 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)
+
+**Verdict** — kept, rows unchanged: 38,812 documents, 36,335,587 tokens, parquet
+sha256 `56f7b03483488dec8f0fa145c6d26746926175d83096e9d1931e535aa81cf161` as in v0.2.5.
+Registry, card and NOTICE now say "Sejm API data via contributor snapshot" instead of
+"Direct official Sejm API records". The text is the Hugging Face dataset
+`PiotrSty/sejm-speeches-corpus@v1.0.1` (commit `124557799608`); SlayerLab did not
+fetch it from the API.
+
+**Reason** — all 38,812 `source_url` values in the sidecar match
+`https://api.sejm.gov.pl/sejm/term{N}/videos/{date}`: one URL per sitting day, so
+the "speech-level provenance" line in the card was wrong. That is now a test in
+`src/test_sejm_api_contract.py`.
+
+### Not established
+
+- Whether the API publishes per-speech URLs, and whether the snapshot text matches
+  the live API (the audit asked for 20 rows to be spot-checked; not done here).
+- Whether the www.sejm.gov.pl terms reach API output; the API documents no licence.
+- (Fixed in a follow-up commit: the card's "Temporal novelty" paragraph named
+  `parlamint_pl` as registered; it left the registry in #54.)
+
+References: polish-dynaword-v2 #57; `rights_audit_2026-10/REVIEW.html` `#sejm_api`;
+`reports/citations/sejm_sis.md`.
+
+**Lesson** — a card line that says "speech-level" must be backed by a test on the
+sidecar, not by the template that wrote it.
