The owner fetched the 167-page French C956 operator manual from
karosa-club; it now sits in the local doc folder (128 MB scan,
checksummed, page count verified) and moves from the failure table to
the retrieved list in the index.
Ten verified PDFs now live locally (gitignored, copyright): EuroRider
and Voith manuals, three Axer brochures, and the official equipment
datasheets. The index carries SHA-256 sums and source URLs for
rebuilding the folder, plus the documented failures: the nine
karosa-club documents sit behind a login or 4.5 EUR paywall despite
their free label, and the Pylontech site defeats plain curl.
