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.

Christian Bromann 0bbe66e31d fix(sdk): normalize HITL edit decisions for Python servers (#2469) 
## Summary
- Normalize HITL resume payloads in `StreamController.respond()` and
`respondAll()` so edit decisions include both `editedAction` and
`edited_action`.
- Add `normalizeHitlResponseForServer` in the SDK UI layer and export it
for direct use.
- Cover normalization with unit tests on the payload helper and on
`respond()` wiring.

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

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.

Venkata Krishnan S 4d03dcbc28 fix(langgraph-checkpoint-mongodb): include pendingWrites in list() results (#2260) 
## Summary

Fixes #2205
Fixes #589

`MongoDBSaver.list()` does not query or return `pendingWrites` in the
yielded `CheckpointTuple` objects. This is inconsistent with
`getTuple()` (which correctly queries the writes collection) and with
other checkpointer implementations like Postgres.

## Fix

Added the same `pendingWrites` query from `getTuple()` into `list()`,
ensuring each yielded checkpoint tuple includes its pending writes.

## Test Plan

- Store checkpoints with pending writes via MongoDBSaver
- Call `list()` and verify `pendingWrites` are populated
- Compare with `getTuple()` output to confirm consistency

Youngho Kim 7c3a98b23a fix(core): prevent Zod schema defaults from overwriting checkpoint state in Command.update (#2035) 
Fixes #2031

When using `Command({ update })` with a Zod schema that has `.default()`
on fields, Zod's `parse()` injects default values for missing fields
into the update object. These injected keys then overwrite values
restored from the checkpoint.

**Root cause:** `_validateInput` passes `Command.update` through
`interopParse(schema, input.update)`, which triggers Zod defaults for
any field not present in the update.

**Fix:** After parsing, filter the result to only include keys that were
present in the original update input — matching the behavior of
`StateSchema.validateInput` which already iterates only over
`Object.entries(data)`.

Added regression tests for both Zod v3 and v4.

Kimaswa Emmanuel Yusufu bc3b98e1bd docs: import messagesStateReducer in low_level.md example (#2464) 
The `messagesStateReducer` example on the Low Level concepts page uses
`messagesStateReducer` as its reducer, but the import only brings in
`Annotation` and the `Messages` type. Copy-pasting it as-is fails to
compile with `Cannot find name 'messagesStateReducer'`. This adds it to
the import. The equivalent example just below already imports it the
same way.

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): pass context with stateful RemoteGraph runs

Pop `thread_id` from run `config.configurable` and forward `context` to
the SDK so checkpointed remote runs accept user context without a 400
from ambiguous parameters. Closes

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`.

Jackjin 26c2e325f4 fix(langgraph-checkpoint-mongodb): MongoDB checkpointer metadata filter (#2186) 
## Summary
- The `list()` method's metadata filter queried `metadata.${key}`
against a serialized binary blob, making it silently nonfunctional (dead
code)
- Added a plain JSON `metadata_search` field alongside the serialized
`metadata` in `put()`, and updated `list()` to query against it
- This is consistent with how Postgres (native JSONB `@>`) and SQLite
(`jsonb(CAST(...))`) handle metadata filtering

## Test plan
- [x] Existing unit tests pass (6/6)
- [ ] Integration test with real MongoDB to verify filter works against
`metadata_search`

Fixes #1591

Pragnyan Ramtha 101b70aa8d fix: preserve non-plain Send args (#2409) 
## Summary
- preserve non-plain object instances while deserializing
`Send`/`Command` argument trees
- keep recursive reconstruction for arrays, plain object records,
serialized `Command`, and serialized `Send` payloads
- add a regression test covering `Set`, `Map`, `Date`, and a custom
class instance passed through `Send`

Fixes part of #1142.

## Test plan
- `pnpm install --frozen-lockfile`
- `pnpm --filter @langchain/langgraph exec vitest run
src/tests/constants.test.ts --testNamePattern "preserves non-plain
objects"`
- `pnpm --filter @langchain/langgraph exec vitest run

Christian Bromann 91a5494715 fix(langgraph): pass context with stateful RemoteGraph runs (#2457) 
## Summary
- Fix [#1922](https://github.com/langchain-ai/langgraphjs/issues/1922)
by porting the Python
[langgraph#6497](https://github.com/langchain-ai/langgraph/pull/6497)
behavior: `RemoteGraph` pops `thread_id` from `config.configurable` (it
stays in the URL path) and passes `context` as a top-level field to
`client.runs.stream()`.
- Stateful remote runs can now combine checkpointing (`thread_id`) with
`context` for middleware / `contextSchema` without the server rejecting
ambiguous parameters.

fixes #1922

Asad Ali 6d4bf927e5 fix(langgraph): StreamMessagesHandler throws "Controller is already closed" errors during parallel streaming with abort #1908 (#1988) 
<h2>Fix Race Condition in
<code>IterableReadableWritableStream.push()</code></h2>

Fixes #1908

<h3>Summary</h3>
<p>This PR addresses a critical race condition in
<code>IterableReadableWritableStream.push()</code> that was causing
<code>TypeError [ERR_INVALID_STATE]: Invalid state: Controller is
already closed</code> errors when streaming a graph with multiple
parallel LLM nodes and aborting the stream (or when it completes
naturally).</p>

<h3>Problem</h3>
<p>Users were experiencing numerous <code>ERR_INVALID_STATE</code>
errors in production when:</p>
<ul>
  <li>Streaming graphs with multiple parallel LLM nodes</li>
  <li>Aborting the stream or when it completes naturally</li>
<li>In-flight token callbacks from LLMs are asynchronous and may still
execute after stream closure</li>
<li>Calling <code>enqueue()</code> on a closed controller throws the
error</li>
<li>This race condition causes console flooding in production
environments</li>
</ul>

<h3>Solution</h3>
<p>The fix implements a robust two-layer approach to handle the race
condition:</p>
<ol>
<li><strong>Pre-checking State:</strong> Checking
<code>this._closed</code> and <code>this.controller</code> existence
before attempting <code>enqueue</code></li>
<li><strong>Try-Catch Protection:</strong> Wrapping the
<code>enqueue</code> operation to catch any remaining race
conditions</li>
<li><strong>Specific Error Handling:</strong> Only suppressing the
"Controller is already closed" error while allowing other errors to
propagate</li>
<li><strong>Maintaining Semantics:</strong> Preserving all existing
functionality while preventing the problematic errors</li>
</ol>

<h3>Code Changes</h3>
<p>Modified <code>push()</code> method in
<code>libs/langgraph-core/src/pregel/stream.ts</code>:</p>

<pre><code>push(chunk: StreamChunk) {
  // Prevent pushing to a closed stream to avoid race condition errors
  if (this._closed || !this.controller) {
// Silently drop chunks when stream is closed - this is expected
behavior
    // when async operations try to push after stream termination
    return;
  }

  try {
    // Forward chunk to passthrough function if provided
    this.passthroughFn?.(chunk);

    // Attempt to enqueue the chunk to the underlying stream
    this.controller.enqueue(chunk);
  } catch (error) {
// Handle the specific case where controller was closed between check
and enqueue
    // This race condition can occur with parallel async operations
    if (error instanceof TypeError && 
        error.message.includes('Controller is already closed')) {
// Silently ignore - this is expected during stream closure with
concurrent pushes
      return;
    }
// Re-throw any other unexpected errors to maintain proper error
reporting
    throw error;
  }
}
</code></pre>

<h3>Enhanced Test Coverage</h3>
<p>Added comprehensive test scenarios covering:</p>
<ul>
  <li>Basic race condition handling</li>
  <li>Concurrent pushes during closure</li>
  <li>Rapid successive operations</li>
  <li>Passthrough function integration during race conditions</li>
  <li>Multiple close calls</li>
  <li>Parallel node simulation mimicking the original issue</li>
</ul>

<h3>Backwards Compatibility</h3>
<ul>
  <li>✅ No changes to public API</li>
  <li>✅ No changes to stream behavior during normal operation</li>
  <li>✅ Maintains all existing functionality</li>
  <li>✅ Only affects the error case (pushes after stream closure)</li>
</ul>

<h3>Testing</h3>
<p>The fix has been validated across multiple scenarios:</p>
<ul>
  <li>Basic race condition scenarios</li>
  <li>Concurrent operations during stream closure</li>
  <li>Multiple parallel nodes simulating the original issue</li>
  <li>Edge cases with multiple close calls</li>
  <li>Passthrough function integration</li>
</ul>

<h3>Impact</h3>
<ul>
<li>✅ Eliminates console flooding with <code>ERR_INVALID_STATE</code>
errors</li>
<li>✅ Improves stability in production environments with parallel
streaming</li>
<li>✅ Maintains performance and functionality of normal stream
operations</li>
  <li>✅ Safe for use with multiple parallel LLM nodes</li>
</ul>

<p>This fix resolves the race condition issue while maintaining full
backward compatibility and following best practices for error handling
in async environments.</p>

Ibrahim Arshad c5dcbd176d fix(langgraph): handle null thread checkpoint in RemoteGraph.getState (#2331) 
Fixes #2328

## Summary
This PR fixes a crash in `RemoteGraph.getState()` when the backend
returns thread state with `checkpoint: null` (for example, an existing
thread before any checkpoint-producing run).

Previously, `_createStateSnapshot` assumed `state.checkpoint` was always
present and dereferenced `state.checkpoint.thread_id`, causing:

`TypeError: Cannot read properties of null (reading 'thread_id')`

## What changed
- Added null-safe checkpoint handling in `RemoteGraph`:
- Introduced checkpoint-to-config conversion with fallback behavior when
checkpoint is null/missing.
- Falls back to the caller-provided config (e.g. `thread_id`) when
server checkpoint is absent.
- Updated state snapshot creation paths (`getState`, `getStateHistory`,
and nested task state snapshots) to use the null-safe conversion.
- Added a regression test:
- `getState handles null checkpoint` in
`libs/langgraph-core/src/tests/remote.test.ts`

## Result
`RemoteGraph.getState()` no longer throws for valid thread states where
`checkpoint` is null, and returns a usable `StateSnapshot` with fallback
config instead.

## Validation
- Added and passed targeted regression test in `remote.test.ts`.
- Ran local preflight checks:
  - formatting, lint, build passed.
- broad unit sweep passed except container-runtime-dependent suites in
`checkpoint-validation` (environment/Testcontainers limitation).

JHSeo 863b555346 fix(sdk): prefer completed task's direct mapping over pending checkpoint's positional guess in fetchSubagentHistory (#2455) 
Fixes #2454

## Problem

`StreamManager.fetchSubagentHistory` (`libs/sdk/src/ui/manager.ts`)
restores each subagent's conversation from its subgraph checkpoint by
first resolving every subagent `tool_call_id` to its subgraph
`checkpoint_ns`. It scans the parent thread's history **newest-first**
and, per checkpoint, tries two strategies:

1. **Direct mapping** — read the `tool_call_id` straight off a completed
PUSH task's result `ToolMessage` (`task.name + ":" + task.id`). The code
comments correctly call this *"more robust than positional alignment ...
preferred"*.
2. **Positional fallback** — when task results aren't populated yet,
align push tasks to the AI message's subagent tool calls by Send index
(`task.path[1]`).

The loop **breaks on the first checkpoint that yields any mapping**
(direct *or* positional). That break is the bug.

When the most recent checkpoint is a still-pending PUSH task — e.g. a
run stopped at an interrupt — its task has no result, so the direct map
is empty and the **positional fallback runs against the head checkpoint
instead**. The fallback's backward scan of `values.messages` then
latches onto a *stale* AI message whose subagent actually **completed in
an older checkpoint**, positionally aligns it to the head's unrelated
pending task, and breaks — before the loop ever reaches the older
checkpoint whose task result holds the **correct** direct mapping.

Net effect: the subagent's history is reconstructed from the **wrong
subgraph namespace** (or not at all). A newer, lower-confidence
positional guess silently shadows an older, authoritative direct mapping
— the opposite of the code's stated intent.

## Fix

Split namespace resolution into two phases:

1. **Phase 1 — direct mapping across the _entire_ history first.**
Collect all `tool_call_id → namespace` mappings from completed task
results before attempting any fallback. These are unambiguous, so no
pending head checkpoint can pre-empt them.
2. **Phase 2 — positional fallback only for tool calls still unmapped**
after phase 1 (the genuinely live/pending case). This preserves the
existing behavior for in-flight runs while guaranteeing a correct direct
mapping is never overwritten by a positional guess.

No backend/protocol change is required — the server already serializes
the correct material (the completed task result with the matching
`tool_call_id`); only the client-side resolution order was wrong.

## Testing

- Added a regression test (`fetchSubagentHistory namespace resolution`):
a pending head checkpoint sitting in front of an older checkpoint that
holds the correct completed mapping. Verified it **fails on the pre-fix
code** (`expected [ 'Stale pending result' ] to include 'Correct
research result'`) and **passes with this change**.
- `vitest run` (SDK): **595 passed**, no type errors.
- `oxlint`: 0 warnings / 0 errors · `oxfmt --check`: clean · `tsc -p
libs/sdk/tsconfig.json --noEmit`: clean.

pawel-twardziak 9eb478ffee fix(langgraph): decouple ContextType from configurable in PregelOptions (#2037) 
## Summary

When a `StateGraph` is created with a `contextSchema` (Zod), two
TypeScript errors occur:

1. **TS2589** ("excessively deep type instantiation") on the
`StateGraph` constructor
2. **TS2322** on `invoke()`/`stream()` - context schema fields (e.g.
`userName`, `userId`) are incorrectly required inside `configurable`
instead of top-level `context`

**Root cause:** `PregelOptions` extends `RunnableConfig<ContextType>`,
which maps the context type onto `configurable?` at the invoke/stream
level. The deep generic chain `StateGraph → Pregel → PregelOptions →
RunnableConfig<ContextType>` causes TS2589 with complex context schemas.
And TS2322 forces users to put context fields in `configurable` instead
of top-level `context`.

**Fix:** Remove the `<ContextType>` generic parameter from
`RunnableConfig` in `PregelOptions` only. This breaks the deep generic
chain at the invoke/stream boundary while preserving typed
`configurable` and `context` inside node callbacks (via
`LangGraphRunnableConfig<T>` / `Runtime<T>`).

## Changes

- **`libs/langgraph-core/src/pregel/types.ts`** - `PregelOptions` now
extends `RunnableConfig` (default) instead of
`RunnableConfig<ContextType>`. This is the only production code change.
- **`libs/langgraph-core/src/pregel/runnable_types.ts`** - Restored
`Runtime.configurable` to `ContextType` and `LangGraphRunnableConfig` to
extend `RunnableConfig<ContextType>` (reverting a previous attempt that
broke backward compat).
- **`libs/langgraph-core/src/tests/pregel.test-d.ts`** - Removed two
`@ts-expect-error` directives for invoke-level configurable (now
`Record<string, any>`, validated at runtime by Zod).
- **`libs/langgraph-core/src/tests/issue_10270_repro.test-d.ts`** -
Regression test reproducing both bugs from the issue.

## Trade-off

| Aspect | Before | After |
|--------|--------|-------|
| `graph.invoke({}, { configurable: { bad: 123 } })` | Compile error |
Compiles, validated at runtime |
| `graph.invoke({}, { context: { ... } })` | Compile error (TS2322) |
Compiles correctly ✓ |
| Node callback `config.configurable` / `config.context` | Typed as `T`
| Typed as `T` (unchanged) ✓ |
| `new StateGraph({ state, context: zodSchema })` | TS2589 | Compiles ✓
|

The only loss is compile-time validation of `configurable` content at
invoke level - mitigated by runtime Zod schema validation which the
codebase already performs.

## @langchain/langgraph-checkpoint@1.0.3

### Patch Changes

[`14f2a79`](https://github.com/langchain-ai/langgraphjs/commit/14f2a796912e81d7f52f0a4f16747f6d0a269209)
Thanks [@Nagendhra-web](https://github.com/Nagendhra-web)! -
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.

## @langchain/langgraph-checkpoint-redis@1.0.6

### Patch Changes

[`1e73c6b`](https://github.com/langchain-ai/langgraphjs/commit/1e73c6b4630bbc4aa976eea4bfc33c4f753b7ee9)
Thanks [@Nagendhra-web](https://github.com/Nagendhra-web)! -
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.

## @langchain/langgraph-api@1.2.3

### Patch Changes

- [#2447](https://github.com/langchain-ai/langgraphjs/pull/2447)
[`80c2806`](https://github.com/langchain-ai/langgraphjs/commit/80c2806cb2da93745a640664bd0cf603c2361da9)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
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.

[`80a8c12`](https://github.com/langchain-ai/langgraphjs/commit/80a8c1200a240fd984edc4deb26a7787d08c7532)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
refactor(sdk): drop StreamSubmitOptions.command and simplify forkFrom

    Remove the misleading submit({ command }) surface from protocol-v2
StreamController; HITL resume is respond() only. Accept forkFrom as a
    plain checkpoint id string and align protocol-v2 servers and docs.

- [#2448](https://github.com/langchain-ai/langgraphjs/pull/2448)
[`2c14b12`](https://github.com/langchain-ai/langgraphjs/commit/2c14b12a80c306578563e77595943037c7c4844d)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
protocol-v2: add `respondAll()` and run config/metadata on interrupt
resume

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.

`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.

protocol-v2: add `respondAll()` and run config/metadata on interrupt
resume

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.

## 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.

Nagendhra Madishetti 14f2a79691 fix(langgraph-checkpoint): block prototype pollution in MemorySaver via reserved storage keys (#2352) 
## Summary

Closes a prototype-pollution sink (CWE-1321) in `MemorySaver`. A caller
able to shape `thread_id`, `checkpoint_ns`, `checkpoint_id`, or
`task_id` (every quickstart, tutorial, and test fixture uses
`MemorySaver` by default) can pass `\"__proto__\"`, `\"constructor\"`,
or `\"prototype\"` and have the subsequent property assignment mutate
`Object.prototype`.

The audit posted in #2346 (cc @etairl) listed *`__proto__` prototype
pollution in `MemorySaver`* among the unfiled findings from the same
security-review pass that produced #2337. This PR confirms the finding
and closes it across all five entry points.

## Vulnerable sinks

`libs/checkpoint/src/memory.ts`:

| Method | Sink |
|---|---|
| `put` | `this.storage[threadId][checkpointNamespace][checkpoint.id] =
...` |
| `putWrites` | `this.writes[outerKey][innerKeyStr] = ...` (with
caller-controlled `taskId` flowing into `innerKeyStr`) |
| `deleteThread` | `delete this.storage[threadId]` |
| `getTuple` |
`this.storage[thread_id]?.[checkpoint_ns]?.[checkpoint_id]` |
| `list` | `this.storage[threadId]?.[checkpointNamespace]` plus
`Object.keys(this.storage[threadId] ?? {})` |

## Proof of concept

\`\`\`ts
import { MemorySaver } from \"@langchain/langgraph-checkpoint\";

const saver = new MemorySaver();

await saver.put(
  { configurable: { thread_id: \"__proto__\", checkpoint_ns: \"\" } },
  /* checkpoint */ { id: \"cp-1\", v: 4, ts: new Date().toISOString(),
channel_values: {}, channel_versions: {}, versions_seen: {} } as any,
  /* metadata  */ { source: \"input\", step: 0, parents: {} } as any,
  {}
);

// Object.prototype is now polluted; every plain object in the process
// inherits the injected key.
const probe: Record<string, unknown> = {};
console.log(\"polluted\" in probe); // true
console.log(probe[\"\"]); // the (formerly per-tenant) saved checkpoint
\`\`\`

Same shape works for `\"constructor\"` and `\"prototype\"`. Non-string
identifiers (`{ \$ne: null }`, arrays, numbers, booleans) reach the same
sinks unchecked.

## Severity

Proposed CVSS 3.1: **High**. `MemorySaver` is the default in every
quickstart and tutorial, and prototype pollution in Node.js is a
documented stepping stone to RCE through gadget chains in downstream
serializers, template engines, and dependency-resolution helpers.
Network-reachable, low-complexity, only the privilege the SDK already
grants to a caller.

## Fix

A single private `assertSafeStorageKey` helper in `memory.ts`, applied
at every public entry that touches `storage` or `writes` (15 call sites
across 5 methods). The guard:

* Asserts the value is a non-empty string (the documented empty
`checkpoint_ns` default is opt-in via `{ allowEmpty: true }`).
* Rejects the three prototype-pollution keys `__proto__`, `constructor`,
`prototype`.
* The `getTuple` and `list` read paths intentionally allow an empty or
undefined `checkpoint_id` so the documented \"fetch latest\" behaviour
continues to work; both paths still reject the magic keys.

\`\`\`ts
const POLLUTION_KEYS = new Set([\"__proto__\", \"constructor\",
\"prototype\"]);

function assertSafeStorageKey(
  field: string,
  value: unknown,
  options: { allowEmpty?: boolean } = {}
): asserts value is string {
/* type check, empty check, pollution check, all with precise
diagnostics */
}
\`\`\`

The guard is a TypeScript `asserts` predicate so call-sites get type
narrowing for free and the compiler enforces that no later code path
uses an unvalidated identifier.

## Why this design

* Mirrors the chokepoint pattern used in PR #2349 (`MongoDBSaver`) and
PR #2350 (`RedisSaver` / `ShallowRedisSaver`). All three savers now
share the same defensive posture at their boundary.
* Single private function: it is impossible for a future call-site to
forget validation, and the `asserts` annotation surfaces missed sites at
compile time.
* No new dependencies, no API changes for valid inputs, no behaviour
change for any documented happy path.

## Test plan

* [x] 22 new tests in
`libs/checkpoint/src/tests/memory-pollution.test.ts` under
`describe(\"MemorySaver prototype-pollution guard\")`, parameterised
across all three pollution keys plus type / empty / accept paths for
every entry point. Includes a cross-test invariant (`afterEach`
snapshots `Object.getOwnPropertyNames(Object.prototype)`) that asserts
pollution did not actually occur even if the guard had been absent.
* [x] Existing checkpoint suite green (\`pnpm --filter
@langchain/langgraph-checkpoint test\`, 93 of 93 including the 22 new
ones).
* [x] Lint clean (\`oxlint\`, 0 warnings, 0 errors on the changed
files).
* [x] Format clean (\`oxfmt --check\`).
* [x] No new dependencies, no public API changes, no behaviour change
for valid string identifiers.

## Disclosure

Original finding credited to @etairl (audit posted in #2346). This PR
was prepared for coordinated public disclosure since the audit list is
already public. Happy to coordinate timing with a private GHSA if the
maintainers prefer.

Pairs with the two earlier sibling fixes from the same audit pass:
* PR #2349 / GHSA-98xf-r82g-9mhx (MongoDB NoSQL injection)
* PR #2350 / GHSA-x3wm-3wx7-g6xm (Redis KEYS / SCAN injection)

Christian Bromann 80c2806cb2 fix(sdk): fold forkFrom client-side and honor multitaskStrategy (#2447) 
## Summary
- Fold the SDK's top-level `forkFrom` into
`config.configurable.checkpoint_id` client-side before sending
`run.start`, so `forkFrom` never reaches the server and the fork target
travels via the single legacy-compliant field used by the existing run
endpoints.
- Drop the server-side `forkFrom` normalization/promotion in both
protocol-v2 reference servers (`ProtocolService.createOrResumeRun` and
the embed protocol routes), reading the fork target solely from
`config.configurable.checkpoint_id`.
- Honor the caller's per-run `multitaskStrategy` (`reject` | `rollback`
| `interrupt` | `enqueue`) instead of hardcoding `interrupt`, falling
back to `enqueue` (the legacy stream-endpoint default, matching the
Python protocol-v2 server) when omitted or unrecognized.

Nagendhra Madishetti 1e73c6b463 fix(langgraph-checkpoint-redis): block KEYS / SCAN pattern injection via top-level identifiers (#2350) 
## Summary

Closes a Redis pattern-injection sink (CWE-77, CWE-943) in `RedisSaver`
and `ShallowRedisSaver`. A caller able to shape `thread_id`,
`checkpoint_ns`, `checkpoint_id`, or `task_id` (multi-tenant SDK
deployments where the `RunnableConfig` originates from request input, or
webhook payloads that flow into a persisted thread) can promote a string
identifier into a Redis glob (`*`, `?`, `[...]`) and read, overwrite, or
wipe checkpoints belonging to other tenants.

The audit posted in #2346 (cc @etairl) listed *Redis key/glob injection
in `RedisSaver` / `ShallowRedisSaver`* among the unfiled findings from
the same security-review pass. This PR confirms the finding and extends
the fix to all key-building sites in both savers.

## Vulnerable sinks

`RedisSaver` (`libs/checkpoint-redis/src/index.ts`):

| Method | Sinks |
|---|---|
| `getTuple` | `keys(\"checkpoint:\${threadId}:\${checkpointNs}:*\")`
plus the direct \`json.get\` key |
| `list` (fallback paths) |
`keys(\"checkpoint:\${threadId}:\${checkpointNs}:*\")`,
`keys(\"checkpoint:*:\${checkpointNs}:*\")` |
| `put` |
`\`checkpoint:\${threadId}:\${checkpointNs}:\${checkpointId}\`` plus the
zset key |
| `putWrites` | per-write key, zset key, checkpoint key |
| `deleteThread` | `keys(\"checkpoint:\${threadId}:*\")`,
`keys(\"writes:\${threadId}:*\")` |
| `loadPendingWrites` |
`keys(\"checkpoint_write:\${threadId}:\${checkpointNs}:\${checkpointId}:*\")`
|

`ShallowRedisSaver` (`libs/checkpoint-redis/src/shallow.ts`) has the
same five public entry points plus the equivalent helper.

## Proof of concept

```ts
import { createClient } from \"redis\";
import { RedisSaver } from \"@langchain/langgraph-checkpoint-redis\";

const client = createClient({ url: process.env.REDIS_URL! });
await client.connect();
const saver = new RedisSaver(client);

// Tenant A and Tenant B persist checkpoints normally.
await saver.put(
  { configurable: { thread_id: \"tenant-a\", checkpoint_ns: \"\" } },
  /* checkpoint */ { id: \"cp-a\", v: 4, ts: new Date().toISOString(),
                     channel_values: {}, channel_versions: {}, versions_seen: {} } as any,
  /* metadata  */ { source: \"input\", step: 0, parents: {} } as any,
  {}
);
await saver.put(
  { configurable: { thread_id: \"tenant-b\", checkpoint_ns: \"\" } },
  { id: \"cp-b\", v: 4, ts: new Date().toISOString(),
    channel_values: {}, channel_versions: {}, versions_seen: {} } as any,
  { source: \"input\", step: 0, parents: {} } as any,
  {}
);

// Attacker controls only the thread_id of their own request.
// Without the guard, deleteThread expands the KEYS pattern to a glob
// and deletes BOTH tenants' checkpoints.
await saver.deleteThread(\"*\");
// Both \`cp-a\` and \`cp-b\` are gone.
```

The same shape (`\"*\"`, `\"tenant-?\"`, `\"tenant-[ab]\"`, `\"a\\b\"`)
is accepted by every Redis pattern site in the table above.

## Severity

Proposed CVSS 3.1: **High**. The most severe sink is `deleteThread`,
which gives full availability impact across every tenant in the
database, with confidentiality (`getTuple`, `list`) and integrity
(`put`, `putWrites`) impacts on the other paths. Network-reachable,
low-complexity, only the privilege the SDK already grants to a caller.

## Fix

A single `assertSafeKeyComponent` helper exported from `./utils.js`,
applied at every key-building site (27 calls across 2 saver files plus
the helper export). The guard:

* Asserts the value is a non-empty string (the documented empty
`checkpoint_ns` default is opt-in via `{ allowEmpty: true }`).
* Rejects the Redis pattern meta-characters `* ? [ ] \`.
* Rejects the `:` delimiter that would otherwise corrupt the
colon-delimited key structure.

\`\`\`ts
export function assertSafeKeyComponent(
  field: string,
  value: unknown,
  options: { allowEmpty?: boolean } = {}
): asserts value is string {
  const { allowEmpty = false } = options;
if (typeof value !== \"string\") { /* precise diagnostic */ throw ... }
  if (!allowEmpty && value === \"\") { throw ... }
  if (REDIS_KEY_FORBIDDEN.test(value)) { throw ... }
}
\`\`\`

The guard is a TypeScript \`asserts\` predicate so call-sites get type
narrowing for free and the compiler enforces that no later code path
uses an unvalidated identifier.

## Why this design

* Mirrors the maintainers' existing primitive-only pattern
(\`escapeRediSearchTagValue\`) in the same file.
* Single chokepoint: it is impossible for a future call-site to forget
validation.
* No new dependencies, no API changes for valid inputs, no behavior
change for any documented happy path.
* Pairs with PR #2349 (NoSQL injection in MongoDBSaver) so both backends
now share the same defensive posture at the saver boundary.

## Test plan

* [x] 11 new tests under \`describe(\"assertSafeKeyComponent\")\` in
\`libs/checkpoint-redis/src/tests/utils.test.ts\` covering accept and
reject paths for every input shape (normal string, empty with and
without \`allowEmpty\`, every Redis meta-character, colon delimiter,
every wrong type).
* [x] Existing \`escapeRediSearchTagValue\` suite still green
(regression).
* [x] Full suite green (\`pnpm --filter
@langchain/langgraph-checkpoint-redis test\`, 21 of 21).
* [x] Format clean on all 4 changed files (\`oxfmt\`).
* [x] No new dependencies, no public API changes, no behavior change for
valid string identifiers.

## Disclosure

Original finding credited to @etairl (audit posted in #2346). This PR
was prepared for coordinated public disclosure since the audit list is
already public. Happy to coordinate timing with a private GHSA if the
maintainers prefer.

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): preserve apiUrl path prefix in stream transport URLs

Use BaseClient-style URL concatenation in `toAbsoluteUrl` so SSE and
WebSocket
subscriptions work when the SDK is pointed at a proxied apiUrl with a
path
    prefix (e.g. `/api/chat-langchain`).

Christian Bromann dbbcb636e7 fix(sdk): preserve apiUrl path prefix in stream transport URLs (#2441) 
## Summary
- Fix `toAbsoluteUrl` to concatenate `apiUrl` and path instead of using
`new URL(path, base)`, which dropped path prefixes on proxied
deployments.
- Route WebSocket stream URL construction through `toAbsoluteUrl` for
consistency with SSE transport.
- Add unit and integration tests for proxied apiUrl paths, plus shared
transport test helpers.

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.

Hunter Lovell 6b188e80ab fix(sdk): avoid eager stream getter evaluation (#2434) 
## Summary

fix(sdk): avoid eager stream getter evaluation during spread

This fixes a React `useStream` development-mode failure where passing
the stream handle through components that clone or rest-spread props
could accidentally read lazy getters. The guarded `history` getter still
throws when explicitly accessed with `fetchStateHistory: false`, but
object spread no longer trips that path or widens `streamMode` by
touching optional accessors.

## Changes

`@langchain/langgraph-sdk`

- Marks optional `useStream` accessors (`history`,
`experimental_branchTree`, `toolProgress`, `subagents`,
`activeSubagents`) as non-enumerable on the returned stream handle.
- Preserves explicit access behavior for those accessors, including the
existing `history` guard and stream mode opt-in for
`toolProgress`/`subagents`.
- Adds React hook regression coverage for object spread, explicit getter
access, and stream mode inference.

Christian Bromann cfc8d274e4 fix(sdk): unwrap Command tool outputs and hide scoped task tools (#2435) 
## Summary

- Filter scoped deep-agent `task` dispatch events out of `sub.toolCalls`
so subagent tool streams only show real worker tools.
- Unwrap LangGraph `Command` payloads in `parseToolOutput` when they
carry an embedded `ToolMessage`, so `tc.output` resolves to the actual
tool result instead of raw graph state.
- Share the scoped-task filter between client subagent handles and
framework tool-call projections.

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 b1d307ab84 ci(infra): run framework browser tests only when paths change (#2425) 
## Summary
- Add a `detect-changes` job to the browser test workflow using
`dorny/paths-filter@v3.0.2`.
- Run all four framework browser jobs when `libs/sdk/**` changes or when
this workflow file changes.
- Run only the matching job when `libs/sdk-react`, `libs/sdk-angular`,
`libs/sdk-vue`, or `libs/sdk-svelte` changes.
- Keep the full matrix on `workflow_dispatch` (manual runs and CI
dispatched via workflow_dispatch).

배성훈 c088c7659c feat(supervisor): widen agents type to accept createAgent graphs (#2317) 
## Summary

- Add a broader `CompiledStateGraph<any, any, string, any, any>` to the
`agents` union in `CreateSupervisorParams`
- Graphs produced by `createAgent` from `langchain` (via `.graph`) are
now accepted alongside existing `createReactAgent` graphs and
`RemoteGraph`
- The original `AnnotationRootT`-parameterized `CompiledStateGraph` type
is preserved for backward compatibility

## Motivation

The new `createAgent` API in the `langchain` package returns a
`ReactAgent` whose `.graph` property is a `CompiledStateGraph` with a
different state schema (`BuiltInState`) than the
`MessagesAnnotation`-based state from `createReactAgent`. Since
`createReactAgent` is deprecated in favor of `createAgent`,
`createSupervisor` needs to accept both graph types.

At runtime this already works — `makeCallAgent` types its `agent`
parameter as `any` and only accesses `.name`, `.invoke()`, and
optionally `.description`. The type constraint on the `agents` parameter
was simply too narrow for the new API.

## Changes

### `@langchain/langgraph-supervisor` (`libs/langgraph-supervisor`)

- Updated `CreateSupervisorParams.agents` type to include
`CompiledStateGraph<any, any, string, any, any>` in the union alongside
the existing strictly-typed `CompiledStateGraph` and `RemoteGraph`

## Test plan

- [x] `pnpm build` passes for `@langchain/langgraph-supervisor`
- [x] Consuming project using `createAgent` + `createSupervisor`
compiles without errors
- [x] Existing supervisor tests still pass

Jackjin ebeb1452d2 fix(langgraph-checkpoint-redis): fix deleteThread using wrong key pattern for writes (#2208) 
## Summary

Fixes #2207

- Fix `deleteThread()` using incorrect `writes:` prefix instead of
`checkpoint_write:` for write key deletion
- Add missing cleanup of `write_keys_zset:` entries, matching the
correct implementation in `ShallowRedisSaver`

The bug was found by comparing `RedisSaver.deleteThread()` with
`ShallowRedisSaver.deleteThread()` in `shallow.ts`, which correctly uses
`checkpoint_write:` prefix and also cleans up zset keys.

## AI Disclosure

This bug was identified through code review with AI assistance. The fix
aligns the standard `RedisSaver` implementation with the existing
correct `ShallowRedisSaver` implementation.

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.

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.


# Releases
## @langchain/langgraph@1.3.2

### Patch Changes

- [#2415](https://github.com/langchain-ai/langgraphjs/pull/2415)
[`9d3c9dd`](https://github.com/langchain-ai/langgraphjs/commit/9d3c9dd3182059f9eca9fd9b14d8f7466b4338c4)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
Move `@langchain/core` from a runtime dependency back to a required peer
dependency so installing the SDK alone no longer pulls in
`@langchain/core` (and `js-tiktoken`, etc.). Consumers that use
streaming or message coercion must install `@langchain/core` explicitly
or via `@langchain/langgraph`.
