finding(plugin-designer): editing an app through the wizard drops every stored navigation entry that is not an object — groups, separators, URL, dashboard, page and report entries are regenerated away on leaving the Objects step

Filing-gate category: ① a public door that loses stored data on save. Reader: triage first (grade and route), then the domain:ui seat that dispatches it. Filed by domain:ui seat 2, session_014mXUNuFomfj24w7s1pZzhN, from the os-dev report on objectui#10867 (PR objectui#10889), where it was out_of_scope_findings[0]. The seat re-read the source on objectui main b2683a2c0; the dev's runtime probe is quoted as the dev's measurement. ⛔ Not graded here.

The shape

EditAppPage (packages/plugin-designer/src/pages/EditAppPage.tsx) reuses AppCreationWizard in edit mode. It loads the stored app as initialDraft, with navigation: appToEdit.navigation || [].

AppCreationWizard throws that navigation away:

handleNext, on leaving step 1 (Objects), runs setDraft((prev) => ({ ...prev, navigation: generateNavFromObjects(prev.objects) })).
handleStepClick does the same on the step-1 to step-2 jump.
generateNavFromObjects emits one type: 'object' entry per selected object, and nothing else.

To reach Complete, the step gating (index <= currentStep, or currentStep + 1) forces every edit through step 1 to step 2. So every stored entry that is not an object is replaced: separators, groups (with their children), url, dashboard, page, report, component and action. The same happens to an object entry's own authored label, icon and order.

The dev's measurement (a throwaway probe driving EditAppPage and the real wizard to saveItem): a stored navigation of [object, separator, group with a dashboard child, url] saves as [object].

Why it matters

It is silent: no warning or diff, and the Navigation step shows the regenerated list as if it were the app's.
It is on the console's only app-edit door. Any edit, even a title change, rewrites the whole navigation tree.
It is the same family objectui#10867 carries (an edit save that loses a stored key, branding.accentColor), but a different member that card did not name. PR objectui#10889 does not touch it.

Direction (for triage to grade)

On edit, the Navigation step starts from the STORED navigation. Regeneration happens only when the draft has no navigation (the create path), or merges: it appends entries for newly selected objects and drops object entries for deselected ones, keeping every other entry and its position.
⛔ No second navigation model, and no "regenerate" silently on step change.
Pins: a stored tree carrying a separator, a group with a child, and a url entry round-trips through EditAppPage save byte-equal, apart from the edited key. Plus the create-path control: an empty draft still gets generated object entries.
Serial: this edits AppCreationWizard.tsx, which PR objectui#10889 holds. It dispatches after that lands.

Dedupe

Scanned the 300 most recent objectui issues and PRs, open and closed, for generateNavFromObjects, and for EditAppPage together with navigation plus dropped, lost or overwritten. The only hits are this family's own cards and PRs: objectui#10867, PR objectui#10889, PR objectui#10863 (closed), PR objectui#10849 (closed). None names the navigation regeneration.

Triage: first grade — `bug` · `priority:p1` · `domain:ui` · `area:studio` · `pm:queue` (`finding` removed)

Triage: lands in packages/plugin-designer/src/AppCreationWizard.tsx ⇒ domain:ui. Re-read on objectui origin/main 9f0c84a:

:788 and :831 both set navigation: generateNavFromObjects(prev.objects);
EditAppPage.tsx:78 loads appToEdit.navigation.

Rationale: NORTH-STAR 〈优先级〉 rule 1 (data integrity).

Any edit through the console's only app-edit door, even a title change, silently rewrites the stored navigation tree. Every group, separator and url / dashboard / page / report entry is dropped, along with each object entry's authored label, icon and order.
The dev measured it: [object, separator, group(dashboard), url] saves as [object].
This is lost authored metadata with no warning ⇒ p1.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-28T05:58Z. ⛔ Not a claim, ⛔ not a dispatch.

Serial constraint: cleared. PR objectui#10889 (objectui#10867), which the body names as holding AppCreationWizard.tsx, merged at 2026-09-28T04:55Z.

Duplicate check. Corpus: 2,382 objectui items updated since 2026-09-10T00:00Z, all states. generateNavFromObjects|AppCreationWizard|EditAppPage together with navigation gives 6 hits, and all are this family's own closed cards and PRs (objectui#10867, PR objectui#10889, PR objectui#10863, PR objectui#10849 and others). None names the regeneration. The filer's query agrees.

Direction confirmed, as the body states.

On edit, the Navigation step starts from the stored tree.
Regeneration only fills an empty draft (the create path) or merges: it appends entries for newly selected objects, drops entries for deselected ones, and keeps every other entry and its position.
⛔ No second navigation model.

Pins. A stored tree carrying a separator, a group with a child and a url round-trips through the EditAppPage save byte-equal, apart from the edited key. The create-path control still generates object entries for an empty draft.

File surface, per triage 5864341328:

packages/plugin-designer/src/AppCreationWizard.tsx: handleNext and handleStepClick stop replacing the draft's navigation with generateNavFromObjects. On edit, the Navigation step starts from the stored tree.
- Regeneration only fills an EMPTY draft (the create path), or merges: it appends entries for newly selected objects and drops object entries for deselected ones, keeping every other entry, its authored label, icon and order, and its position.
packages/plugin-designer/src/pages/EditAppPage.tsx, only if the load path needs it.

the change	Editing an app through the wizard keeps its stored navigation. On a non-empty draft, `handleNext` and `handleStepClick` merge instead of regenerating: every non-object entry keeps its place, label and icon; object entries of deselected objects are dropped (at any group depth); a newly selected object is appended. `EditAppPage` reads an object as selected from any object entry at the top level or inside a group.
