-# PROGRESS · 普通对话接口拆分第一步
-
-issue #66。分支 `codex/consult-route-split-20261013`，从 `origin/staging` `32b238cf` 新建。按任务书 §7 先让出完成回答、直达校正、输出审核和上下文摘要，再让出开流前整段（T1）。T4、T5 保留。
-
-## 做了什么
-
-搬进 `frontend/src/lib/consult/settlement.ts` 的工厂 `createConsultSettlement`：
-
-| 原位置 | 新位置 |
-| --- | --- |
-| 预留回调体 | `reserveCredit` |
-| `cancel` 函数体 | `cancel`（route 留一行转调用） |
-| 追加问题与写满 409 | `appendQuestion` |
-| 寒暄 `complete_consultation_free` | `completeSmalltalk` |
-| `usagePayload` 函数体 | `usagePayload`（route 留一行转调用） |
-| 三个 schema、`first`、`retryDetachedSettlement`、`mergeUsage`、`Usage` | 同文件导出；完成回答仍从 route 引用 |
-
-仍留在 `route.ts`：`completeResponse`、`completeDirectRectificationTurn`、`moderateAnswer`、`completeModeratedResponse`、`checkpointConsultationContext`，以及开流前的旧入口、限额、提示词提取、历史窗口、输入审核。
-
-`route.ts` 行数 1943 → 1780，净减 163。`accounting.rpc(` 仍有 3 处（完成回答、审核后完成、直达校正）。目标净减 450 与 rpc 为 0 留给第二阶段。
-
-## 偏离
-
- §7：完成回答、直达校正、输出审核、上下文摘要、T1 本轮不做。
- `usageStartedAt` 用读取函数，在计算 `durationMs` 时才取，因为工厂早于该赋值创建。`selectedModel` 仍是后面的常量，工厂经 `modelSlot` 读取。
- `cancel` 与 `usagePayload` 在 route 留转调用，完成回答的调用点不用改写。
- 行为测试覆盖预留、写满 409、取消把 `request_completed` 当成功、寒暄免费结算、重试 3 次且退避 150/300 毫秒、用量字段。完成回答、直达校正、`settleResult` 只执行一次留在 route，不在本轮行为测试里。
- T4 比较前把 `durationMs` 置 0。这是唯一的归一化。
-
-## 三栏
-
-| 文件 | 原值 | 新值 | 原因 |
-| --- | --- | --- | --- |
-| request-rate-limit | 限额早于 `reserve_consultation_usage` | 限额早于 `reserveCredit`；RPC 在 settlement | 预留体搬走，顺序仍在 route |
-| content-moderation | 审核早于该 RPC | 审核早于 `reserveCredit`；RPC 在 settlement | 同上 |
-| consult-prep-gate | 追加 RPC 早于读标题 | `appendQuestion()` 早于读标题；RPC 在 settlement | 追加搬走 |
-| consult-first-frame | 流内两处 RPC 与 `session_full`；寒暄分支含免费 RPC | 流内是两次工厂调用；正文与寒暄 RPC 在 settlement | 预留、追加、寒暄结算搬走 |
-| consultation-smalltalk | 寒暄分支含免费 RPC | 分支调用 `completeSmalltalk`；RPC 在 settlement | 寒暄结算搬走 |
-| session-title | 切片从追加失败分支起 | 切片从 `appendQuestion()` 起到 `usagePayload` | 失败分支搬走，标题仍在其后 |
-| consult-reports-billing | route 同时引入错误类与定价函数 | route 只引入错误类；定价函数在 settlement | 定价随预留搬走 |
-| chat-session-authority | route 含追加 RPC 与写满文案 | 文案在 settlement；`reserveCredit` 早于 `appendQuestion` | 追加在预留成功之后 |
-| consultation-session-capacity | route 含两处 `session_full` | 两处在 settlement；route 原样返回 | 写满 409 随追加搬走 |
-| consult-latency | route 含 `consultationUsageMetadata` | 该调用在 settlement 的用量函数 | 用量载荷搬走 |
-| application-billing | route 的用量函数含模型字段、合并与 `eventKey` | 这些在 settlement；route 转调用并写入 `p_actual_usage` | 用量载荷搬走 |
-| consultation-stream-recovery | route 含预留 RPC、取消函数体、重试上限 | 这些在 settlement；完成回答的重试仍在 route | 预留、取消、重试助手搬走 |
-
-## 检查
-
-| 检查 | 命令 | 结果数字 |
-| --- | --- | --- |
-| 类型 | `tsc --noEmit -p .` | 退出码 0 |
-| 规范 | `npm run lint` | 退出码 0；0 错误，123 条既有警告 |
-| 定向测试 | `tsx --test` 结算、开流前与读 route 的 24 个文件 | 203 通过，0 失败，0 取消 |
-| 差分 | `consult-route-split-diff.mts` | 16 个场景全部一致；基线 `32b238cf` |
-| 行数差 | `git diff --numstat origin/staging` 加新文件行数 | 见下 |
-
-T4 一致的场景：401、冻结 423、请求体 400、会话不存在 404、校正会话 409、模型变更 409、模型不可用 503、提示词提取 400、输入审核拦截、点数不足 402、session_full 409、寒暄、普通咨询完成、输出审核命中、生成中失败（取消）、直达校正。
-
-对照 `origin/staging` 的增删合计（含本文件）：1384。
-
-## 第二阶段
-
-把完成回答、直达校正、输出审核和上下文摘要搬进同一工厂，再做 T1。之后去掉 route 上的两处转调用，让 `accounting.rpc(` 为 0，并把 `route.ts` 净减做到 450 行以上。

-# PROGRESS · 契约与小工具去重 · 2026-10-13
-
-分支 `codex/contracts-helpers-dedupe-20261013`，基线 `origin/staging` `cd7e0a34933bd288ad7a529d51477c7099e1f6b1`。只搬定义和引用。哈希字节、状态字符串、主题枚举值不变。没有改表、迁移、依赖、`page.tsx`、`scripts/jyotish_api_server.py`。没有写 BUG_HISTORY、CHANGELOG、DESIGN.md。`docs/agents/domain.md` 与 `CONTEXT.md` 里没有 EvidenceDomain，未加术语句。本分支 BUG 最大号 1357，本单没有新缺陷，不占新号。
-
-## 做了什么
-
- T1：报告创建请求的 zod、默认主题、深度枚举收进 `frontend/src/lib/contracts/personal-report-request.ts`。服务端类型用 `z.infer`，客户端发送类型用 `z.input`。原导出名在 route-core、plan、contract 里 re-export。按钮删掉手写 interface。
- T2：校正状态列表与入口类型收进 `frontend/src/lib/contracts/rectification-entry.ts`。线上形状的 status 仍是 `string`。服务端类型在此之上收窄。`case-status.ts` 再导出这些数组，import 无环。客户端解析器仍接受任意字符串 status。
- T3：旧引导流程的 `EvidenceDomain` / `evidenceDomains` 改名为 `LegacyGuidedEvidenceDomain` / `legacyGuidedEvidenceDomains`（数组里的字符串没变）。出生时间证据的 `CandidateResult` 改名为 `LegacyCandidateResult`。`ChoiceKey` 只留在 `probe-explain.ts`（`choice-card.ts` 已经 import 它，反向会成环），choice-card 再导出。`ClaimStatus` 只留在 `personal-report-contract.ts`。v9 的 EvidenceDomain 与快照的 CandidateResult 没改名。
- T4：同义的对象判断和有限数判断收进 `frontend/src/lib/guards.ts`。`sha256Hex` 收进 `frontend/src/lib/hash.ts`（仅服务端）。长文、兑换码、消息正文改为调用它。
-
-## 替换清单（文件 → 共享函数）
-
-调用处多数保留原来的局部名字，用 import 别名接到共享函数。原因见文末「偏离」。别名不是另一份实现。
-
-| 共享函数 | 文件 |
-| --- | --- |
-| `isRecord` | `generate-personal-report-button.tsx`、`personal-report-page.tsx`、`account-deletion.ts`、`skill-package-registry.ts`、`report-public-projection.ts`、`compose-receipt.ts` |
-| `asRecord`（调用名本来就是 asRecord） | `varga-observations.ts`、`refinement-packet.ts`、`inference-adapter.ts`、`confirmation-gate.ts`、`ephemeris-view.ts`、`daily-starlanguage.ts`、`consultation-step-timing.ts` |
-| `asRecord`（别名 `recordOf`） | `subject-birth.ts`、`consultation-subject-resolver.ts`、`chart-subject-write.ts` |
-| `asRecord`（别名 `record`，非数组否则 null） | `birth-profile-timezone.ts`、`chart-view-mapper.ts`、`consultation-route-service.ts`、`general-daily-panchanga.ts`、`personal-report-longform-generate.ts`、`rectification-adopted-chart-tiers.ts`、`reply-quality-capture.ts`、`report-birth-binding.ts`、`v9/engine-client.ts`、`v9/segment-contract.ts`、`personal-report-route-core.ts`、`personal-report-worker.ts`、`personal-report-generation.ts` |
-| `recordOrEmpty`（别名 `record`，非数组否则 `{}`） | `consultation-workflow.ts`、`chart-birth-truth.ts`、`consultation-evidence-card.ts`、`consultation-judgment-table.ts`、`admin/rectification-telemetry-summary.ts`、`report-fact-table-values.ts`、`report-fact-tables.ts` |
-| `finiteNumberOrNull`（别名 `finiteNumber`） | `personal-report-route-core.ts`、`personal-report-worker.ts`、`personal-report-generation.ts`、`rectification-candidate-result.ts` |
-| `sha256Hex` | `personal-report-generation.ts` 再导出；`hashLongformMarkdown`、`hashRedeemCode`、`messageContentHash` 改为调用它 |
-
-## 未合并及原因
-
-| 留下的私有函数 | 原因 |
-| --- | --- |
-| `rectification-candidate-result.ts` 的 `function record` | 数组也当对象，否则 null。与 `asRecord` 不同义 |
-| `geoapify-location-service.ts` 的 `function record` | 数组也当对象，否则 `{}` |
-| `server-owned-birth-profile.ts` 的 `function finiteNumber` | 接受数字字符串，失败返回 undefined |
-| `chart-profiles/route.ts`、`chart-profiles/[id]/route.ts`、`synastry-reports/route.ts`、`admin/admin-error-response.ts` 的 `errorMessage` | 三种错误提取方式，任务书要求不并 |
-| `personal-report-service-core.ts` 的 `PERSONAL_REPORT_DEPTHS` | 名字和用途都不是 T1 的 `REPORT_DEPTHS`，没有硬合 |
-
-任务书 §2.3 把「含数组否则 null」记在 `rectification-adopted-chart-tiers.ts`。当前 staging 上该函数已经排除数组，所以并入 `asRecord`。真正含数组否则 null 的那份在 `rectification-candidate-result.ts`，保留。
-
-## 断言
-
-| 原值 | 新值 | 原因 |
-| --- | --- | --- |
-| `workflow.indexOf("function record(")` | `workflow.indexOf("function rectificationBoundaryFromGate(")` | 非数组否则空对象的私有 `record` 已删除。切片终点改到紧随其后的既有函数。锁住的 schema 字段没改，`chart: z.record(z.unknown())` 仍在 |
-
-文件：`frontend/tests/consultation-workflow-contract.test.ts`。其余点名测试没有改断言。
-
-## 仅 import
-
-这些文件只改了 import 行，esbuild 转译结果与 staging 相同：
-
-`rectification-choice-card.tsx`、`rectification-message-entry.tsx`、`use-rectification-case-snapshot.ts`、`answer-choice.ts`、`block-scan.ts`、`choice-action.ts`、`turn-intent-classifier.ts`、`turn-question.ts`、`window-widen.ts`、`rectification-chat-choice-run.ts`。
-
-## esbuild 差分
-
-对 `frontend/src` 里每个改动文件，用 esbuild `transform`（`.ts` / `.tsx`，`format=esm`，不打包）对比 `origin/staging` 与工作区。结果：相同 26，有差异 49，新文件 4，转译失败 0。
-
-新文件：`contracts/personal-report-request.ts`、`contracts/rectification-entry.ts`、`guards.ts`、`hash.ts`。
-
-有差异的原因，按文件：
-
-| 文件 | 原因 |
-| --- | --- |
-| `generate-personal-report-button.tsx` | 手写请求类型删除，默认主题改为从 contracts 取值 |
-| `personal-report-page.tsx`、`account-deletion.ts`、`compose-receipt.ts`、`report-public-projection.ts`、`skill-package-registry.ts` | 本地 `isRecord` 删除，改为 import |
-| `consultation-step-timing.ts`、`daily-starlanguage.ts`、`ephemeris-view.ts`、`confirmation-gate.ts`、`inference-adapter.ts`、`refinement-packet.ts`、`varga-observations.ts` | 本地 `asRecord` 删除，改为 import |
-| `subject-birth.ts`、`consultation-subject-resolver.ts`、`chart-subject-write.ts` | 本地 `recordOf` 删除，import `asRecord` 并别名为 `recordOf` |
-| `birth-profile-timezone.ts`、`chart-view-mapper.ts`、`consultation-route-service.ts`、`general-daily-panchanga.ts`、`personal-report-longform-generate.ts`、`rectification-adopted-chart-tiers.ts`、`reply-quality-capture.ts`、`report-birth-binding.ts`、`engine-client.ts`、`segment-contract.ts` | 本地「非数组否则 null」的 `record` 删除，import `asRecord` 并别名为 `record` |
-| `consultation-workflow.ts`、`chart-birth-truth.ts`、`consultation-evidence-card.ts`、`consultation-judgment-table.ts`、`rectification-telemetry-summary.ts`、`report-fact-table-values.ts`、`report-fact-tables.ts` | 本地「非数组否则空对象」的 `record` 删除，import `recordOrEmpty` 并别名为 `record`。`z.record(...)` 没改 |
-| `rectification-candidate-result.ts` | 只把「有限数否则 null」改为 import。含数组的 `record` 仍在文件里 |
-| `personal-report-route-core.ts`、`personal-report-worker.ts` | 同上，再加上 schema / 调用处的 guard import |
-| `personal-report-generation.ts` | guard 搬家，并且 `sha256Hex` 改为从 `hash.ts` 再导出 |
-| `personal-report-longform-appendix.ts`、`supabase/codes.ts`、`message-origin.ts` | 哈希函数体改为调用 `sha256Hex`。输入仍按 utf8 |
-| `personal-report-plan.ts`、`personal-report-contract.ts` | `REPORT_DEPTHS` 字面量搬到 contracts，本文件 re-export |
-| `case-status.ts` | 状态数组搬到 contracts，本文件 re-export。数组内容相同 |
-| `rectification-entry.ts` | 本地状态列表删除，Set 改用共享常量 |
-| `birth-time-question-planner.ts`、`birth-time-journey-turn.ts`、`birth-time-journey-transitions.ts`、`birth-time-journey-turn-persistence.ts`、`birth-time-journey-case-loader.ts` | 运行时常量改名 `legacyGuidedEvidenceDomains`。不打包，所以导出名出现在转译结果里。数组里的字符串没变 |
-
-相同的 26 个文件里，上面「仅 import」10 个只动了 import。其余是类型改名或类型再导出，类型擦除后转译结果与 staging 相同（含 `open-request.ts`、`choice-card.ts`、`report-evidence-bundle-v2.ts`、`birth-time-evidence.ts` 及其余 Legacy* 引用）。
-
-## 测试
-
-开工没有跑全量 `npm test`（本轮不做全量，也没有新的全量基线数字）。完工数字：
-
-| 检查 | 命令 | 结果 |
-| --- | --- | --- |
-| 类型 | `frontend` 下 `tsc --noEmit -p .` | 0 错 |
-| 规范 | `frontend` 下 `npm run lint` | 0 错，123 条警告。警告是原来就有的。本轮删过 `personal-report-worker.ts` 里不再使用的 `JsonRecord`，没有留下新警告 |
-| 改到的测试与任务书点名的测试 | `node node_modules/tsx/dist/cli.mjs --test`（guards、报告入口、首页校正解析、校正契约、报告生成与长文哈希、咨询 workflow 契约、出生时间改名相关） | 209 通过，0 失败，0 取消，0 跳过 |
-
-没有跑前端全量 `npm test`、Python 快速门、`test:db`。`supabase/codes.ts` 只改了哈希函数体，没有改查询、表或迁移。
-
-## 偏离
-
-1. 调用处没有改成共享函数名，改用 import 别名。把调用处全部改名时，已跟踪 diff 为 621 增、852 删（合计 1473），加上当时的新文件 248 行，约 1721 行，超过硬红线 1500。别名之后已跟踪 diff 为 229 增、461 删。共享函数仍只有 `guards.ts` / `hash.ts` 里的那一份。
-2. 报告按钮是客户端组件，但它要取值 `DEFAULT_REPORT_THEMES`，而这份常量和 zod schema 在同一个文件。因此这个按钮会把 zod 带进自己的包。任务书允许「zod 已在该组件 bundle 内」的例外；首屏 gzip 由验收侧看。测试仍从按钮 re-export 引用该常量。
-3. `LegacyCandidateResult` 的引用比任务书点名的文件多（向导、旅程加载等）。不改的话 `tsc` 会报错，所以一并改了类型名，没有改运行时值。
-4. 含数组变体的文件名与任务书 §2.3 不一致，以当前 staging 的函数体为准，见上表。
-
-完工 diff：已跟踪 229 增 + 461 删，新文件与本记录 345 行，合计 1035，低于 1500。
