  The final usage chunk in `_streamResponseChunks` was only yielded via the async generator but did not call `runManager.handleLLMNewToken()`. This meant callback-based consumers (e.g. LangGraph's `StreamMessagesHandler`) never received the `usage_metadata` chunk. Added the missing `handleLLMNewToken` call to match the behavior of the main streaming loop.

  Introduces `createNamespace` utility for hierarchical symbol-based branding of class hierarchies.
  All LangChain error classes now use this pattern, replacing hand-rolled duck-type `isInstance` checks
  with reliable cross-realm `Symbol.for`-based identity.
  - New `LangChainError` base class that all LangChain errors extend
  - New `createNamespace` / `Namespace` API in `@langchain/core/utils/namespace`
  - Refactored `ModelAbortError`, `ContextOverflowError` to use namespace branding
  - Added `ContextOverflowError.fromError()` static factory method
  - Deprecated `addLangChainErrorFields` in favor of `LangChainError` subclasses
  - Migrated Google provider errors (`GoogleError`, `ConfigurationError`, etc.) to namespace branding
  - Updated Anthropic and OpenAI providers to use `ContextOverflowError.fromError()`

  When messages originating from Anthropic (e.g. via `ChatAnthropic`) are passed to `ChatOpenAI`, Anthropic-native `tool_use` blocks in `message.content` are now filtered out during conversion. These blocks are already represented in `message.tool_calls` and would cause an OpenAI API error if passed through.

  - Adds `reasoningEffort` to `BaseChatOpenAICallOptions` for easier configuration of reasoning models
  - Automatically coalesces `reasoningEffort` into `reasoning.effort` when calling reasoning models (o1, o3, etc.)
  - If both `reasoningEffort` and `reasoning.effort` are provided, `reasoning.effort` takes precedence
  - Marked as `@deprecated` to encourage use of the full `reasoning.effort` option

  - Added `ModelAbortError` class in `@langchain/core/errors` that contains partial output when a model invocation is aborted mid-stream
  - `invoke()` now throws `ModelAbortError` with accumulated `partialOutput` when aborted during streaming (when using streaming callback handlers)
  - `stream()` throws a regular `AbortError` when aborted (since chunks are already yielded to the caller)
  - All provider implementations now properly check and propagate abort signals in both `_generate()` and `_streamResponseChunks()` methods
  - Added standard tests for abort signal behavior

- [#9900](https://github.com/langchain-ai/langchainjs/pull/9900) [`a9b5059`](https://github.com/langchain-ai/langchainjs/commit/a9b50597186002221aaa4585246e569fa44c27c8) Thanks [@hntrl](https://github.com/hntrl)! - fix(providers): add proper abort signal handling for invoke and stream operations
  - Added early abort check (`signal.throwIfAborted()`) at the start of `_generate` methods to immediately throw when signal is already aborted
  - Added abort signal checks inside streaming loops in `_streamResponseChunks` to return early when signal is aborted
  - Propagated abort signals to underlying SDK calls where applicable (Google GenAI, Google Common/VertexAI, Cohere)
  - Added standard tests for abort signal behavior in `@langchain/standard-tests`

  This enables proper cancellation behavior for both invoke and streaming operations, and allows fallback chains to correctly proceed to the next runnable when the previous one is aborted.
