Langfuse sessions + trace-level input/output - #27
Merged
Merged
Conversation
Conversations group as Langfuse sessions: the web app sends its conversation id as session_id, the API propagates it across the turn's observations (propagate_attributes, id clamped to Langfuse's 200-char limit). The enclosing papertrace-turn observation now sets trace-level input (question) and output (grounded answer), so the trace list reads at a glance.
