Merge origin/main (PRs 67, 70, 68) into sejm_api provenance

source_findings.md conflict: both sides appended sections; main's wolne_lektury,
1000_novels and wikipedia sections kept first, then the sejm_api section. No data overlap.

+## wolne_lektury — eltec_pol duplicates dropped (2026-10-06)
+
+**Verdict** — kept, 63 documents dropped: 6,141 → 6,078 documents, 103,009,797 →
+90,654,820 tokens (input: the v0.2.5 Parquet, unchanged since v0.2.1). Each dropped
+document is a novel, or one tome of a novel, that `eltec_pol` also carries. 50 ELTeC
+novels are concerned, and `eltec_pol` stays whole (maintainer decision A,
+polish-dynaword-v2 #72). The filter is `src/clean_wolne_lektury.py` and the pair list is
+`data/wolne_lektury/wolne_lektury.eltec_pairs.tsv`.
+- Score: the share of a WL document's 5-word shingles found in the ELTeC novel that
+  shares the most with it. Tokenisation follows `near_dedup`, and a trailing WL footer is
+  cut first (no WL row has one). Containment is used, not Jaccard, because WL splits
+  novels into tomes: Chłopi has 4, Faraon, Nad Niemnem and Stara baśń have 3.
+- Threshold 0.9, in an empty stretch: no document scores between 0.7588 and 0.9636. All
+  63 documents above it pair with an ELTeC novel by the same author and title (Żuławski's
+  two WL documents are headed with the trilogy's title).
+- Hand-checked: all 3 documents between 0.3 and 0.9, the 3 between 0.9 and 0.99, and 10
+  sampled at ≥ 0.99 (seed 72). In 12 of the 13 drops checked, the unmatched shingles
+  form short scattered runs of at most 27 words (title head, spelling variants). The
+  exception is Dzieje grzechu (0.9879): its WL copy ends with a "Dodatek" of draft
+  chapters, about 1,800 words that ELTeC lacks. It is dropped with the novel.
+- Kept and listed as `keep_partial`: both WL tomes of Mniszek's Trędowata (0.7588 and
+  0.6473 against POL0051). The ELTeC text is shorter: about 121,000 words against WL's
+  162,000. 95% of the ELTeC shingles are in WL's tomes, and the WL text missing from
+  ELTeC comes in runs of up to 5,418 words. The shared part stays duplicated across the
+  two sources. Also kept: Kochanowski's Pieśń IX from Pieśni, księgi wtóre (0.4267),
+  which Łoziński's Oko proroka quotes.
+- Below 0.3 (not listed, not dropped): 6 documents at 0.10–0.22, all poems of at most
+  2,321 tokens by Mickiewicz, Kochanowski and Miciński; their overlap with the paired
+  novels was not inspected. Nothing scores between 0.2203 and 0.4267.
+
+**Reason** — 51 of the 100 ELTeC novels duplicate WL texts. ELTeC's CC BY 4.0 licence
+is the clean one (`rights_audit_2026-10/reports/literary.md`: eltec_pol CLEAN). WL
+licence labels are not touched here; #57 relabels them per row.
+
+References: polish-dynaword-v2 #72 (decision), #45 (method);
+`rights_audit_2026-10/literary/eltec_meta.tsv` (ELTeC file names and titles).
+
+**Lesson** — Jaccard near-dedup misses a novel that one source splits into tomes.
+Measure containment from the split side.
+
+## 1000_novels — wolne_lektury and eltec_pol duplicates dropped (2026-10-06)
+
+**Verdict** — kept, 666 texts dropped: 887 → 221 documents, 130,201,301 → 26,625,861
+characters, 51,981,548 → 10,759,728 tokens (input: Hub PR 65; references: main at
+563eea8, after Hub PR 67). Each dropped text is already in `wolne_lektury` (629) or
+`eltec_pol` (37); none is in both, since Hub PR 67 dropped the WL copies of ELTeC novels
+(before it, 35 of the 37 were in both). Maintainer decision on polish-dynaword-v2 #45:
+drop the 1000_novels copy and keep both other sources whole. The filter is the dedup
+step of `src/clean_1000_novels.py`, run after the rights screen. Covers and matched ids
+for all 887 screened texts are in `data/1000_novels/1000_novels.dedup.tsv`.
+- Cover: the share of a text's 5-word shingles found in any document of one source
+  (`src/shingle_containment.py`, shared with `src/clean_wolne_lektury.py`; near_dedup
+  tokenisation; a trailing Wolne Lektury footer cut first). Scored per source, over the
+  union of its documents: 7 texts are duplicates only across several WL documents. For
+  example, *Popioły* (`1000_novels_0953`) is in 3 WL tomes, none above 0.33, together 0.9602.
+- Threshold 0.5, in empty stretches: no text covers between 0.0727 and 0.5178 against
+  `wolne_lektury`, or between 0.0462 and 0.7771 against `eltec_pol`. Both reference
+  Parquets are pinned by SHA-256 (main's: wolne_lektury after Hub PR 67, eltec_pol
+  unchanged since v0.2.1).
+- Hand-checked every text between 0.3 and 0.7, plus `0703`. All are dropped.
+  - `0255` Grabiński, *Spojrzenie* (0.6721): the same story. Soft-hyphen word breaks
+    ("opuści ła") lower the cover evenly; no unmatched run exceeds 20 shingles.
+  - `0388` Laclos, *Niebezpieczne związki* (0.6975 over two WL tomes, 0.41 and 0.29): the
+    whole 1912 Boy translation in old spelling, which lowers the cover throughout (0.51–0.88
+    per tenth of the text). The longest unmatched run is the collected footnotes at the
+    end (420 shingles).
+  - `0509` Orzeszkowa, *Bóg wie kto* (0.6291): a 1909 serial instalment, 2,342 of WL's
+    6,677 words, in old spelling; no unmatched run exceeds 28 shingles.
+  - `0891` Verne, *Przygody trzech Rossyan…* (0.5383): the same Anczyc translation. Old
+    spelling ("é") lowers the cover evenly; no unmatched run exceeds 49 shingles.
+  - `0703` Reymont, *Chłopi* (ELTeC 0.8259; WL 0.8272 before Hub PR 67 dropped its 4
+    tomes, 0.0030 after): an abridged edition of about 43,000 words in old spelling; no
+    unmatched run exceeds 25 shingles.
+  - `0493` Orkan, *Listy ze wsi* (0.5178 against WL's *Płanety*): sections I and II match
+    at 0.76–0.90 per tenth of the text. The last section (IV, about 1,100 words) is not in
+    WL and is lost with the drop.
+  - 10 drops sampled with seed 45 (all WL): 98.3–100% of each text's shingle positions
+    match; the longest unmatched run is 85 shingles (the footnotes of `0508`).
+- Kept texts: none carries a Wolne Lektury footer. 4 share author and title with a WL
+  document but are other texts: Balzac's *Kobieta trzydziestoletnia* (`0065`, Marrene's
+  translation; WL has Boy's; 0.0388), Grabiński's *Na wzgórzu róż* (`0239`, 0.0043),
+  Kraszewski's *Dziad i baba* (`0359`, a prose tale; WL has the poem; 0.0079) and
+  Przybyszewski's *Nad morzem* (`0690`; WL has a 354-word piece; 0.0303).
+- Hub PR 67 (#72) merged first. Re-pinned to its wolne_lektury Parquet (SHA-256
+  `f308d492…`, was `5833c25d…`) and rebuilt: the same 666 drops and the same Parquet. The
+  split went from WL 664, ELTeC 37, both 35 to WL 629, ELTeC 37, both 0; 216 WL covers
+  change. The 5 texts hand-checked between 0.3 and 0.7 and the 10 sampled drops stay WL
+  drops.
+
+**Reason** — 666 of the 887 public-domain texts, 41.2M tokens, are copies of documents
+that `wolne_lektury` or `eltec_pol` already release.
+
+References: polish-dynaword-v2 #45 (measurement and decision), #72 (wolne_lektury side).
+
+**Lesson** — score against the union of a source's documents. Wolne Lektury splits
+novels into tomes, and no single tome need hold half of the text.
+
+## wikipedia — Polish Wikipedia (rebuild from the official dump)
+
+**Investigated** — 2026-10-05 (October 2026 rights audit, `artifacts/rights_audit_2026-10/reports/wikis_ugc.md`
+L44-46, `reports/citations.md` L17, `reports/citations/wikimedia.md` section 5;
+slayerlabs/polish-dynaword-v2#69).
+
+**Verdict** — `added`, rebuilt for v0.2.6 from the official Wikimedia dump; the SpeakLeash
+`plwiki` intermediary is removed. 1,468,656 documents / 3,140,841,847 characters /
+1,226,913,508 tokens (v0.2.5: 1,171,897 / 1,844,707,761 / 707,194,207). Labels per record by
+the page's last revision: `CC-BY-SA-3.0` 190,837 documents (6.6% of tokens), `CC-BY-SA-4.0`
+1,277,819 (93.4%); v0.2.5 labelled every row 3.0. Row ids are now `wikipedia_<page id>`
+("Bitwa pod Grunwaldem": `wikipedia_25295` in v0.2.5, `wikipedia_716` now).
+
+**Enumeration** — `plwiki-20260901-pages-articles`, 7 shards, each sha1 matched to the
+dump's `dumpstatus.json` and `sha1sums.txt`, parsed by `src/fetch_wikipedia.py`: 2,877,278
+pages → 2,304,425 in namespace 0 → 598,071 redirects and 35 pages with `{{NPA}}`
+(`{{Copyvio}}`, `{{Plagiat}}`) skipped → 1,706,319 converted → 382 exact duplicates →
+231,717 under 200 characters and 5,564 non-Polish dropped by `build_dynaword.py` →
+1,468,656. One sidecar line per row (`wikipedia.attribution.jsonl`: page id, revid, title,
+URL, last-revision time, licence).
+
+**License evidence** — verified, read 2026-10-05: Terms of Use oldid 554823 (CC BY-SA 4.0
+and GFDL, in effect June 7, 2023; sha256 `c96ef93b…`), oldid 98524 (CC BY-SA 3.0, June 16,
+2014), the 3.0 and 4.0 legal code, pl.wikipedia `rightsinfo` (BY-SA 4.0). Inferred: a page
+edited after the switch may carry its earlier 3.0 text under 4.0 (3.0 §4(b)(ii)). The
+cutoff is 2023-06-07 00:00 UTC, not the audit's "06-08 if time of day unknown": 06-08 would
+put that day's 4.0 edits under 3.0, which 4.0 §3(b)(1) does not allow; midnight may put
+3.0 text under 4.0 for some of the 184 pages last edited that day. The footer switch date
+was not checked. Evidence in `data/wikipedia/wikipedia.license-evidence.json`.
+
+**Copyright pastes** — the 31 notice pages unchanged since the dump were re-read: all carry
+the notice; 4 edited since were not re-read. Web sample of 40 released pages per label
+(seed 20261006, Earwig's Copyvio Detector, every hit from confidence 0.10 read by hand):
+1 of 40 per label copied or closely paraphrased from a copyrighted source
+(`wikipedia_833396` "Obnażyć prawdę", Filmweb's official description; `wikipedia_1126780`
+"Czarnka", the Drawieński Park Narodowy lake text archived 2012), 6 later copies of
+Wikipedia, 2 shared titles or stock phrases, 70 below the threshold. 95% Wilson upper
+bound 12.9% per label. Both pages are kept in this release; dropping them is an open
+decision. Per page in `data/wikipedia/wikipedia.copyvio-sample.jsonl`.
+
+**Dedup checks** — reported, not fixed. Exact-text overlap (SHA-256 of raw text) with NKJP1M
+(main and v0.2.5) and HPLT v0.2.5 is 0 documents (v0.2.5: NKJP1M–Wikipedia 1, HPLT–Wikipedia
+6). Near duplicates not measured. The `overlap_audit.json` files of `plwiki_talk` and others
+compare literal ids against the old `data/wikipedia` (revision `fe44303`, 1,171,897 rows) and
+are stale after the id change.
+
+**Blockers** — none to merge. Open: the two pasted pages; the time of day of the 4.0 switch;
+GFDL-era text; `{{ek}}` pages kept; appendix headings left in 56.4% of documents (2.96% of
+characters from the first such heading on) and whitespace-only lines in 11.9%; NERGAL pass
+before release.
+
+**Lesson** — (1) Earwig rated a close paraphrase "none" (0.30): hand-check below its
+"possible" threshold. (2) Earwig's best hit is usually a later copy of Wikipedia; the real
+source came from the article's own citation and history ("Czarnka": a 2025 forum hit, the
+park's 2012 text behind it). (3) The Terms of Use give the day of the licence switch, not
+the time, so a last-revision label is inexact for one day of edits.
+
+## wikipedia — update: copied pages and `{{ek}}` dropped
+
+Drops added to `src/fetch_wikipedia.py` (`prepare`), keyed on the wiki page id; the dump
+(plwiki 20260901) is unchanged. `COPIED_PAGES`: page 833396 "Obnażyć prawdę" (Filmweb's
+official description; excluded) and page 1126780 "Czarnka" (Drawieński Park Narodowy lake
+text; held for review, Art. 4 not assessed). The build fails if a listed page is not reached.
+
+`{{ek}}` (speedy deletion; aliases EK, Ekspresowe kasowanko, Usuń, Speedy, Delete from the
+dump's redirects) is read with its reason; a reason naming a copyright violation (npa,
+plagiat, copypaste, kopiuj-wklej, copyvio, "praw… autorsk…") drops the page. The dump has 0
+live `{{ek}}` notices on articles, so 0 dropped and no reasons to count; a looser text scan
+of all 7 shards found 3, all inside `<!-- -->` comments (redirect, content moved, no
+reason), none about copyright. The hand-check of 10 was not possible.
+
+Rebuilt from the same dump: 1,468,656 → 1,468,654 documents, 1,226,913,508 → 1,226,912,191
+tokens (3.0: 190,836 docs / 81,022,938 tokens; 4.0: 1,277,818 / 1,145,889,253). Diff against
+the previous parquet: only `wikipedia_833396` and `wikipedia_1126780` removed, no row added
+or changed, same in the attribution sidecar. Row order differs between builds
+(`build_dynaword.py` uses `imap_unordered`); content per id is identical. The copyright
+sample keeps its population (the previous build) and records the two dropped ids.
+
 ## sejm_api — provenance relabelled (2026-10-06)

 ## Licensing — traceable basis
-Wikimedia dumps explicitly released under CC-BY-SA 3.0; attribution to contributors + share-alike preserved.
+Wikipedia contributors license their text under CC BY-SA 4.0 under the Wikimedia
+[Terms of Use](https://foundation.wikimedia.org/w/index.php?title=Policy:Terms_of_Use&oldid=554823) in effect since 7 June 2023, and under CC BY-SA 3.0 under the
+[2014-2023 Terms of Use](https://foundation.wikimedia.org/w/index.php?title=Policy:Terms_of_Use&oldid=98524) (both read 2026-10-05 UTC). The pl.wikipedia site licence
+(`rightsinfo`) links BY-SA 4.0. Each row is labelled by its page's last revision in the
+dump:
+
+| last revision (UTC) | `license` | documents | tokens | share of tokens |
+|---|---|---:|---:|---:|
+| before 2023-06-07 | `CC-BY-SA-3.0` | 190,836 | 81,022,938 | 6.6% |
+| 2023-06-07 or later | `CC-BY-SA-4.0` | 1,277,818 | 1,145,889,253 | 93.4% |
+
+A page last edited on or after the cutoff can still hold 3.0 text from earlier edits;
+[CC BY-SA 3.0](https://creativecommons.org/licenses/by-sa/3.0/legalcode) §4(b)(ii) lets such an adaptation be licensed under "a later
+version of this License with the same License Elements", so it is labelled 4.0. The Terms
+of Use give the day of the switch, not the time. The cutoff is midnight UTC, so the
+184 pages last edited on 2023-06-07 itself are labelled 4.0. If the switch came later
+that day, those last edited before it are 3.0 text under a 4.0 label; a 2023-06-08 cutoff
+(the rights audit's suggestion) would instead put that day's 4.0 edits under a 3.0 label,
+which [4.0](https://creativecommons.org/licenses/by-sa/4.0/legalcode) §3(b)(1) ("this version or later") does not allow. Neither choice is
+exact without the time of the switch. The rule is `license_for_revision` in `src/fetch_wikipedia.py`,
+tested at the cutoff second, across time zones, and on a missing timestamp, which stops the
+build. v0.2.0-v0.2.5 labelled every row `CC-BY-SA-3.0`.
+
+Text pasted into an article from a copyrighted source is under neither licence. The
+fetcher drops the 35 pages that carry plwiki's copyright-violation
+notice `{{NPA}}` (or its redirects `{{Copyvio}}`, `{{Plagiat}}`) in the dump.
+On 2026-10-05 the 31 of them not edited since the dump were re-read on
+pl.wikipedia: all carry the notice (some mark one section only; the whole page is dropped).
+The 4 edited after the dump were not re-read. Pages tagged for speedy deletion with
+`{{ek}}` (or its redirects `{{Delete}}`, `{{EK}}`, `{{Ekspresowe kasowanko}}`, `{{Speedy}}`, `{{Usuń}}`) are also
+dropped when the stated reason is a copyright violation (`EK_COPYRIGHT_RE`: the
+template's codes `npa`, `plagiat`, `copypaste`, `kopiuj-wklej`, or free text with "copyvio" or
+"praw autorskich"). No article in this dump carries a live `{{ek}}` notice; a looser
+scan found 3 inside HTML comments, which MediaWiki does not show and the build does not
+count. A paste without either notice cannot be detected by the build.
+
+To measure undetected pastes, 40 released pages per label (seed
+20261006, page-id order) were run through Earwig's Copyvio Detector (web search and
+the page's external links) on 2026-10-05. Every page whose best match reached
+confidence 0.10 or a "possible"/"suspected" verdict was compared by hand
+with the page history and the date of the matching text (see `wikipedia.copyvio-sample.jsonl`):
+
+| result | `CC-BY-SA-3.0` | `CC-BY-SA-4.0` |
+|---|---:|---:|
+| best Earwig confidence below 0.10 and no possible/suspected verdict; not read by hand | 37 | 33 |
+| shared text on a later page that copies Wikipedia | 2 | 4 |
+| shared text is only a title, a name or a stock phrase, not prose | 0 | 2 |
+| text copied or closely paraphrased from a copyrighted source | 1 | 1 |
+
+1 of 40 (`CC-BY-SA-3.0`) and 1 of 40 (`CC-BY-SA-4.0`) pages contain text
+copied or closely paraphrased from a copyrighted source: `wikipedia_833396` "Obnażyć prawdę" (`CC-BY-SA-3.0`); `wikipedia_1126780` "Czarnka" (`CC-BY-SA-4.0`) (the sample file notes
+why each is classed so). Both are dropped from this release: `COPIED_PAGES` in
+`src/fetch_wikipedia.py` lists them by page id with the reason, and the build stops if one is
+not found. The sample was drawn before that drop, from the 1,468,656 documents of Hub PR 68
+commit 3393e05; the test reproduces the draw from the release plus the dropped rows. The share of such pages is below 12.9% (`CC-BY-SA-3.0`) and
+12.9% (`CC-BY-SA-4.0`), 95% Wilson upper bounds; the labels hold
+6.6% and 93.4% of the tokens. The bounds cover only
+what the detector can find: print sources, translations and paraphrase scoring below the
+hand-check threshold cannot match.
+
+Evidence: `wikipedia.license-evidence.json`.
+
+## Attribution
+Each row's `author` is `Wikipedia contributors, <page URL>`, e.g.
+`Wikipedia contributors, https://pl.wikipedia.org/wiki/Warszawa`. The page history names the contributors; the Terms of Use
+(section 7) accept a link or URL to the page as attribution.
+`wikipedia.attribution.jsonl` has one line per row: `id`, `pageid`, `revid` (the revision
+in the dump), `title`, `url`, `last_revision_at`, `license`. The row `id` is
+`wikipedia_<page id>` and `created` is the date of `last_revision_at`.
+
+The text is modified: wiki markup is converted to plain text (see Provenance).
 
 ## Provenance
-Pulled from SpeakLeash's public redistribution (`speakleash-ds-pub`, key `plwiki`) of the upstream source above. SpeakLeash credited as intermediate aggregator; upstream license/attribution preserved.
+Parsed from the official Wikimedia dump `plwiki-20260901-pages-articles` by
+`src/fetch_wikipedia.py`: 7 shards, whose names, sizes and sha1 are in
+`wikipedia.build.json`, each matched against the dump's `dumpstatus.json` and
+`sha1sums.txt`. v0.2.0-v0.2.5 used the SpeakLeash `plwiki` snapshot
+(`speakleash-ds-pub`); that intermediary was removed in this rebuild.
+
+Articles (namespace 0) only. Redirects, empty pages and pages with a copyright-violation
+notice are skipped; pages listed in `COPIED_PAGES` or with a copyright `{{ek}}` reason are
+dropped after the duplicate check, so a copy of their text on another page goes with them. Wikitext is converted with mwparserfromhell
+`strip_code(normalize=True, collapse=True)`, as in the sibling Wikimedia builders, after
+removing `<ref>` bodies, file and category links and behaviour switches (`__NOTOC__`).
+Templates (infoboxes, navigation boxes), `<math>`, galleries and comments are dropped;
+table cells stay as flattened text; section headings stay as their own line. Of two
+pages with the same text (sha1 of the stripped text), the lower page id is kept.
+
+2,877,278 pages scanned → 2,304,425 in namespace 0 → 598,071 redirects,
+0 empty pages and 35 with a copyright-violation notice skipped
+(0 parser failures) → 1,706,319 converted →
+382 exact duplicates, 2 copied pages (`COPIED_PAGES`) and 0 copyright `{{ek}}`
+pages dropped → 1,705,935 read by the build →
+1,468,654 released.
+
+Not cleaned: appendix headings ("Zobacz też", "Uwagi", "Przypisy", "Bibliografia", "Linki
+zewnętrzne") stay in 828,388 documents (56.405%), with what is left of those sections
+after the conversion (2.96% of all characters from the first such heading to the end);
+174,668 documents (11.893%) have whitespace-only lines.

+v0.2.5 (SpeakLeash snapshot) had 1,171,897 documents, 1,844,707,761 characters and
+707,194,207 tokens. The SpeakLeash extraction is not documented. Its text drops the
+appendix sections (a line reading only "Przypisy", "Bibliografia", "Linki zewnętrzne" or
+"Zobacz też" occurs in 65 of its 1,171,897 documents) and, on the page compared, lists: "Bitwa pod Grunwaldem" is 37,234 characters
+in v0.2.5 and 59,133 here.

 ## Filters applied (build_dynaword.py)
-Minimal, per Dynaword guidelines (heavy filtering left to downstream use):
-- drop documents < 200 chars: **0**
-- drop non-Polish (diacritic ratio): **0**
-- exact cross-source dedup (sha1): **0**
+- drop documents < 200 chars: **231,717**
+- drop non-Polish (diacritic ratio): **5,564**
+- exact cross-source dedup (sha1): **0** (the fetcher already dropped 382)
 - OCR alpha-ratio < 0.70 (OCR sources only): **0**
-- read 1,171,897 → kept 1,171,897
+- read 1,705,935 → kept 1,468,654
 
 Token counts are a fast tiktoken (cl100k) proxy (~1% off Llama-3); the canonical
 Llama-3 count is computed at release.
+
+## Not checked
+- pastes from copyrighted sources beyond the sample above
+- the 3.0 → 4.0 label of pages edited after the cutoff (a reading of 3.0 §4(b)(ii), not a
+  lawyer's opinion), and the time of day of the switch (184 pages last edited on 2023-06-07)
+- text imported from elsewhere under another licence or with extra attribution
+  requirements (Terms of Use, Re-use); notices kept in templates are removed by the conversion
+- text first contributed under GFDL before the 2009 move to CC BY-SA, and GFDL dual
+  licensing; only the CC BY-SA grant is relied on
+- quotations inside articles (Art. 29 of the Polish copyright act)
+- deletion discussions and maintenance notices other than `{{NPA}}` and `{{ek}}`; their
+  reasons are not read
+- personal data (the NERGAL scrub runs before release)
