dziennik_ustaw has carried license_spdx: CC0-1.0 since the first commit (cfe406c), with no stated basis. The acts are outside copyright under art. 4 pr. aut., and nobody dedicated them under CC0. The six other official-record sources already use LicenseRef-Polish-Official-Documents; parliamentary switched in #101.

• src/sources.py: license_spdx CC0-1.0 -> LicenseRef-Polish-Official-Documents. The human-readable license ("public-domain (official documents)") and the traceable text are unchanged.
• PAPER.md: the source table said "public-domain (CC0)". It now says "public-domain (official documents)".
• src/verify_paper_claims.py: docstring only. norm_license said SPDX spells official documents as CC0-1.0. The regex is unchanged; OFFICIAL already maps the new value to the same family.

No data, datasheet or stats change. Test results are identical before and after (LFS-skipped worktree: same 93 failed / 18 errors set, all needing parquets). verify_paper_claims.py against the v0.2.6 paper draft (slayerlabs/polish-dynaword-v2#93) still passes the dziennik_ustaw licence row.
