# Test Docker Compose - Ephemeral services for integration testing
# Usage: docker compose -f docker-compose.test.yml up -d
# Cleanup: docker compose -f docker-compose.test.yml down -v
#
# Concurrent worktrees (#3066): the BREEZE_TEST_* variables below let
# `pnpm test-stack up` (scripts/dev/test-stack) run a PRIVATE copy of this
# stack per git worktree — its own compose project, ephemeral host ports, and
# per-project container/network names — so two sessions never TRUNCATE each
# other's database. Every variable defaults to the historical fixed value, so
# plain `docker compose -f docker-compose.test.yml up -d` (CI, single-session
# local) behaves exactly as before.
