fix(langgraph): make concurrent DeltaChannel writes deterministic on
replay

Concurrent same-superstep writes to a `DeltaChannel` could reconstruct
from a
checkpoint differently than they were applied live, because live
execution
ordered them by task path while savers replayed them by task id. This
fixes that
    divergence in two complementary ways:

- Plain concurrent writes are now applied in the canonical `(task_id,
idx)`
order on both paths: `_applyWrites` orders them that way live, and the
`getDeltaChannelHistory` walk enforces the same order so reconstruction
matches live for every saver (Postgres, SQLite, MongoDB, Redis, and
custom).
- An `Overwrite` now wins its entire super-step: every sibling write in
the same
        step — before AND after the `Overwrite` — is discarded, matching
`BinaryOperatorAggregate`. This makes the result independent of the
(unstable)
ordering of concurrent fan-in writes; previously a plain write that
landed
        after an `Overwrite` in the same step was still folded in.

To keep reconstruction in sync with this `Overwrite` rule, any
`DeltaChannel`
that sees an `Overwrite` in a super-step is now force-snapshotted at the
next
checkpoint (and, under `"exit"` durability, in the final checkpoint).
The
post-overwrite value is materialized into `channel_values`, so a cold
read seeds
from that snapshot and never has to replay across the reset — making
live and
reconstructed state identical without changing the sparse-replay history
shape.
    These delta-channel APIs remain Beta.

fix(langgraph): forward task metadata and name subagents via
lc_agent_name

`mapDebugTasks` now forwards filtered user-meaningful task config
metadata
(including `lc_agent_name`) onto `tasks` stream payloads. The lifecycle
    transformer uses that metadata to set subagent `graph_name` from
`lc_agent_name` and recover `cause: { type: "toolCall", tool_call_id }`
from parent tool-dispatch tasks. Adds the shared
`EXCLUDED_METADATA_KEYS`
    constant to `@langchain/langgraph-checkpoint`. Ports langgraph#7928.

fix(langgraph-checkpoint-redis): persist and reconstruct full
`channel_values` across multi-node graphs.

`RedisSaver.put()` delta-filters `channel_values` to only the channels
written by the current node, but `getTuple()` had no reconstruction
logic — unlike `PostgresSaver` — so any multi-node graph whose last node
wrote a subset of channels silently lost the others. Each changed
channel is now persisted as a version-keyed `checkpoint_blob:*` entry in
`put()` and missing channels are reconstructed from those blobs on read.

`deleteThread()` now also deletes the `checkpoint_blob:*` keys. Without
this the blobs introduced above would orphan forever (memory growth) and
thread deletion would be incomplete, matching
`PostgresSaver.deleteThread()` parity.

When `ttlConfig.refreshOnRead` is enabled, reads now refresh the TTL of
the reconstructed `checkpoint_blob:*` keys alongside the checkpoint key.
Otherwise a read would keep the checkpoint alive while the blobs it
depends on expired, silently dropping reconstructed channels.

On write, `put()` now refreshes the TTL of every blob the checkpoint
references (the full `channel_versions` set), not just the channels
changed by the current node, so carried-over blobs from earlier nodes
expire in lockstep with the checkpoint doc. This write-side refresh is
independent of `refreshOnRead`. The per-channel blob writes also now run
in parallel.

Known limitation: with TTL enabled, a carried-over blob can still be
lost if it expires during an idle gap longer than `defaultTTL` (no read
or write refreshed it in time). When that happens the channel is left
cleanly absent on read rather than erroring. Fully closing this gap
(re-persisting expired blobs) is tracked as a follow-up.

fix(langgraph): merge instead of overwrite in `ensureLangGraphConfig`

`ensureLangGraphConfig` now per-key merges `callbacks`, `tags`,
`metadata`,
and `configurable` across configs instead of last-write-wins, so values
bound via `.withConfig({...})` survive when a later (e.g. invoke-time)
config supplies other keys. The merged dicts are fresh objects, fixing a
by-reference mutation of shared base configs. Also drops the
now-redundant
`combineCallbacks` workaround in `streamEvents`, which double-registered
and
    double-fired graph-bound callbacks.

fix(langgraph): preserve namespace nesting for imperative graph invokes

When a compiled graph is invoked from inside another graph's running
task
(e.g. a tool body calling `subAgent.invoke(...)`), the surrounding task
context — including the langgraph-internal nesting keys
(`__pregel_read`,
`__pregel_stream`, `checkpoint_ns`, the checkpoint map) — is propagated
    implicitly via `AsyncLocalStorage`. The base `Runnable.stream` calls
langchain-core's `ensureConfig`, which replaces the ambient
`configurable`
wholesale whenever the caller passes its own. Because `createAgent`
always
supplies a `configurable`, every tool-invoked sub-agent lost those keys,
ran
as a fresh root run, and had its streamed events flattened to the root
    namespace instead of nesting under the triggering task.

`Pregel.stream` now merges the ambient `configurable` underneath the
caller's
    (caller keys win per-key) when the ambient marks an active task
(`__pregel_read` present) but the explicit `configurable` is missing it.
Declared subgraph nodes (which already carry their own `__pregel_read`)
and
    top-level runs are unaffected.

fix(langgraph): dispatch stream messages handler inline

The v3 `messages` handler (`StreamProtocolMessagesHandler`, which powers
`run.messages`) only performs a synchronous `push()` onto the run's
stream, but
its callbacks were dispatched on LangChain's background callback queue
(the
default `awaitHandlers === false`). A model or tool call inside a nested
or
parallel task could therefore flush its `messages` chunk _after_ the
Pregel
loop returned and sealed the stream, where
`IterableReadableWritableStream.push`
silently drops chunks once closed. This surfaced as empty per-message
streams
(`sub.messages`) for subagents dispatched in parallel from a single
tools step.

The handler now sets `awaitHandlers = true` so its callbacks run inline
— every
push happens during the originating model/chain call while the stream is
still
open. This avoids the global over-wait, fake-timer deadlock, and
error-path
unhandled rejections that a blanket `awaitAllCallbacks()` drain before
close
    would have introduced.

fix(langgraph): support DeltaChannel fields in StateSchema

Add a `DeltaValue` state field (and a `MessagesDeltaValue` prebuilt) so
a
`DeltaChannel` can be declared via `StateSchema`, not just
`Annotation.Root` or
a raw channel map. `StateSchema` now maps `DeltaValue` to a
`DeltaChannel`
(forwarding `snapshotFrequency` and the value-schema default) and
validates its
    inputs/`Overwrite` updates like `ReducedValue`.

fix(sdk): avoid scoped stream resubscribe churn

Defer final projection disposal by one microtask so framework bindings
that release and immediately reacquire the same scoped projection during
reactive updates keep the existing stream subscription instead of
rotating through root-only and scoped SSE filters.

dependabot[bot] 7d8295dcca chore(deps): bump hono from 4.12.23 to 4.12.25 (#2548) 
Bumps [hono](https://github.com/honojs/hono) from 4.12.23 to 4.12.25.

<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/honojs/hono/releases">hono's
releases</a>.</em></p>
<blockquote>
<h2>v4.12.25</h2>
<h2>Security fixes</h2>
<p>This release includes fixes for the following security issues:</p>
<h3>CORS Middleware reflects any Origin with credentials when
<code>origin</code> defaults to the wildcard</h3>
<p>Affects: <code>hono/cors</code>. Fixes the wildcard origin reflecting
the request <code>Origin</code> and sending
<code>Access-Control-Allow-Credentials: true</code> when
<code>credentials: true</code> is set without an explicit
<code>origin</code>, where any site a logged-in user visited could make
credentialed cross-origin requests and read responses from
cookie-authenticated endpoints. GHSA-88fw-hqm2-52qc</p>
<h3>Body Limit Middleware can be bypassed on AWS Lambda by understating
<code>Content-Length</code></h3>
<p>Affects: <code>hono/body-limit</code> on AWS Lambda
(<code>hono/aws-lambda</code>, <code>hono/lambda-edge</code>). Fixes the
request being built with the client-declared <code>Content-Length</code>
while the body is delivered fully buffered, where a client could declare
a small <code>Content-Length</code> with a much larger body and slip
past the configured size limit. GHSA-rv63-4mwf-qqc2</p>
<h3>Path traversal in <code>serve-static</code> on Windows via encoded
backslash (<code>%5C</code>)</h3>
<p>Affects: <code>serveStatic</code> on Windows (Node, Bun, Deno
adapters). Fixes the path guard allowing a lone backslash, where an
encoded backslash (<code>%5C</code>) decoded to <code>\</code> was
treated as a separator by the Windows path resolver, letting a single
URL segment escape into a middleware-guarded subtree.
GHSA-wwfh-h76j-fc44</p>
<h3>AWS Lambda adapter merges multiple <code>Set-Cookie</code> headers
into one value, dropping cookies on ALB single-header and Lattice</h3>
<p>Affects: <code>hono/aws-lambda</code>. Fixes multiple
<code>Set-Cookie</code> response headers being joined into one
comma-separated value for ALB single-header responses and VPC Lattice
v2, where the value could not be split back into individual cookies and
clients silently dropped or misparsed them. GHSA-j6c9-x7qj-28xf</p>
<h3>Lambda@Edge adapter keeps only the last value of a repeated request
header, dropping the rest</h3>
<p>Affects: <code>hono/lambda-edge</code>. Fixes repeated request
headers being written with overwrite instead of append, where only the
last value of a header such as <code>X-Forwarded-For</code> reached the
application and the remaining values were silently dropped.

chore(deps): remove uuid dependency in favor of embedded uuid in core

Replace direct `uuid` package imports with `@langchain/core/utils/uuid`
across
langgraph packages to deduplicate dependencies and align with
@langchain/core's
    embedded UUID utilities.

## @langchain/langgraph-checkpoint-redis@1.0.9

Thanks [@lhlyu](https://github.com/lhlyu)! - Fix Redis checkpoint
pending write deserialization when a write document has no `value`
field. RedisJSON omits `undefined` values, so `loadPendingWrites` now
restores a missing `value` as `undefined` instead of passing it through
JSON parsing.

fix(sdk): reconnect SSE streams when heartbeat idle is detected

Detect half-open SSE connections by watching for server keep-alive
heartbeats (`: heartbeat`) and reconnecting with Last-Event-ID or
`since` when they stop. `"auto"` mode arms only after heartbeats are
observed, so long tool calls and HITL pauses do not false-fire on
heartbeat-emitting servers.

- [#2528](https://github.com/langchain-ai/langgraphjs/pull/2528)
[`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Allow custom `AgentServerAdapter`s to be late-bound and re-bound to a
thread. Adapters can now implement an optional `setThreadId(threadId)`,
which `client.threads.stream(threadId, { transport })` calls when
binding the active thread — including the lazily-minted id from the
first `submit()` on a `threadId: null` controller. The built-in
`ProtocolSseTransportAdapter`, `ProtocolWebSocketTransportAdapter`, and
`HttpAgentServerAdapter` implement it: `threadId` is now optional at
construction, request URLs derive from the currently-bound thread, and
`paths` entries may be functions of the thread id (`(threadId) =>
string`). This lets a single custom transport back a lazy
thread-creation flow instead of being pinned to one thread at
construction.

Christian Bromann e7e8035fad fix(sdk): late-bind threadId on custom AgentServerAdapter transports (#2528) 
## Summary
- Add optional `setThreadId(threadId)` to `TransportAdapter` and call it
from `client.threads.stream` when binding a custom adapter to the active
thread (including the id minted on the first `submit()` of a `threadId:
null` stream).
- Make `threadId` optional at construction on
`ProtocolSseTransportAdapter`, `ProtocolWebSocketTransportAdapter`, and
`HttpAgentServerAdapter`; derive command/stream/state URLs from the
currently-bound thread and allow `paths` entries to be `(threadId) =>
string`.
- Add unit tests for lazy binding, re-binding, function paths, and
`client.threads.stream` wiring.
- Document lazy thread binding for custom backends in core SDK and
framework docs (React, Vue, Svelte, Angular).

# Releases
## @langchain/langgraph-supervisor@1.1.0

### Minor Changes

- [#2521](https://github.com/langchain-ai/langgraphjs/pull/2521)
[`56682a6`](https://github.com/langchain-ai/langgraphjs/commit/56682a69a24d0dfb210f1fb5187c51e3adc356bf)
Thanks [@open-swe](https://github.com/apps/open-swe)! -
feat(langgraph-supervisor): Add `addHandoffMessages` to
`createSupervisor` and `createHandoffTool`, allowing supervisor-to-agent
handoff bookkeeping messages to be omitted from the expert agent's
message history. When `addHandoffBackMessages` is not provided, it now
defaults to the same value as `addHandoffMessages`, matching the Python
package behavior.

`createHandoffTool` now also accepts `description` as the preferred
option name while continuing to support the existing `agentDescription`
option as deprecated for backwards compatibility.

### Patch Changes

[`59d4765`](https://github.com/langchain-ai/langgraphjs/commit/59d4765870bc0cddf3ef594b128ab3280533cb6c)
Thanks [@pragnyanramtha](https://github.com/pragnyanramtha)! - Normalize
all whitespace in supervisor handoff tool names.

## @langchain/langgraph@1.4.1

### Patch Changes

- [#2520](https://github.com/langchain-ai/langgraphjs/pull/2520)
[`2da5c33`](https://github.com/langchain-ai/langgraphjs/commit/2da5c3374f7b91ba0afa607c507e2ff1591baca7)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(state): validate Zod state updates from nodes

Validate node return values and Command updates against Zod state schema
    constraints before applying them to graph state.

Fixes [#2519](https://github.com/langchain-ai/langgraphjs/issues/2519)

- [#2511](https://github.com/langchain-ai/langgraphjs/pull/2511)
[`ef04db3`](https://github.com/langchain-ai/langgraphjs/commit/ef04db316d680ab32b812c88cadda75638294dd3)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
feat(ToolNode): forward graph state to tools via `runtime.state`

`ToolNode` now forwards its input to each tool through the second
argument as `runtime.state`. When using `ToolNode` as a node in a
LangGraph graph, this gives tools access to the current graph state for
workflows that need tool-call support in LangGraph proper. Tools can
type the second parameter as `ToolRuntime<StateType>` from
`@langchain/core/tools` and read `runtime.state` directly. This works in
every runtime, including web browsers, and removes the need for
`getCurrentTaskInput()` (which relies on
`node:async_hooks`/`AsyncLocalStorage`). `getCurrentTaskInput(config)`
continues to work for backwards compatibility.

Thanks [@christian-bromann](https://github.com/christian-bromann)! -
feat(stream): add per-event side-effect selector

Add `useChannelEffect` (React/Svelte/Vue) / `injectChannelEffect`
(Angular), a side-effect counterpart to `useChannel` that invokes an
`onEvent` callback once per raw protocol event without re-rendering.
This is the idiomatic v1 replacement for the old `onLangChainEvent` /
`onCustomEvent` callbacks for analytics and logging. Backed by a new
framework-agnostic `acquireChannelEffect` helper in
`@langchain/langgraph-sdk/stream` that shares a ref-counted subscription
with matching `useChannel` consumers.

[`7c3e9e9`](https://github.com/langchain-ai/langgraphjs/commit/7c3e9e93f3c7ec1dc654dac8ee8c03562ee8337b)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(sdk): stop re-streaming seeded messages on idle-thread submit

An idle (finished) thread defers its root SSE pump, so the first
`submit()` brings it up and the transport replays the finished run from
`seq=0`. The replayed `messages` channel carries no step (unlike
`values`, guarded by `maxStep`), so it rebuilt each already-complete
message from an empty `message-start` and re-streamed the whole turn
token-by-token — a visible "messages replay" of the existing
conversation. Seal the message ids seeded from the idle `getState()`
snapshot so replayed deltas can't downgrade the complete tail; the seal
lifts once a newer checkpoint advances the timeline or on thread rebind,
and ids from the next run are never sealed.

Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(sdk): reconnect v2 SSE and WebSocket thread streams after disconnect

Add automatic reconnect with resume (`since` for SSE) for protocol
transports,
wire `AsyncCaller` through `client.threads.stream`, and expose optional
reconnect tuning on `ThreadStreamOptions`. Includes integration tests
against
    an in-process mock langgraph-api server.

Christian Bromann 3855985dd0 fix(sdk): add per-event channel effect selector (#2522) 
## Summary
- Add a side-effect counterpart to `useChannel`: `useChannelEffect`
(React, Svelte, Vue) and `injectChannelEffect` (Angular). It invokes an
`onEvent` callback once per raw protocol event and returns nothing, so
it never re-renders — the idiomatic v1 replacement for the removed
`onLangChainEvent` / `onCustomEvent` callbacks used for
analytics/logging.
- Back all four bindings with a new framework-agnostic
`acquireChannelEffect(registry, channels, namespace, options)` helper in
`@langchain/langgraph-sdk/stream`. It acquires the same ref-counted
`channelProjection` as `useChannel` (so an effect consumer and a
matching `useChannel` share one server subscription and survive thread
swaps), diffs the shared store by event identity, skips events buffered
before it attaches (no double-counting history on a late mount), and
resets correctly across thread rebinds.
- API matches the agreed shape with `target`, `enabled`, `replay`
(defaults to `false`/live-only — opposite of `useChannel`),
`bufferSize`, `onEvent`, and `onError`. Callbacks are read from a
ref/lazy wrapper so fresh inline closures never re-subscribe.
- Update selector docs and `v1-migration.md` in all four SDKs, noting
the callback now receives v1 protocol events (`lifecycle.*`, `tools.*`,
`messages.*`, `custom`) rather than legacy LangChain event names.

[`a8e7659`](https://github.com/langchain-ai/langgraphjs/commit/a8e7659a9d22fd84425aaf26bda88667c76b185a)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
`DeltaChannel` and the writes-history saver API (beta).

`DeltaChannel` is a reducer channel that stores only a sentinel in
checkpoint
blobs instead of the full accumulated value, reconstructing state on
read by
replaying ancestor writes through a batch reducer. This avoids
re-serializing
the entire accumulated value at every step (e.g. long message
histories).

- `DeltaChannel(reducer, { snapshotFrequency })` in
`@langchain/langgraph` —
count-based snapshot cadence (default `snapshotFrequency=1000`) plus a
system bound `DELTA_MAX_SUPERSTEPS_SINCE_SNAPSHOT` (default 5000, env
        `LANGGRAPH_DELTA_MAX_SUPERSTEPS_SINCE_SNAPSHOT`).
- `messagesDeltaReducer` — a batching-invariant messages reducer that
coerces
        raw object/string writes, for use with `DeltaChannel`.
- `BaseCheckpointSaver.getDeltaChannelHistory({ config, channels })`
(beta) —
walks the parent chain returning per-channel `{ writes, seed? }`, with a
        direct-storage override in `MemorySaver`.
- `counters_since_delta_snapshot` added to `CheckpointMetadata`;
`DeltaSnapshot`
        serialization support in the JSON+ serializer.

Reconstruction is wired through the Pregel read/execution paths
(initialization,
`getState`, `updateState`, local reads) and `exit` durability
accumulates and
anchors delta writes so threads remain reconstructible without forcing
    snapshots.

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
node-level timeouts.

A `timeout` option is now supported on `StateGraph.addNode`, the
functional API
(`task`/`entrypoint`), and the `Send` constructor. Pass a number of
milliseconds
    for a hard wall-clock cap, or a `TimeoutPolicy` for finer control:

    ```ts
    import { TimeoutPolicy } from "@langchain/langgraph";

    // hard wall-clock cap on each attempt
    builder.addNode("agent", agentFn, { timeout: 60_000 });

    // full control
    builder.addNode("agent", agentFn, {
      timeout: {
        runTimeout: 60_000, // hard wall-clock cap, never refreshed
        idleTimeout: 10_000, // cap on time without observable progress
        refreshOn: "auto", // "auto" | "heartbeat"
      },
    });

    // per-task override
    new Send("agent", state, { timeout: { idleTimeout: 5_000 } });
    ```

    When a timeout fires, a `NodeTimeoutError` (carrying `node`, `kind`
(`"run"`/`"idle"`), `timeout`, `elapsed`, `runTimeout`, `idleTimeout`)
is raised,
the attempt's buffered writes are dropped, and the node's `AbortSignal`
is
aborted. `idleTimeout` is refreshed by observable progress (writes,
custom
stream-writer calls, child-task scheduling, callback events) or an
explicit
    `runtime.heartbeat()` call. The timer resets per retry attempt, and
    `NodeTimeoutError` is retryable under the default retry policy.

### Minor Changes

[`d12d269`](https://github.com/langchain-ai/langgraphjs/commit/d12d2693308e37951266bc8197daa656daa6e2aa)
Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
cooperative, between-superstep graph draining via `RunControl`.

    A new `RunControl` (exported from `@langchain/langgraph`) exposes
`requestDrain(reason)` plus read-only `drainRequested` / `drainReason`.
Pass it
through the new `control` option on `invoke` / `stream` / `streamEvents`
(and the
functional API). It is surfaced on `runtime.control`, so nodes can read
it or call
    `requestDrain()` themselves, and it is propagated into subgraphs.

When a drain is requested, the Pregel loop checks the flag at the top of
each
superstep (after the previous step's writes are applied and
checkpointed): if more
tasks remain it saves the checkpoint and throws the new `GraphDrained`
error (also
under `durability: "exit"`), so the run can be resumed later from the
same config.
If the graph naturally finishes on that tick it returns normally and the
caller can
inspect `control.drainRequested`. A drain requested inside a subgraph
bubbles up and
stops the parent at its next boundary. Draining never cancels work that
is already
running — pair it with an `AbortSignal` if you need a hard upper bound.

feat(langgraph): add node-level error handlers

`StateGraph.addNode(name, fn, { errorHandler })` now accepts a
first-class
node-level error handler. The handler runs ONLY after the failing node's
`retryPolicy` is exhausted, so retry and handling stay decoupled. It
receives a
typed `NodeError { node, error }` and the typed node input state, can
return a
state update, and can route to a recovery branch via `new Command({ goto
})`
    (saga / compensation flows).

Failure provenance is checkpointed (via a reserved `ERROR_SOURCE_NODE`
write) so
handlers observe the same context after a checkpoint resume. Uncaught
node
errors without a handler still abort the run as before, and
`GraphBubbleUp`
    errors (such as `interrupt()`) are never swallowed by a handler.

`StateGraph.setNodeDefaults({ errorHandler })` now also accepts a
graph-wide
default handler. It is materialized at `compile()` as a single shared
handler
and invoked for every regular node that does not set its own
`errorHandler`. A
per-node handler always takes precedence, the default never catches a
failure
raised by an error-handler node itself (handler failures fail the run),
and the
    default is not inherited by subgraphs.

    Ports the Python feature from langchain-ai/langgraph#7233.

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
`StateGraph.setNodeDefaults()` for setting graph-wide node policy
defaults (`retryPolicy`, `cachePolicy`). Per-node values passed to
`addNode` always take precedence, and defaults are resolved at
`compile()` time so call order does not matter. Defaults are not
inherited by subgraphs. Ports Python's `set_node_defaults()`
(langchain-ai/langgraph#7747).

a mixed `putWrites([[...regular...], [INTERRUPT, …]], taskId)` placed
the INTERRUPT at a positive idx that could collide with a regular write
at the same `(task_id, idx)`, and the unconditional `$set` upsert
silently overwrote whichever row landed there first. The
conflict-resolution clause now matches the Postgres / SQLite (TS and
Python) checkpointers: `$set` only when every channel is a special one,
`$setOnInsert` otherwise.

Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix: reject SQL
`LIKE` wildcards (`%`, `_`) and the backslash escape character in
`PostgresStore` namespace labels. `BaseStore.search()` matches
namespaces via `namespace_path LIKE ${prefix}%`, and these characters in
caller-supplied namespace labels are interpreted as wildcards by
Postgres even through a bound parameter — letting a namespace prefix of
`["%"]` match every namespace in the store across tenants.
`validateNamespace` now throws for these characters at all `search` /
`get` / `put` entrypoints, keeping store-wide consistency. CWE-1336.

`RedisSaver.putWrites` now honors `WRITES_IDX_MAP`, pinning special
channels (`__error__`, `__scheduled__`, `__interrupt__`, `__resume__`)
to fixed negative indices in their Redis key
(`checkpoint_write:…:<idx>`) instead of the call-local ordinal.
Previously a mixed `putWrites([[…regular…], [INTERRUPT, …]], taskId)`
placed the INTERRUPT key at the positive idx of its position in the
batch, where a peer task's regular write at the same idx would overwrite
it via the unconditional `JSON.SET`. The conflict-resolution clause now
matches Postgres / SQLite / MongoDB: unguarded `JSON.SET` when every
write is a special channel, `JSON.SET … NX` (insert-or-ignore)

checkpoint silently `REPLACE`d the regular write previously stored at
`idx=0` for that task, losing data. The conflict-resolution clause also

Christian Bromann 49b8c1a04c fix: make AnyStream a true supertype so selector hooks need no cast (#2515) 
## Summary
- `AnyStream` (`UseStreamReturn<any, any, any>`) was not actually a
supertype of concrete stream handles: members computed from the generics
in covariant positions don't collapse under `any`. `toolCalls` resolves
via `InferToolCalls<any>` to `AssembledToolCall<string, …, never>[]`,
whose `never` output slot is narrower than a concrete handle's
`unknown`, so `UseStreamReturn<typeof agent>` failed to assign and every
`useMessages`/`useToolCalls`/`useValues` (`inject*` on Angular) call
required an `as AnyStream` cast.
- Redefined `AnyStream` in all four framework packages to `Omit` the
generic-computed members and re-add them at their widest forms,
preserving each framework's reactivity wrapper: plain arrays for
React/Svelte, `Readonly<ShallowRef<…>>` for Vue, `Signal<…>` for
Angular. React also drops `~stateType` (the only package that has that
member).
- Retyped each package's internal `getRegistry` to accept `AnyStream`,
removed React's duplicate local `AnyStream` in `selectors.ts` in favor
of the public type, and corrected the misleading doc comments.
- Downstream (`langchainplus` agent-chat-v2) can drop its `stream as
AnyStream` casts once these ship.

Christian Bromann 41cd05a411 fix(sdk): hydrate custom transport without extra client config (#2508) 
## Summary
- `StreamController.hydrate()` calls `transport.getState()` when the
adapter implements it, then falls back to `client.threads.getState()`.
- `HttpAgentServerAdapter` / `ProtocolSseTransportAdapter` add
`getState()` via `GET /threads/:threadId/state` (optional `paths.state`
override).
- `resolveClientApiUrl()` lets `useStream` build the hydration `Client`
from the transport’s `apiUrl` when none is passed explicitly.
- React, Vue, and Angular `useStream` hooks use the resolver so
custom-backend apps only need `transport={adapter}`.

Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Consolidate the protocol session's channel inference, channel-set
validation, and namespace prefix matching onto the shared
`@langchain/langgraph/stream` helpers instead of maintaining local
copies. This removes duplicated logic across `session/index.mts`,
`session/namespace.mts`, `session/internal-types.mts`, and
`service.mts`.

This also aligns SSE event-sink filtering (`matchesSinkFilter`) with the
WebSocket subscription matcher: both now normalize dynamic namespace
suffixes (e.g. a `["fetcher"]` namespace filter matches an event emitted
under `["fetcher:<uuid>"]`). Previously the SSE path used a stricter
exact-segment match.

Because the session now imports `@langchain/langgraph/stream`, the
`@langchain/langgraph` peer dependency floor is raised to `^1.3.6` (the
first release that ships the `/stream` entrypoint).

`SqliteSaver.list({}, { filter })` now honors arbitrary metadata keys

Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add
the `@langchain/langgraph/stream` entrypoint — a transport-agnostic
backend toolkit for building custom servers on top of the v2 streaming
protocol. Alongside the existing `StreamChannel` and
`convertToProtocolEvent`, it exposes subscription primitives, typed
against a minimal `MatchableEvent` shape so they work on both the core
`ProtocolEvent` and the wire-level `Event` from `@langchain/protocol`:

- `inferChannel(event)` — map an event to its subscription `Channel`
(named `custom:<name>` channels included).
- `matchesSubscription(event, definition)` — decide whether a buffered
event should be delivered for a `SubscribeParams` filter, honoring
channel, namespace prefix/depth, and an optional `since` replay cursor.
- `isPrefixMatch(namespace, prefix)` /
`normalizeNamespaceSegment(segment)` — namespace prefix matching with
dynamic-suffix normalization (e.g. `fetcher:<uuid>` matches the
`fetcher` prefix).
- `SUPPORTED_CHANNELS` / `isSupportedChannel(value)` — the recognized
channel set and a guard for validating subscription requests.

Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Deduplicate the client stream transports: the protocol transport now
shares the SSE decoder and `IterableReadableStream` helpers with the
legacy transport instead of carrying its own copies. Removes the
redundant `transport/decoder.ts` and `transport/stream.ts` shims (and a
dead `StreamPart` re-export), importing the shared utilities from
`utils/sse.ts` directly. No public API or behavior change.

Christian Bromann f67772ff3f fix(sdk): resume useChannel subscriptions across serial runs (#2500) 
## Summary
- Fix `channelProjection` to pass `resumeOnPause: true`, matching
`extensionProjection`, so `useChannel` continues receiving events after
each run's terminal lifecycle event instead of going silent after the
first prompt on a thread.
- Add a unit test that simulates a paused subscription resuming with a
second event batch, and a React browser integration test asserting
`useChannel` event count grows across two serial submits (3 → 6).
- Update selector JSDoc and `selectors.md` / `selector-composables.md`
across React, Vue, Svelte, and Angular to document the complementary
roles: `useChannel` = full bounded event history across runs;
`useExtension` = latest payload only.

fix(langgraph): forward named custom stream channels consistently

Forward remote `StreamChannel` emissions as `custom:<name>` protocol
events and normalize them back to custom-channel payloads in the API
session. This aligns JavaScript stream-channel forwarding with the
protocol subscription shape used by remote clients, so `custom:<name>`
subscriptions receive extension channel data consistently.

Coalesce concurrent identical `threads.getState()` and

do not issue duplicate hydrate requests. Request identity includes the
prepared URL, body, method, and headers, and coalescing is skipped for
caller-provided abort signals, raw response reads, and `onRequest` hooks
to preserve auth and cancellation isolation.

fix(sdk): reconcile subagents and subgraphs on thread reconnect

Seed deep-agent subagent cards from checkpoint messages and subgraph
hosts from a single bounded `getHistory` read during `hydrate()`, so
parallel fan-out discovery reappears immediately on refresh instead of
waiting for SSE replay. Subagent execution namespaces are promoted
through the existing guarded discovery state machine (bulk at hydrate,
lazily per opened card via the selector layer). The getHistory cost is
O(1) in requests regardless of fan-out width.

fix(sdk): revive automatic optimistic submit echo

Echo `submit()` input into `values` / `messages` immediately with
client-side
id minting and id-based reconciliation as the server streams back.
Expose
per-message `optimisticStatus` via message metadata (`pending` → `sent`
/
`failed`), shallow-merge non-message keys with rollback when no `values`
arrive, and add an `optimistic: false` hook opt-out. Plumb through
React,

Christian Bromann a9aa8d6a9b fix(sdk): reconcile subagents and subgraphs on thread reconnect (#2497) 
## Summary
- Subagent cards are seeded from checkpoint messages and subgraph hosts
from a single bounded `getHistory` during `hydrate()`, so reconnecting
to a thread restores parallel fan-out discovery immediately instead of
waiting for full SSE replay.
- Subagent execution namespaces are resolved from history through the
existing guarded discovery state machine — bulk-promoted at hydrate, and
lazily per opened card via a selector-layer trigger added to
React/Vue/Svelte/Angular.
- `getHistory` usage is bounded (one page + at most one `before`-cursor
fallback) and O(1) in requests regardless of how many
subagents/subgraphs ran in parallel.

dependabot[bot] f552c05813 chore(deps): bump hono from 4.12.18 to 4.12.21 (#2492) 
Bumps [hono](https://github.com/honojs/hono) from 4.12.18 to 4.12.21.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/honojs/hono/releases">hono's
releases</a>.</em></p>
<blockquote>
<h2>v4.12.21</h2>
<h2>Security fixes</h2>
<p>This release includes fixes for the following security issues:</p>
<h3>app.mount() strips mount prefix using undecoded path, causing
incorrect routing for percent-encoded paths</h3>
<p>Affects: <code>app.mount()</code>. Fixes prefix stripping using the
raw URL pathname instead of the decoded path, where percent-encoded
characters in the mount prefix or path could cause the prefix to be
removed at the wrong position, resulting in the sub-application
receiving an incorrect path. GHSA-2gcr-mfcq-wcc3</p>
<h3>IP Restriction bypasses static deny rules for non-canonical
IPv6</h3>
<p>Affects: <code>hono/ip-restriction</code>. Fixes IP address
comparison using string equality, where non-canonical IPv6
representations of a denied address — such as compressed forms or
hex-notation IPv4-mapped addresses — could bypass static deny rules.
GHSA-xrhx-7g5j-rcj5</p>
<h3>Cookie helper does not sanitize sameSite and priority, allowing
Set-Cookie injection</h3>
<p>Affects: <code>hono/cookie</code>. Fixes missing validation of
<code>sameSite</code> and <code>priority</code> options against
injection characters (<code>;</code>, <code>\r</code>, <code>\n</code>),
where user-controlled input passed to either option could inject
additional attributes into the Set-Cookie response header.
GHSA-3hrh-pfw6-9m5x</p>
<h3>JWT middleware accepts any Authorization scheme, not only
Bearer</h3>
<p>Affects: <code>hono/jwt</code>, <code>hono/jwk</code>. Fixes missing
scheme validation in the Authorization header, where any two-part header
value was accepted regardless of the scheme name, allowing non-Bearer
schemes to pass JWT authentication. GHSA-f577-qrjj-4474</p>
<hr />
<p>Users who use <code>app.mount()</code>,
<code>hono/ip-restriction</code>, <code>hono/cookie</code>, or
<code>hono/jwt</code>/<code>hono/jwk</code> are encouraged to upgrade to
this version.</p>

Christian Bromann 0a0e04e9ff fix(sdk): revive automatic optimistic submit echo (#2494) 
## Summary
- revive automatic optimistic updates to `@langchain/langgraph-sdk`:
`submit()` input is echoed into `values` / `messages` immediately,
messages without ids get client-minted ids for server reconciliation,
and non-message keys are shallow-merged with rollback when no `values`
snapshot arrives.
- Track per-message lifecycle via
`useMessageMetadata(...).optimisticStatus` (`pending` → `sent` /
`failed`); failed optimistic messages are kept for retry UX and dropped
on `hydrate()`.
- Plumb `optimistic?: boolean` through React, Vue, Svelte, and Angular
`useStream` hooks (defaults to enabled) and document the v1 migration
path replacing legacy `optimisticValues`.
- Add browser e2e tests across all four framework SDKs covering message
happy path, id reconciliation, failure handling, opt-out, and
non-message state convergence/rollback.

fix(core): keep stream chunks as three-element tuples

    Emit lightweight checkpoint envelopes as separate
`[namespace, "checkpoints", envelope]` chunks before paired `values`
chunks.
    Public `stream()` always yields `[namespace, mode, payload]`; the v3
    protocol path surfaces envelopes via `convertToProtocolEvent`.

fix(sdk): surface resumed run failures on stream.error

Route `respond()` and `respondAll()` through a coordinator dispatch path
that
writes the reactive `rootStore.error` slot when a resumed run reaches a
failed
terminal or when `input.respond` dispatch fails, matching submit()
behavior so
framework consumers (e.g. API-key retry UIs) observe resume failures via
    `stream.error` instead of only `isLoading` transitions.

feat(openrouter): surface reasoning content as v1 standard content
blocks</p>
<p><code>convertOpenRouterResponseToBaseMessage</code> and
<code>convertOpenRouterDeltaToBaseMessageChunk</code> now copy
OpenRouter's
<code>reasoning</code> (flat string) and <code>reasoning_details</code>
(structured array) fields
onto <code>additional_kwargs.reasoning_content</code> /
<code>additional_kwargs.reasoning_details</code>.
A new <code>ChatOpenRouterTranslator</code> is registered in
<code>@langchain/core</code> under
the <code>&quot;openrouter&quot;</code> provider key so
<code>AIMessage.contentBlocks</code> emits standard
<code>{type: &quot;reasoning&quot;}</code> blocks alongside text and
tool calls.</p>
<p>Previously, reasoning text returned by reasoning-capable models
routed
through OpenRouter (DeepSeek R1, Minimax M2, Claude extended thinking,
o-series, etc.) was silently dropped: only the
<code>reasoning_tokens</code> count
was preserved via <code>usage_metadata</code>. Consumers using standard
content blocks
(including the frontend agent UI patterns shown in the docs) could not
display the model's chain of thought.</p>

fix(langchain/createAgent): throw on terminal
<code>providerStrategy</code> parse failure instead of silently
resolving with <code>structuredResponse: undefined</code></p>
<p>When <code>createAgent</code> was configured with
<code>responseFormat</code> resolving to a <code>providerStrategy</code>
(either passed explicitly or auto-promoted from a bare Zod / JSON schema
for models whose profile reports <code>structuredOutput: true</code>),
and the model produced a terminal response (no <code>tool_calls</code>)
whose text could not be JSON-parsed or did not satisfy the schema, the
agent silently exited with no <code>structuredResponse</code>, surfacing
later as <code>TypeError: Cannot read properties of undefined</code>.
The agent now throws a <code>StructuredOutputParsingError</code> in that
case while still allowing the agent loop to continue when tool calls are
present. Closes <a

fix(openai): guard bare <code>JSON.parse</code> in Responses API
converter against trailing non-whitespace characters</p>
<p><code>convertResponsesDeltaToChatGenerationChunk</code> previously
called <code>JSON.parse(msg.text)</code> directly when
<code>response.text.format.type === &quot;json_schema&quot;</code>. Some
models (observed with <code>gpt-5-mini</code> on <code>service_tier:
&quot;auto&quot;</code>) intermittently emit trailing non-whitespace
characters (extra tokens, control characters) after a valid JSON object,
causing a <code>SyntaxError</code> that propagates as an unhandled
exception and kills the entire streaming response mid-flight. The parse
is now wrapped in a <code>try</code>/<code>catch</code>: on failure,
<code>additional_kwargs.parsed</code> is left undefined, the stream
completes normally, and the existing <code>withStructuredOutput</code>
pipeline handles the typed failure — <code>includeRaw: true</code>
returns <code>{ raw, parsed: null }</code> via its
<code>withFallbacks</code> wrapper, <code>includeRaw: false</code>
throws a typed <code>OutputParserException</code> that the caller can
catch and retry. Closes <a

fix(sdk): claim in-flight slot before root pump wait for enqueue

Move `#runAbort` and `isLoading` setup ahead of `waitForRootPumpReady()`
so
`multitaskStrategy: "enqueue"` submits in the same tick land in
`queueStore`
    instead of bypassing the client queue.

## @langchain/langgraph-sdk@1.9.14

### Patch Changes

- [#2482](https://github.com/langchain-ai/langgraphjs/pull/2482)
[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)

fix(sdk): keep subgraph status complete when values arrives late

    `SubgraphDiscovery` no longer downgrades a terminal subgraph back to
`running` when a host-namespace `values` snapshot is observed after its
`completed` or `failed` lifecycle event. The content pump and lifecycle
watcher are independent streams, so this reordering could strand nodes
as
    perpetually running in `useStream` subgraph UIs.

fix(sdk): normalize HITL edit decisions for Python servers

`StreamController.respond()` now mirrors camelCase and snake_case on
edit
decisions (`editedAction` / `edited_action`) so JS clients can resume
    human-in-the-loop interrupts against Python LangGraph servers.

fix(sdk): route headless tool resumes through respond on v1 stream

`useStream` was calling `submit(null, { command })` for headless-tool
resumes,
    which dispatches `run.start` without delivering the tool result. Add
`applyHeadlessToolResumeCommand` to route payloads through `respond` /
`respondAll`, and tighten headless-tool browser tests to assert
end-to-end
    resume and graph completion.

Christian Bromann 0491534712 fix(sdk): route headless tool resumes through respond on v1 stream (#2467) 
## Summary

- Fix headless-tool resume on the v1 stream protocol by routing resume
payloads through `applyHeadlessToolResumeCommand` (`respond` /
`respondAll`) instead of `submit(null, { command })`.
- Export `applyHeadlessToolResumeCommand` and
`HeadlessToolResumeController` from `@langchain/langgraph-sdk` and
re-export from `@langchain/react`.
- Strengthen headless-tool browser tests across React, Vue, Angular, and
Svelte to assert tool result values, final agent message, idle loading
state, and no lingering interrupts.

## @langchain/langgraph-checkpoint@1.0.4

### Patch Changes

- [#2344](https://github.com/langchain-ai/langgraphjs/pull/2344)
[`0125920`](https://github.com/langchain-ai/langgraphjs/commit/0125920a2c4a87dc1d66aaf541ea16146f8cf842)
Thanks [@dependabot](https://github.com/apps/dependabot)! - chore(deps):
bump uuid to 14.0.0 and keep checkpoint ID ordering stable

Bump `uuid` from 10.x/13.x to 14.0.0 across packages. Starting with uuid
11, `v6({ clockseq })` no longer advances the sub-millisecond time
counter when an explicit `clockseq` is passed, so checkpoint IDs created
within the same millisecond were ordered only by `clockseq`. Since
checkpoint IDs are sorted lexicographically, this broke ordering — most
visibly for the negative `clockseq` used by the first ("input")
checkpoint, which sorted as the newest.

`uuid6()` now maintains its own monotonic `(msecs, nsecs)` clock
(mirroring uuid 10's internal v1 behavior) so the time component is
always strictly increasing and checkpoint ordering no longer depends on
the `clockseq` value. `emptyCheckpoint()` also uses a non-negative
`clockseq`.

bump uuid to 14.0.0 and keep checkpoint ID ordering stable

Bump `uuid` from 10.x/13.x to 14.0.0 across packages. Starting with uuid
11, `v6({ clockseq })` no longer advances the sub-millisecond time
counter when an explicit `clockseq` is passed, so checkpoint IDs created
within the same millisecond were ordered only by `clockseq`. Since
checkpoint IDs are sorted lexicographically, this broke ordering — most
visibly for the negative `clockseq` used by the first ("input")
checkpoint, which sorted as the newest.

`uuid6()` now maintains its own monotonic `(msecs, nsecs)` clock
(mirroring uuid 10's internal v1 behavior) so the time component is
always strictly increasing and checkpoint ordering no longer depends on
the `clockseq` value. `emptyCheckpoint()` also uses a non-negative
`clockseq`.

fix(langgraph-checkpoint): block prototype pollution in MemorySaver via
reserved storage keys

    `MemorySaver` previously embedded `thread_id`, `checkpoint_ns`,
`checkpoint_id`, and `task_id` directly into property accesses on the
nested plain objects `this.storage` and `this.writes`. A caller able to
shape any of those fields (every quickstart, tutorial, and test fixture
    uses `MemorySaver` by default) could pass `"__proto__"`,
    `"constructor"`, or `"prototype"` and have the subsequent assignment
    mutate `Object.prototype`. From that point every plain object in the
    process inherits the injected property, breaking `for...in` loops,
truthy short-circuits, and downstream serializers across unrelated code
    paths. CWE-1321.

Adds an `assertSafeStorageKey` chokepoint applied at every public entry
that touches `storage` or `writes` (`put`, `putWrites`, `deleteThread`,
    `getTuple`, `list`). The guard rejects non-string values, the empty
string (unless explicitly opted-in for `checkpoint_ns`), and the three
    prototype-pollution keys. Behaviour for valid string identifiers is
    unchanged.

fix(checkpoint-redis): block Redis KEYS / SCAN pattern injection via
top-level identifiers

`RedisSaver` and `ShallowRedisSaver` previously embedded `thread_id`,
`checkpoint_ns`, `checkpoint_id`, and `task_id` directly into Redis keys
and `client.keys(pattern)` calls with no validation. A caller able to
    shape any of those fields (multi-tenant SDK deployments where the
`RunnableConfig` originates from request input, or webhook payloads that
flow into a persisted thread) could promote a string identifier into a
    glob pattern (`*`, `?`, `[...]`) or escape character (`\`).

    The most severe sink is `deleteThread`: a `threadId` of `*` issues
`client.keys("checkpoint:*:*")` followed by `client.del(...)`, deleting
    every checkpoint in the database across every tenant. `getTuple`,
    `list`, and `loadPendingWrites` are exposed to the same pattern via
the fallback paths that bypass the existing `escapeRediSearchTagValue`
    defense.

    Adds a single `assertSafeKeyComponent` helper exported from
    `./utils.js` and applies it at every key-building site. The guard
    asserts the value is a non-empty string (the empty `checkpoint_ns`
    default is opt-in via `{ allowEmpty: true }`) and rejects the Redis
pattern meta-characters `* ? [ ] \`. The `:` delimiter is intentionally
    permitted because LangGraph emits it as a legitimate part of
    `checkpoint_ns` for subgraphs / nested graphs, where it only ever
appears as a literal in the key. Behavior for valid string identifiers
    is unchanged.

protocol-v2: fold forkFrom client-side and honor per-run
multitaskStrategy

    The SDK now folds the ergonomic `forkFrom` option into
`config.configurable.checkpoint_id` before sending `run.start`, so the
agent server only ever accepts the single, legacy-compliant fork field
(`forkFrom` no longer hits the wire). The protocol-v2 reference servers
    drop their top-level `forkFrom` normalization accordingly.

The protocol-v2 servers now honor the caller's `multitaskStrategy` per
run (one of `reject` \| `rollback` \| `interrupt` \| `enqueue`) instead
of
hardcoding it, falling back to `enqueue` when omitted or unrecognized.

The stream controller (and the React/Angular/Svelte/Vue wrappers) gain a
`respondAll(responsesById, options)` method to resume several interrupts
pending at the same checkpoint in a single command — required for runs
that
pause on multiple interrupts at once (e.g. parallel tool-authorization
      prompts), which sequential `respond()` calls cannot handle.

`respond()` now takes an options object (`{ interruptId?, namespace?,
config?, metadata? }`) so a resumed run can carry the same run-level
config
(model, user context, …) and metadata (trigger source, test flags, …) a
fresh `submit()` would. The protocol-v2 reference servers read the new
`responses` batch and `config` / `metadata` fields leniently and fold
them
      onto the run that services the `input.respond` command.

protocol-v2: fold forkFrom client-side and honor per-run
multitaskStrategy

    The SDK now folds the ergonomic `forkFrom` option into
`config.configurable.checkpoint_id` before sending `run.start`, so the
agent server only ever accepts the single, legacy-compliant fork field
(`forkFrom` no longer hits the wire). The protocol-v2 reference servers
    drop their top-level `forkFrom` normalization accordingly.

The protocol-v2 servers now honor the caller's `multitaskStrategy` per
run (one of `reject` \| `rollback` \| `interrupt` \| `enqueue`) instead
of
hardcoding it, falling back to `enqueue` when omitted or unrecognized.

Christian Bromann 2c14b12a80 fix(sdk): add back respondAll and respond config/metadata (#2448) 
## Summary
- Add `respondAll(responsesById, options)` to the stream controller and
the React/Angular/Svelte/Vue wrappers, resuming multiple interrupts
pending at the same checkpoint in a single `Command({ resume })`. This
is required for runs that pause on several interrupts at once (e.g.
parallel tool-authorization prompts), which sequential `respond()` calls
cannot service.
- Change `respond()` to take an options object (`{ interruptId?,
namespace?, config?, metadata? }`), folding run-level
`config`/`metadata` onto the resumed run so it applies the same
configurable values and metadata a fresh `submit()` would.
- Extend `ThreadStream.respondInput()` to accept a `responses` batch
(mutually exclusive with the single `interrupt_id`/`response`) and clear
all responded interrupts from local state.
- Update the protocol-v2 reference servers (`embed/protocol.mts`,
`protocol/service.mts`) to read the `responses` batch plus
`config`/`metadata` leniently and fold them onto the run servicing
`input.respond`.
- Update docs (interrupts/use-stream) across all framework packages and
add controller tests for batched resume.

Christian Bromann 80a8c1200a refactor(sdk): drop StreamSubmitOptions.command and simplify forkFrom (#2443) 
## Summary
- Remove `command` from `StreamSubmitOptions` and the
`submit-coordinator` resume-via-`submit` path so HITL resume goes
through `stream.respond()` only.
- Simplify `forkFrom` from `{ checkpointId: string }` to a plain
checkpoint id string across the SDK, protocol-v2 services, and docs.
- Update interrupt tests, examples (`HumanInTheLoopView`, branching
views), and React/Vue/Svelte/Angular JSDoc and migration/interrupt docs
to match.

fix(sdk): cancel runs on stop by default and add disconnect()

`stream.stop()` now calls `client.runs.cancel` for the active run before
disconnecting the client (default `{ cancel: true }`). Join/rejoin UIs
can call `stream.disconnect()` or `stop({ cancel: false })` to leave the
agent running server-side.

    This fills a missing gap we found when migrating to v1.

Christian Bromann 29d2bde235 fix(sdk): cancel runs on stop by default and add disconnect() (#2438) 
## Summary

- `stream.stop()` now cancels the active run server-side by default
(`client.runs.cancel`) before disconnecting the client transport.
- Added `stream.disconnect()` as an alias for `stop({ cancel: false })`
for join/rejoin UIs.
- Introduced `StreamStopOptions` (`{ cancel?: boolean }`) on
`StreamController` and all v1 framework bindings (React, Vue, Svelte,
Angular).
- Updated `use-stream.md` and added controller unit tests for
cancel-on-stop and no-cancel-on-disconnect.

Christian Bromann f99941f5fe fix(sdk): clear subgraph and subagent discovery on thread swap (#2430) 
## Summary
- Add `reset()` to `SubgraphDiscovery` and `SubagentDiscovery` to clear
internal maps and committed store snapshots.
- Call both resets from `StreamController.#teardownThread()` alongside
existing per-thread resets (messages, tools, metadata).
- Add unit tests for discovery `reset()` and a controller test that
`hydrate(null)` clears subgraphs after lifecycle events.

Christian Bromann 3529e3831a fix(sdk): align AssembledToolCall typing with pre-v1 expectations (#2421) 
## Summary
- Split tool-call handles by consumer:
- **Client SDK** (`ThreadStream.toolCalls`, subgraph/subagent
projections): `ClientAssembledToolCall` with a promise-only `output`
(resolves on success, rejects on error). Still exported as
`AssembledToolCall` from `@langchain/langgraph-sdk/client` for script
usage.
- **Framework SDKs** (`stream.toolCalls`, `useToolCalls`,
`injectToolCalls`): `AssembledToolCall` with plain reactive fields —
`output: T | null`, `status`, and `error` — updated in place as events
arrive so React/Vue/Svelte/Angular can render from snapshots without
`await`, effects, or Suspense around promises.
- Add generic `AssembledToolCall<TName, TInput, TOutput>` plus
`id`/`args` aliases; point `InferToolCalls` at assembled streaming
handles and add `AssembledToolCallFromTool` (exported as
`ToolCallFromTool` from `@langchain/react`, `@langchain/vue`,
`@langchain/svelte`, and `@langchain/angular`).
- Rework `ToolCallAssembler` around a mutable internal handle and
`toClientAssembledToolCall()` for client projections; framework stores
the reactive handle directly.
- Remove redundant `InferAssembledToolCalls` and deprecated `StateOf`;
wire typed `toolCalls` / selector generics across all four framework
packages.
- Expand and align `createAgent`, `createDeepAgent`, and `langgraph`
type tests across React, Vue, Svelte, and Angular; update examples,
protocol-v2 integration tests, and Vue migration docs.

Thanks [@hntrl](https://github.com/hntrl)! - fix(checkpoint-mongodb):
validate configurable checkpoint identifiers before queries

Add runtime validation for `thread_id`, `checkpoint_ns`, and
`checkpoint_id` in
`MongoDBSaver` methods that read and write checkpoints. This prevents
object-based
operator payloads from being passed into MongoDB query filters and
ensures invalid
    configurable values fail fast with explicit errors.

Thanks [@hntrl](https://github.com/hntrl)! - fix(langgraph): prefer
configurable assistant and graph IDs for runtime server info

Update runtime `serverInfo` construction to read `assistant_id` and
`graph_id` from
`config.configurable` first, with fallback to `config.metadata` for
compatibility.
Also expands `execution_info` tests to cover configurable sourcing,
precedence,
    and metadata fallback behavior.

Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - Coalesce
`RootMessageProjection` store writes through a single `setTimeout(0)`
flush so long `messages`-channel replays (on refresh, mid-run join, or
rapid subagent streaming) no longer drain as a per-event microtask chain
that trips React's `Maximum update depth exceeded` guard. Replaces the
previous `MessageChannel`-based batching, which deferred initial-submit
events past the first render and left the UI looking frozen until
refresh.

Hunter Lovell 01dd0462ed fix(sdk): retry connection failures before throwing ConnectionError (#2388) 
## Summary

This change updates SDK retry behavior so connection-related failures
are retried instead of immediately aborting inside `onFailedAttempt`.
When retries are exhausted, the final surfaced error is still coalesced
to a `ConnectionError` with the existing LangGraph-specific guidance.
A focused unit test was added to lock in this behavior.

## Changes

### @langchain/langgraph-sdk

- Updated `AsyncCaller` connection-error handling to only throw
`ConnectionError` on the final failed attempt (`retriesLeft === 0`),
while allowing retries on earlier attempts.
- Added a regression test covering retry count plus final
`ConnectionError` coalescing for connection-refused/fetch-failed style
errors.
- Added a patch changeset for `@langchain/langgraph-sdk` documenting the
retry/coalescing fix.

github-actions[bot] 22c4541b53 chore: version packages (rc) (#2385) 
This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

`main` is currently in **pre mode** so this branch has prereleases
rather than normal releases. If you want to exit prereleases, run
`changeset pre exit` on `main`.

Thanks [@hntrl](https://github.com/hntrl)! - fix(langgraph): prefer
configurable assistant and graph IDs for runtime server info

Update runtime `serverInfo` construction to read `assistant_id` and
`graph_id` from
`config.configurable` first, with fallback to `config.metadata` for
compatibility.
Also expands `execution_info` tests to cover configurable sourcing,
precedence,
    and metadata fallback behavior.

Thanks [@nick-hollon-lc](https://github.com/nick-hollon-lc)! - Coalesce
`RootMessageProjection` store writes through a single `setTimeout(0)`
flush so long `messages`-channel replays (on refresh, mid-run join, or
rapid subagent streaming) no longer drain as a per-event microtask chain
that trips React's `Maximum update depth exceeded` guard. Replaces the
previous `MessageChannel`-based batching, which deferred initial-submit
events past the first render and left the UI looking frozen until
refresh.

dependabot[bot] aa6deb60c7 chore(deps): bump hono from 4.12.14 to 4.12.18 (#2374) 
Bumps [hono](https://github.com/honojs/hono) from 4.12.14 to 4.12.18.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/honojs/hono/releases">hono's
releases</a>.</em></p>
<blockquote>
<h2>v4.12.18</h2>
<h2>Security fixes</h2>
<p>This release includes fixes for the following security issues:</p>
<h3>Cache Middleware ignores Vary: Authorization / Vary: Cookie leading
to cross-user cache leakage</h3>
<p>Affects: Cache Middleware. Fixes missing cache-skip handling for
<code>Vary: Authorization</code> and <code>Vary: Cookie</code>, where a
response cached for one authenticated user could be served to other
users. GHSA-p77w-8qqv-26rm</p>
<h3>CSS Declaration Injection via Style Object Values in JSX SSR</h3>
<p>Affects: hono/jsx. Fixes a missing CSS-context escape for
<code>style</code> object values and property names, where untrusted
input could inject additional CSS declarations. The impact is limited to
CSS and does not allow JavaScript execution. GHSA-qp7p-654g-cw7p</p>
<h3>Improper validation of NumericDate claims (exp, nbf, iat) in JWT
verify()</h3>
<p>Affects: <code>hono/utils/jwt</code>. Fixes improper validation of
<code>exp</code>, <code>nbf</code>, and <code>iat</code> claims, where
falsy, non-finite, or non-numeric values could silently bypass
time-based checks instead of being rejected per RFC 7519.
GHSA-hm8q-7f3q-5f36</p>
<hr />
<p>Users who use the JWT helper, hono/jsx, or the Cache middleware are
strongly encouraged to upgrade to this version.</p>

<h2>v4.12.16</h2>
<h2>Security fixes</h2>
<p>This release includes fixes for the following security issues:</p>
<h3>Unvalidated JSX Tag Names in hono/jsx May Allow HTML Injection</h3>
<p>Affects: hono/jsx. Fixes missing validation of JSX tag names when
using <code>jsx()</code> or <code>createElement()</code>, which could
allow HTML injection if untrusted input is used as the tag name.
GHSA-69xw-7hcm-h432</p>
<h3>bodyLimit() can be bypassed for chunked / unknown-length
requests</h3>
<p>Affects: Body Limit Middleware. Fixes late enforcement for request
bodies without a reliable Content-Length (e.g. chunked requests), where
oversized requests could reach handlers and return successful responses
before being rejected. GHSA-9vqf-7f2p-gf9v</p>
<h2>v4.12.15</h2>
<h2>What's Changed</h2>
<ul>
<li>fix(jwt): support single-line PEM keys by <a
