 ## [Unreleased]
 
-## [0.3.29] - 2026-11-11
-
-### 新增与改进
-
-- 新增可选「无成果止损」：按实际运行时长、独立漏洞数量与最低等级做一次检查，未达标时自动收尾并显示「无成果停止」；暂停、排队及计划窗口外不计时，复活后重新计时，默认关闭。停止状态复用 `timeout`，已有 `on_task_timeout` 触发器仍会执行并可能消耗 token。
-- 任务详情新增只读文件浏览，支持目录导航、最近文件、文本与图片预览、单文件下载及目录 ZIP 下载；展示意图目录对应的标题和状态，并提供中英文界面。
-
-### 修复
-
-- 无成果检查与漏洞写入串行化，并在同一事务内重新计算独立漏洞数量，避免临界时刻已达到成果要求的任务被误停止。
-- 旁路问答摘要为空、被截断或过长时自动重试一次，并细分失败原因；失败摘要不写入缓存，重试计入原有调用次数、用量及超时限制。

-
-原来的“旁路摘要未完整生成，请重试”合并了空正文、`max_tokens` / `length` 截断和工具调用三个不同原因，任一摘要分块失败都会阻止正式回答。首次提问遇到过长主快照也会触发摘要，不仅是旁路历史超过 20 组时。固定 2048 tokens 且没有摘要恢复，使用户手动重试仍可能重走相同失败路径。
-
-`Thinking=disabled` 是请求意图，不能保证所有兼容端点停止推理。例如当前 norma v0.4.3 的 Chat Completions 适配器仍透传 profile 的 `reasoning_effort`；推理可能消耗输出预算。提高恢复预算用于容纳这种情况，摘要正文仍须符合原有 2200 tokens 估算上限。最终错误现在区分输出截断（含预算及停止原因）、无正文、工具调用和摘要过长。
-
-以上是代码路径和模拟 Provider 回归所确认的失败机制。本地测试库没有旁路请求或对应模型调用记录，不能据此判定用户现场具体属于哪一类，也不能量化发生频率。
-
-本次验证：`go test -race ./sidequestion -count=1` 和后端构建通过；新增用例覆盖空正文、仅思考、两种截断原因、摘要过长的恢复，以及 UTF-8 多分块、32K/200K 窗口、取消、共享调用上限、失败用量和缓存完整性。隔离 PostgreSQL 下运行旁路及归档相关的 db/server/agent 测试，33 个测试及子测试通过、无跳过。`TestSideTaskArchiveVersions`（含三个子测试）和 `TestSideTaskContextModelUnavailableIsDistinct` 失败；通过 Go overlay 使用起始提交 `5860bf8` 的摘要代码与测试重跑，失败项及通过数一致，属于已有基线问题。本次未调用真实模型或部署服务。
