# 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.

    # Prove the gates RAN. Several skip themselves when the file they read is
    # absent, which is correct in this checkout (docs/ becomes the wiki) and was
    # silently wrong here for months: the modules skipped, CI went green, and an
    # outside branch added nine routes documented nowhere and passed.

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

  agent:
    # Semantic checks on the endpoint agent's pure logic. Until this existed the

    # the guard that decides which paths it will execute - was reviewed by
    # reading alone.
    #
    # The project targets net8.0 and links the platform-pure sources rather than
    # referencing ShopDbEndpointAgent.Core, which is net8.0-windows and cannot
    # run here. See the csproj header for why, and for what that trades away.
    # Runs in well under a second; it does not meaningfully add to gate time.

  lean-build:
    # ADR-013 Phase 5: prove a per-site build carries only its chosen plugins.
    # The profile is the WJ plugin set, so this job proves the build this branch
    # actually ships, not a two-plugin toy. The omission guarantee is what is
    # under test, so the assertions below name a component from EVERY omitted
    # plugin: a set that grows without its check growing is how a leak ships.
    #
    # Chosen (12): backups computers endpoints guides knowledgebase machines
    #              network notifications printers slides tools warranty
    # Omitted (5): employees geenforce measuringtools printedparts usb
    # 'applications' is manifest-less core and ships in every build (ADR-013).
    # endpoints hard-depends on computers, which is already chosen, so the
    # closure adds nothing - if that changes, resolve_plugin_closure.py pulls
    # the dependency in and the absence assertions below start failing, which is
    # the signal to update this list rather than to loosen the check.

  # 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.
