Ask HealthLog whether a document is already held before downloading it
from Paperless-ngx or Papra, and send the source key in the query string.
Pin Paperless API version 9 (Paperless-ngx 2.16 and later), apply --since
locally for Paperless too, fall back to the file name for a blank title,
stop with a clear message when the HealthLog address redirects, and say
only that storage is full when the figures are withheld. The guide names
the minimum versions and the shared OTHER namespace.
