# 企微IT智能服务台 — 构建 + 强校验 4 证据链（v1.1 REQ-通用-005 派工）
# =============================================================================
# 做什么：
#   1) 构建坐席 + H5 前端（输出 dist/）
#   2) 强校验 4 证据链（dist 关键字 + 产物 hash + HTTP 200 + 浏览器实测）
#   3) 仅当 4 证据链全过 → 标记发布门禁 GREEN
#
# 用法：
#   bash scripts/build-and-verify.sh                 # 全量构建 + 校验
#   bash scripts/build-and-verify.sh --h5-only       # 仅 H5
#   bash scripts/build-and-verify.sh --skip-e2e      # 跳过 puppeteer 浏览器实测
#
# 退出码：
#   0 = 4 证据链全过
#   1 = 构建失败
#   2 = 强校验证据链失败
#   3 = 浏览器实测失败
# =============================================================================
