   Read fresh. PageTypeSchema promises that home is "the platform-level landing page" and that utility is "a floating utility panel". But:

   • the landing is the first navigation item (HOME_PAGE_ID_RETIRED, objectui findFirstRoute);
   • both types render as ordinary inline region pages;
   • a non-record page's isDefault: true is accepted, stored, served and read by nothing.

   HotCRM shipped exactly that shape, measured on 18.0.0-next.1.

   Two halves:

   1. The text (no decision needed). The enum comments and the doc block say what the runtime does: home is a wide region page, and the landing is the first navigation item; utility has no floating slot. This is ADR-0049's rule applied to the promise. It lands as a fix.
   2. isDefault on a non-record page (a conditional protocol card). It is either refused at validate, with a prescription naming the navigation order, or given a meaning, which would be a declared landing.
      • Refusing it narrows what the spec accepts, and a shipped consumer sets it (HotCRM).
      • Giving it a meaning is a feature.
      • So the domain:spec seat presents it as a decision with the facets. ⛔ It is not chosen inside a fix PR.

   • priority:p1 + target:v18: half 2's outcome may refuse a key, so its verdict lands before GA (filing-gate.md 〈定级判据〉, 「可退役键的条件卡同档」).
   • A utility shell slot is a feature widening, held for the maintainer to name. Not here.
   • Lane domain:spec (packages/spec/src/ui). objectui's page renderer is unchanged by half 1.

   Same seam, one more declared shape the renderer does not deliver: region NAMES. Folded here rather than filed separately (repo:hotcrm seat, session_01P8mZuzuyZAHSrgQKmv6ASv, 2026-10-15T05:06Z). ⛔ Not a claim.

   • Named producer: HotCRM src/sales/pages/home.page.ts (sales_home_page) declares template: 'three-column' with regions header, left_sidebar (width: 'small'), main, right_sidebar (width: 'medium').
   • Renderer: objectui origin/main 7c13d30 packages/components/src/renderers/layout/page.tsx, ThreeColumnTemplate (L407-430), slots regions by the exact names header / sidebar / main / aside / footer (findRegion, L87; L412-415). Every other region goes to getRemainingRegions and is stacked under main at full width, and its declared width is dropped.
   • Measured by the seat's dev as na.rep on fix(nav): hide the opportunity-built entries from members who cannot read opportunities, and give Sales Home a sidebar entry hotcrm#2117 (report on Browser pass #2058 — HotCRM-side defects (18 items: accepted quote still takes lines, half-converted leads, agents losing their cases, unreachable Sales Home, …) — list card, split per item at dispatch hotcrm#2060): 0 aside nodes; right_sidebar drawn at x=280, w=1136, below main. pnpm validate exits 0 with no word on it.
   • Spec: PageSchema.template and regions[].name are free strings. The slot names a template honours are declared nowhere in the spec, so neither an author nor os validate can know that left_sidebar is not a sidebar.
   • Expected: a template's slot names are part of the contract (an enum per template, or a refusal at validate for a region name the chosen template will not place), or the renderer places regions by role rather than by exact name.

   Claim: PM loop round 2 (second shift) · 2026-10-15T05:24Z · half 2 of triage 6184773490 (a non-record page's isDefault) and the fold-in 6184870296 (a template's region names) as this seat's decision presentation, reading-only. Half 1 (the home / utility promise text) waits to ride the ruled execution PR, so the card carries one PR and one contract review.
   Session: session_01LFqdRsuM5nkqoJdHd5ztVk
   Account: os-bill (the seat's linked user as GET /user answers it; always the card's assignee)
   Branch: none (the presentation writes no code)
   Worktree: none
   Domain: domain:spec
   Seat: domain:spec#2 (seat post #18549)
   File surface: none in this act. For the record, the execution PR's expected surface is packages/spec/src/ui/page.zod.ts (the PageTypeSchema docblock and enum comments, the utility print refusal's "floating panel" message at :1505, isDefault), packages/spec/src/ui/page-print.test.ts, the type and isDefault rows of packages/spec/liveness/page.json, and skills/objectstack-ui/rules/pages.md (:26 and the Templates & Regions names) as a separate Tier H PR.
   Container & model: the presentation is written in-seat at the seat's tier; no dev is dispatched in this act
   Clause-②: no (this act)
   Responsibility: PageTypeSchema's docblock and enum comments, isDefault's non-record arm, and skills/objectstack-ui/rules/pages.md | none: os validate passes all three shapes in silence | HotCRM's sales_home_page (type: 'home', isDefault: true, regions left_sidebar / right_sidebar) and utility_bar_page (type: 'utility'), measured by the repo:hotcrm seat on 18.0.0-next.1
   Thread-read: 6184870296
   Serial constraints cleared: no code in this act. When the execution PR is dispatched, my own #23434 branch (claude/issue-23434-sha-less-read-points) edits liveness/page.json's regions row note, and that PR waits on it or merges main after it. No open PR touches page.zod.ts, page-print.test.ts or skills/objectstack-ui/rules/pages.md (all 13 open PRs' file lists were read in this act). PR #23418 (#23388) touches packages/lint/src/validate-print-page-blocks.ts, not the spec refinement.

   待裁:#23610 两问 · 非记录页上的 isDefault;模板的区域名 · domain:spec seat 2 · 2026-10-15T05:30Z

   Session session_01LFqdRsuM5nkqoJdHd5ztVk · os-bill. This presentation follows triage 6184773490 (half 2 goes to a decision; ⛔ it is not chosen inside a fix PR) and the fold-in 6184870296, under claim 6185099470. Facts were read from source at objectstack origin/main dd4ef3850 and objectui origin/main cfbca7f. HotCRM was not read by this seat: its facts are the repo:hotcrm seat's measurements on this card. Nothing was run end to end.

   维护者速读

   • Q1 · 一句话:作者给首页(type: 'home')标 isDefault: true 想让它成为落地页。校验通过、保存、下发,但什么都不发生:没有一扇门读它,也不说一个字。
   • Q2 · 一句话:作者把区域起名 left_sidebar / right_sidebar(我们自己的 skill 就这么教),写进 three-column 模板。校验通过,但渲染器只认 header / sidebar / main / aside / footer,其余区域整宽堆到正文下面,声明的宽度也被丢掉。模板名同理:skill 教的 two-column / single-column 不存在,会静默退回默认布局。
   • 谁撞上了(实测):HotCRM 两条都中(sales_home_page)。本仓 examples/app-showcase 的 showcase_capability_map 也是 type: 'home' + isDefault: true;它确实是落地页,但那是因为它排在导航第一位,不是因为这个标。
   • Q1 选项:A 在每扇门拒绝非记录页的 isDefault: true,拒绝语点名真正的落地方式(导航第一项;根落地看应用的 isDefault);B 赋予它「声明落地页」的含义(新功能);C 现状照收,只改文字。推荐 A。
   • Q2 选项:A spec 把模板收为渲染器注册的封闭清单,每个模板声明自己的槽位,放不进的区域名在校验与保存时拒绝并列出槽位;B 渲染器按角色认名(left_sidebar → sidebar),spec 不变;C 只改 skill 和文档。推荐 A。
   • 半边 1(home / utility 的承诺文字,无需裁)随裁后执行 PR 一起落。utility 的悬浮外壳槽是功能扩张,分诊已说留给维护者点名,本呈不涉及。
   • 请回:Q1 A/B/C · Q2 A/B/C。

   Facts (cited)

   1. isDefault's one meaning. PageSchema.isDefault (packages/spec/src/ui/page.zod.ts, the isDefault: describe) is "the default record page of its object"; "outside this rule for a page that is not a record page bound to an object". defaultRecordPageObject (packages/spec/src/ui/default-record-page.ts) answers undefined for home, app, utility and list. The three doors that read it (defineStack, objectql registration, saveMetaItem) judge only record pages. Ruling A on spec(page): no stated rule decides between two isDefault record pages for one object, so the renderer cannot honour isDefault without inventing precedence (the spec half of objectui#12195) #23015 (record 6134056653), landed by PR feat(spec,objectql,metadata-protocol)!: one default record page per object per deployment, a second refused at os validate, registration and save (#23015) #23206.
   2. No reader of a non-record page's isDefault. objectstack: no reader outside defaultRecordPageObject's callers (git grep -n isDefault origin/main -- 'packages/*/src/**', read for page sites). objectui: the app landing is resolveLandingRoute → findFirstRoute(activeApp.navigation) (packages/app-shell/src/console/AppContent.tsx). The root landing reads the APP's isDefault (RootLandingRedirect.tsx, homePath.ts). usePageAssignment reads no isDefault on any page (its own comment: "nothing in this decision reads it"). That last fact is the open record-page half, objectui#12195.
   3. The landing's governing text. HOME_PAGE_ID_RETIRED (packages/spec/src/ui/app.zod.ts, docblock above it) says: "an app's landing page IS its first navigation item in order, and the ROOT landing follows isDefault routing". If a declared landing is wanted again, "it belongs on the navigation item itself (a navigation[].landing-shaped marker …), designed enforce-first". A page names no app, so a page-level flag cannot say WHICH app it lands.
   4. Producers of Q1's shape. HotCRM src/sales/pages/home.page.ts (sales_home_page, type: 'home', isDefault: true), per the card. Here: examples/app-showcase/src/ui/pages/capability-map.page.ts (type: 'home', isDefault: true), which is also the first item of ShowcaseApp.navigation (examples/app-showcase/src/ui/apps/index.ts, "First item = the app's landing surface"). No other example, platform or template page sets it.
   5. What the renderer places (packages/components/src/renderers/layout/page.tsx):
      • TEMPLATE_REGISTRY holds exactly default, full-width, header-sidebar-main, three-column and dashboard. An unregistered name falls back to the page-type layout (resolveTemplate returns null).
      • The default/page-type layout and three-column place header, sidebar, main, aside and footer. header-sidebar-main places header, sidebar and main. dashboard places header and footer, and grids every other region by design.
      • Every other region goes to getRemainingRegions and is stacked under main. Only slotted regions read width (getSidebarWidthClass / getRegionWidthClass).
   6. What the spec says. template: z.string().default('default'), an example "header-sidebar-main"; PageRegionSchema.name: z.string(), an example "sidebar", "main", "header"; width is an enum. No template's slot set is declared anywhere. The liveness rows template and regions (packages/spec/liveness/page.json) record the slots as objectui citations only.
   7. Who teaches the wrong names. skills/objectstack-ui/rules/pages.md:38-40: templates 'three-column', 'two-column', 'single-column'; regions header, left_sidebar, main, right_sidebar, footer. Two of the three templates and both side names do not exist in the renderer. content/docs/ui/pages.mdx authors a content region (stacked). First-party pages otherwise stay inside the slots: examples and platform pages use header, main and sidebar, with templates default and header-sidebar-main (a census of every regions: [ block in examples/**, packages/platform-objects/src/**, content/docs/** and skills/**). No Studio surface in objectui writes a template (git grep -E 'header-sidebar-main|three-column' → the renderer only).
   8. Half 1's sites (rides the execution PR):
      • PageTypeSchema's docblock (page.zod.ts, "home is the platform-level landing page … utility is a floating utility panel") and its enum comments;
      • the utility print refusal's message ("a utility page is a floating panel beside the page a user is on …") and its pin in page-print.test.ts;
      • the liveness type row;
      • content/docs/ui/pages.mdx ("home | Landing/home page | App entry points");
      • skills/objectstack-ui/rules/pages.md:26 (Tier H).

   Q1 · a non-record page's isDefault: true

   Option	What it does · what a customer sees	Workload
   A · refuse	Every door (os validate, registration, save) refuses isDefault: true on a page defaultRecordPageObject does not place. The refusal names where a landing is actually set: the app's first navigation item, and the APP's isDefault for the root landing. The author hears at once instead of shipping a dead flag. BREAKING for HotCRM's page and for this repo's showcase example (the example drops the flag in the same PR, and its landing is unchanged).	domain:spec · 1 PR (a PageSchema refinement, a semantic migration entry the way the 18.ui-*-refused entries do it, the example, the describe and the liveness isDefault note) · precedent PR #23331 (+482/−56, 9 files, a refused page combination)
   B · give it a meaning	The flag starts choosing a landing page. A page names no app, so this needs a page→app binding or a tie-break that no author wrote. It also reopens the direction HOME_PAGE_ID_RETIRED recorded (a landing marker belongs on the navigation item).	spec + objectui (resolveLandingRoute) + rules for two defaults · no precedent
   C · status quo, text only	The describe and the docs say the flag does nothing on these pages. It is still accepted in silence.	1 small PR, inside half 1

   In business terms. A: like a form that will not let you tick a box that controls nothing, and points to the box that does. B: building the box's wiring, for a box that sits on the wrong form. C: printing "this box does nothing" beside a box people keep ticking.

   Q2 · a template's region names

   Option	What it does · what a customer sees	Workload
   A · declare the slots, refuse the rest	template closes to the templates the renderer registers, and each template declares its slots in the spec. A region the chosen template will not place is refused at os validate and save, naming that template's slots (dashboard keeps its open grid, by design). The author of left_sidebar learns sidebar before shipping. The renderer's stack-the-rest branch becomes unreachable for authored pages (an objectui follow-up).	domain:spec · 1 PR (the template enum and slot table, the refinement, a semantic migration entry, the liveness template / regions rows, the docs snippet) + the Tier H skills row + 1 objectui card · precedent PR #23331's shape (+482/−56); no precedent for a vocabulary shared across repos
   B · renderer reads by role	objectui maps left_sidebar to sidebar, right_sidebar to aside, and so on. The spec stays free text, so the next unforeseen name is stacked again in silence.	objectui · 1 PR · no precedent
   C · text only	The skill and docs name the real slots and templates. Nothing refuses a wrong name.	1 Tier H skills PR + docs, inside half 1

   In business terms. A: the floor plan lists its rooms, and the builder refuses furniture addressed to a room that does not exist. B: the movers guess which room you meant. C: a corrected floor plan, with every delivery still accepted at the door.

   Four-axis analysis (business standpoint)

   • Long-term soundness (decides the letter).
     • Q1-A keeps one key with one meaning (the record default) and closes the arm that means nothing. The landing stays where HOME_PAGE_ID_RETIRED put it, and a future landing marker lands on the navigation item, enforce-first. Q1-B builds a second landing mechanism on an object that names no app. Q1-C keeps a key that says one thing and does another.
     • Q2-A makes the layout vocabulary part of the contract, which is where an author and os validate can see it. Q2-B moves guessing into the renderer. Q2-C keeps it undeclared.
     • End state in two years: a page template is a closed list, and each template publishes its regions. A misplaced region is refused when the page is saved. An app's landing is declared on its navigation. Salesforce Lightning App Builder has the same shape: fixed template regions, and the home page set per app, not by a flag on the page.
   • Real business pull.
     • Q1: one external producer (HotCRM), plus our own example, whose flag is decorative. Nobody relies on the flag doing anything, because it does nothing.
     • Q2: HotCRM shipped a three-column home page drawn as one column. The wrong names come from our own skill, so every AI-authored page that follows it repeats the mistake.
   • Making AI mistakes harder.
     • Q1-A and Q2-A both turn a silent no-op into a loud refusal with the correct spelling in it: the author sees the error at os validate, before a user sees a wrong page.
     • Q1-C and Q2-C leave the failure visible only to the end user: a landing that does not land, a sidebar drawn under the content.
     • Q2-B hides the mistake and invites the next one.
   • No requirement creep.
     • Q1-A and Q2-A add no capability. They narrow two free surfaces to what already runs.
     • Q1-B is a new feature. Q2-B adds an alias table to maintain forever.
     • Retiring immediately (no grace window) applies: the one external producer is named, and its edit is a deletion or a rename.

   Recommendation: Q1 A, Q2 A. Fallback: Q1 C (if refusing a shipped key before GA is not wanted, the text says the truth and the flag stays inert), Q2 C (if the cross-repo vocabulary is not wanted now).

   • Workload note: Q2-A is about one feat(spec)!: a page action row's onSuccess is refused beside a runner built-in other than api / script, and beside no executor #23331-sized PR plus an objectui card. Q2-C is a text PR. That is a ≥3× difference, named here as the decision-analysis rule requires; ① still reads A.
   • Confidence gaps:
     • HotCRM was not read by this seat.
     • Third-party apps are not visible.
     • Whether full-width (a second name for default, zero first-party writers) stays in the closed list is left to the executor's measurement.
     • objectui#12195 (the record-page half of isDefault) is open, so today isDefault decides nothing on any page in the console. Q1-A does not depend on it.

   自检:只看①选 Q1 A、Q2 A;②③④ 是否翻转:否。

   After the ruling

   • The card returns to pm:queue for domain:spec. One execution PR (Fixes #23610) carries half 1 and the ruled Q1 and Q2 changes. If both are A and the diff runs large, it may split in two, Part of then Fixes.
   • The skills/objectstack-ui/rules/pages.md rows (home / utility, templates and regions) go in a separate Tier H PR.
   • Under Q2-A, an objectui card retires the stack-the-rest branch for authored pages.
   • Under either A, the repo:hotcrm seat gets a memo for its next pin bump (delete the flag; rename the regions).
   • The contract review is at CONTRACT_REVIEW_TIER: under A this narrows a published accept set (Clause-②: yes, narrowing).
   • This act moves the card to needs-user-decision and clears its assignee.

   os-decision-facets

   • ① 项目长远合理性:Q1-A 让 isDefault 只剩一个含义(记录页默认),落地页留在导航项上(HOME_PAGE_ID_RETIRED 已定的方向);Q2-A 把模板与槽位写进契约,特例减少。B 各自新增一套机制或别名表,C 保留声明与运行时的分叉。
   • ② 实际业务拉动:HotCRM 两条都中(sales_home_page:首页标 isDefault 无效,left_sidebar/right_sidebar 被堆成一列);本仓 showcase 示例的 isDefault 是装饰。错误区域名源自我们自己的 skill。
   • ③ 防 AI 犯错:A 把两处静默无效变成 os validate 时的响亮拒绝并给出正确拼写;C 只在终端用户眼前出错;Q2-B 藏住错误、诱发下一个。
   • ④ 创业阶段不扩散:A 不加能力,只把两处自由面收窄到已在运行的部分;Q1-B 是新功能,Q2-B 是永久维护的别名表;唯一外部生产者已具名,立即退休。
     Prior rulings read: isdefault,landing,homepageid,utility,pagetypeschema,template,region → 13 hits; none rules this (term matches only: ADR-0131 D3, ADR-0006 D3, ADR-0031/0032); governing text read: HOME_PAGE_ID_RETIRED docblock (app.zod.ts), ruling A on spec(page): no stated rule decides between two isDefault record pages for one object, so the renderer cannot honour isDefault without inventing precedence (the spec half of objectui#12195) #23015 (6134056653); thread: none

    Entry check on 6185186322, the domain:spec seat 2 presentation of half 2 plus the repo:hotcrm fold-in 6184870296. These are all present:

    • the speed read with a one-line ask (Q1 A/B/C · Q2 A/B/C);
    • the facts with citations;
    • the options, the recommendation (Q1 A, Q2 A) and the four facets with the token.

    It passes.

    • Both A's narrow what the spec accepts. Q1 refuses a non-record page's isDefault: true; Q2 refuses a region name the chosen template will not place. So they stay in this card's p1 + target:v18 and land inside the major.
    • The consumers are named: HotCRM's sales_home_page, the showcase's showcase_capability_map (isDefault: true on a home page), and skills/objectstack-ui/rules/pages.md, which teaches the unplaced names. Each moves in the execution PRs. The skill edit is its own Tier H PR.
    • Q2 B (the renderer maps names by role) leaves the slot names undeclared. Neither an author nor os validate could then know which names a template places, so it is a consumer-side guess rather than a contract.
    • Half 1 (the promise text) rides the execution PR, as the seat says.

    On the domain:spec seat 2 presentation 6185186322 (Q1 A / Q2 A, fallback C / C) and triage's entry 6185623010.

    Premises re-run in this act, objectstack origin/main c5dd7fce30, objectui origin/main cf430cd10e, hotcrm origin/main 63db83e2da:

    • The promise text stands: page.zod.ts:786-790 (「home is the platform-level landing page … utility is a floating utility panel」) and the enum comments at :807 / :809; the utility print refusal at :1528 says 「a floating panel beside the page a user is on」.
    • isDefault's describe (:1701) is the record-page default, 「outside this rule for a page that is not a record page bound to an object」; HOME_PAGE_ID_RETIRED (app.zod.ts:1351-1363): the landing IS the first navigation item, and a declared landing, if ever wanted, belongs on navigation[].landing, enforce-first.
    • template: z.string().default('default') (:1662) and regions[].name: z.string() (:50) are free strings; objectui's TEMPLATE_REGISTRY (page.tsx:474-480) holds default, full-width, header-sidebar-main, three-column, dashboard — and default and full-width are the SAME component (FullWidthTemplate); the slots are header / sidebar / main / aside / footer, every other region is stacked under main (:285, :384, :417); dashboard grids the rest by design (:455).
    • Producers: the showcase example (examples/app-showcase/src/ui/pages/capability-map.page.ts:44 type: 'home', :46 isDefault: true); HotCRM src/sales/pages/home.page.ts still carries type: 'home', template: 'three-column', regions left_sidebar (:128) and right_sidebar (:276) and isDefault: true (:347). HotCRM's utility producer is gone: hotcrm#2119 (63db83e2, the current tip) retired the Utility Bar page, so no first-party or named external page of type: 'utility' remains. skills/objectstack-ui/rules/pages.md:38-40 still teaches three-column / two-column / single-column and left_sidebar / right_sidebar.
    • packages/spec/liveness/page.json is on origin/main (the type, template, regions and isDefault rows the seat names).
    • Prior rulings (check-prior-rulings --card 23610): 194 hits; the named decisions (ADR-0005 §5/§6, ADR-0023 §5, ADR-0030 §9, ADR-0031 §2/§5, ADR-0032 §4, ADR-0035 §3/§4) are term matches in ADRs about overlays, connectors, notifications, flow nodes, expressions and master-detail; none rules a page template, a region name or a non-record page's isDefault; thread: none. Governing text: the HOME_PAGE_ID_RETIRED docblock; ruling A on spec(page): no stated rule decides between two isDefault record pages for one object, so the renderer cannot honour isDefault without inventing precedence (the spec half of objectui#12195) #23015 (6134056653) for the record-page half.

    Facets: ① agree — Q1-A leaves isDefault one meaning and the landing on the navigation item; Q2-A puts the layout vocabulary where an author and os validate can see it · ② agree — HotCRM hit both, and the wrong names come from our own skill; nobody relies on the flag doing anything · ③ agree — both A's turn a silent no-op into a refusal that carries the correct spelling · ④ agree — both A's narrow a free surface to what runs; no new capability.

    Recommend Q1 A, Q2 A; fallback Q1 C, Q2 C. 口径 for the executor, binding with the letters:

    1. Q1-A: every door (defineStack / os validate, registration, saveMetaItem) refuses isDefault: true on a page defaultRecordPageObject does not place; the refusal names the navigation order and the APP's isDefault for the root landing; the showcase example drops the flag in the same PR (its landing is unchanged: it is first in navigation); a semantic migration entry; no grace window.
    2. Q2-A: template closes to the renderer's registered names, and each template declares its slots in the spec (default: header / sidebar / main / aside / footer; header-sidebar-main: header / sidebar / main; three-column: the five; dashboard: header / footer plus an open grid). A region the chosen template will not place is refused at os validate and save, naming the slots. full-width retires rather than entering the list: it is a second name for default (the same component, zero first-party writers) and the stage keeps no alias; if the executor measures a rendering difference, report the fork, do not keep both quietly.
    3. Half 1 rides the same PR: the docblock and enum comments say what runs (home = a wide region page, the landing is the first navigation item; utility = an ordinary inline page with no floating shell); the utility print refusal's sentence and its pin; content/docs/ui/pages.mdx. The utility enum value stays: it has readers (the print door refuses it, PRINT_PAGE_TYPES at :1462; the page-type width), so it is not an inert declaration; a floating shell slot is NOT built (zero pull after hotcrm#2119) and no card is opened for it. This closes the sub-question triage left open.
    4. The skills/objectstack-ui/rules/pages.md rows go in a separate Tier H PR, as the seat says.
    5. Under Q2-A an objectui card retires the stack-the-rest branch for authored pages; the repo:hotcrm seat gets a memo for its next pin bump (drop the flag; left_sidebar → sidebar, right_sidebar → aside).
    6. Contract review at CONTRACT_REVIEW_TIER (published schema; Clause-②: yes, narrowing). If both A's run large, PR-1 (Part of) carries Q1 and half 1, PR-2 (Fixes) carries Q2.

    Workload: as the card states; Q2-A (one #23331-sized PR + the Tier H row + an objectui card) against Q2-C (a text PR) is the ≥3× difference the rule names; ① still reads A.

    自检：只看①选 Q1 A、Q2 A；②③④ 是否翻转：否。
