* llama : build the k-pool sparse selection independently of the kq_mask shape
qwen4exp (QSA) and glm5-next pick cache cells by index and no longer read the kq_mask values, but they still shaped the selection like the dense kq_mask. Build the selection as [n_kv, n_tokens] over the cache cells instead, and split it into the streams of the K view right before the attention.
This lets the dense mask change its layout (e.g. per-sequence row lists) without touching the sparse layers.

* vulkan: allow dim 3 broadcast in MUL_MAT
supports_op rejected every MUL_MAT whose src0 and src1 differ in ne3,
although mul_mm, mul_mmq and mul_mat_vec already broadcast src0 over
dim 3 through broadcast3. Such a matmul then ran on the CPU with a
copy of the weight, and the split layout changed with the number of
streams in the ubatch.
Keep the strict check for MUL_MAT_ID only, and route the broadcast
cases away from mul_mat_vec_nc, the one path that requires equal ne3.
* tests : harden MUL_MAT with permuted dim 3 broadcast cases
Harden the MUL_MAT coverage with a weight broadcast over dim 3 against
a permuted per-stream activation, the shape of an MLA output
projection with a non unified KV cache, for a single token, several
heads and several tokens per stream.
The expand button wrapping the system message card defaulted to
inline-block. WebKit takes an inline-block's baseline from its last
line even when that line is clipped by the card's max-height, so the
row grew to the height of the whole prompt and left a large empty gap
below the card. Make the button a block so the row matches the card.

A measure child runs no_alloc, so the free memory it reports does not
include its estimate: subtracting self there erased the memory held by
other processes, down to zero with --fit on, and the next load could
overshoot the margin. Subtract self only for instance reports.
A queued load only checked --models-max before claiming, so when the
memory margin blocked it behind a busy model, load() threw and the
waiter retried in a tight loop. Refuse the claim while the limits are
exceeded and no idle model can be unloaded, so the waiter sleeps on
the condition variable until one goes idle.

* model : add MiniCPM-OCR-Jev support
The model is a Qwen3.5-VL trunk with a value head read at the last token: it
scores an OCR text against an image rendered from it, it does not generate.
Add the openbmb-minicpm-ocr-jev decision type, served by POST /v1/systemone.
The class scores are the pooled output of the sequence, read with last pooling,
so the conversion turns score.weight into cls.output and sets
embedding_length_out. The checkpoint has no LM head, so text generation is
rejected instead of using the output weights duplicated from the token
embeddings.
The task is fixed, so its prompt is entirely in the systemone template, the
same way h2o-lightning keeps its default there. The processor of the checkpoint
allows up to 16384 merged tokens per image, more than the Qwen-VL default of
mtmd, so the mmproj keeps the image budget of the preprocessor config. The
checkpoint declares MiniCPMOCRForSequenceClassification in its config.json, as
other models do.

* tests : fix multi-seq split replay against trained models
The rollback snapshot is captured by the graph that decoded the rolled-back
tail, while the reference context decodes the same prefix with different
batch shapes. The two states differ in the last bits and trained models
amplify the difference with every replayed token. Compare only the first
replayed token of each seq, then restore the rollback state into the
reference context before the seq-1-only tail.

including the cell layout, and the tail logits must match bit-exact. Also

* ui: add conversation compaction
Add a compaction action that asks the model to summarize the
conversation so far and stores the summary in a new compaction node
appended to the branch. Later requests slice the branch at the last
compaction node, keeping the system prefix and continuing from the
summary instead of the full history, which frees up context while the
complete history stays visible and navigable in the UI.
The slice is applied once at the request funnel, covering the plain
send, the agentic flow and the KV cache pre-encode, plus the continue
path that bypasses it. The summary request is a one-shot outside the
SSE replay machinery, streamed live into the node with a full rollback
on abort, error or empty result.
The action is exposed as a /compact slash command and a Compact button
in the context gauge popup, with an overridable summarization prompt
in the settings.
* ui: pre-fill KV cache and refresh context gauge after compaction
Once the summary is stored, pre-encode the compacted branch and stamp
the returned prompt timings on the compaction node: re-encoding the
reduced prefix is part of the compaction itself, so the server KV
cache and the context gauge reflect the summary right away.
The summary stream is registered under a prefixed identity
(compact::convId), so the visibility kick and byte-offset resume
protect it through tab switches while the reload probe never
reattaches it as a chat turn. The stamped node becomes the shared
context truth for the gauge and the processing state restore, and the
stale live state that kept the gauge full is cleared.
* chore: format
* ui: allow a dedicated model for conversation compaction
An opt-in setting reveals a model selector whose options come from the
live router model list. The chosen model writes the summary and is
loaded on demand when it is not resident, while the default path keeps
resolving to the conversation's own model.
* ui: align the compaction model field with project conventions
* ui: fix the model option helpers import path
The compaction model selector pulls filterModelOptions and
groupModelOptions from the models component folder, where they no
longer live, so the build fails to resolve the module. Point the
import at the navigation folder, which now owns them.
Missed during the rebase: the helpers moved in a commit that does
not touch any compaction file, so nothing conflicted.
* ui: import the model option helpers from models/utils
* ui: follow the moved models selector in the compaction model field
The models manager moved ModelsSelectorList under ModelsSelector and
the model option helpers to /utils, where groupModelOptions takes
the options alone. Drop the stale copy the rebase kept and read the
helpers from their new home.
* ui: drop the dedicated compaction model
A summary written by another model loses the prefix the conversation
model cached, so the whole history is prefilled again, and the model
then resumes from text it did not write. The conversation model
always writes its own summary.
* ui: keep the last steps of a compacted conversation
A compaction now folds the steps the model reads but the last ones,
a step being a user message or an assistant message with its tool
results, and stores how many it kept on the compaction node. The
model then reads the system prefix, the summary, the kept steps and
what follows.
The summary request is the request the chat sends, with its options,
tools and message shaping, cut before the preserved steps: the server
reuses the prefix it cached and only the instruction is new. The
number of preserved steps is a setting, 10 by default.
* ui: run every compaction summary through one path
Three callers needed the same thing - the automatic pre-encode pass, the
action in the context gauge, and re-running a summary from the block - and
each of them had grown its own copy of the request, the streaming and the
storing.
There is one path now: a summarization owns a node, streams into it, and
reports itself through a ledger the rest of the app reads (`isCompacting`,
which node belongs to which conversation). Re-running a summary is the same
call on an existing node, so the two entry points cannot drift apart again.
* ui: give the compaction row its own summary UI
The summary was a line of text in a tool-call-shaped collapsible, which is
how a compaction reads as a side note rather than as the thing the rest of
the conversation now stands on.
The row is its own block: a divider that names the boundary, and the summary
inside it with the model that wrote it, its statistics, and the same actions
an assistant turn has - copy, edit, fork, regenerate and delete all apply to
the summary, and it collapses to the divider once a summary is in, because
the shrunk context is the headline and the prose is the detail.
The divider is a variant of the shared collapsible block, which also needed
the toggle and the title split into snippets so a caller can lay them out
without copying the markup. The action icons no longer take a role: they
render what a message offers, and a compaction offers the same as any other
stored message.
* ui: report compaction progress on the row
The row owns the run, so the row says how it is going: the prompt progress
in the header while the context is being read, the phase once the summary
starts streaming, and the token count once it is in. Before the first
summary token there is nothing to collapse, so the header stands on its own
instead of offering an empty block.
* ui: keep the summarized turns quiet while a compaction runs
The turns being summarized used to keep their own "Processing..." indicator
and live reading stats while the summary streamed, so the conversation said
the same thing twice in two places. The row reports the run, so the turns it
replaces stay silent until it is done.
* ui: hand the compact action to the context gauge
Compacting is a decision about the context, so the action belongs with the
numbers that show the context filling up rather than inside the form: it sits
at the bottom of both the hover card and the drawer, under the breakdown it
acts on, quiet enough to stay a footnote and disabled - with the row's own
spinner - while a summary is already running.
* ui: follow the bottom, otherwise leave the view alone
The screen scrolled itself with a controller of observers, intervals,
direction heuristics and landing timers, and still managed to move the view
while the reader was reading: any mutation that grew the branch was treated
as a reason to keep following.
The page is the scroller, so it follows when the reader sits at the bottom,
and stays where it is otherwise. A resize observer plus native scroll
anchoring does the rest, and `pointerdown` buys the reader a moment of grace
to be caught mid-drag.
* ui: expand collapsible bodies with a height transition
Expanding a block snapped it open: the body was mounted the moment `open`
flipped, so a tall block moved the conversation around it in one frame.
The body now goes through the same region the models table uses. The height
interpolates and the visibility follows it, so a body is unmounted once the
collapse has finished rather than the moment it starts - a closed block
still costs nothing while tokens stream past it.
* ui: open a compaction summary at the top of the screen
Toggling a summary left the reader wherever they were, so a conversation that
had just compacted showed the divider at the bottom of the screen and read
down from there.
A toggle now scrolls the page once and lands the divider a breath under the
tabs, both ways: the summary is read from its beginning, and closing it returns
to the same boundary instead of wherever the page happens to come to rest. The
scroll waits for the body to reach its height, because before that the page is
too short to scroll the divider up there and the call would clamp.
That wait is the shared collapse duration rather than a transition event: an
engine without `interpolate-size` animates the region's grid row instead of its
height, so a listener on `height` would never fire there and the page would not
move at all.
* ui: spin the compaction icon while the summary runs
The divider reported the phase in its title while the icon still showed a
finished block, so a run in progress and a summary that had landed looked the
same in the one place the eye reads first. The icon spins while the summary is
running and folds back once it is in.
* ui: let the compaction summary speak without the reasoning trimmings
The summary is the thing the conversation now stands on, not a note beside
it, and the conversation model always writes it, so the body drops the
reasoning block's rule and indent (`flushBody` keeps them for the blocks
that borrow them) and the model selector under the summary is gone - there
is nothing left to swap.
* ui: drop the model override from the compaction path
The summary row no longer offers a model selector, so nothing hands
regenerateCompaction a model anymore. Remove the parameter from the
whole path, with the on-demand load of another model it carried: the
summary always comes from the model the request funnel resolves.
* ui: let the compaction summary think as the chat does
The summary request forced thinking off, overriding the reasoning
effort the user chose. The summary is the text the conversation
resumes from, the task where reasoning helps the most, so the request
now carries the very options of the chat.
* ui: pre-encode the compacted branch as the next turn reads it
The post-compaction pre-encode sent the branch without tools, while
the tools render ahead of the messages, so it warmed a prefix the next
turn never reads and that turn prefilled the whole compacted context
again. The pre-encode now sends the tools, message shaping and
reasoning handling of the chat, so the next turn only prefills its new
message.
* ui: pre-encode the branch the next turn actually reads
The per-turn pre-encode sent the messages of the request plus one
assistant message holding the streamed text, without tools. With
tools on, it replaced the slot the next turn extends with a prefix
nobody reads again, and after an agentic turn its history did not
match the stored calls and results. Without agentic, it never ran.
Both pre-encodes now read the stored branch up to its leaf, cut at the
last compaction, and send it with the tools, message shaping and
reasoning handling of the chat. The plain completion path triggers it
too.
* ui: refuse a compaction summary the output limit cut
The stream handler read every chunk but dropped the finish reason, so
a summary cut by max_tokens folded the conversation into half a text.
The handlers now hand the finish reason to onComplete, and a summary
that ends on length rolls the compaction back with an error.
The summary was framed through a replacement string, so $& or 32560 in
it changed the text the model read; it is framed as written now.
* ui: wait for the collapse transition in the tool call tests
The collapsible body now unmounts once its collapse animation ends rather
than as soon as the block closes, so the "folds back" assertions ran before
the body was gone. Wait out COLLAPSIBLE_TRANSITION_MS first.

Every dst row comes from src0 or src1, or for dim 0 from the row of
src0 followed by the row of src1, so a single kernel covers every
type: a dense source row is one memcpy, quantized types included,
and a strided source is copied element by element with the element
size known at compile time.
Rows are split across threads instead of i2 alone, which is often 1,
and are copied in tiles of 32: for a transposed source the elements
are walked in the outer loop, so the rows of a tile read neighboring
addresses instead of jumping a full row stride per element.
Add transposed b cases to test_concat, the layout of the delta-net
conv input, and a perf case for it.

Fall back to per-row uploads for noncontiguous device rows,

* tests: pin model resolution on real repo listings
Extend test-model-resolution with 63 repo listings captured verbatim
from the HF API, chosen to cover every file naming pattern found across
1237 GGUF repos of the major publishers and pruned to whole quant groups.
Each repo pins its resolved plans and its cache listing.
The expectations follow what each file really is per its GGUF header,
not what the current resolver picks, so a mismatch is a resolution bug.
Mismatches are collected and reported together before the test fails.
* tests: leave the listing unchecked on paths the filesystem refuses
Some real split names (DevQuasar's Model.Q2_K.gguf-00001-of-00012.gguf
under a quant folder) exceed MAX_PATH once materialized in the temporary
cache on Windows, so the listing of such a repo is skipped with a note
while its plans stay checked.
* tests: pin real listings to master on GGUF convention names only
Replace the real repo table with 171 HF listings whose file names follow
the GGUF naming convention (lowercase sidecar prefix, - delimited
components, quant last), one per layout pattern found across 1174 GGUF
repos and pruned to whole quant groups. Repos outside the convention are
dropped. Each repo pins the plans and the cache listing master gives
today, so the test is a pure harness: any change in resolution shows up
here, and mismatches are reported together.
test-llama-archs included src/llama-arch.h and src/llama-model-saver.h,
which prevented building on Windows with shared libraries since the
used symbols are not exported from the DLL.
- declare llama_arch_* wrappers around the internal llm_ arch query
functions in the llama-ext.h staging header, together with
llama_arch_kv_name() and llama_arch_supports_save()
- slim llama_model_saver down to the private implementation of
llama_model_save_to_file(): the fixture-writer half used by the test
moves into tests/test-llama-archs.cpp as a local kv_writer
- replace the roundtrip saver usage with the public
llama_model_save_to_file() writing to a temp path (also removes the
tmpfile() fd leak and its Windows workaround)
- move test-llama-archs, test-generate-models, test-llama-context and
test-fusion out of the NOT WIN32 OR NOT BUILD_SHARED_LIBS guard

back in where it lands, quicker when opening a chat than when going back
to a new one. Its wrapper keeps the same height in both positions, so
the messages never shift while it moves.
The new-chat greeting fades in as the form settles, also on a refresh or
a first visit. Reduced motion keeps only the fades.

* ui : let the expanded sidebar be resized by dragging its edge
Bring back the desktop sidebar resize handle that was dropped with the
shadcn sidebar primitive. The width is clamped between 18rem and 32rem,
persists across reloads, and resets on a double-click of the handle. The
tab bar follows the same width so a wider sidebar never covers it.

* ui : rubber-band the sidebar edge past its bounds and drag it shut
Past the max width the edge resists harder the further it is pulled, and
the same happens below the min width until the pull passes 9rem, where it
snaps to the pointer and letting go hides the sidebar. A release outside
the bounds springs the width back to the nearest one.

* ui : show the sidebar edge strip faintly on hover and solid while dragging
The strip is clipped to the sidebar's rounded corners through its own
overlay, so the sidebar itself is never clipped.

* ui : remember whether the desktop sidebar is open across reloads
A phone opens the sidebar as an overlay, so it always starts closed there
and its toggling never overwrites the desktop preference.
Assisted by: Claude (Opus 5.5 Medium)
* ui : fade the sidebar labels and conversation list with its width
The fade follows the live width, so it tracks both the toggle's width
transition and a drag below the minimum width.
Assisted by: Claude (Opus 5.5 Medium)
* ui : persist the sidebar width on release and clamp a restored one
A drag now updates only the live width and writes it to localStorage once
when released. A width restored from localStorage is clamped to the
current bounds, so a value saved under older bounds does not stick.

* kv-cache : use ggml_backend_tensor_copy to refill the DSV4 K mirrors
* llama : move the Engram pad id to llama_hparams and the token map to llama_model
The saver no longer needs the deepseek41 model class.
* deepseek41 : drop the F32 src1 request on the HC mixes matmul
* ggml : add softplus TODOs in the backends that still use log(1 + exp(x))
* convert : make the DSV4/DSV4.1 modify_tensors generators, drop the redundant vision filter
* deepseek41 : clean up comments
* deepseek41 : drop the F32 src1 requests on the router and indexer matmuls
* convert : use format_tensor_name directly in DeepseekV4Model
* s/comp_kv_src/comp_il_src/g
* cont : fix TODOs for log1p

* cuda : use std::string instead of VLA for archName
Modernize the code (old C style) and fix the following warnings:
```
ggml/src/ggml-cuda/ggml-cuda.cu:180:19: warning: variable length arrays in C++ are a Clang extension [-Wvla-cxx-extension]
180 | char archName[archLen + 1];

ggml/src/ggml-cuda/ggml-cuda.cu:180:19: note: read of non-const variable 'archLen' is not allowed in a constant expression
ggml/src/ggml-cuda/ggml-cuda.cu:179:9: note: declared here
179 | int archLen = strlen(devName);

* common, grammar: add recursive depth limit, make it a requirement
* catch more recursive functions
* common : tidy up peg parser changes
* grammar : reject candidates in a loop, without a depth limit
The depth limit in llama_grammar_reject_candidates_for_stack counted
the code points of a vocab token, so any token of 256 chars or more
was always rejected under a grammar, such as the 512-space token of
GLM-4.7-Flash or the long space tokens of Laguna-S-2.1.
The rejection now walks the code points with its own stack of levels
instead of recursing: there is no limit and no stack risk, whatever
the length of a token from the GGUF, and the masks match master.
* grammar : track rejected candidates as indices into the input
At a given code point a candidate only differs from its input by the
position of its code point pointer, so the levels now carry indices
into the input candidates instead of copies. The first level needs no
special case and the rejects map back to the input directly.
Grammar sampling gets faster than master on GLM-4.7, Laguna, Qwen3.6
and gemma-4 with the json, list and spaces grammars, same masks.
* nit : shorten the comment of llama_grammar_reject_step
* common : add depth_guard for schema walks
* grammar : move GRAMMAR_RECURSIVE_LIMIT into the .cpp
* common : reduce recursion limit for peg parser
* improve
