A resource was private with no way out but the author's own Nextcloud.
Share opens reading — open, preview, download — to one person at a time by
exact email (no account is ever listed) or to everyone signed in with one
switch; what others share appears in your library marked "Shared by …".
Writing never travels: modify, re-skin, delete and the share list stay the
author's, every write still filtered on user_id, and the read routes go
through one reader rule. Rows follow the resource and the person.

Multimodal removal
The multimodal path called nc_multimodal_search against a second hardcoded
collection whose embedding service (multimodal-embeddings:7999) was never
deployed and ENABLE_MULTIMODAL_RAG has always been false, so it only ever logged
"multimodal search skipped". Removed rather than left as dead weight:
- clinicalRetrieval: normalizeMcpMultimodalResponse, isVisualSourceQuery,
isRadiologyQuery, buildMultimodalSearchQuery, classifyAndRerankMultimodalResults,
selectMultimodalResults, visualIntent, visualMetadataScore,
shouldRejectVisualSource, allowsFrontMatterQuery, looksLikeFrontMatterPage,
looksLikeTextOnlyPage and MULTIMODAL_CANDIDATE_LIMIT (~140 lines).
- clinicalMcpClient: multimodalSearch.
- The route's visual/text slot split is gone; the whole search limit is text.
- The "[visual PDF page match]" prompt label and the "visual PDF page" source
badge are gone with it.
Adding models
Model availability could only be ticked from what the gateway advertised, so an
admin could never offer a model discovery did not list. Each list now has a text
field: a typed id joins the same checkbox list, is enabled by default, is
de-duplicated, and persists through the normal allowed_models save.

The MCP server builds a Nextcloud client per session and closes it only
when the session ends. The clinical assistant replaced its cached session
every time the ten-minute TTL lapsed but never ended the old one, so each
abandoned client held its Nextcloud connections open. The production MCP
container was holding 708 sockets in CLOSE-WAIT against a 1024 descriptor
ceiling, roughly 300 from the point where every clinical search fails.
Expired and server-rejected sessions are now deleted. Session reuse is
unchanged: a live session is still shared across calls, since closing one
still in use would force a re-initialize on every search.
