 ## [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。
+
+## [0.3.28] - 2026-11-10
+
+### 新增与改进
+
+- 新增英文界面和语言切换，覆盖任务、审批、设置、通知及计划任务等页面，并统一常用状态、日期与错误提示的翻译。
+- 流量页面展示完整流量 ID，支持按 ID 搜索及在 HTTP 环境复制；Agent 可直接使用该 ID 读取已有流量。
+- 漏洞统计与列表使用相同筛选条件，区分独立漏洞和原始上报记录数量。
+
+### 修复
+
+- Basic Auth 会话失效时在当前标签页恢复认证，避免后台请求反复弹出浏览器认证框，并保留应用登录状态。
+- 修复英文界面预览、覆盖度图谱生命周期及部分页面运行时错误，并为认证、出站探测等错误补充可翻译的错误码。

 Docker 和内嵌前端二进制直接支持此功能。`next dev` 的认证检查仅向本机回环后端转发凭据（`localhost`、`127.0.0.1` 或 `::1`）；前端与后端应使用同一主机名。远程开发后端未开启验证时仍可使用；开启后请通过内嵌前端访问远程服务，避免跨域验证 Cookie 问题。

+# Jev / System One 接入核验
+
+核验日期：2026-11-03。协议依据：TypeSafe 官方 `https://api.typesafe.ai/openapi.json`（OpenAPI 3.1.0，API schema 0.2.0）。
+
+## 请求与配置
+
+- 使用 Bearer API Key，通过 `POST /v1/systemone` 提交 `model`、`state` 和命名的 `questions`。拦截裁决使用 `choice` 问题及 `allow / ask / deny` criteria。
+- `GET /v1/models` 返回 `models[].name`，不是 OpenAI 的 `data[].id`。模型管理页可加载账号可用模型，默认别名为 `jev-latest`。
+- Base URL 可填服务根地址、`/v1` 或完整 `/v1/systemone` 地址；只接受 HTTP(S)，不接受查询参数和片段。
+- 使用配置中的独立代理；空代理直连，不继承进程代理环境。Jev 配置仅可用于拦截裁判，不可设为聊天或任务模型。
+
+## 裁决与失败处理
+
+- 校验 `answers.decision` 的类型、裁决值、必填置信度和三个概率字段。置信度及概率必须是 0–1 的有限数字；无效响应进入现有重试/失败策略，不作为有效放行结果。
+- 低于配置阈值的结果转人工审批；证据不完整或截断时，Jev 的 `allow` 转为 `ask`。
+- HTTP 错误、格式错误及取消/超时作为调用失败；生产调用遵守裁判单次超时和重试配置。连接测试及模型列表查询限时 30 秒。
+- 记账使用官方 `usage.input_tokens / output_tokens`；审查记录保留输入和配置摘要。
+
+## 验证范围
+
+自动测试覆盖模型列表原生协议、代理、URL 规范化、正常裁决、异常响应、低置信度、证据截断、使用量和管理接口接线；前端类型检查、静态导出和现有前端 API 回归测试亦纳入发布验证。
+
+**未使用真实 Jev API Key 调用生产服务。** 虚拟机没有保存 Jev profile，当前启用的裁判为其他模型。协议与模拟服务测试不能证明实际账号权限、余额、服务可达性或模型判定准确率；上线使用前仍应保存 Jev 配置并执行连接测试和业务样本验收。
+
+本次新版本包含 Jev 功能及上述修复。历史 `v0.3.25` 不含 Jev 接入；将虚拟机恢复到该版本不会部署 Jev 功能。

+
+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。
