,154,506 tokens
  in v0.2.5 → 72,472 / 40,011,099 on main.
- `1000_novels` keeps only its public-domain texts, relabelled
  `public-domain` (Hub PRs #49, #55): 1,000 documents / 60,517,363 tokens in
  v0.2.5 → 837 / 51,765,528 on main.
- `wiktionary_examples` dropped the lines quoting third-party works and is
  relabelled `CC-BY-SA-4.0` (Hub PR #50): 8,639 documents / 1,115,820 tokens
  in v0.2.5 → 1,818 / 207,181 on main.
- `nkjp1m` is relabelled `CC-BY-4.0` per the NKJP Consortium, with an agreed
  `ATTRIBUTION.md` (Hub PR #51); documents and text unchanged.
- The 17 v0.2.5 sources still on main total 2,093,026 documents /
  6,276,340,429 tokens; all 32 sources on main total 3,378,438 documents /
  7,533,130,444 tokens.

Tooling and process:

- PII scrubbing moved out of the repo to SlayerLab/NERGAL (#38); contextual
  PII masking improvements (#28).
- Releases are tagged (#31).
- Source PRs are separate from releases; `src/render_sample.py` renders PR data
  samples (#42).
- `build_dynaword.py` gained `preserve_id` / `preserve_created` flags (#45).
- The `v0.2.5` tag was re-pointed on 2026-09-29 from 02bcb0b to f71cc09, which
  corrects the v0.2.5 documentation to 20 sources. Every file under `data/` is
  byte-identical between the two commits.

## v0.2.5 (2026-08-14; tagged 2026-09-07)

- The v0.2.5 tag contains 20 sources: `samorzad_gov_pl`, `sejm_api` and
  `wiktionary_examples` were added in this release. `sejm_api` and
  `wiktionary_examples` were previously documented as built but not released
  (`release: None` in `src/sources.py`); that was a documentation error, and
  the registry now sets `release: "0.2.5"` for both.
- Added `sejm_api` by Piotr Styła: 38,812 parliamentary-speech documents
  (2023 onward) / 36,335,587 cl100k-proxy tokens from the official Sejm API,
  `public-domain (official documents)` (Hub PR #16).
- Added `wiktionary_examples` by Katarzyna Majzel-Pośpiech: 8,639 Polish
  Wiktionary usage-example documents / 1,115,820 cl100k-proxy tokens,
  `CC-BY-SA-3.0` (Hub PR #14).
- Added the community contribution `samorzad_gov_pl` by Dawid Majewski
  (`dawidmajewski`): 72,771 Polish articles / 41,154,506 cl100k-proxy tokens
  from 246 local public institutions and one central platform tenant using the
  shared samorzad.gov.pl platform.
- Converted the published, directly collected source dataset at revision
  `d5eaefc32c3f17cfa5a01d14573f8e4ee7d43385`; retained 72,771 of 81,422
  records after dropping 6,624 short, 35 below the Polish-language heuristic
  and 1,992 exact-duplicate records.
- Preserved the human-readable publishing institution in every `author` value.
  Added a 72,771-record attribution sidecar with discovered source URLs,
  fetched final URLs, recommended attribution URLs, titles, institution names,
  license URLs and modification notices.
- Added the frozen 247-institution publisher manifest, reproducible conversion
  script, contract tests, source datasheet, NOTICE and release-time license
  evidence. The live shared footer script matched the audited SHA-256
  `b36ec507901ed443195479d8d8009386159ae59d7486ce266bfb3308043e99aa`.
- Recomputed complete-corpus totals: 4,366,651 documents and 9,676,513,980
  cl100k-proxy tokens across 20 sources (earlier drafts of this entry gave
  4,319,200 documents / 9,639,062,573 tokens across 18 sources, before
  `sejm_api` and `wiktionary_examples` were counted).

## 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 across 17 sources
  (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.
