+# phase6_github_mirrors.sh — Configure push mirrors from Gitea → GitHub
+# Depends on: Phase 4 complete (repos exist on Gitea primary)
+# For each repo:
+#   1. Create push mirror config (Gitea → GitHub)
+#   2. Trigger initial sync
+#   3. Disable GitHub Actions (since Gitea is now the CI source of truth)
+# Push mirrors ensure GitHub stays as an offsite backup. Every push to Gitea
+# is automatically mirrored to GitHub on commit + on a schedule.
+# Idempotent: skips repos that already have push mirrors configured.
