Merge origin/main (samorzad_gov_pl #64, global_voices) into v026-1000_novels

Conflict in artifacts/source_findings.md resolved by keeping every entry:
main's samorzad_gov_pl and global_voices sections, then the 1000_novels section.

 **Lesson** — an open-licence footer covers the publisher's own text. On a news-style
 site, check source lines for agency copy before taking the footer at face value.
 
+## samorzad_gov_pl — third-party slices dropped (2026-10-06)
+
+**Verdict** — kept, relabelled, 144 rows dropped: 72,472 → 72,328 documents,
+40,011,099 → 39,890,244 tokens (baseline: main after #46, not the v0.2.5 tag's
+72,771). The basis is now called an operator-declared platform licence. A question
+to KPRM is pending (polish-dynaword-v2 #49); its answer may still change the
+source's status. The drops are in `src/clean_samorzad_gov_pl.py`
+(`third_party_drop`, applied by `--refilter-release` to the pinned release):
+- 69 "Piątek z poezją" posts (all Powiat Sokołowski): poems credited to their
+  authors. All 69 hand-checked.
+- 9 IMGW-PIB notices carrying "Opracowanie niniejsze i jego format…", which forbids
+  changes and requires naming IMGW-PIB. All 9 hand-checked.
+- 66 articles whose `Źródło:` line credits a non-governmental source (Wikipedia,
+  media, associations including volunteer fire brigades, foundations, clubs, rural
+  housewives' circles, companies, named books or brochures), unless a photo or film
+  marker precedes it on the line. All 66 hand-checked as third-party text. The rule
+  was revised on the same matches (first pass 61 of 67 correct), so precision is
+  in-sample and recall is unknown; one known miss is a Fundacja Santander credit.
+  Part of the regex lists work titles found in that review.
+- Not dropped: contest entries. The issue's 112 is not reproducible; the closest
+  regex (awarded/winning/distinguished works) gives 111 documents, and a 40-document
+  sample (seed 49) contains no entry text: they are results announcements. Only 3
+  documents publishing entries were found; most entries are images, not text.
+
+**Reason** — gov.pl's copyright page says the service also carries third-party works
+whose use requires the owners' consent; the footer licence cannot cover them.
+Credits matter here: 810 documents have an `Źródło:` line, but in 405 every credit is
+only a de-identified `<URL>`, so their sources cannot be classified; 231 documents
+mention IMGW without the verbatim notice and were not reviewed.
+

+
+**Lesson** — de-identification that replaces URLs also removes the provenance needed
+to screen reposts. Record the credited domain before masking URLs.
+
+## global_voices — partner republications dropped (2026-10-06)
+
+**Verdict** — `admitted` with 114 posts withheld (polish-dynaword-v2 #50). The source
+goes from 2,040 docs / 10,073,628 chars / 3,715,020 tokens to 1,926 / 9,358,071 /
+3,453,918. The posts come from 51 outlets. The new `src/clean_global_voices.py` filters
+the v0.2.5 Parquet and sidecar, pinned by SHA-256. `src/test_global_voices_contract.py`
+checks that no shipped row matches the rule.
+
+**Reason** — Global Voices licenses "content created by Global Voices" under CC BY 3.0.
+A post that republishes a partner's article under a content-sharing agreement or with
+permission stays the partner's work.
+- **Where the rule looks.** It reads only the first 700 and last 350 characters, where
+  the editorial note sits. A rule fires only on a sentence about the post itself that
+  does not name Global Voices, so news reporting ("raport opublikowany przez UNESCO")
+  and GV's own projects do not count. Sentences whose subject is an image are skipped
+  too.
+- **Rule counts** (a post can match several):
+  - originally: 69
+  - agreement: 56
+  - published_by: 51
+  - partnership: 11
+  - permission: 5
+  - republished: 5
+  - written_for: 3
+  - non_commercial: 3
+  - listed by hand: 3 (21466, 27005, 32352)
+- **Hand check.**
+  - Every one of the 114 drops was read, and the English original was consulted where
+    the note was unclear.
+  - 25 rule matches are kept by hand with a stated reason:
+    - 12 cross-posts from the author's own blog;
+    - 7 posts GV wrote for the ISN blog;
+    - 3210, a GV post that another outlet republished;
+    - 2 notes dating GV's own English original;
+    - 3 news mentions.
+  - All 43 posts where the gating removed a raw match were checked. They are image
+    credits, news and GV projects.
+  - 15 partner-organisation accounts with no republication note (e.g. 350.org 22567,
+    Metamorphosis 33071) were checked against the English page and kept.
+- **Outlets.**
+  - PRI/The World 21
+  - The Stand News 8
+  - Hong Kong Free Press 7
+  - Agência Pública 6
+  - Metamorphosis/Meta.mk 5
+  - 350.org 5
+  - Eurasianet 3
+  - Freemuse 3
+  - The Irrawaddy 3
+  - 2 each: Balkan Diskurs, Ensia, Kurtural, Loa, MigraMundo, NACLA, Nepali
+    Times/Himalkhabar, Premium Times, Syria Untold, Teplitsa, Transitions
+  - 1 each: 88 Bar, APC.org, Afroféminas, Azerbaijan Internet Watch, Baynana, Bumaga,
+    CHRI, Cari-Bois, Chaikhana, Common Dreams, Connectas, Doha News, Fundación MEPI,
+    GCHR, Hive-Mind/EJO, Iran Voices, New America Media, OC Media, Periodismo de
+    Barrio, Promundo, Russia Post, Sin Embargo, Syria Deeply, TJournal, Tea After
+    Twelve, The Isaan Record, The Moscow Times, VideoVolunteers, WITNESS,
+    inmediahk.net, openDemocracy.
+- **Delta against the audit's 64.** The audit used outlet names plus an agreement
+  regex, and it recorded neither the list nor the script. Its "17 PRI" is an
+  undercount: all 21 posts credited to PRI/PRX's The World carry a republication note.
+  Most of the remaining difference is outlets the audit's name list did not cover,
+  such as The Stand News (8) and Agência Pública (6). The Hub PR has per-document
+  evidence.
+- **Borderline; dropped and flagged for review.**
+  - Freemuse ×3: the note allows republication "by non-commercial media" only.
+  - Bumaga 30003: a shorter version of the author's article for Bumaga.
+  - Hive-Mind/EJO 34820.
+  - openDemocracy 29544: "under a Creative Commons licence", version not stated.
+  - Transitions 34277: "powstał dzięki umowie partnerskiej", possibly a co-production.
+  - 32352: built on two Meta.mk texts.
+
+**Lesson** — the licence covers what the publisher created. A per-post editorial note
+is the only signal of a partner's work, so the filter has to read the note and not only
+the byline.

+
+Global Voices licenses the content it creates under CC BY 3.0. Some posts instead republish an article that a partner outlet published first, under a content-sharing agreement or with the outlet's permission. That text remains the partner's work, so the release excludes it. `src/clean_global_voices.py` finds the editorial note such posts carry in their opening or closing lines (for example "pierwotnie ukazał się na portalu PRI.org … w ramach umowy o wymianie treści"). It also excludes three posts whose note the rules miss and keeps 25 look-alike notes, each with a stated reason. Every match was checked by hand.
+
+The rule excluded 114 posts from 51 outlets. The largest groups are PRI/The World (21), The Stand News (8), Hong Kong Free Press (7), Agência Pública (6), Metamorphosis/Meta.mk (5) and 350.org (5). Three Freemuse co-commissions are excluded because their note allows republication only by non-commercial media.

+The following posts are kept:

+"""Drop Global Voices posts republished from partner outlets (slayerlabs/polish-dynaword-v2#50).
+
+Global Voices licenses "content created by Global Voices" under CC BY 3.0. Posts it republished
+from partner outlets (PRI's The World, Hong Kong Free Press, The Stand News, Meta.mk, 350.org,
+The Irrawaddy, ...) under content-sharing agreements or with permission stay the partner's work,
+so the CC BY grant does not demonstrably cover them. Each such post carries an editorial note in
+its first or last lines, e.g. "Ten artykuł ... pierwotnie ukazał się na portalu PRI.org ... i jest
+publikowany ponownie w ramach umowy o wymianie treści". `note_rules()` finds those notes.
+
+Kept on purpose: posts that GV contributors cross-posted from their own blogs, posts GV wrote for
+the ISN partnership, partner organisations writing directly for GV with no republication note,
+and photo-only permission credits ("Zdjęcie ..., użyte za pozwoleniem").
+
+The input is the Parquet and sidecar as of v0.2.5 (the Parquet is unchanged since), pinned by
+SHA-256. Restore them before a rerun:
