Scanned books are commonly distributed as DjVu, which the scanner only stored as a supplement.
Decode pages on the server with DjVuLibre so DjVu imports with a cover and page count, opens in
the image reader with its embedded OCR text, and can be the preferred format of an ordinary email
recipient. Migration 0113 widens the recipient format check to allow it.
Decoding runs on validated private snapshots behind a bounded, reader-first queue, and
revalidation and cached pages are answered without a decoder. Released iOS builds cannot open
DjVu, so series continuation offers it only to callers sending includeDjvu=true, and the
dashboard and notebook read file never name it. The first full scan after upgrading promotes
stored .djvu supplements to content.
Rebuilds the users roster, metadata field rules, file naming and metadata
score panels, and replaces the libraries list with an expandable ledger.
Libraries now batch their counts and last scan into one request instead of a
per-library fan-out, and surface scan history from scan_jobs on demand.
