# /etc/lakehouse/langfuse.env — Langfuse trace observability.
#
# Mode 0640, root:lakehouse. Loaded by every daemon's systemd unit
# via EnvironmentFile=-/etc/lakehouse/langfuse.env. The `-` prefix
# means "missing file is OK" — Langfuse is optional. If the file is
# missing or any of the three env vars below is empty, every daemon
# runs without Langfuse and with no logged warnings (best-effort).
#
# When all three are set, every authenticated HTTP request to every
# daemon emits one Langfuse trace + span, browseable at LANGFUSE_URL.
# /health is exempt to keep LB probes from polluting traces.
#
# Same env vars + same shape as the file the multi_coord_stress
# driver reads — operators ship one langfuse.env across the whole
# deploy.
