# Langfuse v3 — LLM trace / observability (prompts, completions, reasoning, tok/s).
# Fronts the LiteLLM gateway via its native `langfuse` success_callback.
#
# Adapted from the official self-host compose
# (https://raw.githubusercontent.com/langfuse/langfuse/main/docker-compose.yml).
# CHANGES from upstream:
#   - langfuse-web joined to `traefik-net` (tnet) so the LiteLLM container can
#     reach it by name (LANGFUSE_HOST=http://langfuse-web:3000) + homepage labels.
#   - everything else verbatim; internal services stay on the default network and
#     bind to 127.0.0.1 (only langfuse-web:3000 + minio:9090 are host-reachable).
# All secrets live in `.env` on the server (NOT in .env.example). Generate with
# `openssl rand -hex 32` (ENCRYPTION_KEY) / `openssl rand -base64 32` (others).
