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.

Reverts 126d7928 and 2d292d12 in full. The markdown normaliser and the trailing
emphasis and dollar handling return to exactly the state tagged
pre-citation-fixes-20260828, which has been rendering acceptably in use.
The one change kept is mermaid. DOMPurify 3.1.6 strips an attribute whose value
contains "-->", and every mermaid flowchart contains one, so the sanitiser
removed data-mermaid and querySelectorAll('[data-mermaid]') never matched: the
diagram sat on "Rendering graph..." forever. Reproduced against the exact pinned
build from cdnjs; sequence diagrams using "->>" were unaffected, which is why
only flowcharts failed.
The diagram source is now percent-encoded into the attribute and decoded when
read, so no arrow ever appears in an attribute value. Nothing about the
sanitiser configuration changes and no markup is newly allowed. The reader
tolerates an unencoded value, so anything already in flight still renders.

The earlier fix corrected two of the repair rules and left the rest with the same
flaw, and the punctuation boundary it introduced let the table case back in. A
review found the remainder.
Every repair rule inserted newlines with no idea whether it was inside a markdown
table row. A dose row such as "| Dexamethasone | 0.6 mg/kg PO (max 16 mg) - single
dose | 1 |" was split mid-row, which drops that row's citation and every row
below it out of the table. A "#" column destroyed the table outright. The rules
now skip table rows, dividers and headers entirely.
Ranges were still split in three other places: in a heading, so "### Dexamethasone
0.15 - 0.6 mg/kg" rendered as a heading reading "Dexamethasone 0.15"; after a
citation; and beside a hash, where "Room # 4" became a heading. A hyphen now
starts a list item only when a number does not follow, and a run-together heading
is recognised by the capital letter after the hashes rather than by position.
Adjacent citation merging could also cross a paragraph break, turning "[1]\n\n[2]
Vancomycin only if MRSA" into "[1, 2]Vancomycin only if MRSA" -- joining two
paragraphs and moving a citation onto a claim it never supported. Merging is now
limited to citations on the same line.

Three rendering defects in the clinical assistant, all confirmed by running the
code rather than reading it.
A spaced hyphen anywhere in a sentence was rewritten as a list item, so every
numeric range written that way was split in two:
"Give dexamethasone 0.15 - 0.6 mg/kg orally."
-> "Give dexamethasone 0.15\n- 0.6 mg/kg orally."
which renders as a truncated sentence followed by a bullet, and a dose range
therefore reads as a different dose. The same applied to SpO2 targets, pH ranges
and age ranges. A hyphen now starts a list item only at the beginning of a line
or after sentence punctuation, which still catches the case the rule was written
for.
An answer ending in a bold phrase lost its closing marker, because trailing
emphasis was stripped unconditionally and the strip ran twice. Only an unpaired
marker is removed now.
Inline maths swallowed dollar amounts: "Costs $5 to $10 per dose" rendered the
text between the signs as an equation and dropped both signs. A $...$ span is
now treated as maths only when it contains something mathematical, so subscripts
and fractions still render.
Citation handling is unchanged and covered by the same tests: clusters still
merge and sort, unknown source numbers stay literal, links still resolve by index,
and bare numbers in a table's Source column still become bracketed tokens.
The state before these fixes is tagged pre-citation-fixes-20260828.
