`false`
- reuse numeric `fetchStateHistory` limits for subagent namespace
discovery
- add orchestrator regression coverage for both cases
## Context

fix(langgraph): propagate tracer metadata defaults from configurable ( #2315 )
...
## Summary
This updates Pregel callback manager initialization to pass
`tracerInheritableMetadata` defaults derived from `config.configurable`,
and narrows `ensureLangGraphConfig` metadata mirroring to the
allowlisted LangGraph identifiers used in stream/runtime metadata.
## Changes
### `@langchain/langgraph` (`libs/langgraph-core`)
- Updated Pregel callback manager setup to configure core callbacks with
`tracerInheritableMetadata` based on configurable primitive values,
excluding internal and secret-like keys.
- Hoisted tracing default logic into `_getTracingMetadataDefaults` and
`_excludeAsMetadata` for parity with the Python implementation shape.
- Restricted `ensureLangGraphConfig` configurable-to-metadata
propagation to the identifier allowlist:
- `thread_id`
- `checkpoint_id`
- `checkpoint_ns`
- `task_id`
- `run_id`
- `assistant_id`
- `graph_id`
- Updated config tests to assert the narrowed metadata propagation
behavior.

458d66bf66
Prevent values from getting overrwritten on interrupt event ( #2302 )
...
Issue:
In multi-agent sustem with handoffs like this example:
https://docs.langchain.com/oss/python/langchain/multi-agent/handoffs#multiple-agent-subgraphs ,
if we trigger an interrupt from an agent within a swarm workflow, the
interrupt is propagated and sent twice, the last interrupt contains
values from the main graphs state, which is always going to be behind
the state of the agent from where interrupt is triggered. So,
temporarily, the message data becomes empty, it gets refilled when
interrupt is resumed
Fixes:
Do not update values when interrupt is recieved, just update the
interrupt in the state with the latest __interrupt data.
