* ui: land at the bottom of a conversation every time it opens
Opening a long conversation often stopped short of its end:
- the press grace counted from page load (pressedAt = 0), so a chat that
landed within 400 ms of a refresh did not follow the rows realizing
after the jump
- the click that opened a chat (sidebar row, tab) started the same grace,
so navigating by click had the same problem
- any scroll event away from the bottom stopped following, including the
ones the browser fires itself while the chat settles
- the chat screen outlives its routes, so going back to the last landed
conversation through the new-chat screen skipped the landing entirely
scrollToBottom() now clears the grace, only an upward scroll away from the
bottom stops following, and every navigation lands anew. Navigations into
a chat also disable SvelteKit's scroll reset, which moved the previous
conversation to its top for a few frames.
Where overflow-anchor is supported, a 1px pin after the messages is the
only scroll anchor while following, so the browser keeps the bottom in
place itself; WebKit keeps the resize observer.

* ui: let nested agentic content scrollers chain to the chat
Reasoning, shell output and code blocks used overscroll-behavior:
contain, so the wheel stopped dead at their edges instead of
scrolling the conversation.

* ui: stop following the stream as soon as the reader scrolls up
A trackpad or smooth wheel scrolls in steps smaller than the at-bottom
threshold, so each step up was re-stuck and snapped back on the next
growth while a response streamed. Any upward move that is not content
shrinking now releases at once.
The attach effect also read the hook's own state, so every flip
re-attached and re-measured, which undid such a release.

ChatFormActions gated the mic and stop buttons on a `canSubmit` prop that
ChatForm never passed, so it was always false and typing text did not swap
them for the submit button. Use `canSend` instead and also hide the

* ui: reveal the collapsed sidebar from its logo and toggle it there
The collapsed sidebar now shows only the logo; hovering it reveals the
icon strip until the pointer leaves. The expanded sidebar drops its
top-right collapse button and the logo collapses it on hover instead.

* ui: fade the peeked sidebar in at full width and keep the toggle slide
Hovering the logo of the collapsed sidebar now fades in the fully open
sidebar, floating over the page at its full width, instead of resizing
it. Opening or closing with the toggle still resizes and slides: the
sidebar docks to strip width while it slides, then floats out of sight,
and it stays hidden under the pointer after a toggle close. The unused
icon-only strip is removed from the sidebar actions.

test_cancel_request enables context shift so the generation only ends
when the request is cancelled, then polls /slots with a deadline.
Without context shift the generation fills the context and frees the
slot on its own on fast machines, so the test passes even with
cancellation disabled.
test_server_sleep uses the existing wait_for_sleep helper instead of a
fixed sleep.
* common: bound control vector layer indices by the model layer count
A direction tensor layer index is parsed from the tensor name with no
upper bound, and the buffer size and write offset are computed in int.
A large index overflows both, so the accumulation writes before the
start of the buffer.
Pass the model layer count to the loader, reject indices above it like
the existing zero index check, and compute the sizes in size_t.
* mtmd: fill M-RoPE positions by whole merge tiles
The position loops of the Qwen-VL, GLM, PaddleOCR and Qwen2.5-VL
encoders hardcode a 2x2 merge inside a stride of n_merge, so a patch
grid that is not a multiple of the merge writes past the positions
buffer. Iterate over whole merge tiles with n_merge inner steps, which
bounds the writes by the patch count and gives the same positions on
aligned grids.
PaddleOCR also requires a merge aligned image at graph build, as the
Qwen-VL family already does.

* ui: build the reasoning menu from the template effort levels
When the chat template reports effort levels, the menu offers Default,
Off and those levels, and a pick is sent as reasoning_effort. A
template that reports none keeps the token budget menu.
Picking a model other than the one that produced the last answer resets
the conversation effort to Default, and an effort the current menu
lacks resolves to Default.
* ui: wait for a cold router model before building the request
A router serves the props of a loaded model only, so a request sent to
a cold model was built without its template effort levels and fell
back to a token budget. The request now waits for the model to load,
joining a load already in flight, and a stop during the wait sends
nothing.
Status waiters hold a list per model so a load and the requests that
wait on it each get theirs, and a props request in flight is shared
with a second caller instead of answering null.

* server: expose the reasoning effort levels of the chat template
The capability probe renders a user turn for each candidate level
(minimal, low, medium, high, xhigh, max) and for an unknown level. A
level is honored when it renders without raising and differently from
the unknown level, which shows the template fallback. Levels sharing a
render are aliases and the highest one is kept.
The caps serialize to JSON, and chat_template_caps in /props reports
the list as reasoning_effort_levels, from lowest to highest.
* jinja: keep the caps free of the json dependency
The caps keep reporting their flags as a map, and the effort levels
stay a plain member. common_chat_templates_get_caps() builds the JSON
the server reports from both, so jinja depends on json only for the
probe inputs.

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.

* 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.

The model info actions in the selector used to navigate to the models page

* ui : fit the chat column below the tab bar
The tab bar reported 1.25rem of its height while it takes 3.3125rem (pt-3.25 + h-10), so a short conversation still left a few pixels to scroll. Use the bar's full height and drop the extra 1rem from the column's minimum height, so it fills the viewport exactly; the centered new-chat form moves up by the same 1rem to keep its place.

* ui : stop scrolled dialogs from bouncing past their ends
Dialogs scroll on their own (the settings panel, the search results), so the page rule did not reach them and their sticky navigation still jumped on overscroll.

and the bottom. It fades out drifting toward where it goes and fades
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.
Assisted by: Claude (Opus 5.5 Medium)
* 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.
Assisted by: Claude (Opus 5.5 Medium)
* 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.

* chat : reject JSON nested more than 128 levels before walking it
The schema builder, the jinja engine and the decision code walk request
JSON with recursion. A request nested deep enough overflows the stack of
the HTTP thread and llama-server dies (SIGBUS on macOS, SIGSEGV on Linux):
for a tool schema from a few hundred levels on macOS and about 10000 on
Linux.
Check the depth first and answer 400 past 128 levels: the chat inputs in
common_chat_templates_apply (tools, tool-call arguments,
chat_template_kwargs, json_schema), the json_schema of /completion, and the
whole /v1/systemone body. A gemma4 tool result that is too deep stays text.
* fix the root, not the call side

* ui : move models manager to its own route, keep Discover as a dialog
Models now lives at #/models instead of a dialog. Discover opens as a
standalone dialog over it, and leaving the page returns to the chat it
was opened from.
Assisted by: Claude (Opus 5.5 Medium)
* ui : polish the models page layout and filters
Give the models page a page header with the Discover action, calmer
column labels, tinted section and family headers, and an empty state.
Load the model list on a direct visit, slide the detail pane over the
table below xl, and draw the filter toggles as one box matching the
context select, with room for their shadow.

* ui : round the models table family headers

* ui : fix models page navigation and Discover gating
Record the models page's way back after every navigation, so Back,
a typed URL or a reload no longer return to a stale chat. Escape
closes the detail pane, then leaves the page. Gate every Discover
entry point on one shared check, recheck the API key on /models,
skip the duplicate router fetch on a direct load, and share the
route load between pages.
Assisted by: Claude (Opus 5.5 Medium)
* ui : show model details in a drawer
Open the models manager's detail pane in a drawer, from the right on
desktop and from the bottom on a phone, instead of an inline side
panel and a full-screen cover. Pad the pane on both sides, drop its
close button on a phone, and assert that filtered rows are gone from
the page rather than merely hidden.
Assisted by: Claude (Opus 5.5 Medium)
* ui : make whole models table rows clickable
A click anywhere on a model or quant row opens it, unless it lands on
one of the row's own controls (load toggle, actions menu). The name
button stays the keyboard path to the same action.

Use the dropdown menu surface (border, radius, background, shadow,
padding) for the hover card and the context gauge popup, and fix the
hover card open/close animation to use bits-ui data-state attributes.

* mtmd : lfm2 bilinear resize matches torchvision
Lfm2VlImageProcessor and d1-omni vision.py resize uint8 images with
torchvision (antialias=True). That is Pillow's algorithm, except that the
weights are int16 with as many fractional bits as the largest weight allows,
where Pillow uses 22 bits. The Pillow port was 1-2 levels off on about 1% of
the values of the d1-omni and LFM2.5-VL crops.
RESIZE_ALGO_BILINEAR_TORCH rounds the weights of the Pillow port to that
precision and scales them back to 22 bits, which gives the output of
torchvision with the same passes, and "bilinear" maps to it for LFM2 and
d1-omni. Other models keep the Pillow algorithms.
* mtmd : lfm2 bicubic resize matches torchvision
Lfm2VlImageProcessor resizes with torchvision for the bicubic checkpoints too
(d1-3B, LFM2-VL), so "bicubic" maps to RESIZE_ALGO_BICUBIC_TORCH for LFM2: the
Pillow bicubic filter (a = -0.5, as torchvision with antialias) with the int16
weights of torchvision. The Pillow port was 1-2 levels off on about 0.25% of
the values of the d1-3B crops.
* use bitfield, add hparams setter

Add Soprano-80M and Soprano-1.1-80M (https://huggingface.co/ekwek/Soprano-1.1-80M)
as an audio generation model: a Qwen3 backbone plus a Vocos decoder that runs
as a gen-only mmproj.
- convert: detect Soprano checkpoints and export the backbone as qwen3 and the
decoder.pth Vocos weights as the mmproj
- vocab: add the soprano pre-tokenizer (lowercase, whitespace collapse,
per-digit split, [UNK] fallback)
- mtmd: add the Vocos graph and ISTFT, allow loading a gen-only mmproj for
Soprano and include the gen-audio context in mtmd_get_memory_usage
- mtmd-helper: add the Soprano pipeline; the decoder runs over the whole
utterance, so stream mode sends the audio in one chunk after flush()
- tts: document Soprano usage

Run npm audit fix, then bump the remaining vulnerable packages within
their current majors: storybook 10.6.2, vitest 4.1.12, vite 7.3.7,
@modelcontextprotocol/sdk 1.32.1, dompurify 3.4.17, mermaid 11.17.2,
@vite-pwa/assets-generator 1.0.4 and @tailwindcss/typography 0.5.20.
Override katex to 0.18.11 and postcss-selector-parser to 7.1.6 since
their dependents still pin vulnerable ranges, bump the sharp override
to 0.35.5, and pin @storybook/svelte so npm does not resolve the 11.0
alpha through the addon-svelte-csf peer range.
Storybook stays on 10.6.2 as 10.6.3 is newer than min-release-age.

* server: realtime API: send complete after committed audio drains
* server: realtime API: complete a commit at its end row
Completion is triggered when the stream runs dry, which is a timing
proxy: audio appended while the tail drains leaks into the committed
item, a final commit before the drain merges both items, and back to
back commits collapse into one.
mtmd_audio_stream_flush() records the row count at the end of the
flushed audio (mtmd_audio_stream_get_n_rows_flushed), next to the rows
produced so far (mtmd_audio_stream_get_n_rows). The slot keeps a FIFO
of these end rows and completes each commit once every row up to it is
decoded.
