A folder that Bindery made hid a missing volume mount. The books went
to a folder inside the container, and CWA never saw them. A missing
folder is now an error in the log at the start, and each upload fails
with a message that names the mount.
A download built the book again each time. It now sends the kept build,
and builds only if the book changed after it. Stop tracking deletes the
built book. A cancelled import deletes its uploaded file, and the start
deletes the uploads that no job needs.
A key of the chapters, rules and metadata of a story tells if its book
changed. A check without a change no longer builds the book again, also
for a book that waits for an upload. A held book goes out without a new
build. The Rebuild button still builds and sends in each case.
