 - 状态：resolved（staging candidate）
 - 首次发现：2026-08-11
-- 最近更新：2026-08-11
+- 最近更新：2026-08-14
 - 影响面：`POST /api/consult` 的个人/一般咨询、Mastra Agent、浏览器流式活动状态、咨询消息执行回执与计费结算；production 默认路径不变。
 - 用户现象：回答可以生成，但服务端在 Agent stream 前已经完成咨询工作流，Agent 只是复述结果；Web 只能按“有无正文”猜测状态，无法证明 Agent 实际加载 Jyotish Skill 或调用排盘工具。
 - 触发条件：咨询进入旧 runtime；route 直接执行 `runConsultationWorkflow()`，再把大段结果塞入 prompt，且仅返回 `text/plain`。
 - 根因：编排权在 Next.js route，不在 Agent；个人 Agent 未绑定服务器排盘工具，Skill/tool 执行合同和公开事件协议均不存在。若直接透传 `fullStream`，还会泄露 reasoning、工具参数/结果、出生资料或 Skill 内容。
-- 修复：增加 `legacy|canary|enabled` runtime 开关；新路径由带 Jyotish Skill 的 Mastra Agent 调用请求级 `run-jyotish-consultation`，工具参数只允许 question/theme，出生资料始终由服务器上下文绑定，并以请求内 Promise 保证重复调用只计算一次。服务端把 `fullStream` 清洗为 NDJSON，仅公开安全的 run/Skill/tool/activity/answer 事件；Skill 和主工具合同未完成时最多重试一次，仍失败则释放预留点数且不保存成功消息。Web 按 content-type 保留 legacy `text/plain` 回滚路径，新路径只累积 `answer.delta`，收到 `run.completed` 后保存 workflow/execution receipt，并用服务器 activity 驱动状态 UI。浏览器断线后服务端继续完成互斥结算。
-- 验证：聚焦回归覆盖动态 Skill 工具、General Agent 无个人排盘工具、服务器绑定参数、并发幂等、unverified precise timing blocked、私有 chunk 过滤、任意 NDJSON 边界、合同完成前正文阻塞、失败不保存、真实 activity UI、execution receipt 持久化、legacy 流与断线结算合同；最终命令和结果记录在本次 staging 发布回报。
-- 防复发：个人咨询不得在 Agent stream 前直接执行主 workflow；不得把出生资料放入模型工具参数；公开流不得包含 reasoning、provider metadata、工具输入/结果或 Skill 正文；只有 `run.completed` 可进入成功消息持久化，步骤最多 32 个，计算与结算都必须请求内幂等。

+- 验证：聚焦回归覆盖动态 Skill 工具、General Agent 无个人排盘工具、服务器绑定参数、并发幂等、unverified precise timing blocked、私有 chunk 过滤、任意 NDJSON 边界、合同完成前正文阻塞、失败不保存、真实 activity UI、execution receipt 持久化、legacy 流与断线结算合同；`ConsultationPlan v2` 的 TypeScript 定向测试 49/49、Python 合同与 API dry-run 测试 27/27 通过；回归覆盖 plan 与嵌套数组冻结，以及 `reported_time`、`lng`、`utc_offset`、`account_balance`、`entitlements`、`access_scopes` 六类恶意嵌套别名不进入模型 packet，同时保留本命、Shadbala、Ashtakavarga、Dasha、Narayana 与 evidence status。目标 ESLint、Python `py_compile` 与 `git diff --check` 通过；全量 `tsc --noEmit` 仅保留与本任务无关的既有 migration fixture 字段和 staging workflow 正则 target 错误。
+- 防复发：个人咨询不得在 Agent stream 前直接执行主 workflow；不得把出生资料放入模型工具参数；公开流不得包含 reasoning、provider metadata、工具输入/结果或 Skill 正文；只有 `run.completed` 可进入成功消息持久化，步骤最多 32 个，计算与结算都必须请求内幂等。版本化 plan metadata 必须 all-or-none，扣点前校验的 plan 必须作为同一不可变对象进入实际 workflow；`required_layers`/`claim_boundary` 只表示 allowlist 合同，不能冒充 layer 已执行或 evidence gate 已通过。
 - 回滚：仅将 staging 的 `CONSULTATION_AGENTIC_RUNTIME` 设为 `legacy`；无需回滚数据库或修改 production。
 - 相关记录：BUG-161
 - 复发自：历史咨询 runtime
