- #10694
d3e0809 Thanks @hntrl! - refactor(core): decouple tracer-only metadata defaults from runnable metadata
- 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.
