wikibooks: withhold 46 pages (3 copied or unlicensed pages and the Mentalizm book)

Adds the ids, with one reason each, to DROPPED_PAGES["wikibooks"] in
src/rights.py: 23933 (copy of sciaga.pl), 27715 (translation under CC BY-NC
3.0), 27602 (pasted text, source and licence lost), 26962 (non-commercial
share-alike notice) and the 42 other pages of the Mentalizm book. prepare
skips them and fails if one is not reached. Rebuilt through
fetch_wikimedia.py (prepare, build_dynaword.py, attribution, datasheet):
9,112 -> 9,066 documents, 15,571,295 -> 15,313,229 tokens; the new parquet
equals the previous one minus those 46 ids. gfdl-review.json is regenerated
(none of the 46 is among its 45 documents; only source_tokens and the share
in its summary change).

Maintainer approval 2026-10-06, relayed by the coordinator.

The fixture-dump tests now pass their own (empty) drop list to prepare, so
they no longer depend on the real lists.

+## 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.
