 # Changelog
 
+## v0.2.5 (2026-08-14)

+- 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: 4,319,200 documents and 9,639,062,573

+# samorzad_gov_pl
+
+Polish-language articles published by 246 local public institutions and one
+central platform tenant using the shared
+[samorzad.gov.pl](https://samorzad.gov.pl/) platform. The collection includes
+municipalities, counties, schools, social-service institutions, cultural
+institutions and other public bodies.
+
+## Dataset description
+
+- **Published source dataset:** https://huggingface.co/datasets/dawidmajewski/samorzad-gov-pl-articles
+- **Source revision:** `d5eaefc32c3f17cfa5a01d14573f8e4ee7d43385` (`v0.1`)
+- **Original platform:** https://samorzad.gov.pl/
+- **Domain:** local government, education, social services and culture
+- **Language:** Polish (`pl`)
+- **License:** `CC-BY-SA-4.0`
+- **Created:** 2020–2026 for dated records; most source records do not expose a date
+- **Added:** 2026-08-14
+
+## Statistics
+
+| read | kept | characters | tokens (`cl100k_base` proxy) | publishers |
+|---:|---:|---:|---:|---:|
+| 81,422 | 72,771 | 109,513,754 | 41,154,506 | 247 |
+
+The released Parquet uses the canonical DynaWord schema:
+
+`id, text, source, added, created, token_count, license, author`
+
+Every retained document has the human-readable name of its publishing
+institution in `author`. The names were obtained from the `og:site_name`
+metadata on each institution's platform homepage and frozen in
+`src/samorzad_gov_pl_publishers.json`.
+
+## Provenance
+
+The source release was collected directly from public samorzad.gov.pl pages.
+It contains every article URL found and successfully extracted during that
+crawl, rather than a topical or length-selected sample. The published source
+release contains 81,422 extracted articles from 247 institutions.
+
+`src/clean_samorzad_gov_pl.py` converts the published source Parquets into the
+DynaWord schema, applies the common minimum-length and Polish-language checks,
+removes exact duplicate text and counts tokens with `cl100k_base`. The retained
+article text is otherwise unchanged.
+
+## Licensing — traceable basis and attribution
+
+The platform's shared footer states that textual content published in the
+service, excluding audiovisual content, is available under CC BY-SA 4.0. A
+release-time audit verified the live shared footer script and confirmed that
+all 81,422 preserved source pages referenced that script. The evidence URL,
+byte count and SHA-256 digest are recorded in
+`samorzad_gov_pl.license-evidence.json`.
+
+The fixed DynaWord schema does not contain article titles or URLs. Therefore,
+`samorzad_gov_pl.attribution.jsonl` maps every released `id` to its title,
+discovered `source_url`, fetched `final_url`, recommended `attribution_url`,
+publishing institution, platform tenant, license URL and modification notice.
+For 693 retained records the discovered and final URLs differ because the
+platform redirected the request; `attribution_url` uses the fetched final URL.
+
+Recommended attribution:
+
+> Publishing institution listed in the `author` column; article title and
+> canonical samorzad.gov.pl URL from the attribution sidecar; CC BY-SA 4.0.
+> Article text was extracted from HTML and normalized for inclusion in Polish
+> DynaWord.
+
+Photographs, recordings, videos and attachment bytes are not redistributed.
+The source platform gives audiovisual materials separate terms, and linked
+attachments can carry their own conditions. URLs and descriptive metadata do
+not redistribute those files.
+
+## Filters applied
+
+| result | documents |
+|---|---:|
+| source records read | 81,422 |
+| shorter than 200 characters | 6,624 |
+| below the Polish-language heuristic | 35 |
+| exact duplicate text | 1,992 |
+| retained | 72,771 |
+
+Exact duplicate removal is performed after short-text and language checks.
+Existing DynaWord sources take priority when the same text is already present
+elsewhere in the corpus.
+
+## Limitations and recommended use
+
+- The collection is not a complete historical archive of samorzad.gov.pl. It
+  contains the pages found and successfully extracted during one crawl.
+- Only 21,892 of the 81,422 source records expose a publication date. After
+  filtering, 52,214 retained records have an empty `created` value; no date is
+  inferred for them.
+- The source text can contain spelling errors, extraction remnants or captions.
+- Very short source records are excluded by DynaWord's 200-character minimum.
+- Institution names describe the publishing body, not necessarily the person
+  who wrote an article.
+- Government and institutional language is overrepresented; this source should
+  complement, not stand in for, conversational or general Polish.
+- Canonical URLs may stop working as institutions update their websites.
+
+## Included files
+
+- `samorzad_gov_pl.parquet` — canonical DynaWord records;
+- `samorzad_gov_pl.stats.json` — build and release statistics;
+- `samorzad_gov_pl.attribution.jsonl` — per-document source attribution;
+- `samorzad_gov_pl.license-evidence.json` — release-time license evidence;
+- `NOTICE.md` — attribution and redistribution notice.
+
+## Reproduction
+
+The converter refuses to build unless the downloaded `manifest.json` and all
+10 Parquet shards match the pinned release. It verifies the manifest SHA-256,
+artifact set, shard sizes and SHA-256 values, row counts, schema, unique record
+IDs and the release-wide record-text digest before conversion. Outputs are
+written to temporary files, cross-checked, synced and transactionally replaced;
+a failed replacement restores the previous artifact set.
+
+Download the published source Parquet shards and run:
+
+```bash
+hf download dawidmajewski/samorzad-gov-pl-articles \
+  --repo-type dataset \
+  --revision d5eaefc32c3f17cfa5a01d14573f8e4ee7d43385 \
+  --include 'data/*.parquet' --include manifest.json \
+  --local-dir /tmp/samorzad-gov-pl-articles
+
+uv run --with pyarrow --with tiktoken python src/clean_samorzad_gov_pl.py \
+  --input /tmp/samorzad-gov-pl-articles/data \
+  --repo-root . \
+  --added 2026-08-14
+```
+
+Use `--refresh-publishers` only when intentionally updating the frozen
+institution-name manifest from live tenant homepages. Review any changed name
+before publishing a new release.
