+# PROGRESS · 个人报告写作阶段 report_schema_invalid（2026-09-02）
+
+任务书：`TASK-report-section-writer-failure-20260902.md`（`838d9e76`）
+分支：`codex/report-writer-failure-20260902`
+基线：`origin/staging` @ `838d9e76`
+
+开工前置：已读 `docs/research/pre_work_error_ledger.md`、`frontend/AGENTS.md`；`docs/BUG_HISTORY.md` 检索 BUG-352 / 451 / 486–489 / 495。按任务书从 `origin/staging` 建独立 worktree，不碰原仓脏树。
+
+隐私：下文只有错误码、token 计数、`finishReason`、时间戳与 request UUID（任务书已公开）。无 prompt、bundle、模型原文、姓名、出生资料或账号标识。

+
+## 任务 0 · Staging 实证（门控）
+
+取证主机：staging `118.26.111.127`，路径 `/opt/jyotisha-staging`。Postgres 容器 `jyotisha-staging-postgres-1`。
+
+### 日志窗口丢失
+
+取证时公开 staging health 仍指向 `35688015`（`838d9e76` 的父提交）。Web 容器在 `2026-09-02T14:00:21Z`（22:00 +08）被 recreate，与任务书提交 `838d9e76`（`14:00:43Z`）几乎同时。事故窗口（13:19–13:21 UTC）的 `docker logs` 已不在。`[personal-report-agent]` 与 `[personal-report] generation_failed` 无法回收。`usage_ledger` 对该 requestId 为 0 行。
+
+因此 **不能** 用本事故的 `finishReason` / `outputTokens` 分布来确认「主嫌 · 截断」。截断判定只能写 `blocked`。
+
+### 事故行（requestId `77b79067-bd70-465e-ac23-adc4500d4738`）
+
+| 面 | 结果 |
+|---|---|
+| `personal_reports` | `failed` / `report_schema_invalid` / created 13:19:23 UTC / updated 13:21:38 UTC |
+| `personal_report_jobs` | `failed` / `last_error_code=report_schema_invalid` / phase `failed` / **progress 43%** / attempt **1 of 3** / finished 13:21:38 UTC |
+| `theme-career` | **blocked**，attempts **2/2**，`last_error_code=section_evidence_insufficient`，updated 13:21:38.398 UTC |
+| `theme-marriage` | pending，0 attempts |
+| `theme-timing` | pending，0 attempts |
+| `theme-wealth` | pending，0 attempts |
+
+43% = `30 + floor((1/4)*55)`：career 被 block 后第一次 `onProgress`。Job 在 career block 后约 39ms 结束，其余三章从未 `start`。
+
+历史 `report_schema_invalid`（08-30 起，与任务书 5 个小时一致）：跨这些小时的 section 行里，本事故是唯一一条 blocked + `section_evidence_insufficient`。其余为 pending 或 ready。
+
+### 定案
+
+1. **主嫌（CJK `/2` 截断）未证实。** 落库码不是 `section_output_truncated`。截断在 writer 路径通常会变成 `PersonalReportAgentOutputError("report_schema_invalid")` → `section_output_invalid`。本事故没有 telemetry，不得写成 `finishReason=length`。
+2. **次嫌（evidenceRefs 回显）是 career 章的最佳解释。** 旧 `classifySectionErrorCode` 把任何含 `"evidence"` 的消息打成 `section_evidence_insufficient`。`report_writer_evidence_refs_mismatch` 含子串 `evidence`，会被误分类。career 2/2 次、约 29s，符合 assert 失败 + 一次 repair，而不是四章长输出截断。
+3. **第三层：首章 blocked 后没有继续写其余章。** 产品测试已要求其他章仍应交付。Job 以不可重试的 `report_schema_invalid` 失败（attempt 1/3），说明 worker 收到了 `{status:"failed"}` 或 `invalid_request`/`storage_invalid`，而不是 retryable 抛错。无日志无法闭合「是 filter / onProgress / 其它未捕获抛错」。本轮仍把每章失败隔离开，避免一章 throw 中止整份。
+
+`all_sections_blocked` 原先裸 `return`、不走 `failSchema`，因此即使日志还在，也可能看不到 `generation_failed`。本轮改为走 `failSchema`。
+
+任务 1 仍按任务书授权落地中文口径公式，校准用的是 **08-30 任务 0** 的整份调用观测（`outputTokens=3069`，`finishReason=stop`），**不是** 本事故。research / deep 的 3072 cap 保持不变；若以后实测需要更高，另开任务。
+
+---
+
+## 任务 1 · CJK 输出预算
+
+禁止 `targetCharacters.max / 2`。
+
+口径：`1` 中文字符 ≈ `1.3` token（`CJK_OUTPUT_TOKENS_PER_CHAR`）。
+
+章节结构余量 `568`（narrative 之外的 title / actions / caveats / refs / JSON 外壳）：
+
+| 部分 | 估算 |
+|---|---|
+| title ≈ 80 字 | `ceil(80 × 1.3) = 104` |
+| 3 条 actions ≈ 120 字 | `156` |
+| caveats ≈ 80 字 | `104` |
+| evidenceRefs JSON | `80` |
+| JSON 键与括号 | `124` |
+| 合计 | `568` |
+
+摘要结构余量 `580` **已经包含** headline / priorities / JSON，不再把 headline 算第二次：
+
+`ceil(2000 × 1.3) + 580 = 2600 + 580 = 3180`
+
+章节：`min(3072, max(1024, ceil(maxChars × 1.3) + 568))`
+
+| 深度 | max 字 | 未封顶 | 落地预算 |
+|---|---|---|---|
+| concise | 500 | 1218 | **1218** |
+| standard | 1200 | 2128 | **2128** |
+| deep | 2000 | 3168 | **3072**（cap，缺口 96 token） |
+| research | 2800 | 4208 | **3072**（cap；约合 narrative 2504 字，低于 2800 上限） |
+| summary | 2000 字段 | 3180 | **3180**（cap 4096） |
+
+08-30 整份 writer 一次调用 `outputTokens=3069` 且 `stop`，说明 3072 能装下一份大 JSON。本事故未证实截断，因此不把 cap 自行抬高。length 修复重试：同一 `outputBudget`（不得低于首次），提示词要求压到 `targetCharacters.min` 并闭合 JSON。
+
+---
+
+## 任务 2 · evidenceRefs 回显
+
+- `sectionPrompt` 增加：`evidenceRefs 必须逐字复制 plan.evidenceRefs 数组，不得增删`。
+- `assertWriterOutput` 仍是 id/theme 全等 + refs **集合相等**，语义未放宽。
+- Repair 只拼类别词：`identity mismatch` / `refs mismatch` / `schema invalid` / `output truncated`。refs 类再次重申逐字复制。不把 ref id、正文或 bundle 拼进 repair。
+- `classifySectionErrorCode` 先匹配 identity / refs，再匹配泛化 `"evidence"`，避免再把 refs mismatch 写成 `section_evidence_insufficient`。
+
+---
+
+## 任务 3 · 失败可观测
+
+不改表。应用层聚合已有 `personal_report_sections` 行。
+
+- 详情 API：`failureSummary`、`innerReason`（`all_sections_blocked` 或 `section_generation_incomplete`）、`sectionErrorCodes`。
+- 列表 API：失败行多查 `request_id, status, last_error_code`（无正文），写入 `failureSummary`。
+- 报告中心：`failureSummary ?? failureCode`。详情页摘要为主文案，等宽错误码为辅。
+
+本事故若用新摘要，应接近：「4 个主题中 1 个写作失败：证据引用未对齐，3 个未开始」。旧码仍会显示「证据不足」，因为历史行的 `last_error_code` 不会回写。
+
+---
+
+## 任务 4 · 真实验证
+
+**未做。** 等任务 1–3 进入 staging 且 `GET https://staging.jyotisha.chat/api/health` 的 `.deployment.gitCommit` 对齐后再跑：standard `personal_full` 四章正文、telemetry 无 `length`、≥3 处 writer→bundle 回溯、每章 token/墙钟对照 `PROGRESS-report-skill-parity-20260901.md` 的 2 倍线。不提升 main。
+
+---
+
+## 质量门
+
+| 门 | 结果 |
+|---|---|
+| `frontend/node_modules/.bin/tsc --noEmit` | 通过（exit 0，无输出） |
+| `eslint`（改动的 TS/TSX 文件） | exit 0，无 error 输出 |
+| 聚焦 `tsx --test`：plan / writer-failure / generation-v2 / api / view / agent-telemetry | 104 pass / 0 fail |
+| 复跑 api + writer-failure | 53 pass / 0 fail |
+| `personal-report-generation.test.ts` + `personal-report-worker.test.ts` | 51 pass / 0 fail |
+
+未跑全量 `tests/*.test.ts`，不声称全套绿。未改 `.gitea/workflows/**`，未提升 main。

+## BUG-496 | 个人报告写作失败被压成 report_schema_invalid，首章失败后其余主题未开始
+
+- 状态：resolved
+- 首次发现：2026-09-02
+- 最近更新：2026-09-02
+- 影响面：`generateSectionedPersonalReport`、`createPersonalReportAgent`、`classifySectionErrorCode`、`GET /api/reports`、`GET /api/reports/[reportId]`、报告中心失败卡片
+- 用户现象：blocked-repairs 部署后，真实 `personal_full` 仍显示生成失败，可见码只有 `report_schema_invalid`。四主题里只有事业章留下失败记录，婚恋/财富/应期未开始。
+- 触发条件：章节 writer 输出未通过 `assertWriterOutput`（常见为 `evidenceRefs` 与 plan 集合不等），或输出在 token 预算内被截断；随后整份报告失败。
+- 根因：三层叠加。旧错误分类把任何含 `evidence` 的消息打成 `section_evidence_insufficient`，`report_writer_evidence_refs_mismatch` 被误标；章节输出预算用英文「字符 ÷ 2」，standard 上限 1200 字中文只分到 1024 token；一章 blocked 或未捕获抛错可以中止整份，job 停在约 43%。失败详情只有聚合码，页面无法区分截断、引用不齐或未开始。staging 事故窗口的 writer telemetry 在容器 recreate 后丢失，本事故不能写成 `finishReason=length`。
+- 修复：中文口径重算每章/摘要 `maxOutputTokens`，去掉 ÷2；length 修复要求压到字数下限且预算不低于首次。Prompt 要求逐字复制 `plan.evidenceRefs`；repair 只加失败类别。refs/identity 先于泛化 `evidence` 分类。单章失败后继续其余主题；`all_sections_blocked` 走统一失败日志。详情与列表聚合已有 section 行，展示可读摘要与错误码，不改表、不放宽 writer schema。
+- 验证：预算表锁定 concise 1218 / standard 2128 / deep 3072 / research 3072 / summary 3180。refs mismatch 分类为 `section_refs_mismatch` 且其余主题仍交付。repair 提示含类别词、不含内容。失败详情从 section 行汇总。`tsc --noEmit`、改动文件 ESLint、个人报告聚焦测试。
+- 防复发：输出预算不得再用字符 ÷ 2。`assertWriterOutput` 保持 id/theme 全等与 refs 集合相等。section 错误码不得把 refs mismatch 归进 evidence insufficient。一章失败不得中止其余 write 主题。用户可见失败必须有错误码级摘要，不得只展示 `report_schema_invalid`。日志与 PROGRESS 不得写入 prompt、bundle、模型原文或用户资料。
+- 相关记录：BUG-352、BUG-451、BUG-486、BUG-489
+- 复发自：BUG-451（分章后仍把写作失败压成整份 schema 码，截断预算与失败分类未按中文口径收口）
