+HEL-827 后端交付与接线契约
+
+基准 v1.10 / 59 项。读取提交 `2d97050c7e86f909590ffdec3e8bc1aa5627cade`（已审 A1/A2/A3）。施工前 fetch 后四个引用与派卡一致：main `3a986726d8593e0ed2274f79db6cc5d807d2ebf0`；产品目标 `origin/agent/agent/de8874a3803b` / `db571ba204c8372989f96e1ed9b5cd00d3a306c7`；hel-825-review 为读取提交；hel-826-continuation `71660155cb4b17705a6b7400820ecfb35bb11895` 仅作材料来源。本分支保留全部已审前端，不合并 PR，不替换产品线。
+
+## 实现与原意核对
+
+- `memory/store.py`、`memory/r2.sql`：只增表/列/索引；迁移的列检查在 SQLite 写锁内执行，保留有内容的 R1 life_event 与原始身份、八字、聊天、记忆。唯一 run_id 对应一条事件。
+- `life/runtime.py`：服务端 lifespan 内单一循环，退出取消并 join；关网页不影响它。四个本地窗口，从 character.yaml 的 day_start_hour 开始每隔4小时一个，每窗口一小时。每窗口最多一次，正常最多4条/日；失败或停机会减少，绝不补足指标。IANA 时区可配置，隔离默认 Asia/Shanghai，未替用户选城市。
+- `life/model.py`：复用获准 provider、scene 路由和温度；人格走 dialogue_followup（standard），生活走 life_event（low），判定走 output_guard（low），成长走 fact_extract（low）。JSON 严格校验，错误/截断/超时无模板。背景调用先保守预留用量，持久化预算；0.7警告，预计达到0.95则拒绝新背景调用。主对话保留原预算降档语义。预算日期沿用已有 BudgetGuard 的服务器日期，与城市选择无关。
+- `life/sharing.py`：完整成功轮次、final 的随机凭证与全文摘要确认、后置实际讲述判定三者齐全才发布；`telling_log` 与 told 同事务。一次判定可有4个事件，以 `(event_id,message_id)` 去重，消息级判定另存；包含判定原文证据、模型及时间。客户端不能指定事件集合。
+- `life/public.py`：统一守卫与字段白名单；life WHERE told=1 后分页，详情未知/未分享/未知状态/伪造 ID 同形404；消息只返回允许的 lifeIds，凭证与候选永不进历史响应。保留原消息正文语义：她已说出的对话文字不作为结构化生活发布证明。成长只从公开生活或已确认、判定完成且全部候选已公开的成功对话提炼；未知来源拒绝。
+- `life/persona.py`：bazi_core 原始事实每轮独立注入，先预留 system 空间，再缩减近轮历史；不再把六段静态解释充作人设。persona_interp 是稳定的自主理解，persona_seed 是3–5条初始习惯，growth_event 另存真实来源与实际生成时刻。诠释与习惯同事务；并发、失败重试不会造多份。PATCH关系不触及这些层。
+
+CG-013 原话「系统级的，不能修改」及 CG-014「模型会有自己的思考和理解」同时保留：事实只读，但没有固定每次回答的标准。CG-015 的“同意推荐”对应带少量自主初始特点、后续另存成长；不能把它当作允许改八字。AM-001 的「等她讲过才显示」按服务器守卫实施，未把附件中 yield final 当作已收到，也未照抄 UNIQUE(message_id) 的多事件缺陷。UX-004 的深度整改不以六段解释或浅标签代替。本轮没有需求变更，也没有宣称完整 R2 或产品验收。
+
+## 开关、运行与恢复
+
+默认不开自动生成。只有后续获授权的隔离服务设置 `CYBERGRIL_R2_ENABLED=1` 才运行循环与新建档案人格生成；`CYBERGRIL_LIFE_TIMEZONE` 配置 IANA 名称。不改 models.yaml、认证或运行时绑定。仍为已有单进程单 worker 服务，不启用 reload/多 worker；台账抢占额外防止并发执行者重复生成，不能据此宣称多 worker 的 epoch/chat 协调已实现。
+
+生成抢占使用 INSERT OR IGNORE 的实际插入结果，不根据 pending 判断谁能执行。owner 随机令牌和40秒 lease 配合，模型调用30秒上限。未过期 pending 不偷取；崩溃过期 pending 变 skipped/lease_expired，同窗口永不重生成。晚到旧 owner 不能写事件。正常取消将本轮 slot 置 skipped。last_scan 持久化，停机错过的窗口只记 skipped/outside_window；首次启用只记当日先前窗口，不虚构启用前的历史。恢复时只执行当前窗口，不补生成错过的几天。
+
+台账键为 `(tz,day_key,slot)`；时区是命名空间，切换不会撞旧键，不改旧事件日期。事件 ts 是生成完成的实际墙钟，事件 day_key 按这个时间及当时的 tz 计算；不能拿重启时间或新城市时区重写旧事件。跨区切换的作息策略及城市 UI 留 R6；重复 DST 小时按同一本地日期/slot 仅生成一次。
+
+连续3次真实生成错误将持久暂停；仅重启不会清除暂停。预算不足不补造事件。公开 health 的 life_runtime 只给状态、时区、预算布尔值和最近 slot 的通用原因，不带内容、关键词、提示词或错误正文。人工质量判断与解除暂停由后续隔离审核负责，本卡不留后台程序长跑。过期判定 claim 终止为 failed，不猜结果；事件可在未来另一完整轮次真正讲述并确认后再发布。
+
+## 给视觉总监的后端契约（本卡未改 web）
+
+| 接口 | 字段和语义 |
+| --- | --- |
+| GET `/api/life?limit=50&before=<id>` | `{events, next_before, epoch}`。limit 1–100；before 1–9223372036854775806；只在已公开集合上降序分页 |
+| GET `/api/life/{id}` | `{event,epoch}`；未知/未分享/非法/不存在统一404 `{"detail":"这一条现在打不开。"}` |
+| life event | `id:number,ts:unix-ms,kind,content,place,salience,source,day_key,tz,told:true,told_at,messageIds:number[]`。无候选或未分享信息 |
+| GET `/api/messages` | 原字段不变，增加裁剪后的 `lifeIds:number[]`；从不返回确认凭证或候选 ID |
+| GET `/api/persona` | `{state,interpretation,seeds,growth}`；字段形状见下；不存在伴侣404 |
+| POST `/api/persona/retry` | 仅重试本版本新建档案的已建任务，旧档案409；失败不返回虚假模板 |
+| GET `/api/health` | 原 capabilities.life 保持 false（本卡未接前后端）；`backend:{life,persona,receipt,web_connected:false}` 与 life_runtime 提供后端状态，不能冒充完整接通 |
+
+`persona.state` 为 `ready/loading/failed/disabled/not_initialized`。新建时请求在有界人格生成后返回；并行 GET 可看到 loading。失败后档案仍保留，可显式 retry；旧档案 never auto backfill，显示 not_initialized。interpretation 为 null 或 `{id,text,pillars_hash,model,created_at,provenance}`；seeds 为 `{id,text,created_at,provenance,interp_id}[]`；growth 为 `{id,ts,source,ref_id,text,model,created_at}[]`。公开字段作为一组裁剪；不要把旧六段解释移入“她怎么理解自己”冒充模型生成。
+
+已有档案补建仅提供 `scripts/r2_backfill_persona.py --db <单独授权数据库> --authorize-core-sha256 <核对后的指纹>`。本卡仅对合成旧档案验证，不对8310/8320运行该脚本；脚本不是远端管理入口。补建写 `backfilled-R2` 和实际生成时间，前端需注明「后来补上的初始印象」。关系修改仍只改关系，不重生人格。
+
+## 客户端完整接收确认
+
+SSE 原 chat.delta/final/error、turn_id、epoch 语义保留。成功 final 增加可空 `receipt`；旧客户端忽略它时不发布任何生活事件。新客户端须先经过原 TurnGate，只有完整解析 final、全文已接收且未 abort，才确认。不要对 delta、error、取消轮次或仅历史列表发确认。
+
+```json
+{
+  "t":"chat.final", "epoch":7, "turn_id":"<UUID>",
+  "utterance":{"text":"完整回复","speech_tags":[]},
+  "receipt": {
+    "message_id":42, "turn_id":"<同轮UUID>", "epoch":7,
+    "token":"<43字符随机凭证>",
+    "text_hash":"<完整回复UTF-8的SHA256>", "expires_at":1792886400000
+  }
+}
+```
+
+客户端从完整 `utterance.text` 自行计算 SHA256，核对 receipt.text_hash 后 POST `/api/chat/received`：
+
+```json
+{"message_id":42,"turn_id":"<同轮UUID>","epoch":7,"token":"<凭证>","text_hash":"<客户端算出的SHA256>"}
+```
+
+只允许这五个字段；禁止 event_id/event_ids。成功 `{accepted:true}` 仅表示确认被接受，可能还在等判定，不等于事件已公开。判定与确认任意顺序都可，最后一个条件完成时事务提交；后台每轮最多处理一条待判定消息。格式错误422，绑定不符/伪造/过期/不存在统一404。24小时有效，重复确认幂等。凭证只在完整 final 中发送，不从 health、messages 或 persona 获取。
+
+重放成功轮次不会重调主模型或重判：它返回原全文和原 receipt，外层 epoch 是当前服务 epoch，receipt.epoch 保留成功消息的 epoch。客户端同步新 epoch 后可重放同 turn+同用户文本，重新核验完整 final，再用 receipt 内原 epoch 合法重试确认。服务重启前已经接收的合法凭证也可在有效期内重试；这不是放宽当前 chat 请求的 epoch 检查。尚未开始的判定可重启后继续；判定中崩溃并过 lease 的消息终止判定，宁可不发布，不能拿客户端重试冒充成功判定。
+
+这证明持有完整 final 的接收方明确确认了全文；不声称能通过网络协议证明人类实际阅读，也没有新增 LAN 鉴权体系。
+
+## 隐私夹具与 R3 接缝
+
+`tests/test_r2.py` 中 `SECRET` / `add_life` 可执行地植入独特私密关键词；覆盖绕过前端直查 life 列表/详情、非法ID、messages 引用、persona/growth 和 health。可导入 `PublicView.allows/references/growth/chat_source_allowed` 复用；服务端必须先确定允许集合，再计算分页、摘要、搜索及回忆。未知分享状态和未知来源拒绝，不能只在前端调用 publicView。
+
+本卡未创建 `/api/memories`、搜索、摘要、FTS/R3 回忆接口。这些路径没有被测为通过。未来实现者须在实际端点植入同一关键词、按真实请求断言不返回它；关联回忆包含任一未公开 lifeId 时整条拒绝，不能剥引用后保留其派生正文。正文/摘要/关键词/关联字段应一起受守卫约束。
+
+## 非破坏迁移与回滚
+
+迁移可重复，未 drop/recreate 任何旧表；测试保留实际有行的 R1 schema、名字/生日/聊天/底色指纹。只有新增层与运维台账写入，PATCH关系前后全部人格层指纹不变。诠释/种子和 told/log 的写入分别注入磁盘异常，验证事务回滚无半份。
+
+回滚兼容 R1：旧代码不读取新增表/列；可停止新版本、回到原 release，仍使用同一 DB。不得为了回滚删库或删新增资料。未来再启用 R2 时扫描台账，pending 按上述恢复规则处理，不重造已完成 slot。真实部署前备份/切 release/服务操作归总工；本卡没有执行这些操作，也没有对8310/8320迁移或补建。
+
+## 真实模型核验与质量边界
+
+`model-smoke-HEL-827.json` 保存一次四调用有界核验：standard 人格+习惯、low 生活、low 正向实际讲述判定、low 同词/非经历排除，共33.77秒，保守计账8491。输入全为本地合成人物，临时 DB 随脚本结束清理，未创建服务。接收确认未伪造成浏览器测试，生活样例始终 told=0。报告中 life 的 synthetic-smoke 是当次隔离调度标签；最终实现已改为事件 day_key 按完成墙钟日期计算，并用压缩时钟测试检查时区/日期。
+
+预检曾收到网关400 `No user query found in messages`：修复 structured 的请求契约为 system指令+user数据后执行上述一次核验；没有改模型、温度、认证或开启调参。额外预检只用极短JSON测试定位400。此证据仅证明结构契约可用，不证明人格长期质量或生活内容验收。样例出现第三人称“它”和办公楼茶水间情境，须交总工核对世界观/叙述质量；本轮到此停止真实调用，不把四个结构检查的 true 当成内容验收。
+
+## 未完成承接
+
+视觉总监下一卡：life/persona真实字段绑定、receipt确认接线与真实浏览器重放/取消验收；继续保留已审场景/阅读效果。总工：独立审核、隔离部署、内容质量抽检，前端接线后安排真实连续3天每天1–4条、关网页仍生成的隔离长跑；压缩时钟仅证明机制。本卡无长跑服务留存。
+
+R3跨日记忆/FTS，R4主动联系/返回同步，R5连续语音，R6城市天气/素材/完整备份，R7授权观察，以及真实视频首尾衔接/口型仍由主卡承接。现有近20轮不叫长期记忆。没有浏览器接线、Safari/Firefox/真机新验收；没有部署、合并PR、访问4080或读用户聊天/档案。

+HEL-827 实测记录（2026-10-24，隔离本地数据）
+
+- 完整 Python：`python -m pytest -q` → **191 passed，7.82秒**，原142项（其中旧六段模板注入断言按新要求换成已保存原始事实注入）+49项R2反例。完整输出见 `pytest-HEL-827.txt`。仅既有 Starlette TestClient 弃用提示；未安装建议的新依赖。
+- R2包含：有内容旧schema升级与重复迁移、所有身份/八字/聊天保留；两独立SQLite连接并发抢占；重启/停机不回填；时区切换旧日期不动；预算警告/硬停/重启不清零；连续失败持久暂停无模板；无浏览器请求服务循环推进；生命周期退出取消并收回pending任务。
+- 披露：完整final但无确认不公开、确认/判定两种顺序、同轮多事件、重放不重判、重启合法确认；token/epoch/message/turn/摘要伪造、过期、判定中断、候选外ID/重复ID/不存在原话、错误/截断/length结束/真实loopback部分流断线均不误公开。told/log写入注入异常后两者一起回滚。客户端额外event_ids被拒绝。
+- 隐私：植入独特关键词，直接HTTP列表/详情/伪造ID/messages/persona/health无事件泄漏；隐藏与未知分享状态等形404；已公开集合分页；手工植入隐藏事件旧引用仍被裁剪；隐藏来源或未知来源成长不可见。尚不存在的摘要/搜索/回忆端点没有测试通过声明。
+- 人格：自主诠释与种子同时落库，失败/并发/重试不重复；种子写入故障时连同诠释一起回滚；合成旧档案默认不补建，显式补建真实时间与backfilled-R2；关系更新前后人格/底色指纹不变；每轮完整原始事实独立预留system空间。非模板真实模型样例见独立JSON，内容质量未验收。
+- Python lint：`ruff check src/cybergril/api/app.py src/cybergril/life src/cybergril/memory/store.py tests/test_r2.py tests/test_birth_view.py scripts/r2_model_smoke.py scripts/r2_backfill_persona.py` → All checks passed。
+- 原web：`npm run build --prefix web` → TypeScript检查及Vite构建通过；`npm test --prefix web` → 3 files / 26 tests passed；`npm run lint --prefix web` → 0 errors、2个基线已有warning（ChatPanel的ref清理、ManagePanel无用disable），不替视觉作者修改。web源码零diff，没有新演示联网路径；本轮未复做浏览器/真机或视觉验收。
+- 真实模型：四调用33.77秒；详见 `model-smoke-HEL-827.json` 与交接说明的质量边界。只用已获准配置，对本地合成资料生成；没有读用户资料、改认证或换模型。预检HTTP400的协议问题已定位修复，没有无限调参。
+- 运行状态：只读GET 8310/8320 health都200，epoch分别3/4，llm ok、仍仅text能力；未读取其companion/messages，不部署、不迁移、不补建已有档案。
+- 需求结构：`python3 scripts/check_requirements.py --base-ref origin/main --handoff docs/requirements/handoff-HEL-827.json` 与实际目标 `origin/agent/agent/de8874a3803b` 均通过，59项。结构不替代授权语义和体验。
+- `git diff --check` 干净。没有新依赖，复用既有Python3.12测试环境与锁定node_modules；默认python3为3.10不符合项目>=3.11要求，未用其失败结果作为回归判断。
+- 没有新前端接线、真实三天运行或部署验收；所有本轮测试服务与模型请求均已结束。没有留下长跑程序。内容/世界观质量由总工审阅样例，前端确认接线由视觉总监承接。
+
+仓库只有SSH读写凭据，无Gitea/Forgejo/GitHub API token、git credential helper或gh/tea工具，故交候选分支和提交，不伪造PR。PR目标仍为 `agent/agent/de8874a3803b`，不得改成main。
