-# Changelog
-
-## 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.

+# 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)

-### Version details
-
-#### v0.2.3 — current stable
-
-Community expansion release. Adds `european_hplt_v3_pl` from
-[PR #5](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/5)
-and `global_voices` from
-[PR #7](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/7),
-plus `nkjp1m` from
-[PR #8](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/8).
-The complete 16-source release contains **2,710,974 documents /
-6,881,277,362 cl100k-proxy tokens**, summed from the released per-source parquet
-statistics.
-
-#### v0.2.2 — previous stable
-
-Added `govpl` from
-[PR #9](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/9):
-88,190 Polish government press releases collected directly from 133 gov.pl
-ministry and agency subsites. Result: 13 sources, 2,579,963 documents and
-6.36B proxy tokens.
-
-#### v0.2.1 — previous stable
-
-Introduced the canonical eight-column release schema:
-`id, text, source, added, created, token_count, license, author`. Added the
-CC-BY-4.0 `1000_novels` source from
-[PR #1](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/1)
-and recomputed all release statistics from parquet files.
-
-#### v0.2.0 — initial stable corpus
-
-The provenance-first baseline: 11 reviewed open or official sources,
-2,490,773 documents and 6.22B proxy tokens. This version established the
-per-source datasheet, traceable-license and exclusion-policy workflow.
-
-#### v0.3-dev — experimental quality workflow
-
-Candidate-only work on a better-balanced training mixture: legal-source caps,
-temperature sampling, source QA, deduplication and direct-upstream ingestion.
-It is a workflow and validation track, not a replacement for the stable corpus.
-
-#### Europeana validation artifact — 2026-07-10
-
-A separate reproducible 810-document Europeana sample preserving per-record
-rights and creator metadata. It validates the direct-ingestion contract without
-changing stable-release totals. `v0.3.1-preview` remains only as the legacy
-storage-path label.
-
-## What this dataset contributes
-The raw texts come from existing open corpora (redistributed via SpeakLeash and,
-where applicable, fetched from upstream). **The value added here is the curation,
-not the bytes**, following the Dynaword methodology:
-
-1. **License review per source** — each source vetted for an *openly-licensed,
-   traceable* legal basis (documented in its datasheet); sources that fail the
-   review are **excluded with a stated reason** (see table below), not silently
-   kept. This is the core editorial work.
-2. **Filtering & normalization** — minimal, reproducible gates (short-doc,
-   non-Polish, exact cross-source dedup, OCR garble) applied uniformly to one
-   clean schema: `id, text, source, added, created, token_count, license, author`.
-3. **Documentation** — a datasheet per source (Gebru et al. 2021) + this card,
-   so provenance and licensing are auditable rather than assumed.
-4. **Reproducibility & versioning** — `src/` rebuilds the corpus from sources;
-   new sources and removals are tracked in the CHANGELOG.
-
-Credit for the underlying texts belongs to the upstream sources and to SpeakLeash
-as the redistributing aggregator; this release does not claim ownership of them
-(see Disclaimer).

-
-## Guiding principles
-1. **Open & traceable licensing** — every source is *openly licensed* with a documented
-   legal basis (see each datasheet's "traceable basis"), not a vague "public domain".
-2. **Reproducibility** — `src/build_dynaword.py` rebuilds the corpus from sources.
-3. **Documented** — a datasheet per source under `data/<source>/`.
-4. **Extensibility** — versioned; new sources via PR.

-## Method
-Only **human-authored** text — no synthetic, machine-translated, or auto-transcribed
-data. Gates are intentionally minimal (drop short docs, non-Polish, exact duplicates,
-OCR garble); heavy quality filtering and mix-weighting are left to downstream training.
-Evaluation-set decontamination is applied/marked separately. Schema:
-`id, text, source, added, created, token_count, license, author`. The `license`
-and `author` columns are per-document metadata when upstream exposes them; older
-sources use the source-level license and an empty author field.
-
-## v0.3 quality roadmap and current status
-
-The v0.2.x raw corpus is intentionally provenance-first, but its token mix is too
-heavy in legal/parliamentary language for natural general pretraining. The v0.3
-workflow therefore separates **source inclusion** from **training mix**:
-
-- cap `eurlex + parliamentary + dziennik_ustaw` to roughly **10-20%** of training
-  tokens combined;
-- use source-level temperature sampling (`sqrt`, alpha `0.5`) instead of raw
-  token-proportional sampling;
-- add traceably licensed contemporary/natural Polish: open web, academic prose,
-  cultural heritage text, guides, technical documentation/blogs, Q&A, and
-  dialogue/instruction data;
-- run aggressive exact, normalized, and near-duplicate removal;
-- reserve the final **5-15%** of training for higher-quality sources rather than
-  the largest sources;
-- evaluate per-source perplexity and style contamination, not only global loss.
-
-Current v0.3 source-ingestion status:
-
-- `biblioteka_nauki`: prepared in the source registry as a direct-upstream
-  rebuild target with per-document license and author metadata. A live probe
-  currently returns HTTP 500 and zero records, so it is **not included** in
-  v0.2.1 or the v0.3 preview candidate data.
-- `europeana`: prepared in the source registry as a direct-upstream rebuild
-  target with per-record rights statements and creator metadata. A 200-record
-  live direct-rebuild audit found 197 Public Domain Mark records and three
-  CC-BY-SA-4.0 records; all passed the blocking schema, license, duplicate and
-  evaluation-overlap gates. It remains candidate-only until a complete rebuild,
-  date split, and legal review are complete. Raw SpeakLeash Europeana remains
-  excluded.
-- Local SpeakLeash shard audit: 12 reviewed source shards were sampled directly
-  from the live `.jsonl.zst` inputs and passed the blocking gates; four shards
-  are explicitly excluded (`open_subtitles_corpus`, raw Europeana,
-  `1000_novels_corpus_CLARIN-PL`, `project_gutenberg_pl_corpus`) and two talk
-  shards remain on hold pending a separate source policy. The audit mechanism is
-  aligned with [slayer-dsbench](https://github.com/slayerlabs/slayer-dsbench).
-- Europeana release policy: split conservatively at pre-1929 records for
-  US-sensitive downstream reuse, and keep later/unknown records separately
-  labeled or held until legal review.
-- `european_hplt_v3_pl`: WDS bins 10+9 are included in v0.2.3 after contract
-  validation. HPLT packaging is CC0, while underlying crawled web documents can
-  carry independent rights; downstream near-dedup and web-content review remain
-  recommended before training.
-
-Current review artifacts:
-
-- `configs/source_candidates_v0_3.json` — candidate decisions and license policy.
-- `artifacts/source_license_review_v0_3.md` — source-by-source license review.
-- `artifacts/source_candidate_audit_v0_3.md` — generated Hugging Face metadata audit.
-- `artifacts/training_mix_v0_3.md` — example 1B-token training mix with legal sources capped at 15%.
-- `artifacts/bartek_source_ingestion_plan_2026-07-02.md` — PR contract for
-  Biblioteka Nauki and Europeana ingestion.

-## Excluded sources (transparency)
-Sources we reviewed and **deliberately left out** — part of the curation:
-
-| source | reason |
-|---|---|
-| `open_subtitles_corpus` | Derivative of copyrighted film/TV dialogue; OpenSubtitles uploads largely unlicensed. Same copyright lesson as Danish Gigaword's OpenSubtitles (paper 2508.02271). Not openly licensed. |
-| `europeana_eu_pl_corpus_raw_speakleash` | Aggregated items with mixed per-record rights (PD / CC-BY-NC / rights-reserved). The raw SpeakLeash redistribution is excluded; only a direct rebuild preserving per-record rights metadata may be included. |
-| `project_gutenberg_pl_corpus` | Only 31 PL books (4.3MB) — PG is ~99% English; Polish PD literature already covered by wolne_lektury + wikisource (so near-redundant after dedup). Dropped to avoid the PD-in-EU per-work check (PG claims PD-in-US only) for negligible token gain. |
-
-## Personal & sensitive data
-This corpus contains **only** text that its upstream sources already published
-under open licenses or as official public-domain record. It therefore includes
-names and statements of **public figures acting in a public capacity** — e.g.
-parliamentary speakers (PPC), authorities named in legal acts (EUR-Lex), and
-people described in encyclopedic articles (Wikipedia/Wikisource). No private,
-non-public personal data was collected or added. If you are a data subject and
-want content concerning you removed, contact **k.wikiel@gmail.com** — it will be dropped
-from the next version (see retroactive-removal policy below).
-
-## Disclaimer & legal
-- **Provenance in good faith.** Per-source licenses are reproduced *as documented
-  by the upstream sources and by SpeakLeash* (the intermediate aggregator), to the
-  best of our knowledge. We make no independent legal warranty about the copyright
-  status of any individual document.
-- **No ownership claim.** This release is a *curated, license-reviewed, documented
-  aggregation*. We claim no ownership of the underlying texts; rights remain with
-  the original authors/rightsholders under their respective licenses.
-- **Provided "as is"**, without warranty of any kind, express or implied. This is
-  not legal advice.
-- **Your compliance is yours.** Downstream users must satisfy each upstream
-  license themselves — in particular **CC-BY-SA-4.0 attribution and share-alike**
-  for derivatives of this dataset, and attribution to the upstream sources and to
-  SpeakLeash.
-- **Notice-and-takedown.** Any source or rightsholder raising a substantiated
-  objection can have material removed: contact **k.wikiel@gmail.com**; it is dropped from
-  the next version and recorded in the CHANGELOG. Removal is retroactive
-  going-forward (prior immutable snapshots/commits may persist).
-
-## License & attribution
-Released under **CC-BY-SA-4.0** (copyleft inherited from CC-BY-SA sources such as
-Wikipedia/Wikisource/Wolne Lektury). Attribution due to each upstream (see datasheets)
-and to **SpeakLeash** as the intermediate aggregator. Retroactive-removal policy: a
-source that raises an objection is dropped from subsequent versions, recorded in the
-CHANGELOG.

+
+| version | status | documents | tokens | notes |
+|---|---|---:|---:|---|
+| `v0.2.4` | stable release | 4,246,429 | 9.60B | Expanded `european_hplt_v3_pl` to WDS bins 10-5 (+1.49M docs / 2.04B tok); phone PII-scrub hardening (independent dual-lens) + cross-source dedup (zero-overlap). |

+### Development and validation artifacts
+
+| name | type | scope | notes |
+|---|---|---|---|
+| `v0.3-dev` | experimental development track | workflow and candidate audits | Quality remix, legal-source caps, source QA, deduplication and direct-upstream ingestion. Not a corpus release. |
+| `Europeana validation artifact 2026-07-10` | reproducible sample | 810 documents / 140,042 tokens | Stored at the legacy path `previews/v0.3.1/europeana.parquet`; preserves per-record rights and creator metadata. Not a corpus release. |
+
+### Version details
+
+#### v0.2.4 — current stable
+
+Expanded `european_hplt_v3_pl` from WDS bins 10+9 to **WDS bins 10-5** (added
+quality bins 8/7/6/5 and further WDS-9 shards): **+1,493,384 documents /
+2,043,141,874 cl100k-proxy tokens**, 100% CC0-1.0. Includes a phone PII-scrub
+hardening pass (v12b) verified by two independent lenses (a systematic
+recall-gap masked by pipeline self-report was caught pre-release), and
+cross-source deduplication against the existing WDS-10+9 shards (exact-dup 0,
+near-dup overlap 0.0000%, byte-verified) — resolving the "downstream near-dedup
+remains" caveat from the original release.
+
+#### v0.2.3 — previous stable
+
+Community expansion release. Adds `european_hplt_v3_pl` from
+[PR #5](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/5)
+and `global_voices` from
+[PR #7](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/7),
+plus `nkjp1m` from
+[PR #8](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/8).
+The complete 16-source release contains **2,710,974 documents /
+6,881,277,362 cl100k-proxy tokens**, summed from the released per-source parquet
+statistics.
+
+#### v0.2.2 — previous stable
+
+Added `govpl` from
+[PR #9](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/9):
+88,190 Polish government press releases collected directly from 133 gov.pl
+ministry and agency subsites.
+
+#### v0.2.1 — previous stable
+
+Introduced the canonical eight-column release schema:
+`id, text, source, added, created, token_count, license, author`. Added
+`1000_novels` from
+[PR #1](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/1)
+and recomputed all release statistics from parquet files.
+
+#### v0.2.0 — initial stable corpus
+
+The provenance-first baseline: 11 reviewed open or official sources,
+2,490,773 documents and 6.22B proxy tokens.
+
+#### v0.3-dev — experimental quality workflow
+
+Candidate-only work on a better-balanced training mixture: legal-source caps,
+temperature sampling, source QA, deduplication and direct-upstream ingestion.
+It is not a replacement for the stable corpus.
+
+#### Europeana validation artifact — 2026-07-10
+
+A separate reproducible 810-document Europeana sample preserving per-record
+rights and creator metadata. It does not change stable-release totals.
+`v0.3.1-preview` remains only as the legacy storage-path label.
+
+## What this dataset contributes
+The raw texts come from existing open corpora (redistributed via SpeakLeash and,
+where applicable, fetched from upstream). **The value added here is the curation,
+not the bytes**, following the Dynaword methodology:
+
+1. **License review per source** — each source vetted for an *openly-licensed,
+   traceable* legal basis (documented in its datasheet); sources that fail the
+   review are **excluded with a stated reason** (see table below), not silently
+   kept. This is the core editorial work.
+2. **Filtering & normalization** — minimal, reproducible gates (short-doc,
+   non-Polish, exact cross-source dedup, OCR garble) applied uniformly to one
+   clean schema: `id, text, source, added, created, token_count, license, author`.
+3. **Documentation** — a datasheet per source (Gebru et al. 2021) + this card,
+   so provenance and licensing are auditable rather than assumed.
+4. **Reproducibility & versioning** — `src/` rebuilds the corpus from sources;
+   new sources and removals are tracked in the CHANGELOG.
+
+Credit for the underlying texts belongs to the upstream sources and to SpeakLeash
+as the redistributing aggregator; this release does not claim ownership of them
+(see Disclaimer).

+
+## Guiding principles
+1. **Open & traceable licensing** — every source is *openly licensed* with a documented
+   legal basis (see each datasheet's "traceable basis"), not a vague "public domain".
+2. **Reproducibility** — `src/build_dynaword.py` rebuilds the corpus from sources.
+3. **Documented** — a datasheet per source under `data/<source>/`.
+4. **Extensibility** — versioned; new sources via PR.

+
+## Method
+Only **human-authored** text — no synthetic, machine-translated, or auto-transcribed
+data. Gates are intentionally minimal (drop short docs, non-Polish, exact duplicates,
+OCR garble); heavy quality filtering and mix-weighting are left to downstream training.
+Evaluation-set decontamination is applied/marked separately. Schema:
+`id, text, source, added, created, token_count, license, author`. The `license`
+and `author` columns are per-document metadata when upstream exposes them; older
+sources use the source-level license and an empty author field.
+
+## v0.3 quality roadmap and current status
+
+The v0.2.x raw corpus is intentionally provenance-first, but its token mix is too
+heavy in legal/parliamentary language for natural general pretraining. The v0.3
+workflow therefore separates **source inclusion** from **training mix**:
+
+- cap `eurlex + parliamentary + dziennik_ustaw` to roughly **10-20%** of training
+  tokens combined;
+- use source-level temperature sampling (`sqrt`, alpha `0.5`) instead of raw
+  token-proportional sampling;
+- add traceably licensed contemporary/natural Polish: open web, academic prose,
+  cultural heritage text, guides, technical documentation/blogs, Q&A, and
+  dialogue/instruction data;
+- run aggressive exact, normalized, and near-duplicate removal;
+- reserve the final **5-15%** of training for higher-quality sources rather than
+  the largest sources;
+- evaluate per-source perplexity and style contamination, not only global loss.
+
+Current v0.3 source-ingestion status:
+
+- `biblioteka_nauki`: prepared in the source registry as a direct-upstream
+  rebuild target with per-document license and author metadata; not included in
+  v0.2.4 parquets yet.
+- `europeana`: prepared in the source registry as a direct-upstream rebuild
+  target with per-record rights statements and creator metadata; raw SpeakLeash
+  Europeana remains excluded.
+- Europeana release policy: split conservatively at pre-1929 records for
+  US-sensitive downstream reuse, and keep later/unknown records separately
+  labeled or held until legal review.
+- `european_hplt_v3_pl`: WDS bins 10+9 are included in v0.2.4 after contract
+  validation. HPLT packaging is CC0, while underlying crawled web documents can
+  carry independent rights; downstream near-dedup and web-content review remain
+  recommended before training.
+
+Current review artifacts:
+
+- `configs/source_candidates_v0_3.json` — candidate decisions and license policy.
+- `artifacts/source_license_review_v0_3.md` — source-by-source license review.
+- `artifacts/source_candidate_audit_v0_3.md` — generated Hugging Face metadata audit.
+- `artifacts/training_mix_v0_3.md` — example 1B-token training mix with legal sources capped at 15%.
+- `artifacts/bartek_source_ingestion_plan_2026-07-02.md` — PR contract for
+  Biblioteka Nauki and Europeana ingestion.
+
+## Excluded sources (transparency)
+Sources we reviewed and **deliberately left out** — part of the curation:
+
+| source | reason |
+|---|---|
+| `open_subtitles_corpus` | Derivative of copyrighted film/TV dialogue; OpenSubtitles uploads largely unlicensed. Same copyright lesson as Danish Gigaword's OpenSubtitles (paper 2508.02271). Not openly licensed. |
+| `europeana_eu_pl_corpus_raw_speakleash` | Aggregated items with mixed per-record rights (PD / CC-BY-NC / rights-reserved). The raw SpeakLeash redistribution is excluded; only a direct rebuild preserving per-record rights metadata may be included. |
+| `1000_novels_corpus_CLARIN-PL` | CC-BY-4.0 label, but 'novels' likely include in-copyright contemporary works; verify titles/years on CLARIN handle 11321/312 before inclusion. |
+| `project_gutenberg_pl_corpus` | Only 31 PL books (4.3MB) — PG is ~99% English; Polish PD literature already covered by wolne_lektury + wikisource (so near-redundant after dedup). Dropped to avoid the PD-in-EU per-work check (PG claims PD-in-US only) for negligible token gain. |
+
+## Personal & sensitive data
+This corpus contains **only** text that its upstream sources already published
+under open licenses or as official public-domain record. It therefore includes
+names and statements of **public figures acting in a public capacity** — e.g.
+parliamentary speakers (PPC), authorities named in legal acts (EUR-Lex), and
+people described in encyclopedic articles (Wikipedia/Wikisource). No private,
+non-public personal data was collected or added. If you are a data subject and
+want content concerning you removed, contact **k.wikiel@gmail.com** — it will be dropped
+from the next version (see retroactive-removal policy below).
+
+## Disclaimer & legal
+- **Provenance in good faith.** Per-source licenses are reproduced *as documented
+  by the upstream sources and by SpeakLeash* (the intermediate aggregator), to the
+  best of our knowledge. We make no independent legal warranty about the copyright
+  status of any individual document.
+- **No ownership claim.** This release is a *curated, license-reviewed, documented
+  aggregation*. We claim no ownership of the underlying texts; rights remain with
+  the original authors/rightsholders under their respective licenses.
+- **Provided "as is"**, without warranty of any kind, express or implied. This is
+  not legal advice.
+- **Your compliance is yours.** Downstream users must satisfy each upstream
+  license themselves — in particular **CC-BY-SA-4.0 attribution and share-alike**
+  for derivatives of this dataset, and attribution to the upstream sources and to
+  SpeakLeash.
+- **Notice-and-takedown.** Any source or rightsholder raising a substantiated
+  objection can have material removed: contact **k.wikiel@gmail.com**; it is dropped from
+  the next version and recorded in the CHANGELOG. Removal is retroactive
+  going-forward (prior immutable snapshots/commits may persist).
+
+## License & attribution
+Released under **CC-BY-SA-4.0** (copyleft inherited from CC-BY-SA sources such as
+Wikipedia/Wikisource/Wolne Lektury). Attribution due to each upstream (see datasheets)
+and to **SpeakLeash** as the intermediate aggregator. Retroactive-removal policy: a
+source that raises an objection is dropped from subsequent versions, recorded in the
+CHANGELOG.

+## PII phone-scrub (v12b) & cross-source dedup
+- **Phones → `[Telefon]`** (semantic-tag, not fake-number — avoids model-poisoning). Iterative scrub v6→v12b closed all systematic phone-recall classes (address-block-suppression, `dzwoń`-label family, leading-0 landline, `+48`-paren, newline-over-span, foreign-UK-bare). Residual **0.0135%** = genuine clearance-tail (FP-not-phone / foreign-out-of-scope / bare-no-leading-0-ambiguous / label-distance / institutional-published / rare-edge). Email/national-ID → `[PII]`.
+- **Verification:** TWO independent lenses (deep-verify + broad recall-scan), NOT pipeline self-report — a self-report (idempotency) blind-spot had masked a systematic recall-gap; the independent gate caught it pre-release (SAFETY-INVARIANT: check-coverage ≥ scrub-coverage).
+- **Cross-source dedup vs the existing WDS-10+9 file:** expansion deduplicated against the base shards — **exact-dup = 0, near-dup overlap = 0.0000% (byte-verified)**. This resolves the "cross-source near/containment dedup remains a downstream step" caveat from the original release.
 
 ## Status & caveats (web-crawl - NOT "release-clean")
-- **Copyright is not fully solved by filtering.** The length cap removes obvious book-length works, but
-  in-copyright text recurs in web-crawl at ALL lengths (news reprints, blog reposts, excerpts). Inherent to
-  web sources; the reason HPLT ships CC0-on-packaging + notice-and-takedown.
-- **Near-dup NOT removed** (Dynaword leaves heavy filtering downstream). ~11.8% of an HPLT sample's 8-grams
-  overlap Polish Wikipedia; wikipedia/wikisource domain exclusion mitigates the largest sources, but
-  cross-source near/containment dedup vs the full corpus remains a downstream step.
-- Surface-metric parity with accepted sources: mojibake 0%, boilerplate ~0.2%, diacritic-ratio ~0.066,
-  TTR@500 ~0.64 (within the accepted range, ~= parliamentary). ~9% commercial/SEO-adjacent pages (web-inherent).
-- This is 2 top bins merged. The full `pol_Latn` corpus is ~270B raw tokens across WDS bins 10->5.

-### Version details
-
-#### v0.2.3 — current stable
-
-Community expansion release. Adds `european_hplt_v3_pl` from
-[PR #5](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/5)
-and `global_voices` from
-[PR #7](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/7),
-plus `nkjp1m` from
-[PR #8](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/8).
-The complete 16-source release contains **2,710,974 documents /
-6,881,277,362 cl100k-proxy tokens**, summed from the released per-source parquet
-statistics.
-
-#### v0.2.2 — previous stable
-
-Added `govpl` from
-[PR #9](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/9):
-88,190 Polish government press releases collected directly from 133 gov.pl
-ministry and agency subsites.
-
-#### v0.2.1 — previous stable
-
-Introduced the canonical eight-column release schema:
-`id, text, source, added, created, token_count, license, author`. Added
-`1000_novels` from
-[PR #1](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/1)
-and recomputed all release statistics from parquet files.
-
-#### v0.2.0 — initial stable corpus
-
-The provenance-first baseline: 11 reviewed open or official sources,
-2,490,773 documents and 6.22B proxy tokens.
-
-#### v0.3-dev — experimental quality workflow
-
-Candidate-only work on a better-balanced training mixture: legal-source caps,
-temperature sampling, source QA, deduplication and direct-upstream ingestion.
-It is not a replacement for the stable corpus.
-
-#### Europeana validation artifact — 2026-07-10
-
-A separate reproducible 810-document Europeana sample preserving per-record
-rights and creator metadata. It does not change stable-release totals.
-`v0.3.1-preview` remains only as the legacy storage-path label.
-
-## What this dataset contributes
-The raw texts come from existing open corpora (redistributed via SpeakLeash and,
-where applicable, fetched from upstream). **The value added here is the curation,
-not the bytes**, following the Dynaword methodology:
-
-1. **License review per source** — each source vetted for an *openly-licensed,
-   traceable* legal basis (documented in its datasheet); sources that fail the
-   review are **excluded with a stated reason** (see table below), not silently
-   kept. This is the core editorial work.
-2. **Filtering & normalization** — minimal, reproducible gates (short-doc,
-   non-Polish, exact cross-source dedup, OCR garble) applied uniformly to one
-   clean schema: `id, text, source, added, created, token_count, license, author`.
-3. **Documentation** — a datasheet per source (Gebru et al. 2021) + this card,
-   so provenance and licensing are auditable rather than assumed.
-4. **Reproducibility & versioning** — `src/` rebuilds the corpus from sources;
-   new sources and removals are tracked in the CHANGELOG.
-
-Credit for the underlying texts belongs to the upstream sources and to SpeakLeash
-as the redistributing aggregator; this release does not claim ownership of them
-(see Disclaimer).

-
-## Guiding principles
-1. **Open & traceable licensing** — every source is *openly licensed* with a documented
-   legal basis (see each datasheet's "traceable basis"), not a vague "public domain".
-2. **Reproducibility** — `src/build_dynaword.py` rebuilds the corpus from sources.
-3. **Documented** — a datasheet per source under `data/<source>/`.
-4. **Extensibility** — versioned; new sources via PR.
-
-## Sources
-| source | description | license | documents | tokens |
-|---|---|---|---:|---:|
-{tbl}
-| **total** | | | **{tot_doc:,}** | **{tot_tok/1e6:,.1f}M** |
-
-## Method
-Only **human-authored** text — no synthetic, machine-translated, or auto-transcribed
-data. Gates are intentionally minimal (drop short docs, non-Polish, exact duplicates,
-OCR garble); heavy quality filtering and mix-weighting are left to downstream training.
-Evaluation-set decontamination is applied/marked separately. Schema:
-`id, text, source, added, created, token_count, license, author`. The `license`
-and `author` columns are per-document metadata when upstream exposes them; older
-sources use the source-level license and an empty author field.
-
-## v0.3 quality roadmap and current status
-
-The v0.2.x raw corpus is intentionally provenance-first, but its token mix is too
-heavy in legal/parliamentary language for natural general pretraining. The v0.3
-workflow therefore separates **source inclusion** from **training mix**:
-
-- cap `eurlex + parliamentary + dziennik_ustaw` to roughly **10-20%** of training
-  tokens combined;
-- use source-level temperature sampling (`sqrt`, alpha `0.5`) instead of raw
-  token-proportional sampling;
-- add traceably licensed contemporary/natural Polish: open web, academic prose,
-  cultural heritage text, guides, technical documentation/blogs, Q&A, and
-  dialogue/instruction data;
-- run aggressive exact, normalized, and near-duplicate removal;
-- reserve the final **5-15%** of training for higher-quality sources rather than
-  the largest sources;
-- evaluate per-source perplexity and style contamination, not only global loss.
-
-Current v0.3 source-ingestion status:
-
-- `biblioteka_nauki`: prepared in the source registry as a direct-upstream
-  rebuild target with per-document license and author metadata; not included in
-  v{VERSION} parquets yet.
-- `europeana`: prepared in the source registry as a direct-upstream rebuild
-  target with per-record rights statements and creator metadata; raw SpeakLeash
-  Europeana remains excluded.
-- Europeana release policy: split conservatively at pre-1929 records for
-  US-sensitive downstream reuse, and keep later/unknown records separately
-  labeled or held until legal review.
-- `european_hplt_v3_pl`: WDS bins 10+9 are included in v{VERSION} after contract
-  validation. HPLT packaging is CC0, while underlying crawled web documents can
-  carry independent rights; downstream near-dedup and web-content review remain
-  recommended before training.
-
-Current review artifacts:
-
-- `configs/source_candidates_v0_3.json` — candidate decisions and license policy.
-- `artifacts/source_license_review_v0_3.md` — source-by-source license review.
-- `artifacts/source_candidate_audit_v0_3.md` — generated Hugging Face metadata audit.
-- `artifacts/training_mix_v0_3.md` — example 1B-token training mix with legal sources capped at 15%.
-- `artifacts/bartek_source_ingestion_plan_2026-07-02.md` — PR contract for
-  Biblioteka Nauki and Europeana ingestion.

+
+### Version details
+
+#### v0.2.4 — current stable
+
+Expanded `european_hplt_v3_pl` from WDS bins 10+9 to **WDS bins 10-5** (added
+quality bins 8/7/6/5 and further WDS-9 shards): **+1,493,384 documents /
+2,043,141,874 cl100k-proxy tokens**, 100% CC0-1.0. Includes a phone PII-scrub
+hardening pass (v12b) verified by two independent lenses (a systematic
+recall-gap masked by pipeline self-report was caught pre-release), and
+cross-source deduplication against the existing WDS-10+9 shards (exact-dup 0,
+near-dup overlap 0.0000%, byte-verified) — resolving the "downstream near-dedup
+remains" caveat from the original release.
+
+#### v0.2.3 — previous stable
+
+Community expansion release. Adds `european_hplt_v3_pl` from
+[PR #5](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/5)
+and `global_voices` from
+[PR #7](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/7),
+plus `nkjp1m` from
+[PR #8](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/8).
+The complete 16-source release contains **2,710,974 documents /
+6,881,277,362 cl100k-proxy tokens**, summed from the released per-source parquet
+statistics.
+
+#### v0.2.2 — previous stable
+
+Added `govpl` from
+[PR #9](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/9):
+88,190 Polish government press releases collected directly from 133 gov.pl
+ministry and agency subsites.
+
+#### v0.2.1 — previous stable
+
+Introduced the canonical eight-column release schema:
+`id, text, source, added, created, token_count, license, author`. Added
+`1000_novels` from
+[PR #1](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/1)
+and recomputed all release statistics from parquet files.
+
+#### v0.2.0 — initial stable corpus
+
+The provenance-first baseline: 11 reviewed open or official sources,
+2,490,773 documents and 6.22B proxy tokens.
+
+#### v0.3-dev — experimental quality workflow
+
+Candidate-only work on a better-balanced training mixture: legal-source caps,
+temperature sampling, source QA, deduplication and direct-upstream ingestion.
+It is not a replacement for the stable corpus.
+
+#### Europeana validation artifact — 2026-07-10
+
+A separate reproducible 810-document Europeana sample preserving per-record
+rights and creator metadata. It does not change stable-release totals.
+`v0.3.1-preview` remains only as the legacy storage-path label.

+The raw texts come from existing open corpora (redistributed via SpeakLeash and,
+where applicable, fetched from upstream). **The value added here is the curation,
+not the bytes**, following the Dynaword methodology:
+
+1. **License review per source** — each source vetted for an *openly-licensed,
+   traceable* legal basis (documented in its datasheet); sources that fail the
+   review are **excluded with a stated reason** (see table below), not silently
+   kept. This is the core editorial work.
+2. **Filtering & normalization** — minimal, reproducible gates (short-doc,
+   non-Polish, exact cross-source dedup, OCR garble) applied uniformly to one
+   clean schema: `id, text, source, added, created, token_count, license, author`.
+3. **Documentation** — a datasheet per source (Gebru et al. 2021) + this card,
+   so provenance and licensing are auditable rather than assumed.
+4. **Reproducibility & versioning** — `src/` rebuilds the corpus from sources;
+   new sources and removals are tracked in the CHANGELOG.
+
+Credit for the underlying texts belongs to the upstream sources and to SpeakLeash
+as the redistributing aggregator; this release does not claim ownership of them
+(see Disclaimer).

+
+## Guiding principles
+1. **Open & traceable licensing** — every source is *openly licensed* with a documented
+   legal basis (see each datasheet's "traceable basis"), not a vague "public domain".
+2. **Reproducibility** — `src/build_dynaword.py` rebuilds the corpus from sources.
+3. **Documented** — a datasheet per source under `data/<source>/`.
+4. **Extensibility** — versioned; new sources via PR.
+
+## Sources
+| source | description | license | documents | tokens |
+|---|---|---|---:|---:|
+{tbl}
+| **total** | | | **{tot_doc:,}** | **{tot_tok/1e6:,.1f}M** |
+
+## Method
+Only **human-authored** text — no synthetic, machine-translated, or auto-transcribed
+data. Gates are intentionally minimal (drop short docs, non-Polish, exact duplicates,
+OCR garble); heavy quality filtering and mix-weighting are left to downstream training.
+Evaluation-set decontamination is applied/marked separately. Schema:
+`id, text, source, added, created, token_count, license, author`. The `license`
+and `author` columns are per-document metadata when upstream exposes them; older
+sources use the source-level license and an empty author field.
+
+## v0.3 quality roadmap and current status
+
+The v0.2.x raw corpus is intentionally provenance-first, but its token mix is too
+heavy in legal/parliamentary language for natural general pretraining. The v0.3
+workflow therefore separates **source inclusion** from **training mix**:
+
+- cap `eurlex + parliamentary + dziennik_ustaw` to roughly **10-20%** of training
+  tokens combined;
+- use source-level temperature sampling (`sqrt`, alpha `0.5`) instead of raw
+  token-proportional sampling;
+- add traceably licensed contemporary/natural Polish: open web, academic prose,
+  cultural heritage text, guides, technical documentation/blogs, Q&A, and
+  dialogue/instruction data;
+- run aggressive exact, normalized, and near-duplicate removal;
+- reserve the final **5-15%** of training for higher-quality sources rather than
+  the largest sources;
+- evaluate per-source perplexity and style contamination, not only global loss.
+
+Current v0.3 source-ingestion status:
+
+- `biblioteka_nauki`: prepared in the source registry as a direct-upstream
+  rebuild target with per-document license and author metadata; not included in
+  v{VERSION} parquets yet.
+- `europeana`: prepared in the source registry as a direct-upstream rebuild
+  target with per-record rights statements and creator metadata; raw SpeakLeash
+  Europeana remains excluded.
+- Europeana release policy: split conservatively at pre-1929 records for
+  US-sensitive downstream reuse, and keep later/unknown records separately
+  labeled or held until legal review.
+- `european_hplt_v3_pl`: WDS bins 10+9 are included in v{VERSION} after contract
+  validation. HPLT packaging is CC0, while underlying crawled web documents can
+  carry independent rights; downstream near-dedup and web-content review remain
+  recommended before training.
+
+Current review artifacts:
+
+- `configs/source_candidates_v0_3.json` — candidate decisions and license policy.
+- `artifacts/source_license_review_v0_3.md` — source-by-source license review.
+- `artifacts/source_candidate_audit_v0_3.md` — generated Hugging Face metadata audit.
+- `artifacts/training_mix_v0_3.md` — example 1B-token training mix with legal sources capped at 15%.
+- `artifacts/bartek_source_ingestion_plan_2026-07-02.md` — PR contract for
+  Biblioteka Nauki and Europeana ingestion.
