# 国内域名机一键部署 · GH-CVM-DOMAIN-PROD-01 (广州 2C2G)
# Sovereign: TCS-0002∞ · 国作登字-2026-A-00037559
# 守护: 铸渊 · ICE-GL-ZY001
#
# 这是**唯一**被授权部署到 ZY-SVR-CN01 的工作流, 已登记在
# scripts/preflight/cn-isolation-allowlist.json 的 cn_server_workflows.
#
# 误触锁: confirm_phrase 必须输入「重装广州」, 否则自动降级 dry-run.
# 自动回滚: 远端 bootstrap.sh 失败时自带 trap autorollback,
#           workflow 这一层再捞回 deploy-report.md 贴 GH summary.
#
# 必需 Secrets:
#   ZY_CN_SERVER_HOST / ZY_CN_SERVER_USER / ZY_CN_SERVER_KEY
#   ZY_CN_SERVER_PATH (默认 /data/guanghulab)
#   ZY_CN_SSH_PORT (可选, 默认 22)
