An update whose cross-reference section has no /Prev (ISO 32000-2 §7.5.6, §7.5.8.2) cuts the earlier revisions, and the page tree with them, off the chain. The signed PDFBOX-2720 and PDFBOX-2942 files have this shape: the document model found no page tree and the renderer showed 2 blank pages found by scanning for page dictionaries. When the chain reaches only the newest section, the file holds another startxref and the catalog's /Pages can't be read, both readers now rebuild the table from the file's objects, as for a damaged file: - cos: the existing reconstruction (newest in-file definition wins), a repair-log line saying why, and `Document::rebuilt_unlinked_update`. - hayro-syntax (44): `root_xref` repairs the table before the page tree is read; `Pdf::rebuilt_unlinked_update` says so. - render: an open warning, and the lazy structure reader accepts such a rebuilt file, so links, fields and bookmarks are read too. A save rewrites the file in full (main's rule for reconstructed files). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Pq7HyCHD1R3rywQBPCHXZA
