* Classify line ends by alignment clusters and canonicalize definition listsMatthias Andreas Benkard2026-07-197-55/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The percentile-based right-margin estimate from the previous commit misclassified two real-world layouts: at the column switch of the two-column old-BGBl format a window contains both column margins, so the 90th percentile returned the right column's margin and marked every left-column soft wrap as deliberate (vetoing hyphen mending, IfSG 2020: "Impf- surveillance"); and series of equally wide centered "Artikel N" headings in draft bills formed the top of their window's distribution, so they counted as full-width and were reflowed into the following line, breaking teileInArtikel's line anchor (ProdHaftG RegE). Classify against alignment clusters instead: a line end is soft when at least five window lines end within 4 pt of it (the justified block's own margin), hard when such a cluster runs at least 10 pt above it, unclassified otherwise. Structure anchors ("Artikel 2", "§ 19", bare Gliederung labels) are always exempt from reflow since equal-width heading series still form sham clusters. Also flush the pending line end-X at page ends — without it, the first line of the next page inherited the previous page's footer geometry and was misclassified (UWG: "Artikel 2" swallowed the closing provisions). Markerless joins additionally never cross into a following enumeration marker line ("...vorgesehen und" + "d) die Überwachung" no longer glues to "undd)"), a text-level veto that also works without geometry. On the base-law side, ContentFlattener now separates sibling <LA> elements within a <DD> — the short-label/definition pairs of the UWG Anhang and § 2 IfSG were previously glued without any separator ("Irreführung über Unternehmereigenschaftdie unwahre Angabe...") in both synopsis columns. The continuation line is indented two spaces deeper than its enumeration line so StellenAufloeser.zeilenBlock keeps it inside the unit's block ("Anhang Nummer 31 Buchstabe b"). BefehlAnwender writes the same canonical shape when inserting or recasting quoted units (rueckeZitatEin), so XML-derived and PDF-derived items agree: " 2a. Stichwort" + " Definitionstext". Verified by mvnw verify (179 tests, 7 new) and a before/after sweep of all 21 sample law/amendment combinations: applied/manual counts are unchanged throughout (UWG 19/0, GEG-BGBl 66/53, GModG-RegE 77/20, IfSG-0645 42/24, ...), no marker characters leak into the HTML output.

* Classify line breaks geometrically via PDFBox coordinates and support list ↵Matthias Andreas Benkard2026-07-174-48/+317
| | | | | | | | | | | | | | | | | | | | | | | indentation Replaces the heuristic character-count full-width check with real geometric layout analysis. FontgroessenFilter collects the right-edge X coordinate of the text runs on each page and classifies line endings against the local 90th percentile of page margins (using a 20-line sliding window) into soft, hard, or unclassified breaks. TextBereiniger uses this classification to reflow only soft line wraps (WEICH) and keep deliberate ones (HART or UNBEKANNT). Also aligns quote normalization and GII-XML flattening to indent continuation lines in lists (e.g., hanging definitions in UWG Anhang): - BefehlAnwender.normalisiereZitatText applies to single-unit Neufassung and indents continuation lines deeper (4 spaces) than list items (2 spaces). - ContentFlattener generates the same structure for sibling <LA> elements inside <DD>. This ensures the paragraph parser correctly groups these lines as child lines. Change-Id: I1fd7039d4933a273cc2dc55f958d34b439e2302c
* Fix markerless line-break join gluing whole words without a spaceMatthias Andreas Benkard2026-07-174-3/+79
| | | | | | | | | | | | | | | | | | | | | | | | TextBereiniger.verbindeUmbrueche assumed any letter-ending, no-trailing-space line followed by a lowercase continuation was a hyphen-less mid-word split (PDF extraction artifact) and joined it with zero separator. That assumption breaks for deliberate word-boundary breaks, e.g. the short-label/hanging- indent definition format in the UWG Anhang ("...Nachhaltigkeitssiegels" + "das Anbringen..."), producing glued words in the rendered synopsis. Gate the markerless join on the candidate line reaching a locally-typical "full column width" (90th percentile in a ±20-line window), since automatic wraps always land near the column edge while deliberate breaks don't. The window is local rather than document-wide because some source PDFs mix column widths within one document (narrower Regelungstext vs. wider Begründung), which a global statistic would otherwise penalize. Also route the single-unit Neufassung fallback through the existing normalisiereZitatText normalization, matching its sibling code paths, so that internal line breaks now more often preserved by the fix above don't leak into the HTML output as spurious line breaks instead.

* Model and apply structural (Teil/Abschnitt) and TOC commandsMatthias Andreas Benkard2026-07-1314-15/+387
| | | | | | | | | | | | | | | | | | | | | | | | Introduce the Gliederungsbaum into the model and support the structural command families that were the bulk of the remaining unknowns: - Gliederung gains a kennzahl; Gesetz carries the ordered list of Gliederungseinheiten, which the loader now collects. - New Stelle components Gliederungseinheit (Teil/Abschnitt/Unterabschnitt/ Anlage/…) and Absatzbezeichnung; StellenParser parses these plus "Überschrift von <Gliederung>" and drops "Satzteil/Angabe vor Nummer N" chapeau qualifiers. - Gliederungs-Überschrift Neufassung/Streichung apply to the tree and render as a "Geänderte Gliederungs-Überschriften" diff section; Absatzbezeichnung-Streichung removes an Absatz number; Inhaltsübersicht "Angabe(n) zu …" commands are recognized (applied via the existing TOC path). Reuses Neufassung/Aufhebung with structural Stellen rather than adding new command types. Final UnbekannterBefehl counts: GEG 50->5, IfSG 11->3, AGG 2->0 (§ 1 Alters->Lebensalters now applies), UWG 2->0.

* Support range, renumbering, and punctuation commandsMatthias Andreas Benkard2026-07-136-26/+387
| | | | | | | | | | | | | | | | | | | | | | | | | Extend the parser and applier for several command families that were falling back to UnbekannterBefehl: - Range/coordinated Aufhebung ("Die Nummern 1 bis 3 werden aufgehoben.", "Die Absätze 4 und 5 werden aufgehoben.") via bis-range expansion in StellenParser.parseMehrfach and ausStellen. - Range renumbering without "zu den" and for Nummern/Buchstaben ("Die bisherigen Nummern 4 bis 6 werden die Nummern 8 bis 10."); single renumbering now also covers Nummer/Buchstabe and "Die bisherige". - §-range Neufassung ("Die §§ 52 bis 56 werden wie folgt gefasst: …"), splitting the quoted block at "§ N" boundaries. - "Der Wortlaut wird Absatz N." — a new WortlautZuAbsatz command that numbers the previously unnumbered body. - Word-to-punctuation replacement ("… das Wort „oder" am Ende durch ein Komma ersetzt") and comma+words insert/replace variants. StellenParser gains plural component words (Absätze/Sätze/Nummern/ Buchstaben) and bis-range expansion. Cuts UnbekannterBefehl further: GEG 36->21, IfSG 7->3.

* Recognize compound and multi-pair amendment commandsMatthias Andreas Benkard2026-07-134-28/+289
| | | | | | | | | | | | | | | | | | | | | | Split BefehlErkenner into a single-command pass and a fallback that composes Sammelbefehle from commands chained with "und"/", wird": - Multi-pair replacement ("… A durch B und C durch D ersetzt") emits one Ersetzung per pair, crossed with the (possibly coordinated) Stelle. - Verbund splitter probes each "und"/", wird" boundary; when both halves parse — trying the right clause as-is, capitalized, or with the left clause's locative prefix — it folds them into one Sammelbefehl. The single pass no longer short-circuits when a pattern matches but its Stelle is unparseable, so the fallback still gets a chance. Add "ein Komma eingefügt" and anchor-first insertion patterns the splitter needs, and let StellenParser.parseMehrfach inherit the component type for bare-number continuations ("Absatz 1 und 5"). Cuts UnbekannterBefehl counts: GEG 50->36, IfSG 11->7, AGG/UWG 2->1. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Change-Id: I8f76edd0c9ed6cf68c10c50f535a8182e13e378e
* Support multi-target "jeweils" commands and range renumberingMatthias Andreas Benkard2026-07-138-15/+396
| | | | | | | | | | | | Add a Sammelbefehl command that applies one operation to several "und"/"sowie"/comma-coordinated Stellen sharing a common prefix, and resolve "Die bisherigen Absätze X bis Y werden zu den Absätzen X' bis Y'" into descending single renumberings. Parsing gains StellenParser.parseMehrfach; the applier folds sub-commands into one log entry.

* Add AGG, BayJG, GEG, ProdHaftG, and UWG sample data.Matthias Andreas Benkard2026-07-1342-0/+29415
| | | | | | | | | | | | | | | | | | | | Five new datasets with provenance in SOURCES files: * UWG: 3. UWGAendG (BGBl. 2026 I Nr. 43) in the new digital BGBl format, plus drafts. * GEG: the 2023 "Heizungsgesetz" (BGBl. 2023 I Nr. 280, new format) and the pending GModG 2026 drafts. * AGG: 2. AGGAendG drafts (RefE/RegE/BT-Drs 21/6178) -- the base XML predates the bill, so this dataset produces real diffs -- and the official BMJV synopsis as ground truth. * ProdHaftG: product-liability modernization drafts (Artikel 1 is a replacement act, Artikel 2 amends the old law), with official synopsis. * BayJG: Bavarian hunting-law amendment (GVBl. 2026 S. 113) -- state law is not yet supported by the tool; kept for future work.

* Support the digital BGBl format and bill drafts as inputs.Matthias Andreas Benkard2026-07-1313-74/+788
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Implement the synopsis pipeline for amendment acts.Matthias Andreas Benkard2026-07-1324-35/+3187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the full vertical slice from input files to a two-column HTML synopsis: * gesetz, gesetz.gii: immutable law model (Gesetz/Norm/Absatz) and an offline loader for the gii-norm XML format of gesetze-im-internet.de, flattening DL enumerations, tables, and pre blocks. * aenderung: amendment command model as a sealed interface with records (Ersetzung, Neufassung, Einfuegung, Anfuegung, Aufhebung, Streichung, Umnummerierung), including UnbekannterBefehl as the mandatory fallback -- unrecognized commands are reported, never dropped. * aenderung.parse: text extraction (PDFBox in content-stream order for two-column BGBl PDFs, plain text as escape hatch), BGBl header and hyphenation cleanup, quote extraction with placeholder substitution (quoted blocks cannot confuse the command regexes; unbalanced quotes -- which occur in real BGBl documents -- become warnings), outline scanning with successor-validated markers (1., a), aa), aa1)), and the command recognizer with context-frame stacking. * anwendung: sequential command application with a per-command protocol (ANGEWANDT / MANUELL_PRUEFEN plus reason), scope resolution down to sentence/enumeration ranges via a German sentence splitter. * synopse: norm pairing, word-level diff via java-diff-utils, and a self-contained HTML renderer with a Manuell-pruefen section. The CLI gains -o/--output, --vollstaendig, --artikel, --extract-only, and hidden debug flags (--dump-gesetz, --dump-befehle). On the IfSG sample (Drittes Bevoelkerungsschutzgesetz, BGBl. I 2020 S. 2397), 63 of 75 commands in Artikel 1 and 2 parse into typed commands; the remainder are ranges and compound commands that are deliberately out of scope for v1.
