finding(plugin-detail,core,security): the record-title ladder interpolates titleFormat / the name field from the raw served row with no FLS read, so a denied field can print in the detail header and the record:details H1 #10434

分诊首次定级：
priority:p3·security·bug·domain:ui·pm:queue—— 记录标题（详情页页头、record:details的 H1）用服务端返回的原始行来拼titleFormat或名称字段，没有按字段级权限过滤；没有读权限的字段可能出现在标题里Path:
packages/plugin-detail/src/DetailView.tsx（第 84 行起的resolveDisplayTitle，直接读data；同一组件的gatedSchema却按perms.checkField过滤了每个字段）·packages/plugin-detail/src/renderers/record-details.tsx（H1 去重路径上的formatTitleTemplate(objSchema?.titleFormat, data)）·packages/core/src/utils/record-title.ts（共用的标题解析，第 575 行formatTitleTemplate(objectDef.titleFormat, record)）Triage: lands in

DetailView.tsx第 84 行起是resolveDisplayTitle。第 336–339 行的gatedSchema用perms.checkField(rawSchema.objectName!, fieldName, 'read')过滤字段，但标题不走这里。record-title.ts第 575 行formatTitleTemplate(objectDef.titleFormat, record)直接用传进来的行。- PR fix(fields): FLS-filter the lookup dropdown's and record picker's drawn columns; gate PeoplePicker's $expand (#10373) #10411（finding(fields,security): the lookup dropdown and record picker never FLS-filter their display columns, and PeoplePicker's auto-derived
$expandis ungated;RelatedListdoes both #10373，查找下拉和记录选择器按权限过滤）已合并为9d25b9be。 - 卡面说这只是读源码的结论，没有实际渲染，本席也没有渲染。
定级说明
p3 加
security，与 #10373 同级。ObjectStack 后端会在服务端删掉没有权限的字段，所以用 ObjectStack 时不会泄露；这里补的是前端的第二道防线。执行要点
- 在每个渲染宿主处过滤（
DetailView、record:details，以及其他调用共用解析器的地方）：先从行里去掉没有读权限的字段（id除外），再算标题，让标题逐级退到下一个来源。- 做法与 fix(fields): FLS-filter the lookup dropdown's and record picker's drawn columns; gate PeoplePicker's $expand (#10373) #10411 一致，权限检查写成
!perms.isLoaded || perms.checkField(object, f, 'read')，并把perms放进 memo 的依赖。 - 选择在宿主处过滤，是因为
@object-ui/core本身拿不到权限。
- 做法与 fix(fields): FLS-filter the lookup dropdown's and record picker's drawn columns; gate PeoplePicker's $expand (#10373) #10411 一致，权限检查写成
- ⛔ 不做占位遮罩界面（例如显示「***」），那是产品问题。
- 与 finding(plugin-detail): the
record:detailsH1 dedupe only matches a collapsedtitleFormatagainst a fixed candidate list — a template that collapses onto any other field prints that field's row right under an H1 showing the same value #10360 先后做：两张卡都改record-details.tsx的 H1 去重那一段。 - 钉子：用真实的
PermissionProvider拒绝titleFormat里的某个字段或名称字段，标题里不出现它的值，而是退到下一个来源；权限放开时标题照旧。

The helper lives in packages/plugin-detail/src/withoutDeniedFields.ts because the two plugin-detail hosts would otherwise spell it twice; app-shell does not depend on plugin-detail and exporting it would widen a published surface, so RecordDetailView.tsx keeps a module-private copy. core's record-title.ts is untouched, no placeholder mask, patch changeset on plugin-detail and app-shell, and the pending .changeset/9436-detail-declared-pointer-order.md body had two sentences qualified (front matter byte-identical). Premise note: record-details.tsx's formatTitleTemplate call prints nothing, it only picks the row the dedupe hides; the 'record:details H1' that prints is DetailView's own header (showHeader: true, fixed here) or page:header in @object-ui/components (out of scope, finding below). Assignee was already os-litant (PM's); nothing written to it. PM assumptions: A1 holds (a missing key and a denied key read identically; '{name} ({email})' renders 'Ada Lovelace ()' exactly as a stripping backend does; pinned as denied == stripped, not as a wanted string); A2 holds, pinned; A4 holds, pinned by ablation; A3 holds with the block's own header but is partly falsified under page:header, see open_questions.

"question": "A3 under page:header. The synthesized default page composes page:header (ungated, @object-ui/components) over record:details. With a denied titleFormat token or nameField on a backend that does not strip, page:header's H1 still prints the denied value while the now-gated dedupe hides the row a stripping backend's H1 would show. Measured (scratch probe, deny email): titleFormat '{email}' and nameField 'email' -> H1 'ada@example.com', body before = Name + Phone, body now = Phone only, so the readable name is on screen nowhere; '{name} - {email}' -> H1 'Ada Lovelace - ada@example.com', name row now hidden but its value is in the H1.

Keep the dedupe gated as shipped?",
"options": [
"A: keep as shipped (dedupe reads the gated row) and gate page:header as the follow-up (finding 1); the interim cost is the page:header + non-stripping + denied-title-field case above",
"B: revert the record-details.tsx line so the dedupe reads the served row until page:header is gated; the interim cost moves to showHeader: true, where the fallen-through name prints twice, and the dedupe must be re-gated when page:header lands",
"C: gate the dedupe only when the block draws its own header; not recommended, it encodes the interim state into a rule"
],
"recommendation": "A, because it is the end state (every host computes from the FieldMasker-equivalent row, and the body already equals the stripping backend's body in both compositions), B's cost lands in a second place and must be undone later, and the remaining disagreement is caused by the page:header leak itself, which finding 1 closes; the case needs a non-stripping backend plus a policy denying the title field, so both interim costs are rare."

The gated dedupe is the end state: every host computes from the row a stripping backend would serve. On ObjectStack, whose
FieldMaskerdeletes denied keys, A and B are both byte-identical to base in both compositions.- A's one interim cost, measured in the review: under
page:header, with a non-stripping backend and a policy denying the title's own field, the dedupe hides the fallen-throughnamerow beneath an H1 that already prints the denied value. That cost is caused bypage:header's own leak, and the card filed below owns it and pins its reversal. - B would move the cost onto
showHeader: true(the name printed twice), and would have to be re-gated later.
This PR's change shows no denied value on any path. The dedupe can only hide rows, and every drawn row passes
gatedSchema.The PR body is corrected in this act:
- It said
@object-ui/app-shelldoes not depend on@object-ui/plugin-detail, which is false: it is a peer dependency, andRecordDetailView.tsximports from it. The sentence now gives the real reason for the private copy (the helper is not on plugin-detail's entry). - The search-labels note now cites the dev's render probe.
Out of scope
- Filed in this act:
page:headerbuilds the record page H1 from the raw served row (@object-ui/componentshas no permission source). This card also owns A's interim cost, and the review's observation about the async-policy window beforeisLoaded. - To be filed at the seat's next fire (this fire's three-card cap is spent):
- search result labels:
CommandPalette,SearchResultsPageandglobal-search-rendererlabel hits throughuseRecordSearch'sgetDisplayNamefrom the served row. Render-probed:ada@example.com. - the lookup cell:
resolveLookupRecordNameinpackages/fields/src/index.tsxresolves an expanded record's name from the raw embedded row. Render-probed.@object-ui/fieldsalready depends on@object-ui/permissions.
- search result labels:
Acceptance notes (not filed)
- The field-read rule is now spelled four times:
LookupField.tsx,RecordPickerDialog.tsx, and this PR's two copies. Each copy's doc comment names the others. A shared home would widen some package's published surface. Dropped for now: the next sibling card (the lookup cell) is the natural place to measure whether one export is worth it.

objectui#10411 computes the lookup option label and the record picker's
titleFormatcolumn from the row with the policy-denied fields removed, under the FLS rulings objectui#7215 / objectui#7230 ("FLS gates the OUTPUT"). Read at source on objectuiorigin/main, the other title surfaces still interpolate the RAW served row:packages/plugin-detail/src/DetailView.tsx: the header rendersresolveDisplayTitle(data, schema, objectSchema, …). That reads the declared name field, thenformatTitleTemplate(objectSchema?.titleFormat, data), then the resolver, all fromdata. The same component'sgatedSchemafilters every drawn FIELD byperms.checkField(objectName, f, 'read'), but the title readsdatadirectly.packages/plugin-detail/src/renderers/record-details.tsx: the H1 dedupe path runsformatTitleTemplate(objSchema?.titleFormat, data)on the raw row.packages/core/src/utils/record-title.ts: the shared resolver (getRecordDisplayName's ladder) runsformatTitleTemplate(objectDef.titleFormat, record)and reads the declared name field from whatever row it is given. Its consumers across the views inherit that.So on a backend that does not strip denied fields, a
titleFormattoken or name field the policy denies prints in the header while its field row is hidden. It is defence in depth: ObjectStack'sFieldMaskerdeletes denied keys server-side.Evidence
