mtlcl410andClaude Opus 5.5 6847b1ea7e M1: a file whose last update has no /Prev opens with all its pages and a repair note (core.repair-broken-files) ...

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).
