# CI for shopdb-flask on GitHub Actions.
#
# Mirrors the internal CI pipeline. Jobs on push + pull_request:
#   backend          - pytest (SQLite via TestingConfig, no DB service needed)
#   naming           - the CONTRIBUTING.md naming/style gate
#   gates            - proves those checks actually RAN rather than skipping
#   frontend         - vitest + Vue build
#   lean-build       - ADR-013: a per-site build carries only its plugins
#   migrations-mysql - the REAL multi-site deploy path: fresh flask db upgrade
#                      + every plugin's chain on utf8mb4 MySQL 8, idempotent on
#                      a second run. The pytest suite only exercises SQLite
#                      create_all(), so this is what catches an Alembic
#                      regression on MySQL before it ships.

name: CI

# Action versions are the Node 24 native releases (checkout@v5, setup-node@v5,
# setup-python@v6). The v4/v5 generation targets Node 20, which the runners now
# force onto Node 24 with a deprecation warning on every job - working today,
# a hard failure whenever GitHub drops the shim.
#
# Jobs run on the org's self-hosted "arc-runner-set" (enterprise
# ge-aerospace-runner-group, Linux). GitHub-hosted runners are blocked by the
# org IP allow list (hosted Azure runner IPs are not allow-listed -> checkout
# 403), so ubuntu-latest cannot be used here. arc-runner-set checks out from an
# internal allow-listed IP and, being Linux, still supports service containers.

  pull_request:

# A second push supersedes the first: the older run answers a question nobody is
# asking any more, and it holds a self-hosted runner while doing it.

    # outside branch added nine routes documented nowhere and passed.

    # A gate that stops running is worse than no gate, because nobody looks at

  # NOTE: the MySQL-8 migration/seed job (fresh `flask db upgrade` + every
  # plugin chain + strict-mode seeders on a real MySQL 8) runs on the internal
  # CI server, which supports service containers. The org's arc-runner-set is
  # Kubernetes/ARC without docker-in-docker, so GitHub Actions service
  # containers ("services: mysql") are unavailable here ("Job Container is
  # required"). That coverage stays on the internal CI rather than being
  # duplicated on GitHub.
