* ui: fix MCP server display name conflicts in tools lists

Tool groups were keyed by display label so two servers reporting
the same name broke the keyed each blocks and only one was visible.
Key rendering, expand state and toggles by the stable server id
instead, and suffix duplicate labels with a counter in config order.

* ui: customizable MCP server display name with autofill

Add a display name field to the MCP server form, add and edit alike.
The custom name takes precedence over the server-reported one, so two
servers reporting the same name can be told apart; clearing the field
returns to the automatic label. In the add dialog a debounced preview
handshake prefills the field with the server-reported name: a manual
edit freezes the autofill, stale responses are discarded, failures
stay silent, and an unedited prefill is not persisted so the label
keeps following the server.

* ui: fix recursive fetch passthrough in the client test setup

The original fetch was captured inside beforeEach, where it is the
previous test's spy since vi.spyOn returns the existing one, so the
default passthrough recursed on itself for any URL outside the
mocked set. Capture the real fetch once at module load.
* Start building graph - reuse deepseek32

* Enable kv cache and rotation for glm_dsa architecture

Just follow Deepseek 3.2 for now.

* Reuse prev_top_k for "shared" indexer layers

* GLM 5.2 uses LLAMA_ROPE_TYPE_NORM for the indexer.

This is transformers' `apply_rotary_pos_emb_interleave`

* Default indexer types to GLM pattern

Previous converted GGUFs like https://huggingface.co/unsloth/GLM-5.2-GGUF write indexer weights to _all_ layers, even if they are only required for "full" types. This PR relies on a new key "%s.attention.indexer.types"; if absent, it will use the default GLM 5.2 schedule as defined in https://huggingface.co/zai-org/GLM-5.2/blob/main/config.json#L26.

Note that conversion is not saving this key yet.

* Save indexer types to gguf, restore on load

* Use ggml_lightning_indexer when cparams.fused_lid

* ui: remove viewport fade in and smooth autoscroll bottom snap

fadeInView mounted every message and markdown block at opacity 0 and
relied on an IntersectionObserver to reveal it. When the observer never
fires (blocks mounted offscreen during long agentic loops) the content
stays invisible forever while still present in the DOM. Remove the
action, its orphaned isElementInViewport util and all call sites:
blocks now render visible immediately.

AutoScrollController.scrollToBottom defaulted to behavior smooth and is
invoked every 100 ms while streaming. Each tick restarts an easing
animation toward a moving scrollHeight, producing a random elastic bump
of a few pixels when the user reaches the bottom and autoscroll
reengages. Default to instant scrolling; the user facing scroll down
button keeps its smooth behavior.

* ui: skip rendering of offscreen chat messages via content-visibility

Apply content-visibility auto with contain-intrinsic-size to chat
messages so the browser skips layout and paint for messages outside
the viewport. The DOM stays complete: component state, find-in-page,
text selection, and the mutation based autoscroll are unaffected, and
browsers without support simply ignore the properties.

* ui: remove conversation switch fade

Switching conversations faded the message list out and in over 500 ms
plus a 300 ms route delay, deferring the message refresh behind two
requestAnimationFrame calls. Remove the fade, its navigation hooks and
dead state, and refresh messages directly so switching is only bound
by actual render time.

* ui: describe present behavior in comments and drop unused parameter

* ui: anchor the context gauge popup to the form with plain CSS

The stats card was portaled to body and repositioned in script on
every ancestor scroll event, trailing the page by one frame while
streaming. Render it as an absolutely positioned sibling of the input
box inside the already relative form, so nothing runs during scroll.

The card sits just above the dial, centered on it and overlapping the
textarea, from a single measurement of the dial center and top taken
when it opens; the dial and the card share the same positioning frame,
so the values stay exact while the card is open. Mouse pointers open
on hover with a grace delay to reach the card, touch pointers toggle
on tap, any press outside the card and the dial closes it, and Enter
and Space toggle from the keyboard. The card lives outside the input
box because its overflow-hidden and backdrop-filter would clip any
positioned descendant.

* ui: extract context gauge popup constants and relocate its state store

Move the placement values and the close grace delay to
lib/constants/context-gauge-popup.ts, matching the auto-scroll
constants layout, and move the popup state module from the component
folder to lib/stores where runes modules live in this codebase.

* ui: declare the context gauge popup card ref as $state
* performance harness - the empirical root

Without a virtual destructor, deleting a derived object through a

… in generation_settings (ggml-org#25830)

These two parameters were overlooked when task parameters were being JSONized
within `generation_settings` and have been added. A regression test has been
added to prevent the problem from recurring and it passes.

Fixes ggml-org#25803
The INI parser creates an implicit default section for top-level metadata.
After reserved keys such as `version` are skipped, that section can have no
model options but was still added and exposed in router mode.

Skip only the empty implicit default while preserving real default presets,
named presets, and the global `[*]` settings.

* hex-im2col: instrument and update im2col.

* move server_pipe to common

* init impl

* vendor: update subprocess.h

* add server_mcp_stdio

* stderr drain

* server_mcp_transport

* server_mcp_stdio is now framing-only, no json

* internal/mcp-stdio: integration + tests + fixes (ggml-org#26075)

* server-mcp: harden transport and wire up the tool integration

Builds on the transport/manager architecture (server_mcp_transport + server_pipe)
with the hardening and integration the draft did not yet have.

Hardening:
* Reader and stderr pumps are polled (running-aware) instead of blocking on a read
  that only ends at EOF. subprocess_terminate() SIGKILLs only the direct child, so a
  grandchild the MCP server spawned that inherited the pipe would otherwise keep the
  write end open and hang teardown (both warmup shutdown at startup and process
  shutdown). The writer is likewise non-blocking + polled.
* Windows: resolve the command through PATHEXT so "npx" (npm ships npx.cmd, never
  npx.exe) spawns, matching POSIX's PATH search; and enumerate the parent environment
  as UTF-8 (GetEnvironmentStringsW) instead of the active code page.
* server_pipe gains an opt-in max_size (default unbounded, so the router's streaming
  use is unchanged); the MCP reply queue uses it so a server that streams unsolicited
  notifications between requests cannot grow it without bound.

Integration:
* --mcp-servers-config / --mcp-servers-json flags; enabling MCP restricts default CORS
  to localhost, same as --tools.
* MCP tools are exposed through /tools (and chat-completions) as <server>_<tool>,
  skipping names that collide with a built-in or another MCP tool.
* Manager lifecycle wired into llama_server(): warmup at start, shutdown() from the
  signal handler before the HTTP server drains, blocking teardown in clean_up().
* SIGPIPE ignored so a child dying mid-write yields EPIPE rather than killing us.

* server-mcp: add MCP test suite with grandchild deadlock regression test

21 tests over the /tools endpoint: tool discovery/invocation, timeouts, crash
recovery and respawn cooldown, warmup partial failure, malformed and batched
notification+response output, tool-definition shape, and prompt shutdown during a
slow call.

The last test spawns an MCP server that leaves a grandchild inheriting its
stdout/stderr and asserts the server both starts and stops promptly. Verified it
fails (5s SIGKILL fallback on a deadlocked reader-join) when the pump is made to
ignore the running flag, and passes with the polled reader.

* fix some edge cases

* fix last_error data race

* fix response schema + docs

* server: fix MCP zombie leak and timeout-induced transport teardown

join_pumps() never reaped the child, leaking one zombie per spawn:
call subprocess_join() before subprocess_destroy().

A per-call timeout permanently closed from_server and got a healthy
transport evicted: add close_on_stop to server_pipe::read() and pass
false from send_rpc(), where should_stop is a per-request deadline
and a late reply is already skipped on id mismatch.

Also drop the unreachable disconnect cancellation in
server_mcp_tool::invoke(): support_stream is false, st is always null.

(cherry picked from commit e6de1ec)

* server: make MCP test fixtures JSON-RPC 2.0 compliant

Add the missing notification guard to mcp_malformed_server.py and
mcp_burst_server.py (the latter treated id 0 as a notification and
replied to unknown ones; its notification table is now unused).

Return -32602 instead of -32601 for unknown tools: tools/call is a
valid method, the tool name is the invalid parameter.

Also fix the test module docstring: tools are named <server>_<tool>.

…nd (ggml-org#26099)

The context gauge card starts monitoring like the dial does, because
its own processing state instance only follows the live stream while
its monitoring flag is set. It also gets back the text-sm and ring
classes the removed hover card wrapper used to inject, which restores
its layout. Routing to a conversation now lands at the bottom
instantly and keeps the pin one frame at a time until the page height
settles, since content-visibility size realizations and syntax
highlight passes grow the page without DOM mutations.

Fully rewrote minimax-m3.cpp for speed and buffer size gains:

Unified the 4-way + decode, 1 FA call per layer instead of 4, with the groups mapped onto ne[3]

Custom CPU op now emits block-level mask, expanded on GPU, which causes CPU to GPU transfer to shrinks at prefill

Decode: ~25 nodes/layer vs ~50, no per-group concats/conts

Unified selection semantics, so both regimes rank bs + local bias (position-anchored local force), which means prefill/decode can no longer disagree on selection

can_reuse on the MSA bias input. Graph reuse at decode restored (was rebuilding the full graph every token)

In-place mask adds, shrinking compute buffer ~6.8 to ~4.2 GiB at ub2048/62k

Multi-stream: MSA now runs with -np N when kv_unified=false. Decode stays batched across streams (still 1 FA call), prefill loops per stream. dense fallback only for --kv-unified + multi-seq

Measured effect on expert offload bound setup: decode 6.2(4WAY)–7.15(MSA_decode) -> 7.7~7.8 t/s, flat from 5k to 60k+. prefill around 10% faster. buffer about 20% smaller, multi-user support.

…g#26121)

* ui: detect the conversation import format from file contents

iOS resolves every accept entry to a UTI and has none for ".jsonl", so the
picker greyed out exported conversations. Drop the accept filter and pick the
parser from the file contents: ZIP magic bytes, then a first "session" record
for JSONL, otherwise the legacy JSON format.

Also remove the unused importConversations() picker and an orphan doc comment,
and cover each format with unit tests.

* ui: report what a conversation import actually wrote

The import summary echoed the selection back, so re-importing conversations
already in the database claimed success while nothing was written and only a
console warning said otherwise.

Return the imported and skipped conversations from the database layer, list the
written ones in the summary, and count the rest in a toast.

* ui: name the literals of the JSONL conversation format

Introduce SessionRecordType and SESSION_HARNESS, and reuse the existing
NEWLINE constant, so the record format lives in one place.

This also covers the writer side, which predates the import path under
review and carried the same literals: an enum stated by the reader alone
lets the two sides drift.

Values are unchanged, so an export stays byte identical.
