* ui: add opt-in run_javascript frontend tool Expose a run_javascript tool to the model, executed entirely in the browser through the existing agentic loop. Code runs in a Web Worker inside a sandboxed iframe with an opaque origin, isolated from the WebUI and its API. Console output, errors and the return value are fed back as the tool result. The parent enforces a hard timeout by removing the iframe, which terminates the worker. Disabled by default, toggle in Settings > Developer. * ui: address review feedback from allozaur Use the JsonSchemaType enum for the tool definition parameter types instead of raw string literals, extending it with STRING and NUMBER. Move the worker shim and the iframe harness html into their own files so the service no longer carries inline source blobs. Replace the remaining magic strings with constants: SANDBOX_EMPTY_OUTPUT and SANDBOX_TRUNCATION_NOTICE, and reuse NEWLINE_SEPARATOR for joins. * ui: move sandbox worker shim to a raw imported file Replace the inline worker template string with a real sandbox-worker.js imported as raw text, and build the iframe harness from it in sandbox-harness.ts. The raw worker ships as a string, not a module, so it is excluded from eslint and the typecheck program.

This is a non-functional change. When using `--spec-type ngram-map-k4v`, the log messages at startup and runtime say `ngram-map-k`. Added logic in the in the constructor of `common_speculative_impl_ngram_map_k` to pass the correct `COMMON_SPECULATIVE_TYPE_NGRAM_MAP_K4V` when `config.key_only` is `false`. After this change, the log messages use the correct name.

* mtmd: add more validations * fix * refactor a bit * type check for get_arr_int
* server: SSE replay buffer, survives client disconnect
Opt in on POST /v1/chat/completions when the client sends
X-Stream-Resume: 1 and a non empty X-Conversation-Id. The conv id is
the session identity end to end, no extra opaque token. The drain
runs detached server side and buffers SSE bytes, the generation
survives HTTP disconnect, F5, or lets users switch from iOS Safari
to another app without losing the actively generated response.
Routes:
GET /v1/stream/<conv_id>?from=N replay
GET /v1/streams[?conversation_id=X] list, drives sidebar spinners
DELETE /v1/stream/<conv_id> Stop, idempotent
Router parent fans out to children for list and delete, probes on GET
to route to the owner, fans out DELETE on POST so "one session per
conv" holds across model swaps.
WebUI: the layout snapshots /v1/streams at mount and on
visibilitychange, the sidebar reflects live inferences across all
convs. The chat page reattaches on mount, append vs fresh is detected
from existing content so continue mid stream keeps its prefix.
update_slots: on llama_memory_seq_rm refusal at a deep position, full
clear of the seq and reprefill from zero instead of GGML_ABORT.
OAI strict path unchanged when the opt in headers are absent.
* server: create stream session only after post_tasks succeeds
* server, ui: drop X-Stream-Resume, X-Conversation-Id alone enables the replay buffer
* server: drop magic 17, derive the X-Conversation-Id header length from sizeof at build time
* refactor: address review feedback from ngxson
* server-context: cleaning
* server-stream: fix use-after-free on rd
Guard stop_producer with a shared alive flag, flipped by on_stream_end
before rd dies. Prevents a late cancel (session eviction by a later
POST on the same conv_id, or a DELETE arriving after the producer
ended) from touching a destroyed rd.
* ui: fix cross-conversation contamination
Scope streaming flags per conv so one finishing does not unflag the
others, guard discoverActiveStream against concurrent runs to avoid
duplicate attaches, and stop racing syncRemoteRunningStreams for the
sidebar set.
* server-http: keep request alive in detached SSE drain
The response next() lambda may reach into *request via &req long
after on_complete reset the request shared_ptr. Capture request in
the detached thread so it outlives the drain.
* ui: address review feedback from coder543
Forward Authorization to /v1/stream and /v1/streams fetches, the resumable routes
must obey --api-key like the rest of the API.
Wrap reader.read() in a try/catch, the underlying connection drop rejects with
TypeError instead of resolving done=true, treat it as a premature end of stream
so the existing resume loop kicks in.
Freeze the model at session start in chatStreamingStates.model and thread it
through cancel and resume, the dropdown selection may have changed since the
POST and the server side identity is fixed at that time.
* format
* ui: remove unused selectedModelName
* server-stream: poll session->is_cancelled() in stream_aware_should_stop
Address review feedback from coder543. The cancel propagation through
rd.stop() relies on the slot eventually processing the cancel task and
posting a result that notifies the recv condvar, remove_waiting_task_ids
does not notify directly. Add a defensive poll on session->is_cancelled()
so the producer-side next() loop exits on its next iteration after
cancel() without waiting for the cancel task to round trip through a slot.
* server-stream, ui: replace GET /v1/streams with POST /v1/streams/lookup
Address review feedback from coder543. Listing live sessions leaks the
conversation_id of every concurrent user, which defeats the random UUID
unguessability. The new route takes {conversation_ids: [...]} in the
body and returns matches only for the ids the caller already owns, so
foreign UUIDs stay private. The router fans out the same POST to every
child and aggregates, the WebUI passes the convs visible in its sidebar.
* ui: read conv ids from IndexedDB in syncRemoteRunningStreams
The conversations store is not hydrated yet at +layout onMount, so the
sidebar spinners stayed off for background convs until the user clicked
on them. Read straight from the DB to dodge the init race.
* server-models: deduplicate stream lookup timeouts behind one constant
* ui: extract visibility kick grace into a stream constant, bump to 1000 ms
* make it safer & more simple
* server-stream: survive client disconnect via stream_pipe::finish_producer
After the RAII rewrite the generation stopped the moment the client
disconnected. httplib bails its content provider on the is_peer_alive
check at the top of write_content_chunked, so returning true from the
provider never keeps it producing: the response resets, rd is destroyed
and its task gets cancelled.
Reinstate the disconnect survival inside the pipe. stream_pipe gains
finish_producer, which pumps the response next() into the ring buffer
until the generation ends, and mark_producer_done for the clean wire
end. server-http only triggers them: mark before sink.done on a clean
close, finish in on_complete when the peer left early. No detach, no
stream logic in server-http beyond the trigger, and the strict OAI path
is untouched when no pipe is attached.
Known limitation: finish_producer pumps synchronously on the http
worker, so a disconnected stream keeps its worker busy until the
generation ends. A follow-up will move the drain off the http worker so
no worker is held.
* server-stream: drain disconnected streams on a manager owned thread
The previous commit pumped the post disconnect drain synchronously in
on_complete, on the http worker, so a disconnected stream kept its
worker busy until the generation ended. Under a wave of reloads or tab
closes that pins workers from the pool.
Move the drain off the http worker. on_complete now hands the response
to stream_session_manager::adopt_orphan, which pumps it to completion on
a manager owned thread and releases the worker at once. One thread per
disconnected stream still generating, stored in a list, joined and
reaped on the next adopt, by the GC, and at shutdown. No detach, the
thread lifecycle is fully owned by the manager. needs_drain gates the
handoff so a cleanly finished stream never spawns a thread, and the
strict OAI path stays untouched when no pipe is attached.
stop_gc now cancels sessions before finalizing them, so an in flight
drain sees is_cancelled and exits instead of blocking the shutdown join
until the generation ends naturally.
* ui: add missing JSDoc
* server-stream: drain on the http worker, drop the manager thread
Address @ngxson review: httplib runs a large dynamic pool and a worker
blocked in next() sits on a condvar instead of burning cpu, so draining
the rest of the generation on that worker is fine and much simpler than
a dedicated thread.
on_complete calls finish_producer directly again. Removes adopt_orphan,
the orphan thread list and its reaping, the stop_gc session cancel that
only existed to unblock those threads, and the now dead drain_shutdown
flag.
* server-stream: split stream_pipe into producer and consumer classes
Address @ngxson review: one class covering both ends was messy. stream_pipe
is now a base holding the session and is_cancelled, with stream_pipe_producer
(write, mark_producer_done, finish_producer, cleanup, finalizes on destruct)
and stream_pipe_consumer (read only, no finalize) deriving from it.
Drops the is_producer_ discriminator and its runtime guards, the type now
encodes the role. res.spipe is retyped to shared_ptr<stream_pipe_producer>
since it is only ever a producer. No behavior change.
* server-stream: rename producer methods to unix pipe semantics
Address @ngxson review: mark_producer_done becomes done(), finish_producer
becomes close(), matching a unix pipe write end. The producer_done_ member
follows as done_. write() is unchanged. No behavior change.
* server, ui: route resumable streams via a conv map, persist resume identity
Address ngxson review: drop the polling probe, proxy_post records a conv_id ->
model map and the stream routes resolve the owning child with one lookup. The
map is the single source of truth, the ::model suffix stays for child session
uniqueness but the router never parses it.
UI: the server keys a session by the POST time identity (conv::model), but reload
probed with the bare conv id and missed model tagged sessions, so F5 stopped the
stream and sidebar spinners stayed off. Persist the model and rebuild the exact
identity on resume, single conv and bulk sidebar both send it.
Add unit coverage for the identity round trip.
* ui: resolve continue target by id to stop cross-conversation flash on switch
* ui: skip stream resume when the abort is intentional
* server: move the conv id to model map into a self contained tracker
Address review from ngxson: server_models held two mutexes side by side, the
global one and a bare conv_model_mu guarding a loose map, which made the locking
hard to follow. Wrap the map and its lock in a small conv_model_tracker struct
that owns its mutex, one mutex per struct. The remember, lookup and forget
methods move inline into the tracker, server_models exposes a single conv_models
member and the routes call models.conv_models.lookup and friends. No behavior
change, the map stays the single source of truth for routing resumable streams
to a child.
* ui: replace stream magic values with enums and shared constants
Address review from allozaur: lift the inline literals around the resumable
stream code into named symbols so the intent is explicit and reusable.
* ui: fold the stream resume and discovery helpers into ChatService
Address review from allozaur: drop the two standalone stream-*.service files.
They were used only by the chat service and store, carried no shared state, and
did not follow the static class pattern the other services use, so a separate
abstraction was not warranted. Move the helpers onto ChatService as static
methods. No behavior change, tests now exercise them through ChatService.
* docs: document the SSE replay buffer in server README-dev
Add the resumable streaming section, list stream_session_manager in the
backend component inventory, and link PR 23226 in the related PRs.
* ui: align attachServerStream call with onCompletionId param in handleStreamResponse
* server-http: rename del_ to del to match get and post
* ui: address review feedback from allozaur
* ui: drop duplicate SSE constants, keep sse.ts canonical
* ui: use svelte:document for the visibilitychange listener
address review from allozaur: replace the manual document.addEventListener
in onMount with a declarative <svelte:document onvisibilitychange>. svelte
handles attach, detach and SSR, so the typeof document guard and the onMount
cleanup go away. onMount keeps only the first load snapshot.
* server: trim redundant stream drain comments
Address review from ngxson
* server: balance and clean up stream comments
remove redundant comments and tighten the verbose ones across the resumable
stream code, keeping the concurrency and lifetime rationale that is not obvious
from the code. also fix two stale comments in server.cpp and server-models.h
that still described the old ::model suffix probe and fan out routing, now
replaced by the conv_id -> model map
Address review from ngxson
* ui: balance and clean up stream comments
dedup repeated rationale (frozen conv::model identity, the lookup privacy note,
the abort patterns) down to one canonical spot, tighten the verbose blocks, and
keep the concurrency and resume-offset reasoning. fix stale comments in
stream-identity.ts and chat.service.ts that still described the old loopback
probe and fan out routing, now the conv_id -> model map.

Tests are generally prefixed with -test, so rename export-graph-ops accordingly. rpc-server is probably too generic a name for /usr/bin. Because it should work with any ggml application, it is renamed to ggml-rpc-server.
* [CUDA] Added a cudaMemcpy2DAsync fast path to ggml_cuda_cpy Add a CUDA ggml_cpy fast path for same-type, same-shape strided copies that are just 2D pitched block copies. When tensors are not fully contiguous but each row is contiguous, it now uses cudaMemcpy2DAsync instead of the slow element-wise scalar copy kernel. This fixes the GDN recurrent snapshot update with -np 4, where rollback slots are separated by cache stride gaps. * Add new tests that execute the new optimized strided copy path * Return unsupported for strided copy in OpenVINO, as new tests are failing
* opencl: rework FA kernel for f16 and f32
* opencl: flash-attention prefill prepass kernels
- flash_attn_kv_pad_f16 pads the tail KV tile to a BLOCK_N multiple
- flash_attn_mask_pad_f16 pads the matching mask tile
- flash_attn_blk_f16 classifies each KV tile per query block as
fully masked / mixed / fully unmasked, so
the main kernel can skip fully-masked tiles
and the mask lookup for fully-unmasked ones
* opencl: FA kernels for q4_0 and q8_0
* opencl: `set_rows` for f32 to q8_0/q4_0
