# Project E — idempotent deploy script.
#
# Intended to run from the Gitea Actions self-hosted runner (projecte-runner),
# which lives on the same host as the docker-compose stack, but it is also safe
# to run manually from a checkout or from DEPLOY_DIR itself.
#
# Safety guarantees:
#   - The host .env is never overwritten (secrets stay on the host).
#   - The project-e-pg-data volume is never touched/deleted.
#   - Safe to re-run: schema sync (drizzle-kit push --force) and trigger
#     application are idempotent, and `docker compose up -d` only recreates
#     services whose config/image changed.
