Commit 1cd9578b8 moved the OIDC plugin version out of a hardcoded string
into meta/addons/auth_oidc.yml so the update pipeline tracks it. That
declaration is service-coupled (enabled reads services.sso.enabled), which
obliges the role to ship an integration hook and a per-addon Playwright
spec. Both were missing, so test_addons_integration_tasks and
test_addons_playwright_spec went red.
The hook has no work to do: files/build/install/auth-oidc.sh bakes the
plugin into the image and tasks/04_oidc.yml configures it, included by
tasks/01_manager_ops.yml on the same services.sso.enabled flag. It records
where the wiring actually lives so the coupling stays greppable.
The spec does not follow the pretix shape of hunting a login-page link,
because tasks/04_oidc.yml sets alternateloginurl and /login/index.php
bounces straight to the plugin. It asserts the bounce instead: the login
page must land on the Keycloak openid-connect authorization endpoint
carrying a client_id and a redirect_uri pointing back at auth/oidc.
Rendering the addon flags into playwright.env.j2 is what makes that spec
real. Without lookup('addon_env_flags'), AUTH_OIDC_ADDON_ENABLED is
undefined, skipUnlessAddonEnabled skips forever and the spec is a check
that can never fail.
