# Shares the same Authentik OAuth2 provider/client_id as home's GitLab
# (infrastructure/authentik/gitlab-blueprint.yaml has both redirect_uris
# registered). Same Vault path (secret/gitlab-oauth) home's copy reads
# from - vps-eso-reader policy widened to allow this one extra path
# (infrastructure/vps-eso/manifests/clustersecretstore.yaml's policy,
# applied live via vault CLI, not git-tracked - matches how every other
# Vault policy/auth-method in this repo is set up).
#
# `provider` key added 2026-08-21: found live that GITLAB_OMNIBUS_CONFIG
# (this app's values.yaml extraEnv) is an omnibus-image-only convention
# the CNG webservice image never processes - see the matching comment
# in apps/gitlab/manifests/external-secret-oidc.yaml (home) for the
# full story. The real mechanism needs this key to hold a whole
# YAML-encoded provider block, not raw client_id/secret strings.
