#!/usr/bin/env bash
# 质量审计脚本 —— 跑 4 类检查防漂移
#
# 1. 静态校验：JSON parse / SKILL.md frontmatter / symlink / hook 可执行性
# 2. Installer 功能：18 款工具装 / 卸载 / 幂等
# 3. 上游对齐：hooks 3 文件 + brainstorm scripts 3 文件 + 14 翻译 skill 结构层级
# 4. 交叉引用：README → docs/ 链接 + skill 间引用 + bootstrap 注入路径
#
# 用法：
#   bash scripts/audit.sh                 # 跑全部，FAIL > 0 时 exit 1
#   bash scripts/audit.sh --quick         # 跳过 installer 功能测试
#   bash scripts/audit.sh --no-upstream   # 跳过上游对齐（CI 没 upstream remote 时）
#
# CI 默认在 PR + push to main 跑，发现漂移立刻拦下。
