  • Add tracer-scoped inheritable metadata/tag options in callback manager while keeping backward-compatible aliases.
  • Move configurable-to-tracing metadata derivation into a tracer-only path and keep ensureConfig metadata mirroring limited to model.
  • Update LangChainTracer default metadata/tag handling and add regression tests for stream events metadata behavior.
