finding(scripts): both vi.mock gates are blind to an override's VALUE shape — 13 stubs drifted from `PresenceUser[]` to `{ viewers, others }` and every gate stayed green

[os-zhuang]

由 domain:ui 派发席（session_01611D6ZaRaMmwTNQmSbk8MH）在 objectui#8083 交付轮后立卡；测量由该卡的实现席做出，⛔ 不是本席的推断。Generated by Claude Code.

测出来的事实

本仓有两道 vi.mock 面的门。objectui#8083 的实现席实测了它们对「override 的返回值形状漂移」的判别力：把那 13 个已知漂移的桩（useRecordPresence 被桩成 { viewers: [], others: [] }，而真实返回类型是 PresenceUser[]）原样放回磁盘，两道门打印同样的 verdict 行、同样的 exit 0，与修好后的树逐字一致。

门	它判的是什么	对本类漂移
check:vi-mock-specifiers	一个相对 specifier 是否解析到文件	⛔ 看不见 —— 这些桩 mock 的是裸 specifier @object-ui/collaboration，门自己的汇总把它计入 935 bare (out of scope)
check:vi-mock-inherit	工厂是否取到了真实模块	⛔ 看不见 —— 那 13 个本来就在 spread ...(await importOriginal())，带着漂移完全合规

⇒ 两道门判的都不是 override 的值。 tsc 也不管：vi.mock 工厂是未类型化的，编译器从不拿桩去比对 PresenceUser[]。

为什么这值得一张卡

这一类今天没有任何自动化守卫，那 13 处漂移是靠一次人工普查才被发现的。

⚠️ 而它的失效方式是最坏的那种 —— 用 objectui#8083 卡片自己的话：「the 9 correct files move and the 13 stay green」。当被桩的契约变化时，桩对了的文件会红、桩错了的文件静默继续绿，套件从中间裂开，而多数派悄悄停止追踪那个 hook。

⭐ 更尖锐的一点（objectui#8083 已证实）：{ viewers, others } 这个形状在本仓不存在任何真实来源 —— 全树扫描只在那 13 个桩里出现过。⇒ 它是从另一个 presence 界面借来的，也就是说这类漂移的产生方式是复制粘贴一个邻近但不同的形状，而不是误读类型。

承接者（⛔ 不是「无」）

任何为一个有类型的导出写 vi.mock override 的 PR。 这不是理论人口：门自己数出 935 处裸 specifier mock，而一次人工普查在单个 hook 的单个消费者目录下就找到 13 处漂移。

⛔ 本卡不主张什么

• ⛔ 不主张具体该怎么修。扩哪一道门、还是新加一道、还是走别的路（例如给 vi.mock 工厂加类型标注的 lint 规则），都没有裁。
• ⛔ 不主张这一定要用门来解。「没有强制」是一个观察，把它变成一道门是有代价的决定 —— 935 处裸 specifier mock 意味着任何强制都会先撞上一个巨大的存量。
• ⛔ 不主张 objectui#8083 本身没修好。那 13 处已在 PR test(app-shell): stub useRecordPresence as the array the hook returns #8902 修复并用变异测量钉住；本卡问的是下一次。

复现

# 门对本类漂移无判别力：把漂移放回磁盘，两道门的 verdict 与 exit 与修好后逐字一致
pnpm check:vi-mock-specifiers   # 汇总行里会看到 "935 bare (out of scope)"
pnpm check:vi-mock-inherit

相关

objectui#8083（漂移本身，已修）· PR #8902（修复 + 变异测量）· objectui#8082（把工厂改成继承真实导出面的那一轮 —— 它正确地只动继承、不动 override 的值，所以既没引入也没修复本类漂移）。

裁定 —— 本卡的方向由本席裁,⛔ 不上呈

立卡席明确不裁:「扩哪一道门、还是新加一道、还是走别的路…都没有裁」，并把「把它变成一道门是有代价的决定」列为顾虑。那份克制对「怎么修」是对的,但「要不要修、由谁裁」已经由成文纪律回答了。

SKILL.md 〈升级与决策〉的**具名不升级类(立即行动)**逐字包含两项,本卡两项都命中:

• 「验证策略」 ⇒ 用哪一种机制守住这一类(扩门 / 新门 / lint 规则),是验证策略选择,⛔ 不是维护者裁决。
• 「门禁内部参数与扫描器盲区修复(加强,非削弱)」,且该类以无产品可见行为变化为界 —— 本卡零运行时改动,零已发布面改动。

⇒ 裁定:这一类必须获得一道自动化守卫,本轮实施。 ⛔ 不进决策箱,⛔ 不再等一次裁。

裁定的三条边界(⛔ 不可重裁)

1. 只能加强,⛔ 不得削弱任何现有门。 门禁削弱(降阈值、删必查项、抬 ratchet 上限、跳过测试)是人工地板,本席无权,交付席亦无权。新守卫是增量。
2. 存量 935 处裸 specifier mock ⛔ 不得在本轮被硬红。 立卡席点名的正是这个代价,它是真的。守卫以棘轮/台账基线形态落地 —— 对新增或变更的 override 有判别力,对既有存量记为已登记基线。⛔ 不做大规模迁移,⛔ 不把存量当作阻塞。
3. ⛔ 不要重修那 13 个桩。 它们已由 PR test(app-shell): stub useRecordPresence as the array the hook returns #8902 修复并以变异测量钉住。本卡问的是下一次,⛔ 不是上一次。

路线优先序(可被测量推翻 —— 这是建议不是裁定)

先试扩既有门而非新铸第三道:本仓已有 check:vi-mock-specifiers 与 check:vi-mock-inherit,第三道同族门是维护成本也是读者负担。⚠️ 但若测出扩门会把「解析 specifier」与「比对 override 值」两种判据糅进一道门、或造成误报风暴,则新开一道边界清晰的门更可取 —— 以测量为准,并在终报里说明为何。

---

⛔ 本卡的验收工具就是变异测量,⛔ 不是绿

立卡席已经证明:把那 13 个漂移桩原样放回磁盘,两道现有门打印逐字相同的 verdict 行与 exit 0。⇒ 一道门在它按设计看不见的类上给出的绿,不是读数。

所以新守卫的唯一合格证明是双向的:

• 漂移在盘上 ⇒ 新守卫红,且点名是哪个桩、哪个导出、期望什么形状;
• 漂移修好 ⇒ 新守卫绿;
• 且两次都要证明变更真的到过磁盘(锚点计数 + blob hash),再读结果 —— 「门没红」和「变更没发生」是同一个输出。

⭐ 立卡席记下的那条尤其要带进设计:{ viewers, others } 这个形状全树只在那 13 个桩里出现过,⇒ 这类漂移是复制粘贴一个邻近但不同的形状,不是误读类型。一个只比对「桩有没有 spread 真实模块」的守卫对它永远无判别力 —— 那正是 check:vi-mock-inherit 今天的盲点。

Zone-2.1 re-derived independently: with the 13 drifted stubs back on disk (blob a3fe5953ac, byte-identical to PR #8902's pre-image) both existing gates print byte-identical verdict lines and exit 0. Route decided on measurement, not preference: injecting `import ts from typescript` into check-vi-mock-inherit.mjs takes check:pre-install-import-graph from exit 0 to exit 1, so extending a sibling would have reddened an existing gate (Zone-1 boundary 2); the new gate therefore lives in lint.yml after install. Zone-1 boundary 3 held with NO ledger entries: 0 mismatches over 923 judged overrides, so KNOWN_SHAPE_MISMATCHES ships empty and the guard is hard-red for this class from day one while the 937 bare-specifier sites are untouched.

ACCEPT — PR #8954 翻 ready + auto-merge

派发席 domain:ui @ objectui,session_01MPaVWWMuWeT5LgB1qoXjVB,2026-09-10T10:1xZ,对 head dac8fe6。⛔ 对 GitHub 核验,不对终报自述核验。

复核清单

项	读数
范围	6 文件,+1234 / −0 —— 零删除
门禁	32 个 check 全部 completed:success 或按设计 skipped,零红
路径面	NOT GOVERNED,带点亮对照
Clause-②	no —— scripts/ 不发布,changeset 声明无发行
changeset	空 frontmatter ✅

门禁 job 级结论:Type Check 09:28:38Z · Test (shard 1..4/4) 09:39–09:40 全 success · Lint 09:29:11Z · Governed Surface Queue Guard · Pre-Install Import Graph Check · Inert vi.mock Specifier Check 全 success。

⭐ 三条本席自己核的,不是采信终报

① Zone-1 边界二(只加强、⛔ 不削弱)是被结构证明的。 git diff --numstat 对 .github/workflows/lint.yml 读出 28 added / 0 deleted,整个 PR 零删除行 ⇒ 没有任何既有门禁步骤被改写或移除。这比"我没削弱"这句话强,因为它不依赖交付席的自述。

② 那道门不只是"接上了",它真的跑了**。** 「Presence in a list is not a reading of effect」—— 所以本席读了 Lint 作业的步骤级结论:

第 14 步 Check every vi.mock override matches the declared export shape · conclusion: success · 09:28:10→09:28:13Z

⛔ 不是 skipped。 一道只挂成 pnpm 别名的门永远不会被 CI 跑,本仓把那视同"门通过了" —— 交付席正是为此才动 lint.yml,而这一步证明它生效了。

③ 那个 if: should_run 条件不是新盲区。 该步带条件门,但忽略清单只有 Markdown 与 content / docs / .changeset 三棵树,而本门比较的两侧(override 与被声明的导出)都住在 TypeScript 文件里;交付席还写了一条测试:若有人往那份忽略清单里加进任何匹配 TypeScript 的模式,该测试变红。⇒ 守卫的可达性本身被守卫。

⭐ 交付轮的三条,值得记进车道

① 本席建议的路线被证伪,而且是"不可用"不是"更差"。 派发令 ZONE 3 建议先试扩既有门。实测:往 check-vi-mock-inherit.mjs 注入 typescript import,会让 check:pre-install-import-graph 从 exit 0 变 exit 1 —— 即弄红一道现有门,正撞 ZONE 1 边界二。⇒ 新开一道门不是偏好,是唯一合法解。本次 CI 上 Pre-Install Import Graph Check = success,独立印证该路线绕开了那个冲突。

② 交付席在那次测量里逮住了自己的假绿。 第一次注入被 shell 引号吃掉,ts-import 锚点计数仍为 0 而门报 exit 0 —— 它弃用了那个读数而不是拿它当结论。「门没红」与「变更没发生」是同一个输出。

③ 结果比本席授权的更好。 我批的是"棘轮/台账基线"以免硬红存量。实测 923 个已判 override、0 处不匹配 ⇒ KNOWN_SHAPE_MISMATCHES 空着发,守卫从第一天就是硬红,而 937 个裸 specifier 站点一个没碰。⛔ 不需要棘轮,边界三以更强的方式满足了。

双向变异,以及一条对自己的对照

13 个文件放回漂移(每个 blob hash 均变且异于 HEAD blob,锚点 grep = 13)⇒ 新门 exit 1,逐条点名哪个桩、哪个导出、期望什么形状;同一次测量里两道旧门仍 exit 0 —— 盲点是并排量出来的,不是引述的。还原后 exit 0,git diff HEAD 空。

⭐ 更值得记的是它给自己的测试加的非空洞对照:两条腿都跑在一个 1001 文件的干净种群上,并且在读状态码之前先断言 stderr 不含 COLLAPSED —— 因为没有填充种群时两条腿都会 exit 1,那时状态码什么都不证明。

两条文件面偏差,已申报,本席接受

.github/workflows/lint.yml 与 content/docs/guide/ci-cd-pipeline.md 都不在申报文件面内。两者都是机制强制而非扩权:前者是"门必须真的被 CI 跑"的唯一落点;后者是因为 scripts/__tests__/ci-cd-pipeline-doc.test.ts 会让任何未被该文档列出的 lint.yml 步骤变红(它是第一次全量 scripts/ 套件里唯一的失败)。⇒ 不列反而不能绿。

落地

翻 ready + auto-merge(SQUASH)。⚠️ 回显再次为空 method(在案陷阱,⛔ 不作读数),按队列 ref 阳性核验,跟到 MERGED。

✅ 已落地 — PR #8954 MERGED;半状态在本笔清掉

派发席 domain:ui @ objectui,session_01MPaVWWMuWeT5LgB1qoXjVB,2026-09-10T10:4xZ。

落地核验 —— 按内容带两向对照,⛔ 不按 sha

origin/main 现为 72bcd7783,恰是本 PR 队列构建所指向的对象 —— 但那只是旁证,判据是内容:

腿	合并前	现在
主体 scripts/check-vi-mock-override-shape.mjs 存在	NO	YES
主体 lint.yml 含步骤名 Check every vi.mock override matches the declared export shape	0	1
正控 .github/workflows/lint.yml 存在	YES	YES
负控 scripts/zzzNoSuch.mjs	NO	NO

两条主体腿同时从缺席转为在场,正控稳定、负控仍缺席 ⇒ 真实状态转移。队列现已清空。

⚠️ 半状态:Fixes 自动关卡不摘 pm:*、不清 assignee

本卡被自动关闭后仍挂着 pm:dispatched 与 assignee。这是本席一小时前在 objectui#8912 上刚踩过并写进座位贴的同一个坑,今天第二次复现 ⇒ 它不是偶发,是这条落地路径的固定产物。

已按〈状态模型〉「关闭即在同一笔摘掉 pm:* 状态标;domain:* 与类型标签留下」清理:pm:dispatched 摘除、assignee 清空;tests / priority:p2 / domain:ui 保留。⚠️ finding 保留未动 —— 本卡已定级 p2,按惯例 finding 应在首次定级时离标,但那是分诊席的产出,⛔ 执行席不代摘。

本卡实际交付的东西

scripts/check-vi-mock-override-shape.mjs —— 第三道 vi.mock 门,比较一个 override 的值形状与真实导出所声明的形状,用 TypeScript AST 顺着 workspace 源入口与再导出链解析。

⭐ 三件比"绿了"更重要的事:

1. 零删除行落地。 整个 PR +1234 / −0,lint.yml 是 +28 / −0 ⇒ Zone-1「只加强、⛔ 不削弱」是被结构证明的,不依赖任何自述。
2. 那道门真的在 CI 里跑。 本席读的是步骤级结论:Lint 作业第 14 步 conclusion: success,⛔ 不是 skipped。一道只挂成 pnpm 别名的门永远不会被 CI 跑,而本仓把那视同"通过了"—— 这正是它必须动 lint.yml 的理由。
3. 台账空着发,守卫第一天就是硬红。 本席授权的是"棘轮基线"以免硬红存量;实测 923 个已判 override、0 处不匹配,所以 KNOWN_SHAPE_MISMATCHES 不需要任何条目,而 937 个裸 specifier 站点一个没碰。⇒ 边界三以比授权更强的方式满足。

⭐ 本轮记进车道的两条

① 本席建议的路线被证伪,且是"不可用"而非"更差"。 往既有门注入 typescript import 会让 check:pre-install-import-graph 从 exit 0 变 exit 1 —— 即弄红一道现有门,正撞 Zone-1 边界二。本次 CI 上该门 = success,独立印证新门这条路绕开了它。

② 交付席逮住了自己的假绿。 第一次注入被 shell 引号吃掉,ts-import 锚点计数仍为 0 而门报 exit 0;它弃用那个读数而不是拿它当结论。「门没红」与「变更没发生」是同一个输出。
