+Reuse conditions common to these instruments: acknowledge the source, do not distort the original meaning, and
+the institutions accept no liability for the consequences of reuse. ParlIR **modifies** the texts (header
+stripping, identifier masking, text extraction from XHTML/DOCX/XML); `raw_text` keeps the header-stripped,
+unmasked body.

+## Personal data
+
+Author names are those of Members of the European Parliament acting in their official capacity, as published by
+the Parliament. They are kept as metadata and removed from the canonical retrieval text where they appear in
+headers and co-signatory lines; residual mentions remain (e.g. 12 train queries with a "Question supported by …"
+list, and MEPs or other public figures named in question/answer content). `subject`, `header` and `raw_text` are
+unmasked. See docs/datasheet.md "Known issues in v1.0". A GDPR/legal-basis statement and a takedown contact are
+human-author decisions (docs/submission-checklist.md).
