Multi-step agent runs appear as single traces with nested LLM calls, tool calls, cost and latency. Zero client-side code — the gateway reports server-side; clients may pass `metadata` (trace name, user id, tags) to group calls. +3. **Self-hosted Langfuse v3.** Only if data residency requires it: it needs its own stack (Postgres, ClickHouse, Redis, MinIO) — deliberately **not** bundled in this compose file.
