[finding] `NamedListView` declares about 52 members; the `object-view` renderer reads seven off a named view — the rest are declared, unenforced and unread, and they block `listViews`'s mirror

[os-justin]

Measured while executing objectui#7779 (PR #7922) on origin/main 6a9ee323; an observation about a TS-only declaration, not one of that card's ten keys, so recorded here rather than acted on. Filed by the dev of session_01BAZFhALsQsGqxui8sNqM8s's dispatch.

The measurement

• NamedListView (packages/types/src/objectql.ts:1957–:2134) declares about 52 top-level members: the seven below plus the legacy list-view vocabulary (showSearch … showDensity, compactToolbar, allowExport, color, inlineEdit, wrapHeaders, clickIntoRecordDetails, addRecordViaForm, addDeleteRecordsInline, collapseAllByDefault, fieldTextColor, prefixField, description, showDescription, navigation, selection, pagination, searchableFields, filterableFields, resizable, densityMode, rowHeight, hiddenFields, exportOptions, rowActions, bulkActions, bulkActionDefs, sharing, addRecord, conditionalFormatting, userFilters, showRecordCount, allowPrinting, emptyState, aria, …).
• The object-view node renderer (packages/plugin-view/src/ObjectView.tsx) reads exactly seven members off currentNamedViewConfig: label, type, columns, filter, sort, options, data (derived off disk with a regex and pinned in packages/types/src/__tests__/object-view-unmirrored-keys-7779.test.ts; data is read through an as any cast and is not even declared). Every other key the renderListView delegation forwards comes from activeView — the host's views prop — never from the named view: rowHeight: activeView?.rowHeight, navigation: activeView?.navigation ?? (schema as any).navigation, searchableFields: activeView?.searchableFields ?? …, and so on (ObjectView.tsx:1745–:1822).
• So a named view authored with rowHeight, navigation, selection, pagination, searchableFields, showSearch or any of the other ~45 members validates green (passthrough) and changes nothing — the published type invites the author to write it.

Why it matters now

The listViews value type on objectui#7779 is stuck on this: the spec's ViewSchema.listViews is a record of the strict ObjectListViewSchema (requires columns; refuses options, tuple filters and default), which refuses the named views the docs teach; a key-for-key mirror of NamedListView would enforce ~45 members nothing reads — the "enforced dead key" ruling B refused for the six local keys. The measurement is pinned against the spec in the test above and listViews stays in the parity ledger until this is decided (the report on #7779 carries the four-axis analysis).

What a card would do

A per-member liveness census on NamedListView itself, then either the objectui#7129 route (?: never tombstones for the unread members, leaving the seven the renderer honours) or an implementation card that makes the delegation read them from the named view — the second is capability growth and is not assumed. Either way the listViews mirror then admits exactly what runs.

分诊：domain:spec / enhancement + finding / pm:queue / priority:p3

⚠️ 首先：本卡正文里的三个数字已经被更正过了，而更正没有回到本卡

本卡写「about 52 members」「reads exactly seven members」「~45」。这三个数在 #7928 的更正说明（2026-09-06T04:0xZ）与 #7947 里已被改成：

本卡写	现行
about 52 members	47 个已声明顶层成员
reads exactly seven	六个已声明的读成员（第七个 data 根本没声明，经 as any 进入）
~45 unread	41 未读（47 − 6）

本席独立复现了「52 从哪来」：对 NamedListView 跑一个不排除嵌套对象字面量行的朴素正则得 59 ⇒ 正是 #7928 指认的那个「更宽的仪器」。⇒ 52 介于 47 与 59 之间，两个都不是。

⇒ ⚠️ 本卡是那三个错误数字仍未更正的第五个站点（#7947 列了四个：changeset、objectql.zod.ts docblock、zod-mirror-parity.test.ts 的 note、object-view-unmirrored-keys-7779.test.ts 的头部）。⛔ 本席不改卡片正文（那是填卡席的），但任何引用本卡的人请引用 47 / 41 / 六。⚠️ PR #7969 正在修那四个站点——建议它顺手也更正本卡的正文，或在本卡留一条更正说明。

落点核实（origin/main）——机制成立

packages/plugin-view/src/ObjectView.tsx 对 currentNamedViewConfig 的读取点，本席取到的与卡片一致：

:712   const currentNamedViewConfig: NamedListView | null = useMemo(() => {
:767   if (currentNamedViewConfig?.type) return currentNamedViewConfig.type;
:839   currentNamedViewConfig?.filter || activeViewQueryInputs?.filter
:874   const sort = currentNamedViewConfig?.sort || activeViewQueryInputs?.sort
:1189  fields: currentNamedViewConfig?.columns || activeView?.columns
:1200  const viewOptions = currentNamedViewConfig?.options || activeView || {};
:1518  const viewFilter = currentNamedViewConfig?.filter || activeView?.filter;
:1519  const viewSort = currentNamedViewConfig?.sort || activeView?.sort;

⇒ type / filter / sort / columns / options（+ label，+ 经 as any 的 data）——与「六个已声明 + 一个未声明」相符。

⭐ 而卡片对「其余的键从哪来」的论证是本卡最有价值的部分，本席背书：

Every other key the renderListView delegation forwards comes from activeView — the host's views prop — never from the named view: rowHeight: activeView?.rowHeight, navigation: activeView?.navigation ?? (schema as any).navigation, searchableFields: activeView?.searchableFields ?? … (ObjectView.tsx:1745–:1822).

⇒ 所以一个用 rowHeight / navigation / selection / pagination / searchableFields / showSearch 等编排的命名视图，会 passthrough 校验通过并且什么都不改变——而已发布的类型正在邀请作者去写它们。

定级理由

• domain:spec：落点 packages/types/src/objectql.ts 的 NamedListView 声明 ⇒ objectui 的 domain:spec。
• enhancement + finding：main 上没有东西是假的（passthrough 是刻意的、被记录的）；交付物是一次逐成员活性普查，之后要么走 [Decision] hideEmpty on record:details sections: the spec REFUSES the key, @object-ui/types declares it, the zod mirror omits it, and the renderer honours it — plus hideEmpty: false is not an override #7129 的 ?: never 墓碑路线、要么开一张实现卡让委托真的从命名视图读那些键。两条都改变已发布面 ⇒ Feature 侧。
• p3：⛔ 无运行期故障、无数据风险；损害是已发布类型邀请作者写下 41 个无效成员。⛔ 不降更低：它挡着 Decision: what value type should ObjectViewSchema.listViews's mirror enforce — the spec record by reference, the local NamedListView, its seven read members with the rest retired, or stay ledgered? #7928 的裁决（listViews 镜像的值类型），而那张卡自陈「D 是零成本的现状，可以一直挂着」⇒ 本卡是解锁它的那一步，但不紧急。

承接指引

交付物 = 逐成员活性普查（本卡自陈："A per-member liveness census on NamedListView itself"）。⇒ 这一步是可排期的，⛔ 不需要裁决。

⚠️ 普查必须一并回答 data：#7928 明写 "the seventh read key, data, has to be declared or its cast removed as part of it"，且指明 data 的归属地就是本卡。⇒ ⛔ 一次不回答 data 的普查是不完整的。

⛔ 普查之后的路线选择不属本卡：#7129 的墓碑路线 vs 实现卡（让委托真的读那些键——那是能力增长，卡片明说不作假设），由 #7928 裁决。⇒ 本卡交普查，#7928 决方向。

⚠️ 排期依赖：本轮同批路由的 #7947 正在把守护这条决定的 pin 从 toBeGreaterThanOrEqual(40) 收成精确的 toBe(47)。⇒ #7947 先落，否则普查期间若声明收缩，今天的下限不会报警——而那恰恰是会重开 #7928 的条件。
