console mobile (≤ 640 px): list as card rows with view chips and a FAB, the record page with a compact header, sticky tabs and a bottom action bar, related records pushed as full pages with a path row and back — the record is always a page on a phone

epic:#26676#1 · zhuangjianguo · session_637faf9ef5c84d1bab00007c255c1861

Part of the record-page epic #26676 — the v4 record page on a phone. Target rewritten in full on 2026-10-31 against the canvas-60 RecordMobile board, on the maintainer's ruling (2026-10-31, verbatim): 「按画布 60 的 RecordMobile 板重写 #27058 的 Target，保持 pm:queue」. Design: evidence branch claude/record-page-v2-evidence-20261027b @ a7825499aa, folder docs/design/record-page-v2-2026-10-27/v4/ — RecordMobile.dc.html (390 px, three frames: the list · the record page · one level down) and notes.md n46–n51 (n47 the top bar, n48 the stack below 760 px, n50 the tab row, n51 the HotCRM audit). Read with git show a7825499aa:<path>; never merge that branch. The board was drawn before n47 / n50 and is read through them: its view-tab chip row is superseded by #27594 (the title is the view switcher), its 「‹ Mira Costa ↑ ↓ ⋯」 line is the v4 top bar, and its record body is the < 760 px stack of #27524 item 6.

The phone is not a separate design. It is the v4 record (#27524) in a container narrower than 760 px, with three things only a phone adds: the record is always a page, the business actions sit in a bottom bar, and a related record is pushed as a page with a path row. This card therefore runs after #27524 ③ (the tab row, items 8–9) and ④ (the top bar, item 7) are on main: the components it extends do not exist before that, and the seats should not claim it until both are merged. It stays pm:queue on the maintainer's word; no pm:blocked.

Source (origin/main `a0f865491d`, 2026-10-31, measured)

List on a phone (viewport < 768, useIsMobile): ObjectGrid draws card rows titled by the declared name field (On a phone, a grouped list (grouping) keeps its desktop grid — titles cut mid-word, other columns behind the pinned Actions column — while the same console turns a plain list into cards #26896 / objectui#13150); the list page header is hidden below sm (ObjectView.tsx 「Mobile: hide the entire PageHeader」); the view switcher is a 「 ▾」 dropdown the AppHeader draws from MobileViewSwitcherContext — the Console lists: the list-view switcher becomes a dropdown on the list title (search, pinned default, recent), the flat view-tab row retires, and a starred view appears in the sidebar's 收藏 group #27594 title switcher (objectViewTitleSwitcher.tsx) is desktop-only and 「ignores this context entirely」; 新建 is the FAB mobile-fab-create (sm:hidden fixed right-4 bottom-36). No bottom nav exists in app-shell/src/layout (the FAB comment names one; none is drawn).
Record on a phone: the console calls deriveRecordSurface(objectDef) with no viewport option (console/AppContent.tsx), so the spec rule if (opts.viewport === 'mobile') return 'page' (packages/spec/src/data/record-surface.ts) never fires. The record opens in the ObjectView pane (Record drawer v4: a bounded peek over the list — md cap instead of the field-count bucket, no dim overlay, the list stays readable and clickable, ⤢ maximizes in place at the same URL; the full page is reached only from the row ↗ and the header ⋯ #27545): a content area under RECORD_SPLIT_MIN_CONTENT_PX (1000) falls back to the drawer face, and below sm the drawer is w-screen max-w-none — a full-screen sheet over the list, with the pane's bar on top. recordPageTierFor answers tabs for any embedded page and for any width under 760, so the body is the 详情 / 相关 N / 时间线 segmented tier (the Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 ② stack, PR feat(plugin-detail)!: one record page laid out by its own width; 动态 is the right column's first panel #28116, is not merged yet). A related row opens one level down in the drawer stack (console record drawer v2: the bar is ↑ ↓ · ⤢ · ✕ (no object name, no counter); a related row or a lookup opens its record in place with a trail, ← / Esc go back one level; ⤢ carries the trail into the page; on the record page a related row opens a drawer over the page #26679), the bar's ← path.
Related lists on a phone render as object-gallery cards (RelatedList.tsx: 「Mobile: render grid/table data as a card gallery」), title field + the next three columns.
Full page (an object that declares page, or ↗ / ⋯ from the pane): a crumb row above the body with the ‹ origin link read from the ?from= trail (decodeRecordTrail, RecordDetailView.tsx 「the top bar draws no record crumb (objectui#12461)」), PageHeaderActions in the header, actions wrapping.

Target (canvas 60 `RecordMobile`; #27524 items 6–12 and #27594 apply unchanged, this card only says what the phone adds)

The record is always a page on a phone. The console passes viewport: 'mobile' to deriveRecordSurface when useIsMobile() is true, so the spec's own rule answers page: a list row tap navigates to the record route (the ?from= trail carries the list context), the pane (split / drawer) is never mounted, and the reader's recordOpen preference (split / drawer / page) and the ⊟ switch do not apply. No metadata key; the spec already declares the rule and the console enforces it.
List (container < 760 px): the card rows stay (declared name field as the title, one subtitle line from the first two shown columns, one status chip); the list title is the Console lists: the list-view switcher becomes a dropdown on the list title (search, pinned default, recent), the flat view-tab row retires, and a starred view appears in the sidebar's 收藏 group #27594 switcher 「 ▾ · N」 on the phone too — the page header's title row is drawn below sm, with the filter / sort / display icons on its right, and the AppHeader's MobileViewSwitcherContext dropdown retires (one switcher, as Console lists: the list-view switcher becomes a dropdown on the list title (search, pinned default, recent), the flat view-tab row retires, and a starred view appears in the sidebar's 收藏 group #27594 item 5 says: 「nothing else is special-cased」); the filter / sort chips keep one row with the count at the right; 新建 stays the FAB; the Display menu drops the layout row on the phone.
Top bar (Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 item 7, compressed to 390 px): left, one link 「‹ 」 — the breadcrumb's object half; the record name is the header title directly below and is not repeated. Right: the counter 「3 / 21」 and ↓ ↑, drawn only when the page arrived with a ?from= list trail. No ⊟ (the stack has no right column), no ⤢ / ⤡, no ✕.
Header: avatar / initials, the name, the object chip; a subtitle line from the first two declared highlightFields that are text (the board: 「Atlas Construction · Director of Sales」); then the remaining declared highlights minus the name in two columns, at most four on the phone (Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 item 12's rule, narrowed by width; the rest are in the sections anyway); the stage path compressed to one bar with its labels (「✓ 新建已联系已确认已转化」). No header action row on the phone (item 6 below owns the actions).
Tab row and enlarged state (Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 items 8–9, unchanged): 「概览 · 动态 N · N · +N ▾」 at the bottom edge of the header block, the visible count computed from the 390 px row (概览 and at least one more always visible, the active tab always visible); a tab's enlarged state is the active tab, URL ?related=object.field, and on the phone it fills the body with the child object's card rows (the related list's phone face), not a wide table; Esc / 概览 returns.
Body = the < 760 px stack (Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 item 6, unchanged): the details sections (frameless, fields in two columns, 「显示 N 个空字段」 per section, the authored collapsed groups folded to one line 「地址 · 转化 · 附加信息 3 个空分区」), then the 动态 panel (one-line composer, the newest 3, 「查看全部 N 条 →」 opens the 动态 tab), then the related panels in record.related.arrangement order (compact rows, count chip, header tap = tab), the empty panels folded into 「还有 N 个空关联 · … · 展开」. The arrangement's order / hidden apply on the phone; nothing else is remembered.
Bottom action bar: the primary action, one secondary and ⋯ (the page's declared order, the same cap as the desktop header row: 1 + 2 + ⋯, the second secondary folding into ⋯ at 390 px) fixed at the bottom above the safe area (the board: 「转化线索记录通话 ⋯」 on the lead, 「标记完成改期 ⋯」 on the task); the body scrolls under it (scroll-pb for the bar's height); the FAB is not drawn on a record page.
One level down: a related row or a lookup opens the record as a page pushed over the current one (route navigation with the ?from= trail extended; no drawer stack on a phone); a path row under the top bar 「线索 Mira Costa › 任务」 is the trail, each segment a link; 「‹」 returns to the parent and restores its scroll position (the related panel it came from); ↓ ↑ step through the same sibling set the desktop stack steps through — the parent's related rows for that list. The board's note, verbatim: 「手机上没有抽屉：关联记录整页推入，‹ 返回到线索并停在原滚动位置（关联面板处）；↑↓ 在同一层的兄弟（Mira 的 2 条任务）里翻；路径行就是桌面抽屉里的 ← 路径。」
No new metadata key; no new reader preference; ⛔ packages/spec/** (the viewport option already exists); ⛔ the pane's split / overlay / maximize mechanics (Record drawer v4: a bounded peek over the list — md cap instead of the field-count bucket, no dim overlay, the list stays readable and clickable, ⤢ maximizes in place at the same URL; the full page is reached only from the row ↗ and the header ⋯ #27545) — the phone never mounts them.

Rulings (maintainer, chat in the filing session, 2026-10-28 — verbatim, not re-decidable here)

Record-page model (2026-10-27): 「1. 一个对象一个默认打开方式：默认抽屉（带展开整页），page 只给显式声明的对象，modal 退役，split / popover 变成用户个人偏好；抽屉和整页是同一张页在两个宽度。」
On the resident timeline column: 「时间线是不是太突出了，这个只适合部分对象吧？适合做所有业务对象的默认布局吗」 and then 「时间线是否显示，是否可以切换，比如当前版本的 Claude code，顶部有很多切换图标」 — the column's presence is a per-user toggle with an object-derived default, never metadata.
On the related column's cost: 「关联都放在右侧，记录打开时是不是会很慢，因为需要加载所有的关联子表。」 — the related column loads counts first, rows on demand, and never blocks the details.
On mobile: 「还要考虑手机端的效果。」
On the definition surfaces: the PM's keep / narrow / retire table was put to the maintainer (keep object roles, relationship flags, six slotted slots and kind: full; retire the tabs slot and the dead BuildPageOptions hints; fold the quick-look path into the one record page) and approved with the instruction in the footer.

Premise: does not hold as written. Not claimed. For epic:#26676#1.

The domain:ui seats read this card for dispatch 2026-10-30T03:00Z. Its Target predates the v4 cards now in flight and contradicts two of them:

Target 2 asks for "sticky tabs 详情 / 时间线 / 关联 (the tabbed tier)" on the phone. Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 item 6 (the maintainer's v4 ruling) retires the tabbed tier: below 760 px the record is one column, and "the embedded record and the phone use the same rule". The tab row (item 8) and the top bar (item 7) are on every face, phone included, and 时间线 becomes 动态, a panel.
Target 1 asks for "the view tabs become a horizontally scrolling chip row". Console lists: the list-view switcher becomes a dropdown on the list title (search, pinned default, recent), the flat view-tab row retires, and a starred view appears in the sidebar's 收藏 group #27594 retires the view tab row in favour of the title dropdown, the narrow list included.

The v4 board folder carries its own RecordMobile.dc.html (at a7825499aa), so the Target should be rewritten against canvas 60 before anyone builds it. #27524, #27545 and #27594 are claimed by domain:ui seat 2 and touch the same header and tab components, so this card also runs after they land.

Asked: a Target rewrite by the epic PM against the v4 board. The card stays in pm:queue; the seats will not claim it until it is rewritten. #27059 (skills/docs for the record page) likewise waits for v4 to land, since it documents what v4 ships.

Target rewritten against canvas 60 · 2026-10-31 · pm:queue kept, no label or assignee change.

The maintainer, 2026-10-31, verbatim: 「按画布 60 的 RecordMobile 板重写 #27058 的 Target，保持 pm:queue」 — answering domain:ui seat 3's reading of 2026-10-30 (comment 6512993303) that the old Target 1 (a view-tab chip row) and Target 2 (sticky 详情 / 时间线 / 关联 tabs, the tabbed tier) contradicted #27594 and #27524 item 6.

What changed in the body above:

Source re-measured on origin/main a0f865491d: the phone list is already card rows + an AppHeader 「 ▾」 dropdown + the FAB; the record opens in the pane's full-screen drawer face, not as a page, because the console calls deriveRecordSurface without viewport: 'mobile' and the spec's phone → page rule never fires; the body is still the tabbed tier until Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 ② merges.
Target is now the v4 record in a < 760 px container (Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 items 6–12 and Console lists: the list-view switcher becomes a dropdown on the list title (search, pinned default, recent), the flat view-tab row retires, and a starred view appears in the sidebar's 收藏 group #27594 unchanged) plus what only a phone adds: the record is always a page (the console passes the spec's own viewport: 'mobile'), the Console lists: the list-view switcher becomes a dropdown on the list title (search, pinned default, recent), the flat view-tab row retires, and a starred view appears in the sidebar's 收藏 group #27594 title switcher replaces the MobileViewSwitcherContext dropdown, the top bar compresses to 「‹ 」 + counter / ↓ ↑, highlights in two columns (max 4), the business actions in a bottom bar (1 + 1 + ⋯), the enlarged tab draws the child object's card rows, and a related record is pushed as a page with the path row (the board's own note is quoted). The board's chip row and its 「‹ Mira Costa ↑ ↓ ⋯」 line are read through n47 / n50, as the body says.
Ordering: runs after Record page v4: same-shaped related panels with no collapse, a persistent tab row under the header (the enlarged state is the active tab), Activity as the first panel and a tab, one top bar on every face, tiers by container width #27524 ③ (tab row) and ④ (top bar) are on main; the seats should not claim it before. Not pm:blocked — the maintainer's word is pm:queue.
File surface / Acceptance point at today's files (objectViewPageHeader.tsx, AppHeader.tsx, MobileViewSwitcherContext.tsx, RecordDetailView.tsx, the shared stack tier and the ③ tab-row component), screenshots on examples/app-crm at 390 × 844.
The Rulings section and the filing footer are kept verbatim; a second footer line records this rewrite.

Two readings in the new Target are the seat's, not the maintainer's, and the maintainer may veto either: the phone top bar's left end as one link 「‹ 」 (the record name is the title below), and the bottom bar's cap of one secondary action at 390 px.

Landed · 2026-10-31T23:00Z · PR #28477 (seat ACCEPT 6550121631 and TIER_DEFAULT contract review PASS 6549952200, pinned to af3acee1; preview gate vs RecordMobile in the ACCEPT)

Probe	Reading
PR #28477	merged 2026-10-31T22:59:16Z through the merge queue as `ee29ac39e8`
This card	closed `completed` by the PR's `Fixes` line; `pm:dispatched` removed in this landing

Below 768 px the record is always a page, with one view switcher on the list, the phone top bar, the compact header, the bottom action bar, and related records pushed as pages with a path row. Follow-ups from the ACCEPT (item 6), each its own card: #28483 (a phone record page draws the app bar above the record's top bar, and the app bar repeats the record name; where the app menu, search, notifications and account go is a product call, put to the maintainer there); #28484 (the phone list's card row face: name, one subtitle line, one status chip, in plugin-grid). The counter's group scope stays #28461.
