+## BUG-976 | 普通对话寒暄被当作咨询：全量排盘、长判词与扣点
+
+- 状态：blocked（独立审查、Linux 全量 3566/3566、标准 DB 40/40 及构建/gzip 通过；staging 部署与真人实测待闭环）
+- 首次发现 / 最近更新：2026-09-20。
+- 影响面：普通 `POST /api/consult` 三种模式、流式 UI、咨询账务与历史恢复。
+- 现象与触发：纯打招呼也进入强制计算与报告形状，并扣一次咨询点数。
+- 根因：入口没有非咨询轮，预留与完整咨询链覆盖全部普通消息；原取消函数只退款不持久化回复，没有免费完成语义。
+- 修复：所选模型一次短结构化分类并写寒暄回复，3 秒 fail-open，无 Skill/工具/出生资料注入；只看本轮问题、称呼与最后完整可见问答。普通入口命中后先原子免费结算，再发 answer.delta + 无 receipt 的完成事件。新 service_role-only RPC 沿用 advisory lock，校验所属/状态/回复，记录真实 usage、按 credit_amount 退款，完成请求并释放 reservation。完成重试不退款，已收费咨询不能借此退款。UI 标记持久化，寒暄不造步骤/思考/技法。
+- 验证：假模型、schema、超时、断连、流协议和 SSR 展示定向通过；真实 PostgreSQL 17 覆盖退款幂等、回复冲突、跨用户/会话、取消竞态、已收费拒退、真实成本、事务回滚和无点数来源。Linux tsc 0、lint 0 error/120 既有 warnings；标准 DB 基线 39/39、候选 40/40，完整构建两侧首页 Static，首屏 JS gzip 621,299 → 621,605 B（+0.0493%）。Windows 迁移镜像与 Skill alias EPERM 的历史不删除，Linux 完整全量及部署证据见进度。
+- 防复发：保留分类失败回咨询、服务端专有授权、先持久化后完成、刷新标记、取消/完成共享锁回归；不得加入寒暄关键词/正则/字数分类。独立审查补获 SDK strict 校验日志可能携带原文、且非法输出丢 usage 两项，已局部静默 SDK logger 并保留生成结果后严格解析，真实 SDK 假模型回归断言隐私、fail-open 与成本保留；相关定向主会话复跑 59/59，真实库定向复跑 1/1。
+- 关联记录：BUG-922 / BUG-923 / BUG-937 / BUG-938；这是非咨询轮的新边界，不是旧每轮排盘防线复发。every turn、prepareStep、contractReady 与两处 requireTool:true 未改。BUG-280/305 的空回答或失败不得结算语义保持；BUG-347 的真实咨询思考历史不删除。
+- 边界：reserve 仍在分类前，零点无订阅仍被拦；超时未知 usage 不伪称零，晚 usage 只观测不追写完成账本。
+- 修复版本：实际基线 fcad06372 上的未提交候选，无推送/部署；详见 PROGRESS-consult-smalltalk-fastpath-20260920。

+- 状态：blocked（本地合同通过；真实三模式模型验收待执行）
+- 首次发现 / 最近更新：2026-09-20。
+- 影响面：productConversationVoice、natalSpokenReportContract，窗口/无出生分钟的简短社交回复。
+- 现象与触发：只打招呼也套开场形状；窗口与一般模式拿不到原本命 chit-chat 豁免句。
+- 根因：豁免写在仅本命拼接的常量内，共享 voice 的四步形状没有例外。
+- 修复：将豁免移到三模式共享 voice，明确只回一句、≤20 字、无句号、无星盘主张；本命领域问题仍需原 opener-plus-skeleton。主修仍是 BUG-976 分流，提示词不代替计费与计算边界。
+- 验证：三种指令模板展开共享 voice 后均含豁免，原 OPENER SHAPE 合同保留；未用真实模型假装语义验收。
+- 防复发：共享语气规则不能只放单一模式专属合同；混合咨询/解释/纠错/抱怨仍走完整路径。
+- 关联记录：BUG-922 / BUG-923 的边界之外，不撤销每轮咨询排盘；与 BUG-976 配套。

+- 同日 Linux 补验解除 DB/build/gzip 缺口：根目录 `git archive` + 本轮文件 overlay，解包到独立 named volume，8 个 symlink 保真；容器内按锁文件 `npm ci`。Node 22 Bookworm runner 与独立 Docker 29 DinD 共享网络命名空间、同路径 `/work` volume，内层 daemon 只监听 loopback，无宿主 socket/发布端口；标准 DB 39/39 → 40/40，完整 build 两侧 Static，首页 JS gzip +0.0493%。Windows 原失败仍保留，不修改业务代码掩盖。

+- 历史可见正文可能含此前解读，任务允许这一对历史；只作为用户语义数据，不是工具/系统星盘证据，提示词禁止复述盘上主张。未声称能力剥夺可数学保证模型零幻觉。
+- 订阅无 credit debit 时不加点；reservation released 不再计入 reserved/completed quota，ledger 仍有实际成本。定向覆盖无点数来源分支；真实订阅授权链见真人清单。
+- 供应商忽略 abort 时最多等待约 3 秒；晚 usage 用 late_usage 观测，不追写已完成/释放 reservation，避免改变状态和重复账务。供应商错误/超时未返回 usage 为 unknown，不伪报真实零成本；价格字段计算是既有模型价格估算，不是供应商账单对账。
+- 误判成本按任务书：咨询误判成寒暄会收到一句短回应，需要再问一次；产品接受它比整轮合同失败轻。漏判仍按原咨询处理，宁可多算一次，不用关键词/正则/长度补分类。假模型测试只证明传输/路由/严格解析，不证明真实语义准确率或延迟 P50。

+
+## 主会话独立审查与最终证据
+
+- SQL、RPC 角色、迁移打包/加载静态复核未发现确认缺陷；真实数据库独立回归通过，不等于标准整套 DB 通过。
+- 修复审查发现：Mastra 默认 strict 校验会把非法模型输出附入 SDK 日志，同时在读取 usage 前抛错。现对独立分类 Agent 与结构化输出处理器使用 `noopLogger`，结构化生成采用保留结果的 `errorStrategy: warn`；外层原有 strict schema 仍是唯一接纳门。真实 SDK 内存假模型覆盖合法输出、非法 schema、坏 JSON、供应商异常；验证一次调用、无工具、96 token cap、原文不进 console/stdout/stderr、非法输出仍保留 23/7 tokens。
+- 最终证据：`review-final-targeted.log`（59/59）、`review-final-full-concurrency2.log`（3522/3444/78）、`review-final-failure-comparison.json`（全量与 DB 逐项名单）、`review-final-tsc.log`（0）、`review-final-lint.log`（0 error/120 warnings）、`review-final-db-targeted.log`（1/1）、`review-final-build.log`（EPERM）。
+- 原默认并发多次出现内存分配失败，导致部分测试未完整收集；这些失败日志保留，不用作最终测试总数。中途构建还出现 `.next` rmdir UNKNOWN；最终单独复跑重新到达编译成功后 Skill symlink EPERM。未改业务、断言或依赖去迎合环境。
+- 执行与审查子代理最后因服务端 API 403 insufficient balance 中断；主会话接手完成上述复验与记录，未将中断代理的待完成工作冒充结果。
+- 本轮执行期间远端引用前进至 `5049e784`，相对基线仅新增另一份任务书及索引。未在脏工作树拉取；未来提交/推送前必须重新 fetch、核对 BUG 编号和整合任务索引，不能直接覆盖他人文档。

+## Linux 隔离补验（用户授权继续，2026-09-20）

+- 主机 Docker Desktop：4 CPU / 8 GB；使用本轮专属 runner、DinD 和 named volume，不挂宿主 Docker socket，不访问其他会话容器或凭据。Node `22-bookworm`（拉取 digest `sha256:dd5847a04b0deee391fa145f1f4c6d214196668b6bcc7988ebed67249f226844`），容器内按未修改的 package-lock 执行 `npm ci`；两侧依赖副本相同，不复用 Windows node_modules。
+- 基线从根目录 `git archive fcad06372`；候选为相同 archive + 33 个本轮变更文件。8 个 Git symlink 均保真，overlay 全部逐字节匹配工作树，输入哈希清单 `artifacts/smalltalk/linux-input-manifest.json`。为 Git 文件跟踪合同建立仅容器内使用的临时 Git 快照，非发布提交。

+- [ ] 普通输入「你好」「在吗」「谢谢」「晚安」「哈哈」「我回来了」，检查一句白话、≤20 字、无句号结尾、无客服套话/星月比喻/星盘主张。
+- [ ] 从点击发送到完成不出现虚构思考、活动或技法面板；刷新和切会话再回来仍只有短回复，不冒出「已完成 N 步」。
+- [ ] 记录发送前后点数：预留原额退回，净余额相同；服务端一条 reserve 对一条 refund，不能重复退款。不同模型价格不应假定为 1 点。
+- [ ] 有效订阅用户：无点数退款凭空加点，免费轮不占已完成咨询 quota；定向自动化只覆盖无点数来源结算分支，真实订阅授权链仍需此项。
+- [ ] 零点且无订阅账号仍被现有前端/服务端预留守卫拦住，这是本轮保留的边界，不宣称所有用户可无限免费聊天。
+- [ ] 同会话继续发「你好，帮我看看事业」「？」「你在说什么鬼」「今年怎么样」，应按咨询处理；确认每轮排盘合同与真实咨询扣点未改变。
+- [ ] 今日星语、主题引导、生时校正三个特殊入口不进分类。旧 birth_time_rectification API 入口仍按现有规则拒绝，不能误认为快速通道放行。
+- [ ] 保存 RPC 失败时不得显示成功回复/完成；恢复后可重试。取消先赢时免费完成不得写入；完成先赢时取消不得再退款。
+- [ ] 网络断连或关闭页面后通过历史恢复服务端已完成短回复，净余额不变。
+
+## 模型与观测
+
+- [ ] 受控调用统计确认寒暄只有一次所选模型调用，无工具/Skill/标题/摘要生成；客户端历史不能替换服务端最后完整一对可见历史。
+- [ ] 记录分类 P50/P95、超时率和真实混合意图误判，不能把假模型单测当语义准确率。P50 >1.5 秒时按任务书评估降为 1.5 秒上限，本轮没有真实延迟数据，不擅降。
+- [ ] 超时/坏 JSON/无效 schema/供应商错误均进入原咨询链。分类 tokens、配置版本与估算成本可观测；超时供应商未返回 usage 时标 unknown，不当真实零成本。
+- [ ] 抽检 usage ledger（免费成功的真实 tokens/cost + metadata）与封闭 observability；不写用户问题、姓名、出生资料、密钥或模型原文到日志。
