#!/usr/bin/env bash
# forgejo-oauth-source.sh — keep the Forgejo OAuth login source aligned with
# ZITADEL.
#
# Forgejo stores login sources in its database, not in GitOps, and its REST API
# does not expose them. `tea` has no auth-source command either (tea admin only
# manages users), so the supported writer is the in-pod CLI:
# gitea admin auth update-oauth
#
# The source name is the label on the "Sign in with ..." button AND the callback
# path (/user/oauth2/<name>/callback), so a rename changes the registered
# redirect URI. Register both spellings in ZITADEL (zitadel-provision.py does)
# before renaming.
#
# Usage:
# scripts/iam/forgejo-oauth-source.sh status
# scripts/iam/forgejo-oauth-source.sh rename zitadel
