+# 切片 11：不确定代码审计、全量验收与交接准备
+
+> 基线：`dec3cd12365df5e7d4c391369f14c457cf56d7d9`
+> 候选回档标签：`xiaobai-preservation-slice-11-candidate-20260731`
+> 当前结论：自动验收完成，等待用户人工验收；尚未执行正式切换、Docker或NAS部署
+
+## 1. 本切片做了什么
+
+本切片不增加功能、不调整视觉，也不继续拆分业务代码。它逐项审计切片10保留的待定资产，
+把有完整证据的无效实现放入可单独回档的试删候选，并为人工接管和后续切换准备文档。
+
+试删候选：
+
+- `app/demo_data.py`：没有运行导入、动态注册、数据库或配置责任的旧演示数据构造器。
+- `app/frontend/heaven-loading.js`：页面未加载的旧问天动画；正式入口继续使用
+  `frontend/pages/heaven/loading-v2.js`。
+- 五个只有定义、没有消费者的前端函数：`commonReviewColumns`、`outcomeClass`、
+  `screenerResultMatchesSelection`、`selectRegime`、`showHeartRitualCurtain`。
+
+明确保留：
+
+- `wencai_saved_queries`表及三个Repository方法。它们承担历史数据库兼容和用户隔离责任，
+  当前库为空不能证明其他部署库也为空。
+- 与试删函数相邻但证据不足的DOM、状态字段和CSS。没有为追求行数继续连带删除。
+
+逐项指纹、引用扫描、责任判断和恢复位置见`uncertain-code-audit.md`。
+
+## 2. 自动验证结果
+
+| 验证 | 结果 |
+|---|---:|
+| 原版`python -m unittest discover -s tests -q` | 231项通过 |
+| 迁移版`python -m unittest discover -s tests -q` | 298项通过 |
+| 历史切片与前端/清理专项复核 | 通过 |
+| 迁移版JavaScript语法检查 | 24个文件通过 |
+| `npx.cmd playwright test --reporter=dot` | 45项通过（1.6分钟） |
+| 固定只读API差分 | 21个端点全部一致 |
+| 数据库差分 | 62个schema对象、21张关键表全部一致 |
+| `git diff --check` | 通过 |
+
+早期切片的五个前端源码测试原本要求与未试删的`static/app.js`逐字符一致。本切片把它们统一到
+`preservation_helpers.assert_frontend_runtime_matches_audited_baseline`：只允许审计登记的五段原始
+行号被删除，任何其他新增、删除、重排或内容变化仍会使全部历史测试失败。
+
+完整API和数据库结果分别见`api-diff.json`与`database-diff.json`，二者`all_equal`均为`true`。
+
+## 3. 真实浏览器验收
+
+- 桌面端复核情绪周期、智能选股三个工作区、问天日间/夜间和加载资源；控制台无新增
+  error或warn，页面无横向溢出。
+- 问天只加载`/pages/heaven/loading-v2.js`，未请求已试删的`/heaven-loading.js`。
+- 观势、观气、观心星空与八卦节点、原动画名称和可见行为保持不变。
+- `390x844`逐一点击涨停池、智能选股、问师、问天、我的复盘五个移动入口；底部导航固定，
+  页面均可完整纵向滚动且没有文档级横向溢出。
+- 观势、观气、观心三页均复核；观气滚动到底后“个人合参”和“五行对应行业”可达。
+- 同账号、同数据库快照、同主题和同视口下，原版与迁移版问天布局和计算样式一致。
+
+机器可读记录见`browser-acceptance.json`。截图和更广的桌面/移动基线继续沿用切片10证据目录。
+
+## 4. 数据与部署边界
+
+- API/数据库比较使用两个隔离副本：`slice11-final-original`与`slice11-final-migrated`。
+- 没有写入根目录正式`data/review.db`，没有修改`.env`或私有Skill。
+- 没有占用`8765`，没有执行Docker构建、NAS测试或服务器切换。
+- 原版根目录仍是正式运行基线；`app/`只是等待人工验收的候选。
+- `next/`保持冻结，没有作为代码、样式、测试或文档来源。
+
+## 5. 回档与最终确认
+
+切片11提交和标签只代表“候选可验收”，不代表删除已被永久确认。人工验收前可按
+`uncertain-code-audit.md`从切片10标签单独恢复任一候选；不需要回退其他已通过迁移切片。
+
+用户人工确认后才允许：
+
+1. 把试删候选状态改为“确认废弃”。
+2. 建立最终完成标签。
+3. 决定本地或Docker正式切换时间。
+4. 另行制定根目录兼容外壳和旧实现的清理计划。
+
+人工维护、验证、切换和回退步骤见`docs/migration/人工维护与本地切换指南.md`。

+# 切片 11：不确定代码审计日志
+
+> 审计基线：`dec3cd12365df5e7d4c391369f14c457cf56d7d9`
+> 恢复标签：`xiaobai-preservation-slice-10-20260731`
+> 原则：只有静态引用、动态注册、运行路径和兼容责任同时排除后才试删；其余继续保留
+> 当前状态：试删后的自动、API、数据库和浏览器验收已通过，等待用户人工确认
+
+本日志记录试删前的原位置、内容指纹、证据、决定和恢复方式。试删不等于永久废弃；自动回归通过后仍需用户在迁移版真实页面完成人工验收，才能把删除结论视为最终确认。
+
+## 1. `app/demo_data.py`
+
+- 类型：旧演示行情构造器，376行、17,199字节。
+- SHA-256：`fb69682d499993534e7ee029989b35cf512c455eec49e07d7b09658cddd9e028`。
+- 静态引用：运行代码、配置、启动入口、Docker、页面及后台任务均没有导入或调用`DEMO_LIMITS`、`build_demo_dashboard`、`build_demo_dragon_tiger`或`build_demo_stock_detail`。
+- 动态/注册路径：没有模块名字符串、插件注册或反射加载。
+- 产品事实：`app/README.md`明确主行情不再回退演示数据；行情服务和Repository只负责排除历史`source=demo`缓存，未依赖本文件。
+- 兼容责任：不参与数据库schema、历史记录解释或配置读取。
+- 决定：进入试删。
+- 恢复：从切片10标签恢复`app/demo_data.py`。
+
+## 2. `app/frontend/heaven-loading.js`
+
+- 类型：旧版问天加载动画，642行、30,563字节。
+- SHA-256：`ee914762b893a89f745e9e705cac6840c1dbd6c5b68dc7a47620b8c4db3615c7`。
+- 静态引用：`app/frontend/index.html`只加载`/pages/heaven/loading-v2.js`，没有加载本文件。
+- 动态/注册路径：没有脚本清单、页面注册表或运行时代码引用旧路径；新旧文件虽然都导出`window.HeavenLoadingCanvas`，但浏览器只能执行v2。
+- 运行证据：切片10已覆盖观势、观气和观心解读加载动画，v2节点、动画名及可见行为与原版基线一致。
+- 兼容责任：不是数据库、配置或历史数据资产。
+- 决定：进入试删。
+- 恢复：从切片10标签恢复该文件。
+
+## 3. 五个疑似无引用前端函数
+
+全前端非供应商JavaScript逐词扫描后，下列符号都只有定义本身一次；HTML、页面注册表、事件绑定、字符串查找、测试入口和其他脚本均无消费者：
+
+| 函数 | 位置 | 原用途线索 | 决定 |
+|---|---|---|---|
+| `commonReviewColumns` | `frontend/shared/export.js` | 旧通用导出列定义；当前每个导出入口均显式传列 | 试删 |
+| `outcomeClass` | `frontend/app.js` | 旧昨日涨停结果样式映射；当前渲染不调用 | 试删 |
+| `screenerResultMatchesSelection` | `frontend/pages/screener/page.js` | 旧选股结果存在性包装；已由`activeScreenerResultEntry`直接承担 | 试删 |
+| `selectRegime` | `frontend/pages/screener/page.js` | 旧阶段手动切换；当前阶段由盘后数据写入且无按钮绑定 | 试删 |
+| `showHeartRitualCurtain` | `frontend/pages/heaven/page.js` | 旧观心幕帘过场；当前流程直接调用`activateHeartRises` | 试删 |
+
+本次只删除这5个函数，不连带删除`selectedRegime`、`heartRitualCurtain`隐藏节点、`heartCurtainTimer`或相关CSS。后者与仍在使用的选股状态、观心节点和复合选择器相邻，尚不足以证明可独立删除，默认保留。
+
+恢复：从切片10标签按上述文件恢复对应函数；源码映射可通过`docs/migration/evidence/slice-10/frontend-source-map.json`定位。
+
+## 4. `wencai_saved_queries`及其方法
+
+- 类型：历史兼容数据表及用户隔离Repository方法。
+- 当前入口：问财前端和`/api/wencai*`已按用户决定取消；iFinD的`wencai()`能力仍由股池原因补全使用，但不依赖保存查询表。
+- 保留责任：数据库初始化仍创建表和用户索引；`list_wencai_saved_queries`、`save_wencai_query`、`delete_wencai_saved_query`保持已有数据可读取；`test_ifind_features`明确验证跨用户隔离。
+- 风险：当前数据库表为空不能证明所有用户历史库均为空；删除会改变62项schema契约并破坏旧库兼容。
+- 决定：保留，不试删。只有未来正式数据库迁移、导出/归档和用户批准同时具备时才允许移除。
+
+## 5. 试删验收门槛
+
+每次试删后必须同时满足：
+
+1. 全前端符号与资源引用扫描没有悬空消费者。
+2. 全部JavaScript通过`node --check`。
+3. 原版231项测试继续通过，迁移版全量测试通过。
+4. 21个固定只读API与数据库schema/关键表差分继续一致；明确批准删除的运行外文件不应改变API或数据库。
+5. 45项Playwright通过，问天加载动画与智能选股流程无回归。
+6. 用户使用迁移版完成最终人工页面验收。
+
+任一项失败时，按本日志指向的切片10标签恢复对应候选，不把其他已通过候选一起回退。
+
+## 6. 试删后结果
+
+- 五个前端符号在全部非供应商JavaScript中的剩余引用均为0。
+- 运行代码中没有`demo_data`导入；页面只请求`/pages/heaven/loading-v2.js`。
+- 24个现存前端JavaScript文件通过`node --check`。
+- 原版231项、迁移版298项Python测试和45项Playwright全部通过。
+- 21个只读API、62个schema对象和21张关键表继续与原版一致。
+- 桌面日间/夜间及390x844移动端真实页面检查通过，问天三页和观气底部内容可达。
+- `wencai_saved_queries`及三个方法保持存在，并由清理契约测试持续保护。
+
+因此上述删除保持“候选试删”状态；只有用户人工验收后才改为“确认废弃”。
