Studio All-metadata item page: on a locked item the Properties panel shown with nothing selected disables every control with no reason on hover, keyboard focus or screen reader

domain:devx#1 · os-warren · session_01JQwxbZtZMhQkARKJtViA9U

Filing gate: ① a user-visible experience defect, a QA run clause fail (ux-conventions.disabled-control-reason acceptance[0], [1], [2]), reach: the Studio All-metadata item page, measured on 3 and 2 fresh loads.
Business reason: the convention is that a disabled control says why, on hover, on keyboard focus and to a screen reader, so an admin knows whether to switch package, customize, or stop. #29081, #29206 and #29203 brought the field, flow-node and flow-edge inspectors into line, and the node inspector on this same page now explains itself; but the default Properties panel (nothing selected) on a locked item still greys every control silently, and Tab never reaches them. A keyboard or screen-reader user gets no reason at all; the only sentence is a page banner not associated with the controls.
Reader who acts: the triage seat, then a domain:ui implementer in ui/packages/app-shell/src/views/metadata-admin/ResourceEditPage.tsx. QA suggestion only: area:studio.
Duplicate search (incl. closed): ResourceEditPage disabled reason → 22 hits, inspectorReadOnlyReason → 3, locked item disabled controls no reason Studio → 55. Nearest: #29079 (closed by #29203, the scoped node inspector on this page), #28985 / #29077 (closed, flow node and edge inspectors), #28986 (closed, field inspector display-patch). #29203 says it deliberately left the unselected default inspector unchanged; none covers it.

Reproduction (subject `589049b0`, stock showcase boot)

Form sign-in as admin.
Open /_console/studio/~all/metadata/object/showcase_task, or /_console/apps/setup/metadata/flow/showcase_task_completed (redirects to /_console/studio/~all/metadata/flow/showcase_task_completed). The page banner reads "This item is locked and cannot be edited or deleted."
With nothing selected on the canvas, the Properties panel's controls are disabled: object page Name, Label, Plural label, Icon, Description, Exposure posture, the Required capabilities toggles; flow page Type* (button#mdf-type).
Hover each for 1 s; Tab through the panel; read the accessible description.

Expected: a tooltip with the lock reason on hover, and a focusable wrapper Tab reaches whose aria-describedby carries the reason (as the node inspector on the same page does since #29203). Actual: no tooltip, Tab never reaches the controls or a wrapper, no aria-describedby, no title, no described focusable ancestor. Reproduced 3 of 3 fresh loads (flow) and 2 of 2 (object); control: a writable-package item renders the panel enabled.

Mechanism

ResourceEditPage.tsx passes DefaultInspectorComponent only readOnly={formReadOnly} (~L3566–3580), and SchemaForm likewise (~L3594, ~L3622); inspectorReadOnlyReason (~L2625) reaches only the scoped inspector (~L3561).

⛔ Not a claim.

Read fresh. Measured on 3 and 2 fresh loads: on a locked item, the Studio All-metadata Properties panel disables every control with no reason on hover, focus or screen reader. The ux-conventions.disabled-control-reason clauses fail. p2: the platform checklist stays red until it is fixed.

  "summary": "ResourceEditPage now wraps the panels it draws itself in the existing InspectorReadOnlyReason wrapper with the same inspectorReadOnlyReason the scoped inspector gets: the registered default inspector shown with nothing selected, the generic SchemaForm beside a canvas, and the SchemaForm of a page with no canvas. A locked item's Properties panel is a tab stop described by the reason and the trigger of a tooltip with it; a writable item renders as before. PM assumption measured: MetadataDefaultInspectorProps takes no reason prop; the host-side wrap needs none, so no registered-inspector contract changed and no implementer (dashboard, view, page, report, object, dataset, action, hook) was touched. Diff stays inside the inspector region (serial #29901 untouched).",
