* (qwen3vl) Correct calculation for injection point of deepstack image embeddings
INjection point for deepstack embeddings used Hyperparameter n_embd_inp(), which caused the hidden state to be double accounted for, causing an OOB array access. The correct accessor is n_embd()
* Fix m-rope when pipeline parallelism is enabled
The MMA flash-attention dispatcher only instantiated ncols2 = 8 and 4 for
head_dim 512, so any other GQA ratio hit GGML_ABORT. Gemma 4 12B's global
attention layers use head_dim 512 with a 16:1 GQA ratio (16 query heads /
1 KV head), which aborts at load. Because MTP speculative decoding requires
flash attention, this also blocks the Gemma 4 12B MTP drafter entirely.
Instantiating ncols2 = 16 there is not viable: it exceeds the maximum dynamic
shared memory on Ada (cudaFuncSetAttribute returns invalid argument). Instead,
route gqa_ratio % 8 == 0 (covering 8 and 16) through the existing ncols2 = 8
kernel, which already iterates over Q-head groups (iter_z = ceil(gqa_ratio /
ncols2)). gqa_ratio 8 and 4 behavior is unchanged; this mirrors the divisor
dispatch already used for the 576x512 case below.
Verified on RTX 4070 Ti SUPER (Ada, cc 8.9): Gemma 4 12B + MTP drafter now
runs with flash attention; draft acceptance 43-95% by workload, 1.5-2.2x
end-to-end speedup. The 26B-A4B drafter (gqa_ratio 8) is unaffected.

* webui: add custom CSS injection via config
register a customCSS setting in the Developer section under Custom JSON,
syncable so it rides the existing ui-config pass through. inject the value
into a single style element in the head, reactive on the setting. lets an
operator theme a prebuilt binary through --ui-config without rebuilding,
and lets a user set it from the settings panel.
move the textContent write into a use: action on the head style node.
the action is the idiomatic way to touch a node, so the no-dom-manipulating
lint rule is satisfied without a disable. value stays text through
textContent, never parsed as HTML.

server: real-time reasoning interruption via control endpoint (#23971)
Builds on the manual reasoning budget trigger from #23949. Adds a
CONTROL task that mirrors the CANCEL path on the live slot and calls
common_sampler_reasoning_budget_force to end thinking mid-generation.
POST /v1/chat/completions/control with { id_slot, action }, opt-in
reasoning_control arms the budget sampler on demand. Router and single
model. Minimal WebUI button as a skeleton for further UI work.
* ui: track reasoning phase via explicit streaming state
Add isReasoning to the chat store, mirroring the isLoading pattern:
per conversation map, private setter, public accessor and reactive
export. Set from the stream callbacks, true on reasoning chunks, false
on the first content chunk, reset on stream end and resynced on
conversation switch. The skip button now keys off isReasoning so it
shows only during the thinking phase, not the whole generation.
* ui: extract control endpoint and action into constants
Move the chat completion routes, the slots route and the reasoning
control action out of chat.service into api-endpoints and a dedicated
control-actions module. No behavior change, drops the magic strings so
the control protocol has a single source of truth.
* server: target reasoning control by completion id
Address @ngxson review on the control endpoint.
Switch from id_slot to the chat completion id to avoid a TOCTOU: the
slot can be reassigned between the lookup and the control request, so
matching the live completion (oaicompat_cmpl_id) is safe and a finished
one simply matches nothing. Rename the action to reasoning_end, guard
it on the reasoning_control flag of the target slot, and reduce the
response to {success} with an optional message.
* ui: target reasoning control by completion id
Keep the streamed completion id on the message and post it back to the
control endpoint instead of probing /slots. Drops the slot discovery
and the TOCTOU that came with it. Action renamed to reasoning_end,
response read as {success}.
* server: address review from @ngxson
Move the control fields into task_params and drop the redundant
comments on the control path.
* server: document the reasoning control endpoint
* Update tools/ui/src/lib/types/database.d.ts

* ui: rename cmplId to completionId
Per @allozaur review, clearer name for the streamed completion id.
* ui: wire completion id capture through the agentic flow
The webui streams through the agentic flow, which relayed onModel but
not onCompletionId, so the completion id never reached the message and
the control request was never sent. Relay it through the flow and its
callbacks type, declare id on the chunk type, and log an explicit error
when the button fires without a usable id.
* ui: target reasoning control model from the message
The model is a property of the completion, so read it from the streaming
message like the id, not from the model dropdown which is unrelated UI
state. Makes the request self-consistent by construction instead of just
unlikely to drift.

* fix: Model tags
ui: simplify network error handling (#23431)
Previously error to string conversion was split in two different files,
with one converting errors into strings, and another function analyzing
those strings to generate yet another string.
Now the the error handling for network fetches has been centralised and
uses directly HTTP error codes whereas possible to generate the
human-readable error strings.
It also fixes an issue where all JSON errors reported from the backend,
such as "Invalid API key", would get turned incorrectly in to
"Failed to connect to server" due to poor matching logic in the
now-gone getErrorMessage function.

* webui: fix tool selector toggle/counter, key tools by stable identity
Key the disabled set, counts and toggles by a stable per-tool key
instead of bare function name, deduped from one canonical list. Per-tool
checkboxes become presentational (single row handler, no nested button),
category checkboxes drop the tristate (n/total carries partial). One
getEnabledToolsForLLM keeps normalized MCP schemas and dedupes by name.

* fa: fix FlashQKV early-termination causing S=0 assertion with --parallel N>1
The backward-scan optimization in compute_helper/compute_helper_q checks
only one mask position per k_step block on the last query row (q_step-1)
to find where valid KV entries end. When q_step > 1 and different query
rows have non-overlapping valid KV regions (multi-slot / --parallel N>1),
the scan on the last row's mask can miss blocks that contain valid entries
for earlier rows. This causes those rows to accumulate S=0, triggering
the GGML_ASSERT(S > 0) in normalize_and_store_1row.
Fix: remove the early-termination scan at all 4 sites and iterate all
nk1/k_step blocks unconditionally. The mask already handles correctness:
fully-masked blocks produce smax=-inf and skip V accumulation, so the
performance cost is minimal for TG (small nq1) and acceptable for PP.
Fixes#809
* fa: refactor multi-slot mask fix into mask_effective_nk1() helper
Replace 4× inlined early-termination scans with a shared helper that
computes the effective K boundary by scanning ALL query mask rows
(union-of-masks). This is the minimal fix for multi-slot parallel
inference where different slots have different sequence lengths.
The helper returns the k_step-aligned boundary covering the longest
active sequence across all rows, preserving single-slot performance
(single row = same boundary as before).
