fix(langchain): let host errors and ambiguous transport failures propagate from MCP OAuth Only connection failures count as unavailable, since a read timeout may follow a refresh-token rotation the server already committed. `begin` now only replaces SDK errors and accepts a 403 challenge from the probe.

fix(langchain): use request protocol version for inline MCP OAuth refresh Also document that `on_event` exceptions propagate, so hosts can raise their own reauthorization error. Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>

feat(core): accept address inside LangChainTracer (#41006) Mirror of https://github.com/langchain-ai/langchainjs/pull/11822, implementing support of `address` in `LangChainTracer` and additional helpers for new LangSmith IA. Bumps the minimum LangSmith version to 0.14.9. ```python from langsmith import address from langchain_core.tracers.context import tracing_v2_enabled with tracing_v2_enabled( address=address.agent_address("support-agent", "production"), ): agent.invoke({"messages": [("user", "Hello")]}) ``` ## Release note Added optional `address` argument for routing traces to a specific agent.

test(langchain): drop the end-to-end PII test for streamed tool-call args It checks what core emits, but the `langchain` release runs its tests against the oldest core it allows, which sends no `tool-call-delta`. Core's bridge tests cover the tool getting its full args, and the PII transformer tests cover redacting slices.

refactor(core): fold `_should_emit_delta` into `_to_content_delta` `_to_content_delta` now returns `None` when a block has nothing to send, so the bridge checks each block type once. Its `block-delta` return was unreachable since tool calls moved to `tool-call-delta`, so it goes, along with `_to_block_delta_fields`. No change in behaviour.
