console record form dialog: clicking a collapsed section header remounts the whole dialog (a 1.5–4 s skeleton) and the section stays collapsed, so HotCRM Leads → New cannot open Company, Address, Additional or Privacy

Filing gate ①: a user-visible product defect, reproduced in a real browser. It came out of the domain:ui seat 1's landing reading for PR objectui#12556 (objectui#12548), and it is not that PR's: head and base behave alike.

finding · reach: every console user who opens HotCRM's Leads New or Edit dialog and tries to expand a section that starts collapsed. Reproduced in Chromium, at 1440×900, against HotCRM 63db83e (pinned @objectstack/cli 18.0.0-next.1), on objectui main 518a8e3084 and on PR #12556's head 88bfef068f alike:

In the "Create Lead" dialog, and in the same dialog in edit mode (?form=ID), clicking the header of a collapsed section (Company Information, Address, Additional Information, Privacy) remounts the whole dialog.
A skeleton shows for about 1.5–4 s, and the dialog comes back with that section still collapsed. So those four sections cannot be opened in the dialog at all.
The full-page create route /apps/crm_enterprise/crm_lead/new expands the same sections normally.

Readings, screenshots and scripts are in the seat's scratch (browser-12556/, readNew.cjs), not in the repo. The producer is not named yet. Candidates to check first:

the collapse toggle's state living above the dialog's key, so a toggle re-keys or re-mounts ModalForm (packages/plugin-form/src/ModalForm.tsx, resolveSectionCollapse, fieldGroups.ts);
the console host's ?form= deep-link state re-opening the dialog on a re-render.

Reader who acts: triage grades this card. The likely lane is domain:ui (@object-ui/plugin-form and/or the console's form host). ⛔ This is not a claim.

Dedupe (MCP search_issues, scope objectstack-ai/objectui, all states, read 2026-10-15T18:20Z): "form dialog collapsed section header click remounts dialog skeleton section stays collapsed cannot expand" → 0 results.

Acceptance (proposed)

A test on the real ModalForm, mounted the way the console mounts it: clicking a collapsed section's header expands it in place. The dialog does not remount; pin the form's identity or a mount counter. A typed value in another section survives the toggle.
A browser reading on HotCRM Leads → New at 1440: Company Information opens on click and shows its fields.

Attribution: filed by the domain:ui seat 1 in session session_01JZnppgHRp4sREcouhkQYDB (account sunhaolin), from the PR objectui#12556 landing reading.

Read fresh. In the console's record form dialog (HotCRM Leads → New, and the same dialog in edit mode), clicking a collapsed section header remounts the whole dialog: a skeleton for 1.5–4 s, and it comes back still collapsed.

So Company Information, Address, Additional Information and Privacy cannot be opened in the dialog at all.
The full-page create route expands them normally.
Reproduced in Chromium on objectui main 518a8e3084 and on PR fix(plugin-form): each form section draws its own columns count per row (objectui#12548) #12556's head alike.

Grade p1: the dialog is the console's primary create and edit path, and on a shipped app's main object a user cannot reach four sections' fields from it. The full page is a workaround the user has no reason to know.

Lane domain:ui (@object-ui/plugin-form ModalForm and/or the console's form host).

Scope:

First name the producer: whether the collapse state lives above the dialog's key and re-keys ModalForm, or the ?form= deep-link state re-opens the dialog on re-render.
The card's proposed acceptance:
- on the real ModalForm mounted as the console mounts it, a header click expands in place with no remount (pin a mount counter);
- a typed value in another section survives the toggle;
- a browser reading on Leads → New at 1440.
Order: PR fix(plugin-form): each form section draws its own columns count per row (objectui#12548) #12556 (console record forms: a section whose authored columns does not divide the form's one grid draws the wrong number of fields per row (HotCRM Leads → New: a two-column section draws one field per row) #12548) touches the same dialog's section layout, so it lands first or this rebases on it.

finding leaves on grading.

Serial constraints cleared: seat 1's open PR #12556 (objectui#12548) and draft PR #12546 (objectui#12521) both edit packages/plugin-form/src/ModalForm.tsx and autoLayout.ts. Triage orders PR #12556 first. This card's PR merges origin/main after each of them lands, as a merge commit, never a rebase. If it is ready first, it waits for #12556. The fix is kept to the toggle and mount path, away from the section-layout code both PRs change.

The first render of a type that a collapsed section was hiding suspended past ModalForm to the host's nearest Suspense. The console mounts ModalForm beside its routes, so that boundary is ConsoleShell's root one, and the whole console, dialog included, was swapped for the root fallback. The full-page route hides only its page. Neither triage candidate is the producer: the collapse state is ModalForm's own useState, the dialog key (object name plus id or new) cannot change on a toggle, the header is a div with role=button (A2 disproved), and the toggled value wins over the declared one (A3 pinned). Fix: ModalForm wraps both dialog bodies in a Suspense with a ModalFormBodyPending fallback, the FlowRunner precedent. A per-widget boundary in components form.tsx was tried and reverted on the branch because it changed every form's readiness contract (a pinned test went red); form.tsx is byte-equal to main. A1: the dialog-off-screen half was measured in Chromium. The console-only remount (comes back collapsed) did not reproduce without the console's ancestors and is NOT MEASURED; the landing seat's HotCRM reading confirms it.

PR #12571 merged through the merge queue as 0081cdc, which is on main. Verified by content: all 4 of the PR's files on origin/main are blob-identical to the accepted head cc9467a.

What changed: the record dialog now owns the wait while a lazy field widget loads. Before, opening a collapsed section suspended past ModalForm to the console's root boundary and hid the whole console. Now the dialog's header and footer stay, its body shows a placeholder, and the form keeps its state.
Owed by the maintainer's check: the HotCRM browser reading on Leads → New at 1440, where clicking Company Information should open it. The console-only "comes back collapsed" half was not reproduced outside the console. If it persists, this card reopens.
Seat 2 note: draft PR fix(plugin-form): a record dialog with no authored layout opens bounded with a two-column grid (objectui#12521) #12546 (objectui#12521) also edits ModalForm.tsx and now merges main.

pm:dispatched is removed with this note. The card closes completed on merge.
