Fetch one RIS document’s full text or its rendition URLs, with explicit binding status and the amtssigniert authentic PDF surfaced wherever it exists. Address the document exactly one of two ways: document_number plus application (both copied verbatim from a ris_search_* or ris_lookup_citation result), or a document_url from a result’s content_urls — or, for a draft’s companion documents (Erläuterungen, Textgegenüberstellung, WFA, cover letter, annexes), a ris_search_drafts record’s materials[].url, which is the only route to them. format: markdown (default — the HTML rendition converted to markdown, or the PDF’s extracted text where a PDF is the only rendition), html (raw HTML rendition), xml (the RIS Nutzdaten XML), or urls_only (no fetch — every rendition URL, including the Authentisch PDF). Format availability varies by application and the tool degrades explicitly, never silently: consolidated law, gazettes, case law, drafts, and most sectoral collections carry full text; district and municipal promulgations and court rules (Bvb, GrA, KmGer) publish only the signed authentic PDF; party-transparency decisions and council minutes (Upts, Mrp) are PDF-only; the 1848–1940 imperial gazettes (BgblAlt) are metadata-only. Where a PDF is the only rendition — those PDF-only and authentic-PDF-only applications, and a draft companion filed with no html twin — markdown returns the text extracted from it (text_source: pdf, a "--- Page N of M ---" line before each page, a notice naming the PDF); for an authentic application the signed PDF stays the binding artifact to cite. html and xml there, every format on BgblAlt, and a PDF whose text cannot be extracted (a scan with no text layer — no OCR is performed — or an oversized, unreadable, or unreachable file) return a format_unavailable notice with the usable URL, not an error. Every result carries binding_status; only authentic (amtssigniert) publications are legally binding. This tool returns content, not fresh metadata — the metadata rides the search/lookup step that produced the document number. When the markdown text overflows the 40,000-byte budget the tool returns an outline (kind: outline) instead of truncating: the document’s §/Artikel/Anlage sections where it carries at least two such headings, otherwise contiguous byte windows named Part 1 of N … Part N of N covering the whole text and listed in document order. Re-call with sections:[…] naming outline entries to retrieve just those; a name matching no entry returns the outline again with a notice rather than the whole document. Windows are cut at line breaks, not at sentence or § boundaries, so one can open mid-sentence — read them in order and pull the neighbour when a passage straddles a cut. Raw html and xml renditions are never sliced: at or under the 40,000-byte budget they return whole; over it the result is kind: link — no text, truncated: true, the full byte_size, and content_urls, whose html or xml entry fetches the whole artifact in one GET. Every HTML rendition opens with a 40–70 KB stylesheet, so html practically always returns kind: link — read with markdown, parse with xml, and fetch content_urls.html for the authentic markup. Markdown drops the screen-reader expansions RIS ships alongside each abbreviated citation, keeping the visible citation form, and prints each Absatz, Ziffer, and litera under its own statutory label — (1a), 2., b) — with no generated list number in front; raw html/xml renditions are returned exactly as published.
