+# Idempotent repair of the ZITADEL identity links that live inside three
+# application databases.
+#
+# Why this exists: Forgejo, Paperless and Immich each store the link between
+# their local account and the identity provider INSIDE their own database, not
+# in Kubernetes. When the IdP changed from Authentik to ZITADEL, every one of
+# those rows kept the Authentik subject and the provider name. The result was:
+#
+#   Forgejo   -> /user/link_account, never a login
+#   Paperless -> /accounts/3rdparty/signup/, never a login
+#   Immich    -> 400 "email already linked to different account"
+#
+# Each row is keyed on a stable, human-meaningful column (the account email or
+# username) rather than a numeric primary key, so a re-run converges and a
+# fresh database does not need the hard-coded ids this was first discovered on.
+#
+# The ZITADEL subject below is the `sub` claim of the operator account. It is
+# NOT a client id: every one of the three databases stores the subject.
+#
+# Re-run policy: safe. Every statement is an UPDATE that matches its row by
+# email/username, and the Job prunes itself so ArgoCD can recreate it on the
+# next sync.
