Support the digital BGBl format and bill drafts as inputs.
The Bundesgesetzblatt has been published digitally via recht.bund.de
since 2023 in a new single-column layout, and pending amendment acts
are only available as Referenten-/Regierungsentwuerfe or Bundestag
printed papers. Both now work as patch inputs:
* PDF extraction filters out small print by font size (two-pass
PDFTextStripper): in the new BGBl format, footnote blocks and
superscript footnote markers would otherwise land in the middle of
the statutory text, even inside quoted passages.
* TextBereiniger recognizes the new page headers (BGBl "Seite N von
M", draft page markers " - N - ", Bundestag printed-paper headers)
and joins markerless end-of-line hyphenation (BT-Drs PDFs break
words without a hyphen character; regular wraps carry a trailing
space, so its absence is the signal -- gated on the source using
the trailing-space convention at all, protecting hand-written
plain-text inputs). BMJV draft templates draw the hanging opening
quote after the paragraph marker ("(1) „" / "§ 19„"); this
inversion is repaired.
* Drafts embed the statutory text between a cover sheet and a
Begruendung section; article scanning now stops at the Begruendung
heading. Articles without numbered items (single-command articles
like ProdHaftG-RegE Artikel 2) are parsed from the preamble rest.
* Target-law matching is declension-tolerant ("Das Allgemeine
Gleichbehandlungsgesetz" matches "Allgemeines
Gleichbehandlungsgesetz") via rough word-stem comparison.
* New command form StrukturErsetzung ("§ 2 Absatz 2 wird durch die
folgenden Absätze 2 und 3 ersetzt"); "durch die folgende
Überschrift/den folgenden § N ersetzt" map to Neufassung; plural
insertions ("die folgenden Absätze 6 und 7"), triple-letter outline
markers (aaa), the compound punctuation replacement ("durch ein
Komma und die Wörter ... ersetzt"), and Inhaltsuebersicht-Angaben
inside a context frame are recognized.
End-to-end smoke tests cover the four new datasets: UWG (new BGBl
format, footnote-filter assertion), GEG 2023 ("Heizungsgesetz",
121 commands), AGG (BT-Drs draft against an unconsolidated base --
the first dataset with real diffs, spot-checked against the official
BMJV synopsis), and ProdHaftG (draft whose Artikel 1 is a replacement
law and only Artikel 2 amends the base).
