+## wikibooks — Polish Wikibooks (rebuild from the official dump, 3.0/4.0 labels, GFDL review)
+
+**Investigated** — 2026-10-06 (October 2026 rights audit, `artifacts/rights_audit_2026-10/reports/wikis_ugc.md`,
+`reports/citations.md` L17-26; slayerlabs/polish-dynaword-v2#57).
+
+**Verdict** — `kept`, relabelled; rebuilt from the official dump so the label follows the
+page's last revision. Documents, characters and tokens are unchanged from v0.2.5
+(9,112 / 38,892,589 / 15,571,295); the text multiset is identical. Labels per record:
+`CC-BY-SA-3.0` 4,461 documents (6,102,574 tokens, 39.2%), `CC-BY-SA-4.0` 4,651 (9,468,721,
+60.8%); v0.2.5 labelled every row 3.0. Row ids are now `wikibooks_<page id>`
+("Przewodnik po instalacji Debiana 3.0": `wikibooks_2419570` in v0.2.5, `wikibooks_1710` now);
+`author` is the page URL and `created` the last-revision date (v0.2.5: empty `author`, and
+the same range string "2004-01-01, 2025-12-31" as `created` on every row). The parquet
+`added` column is 2026-07-19 (v0.2.5: 2026-06-15).
+
+**Enumeration** — `plwikibooks-20260601-pages-articles.xml.bz2` (sha1 `198ddcbe…` matched to
+the dump's `sha1sums.txt`), parsed by `src/fetch_wikimedia.py`: 34,967 pages → 12,838 in
+namespace 0 → 1,925 redirects, 1,247 pages under 200 characters and 23 exact duplicates
+skipped → 9,643 written → 531 non-Polish dropped by `build_dynaword.py` → 9,112. Text
+conversion is the v0.2.5 one (plain `strip_code`): `<ref>` bodies, `Kategoria:` links and
+`thumb|` file options stay in the text; nothing was changed in this PR. One sidecar line per
+row (`wikibooks.attribution.jsonl`).
+
+**License evidence** — as for wikivoyage: Terms of Use oldid 554823 / 98524, the 3.0 and 4.0
+legal code, pl.wikibooks `rightsinfo` (BY-SA 4.0), read 2026-10-06. Cutoff 2023-06-07 00:00
+UTC; 2 documents were last edited that day. E1 (v2#56) is still pending.
+
+**GFDL** — 435 documents (259,065 tokens, 1.7%) were last edited before 2009-06-15 (the
+start of CC BY-SA on the Wikimedia sites, per the audit); they carry `CC-BY-SA-3.0`, counted
+and not acted on. The audit's
+"24 GFDL-mentioning documents" cannot be reproduced (its pattern is not recorded; the closest,
+`\bFDL\b|Wolnej\s+Dokumentacji`, gives 25 documents / 69,072 tokens and neither document the
+audit names). A wider case-insensitive pattern matches 45 documents (122,192 tokens, 0.78%);
+all 45 were read and sorted in `data/wikibooks/wikibooks.gfdl-review.json`: 7 state that their
+own text is under the GNU FDL (42,834 tokens), 10 name a GFDL-licensed upstream work (6,903),
+13 link the licence page only, 13 discuss licences, 2 match by accident. The largest is
+`wikibooks_30538` (35,619 tokens). No label and no drop follows from the review; the 17
+own-text and upstream documents (49,737 tokens) are the ones where a GFDL-only grant could
+matter, and keeping them is left to the maintainers and the lawyer.
+
+**Blockers** — none to merge. Open: E1; the 17 documents above. Two pages seen during the
+review and not checked: `wikibooks_27716` (145 tokens) lists third-party course sources with
+their licences, among them CC-BY-NC 3.0 and "All Rights Reserved"; `wikibooks_27071` (1,287
+tokens) says it was moved in 2013 from the "Wolne podręczniki" portal with its creators'
+consent and does not state the original licence. The markup residue above also stays.
+
+## wikibooks — 46 pages withheld (update to the section above)
+
+**Investigated** — 2026-10-06 (copyright sample and licence trace of the follow-up, then the
+maintainer's decision; slayerlabs/polish-dynaword-v2#57).
+
+**Verdict** — `kept`, 46 pages withheld. Maintainer approval 2026-10-06, relayed by the
+coordinator. The numbers in the section above (9,112 documents, 38,892,589 characters,
+15,571,295 tokens; 3.0: 4,461 / 6,102,574 tokens; 4.0: 4,651 / 9,468,721) are the v0.2.5 and
+pre-drop values; the release now holds 9,066 documents, 38,195,523 characters and 15,313,229
+tokens (3.0: 4,425 / 5,916,490; 4.0: 4,641 / 9,396,739). Withheld: 46 documents, 697,066
+characters, 258,066 tokens (36 labelled 3.0, 10 labelled 4.0).
+
+**Withheld** — `wikibooks_23933` (Historia powszechna/Rzeczpospolita pod panowaniem królów
+elekcyjnych, 10,753 tokens): copy of sciaga.pl, Earwig 0.964, 43.9% of the words, the source
+captured since 2007-10-11, the wiki page created 2011-03-28. `wikibooks_27715` (Od lamera do
+hakera/Linux, 3,761 tokens): Polish translation (Paweł Niewiadomski, linuxpl.org) of chapter
+6 of The Linux System Administrators' Guide (Lars Wirzenius, Joanna Oja); the page's own
+closing note gives CC BY-NC 3.0. `wikibooks_27602` (Od lamera do hakera/Procesor, 7,548
+tokens): text pasted on 2013-06-25, the source link lost, no licence given; Earwig suspects
+slideshare.net/slideshow/mikroprocesory/32678654 (0.896). `wikibooks_26962`
+(Mentalizm/Wprowadzenie, 1,313 tokens) and the 42 other pages of the Mentalizm book
+(234,691 tokens; hub `wikibooks_26961` included): the introduction states non-commercial
+share-alike terms (NC wording removed 2013-01-13, restored 2015-02-02); the other pages carry
+no notice of their own and are withheld with the book. Together 236,004 tokens.
+
+**Mechanism** — the ids and reasons live in `DROPPED_PAGES["wikibooks"]` in `src/rights.py`;
+`fetch_wikimedia.py prepare` skips them and fails if one is not reached. Funnel: 34,967 pages
+→ 12,838 in namespace 0 → 1,925 redirects, 1,247 short pages, 23 exact duplicates and the 46
+withheld pages skipped → 9,597 written → 531 non-Polish dropped → 9,066. Diff against the
+previous parquet: only the 46 ids removed, every other row identical. The 2 documents of the
+boundary day and the 435 GFDL-era documents are unchanged. None of the 46 is among the 45
+documents of `wikibooks.gfdl-review.json`; only its `source_tokens` (15,313,229) and the share
+in its summary (0.80%) were regenerated.
+
+**Blockers** — none. Open: the copyright sample read 79 of the 9,112 pages and 90 more by one
+contributor; `wikibooks_27716` (145 tokens, lists CC-BY-NC and all-rights-reserved sources by
+name; kept) and `wikibooks_27071` (1,287 tokens, original licence not stated; kept);
+the 25 released pages that the "Od lamera do hakera" hub links in other books were not
+traced; E1 (v2#56); the 2 boundary documents; the 17 own-text and upstream GFDL documents;
+the markup residue.

The audit counted 24 documents (0.4% of tokens) and named wikibooks_2419791 and wikibooks_2419792 (now wikibooks_3153 and wikibooks_3155); its exact pattern is not recorded and could not be reproduced: the closest pattern here, `\\bFDL\\b|Wolnej\\s+Dokumentacji`, matches 25 documents (69,072 tokens) and neither named document. A wider case-insensitive pattern matches 45 documents (122,192 tokens, 0.80% of the source's tokens); all 45 were read and sorted: 7 state that the page or book is itself under the GNU FDL (42,834 tokens), 10 name a GFDL-licensed upstream work (6,903 tokens), 13 only link the licence page in a table of contents, 13 discuss licences, 2 match by accident. No GFDL label exists in this release and no row is dropped for a GFDL mention: every row keeps the CC BY-SA label its last-revision date gives. The 17 documents in the first two groups (49,737 tokens) are the ones where a GFDL-only grant by the page's author or upstream could matter; keeping or dropping them is left to the maintainers and the lawyer.",

 ## Licensing — traceable basis
-Wikibooks content is released under CC-BY-SA 3.0; attribution + share-alike preserved.
+Contributors' text on pl.wikibooks.org is licensed CC BY-SA: [Wikimedia Terms of Use in force since 7 June 2023 (CC BY-SA 4.0)](https://foundation.wikimedia.org/w/index.php?title=Policy:Terms_of_Use&oldid=554823&action=raw); [Wikimedia Terms of Use of 2014-2023 (CC BY-SA 3.0)](https://foundation.wikimedia.org/w/index.php?title=Policy:Terms_of_Use&oldid=98524&action=raw) (read 2026-10-06 UTC). The site licence
+(`rightsinfo`) reads "Creative Commons Attribution-Share Alike 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` | 4,425 | 5,916,490 | 38.6% |
+| 2023-06-07 or later | `CC-BY-SA-4.0` | 4,641 | 9,396,739 | 61.4% |
+
+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
+2 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 citation pass's fallback) 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/rights.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`.
+
+435 documents (259,065 tokens, 1.7%) were last edited before 2009-06-15, when the Wikimedia sites
+began dual licensing under CC BY-SA 3.0 and the GFDL. Text first contributed before the 2009 move was
+under the GFDL only. They are labelled `CC-BY-SA-3.0`, so only the CC BY-SA grant is relied on; the count is recorded, not acted on.
+
+Review of GFDL mentions in the released text. The audit counted 24 documents (0.4% of tokens) and named wikibooks_2419791 and wikibooks_2419792 (now wikibooks_3153 and wikibooks_3155); its exact pattern is not recorded and could not be reproduced: the closest pattern here, `\bFDL\b|Wolnej\s+Dokumentacji`, matches 25 documents (69,072 tokens) and neither named document. A wider case-insensitive pattern matches 45 documents (122,192 tokens, 0.80% of the source's tokens); all 45 were read and sorted: 7 state that the page or book is itself under the GNU FDL (42,834 tokens), 10 name a GFDL-licensed upstream work (6,903 tokens), 13 only link the licence page in a table of contents, 13 discuss licences, 2 match by accident. No GFDL label exists in this release and no row is dropped for a GFDL mention: every row keeps the CC BY-SA label its last-revision date gives. The 17 documents in the first two groups (49,737 tokens) are the ones where a GFDL-only grant by the page's author or upstream could matter; keeping or dropping them is left to the maintainers and the lawyer. Per-document notes: `wikibooks.gfdl-review.json`.
+
+Evidence: `wikibooks.license-evidence.json`.
+
+## Attribution
+Each row's `author` is `Wikibooks contributors, <page URL>`, e.g.
+`Wikibooks contributors, https://pl.wikibooks.org/wiki/C`. The page history names the contributors; the Terms of Use (section 7b) accept a hyperlink or URL to the page as attribution.
+`wikibooks.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
+`wikibooks_<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
-Fetched directly from the official Wikimedia dump (plwikibooks-latest-pages-articles) by src/fetch_wikimedia.py; mainspace only, wikitext stripped via mwparserfromhell.
+Parsed from the official Wikimedia dump `plwikibooks-20260601-pages-articles` by
+`src/fetch_wikimedia.py`; the file (20,216,648 bytes, sha1 `198ddcbe780725b2254a930bda4d498b94a59692`) was matched against the
+dump's `dumpstatus.json` and `sha1sums.txt` (`wikibooks.build.json`). v0.2.0-v0.2.5 used the same dump
+date; the text set is the same except for the withheld pages (the rebuild adds the last-revision time).
+
+Articles (namespace 0) only. Redirects, empty pages and pages shorter than 200 characters are skipped.
+Wikitext is converted with mwparserfromhell `strip_code(normalize=True, collapse=True)`, as in v0.2.5.
+Templates and comments are dropped. `<ref>` bodies, category links (`Kategoria:...`) and file-link
+options (`thumb|...`) are not removed and stay in the text; the wikipedia fetcher's `strip_article`
+removes them, this one does not, because that would change the text set. Of two pages with the same

 ## Statistics
 | documents | characters | tokens (tiktoken proxy) |
 |---:|---:|---:|
-| 9,112 | 38,892,589 | 15,571,295 |
+| 9,066 | 38,195,523 | 15,313,229 |
 
+v0.2.5 had 9,112 documents, 38,892,589 characters and 15,571,295 tokens; the difference is the 46 pages withheld by the rights review.
 
 ## Per-document license metadata
 | license | documents |
 |---|---:|
-| `CC-BY-SA-3.0` | 9,112 |
+| `CC-BY-SA-3.0` | 4,425 |
+| `CC-BY-SA-4.0` | 4,641 |
 
-Author metadata present for **0** documents. Empty values mean the upstream record did not expose a machine-readable author field.
-
-Statistics were recomputed directly from the released parquet file.
+Author metadata present for **9,066** documents.
 
 ## 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**
+- drop documents < 200 chars: **0** (the fetcher already dropped 1,247)
+- drop non-Polish (diacritic ratio): **531**
 - exact cross-source dedup (sha1): **0**
 - OCR alpha-ratio < 0.70 (OCR sources only): **0**
-- read 9,112 → kept 9,112
+- read 9,597 → kept 9,066
 
 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 (no sample was run)
+- 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;
+  the lawyer's answer to E1, the wiki 3.0/4.0 labelling, is still pending), and the time of day of the switch
+- text imported from elsewhere under another licence or with extra attribution requirements
+- 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)
+- personal data (the NERGAL scrub runs before release)
