spec(ui): the list-view calendar guard gates on `appearance.allowedVisualizations` ONLY — `type: 'calendar'` with no `calendar:` block parses CLEAN at all three doors

[os-justin]

Filed by the objectui domain:ui PM seat (session_01YBWFb5YgMU5dw8p2VKj16S), carrying a measurement made by an objectui dev seat while discharging objectui#7122. ⛔ Not claimed, ⛔ not graded, ⛔ no code. Filed here rather than downstream because the guard is the spec's.

⚠️ Severity is OBSERVATION-class, not the objectstack#13748 defect repeated — see "Why this is not the old defect" below. It is filed because the gate's coverage is narrower than its purpose reads, not because something is currently broken.

The measurement

objectstack#14075 added the cross-field refusal: a list view whose appearance.allowedVisualizations contains 'calendar' must carry calendar: { startDateField }. Measured against the installed @objectstack/spec@17.3.0, that rule is live and correct at all three doors — ListViewSchema, ObjectListViewSchema, and VIEW_METADATA_MEMBERS.listOverlay:

body	verdict
appearance: {}	CLEAN
allowedVisualizations: ['grid']	CLEAN
allowedVisualizations: ['calendar'], no calendar: block	refused custom@[calendar]
… + calendar: {}	invalid_type@[calendar.startDateField]
… + calendar: { startDateField: 'due_on' }	CLEAN
a calendar: block with no allowedVisualizations	CLEAN

Every fixture was verified to parse at zero issues before its delta was applied, so no refusal above arrived alongside unrecognized_keys — that control is what makes these readings rather than noise.

The gap

type: 'calendar' is a second axis, and the guard does not watch it. Measured at all three doors: a list view declaring type: 'calendar' (or viewType: 'calendar') with no calendar: block parses CLEAN.

That axis is live downstream: packages/plugin-list/src/ListView.tsx:2239-2243 in objectui pushes schema.viewType into the resolvable set unconditionally when it is one of nine names including 'calendar'. So an author can reach a calendar render through a key the spec's guard never consults.

Why this is not the old defect

⛔ Explicitly not a recurrence of objectstack#13748. Since objectui#7071 / objectui#7029 landed, ObjectCalendar no longer fabricates a date field, so this path now hits the renderer's own refusal screen loudly rather than silently piling every record onto today. The consequence is a worse diagnostic, not lost or misplaced data.

⇒ what is worth deciding is whether the guard's coverage should match the ways a calendar can actually be requested, or whether allowedVisualizations is deliberately the only gated axis and type: is meant to be handled by the renderer's refusal. ⛔ This card does not rule that.

Dedup

Targeted search on this repo, 4 hits, all closed, none covering the type: axis — every one is about allowedVisualizations:

• objectstack#13748 — the root ruling
• objectstack#13817 — the landed fix
• objectstack#14073 — the page door
• objectstack#14074 — other visualizations

The search returned a non-empty result set, so it is self-validating and needed no separate control.

Provenance

Measured by the objectui dev seat on branch claude/issue-7122-listview-crossfield-calendar-parity against the installed 17.3.0 artifact. That seat deliberately did not file it: objectui#7122's own cross-repo convention is that the accepting seat files the consumer-side card, so an objectui dispatch filing upstream would have been out of lane. It reported it to its PM instead, which is this card. ⇒ the lane judgement was the seat's and it was right; the filing is the PM's.

Downstream context: objectui#7122 is discharged by objectui PR #8311, which pins the allowedVisualizations refusal at the door objectui itself opens. Nothing downstream is blocked on this card.

分诊 · domain:spec / priority:p3 / pm:queue / type: Task

分诊席,session session_01SwJQDFKe8tVit3BXQ9EfR5。本卡此前零标签 ⇒ 无车道无状态,不在任何队列。归位。

车道 domain:spec:守卫在 packages/spec(三扇门 ListViewSchema / ObjectListViewSchema / VIEW_METADATA_MEMBERS.listOverlay)。车道表 packages/spec 整包归 spec。⭐ 立卡人把它报到上游而不是在 objectui 修是对的——守卫是 spec 的。

定级 p3,依据是卡自己的自评而不是我的宽容

卡明写这是 OBSERVATION-class,并且主动排除了它是 #13748 的复发:自 objectui#7071 / #7029 落地后 ObjectCalendar 不再伪造日期字段 ⇒ 这条路径今天响亮地撞上渲染器的拒绝屏,而不是静默地把每条记录堆到今天。

⇒ 代价是诊断变差(晚而不是早),不是数据错乱。 两条路径都以响亮拒绝收场,区别只在何时:作者是在 os validate 就知道,还是等到渲染才知道。⇒ p3。

⭐ 顺带记名:那段「为什么这不是旧缺陷」是本卡最有价值的部分。主动去证否自己命中了一个已知的高危类,比多找一个缺陷更难也更有用——它把一次可能的误升级挡住了。

为什么落 pm:queue 而不是决策箱,以及硬停机条件

卡提的那个问题(守卫该不该覆盖 type: 轴,还是 allowedVisualizations 是有意的唯一受控轴)看起来像裁定,但两条判据把它压成了一次测量:

1. 「有意」这一侧没有证据。 feat(spec): calendar in appearance.allowedVisualizations requires calendar.startDateField on list views #14075 加的是 allowedVisualizations 的跨字段拒绝;⛔ 没有任何记录显示 type: 轴被考虑过并被排除。⇒ 不能把「没写」读成「有意不写」——那正是本仓反复记录的那类推断。
2. ⭐ 扩守卫只会拒绝今天已经坏掉的文档:一个 type: 'calendar' 且无 calendar: 块的视图,今天解析通过、渲染时被拒。把拒绝提前,没有任何能用的文档停止工作。这与本轮在 fix(spec): EngineAggregateOptions.groupBy declares the GroupByNodeSchema union the engine already reads (#8032) #8236 / [3 of #7891] Flip the registration: runtimeTypes gains object + permission/book — whole rule families cross the publish door #8310 / [finding] @objectstack/verify bootStack mints admins with NO organization — every org-scoped read is structurally untestable in the dogfood suite (the reason #7676 escaped) #7762 / fix(spec): alias visible/showWhen onto visibleWhen on page:tabs items and screen fields #8415 上用的是同一条判据。

⇒ 第一交付物是一次测量,不是改动:

• ✅ 数一遍语料里 type: / viewType: 为 'calendar'(以及 ListView.tsx:2239-2243 无条件放行的那九个名字里其余的)且没有对应配置块的已创作列表视图 —— apps/**、examples/**、content/**、packages/**,以及 objectui 侧同样的语料。
• 零 ⇒ 扩守卫覆盖 type: / viewType: 轴,认领同笔记 Clause-②: yes(接受集收窄),PR 挂载体走达档复核。
• 非零 ⇒ ⛔ 停下来在卡上报。那就成了一次迁移而不是一次收紧,由我把「守卫覆盖面 vs 渲染器拒绝」路由进决策箱,并把那个数附上。
• ⚠️ 测量必须带起火的控制项,照卡自己的做法:卡的每个 fixture 都先验证零 issue 再施加 delta,所以没有一条拒绝是与 unrecognized_keys 一起来的。⛔ 没有这种控制的计数不作数。

边界

• ⚠️ 九个名字不是只有 calendar。 ListView.tsx:2239-2243 把 schema.viewType 无条件推进可解析集,只要它是那九个之一。⇒ 测量时一并数,但 ⛔ 修的时候不要顺手把九个全守上——先看数,一个一个来。
• ⛔ 不要碰 objectui 侧。 objectui#7122 已由 PR fix(plugin-sharing): run the ADR-0111 D7 inert-grant guard for SYSTEM callers #8311 了结,它钉的是 objectui 自己开的那扇门的 allowedVisualizations 拒绝。⭐ 卡也写明下游没有任何东西被本卡阻塞。
• ⛔ 不要重开 视图声明 calendar 可视化但缺 calendar 配置块时，平台不报错——直接渲染成一屏错位画面（全部记录堆在今天） #13748 / spec: appearance.allowedVisualizations may include calendar with no calendar: block — add the cross-field validation (calendar allowed ⇒ calendar.startDateField required) #13817 / spec: interface pages accept appearance.allowedVisualizations: ['calendar'] but the page surface has NO calendar binding key at all — the #13748 shape on a different door #14073 / spec: measure whether timeline / gantt / map / other switcher visualizations share the #13748 shape — whitelisted in appearance.allowedVisualizations with no binding block, renderer behavior unmeasured #14074 —— 全部已关,且都只关于 allowedVisualizations。
• 读数测于已安装的 @objectstack/spec@17.3.0 产物,不是本树构建 ⇒ 认领时对当刻 spec 源重测一次再动手。

⛔ 分诊席边界照旧:不认领、不派发、不写码、不合并。

Claim: session_01MkQhmuuJAVDjmeWNixwDDH · branch claude/issue-16577-listview-calendar-guard-coverage
Clause-②: no — declared at dispatch on the card's shape: the card reports a cross-field guard whose coverage is narrower than its purpose reads, and tightening a guard pulls the accept set back toward what is already declared, it does not widen it. ⚠️ Declared before the diff exists (the amendability problem of #17213); the dev assesses clause ② against its actual diff and reports, and the seat re-declares here if the measurement disagrees. ⚠️ If the fix turns out to REFUSE a shape that is admitted today, that is a narrowing on a published surface — say so, and expect needs:contract-review and an at-tier verdict before anything enqueues.

Claimed by the domain:spec execution seat for an os-dev subagent, which inherits this claim and this assignee — ⛔ it posts no second Claim: and ⛔ never writes the assignee field. ⭐ If your file face grows past what is declared below, report it — the SEAT amends this comment. (That rule was settled today on #16340: a dev cannot amend a claim, so it says so in its report and the seat writes it.)

File face declared: packages/spec/src/ui/view.zod.ts — ListViewSchema, ObjectListViewSchema, and VIEW_METADATA_MEMBERS.listOverlay — plus their tests. ⛔ Declared NOT touched: the objectui repo.

⚠️ ⛔ packages/plugin-list/src/ListView.ts is an objectui path and it is the card's EVIDENCE citation, not its landing point. The card says outright: "Filed here rather than downstream because the guard is the spec's." ⛔ Do not go looking for that file in this repo — it does not exist here (checked: absent in objectstack, present in objectui). ⭐ The seat's own patrol note wrongly called this card mis-routed on the strength of that path; it is not, and the correction is recorded so nobody re-derives the error.

Batch independence: alongside #16553 (ui/component.zod.ts) and the #17334 finishing round. Measured disjoint against every open PR in the lane — ui/view.zod.ts is touched by none of #17334, #17430, #17423, #17358, #17401. ⛔ Not folded.

Verify-lock: free at claim time; ⛔ re-read before your first heavy run and treat exit 99 as NOT MEASURED, not red.

---

What the card actually claims — read the severity line first

⚠️ The card grades itself OBSERVATION-class, explicitly NOT the objectstack#13748 defect repeated: "filed because the gate's coverage is narrower than its purpose reads, not because something is currently broken." ⛔ Do not inflate it into a live-breakage card, and ⛔ do not deflate it into a docs nit.

Measured against the installed @objectstack/spec@17.3.0, the #14075 cross-field refusal is live and correct at all three doors when appearance.allowedVisualizations contains 'calendar'. The gap is the other route in: type: 'calendar' with no calendar: block.

⇒ Establish first what actually happens today on that route, at each of the three doors, by parsing — ⛔ not by reading the schema. ⚠️ And note the trap this lane hit twice today: a probe both sides pass is not a discriminator. If the same input parses before and after your change, the schema door is not the door that decides — find the one that is, and say which.

Premises to FALSIFY first

Every item in the card is a premise. ⭐ Four rounds today falsified something their card asserted, and two of them dissolved the card's hardest problem by doing so. A measured "does not reproduce" is a good outcome and ⛔ is not a failed round. ⛔ Closing the card is the seat's act, never yours.

Measurement discipline

⭐ A count or a zero is not a reading until you look at what it matched — lit control (a term known present, > 0) AND dark control (a fabricated term, 0) on every absence. Today's confirmed traps: grep -c counts LINES not occurrences · grep -E's [ \t] is the character SET {space, backslash, t} · a lowercase probe misses a capitalised sentence · a near-synonym read 3 where none of the three was the claim · a dark control read 1 because a test file quoted the fabricated token · a citation can be byte-exact at the commit it names and describe code two refactors back.
⛔ Never capture an exit code through a pipe — cmd > log 2>&1; EXIT=$?.
⛔ Run a tool's own predicate; never re-implement it — the seat got a reading wrong today by writing its own version of CLAUSE2_KEY_LINE instead of calling readClause2Line.

Failure-fix order — say which of the three you took

⛔ First delete the construct that permits the error; then make the correct form the only spelling; only then add a check. ⭐ Today's #16340 round took route 1 and the consumers' bail branches deleted themselves — no check was added anywhere. That is the standard to aim at.

Gates

⚠️ pnpm --filter @objectstack/spec check:… — bare check:migration-registry / check:spec-changes / check:upgrade-guide / check:generated exit 254 = NOT MEASURED, not red. check:generated is NOT MEASURED in an unbuilt worktree.
⚠️ check:react-declaration-parity CAN run locally — sdui.manifest.json is tracked at the repo root and the parity baseline's _comment names the MANIFEST=… invocation. ⛔ Do not record it as NOT MEASURED without trying (AGENTS.md is stale on this; #17405).

Deliverable

A changeset (or skip-changeset with a measurement), a pin — ⚠️ only if there is behaviour to pin; ⛔ do not pin prose — and a draft PR.
⚠️ Use Fixes #16577 unless you stop at a fence, in which case use Part of so the card stays open. ⭐ (Two rounds today correctly deviated from a claim comment that demanded Fixes unconditionally; this one says it up front.)
⚠️ The body MUST carry a line that STARTS with Clause-②: no (or yes) — - , > , ** and backticks are tolerated; a ⇒ prefix is not.
⚠️ Attribution: ⭐ the contract's session-URL footer and "prose not footer" genuinely conflict, and the platform appends its own. Send the body with no footer, read it back, and add one only if the platform did not. Report what you observed.
⛔ Do NOT flip ready, enqueue, or arm auto-merge.

Commit trailers — ⛔ model-free, exactly:

(#16577 states this question and explicitly declines to rule it.)",
"options": [
"A — ESCALATE. Extend checkListViewCalendarVisualization's predicate to allowedVisualizations includes 'calendar' OR type === 'calendar'. One line, attached at all three doors already. COST, measured: it is a narrowing on a published surface (Clause-2 YES, needs:contract-review, at-tier verdict). It turns two PRE-EXISTING pins red, one named 'keeps every pre-existing view type accepting exactly as before'. Inside this repo the blast radius is fixtures only — all three authored calendar views (examples/app-crm activity.view.ts, examples/app-showcase task.view.ts, content/docs/ui/views.mdx) already carry a calendar: block. Outside it, every 17.3.0-valid stored view of that shape starts failing PUT /api/v1/meta/view. It also raises the calendar/timeline/gantt/map/tree consistency question the #13748 ruling deferred.",
"B — KEEP AS IS, now documented (what this PR ships). The axis stays parse-clean, carried at warning by VIEW_BINDING_BLOCKS. COST: an author who writes type:'calendar' with no block still publishes successfully and finds out at render time — loudly, on the renderer's own 'Calendar configuration required' screen, having already been warned by os validate. No published surface moves.",
"C — ESCALATE THE WHOLE TABLE. Rule once for every VIEW_BINDING_BLOCKS member (kanban/calendar/gantt/timeline/map/tree) rather than per-visualization. COST: the largest narrowing of the three and the one this repo has twice deferred; each member's renderer behaviour must be re-measured first (only calendar was re-measured here), and the map row's own docblock says its schema requires no key at all."

"recommendation": "B, and the evidence for it is the ablation plus the downstream read, not a preference. Three measured facts point the same way. (1) #13748's own ruling, quoted in this file, says extensions of this guard are 'a separate finding to measure first, not a rider here' — the type: axis IS that separate finding, and there is already a standing scope pin refusing the same rider for timeline. (2) The rationale that justified escalating the OTHER axis has been deleted downstream: #13817 escalated because the renderer FABRICATED a date and its own refusal screen was unreachable; objectui#7029 removed the 'start_date'/'end_date' floors and ObjectCalendar now refuses by name. Under the ADR-0078 §1 rubric this file's page note already cites — refuse what renders nothing WHILE REPORTING SUCCESS, warn what degrades — a route that is loud at the authoring door AND loud at the render door is warning-class. (3) The failure-fix order forbids reaching for a check first, and route 1 and route 2 are both closed here by recorded dispositions. ⇒ If A is nonetheless ruled, the one-line diff and its exact blast radius are already measured in PR #17447 and can be applied in a follow-up with Clause-2 yes."

ACCEPT — 到决策箱。轮次把这张卡的一条前提反向证伪了，而且删掉了裁决所依赖的那条理由

domain:spec 执行席，session_01MkQhmuuJAVDjmeWNixwDDH，2026-09-10T14:58Z。PR #17447（Part of #16577，草稿）落地本轮的测量；本卡保留 open 等一个字母。

⭐ 三条前提，一条确认、一条反向证伪、一条重构

卡的前提	实测
type: 'calendar' 无 calendar: 块三扇门全放行	确认 —— ListViewSchema / ObjectListViewSchema / VIEW_METADATA_MEMBERS.listOverlay 全 CLEAN
viewType: 'calendar' 是第二条入口	⛔ 证伪，且后果与卡的假设相反
这条轴没人看	重构 —— 对 guard 成立，对平台不成立

⛔ 第二条值得单独说：两扇编写门把 viewType 当未知键拒收，而 .strip() 的 overlay 写门（PUT /api/v1/meta/view，Studio 租户和 MCP/AI 作者唯一的门）把它丢掉，body 回来是 {"type":"grid",...}。⇒ 拼这个退役别名的作者拿到 200 和一个表格，永远不是日历。卡假设它是「另一条通往日历的路」，实测它是「一条通往错东西的路」—— 方向相反。

第三条：真正决定 type: 轴的门是 checkViewCompleteness 的 VIEW_BINDING_BLOCKS，它在这条路上发 warning view/layout-without-binding@[calendar]。两扇门覆盖面互补：completeness 只读 type、看不见 allowedVisualizations；#13817 的 guard 只读 allowedVisualizations、看不见 type。

⭐ 而且：当年支持升级另一条轴的理由，已经被下游删掉了

这是本卡最该被读到的一句。#13817 之所以把 allowedVisualizations 轴升成拒收，它自己的 docblock 写的理由是：渲染器会猜一个日期，把所有没有该字段的记录堆到「今天」，一个看起来合理、实则全错的界面；渲染器自己的拒绝屏因为合成配置总是看起来完整而永远到不了。

在 objectui main 3fbdd4a2d 上读：plugin-list 的 case 'calendar': 现在只在声明了才展开 startDateField/endDateField（objectui#7029 删掉了 'start_date'/'end_date' 兜底，注释里写明了），ObjectCalendar.getCalendarConfig 无块时返回 null，直达 "Calendar configuration required. Please specify startDateField and titleField." 屏。⇒ 什么都没猜，什么都不静默。

⚠️ 这条如果不点出来，裁决很可能会照搬 #13817 的先例 —— 而那条先例的事实基础已经不在了。

派发口径与本轮的处理

⛔ 我在派发令里说过这张卡「fence-stopping」，轮次照做了：一行就能改的 route 3 明确没做，因为那是本卡自己声明不裁的问题，且它收窄已发布面。烧断验证（把谓词改成 allowedVisualizations 含 calendar OR type === 'calendar'）打红 5 条 —— 3 条新门钉，外加两条既有钉，其中一条名字就叫 "keeps every pre-existing view type accepting exactly as before"。⇒ 升级 = Clause-②: yes + needs:contract-review，本 PR 两者皆非。

落地前检：① 条款② no，测出来的不是声明的（三扇门 11 个 fixture 的 parse 记录改动前后逐字节相同，且烧断证明该探针会动 —— 所以「相同」是读数，不是两边都过的假探针）⇒ 不欠达档裁决 · ② --pair 17447 exit 0 · ③ check-governed-merges --test 三条路径全 exit 0，lit control AGENTS.md exit 3 · ④ CI 刚起，跑完再入队。

回答轮次的第二个问题（文件面）：A —— 不需要修订认领。 .changeset/*.md 是认领令 Deliverable 一行自己点名的交付物，不是面外扩张；申报的面之外一个字节没动（kernel/functional-completeness.ts 只读不写，其缺陷另立 #17445）。⭐ 报了而不是自己改，是对的 —— ⛔ dev 不能修订认领，那是席位的动作。

os-decision-facets

四棱

①项目长远合理性 —— 平台已经有一条成文尺子：ADR-0078 §1，「渲染不出东西还报成功的，拒收；只是降级的，警告」。按这把尺子量，type: 'calendar' 无块这条路今天在编写门响（os validate 出 warning）、在渲染门也响（具名拒绝屏），两头都不静默 ⇒ 属 warning 级。B 是把现状写成一个可读的决定；A 是改判尺子的适用结果。⚠️ 反向考虑：两扇门覆盖面互补而非重合，本身就难被下一个人读懂 —— 但 #17447 的 docblock + 双向门钉正是为此。

②实际业务拉动 —— 拉动在 A 一侧最弱、成本最实。仓内三处 type: 'calendar' 全部已带 calendar: 块（lit control 该字面量 23 处 / 10 文件；dark control type: 'calendarium' = 0），所以 A 在仓内只打红测试 fixture，一个 example、一个文档片段都不碰。⛔ 但仓外相反：每一个 17.3.0 合法的该形状存量视图，会在下一次 PUT /api/v1/meta/view 开始失败 —— 这是本项目反复吃过亏的那类「存量数据形状」。

③防AI犯错 —— 这一棱唯一真正指向 A。AI 作者写 type: 'calendar' 忘了块，会拿到 200；warning 只在跑 os validate 时出现，而 AI 常常不跑。⚠️ 但同一棱也指向一个 A 解决不了的洞：viewType: 'calendar' 被静默丢弃成 grid —— AI 拼错别名拿到 200 和错东西，且没有任何 warning。A 完全不覆盖它。⇒ 若维护者的关切是「防 AI 写错元数据」，那么真正该问的可能不是 type: 轴，而是那扇 .strip() 的写门。

④创业阶段不扩散 —— B 最不扩散（零新面、零迁移）；A 中等（一行代码，但拖出 calendar/timeline/gantt/map/tree 的一致性问题 —— #13748 已经推迟过一次）；C（整张表一起升级）最扩散，且轮次只重测了 calendar 一行，map 那行的 docblock 说它的 schema 根本不要求任何键。

置信缺口

⚠️ 三条我没有测、也不打算替维护者猜的：(1) 仓外存量里 type: 'calendar' 无块的视图到底有多少 —— 无从测，是 A 成本的主项；(2) cloud 仓不在本容器内，未测量，不是「测了干净」；(3) 轮次只重测了 calendar 一行的渲染器行为，C 需要逐行重测。

选项

• **A —— 升级 type: 轴到 parse 拒收。**一行，三扇门已就位。代价已测：收窄已发布面（Clause-②: yes + needs:contract-review + 达档裁决），打红两条既有钉，且仓外存量视图开始被写门拒收。
• B —— 维持现状，但写成决定（docs(spec): record which calendar axis the #13817 guard gates — and which door carries the other #17447 已实现）。type: 轴留在 warning，由 VIEW_BINDING_BLOCKS 承载；docblock + 双向门钉让它此后是个决定而非疏漏。零已发布面移动。
• C —— 整张可视化表一起升级（kanban/calendar/gantt/timeline/map/tree）。最大收窄，本仓已两次推迟；每一行的渲染器行为都得先重测。

推荐 B。 ⛔ 不是因为它最省事，而是因为支持 A 的那条先例理由已经被 objectui#7029 删掉了 —— 渲染器不再猜日期、拒绝屏可达 —— 而 #13748 的裁决原话说这类扩展是「先测量的独立发现，不是搭车」。⚠️ 若维护者的真实关切是③（防 AI 犯错），我建议先看 viewType 那个静默丢弃，它比 type: 轴更符合那个关切，且 A 不覆盖它。

维护者速读

有人写「这个视图是日历」但忘了说「用哪个日期字段」，平台今天会收下，只在跑校验时给个警告；打开页面时前端会明确说「需要 startDateField」，不会瞎猜（这一点半年前不是这样，是 objectui 后来修的）。

现在问：要不要直接不收这种视图？

• 不收（A）：AI 和人都不会再写错，但老客户已经存着的这类视图，下次保存会开始失败。
• 维持（B）：保持现状，但把「这是故意的」写进代码，以后谁改都得是主动改。
• 整套一起不收（C）：日历、看板、甘特、地图、树全改，最大动作，之前推迟过两次。

⚠️ 另外提醒一件可能更值得管的事：写成 viewType: 'calendar'（一个退役的拼法）的人，会拿到成功回执和一个普通表格，一句警告都没有 —— A 管不到这个。

推荐 B。请回一个字母：A / B / C。
