console: a record-button flow whose write step dropped a read-only field shows a warning toast naming the fields (console half of #32861)

Part of #32861
Blocked-by: #33007

Filing category: ① product defect, in-flight split (references/execution-duties.md in-scope sub-issue; priority inherited from #32861, p1). The server half is PR #33007 (Part of #32861); this card carries the card's Work 2, the console toast, and #32861 closes when this lands.

维护者速读

员工点按钮启动流程，流程想写的字段是只读的，写入被丢掉、按钮却答「成功」，员工什么都看不到。PR #33007 让流程的回答里带上「哪些字段没写进去、为什么」；这张卡让控制台把它弹成黄色警告，显示字段的中文名。

Business reason

The #32666 case: a member clicks 「提交审批」, the flow's update_record step writes status, which is readonly: true; the write is dropped, the run succeeds, the record stays 「草稿」, and the console says nothing. After PR #33007 the flow-action answer carries droppedFields (DroppedFieldsEvent: object, fields, reason; omit-when-empty) on REST and MCP. Nothing in the console reads it yet.

Expected

A person who starts a flow from a record action (and from a screen flow's resume) sees a warning toast in their locale when the answer carries droppedFields: the step ran, these fields (by label) were not written because they are read-only. No toast when the answer carries none. The existing detail.writeStripped* wording fits it.

What the server half measured (PR #33007, Acceptance notes)

The wire parse of a droppedFields entry (isWireDroppedFieldsEntry, asDroppedFieldsNotice, the skew arm for an unknown reason) is private to ui/packages/data-objectstack. The console's flow launch (ui/packages/app-shell/src/utils/flowLaunch.ts) does not go through the adapter: export the parser, ⛔ no second copy.
writeWarningToast.emitWriteWarning needs the adapter (field labels), which neither launch host (hooks/useConsoleActionRuntime.tsx, views/RecordDetailView.tsx) holds today.
A run that paused at a screen node delivers the drop on the resume answer, which views/FlowRunner.tsx reads: a third reader.
The answer's droppedFields is complete only for the run's own write steps and a subflow child that completes without pausing. A map item's run and a subflow child that paused and resumed do not roll up yet (automation: a flow's answer carries the dropped-field fact of its map items and of a subflow child that paused and resumed (delegated half of #32861) #33019, server lane). Until automation: a flow's answer carries the dropped-field fact of its map items and of a subflow child that paused and resumed (delegated half of #32861) #33019 lands, the toast reads a present member as a drop, and ⛔ never reads an absent member as "nothing was dropped" for those shapes (contract review of PR fix(automation): a flow run's answer names the read-only fields its write steps dropped (#32861) #33007, record 6843734657, S1).

Work

One shared reader of the answer's droppedFields for the three hosts above, through the existing parser and writeWarningToast.
Pins: the A runtime-authored flow that writes a readonly field as the user publishes clean; the button runs, reports success and changes nothing (flow-update-readonly-field is not run at the save/publish gate) #32666 shape (readonly status, flow behind a record action) yields the toast on the click with the field label; a clean click yields none; the resume path yields it. Ablate and show red.
Declarations per AGENTS.md (console only: Clause-②: none expected; changeset per the ui packages' rule).

Reader: domain:ui lane, once PR #33007 merges.
Dedupe: repo:objectstack-ai/objectstack is:issue droppedFields toast flow → #32861 (parent) only.

Container & model: M, mode:thread, model: default tier (dispatch-gates --tier: no path-derived mandate), effort: high
Clause-②: yes (widening: the parser is exported from @object-ui/data-objectstack's entry; an i18n key, if added, widens too; the dev measures and reports)
Metadata-protocol: none
Responsibility: owed by the dev (pre-existing: the console never read droppedFields, which PR #33007 introduced)
Thread-read: 6845483689
Premise: holds as read: Blocked-by: #33007 merged fc453283e (unblock 6845483689); the flow-action answer now carries droppedFields on REST and MCP and nothing in the console reads it. Card's item 4 (a paused subflow child's drops not reaching the parent's resume answer) is a server note: if the resume reader needs it, the dev reports it and the seat routes it to domain:server
Serial constraints cleared: this seat has no other card in flight; domain:ui#2 is offline; #32994's console/ai/** files are merged and disjoint.
