+## BUG-976 | 普通对话寒暄被当作咨询：全量排盘、长判词与扣点
+
+- 状态：blocked（独立审查、Linux 全量 3566/3566、标准 DB 40/40 及构建/gzip 通过；staging 部署与真人实测待闭环）
+- 首次发现 / 最近更新：2026-09-20。
+- 影响面：普通 `POST /api/consult` 三种模式、流式 UI、咨询账务与历史恢复。
+- 现象与触发：纯打招呼也进入强制计算与报告形状，并扣一次咨询点数。
+- 根因：入口没有非咨询轮，预留与完整咨询链覆盖全部普通消息；原取消函数只退款不持久化回复，没有免费完成语义。
+- 修复：所选模型一次短结构化分类并写寒暄回复，3 秒 fail-open，无 Skill/工具/出生资料注入；只看本轮问题、称呼与最后完整可见问答。普通入口命中后先原子免费结算，再发 answer.delta + 无 receipt 的完成事件。新 service_role-only RPC 沿用 advisory lock，校验所属/状态/回复，记录真实 usage、按 credit_amount 退款，完成请求并释放 reservation。完成重试不退款，已收费咨询不能借此退款。UI 标记持久化，寒暄不造步骤/思考/技法。
+- 验证：假模型、schema、超时、断连、流协议和 SSR 展示定向通过；真实 PostgreSQL 17 覆盖退款幂等、回复冲突、跨用户/会话、取消竞态、已收费拒退、真实成本、事务回滚和无点数来源。Linux tsc 0、lint 0 error/120 既有 warnings；标准 DB 基线 39/39、候选 40/40，完整构建两侧首页 Static，首屏 JS gzip 621,299 → 621,605 B（+0.0493%）。Windows 迁移镜像与 Skill alias EPERM 的历史不删除，Linux 完整全量及部署证据见进度。
+- 防复发：保留分类失败回咨询、服务端专有授权、先持久化后完成、刷新标记、取消/完成共享锁回归；不得加入寒暄关键词/正则/字数分类。独立审查补获 SDK strict 校验日志可能携带原文、且非法输出丢 usage 两项，已局部静默 SDK logger 并保留生成结果后严格解析，真实 SDK 假模型回归断言隐私、fail-open 与成本保留；相关定向主会话复跑 59/59，真实库定向复跑 1/1。
+- 关联记录：BUG-922 / BUG-923 / BUG-937 / BUG-938；这是非咨询轮的新边界，不是旧每轮排盘防线复发。every turn、prepareStep、contractReady 与两处 requireTool:true 未改。BUG-280/305 的空回答或失败不得结算语义保持；BUG-347 的真实咨询思考历史不删除。
+- 边界：reserve 仍在分类前，零点无订阅仍被拦；超时未知 usage 不伪称零，晚 usage 只观测不追写完成账本。
+- 修复版本：`539d4dae`，已合入 staging 并部署（`/api/health` 的 `deployment.gitCommit` 与 `apiGitCommit` 均为该 SHA，`latestMigration` = `20260920010000_consultation_free_completion.sql`，2026-09-20 由 Claude 独立核对）；详见 PROGRESS-consult-smalltalk-fastpath-20260920。状态保持 blocked：真人三模式与余额走查未做。

+- 状态：blocked（本地合同通过；真实三模式模型验收待执行）
+- 首次发现 / 最近更新：2026-09-20。
+- 影响面：productConversationVoice、natalSpokenReportContract，窗口/无出生分钟的简短社交回复。
+- 现象与触发：只打招呼也套开场形状；窗口与一般模式拿不到原本命 chit-chat 豁免句。
+- 根因：豁免写在仅本命拼接的常量内，共享 voice 的四步形状没有例外。
+- 修复：将豁免移到三模式共享 voice，明确只回一句、≤20 字、无句号、无星盘主张；本命领域问题仍需原 opener-plus-skeleton。主修仍是 BUG-976 分流，提示词不代替计费与计算边界。
+- 验证：三种指令模板展开共享 voice 后均含豁免，原 OPENER SHAPE 合同保留；未用真实模型假装语义验收。
+- 防复发：共享语气规则不能只放单一模式专属合同；混合咨询/解释/纠错/抱怨仍走完整路径。
+- 关联记录：BUG-922 / BUG-923 的边界之外，不撤销每轮咨询排盘；与 BUG-976 配套。
+- 修复版本：`539d4dae`，已合入 staging 并部署，Skill 版本不变。状态保持 blocked：真实模型三模式语义验收未做。

+
+| 范围 | 实现 |
+| --- | --- |

+| 路由 | resolveConsultationQuestion 与预留/问题落盘之后、主 Agent/标题/摘要之前分流；仅 entrypoint undefined；三个特殊入口保持原链（旧校正入口仍拒绝）；寒暄不启动标题/摘要模型 |
+| 流 | 沿用实际 application/x-ndjson，不另造 SSE 协议；先成功持久化/退款再 answer.delta + run.completed(responseKind=smalltalk)，无 activity/receipt；失败只 run.failed，不能声称成功；断连不打断服务端结算 |
+| SQL | 仅新增 complete_consultation_free 函数，无表变更；沿用 advisory lock/owner/session/status 校验；complete_usage 写真实成本；按 reservation.credit_amount 退款并记交易；request completed、reservation released，释放订阅 quota；同回复重试成功不退款，不同回复冲突、取消拒绝、收费完成不可退 |
+| 权限 | 仅 service_role grant，无 admin_runtime 新 grant，撤销 PUBLIC/anon/authenticated；服务端 createAdminSupabaseClient 使用 service role，客户端 RPC 是 authenticated，responseKind 自报不产生免费权力 |
+| UI | responseKind 从流/header→hook→StreamingReply/ChatMessage→transcript/row→cloud read 贯穿，刷新不重建虚构步骤；寒暄隐藏思考/活动/技法；未有真实活动时不造分类思考；Home 只新增一行 prop，0 新 useState/useRef |
+| 语气 | 豁免移到共享 productConversationVoice，三模式均含；领域咨询原开场骨架不改，Skill 版本不变 |
+| 观测 | classifier 独立封闭机器码、耗时/tokens/按模型价格估算 cost；成功咨询账本合并分类 usage，寒暄记其真实 usage；缓存 normalized usage 合并不丢失；无问题/姓名/出生资料/输出原文日志 |
+
+## 保持的安全合同与产品边界
+
+- BUG-922/923/937/938 及相关历史已检索阅读；最大号 975，本轮新增 976/977。没有修改 index.ts every turn 两句、consultationNatalPrepareStep/WindowPrepareStep、contractReady 或原 stream-agent-response；两处 requireTool:true 保持。
+- **预留仍在分类前**。零余额无有效订阅用户仍受前端守卫/服务端 402 限制；没有擅自改计费入口为匿名无限免费模型代理。profile/mode/session 校验也保持。
+- 历史可见正文可能含此前解读，任务允许这一对历史；只作为用户语义数据，不是工具/系统星盘证据，提示词禁止复述盘上主张。未声称能力剥夺可数学保证模型零幻觉。
+- 订阅无 credit debit 时不加点；reservation released 不再计入 reserved/completed quota，ledger 仍有实际成本。定向覆盖无点数来源分支；真实订阅授权链见真人清单。
+- 供应商忽略 abort 时最多等待约 3 秒；晚 usage 用 late_usage 观测，不追写已完成/释放 reservation，避免改变状态和重复账务。供应商错误/超时未返回 usage 为 unknown，不伪报真实零成本；价格字段计算是既有模型价格估算，不是供应商账单对账。
+- 误判成本按任务书：咨询误判成寒暄会收到一句短回应，需要再问一次；产品接受它比整轮合同失败轻。漏判仍按原咨询处理，宁可多算一次，不用关键词/正则/长度补分类。假模型测试只证明传输/路由/严格解析，不证明真实语义准确率或延迟 P50。

+
+## 主会话独立审查与最终证据
+
+- SQL、RPC 角色、迁移打包/加载静态复核未发现确认缺陷；真实数据库独立回归通过，不等于标准整套 DB 通过。
+- 修复审查发现：Mastra 默认 strict 校验会把非法模型输出附入 SDK 日志，同时在读取 usage 前抛错。现对独立分类 Agent 与结构化输出处理器使用 `noopLogger`，结构化生成采用保留结果的 `errorStrategy: warn`；外层原有 strict schema 仍是唯一接纳门。真实 SDK 内存假模型覆盖合法输出、非法 schema、坏 JSON、供应商异常；验证一次调用、无工具、96 token cap、原文不进 console/stdout/stderr、非法输出仍保留 23/7 tokens。
+- 最终证据：`review-final-targeted.log`（59/59）、`review-final-full-concurrency2.log`（3522/3444/78）、`review-final-failure-comparison.json`（全量与 DB 逐项名单）、`review-final-tsc.log`（0）、`review-final-lint.log`（0 error/120 warnings）、`review-final-db-targeted.log`（1/1）、`review-final-build.log`（EPERM）。
+- 原默认并发多次出现内存分配失败，导致部分测试未完整收集；这些失败日志保留，不用作最终测试总数。中途构建还出现 `.next` rmdir UNKNOWN；最终单独复跑重新到达编译成功后 Skill symlink EPERM。未改业务、断言或依赖去迎合环境。
+- 执行与审查子代理最后因服务端 API 403 insufficient balance 中断；主会话接手完成上述复验与记录，未将中断代理的待完成工作冒充结果。
+- 本轮执行期间远端引用前进至 `5049e784`，相对基线仅新增另一份任务书及索引。未在脏工作树拉取；未来提交/推送前必须重新 fetch、核对 BUG 编号和整合任务索引，不能直接覆盖他人文档。
+
+## Linux 隔离补验（用户授权继续，2026-09-20）
+
+- 主机 Docker Desktop：4 CPU / 8 GB；使用本轮专属 runner、DinD 和 named volume，不挂宿主 Docker socket，不访问其他会话容器或凭据。Node `22-bookworm`（拉取 digest `sha256:dd5847a04b0deee391fa145f1f4c6d214196668b6bcc7988ebed67249f226844`），容器内按未修改的 package-lock 执行 `npm ci`；两侧依赖副本相同，不复用 Windows node_modules。
+- 基线从根目录 `git archive fcad06372`；候选为相同 archive + 33 个本轮变更文件。8 个 Git symlink 均保真，overlay 全部逐字节匹配工作树，输入哈希清单 `artifacts/smalltalk/linux-input-manifest.json`。为 Git 文件跟踪合同建立仅容器内使用的临时 Git 快照，非发布提交。
+- runner 与专属 DinD 共享网络命名空间和 `/work` volume；`DOCKER_HOST` 仅 loopback，无发布端口，`TMPDIR=/work/tmp`，fixture 上限 1；真实 PostgreSQL 17、标准双迁移目录，无 MIGRATIONS_DIRECTORY 绕行。

+| 首页 JS gzip | 621,299 B / 25 文件 | 621,605 B / 25 文件 | +306 B / +0.0493%，在 ±2% 内 |
+
+- gzip 口径：各自全新 `.next` 的 `.next/server/app/index.html` 中去重 `/_next/static/**.js` 引用，每文件 gzip level 9 后求和；不混入其他路由、旧 hash chunk 或 CSS。复算脚本与逐文件清单在本地 artifacts，不整目录提交。
+- 日志：`artifacts/smalltalk/linux-logs/{base,proposed}-{tsc,lint,test,db,build}.log` 与 `*-gzip.json`。脚本末尾退出 0 不能代表全部测试成功，逐项结果按表中原始日志记录。
+- Gitea REST Actions API 未认证为 401；公开 `/root/Jyotisha/actions` 网页可读，可在不读取凭据的前提下核对门禁。推送前 staging health 为 `12fdaed90b81014378fe5eaa9231e50d2b838a37`，不是本轮部署证据。
+- 远端期间另有校正研究提交 `932f2fff`（BUG-978～980），本轮编号无冲突。提交后只整合本分支，保留双方共享文档；不操作他人工作树、不 stash、不提升 main。
+
+## 剩余未做 / 交接
+
+1. 独立代码审查与 Linux 平台验收已完成；最终日志 `linux-logs/{base,proposed}-test-final.log`，机器对照 `final-test-comparison.json`。隐私扫描 `commercial_privacy_artifact_scan.py --json` 为 pass、0 finding（3188 文件）。
+2. 提交后整合最新 `origin/staging`、快进推送、核对远端 SHA 与 Gitea 门禁/自动迁移/部署。远端至 `03cba478` 额外两提交仅跨午夜任务书与索引，需保留并行工作。

+# TASK · 跨午夜修复 review 修复单：门禁级浮点哈希断言（2026-09-20）
+
+> 状态：待领取。**这是 `aa46da10` 的合入阻塞项**：核心修复本身已验收通过，卡住的是随它新增的一条测试会让快速门在别的机器上红。
+> 本单只改测试断言方式，**不改被修的打分代码**。
+
+## 0. 基线与交付
+
+- 基线：分支 `codex/rectification-cross-midnight-20260920` = `aa46da10`（不是 `staging`；本单改的是该分支上的新增测试）。
+- 参照：`origin/staging` 在 review 时为 `f8e40e5d`；`aa46da10` 的分叉点是 `03cba478`。
+- worktree `.worktrees/rectification-cross-midnight-gate-fix-20260920`，分支从 `aa46da10` 起，或直接在原分支上追加提交。
+- **合入顺序**：本单修完 → `aa46da10` 方可快进推 `staging` → 之后才做 `TASK-rectification-cross-midnight-dasha-fix-20260920.md`（BUG-984 缓存身份补单）。三者串行，不得并行改同一批测试文件。
+
+## 1. 事故实证
+
+Claude 2026-09-20 在 `aa46da10` 上独立 review，以下全部为实测。
+
+### 1.1 断言写法
+
+`tests/test_dasha_transition_proximity_cross_midnight.py` 的 `test_same_day_public_aa_scores_keep_pre_fix_bytes` 用 `hashlib.sha256(_canonical(scores)).hexdigest()` 把 121 个分数的 canonical JSON 哈希**写死成字面量**，三个 ordinal 各一个。
+
+### 1.2 实测：该测试在别的机器上红，且与修复无关
+
+| 运行环境 | 结果 |
+| --- | --- |
+| `aa46da10`（修复分支），Claude 本机 | `ordinal 2`、`ordinal 3` **红** |
+| `03cba478`（修复前基线），把同一测试文件拷过去跑 | `ordinal 2`、`ordinal 3` **同样红** |
+
+两侧红的是同一组，**说明不是本轮修复造成的**，是跨机浮点差异。
+
+进一步用同机对照确认修复无辜：以该测试自己的 `shifted_window(case, 0, 60)` 口径，在基线与修复分支各算一次 121 个分数——
+
+| ordinal | 基线哈希前 16 位 | 修复分支哈希前 16 位 | 是否相同 |
+| --- | --- | --- | --- |
+| 1 | `5e47d5b17c9534f1` | `5e47d5b17c9534f1` | 是 |
+| 2 | `b371f6430c7adfc8` | `b371f6430c7adfc8` | 是 |
+| 3 | `3fb2b626d86eb7c3` | `3fb2b626d86eb7c3` | 是 |
+
+**同日分数在基线与修复之间逐位不变**（另经半径 10 的 6 例独立复核，同样 6/6 相同；执行方自己的 `docs/testing/rectification-cross-midnight-scoring-evidence-20260920.json` 覆盖 19 例 / 2299 候选，全部 `scores_bytes_equal: true`）。红的原因只是本机算出的字节与写死的字面量不同。
+
+### 1.3 影响面：它在快速门里
+
+`tests/test_rectification_cross_midnight_gate.py` 把该用例 re-export，文件名命中 `scripts/run_quality_gate.py` 的 `CORE_PYTEST_TARGETS` 中的 `tests/test_rectification_*.py`。实测同 glob：
+
+| 分支 | 结果 |
+| --- | --- |
+| `03cba478` | **214 passed / 0 failed** |
+| `aa46da10` | **4 failed**（2 条 × 2，bridge 重复收集） |
+
+即：推 `staging` 会触发 `backend-quality-gate`，而该门在浮点行为与执行方机器不一致的任何机器上都会红。
+
+### 1.4 差异不是 repr 噪声，是第 4 位真的不同
+
+实测该组 121 个分数全部满足 `repr(s) == repr(round(s, 4))`，**0 个带浮点尾噪**。所以哈希不同意味着至少一个分数在第 4 位小数上真的不同，属跨机 libm / pyswisseph 层面的差异，不是 JSON 序列化噪声。这类差异无法靠「多取几位」或「统一序列化」消除。
+
+### 1.5 同一提交里引用了这条教训，又踩了它
+
+`tests/test_rectification_engine_memoization.py` 的 docstring（本轮刚被同一提交修改过）明写：跨机 libm / pyswisseph 舍入**已经**让 `margin_percent` 漂移 `1.1e-3`，因此**不得**对整份 payload 做 `==` 比较。写死浮点分数的 SHA-256 比整份 `==` 更严格。
+
+### 1.6 执行方自己的证据文件用的是正确做法
+
+`docs/testing/rectification-cross-midnight-scoring-evidence-20260920.json` 的 `same_day.comparisons` 每条记的是 `scores_bytes_equal` / `matrix_bytes_equal`——**同一台机器上基线与当前的对照**，而不是跨机硬编码哈希。正确做法已经在仓库里，只是没有用在测试断言上。
+
+## 2. 根因
+
+这条回归要证的是「修复不改同日分数」，那是一个**相对**不变量：同机、同环境下，基线行为与当前行为一致。但它被实现成了**绝对**不变量：当前行为等于某一台机器在某一时刻算出的字节。绝对写法把 libm / pyswisseph 的版本差异一并纳入了断言范围，于是换机器就红，而红的信息与要守护的性质无关。
+
+## 3. 决策记录
+
+- **2026-09-20 产品要求就本项出修复单。**
+- 本单只改测试断言方式。`aa46da10` 的核心修复（`dasha_transition_proximity.py` 取候选日期、缓存键带日期、`scoring_service.py` 版本号 7→8）已由 Claude 独立验收通过，**不在本单改动范围**。
+- BUG-984（时段缓存不校验算法身份）另有补单，串行在本单与 `aa46da10` 合入之后。
+
+## 4. 硬红线
+
+1. **不得用消红代替修复**：不得删除该测试、不得 `skip` / `xfail`、不得把哈希改成「本机当前算出的值」——最后一种只是把红转移给下一台机器。
+2. **不得改** `scripts/rectification/dasha_transition_proximity.py` 与 `scripts/rectification/scoring_service.py`。核心修复已验收通过（§1.2）。
+3. 不得动打分常数、确认门、Skill 版本、`INPUT_CONTRACT_VERSION`、已封存的历史哈希。
+4. **不得因为改测试而降低覆盖**：「同日不变性」这条回归必须仍然存在，且仍然留在快速门里。
+5. 处理 bridge 重复收集时，不得让原测试脱离快速门 glob。
+6. 不顺手升级依赖、不修不在本单内的 warning。
+
+## 5. 任务分解
+
+### F1 · 把绝对哈希换成同机相对比对（BUG-985）
+
+**推荐做法**：用生产代码里**已经存在**的 legacy 回退路径造出「修复前行为」，在同一次运行内对照。
+
+`merge_transition_proximity()` 对缺少 `candidate_at` 的上下文仍回退到请求的 `birth_date`（即修复前的行为，该分支本轮已保留并有专门测试 `test_legacy_context_without_candidate_at_retains_request_date` 覆盖）。因此同日窗口下：
+
+- A 组：正常 contexts（带 `candidate_at`，走新路径）
+- B 组：同一批 contexts 去掉 `candidate_at`（走 legacy 路径 = 修复前行为）
+- 断言 **A 组分数与 B 组分数逐位相等**
+
+这条断言在任何机器上都成立（因为同日窗口下候选日期本就等于 `birth_date`），且直指要守护的性质，不含任何跨机字面量。
+
+**备选做法**（若 A/B 构造受限）：改为结构性断言——同日窗口下，`_vim_start_dates` / `_narayana_start_dates` 收到的日期参数集合恰为 `{birth_date}`。该文件已有同型写法（`test_every_candidate_uses_own_date_and_caches_do_not_cross_dates` 用的就是捕获调用参数）。
+
+验收标准：
+
+- 三个 ordinal 全绿，且**在至少两台浮点环境不同的机器上各跑一次**——执行方自己的机器 + 一台 Linux 全依赖环境；两侧都绿才算通过。做不到两台就在进度记录写成环境缺口，不得写成通过。
+- 把核心修复临时回退（令 `candidate_date` 恒等于 `birth_date`）后，该测试**仍然绿**——证明它守的是同日不变性，不是跨午夜回归的替身；跨午夜回归由 `test_real_cross_midnight_all_candidates_match_independent_dated_calculation` 负责，那条必须仍然在回退后转红。
+- 文件内不再出现任何写死的分数哈希字面量。
+
+### F2 · bridge 重复收集
+
+当前 `tests/test_rectification_cross_midnight_gate.py` 的 re-export 让同一条用例在快速门里被收集两次（实测 4 failed = 2 × 2）。确认这是刻意还是副作用：
+
+- 若刻意（只为让 glob 命中），在文件顶部注释写明「用例会被重复收集，计数非独立用例数」——执行方进度记录里已有「桥接重复收集的 14 项，不能算 14 项独立用例」的说法，把它落到代码注释里。
+- 若非刻意，改为不产生重复计数的挂载方式。
+
+验收标准：快速门里该组的用例数与直接跑原文件一致，或有书面理由写在文件内。
+
+### F3 · 查证 `block_scan` 重算是否经过被修 helper（决定 BUG-984 优先级）
+
+这是 Claude review 的遗留问题，成本低但改变 BUG-984 的定级：
+
+- `frontend/src/lib/rectification-agentic/v9/score-persist.ts` 的 `block_scan` 分支只比 `evidenceLedgerFingerprint` 即返回 `cached:true`，不读 `readV9EngineScoringIdentity()`；`minute` 分支有 `cachedEngineScoreIsReusable` 身份门。
+- `late_night`（`23:00–03:59`，299 分钟）与 `unknown`（1439 分钟）都超过 `MINUTE_GRID_MAX_SPAN_MINUTES = 120`，因此都走 `block_scan`——**而这两类窗口恰恰是最容易跨午夜的**。
+
+要查证的是：`block_scan` 的真实重算路径是否会调用到 `merge_transition_proximity()`。
+
+- **若会**：BUG-981 在 `late_night` / `unknown` 路径上等于没上线，BUG-984 升级为 BUG-981 的阻塞项，必须在宣称跨午夜问题已修之前解决。
+- **若不会**：BUG-984 与本次修复解耦，可按原优先级排。
+
+验收标准：给出调用链证据（从 `block_scan` 分支一路到 `merge_transition_proximity`，或证明不可达），结论写进 `BUG-984` 正文与其补单的 §0。**不得以「大概会」结案。**
+
+### F4 · 记录
+
+- `docs/BUG_HISTORY.md` 新增 `BUG-985`（门禁级浮点哈希断言），关联 `BUG-981`；在「防复发」里写明：**同日/不变性类回归一律用同机相对比对，不得写死跨机浮点字面量**，并引用 `test_rectification_engine_memoization.py` docstring 里已有的同类教训。
+- `BUG-981` 正文补一行：门禁级测试问题已单独立号 `BUG-985`，核心修复本身经独立 review 通过。
+- `BUG-984` 正文补 F3 的结论。
+- `docs/tasks/README.md` 状态板加一行；实现合入 staging 的同一次推送里改状态。
+- `CHANGELOG.md` 不写（纯测试改动，无用户可感知行为变化）。
+
+## 6. 让步顺序
+
+1. **最先保 F1** —— 它是 `aa46da10` 的合入阻塞项，不修则整条跨午夜修复上不了 staging。
+2. 其次 F3 —— 只是查证，成本低，但它决定「跨午夜问题是否真的修好了」这句话能不能说。
+3. F2 可延后，但延后必须在进度记录里写明快速门中该组存在重复计数的事实，不得让后来人把 18 当成 18 条独立用例。
+4. **不得为赶工砍掉 F1 验收里「两台机器各跑一次」那条。** 只在一台机器上绿，正是这次出问题的原因。
+
+## 7. 开工前置命令
+
+```bash
+git fetch origin --prune
+git worktree add -b codex/rectification-cross-midnight-gate-fix-20260920 \
+  .worktrees/rectification-cross-midnight-gate-fix-20260920 \
+  origin/codex/rectification-cross-midnight-20260920
+cd .worktrees/rectification-cross-midnight-gate-fix-20260920
+git log --oneline -1        # 必须是 aa46da10 或其后代
+python3 scripts/pre_work_check.py --remote-timeout 8 --command-timeout 45
+```
+
+复现命令（应在与执行方不同的机器上看到红）：
+
+```bash
+python3 -m pytest tests/test_dasha_transition_proximity_cross_midnight.py -q
+python3 -m pytest tests/test_rectification_*.py -q   # 快速门同 glob
+```
+
+环境备忘：Claude 的 review 环境为 Linux + 系统 `python3` 3.13（可 `import swisseph`），无项目 `.venv`；frontend **无 `node_modules`**，前端侧检查需在有依赖的环境做。执行方环境为 Windows + Python 3.11.7。两者浮点行为不同，正是本单的起因。
+
+## 8. BUG 编号起点
+
+`docs/BUG_HISTORY.md` 在 `origin/staging`（`f8e40e5d`）上的最大号为 **980**；分支 `aa46da10` 已占用 **981–984**（均为 `investigating`，尚未合入 staging）。本单从 **BUG-985** 起。开工时对 `staging` 与本分支两边取最大号再顺延，并在进度记录里写明取的是哪一侧。

 ## 1. Atmosphere & Identity
 
 Jyotisha feels like a private reading room: warm, editorial, grounded, and quiet enough for reflective conversation. The signature is a pale parchment canvas, translucent warm-gray navigation, fine neutral hairlines, and restrained deep-brown accents. Serif display type gives astrological guidance the gravity of a considered essay rather than a generic chatbot.
