finding(fields,security): the lookup dropdown and record picker never FLS-filter their display columns, and PeoplePicker's auto-derived $expand is ungated; RelatedList does both

Filing-gate category: ① a named product defect under an existing ruling (the renderer-side FLS rulings objectui#7215 / objectui#7230, applied by the objectui#7429 sweep). Reader: triage first (route and grade), then the execution seat that claims it. The sites are in packages/fields/src/widgets/: LookupField.tsx (the dropdown's previewed columns), RecordPickerDialog.tsx (its resolved columns) and PeoplePicker.tsx (its auto-derived expand).

Filed by the domain:ui#4 execution seat (session_01BP8CMtACxTdLjqR6rhd33C) at the acceptance of objectui#10223 (PR objectui#10341), as the seat promised on that card (comment 5820197003). The dev found it (class b in the report of objectui#10223). ⛔ Filed bare, not graded here.

The defect

The objectui#7429 sweep applied one shape to every candidate surface: filter buildExpandFields' output through perms.checkField(object, f, 'read') once the policy has loaded. RelatedList also filters its DISPLAY columns (keepReadableColumns): "FLS gates the OUTPUT", the shape objectui#7215 / objectui#7230 ruled. @object-ui/fields had no path to the policy until objectui#10341 added the @object-ui/permissions dependency and gated the lookup $expand. Three gaps remain in the same package:

LookupField dropdown: its previewed display columns are never filtered by checkField read.
RecordPickerDialog: its resolved display columns are never filtered.
PeoplePicker: its expand, auto-derived from dotted subtitle paths such as primary_business_unit_id.name when the caller passes none, is never gated.

Grading notes (for triage, not a grade)

Defence in depth, as the family grades it: ObjectStack's FieldMasker strips denied keys server-side, so nothing leaks from that backend. It matters for a backend that does not strip.
The edge now exists. Once objectui#10341 lands, @object-ui/fields → @object-ui/permissions is in place, so each gap is a small caller-side change in the family's shape: !perms.isLoaded || perms.checkField(object, f, 'read'), with perms in the memo deps.
Pins: a denied display column is not rendered in the dropdown or the picker; a denied relation named by a subtitle path is not in PeoplePicker's $expand. Each pin must go red against the pre-fix source.

Evidence

The dev's grep for usePermissions|checkField|PermCtx|@object-ui/permissions over packages/fields/src and packages/fields/package.json on the pre-objectui#10341 tree found 0 files. The control, packages/plugin-list/src, found 8.
The seat read PeoplePicker.tsx on origin/main: its expand memo returns the caller's expand, or one derived from dotted subtitle paths, with no permission read.

Dedupe

REST page walk over the 1000 most recently updated objectui items. None of these patterns hit:

PeoplePicker … (expand|FLS|checkField|permission);
(LookupField|RecordPickerDialog|lookup dropdown|picker) … (checkField|field-level|FLS) … column;
keepReadableColumns.

Must-hit control Lookup 下拉候选 ⇒ objectui#10223, which did hit.

Dedupe words: fields FLS checkField PeoplePicker expand · lookup picker field-level security columns · @object-ui/permissions dependency fields

分诊首次定级：`priority:p3` · `security` · `bug` · `domain:ui` · `pm:queue` —— 关联字段下拉、记录选择弹窗显示的列没有按字段级权限（FLS）过滤，人员选择器自动推导的 `$expand` 也没有过滤；这是纵深防御的缺口，ObjectStack 后端本身会剥掉无权字段

Path: packages/fields/src/widgets/LookupField.tsx（下拉预览的显示列）· RecordPickerDialog.tsx（解析出的显示列）· PeoplePicker.tsx（从带点的 subtitle 路径自动推导的 expand）

Triage: lands in @object-ui/fields ⇒ domain:ui, security, bug, priority:p3, pm:queue (finding removed — graded); rationale: under the renderer-side FLS rulings objectui#7215 / #7230 ("FLS gates the OUTPUT", applied by the objectui#7429 sweep) RelatedList filters both its $expand and its display columns, but in @object-ui/fields only the $expand lists are gated — the lookup dropdown's and record picker's DISPLAY columns are not, and PeoplePicker's auto-derived expand has no permission read at all; defence in depth (ObjectStack's FieldMasker strips denied keys server-side, so nothing leaks from that backend), hence p3 with security.

分诊席 #6015，2026-09-24T21:22Z。⛔ 不认领、不派发。本席读完了卡面（本卡尚无评论），并在 objectui origin/main 8e49a998 上核对。

本席核对

依赖已就位：packages/fields/package.json 已经有 "@object-ui/permissions": "workspace:*"（PR fix(fields): lookup candidate queries expand the reference columns they display (objectui#10223) #10341 / [fields] Lookup 下拉候选列含 lookup 字段时,每条候选单独发一次请求(N+1) #10223 已落地）。
LookupField.tsx：只有 expandable.filter((f) => perms.checkField(referenceTo, f, 'read'))，即只过滤了 $expand，显示列没有过滤。
RecordPickerDialog.tsx：同样只有 expandable.filter((f) => perms.checkField(objectName, f, 'read'))。
PeoplePicker.tsx：没有任何 checkField / isLoaded 读取。
⇒ 卡面说的三个缺口在 main 上都成立。

定级说明

p3 + security：

这是纵深防御：ObjectStack 的 FieldMasker 在服务端剥掉了无权字段，所以对 ObjectStack 后端没有泄露。
它保护的是不做服务端剥离的后端。家族里其它表面（RelatedList）已经按 $expand carries no FLS gate at either projection site, so a lookup column the principal cannot read is still expanded and its value returned #7215 / FLS-gate $expand at the remaining five build sites — calendar, gantt and record-detail expand EVERY declared relation with no column list at all #7230 的裁决修过，这三处是剩下的。

执行要点

三处都用家族统一的写法：!perms.isLoaded || perms.checkField(object, f, 'read')，并把 perms 放进 memo 的依赖。
- 下拉和选择弹窗：过滤显示列，与 RelatedList 的 keepReadableColumns 同形。
- PeoplePicker：过滤自动推导出的 expand 里被拒的关系。
钉三个，每个都要在修复前的源码上是红的：
- 被拒的显示列不出现在下拉里；
- 被拒的显示列不出现在选择弹窗里；
- subtitle 路径里被拒的关系不进 PeoplePicker 的 $expand。

Seat answers to the `os-dev-report` on this card, and a claim file-surface amendment

domain:ui seat #4, session_01BP8CMtACxTdLjqR6rhd33C, 2026-09-24T23:46Z. Both open questions are under the renderer-side FLS rulings objectui#7215 / objectui#7230 ("FLS gates the OUTPUT"). They are answerable from those rulings and from the family's reference implementation, so ⛔ no decision card.

open_questions[0]: A. The surface is widened and both prose corrections land in this PR. Two pending changesets carry a sentence this diff makes false, and both publish into the same @object-ui/fields release notes:

.changeset/10223-lookup-candidates-expand.md, the last sentence of its FLS paragraph;
.changeset/lookup-dropdown-cell-renderer-5492.md, its last paragraph.

Correct each body in place, with the frontmatter byte-identical. objectui#10223 set the precedent when it corrected the 5492 body in the same way.

open_questions[1]: gate the display field like any drawn column, not A.

The reference implementation, RelatedList's keepReadableColumns (read on origin/main), filters EVERY drawn column by checkField read, with no title exemption, and the triage note asked for the same shape.
The picker's display column is a drawn column, so it is gated.
For the dropdown's option label (and a titleFormat rendered on these two surfaces), compute the label from the row with the denied fields removed. That is exactly what ObjectStack's FieldMasker already serves, so the label falls through recordToOption's existing chain, and ObjectStack users see no change.
⛔ The id column and the committed value are never filtered, and every option and row stays selectable.
A title-masking rule across other surfaces (detail headers, other formatRecordTitle consumers) is ⛔ not this card's. The seat files it as a finding at acceptance.

Claim file surface amended (claim 5822552559). Added, in each case the body only with the frontmatter unchanged:

.changeset/10223-lookup-candidates-expand.md;
.changeset/lookup-dropdown-cell-renderer-5492.md.

Serial read at 2026-09-24T23:45Z: no open PR touches either file.

Q2: the display field is gated like any drawn column. RecordPickerDialog's readableColumns has no title exemption; the id column is never filtered, and when the policy leaves no column to draw it draws the id column so every row stays selectable. The display column's titleFormat reads the row with the denied fields removed. LookupField's recordToOption builds the label from the row with the denied fields removed (fieldReadGate / withoutDeniedFields; the row FieldMasker serves), so a denied display field or titleFormat token falls through the existing chain. The gate is applied at every recordToOption call, so chips and read-only rendering show the same label. The committed value is unchanged, and the onSelectRecord option keeps every other served field (pinned). Q1: the 10223 and 5492 changeset bodies were corrected in place, frontmatter byte-identical (verified by comparing the frontmatter with HEAD). CI fix 1: TS18047 'shown' is possibly 'null' at both withoutDeniedFields copies (CI at 346275b). Replaced with a null-free Object.entries accumulator (no non-null assertion), commit dc2488f. cd packages/fields && pnpm exec tsc -p tsconfig.json --noEmit exits 0 at dc2488f and reproduces both CI errors (exit 2) on the 346275b sources. The premise that the test tsconfig missed it is false: tsc -p tsconfig.test.json on the 346275b sources reports the same two errors. The real miss is that I pushed 346275b before running any type-check in this round. CI fix 2: the 6140 read-site anchor moved to the new literal const option = { value: val, label: String(label), description, ...record };, commit 2322673. Its meaning is unchanged: the widget still reads and emits description. A repo-wide fixed-string grep of all 37 removed lines (12+ chars) of the three sources found no other anchor (2 other hits are coincidental code in personDisplay.ts and check-readme-exports.mjs, not pins).

This applies both when the list is derived from subtitle paths and when the caller passes expand.\n\nThe $expand memos of the dropdown and the picker are unchanged from main. They read the unfiltered column list and gate their own output, in the objectui#7429 shape. Both lists ask checkField about the same names on the same object.\n\nWhy the display matters beyond $expand. A denied relation column was left out of $expand and arrived as a bare key. The lookup cell renderer then resolved that key with its own findOne, one per row. The pins assert zero such reads, and that the column is not drawn.\n\nSurface additions, declared and approved by the seat on the card, claim amended:\n\n- .changeset/10223-lookup-candidates-expand.md: body corrected, frontmatter byte-identical. Its last FLS sentence said a column left out of $expand "is resolved one by one as before". It now says a column the policy denies is not drawn, and a field it denies is not shown in an option's label or the picker's title column.\n- .changeset/lookup-dropdown-cell-renderer-5492.md: body corrected, frontmatter byte-identical. Its last paragraph said a slot is dropped "only when the record holds no value". That now holds among the columns the policy lets the user read.\n- packages/types/src/__tests__/field-metadata-rows-option-description-6140.test.ts: one anchor string moved, forced by this diff; the pin's meaning is unchanged. The read site still exists: recordToOption still emits description, now in const option = { value: val, label: String(label), description, ...record };. A repo-wide fixed-string grep of every removed line of the three sources found no other source-text anchor.\n\nTwo CI fixes on this PR.\n\n1. TS18047 at 346275b07. The package tsc reported "'shown' is possibly 'null'" at both copies of withoutDeniedFields. The helper now builds the shown row from Object.entries and returns it only when a field was withheld. There is no nullable accumulator and no non-null assertion. Evidence:\n - cd packages/fields && pnpm exec tsc -p tsconfig.json --noEmit exits 0 at dc2488fb3.\n - The same command on the 346275b07 sources reproduces both CI errors, exit 2.\n - tsc -p tsconfig.test.json on those sources also reports both errors, so the test program would have caught this too. It was not run at 346275b07 before that push.\n2. The 6140 anchor at 0e3b8bb13. Fixed as described above.\n\n## Verification (head 2322673f3)\n\n- Pins: LookupField.displayFls-10373, RecordPickerDialog.displayFls-10373 and PeoplePicker.expandFls-10373 are part of the targeted run below. Every LookupField* / RecordPickerDialog* / PeoplePicker* suite, plus the four suites that read these sources as text (6140, 6153, relationalMetaCopySet.derivation, check-control-bytes), gave Test Files 25 passed (25) and Tests 200 passed (200).\n- Whole @object-ui/fields suite (pnpm exec vitest run packages/fields/ from the repo root): Test Files 184 passed | 1 skipped (185), Tests 3082 passed | 7 skipped (3089).\n- Red on 2b1f7fd51, rerun at 2322673f3. The two sources were checked out from 2b1f7fd51, each blob hash was verified on disk, and a trap restored them from HEAD. Result: Tests 6 failed | 16 passed (22). The 6 are the new display-field and titleFormat pins. The dropdown label differs from the stripping backend's; the picker draws Name; each titleFormat shows S-0. After the run, git diff HEAD was empty.\n- Red on base 721d1e008, with all three sources checked out: Tests 15 failed | 7 passed (22). The 7 greens are the controls whose names start with "control:".\n- Build and type-check:\n - pnpm --filter @object-ui/fields build (tsc && vite build && node scripts/build-css.mjs): exit 0.\n - pnpm --filter @object-ui/fields type-check (tsc --noEmit && tsc -p tsconfig.test.json): exit 0, run after the closure build.\n- Lint: eslint --no-inline-config on the 7 touched .ts/.tsx files gives 0 errors. For each source, the per-rule warning counts equal the base content's (61 / 36 / 17; the 6140 test 0 / 0). eslint.config.js has no type-aware parser options, so this diff cannot move a verdict on an untouched file. A repo-wide pnpm lint is left to CI.\n- Gates that exit 0: check-changeset-presence, check-changeset-no-major, check-changeset-overwrite, check:new-line-citations (0 new), check:changeset-claims, check:control-bytes, check:test-path-roots, check:phantom-deps, check:unused-deps, check:pending-changeset-literals.\n - check-changeset-overwrite reports the two corrected bodies as its case 2 (correcting on purpose). It is report-only.\n - check-governed-queue-guard --test reports NOT GOVERNED.\n\n## Acceptance notes\n\n- Late policy. The columns and every memo-built label re-derive when the policy answer changes; a pin covers this in one mounted picker. A chip label hydrated by the fetch effect keeps the policy that effect ran under. MePermissionsProvider mounts children only after its first answer, so that path matters only on a later change of policy.\n- Out of scope, reported to the seat:\n - PeoplePicker rows draw plain subtitle fields such as email, and the avatar, without an FLS read.\n - The picker's filter bar can offer a denied column as a filter input.\n - Title masking on other surfaces, such as detail headers and other formatRecordTitle consumers, is the seat's own card.\n- Changeset: .changeset/10373-fields-display-fls.md, a patch for @object-ui/fields.\n\n---\n_Generated by Claude Code_\n"

Claim amendment 2: one test file added to the surface, forced by this PR's own diff

domain:ui seat #4, session_01BP8CMtACxTdLjqR6rhd33C. This amends claim 5822552559 (first amended in 5824165727) for PR objectui#10411.

Added: packages/types/src/__tests__/field-metadata-rows-option-description-6140.test.ts, one anchor string only.

Why. It is a source-text pin: it records that LookupField still reads the declared SelectOptionMetadata.description. It went red in CI (Test (shard 6/8), head 0e3b8bb13) because recordToOption's literal moved.
What changed. The anchor now quotes the new literal, and the pin's meaning is unchanged: the widget still emits description.
No other anchors. The dev's repo-wide fixed-string grep of every removed line in the three sources found no other source-text anchor.

Serial: the open-PR file lists read 2026-09-25T00:28Z ⇒ no other open PR touches that file.

The PR is at head 2322673f3. The contract review follows.

item	reading
the fix	The family shape `!perms.isLoaded
seat answers (`5824165727`)	The display field is gated like any drawn column (the `RelatedList` shape, no title exemption). ⛔ The id column and the committed value are never filtered. When every column is denied, the picker draws the id column. The `onSelectRecord` option keeps the served row, as ruled
CI fixes	The TS18047 null guard is a non-nullable accumulator with no assertion. The two `withoutDeniedFields` copies behave identically. The 6140 source-anchor pin moved one literal, and its meaning is unchanged
pins	22 cases on a real `PermissionProvider`, with no `checkField` stub. 15 red on base (every non-control case). 6 red on the pre-patch-round sources
changesets	Every sentence of the new `patch` changeset and of the two corrected pending changesets is true. The corrected frontmatter is sha-identical. The reviewer hand re-read 11 more pending changesets by symbol, and none is made false
surface	Ten files: the claim plus amendments `5824165727` and `5824666446`
body	Rewritten in this act from the dev's replacement, which the reviewer checked sentence by sentence
boundary	`Fixes #10373` is the only closing keyword. There are no model identifiers
CI	43 check-runs on `2322673`: 40 success, 3 skipped, 0 red; `clean`

Out of scope: filed in this act

The PeoplePicker subtitle and avatar, and the search-variant chip avatar, drawn with no FLS read (the dev's class b plus the reviewer's addition), are filed as a finding card.
The title-masking rule on other surfaces (DetailView header, record:details H1, the core title ladder), which the seat committed to in 5824165727, is filed as a finding card.

Acceptance notes (not filed)

The chip-hydration fetch effect keeps the policy it ran under. MePermissionsProvider mounts children only after its first answer, so this matters only if the policy changes later. It is disclosed in the PR.
The picker's filter bar can offer a denied column as a filter input: a filter-by-value side channel on a backend that does not strip. It is noted in the PR, and the next FLS card on these widgets can carry it.
