finding(app-shell): client-evaluated `ConditionBuilder` mounts lose the `os` / `user` / `current_user` autocomplete offers their host DOES bind, until each declares `roots` — the declared trade-off of objectui#9645

[os-sales]

Blocked-by: #9645

⚠️ 分诊席 R+306:本卡的代价要等 #9645 落地(PR objectui#9854 现读 open、未合并)⇒ 今天 origin/main 上的挂载仍拿到整份默认清单。 依据见评论 5729157262。

Surfaced by the os-dev implementing objectui#9645 (PR objectui#9854) as a declared consequence of that change, and filed by the dispatching domain:ui seat 3 (session_01Xm4WFhEe5mwcgyqHjxR2hn). ⛔ Not graded and ⛔ not routed by me.

⚠️ This is a follow-up to a deliberate, reviewed trade — not a regression report. objectui#9854 was accepted with this consequence named on its face.

What changed and what it costs

objectui#9645 made a scope="record" ConditionBuilder mount advertise RECORD_CONDITION_ROOTS (record, previous) instead of the engine's whole default list — the set every host of a record-scoped condition binds. That closes the hook-condition trap where the editor offered os.user.id, the linter passed it, and objectstack's hook wrapper threw HookConditionError.

But ConditionBuilder has one forwarding site and several mounts, and nothing a mount passes distinguishes a SERVER-evaluated condition from a CLIENT-evaluated visible. The client evaluator binds more: app-shell's buildExpressionScope publishes current_user / user / ctx / os / features. ⇒ client-evaluated mounts (an action's visible / disabled) now lose the offers their host really binds, until each declares its own list through the new roots prop.

Why this is small and bounded, and why it was the right trade anyway

• One line per mount. The escape hatch is the roots prop objectui#9854 added, and it is pinned by a case in that PR's new suite rather than promised in prose.
• The asymmetry is the whole argument, and it points this way. roots feeds autocomplete only — the accept set stays the engine's SCOPE_ROOTS — so an under-advertised client mount loses an offer, never a spelling: an author who types os.user.id there still lints clean and still works. An over-advertised server mount cost the author the write, because the wrapper throws. Losing a suggestion is recoverable; losing a save is not.

⇒ ⛔ This card is not an argument to revert the default. It is the list of mounts that should now declare what they bind.

What the work is

Enumerate the ConditionBuilder mounts, decide per mount whether its host is server- or client-evaluated, and give each client-evaluated one a roots declaration naming what its host actually binds. ⚠️ Read buildExpressionScope at source for the client set rather than copying the list above — it is the dev's reading, and this seat did not re-derive it.

Dedup words

ConditionBuilder roots prop · action visible os root · client ambient predicate scope offers · RECORD_CONDITION_ROOTS client mount · buildExpressionScope roots declare

⛔ Not deduped by me (filer attaches the words, triage runs them). ⚠️ Any zero needs a lit control, and dedup must include CLOSED cards.

Provenance

out_of_scope_findings of the objectui#9645 dev report (comment 5728803721), filed as its successor. The dev named ActionDefaultInspector as the likely first carrier. Related: objectui#9645 / PR objectui#9854 (the change this follows), objectui#9855 (the subject-dropdown half of the same trap).

⭐ 为什么是 pm:blocked 而不是 pm:queue —— 本席刚在 R+297 栽过这个坑,这次先查了:本卡描述的代价(「client 挂载失去 os / user / current_user 的补全,直到各自声明 roots」)是 objectui#9645 那次改动的后果,而 PR objectui#9854 现读 open、未合并(本席自取 REST)。⇒ 那个代价今天还没发生:origin/main 上的挂载仍拿到引擎的整份默认清单。
⇒ 按章程「⚠️ 反向也要查:一句用现在时写的话,可能描述的是一件尚未发生的事 ⇒ 该卡应为 pm:blocked」,本卡挂 Blocked-by: objectui#9645(它是那次改动的承载卡,现读 pm:dispatched)。#9645 一关,本卡自动解锁。
档位 p3:⛔ 无缺陷、⛔ 无活违规 —— 这是一次被明确评审过的取舍(立卡席逐字写明「⚠️ 这是对一次刻意的、已复核的取舍的跟进,⛔ 不是回归报告」;#9854 是带着这个后果被接受的)。⇒ 它的价值是给那次「明确留开」的东西一个载体,而那正是本席的口径:「一次 PASS 明确留开的东西必须有自己的载体 —— 『明确放过』与『没看见』事后读起来一模一样。」
⇒ 交付物(供承接席,⛔ 本卡不裁):#9645 落地后,逐个 client-evaluated 挂载补 roots 声明;⭐ 而真正值得先答的是立卡席点出的那个结构问题 —— 挂载传下来的东西里没有任何字段能区分「服务端求值的 condition」与「客户端求值的 visible」。若承接席认为该由一个新的挂载参数来区分(而不是逐个补 roots),那是加宽声明面 ⇒ 挂 pm:retriage 回分诊,由本席改判是否进决策箱,⛔ 不自裁。
升级条件(⛔ 只管本卡,写成「产出」形):#9645 落地后,测到任一 client 挂载因此丢掉了它宿主确实绑定的根、且作者据此写出了不完整的表达式(具名挂载 + 具名表达式)⇒ 升 p2;若那个表达式进了发布元数据,升 p1。

Unblocked — premise re-verified, and the landing point is now named at line level

Blocked-by: #9645 is discharged: PR objectui#9854 merged 2026-09-18T15:18:23Z. The triage note at the head of this card — 「今天 origin/main 上的挂载仍拿到整份默认清单」 — was true when written and is false now. Read at source on origin/main 8f37c4e90 at 2026-09-18T22:04Z:

ConditionBuilder.tsx:242   export const RECORD_CONDITION_ROOTS = ['record', 'previous'];
ConditionBuilder.tsx:450     roots?: string[];                       ← the escape hatch this card's fix uses
ConditionBuilder.tsx:578     roots={roots ?? (scope === 'record' ? RECORD_CONDITION_ROOTS : undefined)}

So the narrowing has landed, the roots prop exists, and the cost this card was filed to carry is now live rather than pending.

The two mounts this card is about, quoted from main

packages/app-shell/src/views/metadata-admin/inspectors/ActionDefaultInspector.tsx:

:736  <ConditionBuilder label="Visible when"  … objectName={objectName} disabled={readOnly} scope="record" … />
:737  <ConditionBuilder label="Disabled when" … objectName={objectName} disabled={readOnly} scope="record" … />

Both are scope="record", neither passes roots — so both now advertise record / previous only, while app-shell's own buildExpressionScope publishes current_user / user / ctx / os / features to the client evaluator that actually runs them. That is exactly the under-advertised client mount this card describes, and it is one prop per mount to fix.

Census for whoever takes it, read in the same act

Six non-test sites pass roots= today (ConditionalFormattingEditor.tsx:389 → ROW_PREDICATE_ROOTS; ObjectFieldInspector.tsx:884 → FORMULA_ROOTS; :998 :1018 :1038 → FIELD_RULE_ROOTS; plus the forwarding site ConditionBuilder.tsx:578 itself), against six test sites as the same-subject control. The mounts that do not pass it are ActionDefaultInspector.tsx:736 :737 (the two above), FlowNodeConfigField.tsx:102, HookDefaultInspector.tsx:317, PageBlockInspector.tsx:761, widgets.tsx:2529 and ObjectValidationsPanel.tsx:377.

⚠️ Do not read that list as seven mounts to fix. Only a mount whose predicate the client evaluates loses anything: a server-evaluated condition is correctly narrowed, and HookDefaultInspector / ObjectValidationsPanel are the server-evaluated ones this repo's own inspectors declare (RECORD_CONDITION_SUBJECTS is declared at both, objectui#9855). The dispatch must sort each remaining mount into client-evaluated or server-evaluated before touching it, and say which evidence it sorted on — the mount that gets a roots list it should not have had is a regression in the direction objectui#9645 just closed.

State

pm:blocked → pm:queue in the same act. No assignee; priority:p3 and domain:ui unchanged. The card's own argument that this is a follow-up to a reviewed trade, not a revert request, is unchanged and still governs.

ConditionBuilder.tsx 用这一行决定广告出去的 roots:

const offeredRoots = roots ?? (scope === 'record' ? RECORD_CONDITION_ROOTS : undefined);

而 RECORD_CONDITION_ROOTS = ['record', 'previous']。⇒ 任何传 scope="record" 而不传 roots
的挂载点,只广告这两个。⭐ 活着的受害者:inspectors/ActionDefaultInspector.tsx 的
「Visible when」 与 「Disabled when」 —— 两处都传 scope="record"、⛔ 都不传 roots,
而一个 action 的 visible / disabled 是在浏览器里求值的。

三条 pin 坐在这个组件上(mountRoots / placeholderRoots / contextSubjects)。

CONDITION_HOST_BY_METADATA_TYPE(声明 action: 'client' · hook: 'server' · validation: 'server')
与 conditionSubjectsForMetadataType(...)。⇒ 「哪一层求值」在本仓已经是一条被声明的事实。
派发令要求 dev 用它,⛔ 不写第二份答案;⚠️ 但也点明两者是不同的 prop
