+## 2026-10-16 — 生时校正的交付范围按还活着的时间段显示
+
+问完题之后，卡片和旁白不再把中间已经排除的空档算进「目前范围」。相邻不超过 4 分钟的段会并在一起；超过三段时只写出前三段，并写明一共几段、大约还剩多少分钟。打分、采用和确认没有改。

 ## 2026-10-16 — 大运接口不再编造周期，Ashtottari 计入出生余额
 
 - 选择一套还没接上引擎的大运时，接口会明确回复未实现，不再返回编出来的周期。已经接上的大运与完整解读使用同一套算法。Vimshottari 的算法和返回字段不变。

+## BUG-1367 | 交付范围按声明窗口的首尾显示，中间空档也被算进去
+
+- 状态：resolved
+- 首次发现 / 最近更新：2026-10-16 / 2026-10-16
+- 来源：issue #77。任务书 `docs/tasks/TASK-rectification-narrower-delivery-20261016.md`。研究记录里 ±60 的显示宽度中位约 71 分钟、实际剩余中位约 42 分钟。那份 77 例回放本轮没有重跑。
+- 现象：问完题后，交付卡上的「目前范围」是一整段首尾。中间已经排除的空档仍看起来像还可能的时间。
+- 触发条件：同一声明窗口里有多段还活着的簇，段与段之间的空档大于 4 分钟。`segment_index` 是用户声明的窗口段，不是候选簇。
+- 根因：`interval_union_width` 和 `unionWindowIntervals` 把同一声明段里的区间收成最早到最晚。交付卡标题走这条包络。
+- 修复：卡片、旁白、口头可说的钟点和遥测宽度改用还活着的簇。落后峰值达到 8 分的候选不进这段显示，和现在的进区间门槛相同。相邻空档不超过 4 分钟的段合并；超过三段时只写前三段，并写一共几段、大约还剩多少分钟。打分、采用、确认、分离和 `MIN_SEPARATION_LEAD` 不动。写盘和读盘仍用同一个 8。会话标题仍由数据库里的单段生成，本轮不改表。
+- 验证：`frontend/tests/rectification-living-display-20261016.test.ts` 覆盖单段、空档 4 分钟合并、空档 5 分钟拆开、五段只显示前三段，以及卡片标题不再画出整段包络。`tests/test_rectification_living_display_intervals.py` 锁定同一套合并，并断言同一对区间的决策包络宽度不变。
+- 防复发：上述测试。显示函数放在密封打分文件之外，打分路径不引用它。没有簇区间的旧结果仍用原来的首尾。

+
+- 状态：blocked
+- 首次发现 / 最近更新：2026-10-16 / 2026-10-16
+- 来源：issue #77 任务书根因 2。本轮没有新的回放来复核「同侧占比」。
+- 现象：后面几题往往排除得很少。可出题数量和轮数上限都停在 8 这一档。
+- 触发条件：探针仍按原有顺序供给；`DEFAULT_MAX_DISCRIMINATION_ROUNDS = 8`。
+- 根因：任务书指向探针供给上限和选题不按剩余后验对半。本轮没有改这些文件，也没有用新回放重新测量，根因沿用任务书。
+- 修复：未改。探针文件在密封打分身份里。对半出题会改变问哪些题，必须先有红线里的真值保留对照。本轮没有跑成 77 例、三个窗口、全对以及分别翻转第 1、3、5 题的生产回放，所以这项撤下。红线没有放宽。
+- 验证：轮数上限仍是 8。没有新增选题测试。
+- 防复发：在这项真正交付之前，不得把「少数一侧不足两成仍不出题」写成已经生效。

+
+- 状态：blocked
+- 首次发现 / 最近更新：2026-10-16 / 2026-10-16
+- 来源：issue #77 任务书根因 3。本轮没有分档回放。
+- 现象：一道题通常只拉开约 4 分。候选至少要连续两道题都反向，才会离开交付区间。
+- 触发条件：`credible_range`、`credible_intervals` 和还有效的候选都用 `MIN_SEPARATION_LEAD = 8`。
+- 根因：任务书写明进区间门槛是 8，而单题分差更小。本轮没有把门槛改成 6，也没有新回放证明改成 6 之后真值仍留在区间里。
+- 修复：未新增另一套交付门槛，也没有按窗口回退表。写盘和读盘仍都用 8，避免一边 6、一边 8。分离、采用、确认和盘型段汇总仍用 8。
+- 验证：`MIN_SEPARATION_LEAD` 仍是 8。没有「写 6 读 6」的新测试，因为这条路径没有落地。
+- 防复发：不得只改写盘或只改读盘。不得用修改 `MIN_SEPARATION_LEAD` 来收窄区间。
+- 相关记录：BUG-423、BUG-560、BUG-1367。
+- 复发自：无。
+- 修复版本：未修。

+# 进度：生时校正交付区间收窄 2026-10-16
+
+issue #77。分支 `codex/rectification-narrower-delivery-20261016`。
+
+## 结论
+
+这一轮只交付分段显示（T1）。问完题之后，卡片和旁白按还活着的时间段写「目前范围」，不再把中间已经排除的空档涂成一整段。打分、采用、确认、出题和进区间门槛都没有改。
+
+T0 基线回放没有跑。T2 对半出题、T3 门槛 6、T4 合并回放都没有做。原因：任务书的红线要求先在同一套生产回放上量出「真值还在不在交付区间」。现有回放脚本不记录这一格，也不翻转第 1、3、5 题。没有这组数字就不能改「谁留在区间里」或「问哪一题」。红线没有放宽。
+
+## 基线
+
+- 计划里的 base `712a0fd2a19947405a1dfb486bad96a7661d41c3` 在 `git fetch origin --prune` 之后存在，分支从这里开出。
+- 任务书示例里的 `origin/staging` @ `9b7509155` 不是这次开工点。fetch 时 `origin/staging` 已经是 `712a0fd2a19947405a1dfb486bad96a7661d41c3`。
+- 研究记录 `docs/research/rectification_width_funnel_2026_10_16.md` 只作背景，不用它代替本轮基线。
+
+## 做了什么
+
+- 前端 `livingDisplayFromCandidates`：还没淘汰、并且离峰值不足 8 分的候选，取出各自的簇区间。空档不超过 4 分钟的相邻段合并；空档 5 分钟保持两段。宽度按每段首尾都算进去的分钟数相加。超过 3 段时，`windowIntervalsLabel` 只写前 3 段，再写「等 N 段，共约 X 分钟」。
+- 没有簇区间的旧结果仍用原来的首尾，避免把缺字段收成空白。
+- 交付卡标题、盘型交付的分钟范围、采用和中间轮旁白、口头可说的钟点、遥测里的范围宽度，在有簇区间时改用上面的结果。
+- Python 侧同一套合并放在 `scripts/rectification/living_display_intervals.py`。没有放进 `candidate_window.py`，因为那个文件在密封打分身份里，改它会改冻结哈希。打分代码不引用这个新文件。
+- `frontend/DESIGN.md`、`frontend/docs/VOICE.md`、`CHANGELOG.md` 已同步。
+
+## 口径
+
+| 位置 | 这一轮用的口径 |
+| --- | --- |
+| `scripts/rectification/candidate_window.py` 的 `interval_union_width` | 决策包络，未改 |
+| `scripts/rectification/api_service.py` 的宽度 | 决策包络，未改 |
+| `scripts/rectification/decision_policy.py` 的平台宽度 | 决策包络，未改 |
+| `credible-range.ts` 的还有效区间 | 决策包络，门槛仍是 8 |
+| `windowIntervalsWidth`、精度门、候选平台 | 决策包络，未改 |
+| 技能报告里的「不可分宽度」 | 决策包络，未改 |
+| 时间轴色带 | 仍是 `credible_range` 的单段首尾 |
+| 会话标题 | 仍是数据库函数里的单段。本轮不改表 |
+| 扫描块上的钟点标签 | 仍用块自己的区间；段数超过 3 时会走同一句「等 N 段」 |
+| 交付卡、盘型范围、旁白、口头钟点、遥测宽度 | 有簇区间时用还活着的段；没有则仍用旧首尾 |
+
+只读范围那一行要等结果里已经有 `credible_range` 才出现。簇完全拆开、旧范围为空时，这行仍不显示；卡片标题仍按活着的段写。
+
+## 没做的
+
+- T0：没有产出 `docs/research/rectification_narrower_delivery_baseline_2026_10_16.json`。
+- T2：`DEFAULT_MAX_DISCRIMINATION_ROUNDS` 仍是 8。探针供给、对半选题、少数一侧不足 20% 就不出，都没改。记为 BUG-1368，状态 blocked。
+- T3：没有 `DELIVERY_RANGE_LEAD`，没有分档回退表。写盘和读盘仍都是 8。记为 BUG-1369，状态 blocked。
+- T4：没有产出 `docs/research/rectification_narrower_delivery_replay_2026_10_16.json`。
+- 显示用的候选是虚构的卡片形状，不是一份 ±60 黄金样本。仓库里现成的黄金样本没有「前后 60 分钟、中间有大于 4 分钟空档」的簇，本轮也没有跑出这样一份回放。
+- 真机清单写在 `docs/testing/rectification-narrower-delivery-20261016.md`，没有在手机或浏览器里走一遍。

+## 检查
+
+| 检查 | 命令 | 结果数字 |
+| --- | --- | --- |
+| 类型检查 | `frontend` 下 `tsc --noEmit` | 0 错误 |
+| lint | `frontend` 下 `npm run lint` | 0 error，123 warning（原有警告，没有顺手改） |
+| 显示单测 | 含在下面的前端测试里 | 6 条都通过 |
+| Python 显示 | `.venv\Scripts\python.exe -m pytest tests/test_rectification_living_display_intervals.py -q` | 4 passed |
+| 隐私标记 | `.venv\Scripts\python.exe -m pytest tests/test_repo_privacy_markers.py -q` | 62 passed |
+| 前端测试 | 564 个不含数据库夹具的测试文件，`tsx --test --test-concurrency=8` | TAP 计 3938 条：通过 3893，失败 45，退出码 1 |
+| 生产路径 PG 回放 | `varga_resolution_persisted_replay.py`，77 例 × 三档 × {全对，翻第 1/3/5 题} | 未跑 |
+| Python 快速门 | `run_quality_gate.py --profile quick` | 未跑 |
+| 数据库套件 | `npm run test:db` | 未跑（没改表） |
+| 首屏构建 | `frontend` 下 `npm run build` | 退出码 0。`/` 为 Static。首页引用的 29 个 JS 按 gzip-9 合计 570406 字节。没有用改动前的代码在这台机器上再构建一次，所以不写增减百分比 |
+
+现有回放脚本固定全答对、最多 6 轮、两种段顺序都跑，记录的是分盘段是否保住真值，不是「真值在不在交付区间」。一次中途编译失败的单例冒烟不能当作基线，已经作废。
+
+`npm test` 先按全量启动。数据库容器的健康检查一直停在 starting，C 盘当时只剩约 4.2 GB，所以中止了这次全量，并清掉测试容器。随后改跑 564 个不启动数据库夹具的测试文件，跳过 50 个会拉起 PostgreSQL 的文件。45 条失败都不是这次显示改动的断言：4 条是 Windows 上把盘符拼成 `G:\G:\` 后找不到文件；6 条是本机没有 WSL；约 32 条是加载 `tailwind-merge` 时解析失败。其中首页往返那一个文件单独再跑仍是 17 失败、0 通过，同一条解析错误，不是并行才出现；1 条是回答计时期望 `answer_truncated` 实际得到 `empty_answer`；2 条是技能路径用反斜杠，对不上写成正斜杠的断言。本轮 6 条分段显示测试都在通过的 3893 条里。日志没有打出运行器最后的汇总行，上面的数字是按 TAP 的 ok / not ok 行数出来的。
+
+## 偏离
+
+- 任务书让步是先交 T0+T1。T0 没有数字，所以不能声称 ±60 已从约 71 分钟降到约 42 分钟。代码只保证：有空档时卡片不再画包络。
+- 会话标题和「不可分宽度」仍是决策包络。标题要改数据库函数，任务书禁止本轮改表。
+- 显示成员仍用门槛 8，因为门槛 6 没有交付。这和写盘、读盘保持同一个数。

+# 真机清单：交付范围按还活着的段显示（2026-10-16）
+
+这一版只改「目前范围」怎么写。题数仍是原来的上限，进区间的门槛仍是 8 分。不要把任何人的出生日期、钟点或姓名写进这份清单、进度或聊天记录。
+
+在一台已登录的测试账号上，用前后各 30 分钟的窗口走完一次校正：
+
+1. 问完这一轮会出的选择题，直到出现范围卡片。
+2. 看卡片标题是一段，还是用顿号分开的几段。
+3. 若是两段或三段，旁白里应能看到「剩余约 X 分钟，分 N 段」。不应出现「定到分钟」。
+4. 若超过三段，标题只写最前面的三段，并写一共几段、大约还剩多少分钟。
+5. 中间已经空出来的间隔，不应再被画成一整段连续时间。
+6. 点「更像这个」之后，排盘用的是选中的那一分钟，不是把整段都确认掉。
+7. 这一版不会因为门槛改成 6 而少留人，也不会多问到 12 题。若题数或收窄幅度和改版前一样，这是预期。
+
+本轮没有在真机上执行这份清单。
