 The sibling `upload-records/` directory retains an operation identity, newline-delimited events and terminal result. Feed-write intents retain both previous and requested YAML. Failures record their stage, safe error classification and diagnostic; COS failures also identify `GetObject` or `PutObject`, plus a validated HTTP status and request ID when available. Access-denied reports name the permission to inspect. Raw provider responses and credentials are excluded. Audit initialization becomes visible only after its files are complete; abandoned `.initializing-*` directories are not scanned for completed publication. Writes and readback are recorded before proceeding; missing terminal results mean interruption, not success. Actions also keeps its operation record as a diagnostic artifact for 30 days. These local records are not tamper-proof. COS readback verifies storage bytes, not public CDN behavior; public download acceptance is separate.
 
-If the feed completed but tagging failed, the result is `published-tag-pending` and the job fails visibly. On retry, durable feed-completion evidence permits only tag recovery, even if a later release has advanced the channel. It never re-publishes old YAML. An existing conflicting tag requires administrator investigation and is never moved automatically.
+If the feed completed but tagging failed, the result is `published-tag-pending` and the job fails visibly. On retry, durable feed-completion evidence permits only tag recovery, even if a later release has advanced the channel. It never re-publishes old YAML. An existing conflicting tag requires administrator investigation and is never moved automatically. A rejected tag creation retains its HTTP status and validated GitHub request ID; a follow-up lookup does not replace that failure with a missing-tag error. A repository-rule rejection directs the operator to the matching rulesets without logging the raw response.
 
 Normal publication and manual restoration acquire the same local channel lock. A crash can leave a lock directory under the sibling `publish-locks/`; verify no writer is running before manually removing it. A runner label alone does not coordinate writers on other machines. Keep one publishing machine per channel and preserve its records when migrating.

 同级 `upload-records/` 目录保留操作标识、逐行事件和最终结果。频道写入意图同时记录先前和目标 YAML。失败记录阶段、安全错误分类与诊断；COS 失败还标明 `GetObject` 或 `PutObject`，并在可用时记录经过校验的 HTTP 状态码和 request ID。访问拒绝提示会指出需检查的权限。不保存原始服务响应或凭据。审计初始化在文件完整后才可见；遗留的 `.initializing-*` 目录不参与已完成发布的扫描。写入和回读在继续操作前落盘；没有最终结果代表中断，不代表成功。Actions 还将操作记录保存为诊断 artifact，保留 30 天。这些本地记录不防篡改。COS 回读验证存储字节，不代表公开 CDN 行为；公开下载需单独验收。

 正常发布和手动恢复获取同一把本地频道锁。崩溃可能在同级 `publish-locks/` 下留下锁目录；手动删除前确认没有写入任务运行。runner 标签本身不能协调其他机器的写入。每个频道保持单一发布机器，迁移时保留记录。
