docker-compose.yml

# Local Postgres for dev parity with Neon (Phase 11 production target).
#
# Usage:
#   docker compose up -d
#   export VEGA_DATABASE_URL=postgresql+psycopg://vega:vega@localhost:5432/vega
#   uv --project backend run alembic upgrade head
#   uv --project backend run vega-serve
#
# The default password here is intentionally weak: this stack listens on
# 127.0.0.1 only and is for local dev. Production uses the managed Neon
# DSN injected via Render env vars (see docs/security/secrets.md).
