name: nightly

# Builds and deploys the staging environment from main every night.
# Runs on the self-hosted runner using Docker-out-of-Docker (the docker
# socket is mounted in), so `docker compose build` produces images on
# the host daemon and `docker compose up` consumes them directly — no
# registry hop.
#
# Operational assumptions (see docs/DEPLOYMENT.md §3 for the full setup):
#
#   1. Single-tenant self-hosted runner. The "Write staging env file" step
#      writes every secret to .env.staging on the runner filesystem; the
#      `if: always()` cleanup step removes it. A multi-tenant runner
#      would need to switch to docker compose --env-file <(stdin) instead.
#
#   2. Host docker layer cache is authoritative. There is no
#      actions/cache; we rely on the host daemon to keep Maven and npm
#      layers warm between runs. A `docker system prune` on the host
#      will cause the next nightly build to be cold (5–10 min slower).
#
# Staging environment isolation:
#   - project name: archiv-staging
#   - host ports:   backend 8081, frontend 3001
#   - profile:      staging (starts mailpit instead of a real SMTP relay)
#
# Required Gitea secrets:
#   STAGING_POSTGRES_PASSWORD
#   STAGING_MINIO_PASSWORD
#   STAGING_MINIO_APP_PASSWORD
#   STAGING_OCR_TRAINING_TOKEN
#   STAGING_APP_ADMIN_USERNAME
#   STAGING_APP_ADMIN_PASSWORD

    # `self-hosted` would never match — no runner advertises it — so the
    # job parks in the queue forever. ADR-011's "single-tenant" promise
    # is at the repo level; sharing this runner between CI and deploys
    # for the same repo is within that boundary.
