The teardown comment claimed that terminate() closes the child stdout.

In the attachment preview, SyntaxHighlightedCode's wrapper (overflow-auto) was not the element that ended up owning horizontal overflow: the inner code box kept its content clipped at the wrapper's width, so a single line longer than the preview pane was cut off with no scrollbar (scrollWidth == clientWidth while the code's own content measured tens of thousands of px).
Give the pre/code boxes their intrinsic width (width: max-content, min-width: 100%) so long-line overflow propagates to the scrolling wrapper. Verified in the running WebUI: with a 6000-char line, wrapper scrollWidth goes from 990 (clipped, unscrollable) to 50449 with a working horizontal scrollbar; short content still fills the container exactly as before (min-width: 100%).
Fixes#30796
The fused moe_reduce kernel computes dst = sum(experts[e] * weights[e]) in a
single dispatch, reading experts and weights while writing dst. The graph
allocator computes tensor liveness on the unfused graph, where the inputs are
fully consumed by earlier nodes of the fused group, so it can legally recycle
the input memory as dst. In the fused kernel this becomes a
threadgroup-vs-threadgroup race that produces rare non-deterministic wrong
results (observed with test-llama-archs -a kolibri on the meta backend).
Reject the fusion when dst overlaps either input, same guard as the
mul_mat_add fusion. The unfused MUL + ADD path is always correct.

* cuda: cap Stream-K blocks at the number of k-blocks
Stream-K normally launches one CUDA block per SM. For small matrices,
this can exceed the total number of output-tile/k-block pairs, leaving
blocks with no work and adding launch and fixup overhead. Cap the grid
at that count to remove these excess blocks without changing the useful
rounded K ranges or numerical results.

* ui : resume model downloads from the pause point
A stopped download keeps its partial file instead of deleting it, so

* ui : make resuming a paused download work
Re-posting the tag of a paused download hit the router's "already
exists" check, because a paused download parks its entry as DOWNLOADED

replaced and resumed. The UI keeps the paused row when the request still
fails, instead of dropping it and looking finished.
Assisted-by: pi
* ui : remember unfinished model downloads
A partial file is named after its content hash, so nothing on disk says
which model it belongs to once the router restarts. The router now keeps
the tags of the downloads it started, clears a tag when the download
finishes or is deleted, and lists what is left as still downloading
without starting anything. The UI adopts those tags as paused on every
list fetch, so a refresh or a fresh open shows an incomplete download and
can resume it from the files already on disk.

* common: settle sidecar names on the listing and drop unfinished partials
An infix or trailing sidecar token is ambiguous: draft heads use it
(Model-MTP-BF16.gguf), so do full models with embedded heads
(Model-Q8D-MTP.gguf). Such a name is a sidecar only next to token-free
main weights of the same family, while mmproj or imatrix anywhere in the
name, or a leading token, decides alone (mmproj_f16.gguf).
A quant tag always carries its bit count, so a sidecar named after no
quant (mtp-Model-it.gguf) gets the bare tag: the listing, the plan and
remove all use it. An imatrix tag resolves into a plan slot of its own,
downloaded but never wired into the params.
remove resolves the tag the way a download does and deletes the partial
files of every planned blob, so cancelling a running download or
dropping one left unfinished by an earlier run leaves nothing on disk.
The router passes its token and releases its lock around the call, and
records the unfinished downloads with an atomic write.
llama download succeeds on a sidecar-only plan and prints its paths.
* ui : move dialog views and draft states into enums and constants

* ui: dedupe draft sidecar badges per quant
The draft sidecar badges deduped by kind and repo without the quant, so
with a draft cached at two quants only one badge survived, and a delete

* ui: adopt the incomplete download status and drop the paused-ids registry
The store inferred an unfinished download from a downloading entry it
held no local state for, which misread a download running in another
tab as paused and offered a resume the server rejects. The listing
carries the "incomplete" status now, so the adoption keys off it
directly.
The paused ids no longer need to survive in localStorage: the server
remembers them across restarts, and the progress snapshot was stale
after a reload anyway. The stale localStorage key is removed.

* server: download a model with its sidecars as -hf does
Resolution goes back to master. POST /models takes the sidecar kinds to
pull with the model (mmproj by default) and the download child gets them
as -hf flags, so the server picks the files. /models lists real models
only, each with the sidecars it has on disk, and incomplete downloads
keep their sidecars across restarts. A stopped download keeps its
partial files for the next attempt, and DELETE purges them through the
same plan the download follows.
* ui: download sidecars as parameters of their model
The download options keep their chips, but a chip no longer posts a
sidecar tag: the store maps it to its model and the sidecar kinds to
pull, the quant chip takes its companion draft in the same download,
and draft badges come from the sidecars each cached model lists.
The server adds the sidecars a cached model lacks when it is posted
again, and DELETE removes a single sidecar of a cached model.
* ui : mirror the server's sidecar lookup in draft badges
The server resolves a sidecar by the case-sensitive `<kind>-` token in the same
directory as the weights. The UI matched the token loosely, so a badge could
offer a draft the server never pulls.
Assisted-by: DeepSeek-V4.1-Flash
* ui : post the model's sidecar kinds with its download
The store keeps one download per model: the chip's kinds ride along with the
model's own sidecars, and a download row no longer expands into one row per
sidecar. Draft badges carry no quant of their own yet, so a sidecar of a cached
model is never labelled with the model's quant.

* ui : join a quant's draft into its download chip
One chip per quant, its draft badged inside it and its size covering both

16-bit head.
Assisted-by: DeepSeek-V4.1-Flash
* ui : drop the draft download rows from the manager and selector
A download is one row per model again: the drafts ride with it, and the rows

Assisted-by: DeepSeek-V4.1-Flash
* ui : keep the discover download list one row per model

* ui : keep the discover chips readable in dark mode
The metadata chips, the chat template button and the View on Hugging Face link

* ui : carry the draft through the download options
One chip per main quant, its draft badged on it and the chip's downloaded state

names the draft type, so -hfd is gone.

* common : drop the partials of a removed sidecar
Removing a sidecar alone left the .downloadInProgress files of the sidecars a

* server : name why a download is refused
A model that is already downloading, or that is running, answered "already

Assisted-by: DeepSeek-V4.1-Flash
* ui : post a download once per click
Two quick clicks on the same chip posted twice, and the second answer was
"already exists". The store tracks the model as pending, returns early while it
is pending or in flight, and reads it as in flight before the server answers, so
the chip shows the download at once. The new client test pins the flows: one
POST per double click, the chip reading downloaded once the list reports the
model, a resume keeping its sidecars, a cancel dropping the whole download, and
a reload restoring the paused state.
Assisted-by: DeepSeek-V4.1-Flash
* ui : keep a plain download row the height of the others
The sub-lines wrapper of a download row was rendered even with nothing in it, so
its padding made the row taller than a plain one and the overlaid progress bar

in the discover list, and the selector row takes the phone padding its
neighbours have.

* ui : badge a repo's draft once
The args of a loaded model and the listing of a cached one report the same draft
in different words, one with the file's quant and one with the kind alone, so

per kind now, the args one winning as it knows the quant, and the test pins both
sources of a real repo.

* server : report the sidecars of a preset or a download on its way
A model the preset also names is registered as a preset, so its drafts were
never reported and no row could badge them. A download on its way reported none
either, though the record of the kinds it pulls is right there: those win over
the plan now, the plan resolves through the preset's hf-repo, and a models dir
stays out of it.

* ui : badge a download's drafts and open its model from the row
A draft still coming down badges the model id now, the way a landed one does,

focus on a download row so its panel opens.
Assisted-by: DeepSeek-V4.1-Flash
* common : report a removed sidecar that only had a partial
Removing a sidecar alone dropped the result of the partial purge, so a sidecar
that only ever landed as a .downloadInProgress blob answered false and the UI
had no reason to refetch. The purge result is folded into the return now, and
the test covers a partial-only removal.
Assisted-by: DeepSeek-V4.1-Flash
* ui : ignore a pause while the download POST is still on its way
The chip reads as downloading before the server answers, so a quick second click
unloaded a model that had not started and left the store neither in flight nor
paused. A pause returns early while the POST is pending, before it touches the
feed or the paused marker. The client test holds the POST open and pins it.
Assisted-by: DeepSeek-V4.1-Flash
* ui : offer a missing draft as its own chip
A model already on disk without its draft had no way to add it: the quant chip
carried the draft, so it read as a download of both. The quant chip keeps to its
own state now, its joined draft shows only while it rides along or is on disk,
and a downloaded quant missing its draft gets a chip of its own - badge, size,
download - that posts the model with that kind, so the server keeps the files
already there and pulls the draft.

* server : list a paused sidecar download by the files on disk
A model on disk whose sidecar download stops keeps its unfinished record,

The planned kinds now stand in only while the download runs.

A preset on a local file has no HF repo, yet the listing resolved its name

unfinished_downloads_get and unfinished_downloads_remove.

The resolution, the cached listing and the removal follow a single
table of sidecar kinds, so a kind is declared once with its file
keyword, whether it is a draft, its option and its plan file. The
server reads the same table for the kinds it accepts, the default
sidecars and the child flags.
Removing a tag keeps the files another cached tag still loads, such as
an mmproj named after the removed quant. A sidecar removed on its own
goes for every tag that resolves it.
An unfinished download records the exact paths of its partials when
it starts. A removal deletes those without asking the hub, and keeps a
partial another recorded download also writes. The record is taken
once the child is spawned, and the files go under the models lock, so
a download of the same tag cannot start while they are removed.
* server: drop stale partials and refuse a tag that resolves nothing
Recording a download again deletes the partials of the earlier record
that the new plan no longer writes, such as those of an older hub
revision or of a sidecar the new request leaves out.
A posted tag that resolves no file of the repo is refused before the
download starts. Removing a model follows a single path, whether the
reload erased its entry during the wait or not.
* server: fix the CI race between the router download tests
The pytest workers run in parallel on one shared cache, so a download
test could find the file another test had just fetched and see no
progress, or start from the unfinished downloads record another test
wrote. Each download test now runs on an empty cache of its own.
* server: refuse a DELETE of an unknown name and decide downloads in load()
A DELETE of a name that is neither a model nor a recorded download
went to common_download_remove, and without a tag it wiped the whole
repo cache, including the files of a loaded quant or of a download on
its way. Such a name is now not found, as it was before.
A POST that downloads over an existing entry checked its state outside
the lock, so a load of the same model in between got its instance
killed. The checks now run in load(), under the lock, right before the
spawn. The fake load time of the tests applies to model loads only,
since a download worker loads none.
* server: add incomplete_sidecars to the /models API
A sidecar added to a cached model and then paused kept its record, but
the listing showed only the complete model, so a fresh UI lost the
pause. The model entry now carries incomplete_sidecars, the kinds its
unfinished download has not written yet; a POST with the kind resumes
one and a DELETE with it drops its partial.
* common : drop a kept partial when a resume gets 416
Now that partials survive between attempts, an old or complete
partial makes every retry fail with the same 416.
Delete it so the next attempt can start over from zero.

* common: drop a kept partial when a resume gets 200
A server that ignores the range answers 200 to a resume, and the kept
partial then fails every attempt the same way a 416 does. Drop it as
well, so the next attempt starts over without a range.
* server: refuse a download that shares a partial with one on its way
Two downloads of quants that share a file, the mmproj or an mtp picked
by the closest bits, appended to the same partial and renamed a file
with interleaved bytes. A download whose plan writes a partial that a
running download also writes is now refused until that one is done.
* common : check the saved etag before resuming a partial download
Before resuming, compare the etag saved with the partial to the one
the server now serves. If it is missing or different, start over,
so a resumed download never mixes bytes from two versions of the file.

* tests: give the random model generator a per-tensor filler table
Muse Spark makes test-llama-context fail on state_load, cp_h and cp_d on about
six percent of the random seeds, with an NMSE of 1.0e-05 to 1.4e-05 against a
threshold of 1.0e-05. The sliding window is what exposes it: a restored state
keeps the window alone, so the attention of an SWA layer reduces over a
different cell layout and the continuation is not bit exact. Every SWA model
carries that, at 1e-08. Muse Spark carried it at 1e-05.
The generator is what turns 1e-08 into 1e-05. A norm preserving residual gate
holds alpha^2 + beta^2 == 1 and the conversion resolves both weights from one
raw weight, while the generator draws every tensor on its own. The pair then
scaled the stream and the branch independently, the stream lost an arbitrary
factor at each layer, and the model became an amplifier. The weights the test
ran on were not a Muse Spark.
Per-tensor rules lived inside the write path, where a flag picked the values of
a tensor inside each of the two branches that store them, so a new rule meant a
new flag threaded through both. The file asks to be rid of that in a TODO of its
own. Give each rule a filler, pick one from a table keyed on a substring of the
tensor name, and keep a single write path behind it. Mamba moves into the table
and Muse Spark joins it: the gate filler draws the raw weight once per block and
resolves alpha and beta the way the conversion does.
Over a thousand seeds on a CPU build the worst case drops from 1.36e-05 to
2.48e-06 and the median from 4.10e-06 to 5.48e-07, with no seed above the
threshold. The other 131 models come out identical to the bit, since no other
architecture carries these tensors. ctest is green on a CPU build and on a CUDA
build.
* tests: draw every tensor filler from fill_normal
The fillers repeated the generator and the distribution each time. The
normal draw now takes its key and the other fillers transform its
values, so the generator lives in one place. The generated models are
identical to the bit.

* model : add Kolibri-1 (Aleph-Alpha) support
Kolibri-1 is a bilingual German/English MoE reasoning model with 78B
parameters and 3.46B active per token: 50 layers, 384 routed experts plus
one shared expert.
Attention interleaves four sliding layers at a 513 window with one full
layer. The sliding layers rotate with NeoX RoPE, the full layers are NoPE.
GQA runs 48 query heads against 4 KV heads at head_dim 128 with a
QK-RMSNorm, and every block carries four RMSNorms, so the attention and the
MLP output are normalized before they rejoin the residual stream. Routing
picks the experts from logits + expert_bias and weights them with the
sigmoid of the unbiased logits, without renorm.
The converter reuses AfmoeModel for the per-expert checkpoint layout and
the expert selection bias, and writes the shared expert and the per layer
sliding window pattern. The released FP8 checkpoint needs no special code,
it goes through the generic weight_scale_inv path. Three tensor names are
added to the mapping (post_attn_norm, post_ffn_norm,
moe.router.expert_bias) and the 128k vocabulary registers the qwen2
pre-tokenizer by hash. The arch is registered in test-llama-archs, with GQA
and the sliding window pattern.

* feat(convert): Attempt to come up with 256 single-token, semantic option markers
Each switch model needs to identify a collection of single-token option
markers that can be mapped to their respective logits for the output
probability distribution. The simple upper/lower/numbers set only yields 66
unique markers, but the model can support up to 255. The challenge is that
which combinations of characters result in single-token markers is model-
specific, so we do a discovery exercise at conversion time by looking
through the specific model's vocab for single-token sequences of 1+ plain
letter strings (eg `A`, `AA`, `BB`, etc).

softplus_f32 and tile_softplus_f32 ran a scalar logf(1.0f + expf(x)) loop.
Replace both with a shared hvx_softplus_f32_aa() helper built from the
backend's existing hvx_vec_exp_f32 / hvx_vec_log_f32 primitives, so no new
numerical approximation is introduced.
hvx_vec_exp_f32 clamps its input to (-88, 88) before exponentiating, so a
naive log(1 + exp(x)) composition would saturate to ~88.72 for large x
instead of returning x. The Q6_V_vmux_QVV select keeps the scalar
reference's x > 20 guard (ggml_compute_softplus_f32 in ggml-impl.h),
which is what makes the vector path match the CPU result.
