Recommended action: Call the helpers inside the decorated function/context manager; when using threads or executors propagate contextvars (e.g. contextvars.copy_context().run) or pass the span object and call span.update() directly.
Option: Update via the span object or propagate context [evidence: documented_workaround]
Applies when: Threaded/async code
Steps:
1. with langfuse.start_as_current_observation(name="x") as span: span.update(output=...)
2. for executors wrap work with contextvars.copy_context().run
Expected: Attributes are recorded
