Temporal novelty and deduplication

parliamentary ends on 2019-12-31 and registered parlamint_pl ends on 2022-12-31. Every contributed record is dated on or after 2023-01-01, so its date range overlaps neither source. Exact duplicate speech texts within the contribution are removed using SHA-1 fingerprints; this is not a claim of global cross-domain near-deduplication.

Privacy and limitations

The upstream release heuristically redacts email addresses, PESEL identifiers and unambiguous Polish telephone numbers. Public-official names and speech attribution remain. Regex redaction is not a guarantee of zero personal data. Downstream users must review applicable privacy, third-party and source terms.
