A certificate of incapacity for work (in Germany the
Arbeitsunfähigkeitsbescheinigung) is now its own document kind,
SICK_NOTE, instead of Other. The enum value rides migration 0370.
Uploads, edits, the kind filter, bulk edits, the import script and the
backup format accept it; the vault files it with a thermometer glyph
between prescriptions and referrals; the filing suggestion can propose
it and names the words a sick note carries. The extraction's own kind
field keeps its three values.
URL-backed facets (q / kind / episode / year) parse and serialise through
one pure helper pair so deep links round-trip byte-stable; the API search
builder pins the timeline sort. Month bucketing + row chunking feed the
virtualized grid as a flat item list. The upload-response parser owns the
duplicate contract: HTTP 200 with envelope-level meta.duplicate returns
the existing row, every 413/415 reason maps to a translated-copy class,
and proxy-stripped bodies fall back to the HTTP status. Query keys move
to the vault filter shape and gain the usage read.
