// Plan 4 Task 2 失败测试（先于实现）：Render Snapshot 物化 + build job（ADR-011、V2 spec §9）。
// 覆盖契约（对照计划 Task 2）：
// 1. build job 状态机：queued→snapshotting→building（Task 5 真实构建）→validating
//    （Task 6 最小门禁）→succeeded +
//    build_input_snapshots 行（content/route/asset 三哈希 = 各自**文件字节**（canonicalJson+
//    尾换行）的 sha256——哈希链与落盘文件互证、site_config_revision_id 指向 config v1、
//    theme_key='pilot-minimal'、node_version 等版本信息列真实读 process.versions）+
//    幂等键复用（同 published 集合 → reused 不重跑；只有 succeeded 可复用——failed/
//    崩溃残留行走 stale 宣判+#a 后缀新行自动恢复）；
// 2. 六文件物化（artifacts/jobs/<jobId>/input/）：site.json（config v1）/content.json
//    （published 修订数组，data 全量 + media 引用面，slug 原样）/taxonomies.json（双源全量，
//    source_id 原样含 auto:）/routes.json（html+asset+redirect 并入，query_key/
//    redirect_status/redirect_location/verification_status/indexable/priority 保留）/
//    assets.json（ready 资产实体路径解析：register 快照 metadata.storageRoot+storage_path）/
//    render-manifest.json（versions 四常量 + counts + sourceHashes 三哈希 + urlRewrite 统计）；
// 3. bodyHtml URL 重写：mini post 101 正文绝对 URL 图片命中 media ready 集合 → 根相对
//    public_path；未命中 URL 保留原样 + rewritten/unresolved 计数入 render-manifest；
// 4. canonical JSON 确定性：同输入两次物化 → 六文件字节一致（键排序、无空白）；
// 5. NOT_PUBLISHED：未 publish 站点 → 明确报错且零 build_jobs 行；
// 6. ADR-010 双修订：发布 A → 再导入改内容 current=B → 新 key 再 build → content.json
//    仍为 A（published 冻结语义，spec §15 阶段 4 验收明文）。
// 运行于 globalSetup 临时库（ADR-015）；storage/artifacts 根 os.tmpdir，finally 清理。
