line_start -1 normalized to n+1, so append inserted at lines.begin() + n + 1,
one past end() -> heap-buffer-overflow in vector::_M_range_insert.
Normalize -1 to n (insert at end()), restrict -1 to append mode and reject it
for replace/delete instead of silently clobbering the last line. Parenthesize
the insert offset so empty-file append computes the position as int first,
avoiding a transient begin() - 1 on a null vector data pointer.

Use std::partial_sort to order only the requested top-n tokens instead
of the full vocabulary
logprobs sort: vocab=128000 n_top=0 iters=100
full sort: 8555.6 us/op
partial sort: 704.3 us/op

Absorb get_slot_by_id logic into get_available_slot so slot selection
is handled by a single function call. When a specific slot id is
requested, the LCP similarity check still runs to enable proper
prompt cache updates.

* server: add "X-Accel-Buffering": "no" header to streaming endpoints
This header tells Nginx (as a reverse proxy) to NOT buffer responses. (only affects streaming endpoints)
Without it, Nginx will break streaming with certain applications (notably the Pi coding harness).
* ui : add model selector storybook stories
Covers list, favorites, single-model, all status states
(loading/loaded/sleeping/failed/idle), and selection states.
* ui : improve model selector mobile UX with hover media queries
Use @media (hover:none) to show action buttons directly on touch
devices and color-code them by model status (amber=sleeping,
green=loaded, muted=idle). Status dots hidden on touch. Desktop
hover behavior unchanged.
Throw on grammar parse failure so the server returns HTTP 400
instead of silently dropping the constraint.
Add a regression test for the invalid-grammar response.
Fixes#24144
* webui: export conversations as jsonl
each session is one jsonl file, a session header line followed by one line per message
exporting multiple conversations bundles them into a zip, one jsonl file each
* webui: import jsonl and zip conversation exports
parse the new jsonl session format and zip archives on import
keep supporting the legacy json format
* UI : fix SSE transport detection and routing through CORS proxy. Assisted-by: Antigravity
* ui : replace magic strings with constants in MCP transport handling
* ui: add source toggle to mermaid and svg blocks
Add a toggle button next to copy and preview that switches a rendered
mermaid or svg block to its source code and back. The button is shared by
both block types and the rendered view stays the default.
The source view reuses the code block scroll container and the highlighted
code element captured at transform time, so it matches the app code blocks
without highlighting again.
Make tall diagrams scroll like text code blocks: safe centering keeps the
diagram centered when it fits and falls back to start alignment when it
overflows, so the top stays reachable instead of clipping above.
Keep the block header opaque and layered above the scrolled diagram, and
ignore header clicks in the zoom handler, so a button click never falls
through to the zoom dialog.
* ui: transparent diagram block header, address review from @allozaur
* spec: add spec metrics mean acceptance length and acceptance per pos
