# E2E override — layered on top of docker-compose.yml, ONLY for the daily/manual
# Playwright suite. Production config is untouched: this file adds the secret-free
# mock inference service and repoints LibreChat at an E2E-only config so a chat
# exercises the REAL MCP server, ClickHouse, and Langfuse without any API key.
#
#   docker compose -f docker-compose.yml -f docker-compose.e2e.yml up -d --wait
#
# Why a config override instead of editing librechat.yaml: the mock endpoint must
# never leak into a real deployment. CONFIG_PATH points LibreChat at a NEW mount
# path (/app/librechat.e2e.yaml) so it can't collide with the prod bind mount.
