+Deploy workflow policy:
+`main` and `master` are both deploy-triggering branches, so `.gitea/workflow-sources/deploy-to-phoenix.yml` and `.gitea/workflow-sources/validate-on-pr.yml` must stay identical across both branches.
+Use `bash scripts/verify/sync-gitea-workflows.sh` after editing workflow-source files, and `bash scripts/verify/run-all-validation.sh --skip-genesis` to catch workflow drift before push.
