 11. 官方同步会拒绝危险输出目录、路径逃逸和现有 symlink 路径组件；下载目标、`.part`、manifest、snapshot、PID、status、log 和控制锁文件不会跟随 symlink，daemon 状态类文件默认以 `0600` 权限创建。
 12. `<output>/official-version-state.json` 会明确保存当前已完成版本、正在拉取版本、上一个可用版本和失败版本；同一 app version、bundle version 和 Addressables root 的失败只保留最新一条，同一版本开始重新拉取或后续发布成功时会清理对应失败记录；`bat status` 会显示最后成功时间、下次检查时间、最后错误摘要、当前阶段、当前下载 URL 进度、版本状态摘要、最近历史失败版本和原因、结构化日志路径和轮转日志路径，人类可读输出不会把完整版本状态 JSON 内联打印。
 13. 资源导入链路已支持 CAS + `ResourceRepository` 索引写入，官方同步可用 `--import-repository` / `BAT_IMPORT_REPOSITORY=1` 在已校验 release 发布后触发导入，默认 CAS 路径为 `<output>/.cas`、SQLite 索引为 `<output>/resources.sqlite`，也可通过 `--import-cas-root`、`--import-resource-db`、`BAT_IMPORT_CAS_ROOT`、`BAT_IMPORT_RESOURCE_DB` 覆盖；`resource.index` RPC/CLI 可按类型、hash、路径模式、官方 release ID、平台、destination、bundle path、archive entry、parse status 和 TextUnit format 分页查询现有索引，release、平台、bundle path 和常用数组 metadata 过滤已下推到 SQLite，数据库不存在时返回 `available=false` 且不会创建空库；`bat doctor cas` 可只读检查既有 CAS 根目录、对象目录、元数据库文件和对象统计，不会因诊断创建空库。`Resource` metadata 已通过 `metadata_json` 兼容迁移保存 release、平台、bundle path、parse status、TextAsset 名称和 TextUnit 数量/格式；当前/上一个/结构变化 catalog、失败 staging 复用、403/404、hash mismatch、CRC、metadata 迁移与 UnityFS 边界校验均有离线回归 fixture 或单测覆盖。
-14. 非 dry-run 官方同步在校验完成并发布后，会先对比上一完整 release 与当前 release 的 `official-download-manifest.json`，在当前 release 下写入 `official-resource-changes.json` 和 `crowdin-translation-handoff.json`；同一 destination 只有 size 或 BLAKE3 改变才算 modified，仅 URL/CDN 根变化但内容相同不会触发解析/翻译候选。随后刷新 `official-parse-cache.json` 和 `official-textunit-index.json`，并从 Added/Modified 资源、parse cache 与 TextUnit 明细索引派生 `official-textunit-tasks.json` 和 `crowdin-textunit-queue.json`；删除资源只进入差异记录，不进入 TextUnit/Crowdin 队列。`parse.text_units` 和 `parse.errors` RPC/CLI 可按 destination、archive entry、path id、class id、field path 和 format 查询当前 release 的 TextUnit 明细与解析错误；`translation.tasks` RPC/CLI 可按 release、destination、archive entry、任务状态、parse status、TextUnit format 和 reason presence 查询离线 TextUnit 翻译任务状态与跳过/失败原因；`translation.task.update` 可回写 provider worker 状态，`translation.worker.run` 可触发 Rust provider worker 独立 claim/lease/retry 并落库 TextUnit 级译文结果，`translation.proofread` 可把汉化 workflow 标记为人工校对中；TextUnit 已包含 class id、field path、字段 offset/byte size 等可追溯定位。Crowdin provider 通过 `CROWDIN_*` 环境变量接入，mock provider 支持本地 fixture；up-to-date 轮询在已有有效解析缓存、TextUnit 明细索引和 TextUnit 队列时只读取摘要，不重复解析。官方同步报告默认 `localized_release_status=not_localized`，含义是原版资源已经发布、汉化资源未发布；受支持的 UnityFS TextAsset、TypeTree string field 和 managed-reference string field 发布成功后会写带 trace 的 `localized-patch-manifest.json`，校验 hash/size/diff/rollback 后才允许 `localized.status` 返回 `status=published`、`status_code=localized.published` 和 `localized_release_status=localized`，并可用 `localized.rollback` 显式恢复上一 release。`bat` 首次启动会在二进制所在目录释放 `config.toml.example` 配置模板（`0600`），`config.toml` 存在且 Unix 权限为 `0600` 或更严格时读取并使用它；`config.toml` 不存在时仅保留模板，不自动读取 example，运行时继续使用环境变量和内置默认值。优先级为命令行参数 > 进程环境变量 > `config.toml` > 内置默认值，`BAT_SKIP_ENV_FILE` 已废弃且不再影响启动；Redis 键为预留。daemon 任务历史持久化在 `<state-dir>/bat-tasks.json`（版本化、`0600` 原子写），重启后任务经 `task.*` 仍可查，中断任务标记 `task_interrupted`（`BAT-ERR-700005`）。官方同步报告还分别统计当前 manifest 复用、历史 release 复用、CAS 复用、网络传输字节和复用回退诊断，下载事件状态使用 `release_reused`、`cas_reused`、`downloaded` 等稳定值。

 15. Rust `bat` 已提供 `res` / `parse` / `i18n` 工作流入口：支持资源拉取、解析刷新、可再生解析缓存清理、离线翻译工作台、人工文本查看/修改/清空、工作台发布前校验、generic manifest 驱动的 Binary/JSON/Text/受支持 UnityFS 汉化发布、人工校对状态标记、既有 patch 能力的批量重打包、单次/限定次数/周期执行和版本化 schedule CRUD。`translation.worker.run` 已接入 provider worker：默认并发 8、范围 `1..=256`，每个 worker 独立 claim 下一项任务并落库 lease、失败分类、重试计划和 TextUnit 译文结果。schedule 查询现在按一级工作流过滤，删除/执行会校验作用域，单轮执行可限制计划数；schedule CRUD、翻译任务查询/交接视图、翻译任务状态回写、provider worker 触发和 `translation.proofread` 状态标记已通过 `bat.sock` 的 RPC 以及 `bat-api` 的鉴权管理接口暴露，dashboard 不维护第二套状态。`bat-api` 已提供内嵌 dashboard MVP，静态资产由 Go embed 暴露在 `/admin/dashboard/`，页面直接调用已有鉴权接口控制资源、调度、翻译、任务、日志、parse TextUnit 查询和 localized 发布/回滚。该工作流只编排已有解析和 patch 能力，不扩大解析器覆盖；完整 AssetBundle 重打包和完整 Web 协作后台仍是后续工作。真实官方网络全量拉取 smoke 已固化，真实大文件与运行报告默认在 `/tmp` 隔离目录，不纳入 Git。Go 细节见 `docs/reports/GO_STATUS.md`。
