name: "CI: E2E"

# Single entry point for every suite that drives a real frontend bundle.
# The bundle is built ONCE by `build-bundle` and restored by every consumer,
# so adding a suite no longer adds another `frontend/scripts/build` run.
#
# Suites and what they need from the bundle:
#
# - Integration Tests: Playwright specs, backend faked with frontend mocks.
# - Composable test suite: Plugin runtime, backend faked with Playwright RPC
#   fixtures. See plugins/apps/composable-test-suite/README.md ("Running in CI").
# - Plugin API Test Suite (mocked): Plugin runtime, backend faked with
#   Playwright RPC fixtures and MOCK_BACKEND=1.
#   See plugins/apps/plugin-api-test-suite/README.md.
#
# Hand-off: `build-bundle` restores `actions/cache` keyed by the checked-out
# SHA, builds only on a miss, and saves it; every consumer restores the same
# key after `needs: build-bundle` completes. A re-run of the same SHA reuses
# the cached bundle instead of rebuilding it.
#
# NOTE: the job `name:` values are the GitHub check contexts, so they are kept
# stable on purpose (branch protection may require them by name). Only the
# workflow file/name changed.
