Fix the plural in the measurement-settings heading.

"Set measurements settings" doubles up a noun that only needs one. Use "Set measurement settings". The step heading is user-visible, so the stray s will be seen by every tester who wanders past.

Update the matching string in locales/zh.json only if the Chinese wording needs a parallel change; the current 「设置测量参数」 already reads correctly.

✏️ Proposed wording fix
-    "measurementSettings": "3. Set measurements settings",
+    "measurementSettings": "3. Set measurement settings",

Note: src/renderer/src/panel/PanelApp.test.ts line 163 and its assertion at line 628 hard-code the current text, so they need the same edit.

Bound benchmark job polling and support cancellation.

Line 318 repeats forever when a submitted job stays non-terminal or never appears in the jobs response. The IPC call then never settles. Add a user-cancellable deadline and propagate its AbortSignal through the fetch and delay operations.

Serialize benchmark runs for each runtime session.

Line 183 accepts concurrent runs for the same sessionId. Each run submits work to the same ComfyUI instance, and concurrent runs can overwrite the same session results.json and aggregates.json. Track an in-flight benchmark by sessionId, reject a second request, and clear the guard in finally.

Share the benchmark result type with the test fixtures.

installMockApi assigns the inferred API through unknown as { api: typeof api }, so TypeScript does not check runBenchmarkWorkflow against ElectronApi. The current result is compatible, but future contract changes can leave the mock compiling with the wrong shape. Extract RunBenchmarkWorkflowResult, use it in ElectronApi, and type both benchmark result paths with it.

Preserve the workflow when deletion is skipped

deleteBenchmarkWorkflow returns Promise<void> and exits when results.json exists. The IPC handler still returns { ok: true }, so deleteWorkflow() clears workflowFilePath although the file remains on disk. Return a distinct preserved status and clear the UI path only after deletion succeeds.

🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Guard the submit step against an interleaved stop.

stopBenchmark can run while the launch promise is still pending. It clears benchmarkInstallationId and stops the session, but runBenchmark does not consult that state after the await. The submit call then fires against a session that is already stopped, and the log gets a submitFailed line right after the user asked for a stop. That is a puzzling parting shot for a session the user politely dismissed.

Track a run token and re-check it before submitting.

Pin the log auto-scroll to the bottom only.

The watcher scrolls on every output change. A user who scrolls up to read an earlier stack trace gets snapped back down on the next line. Check that the pane is already near the bottom before you scroll, so the log stops playing tug-of-war.

Add a signed-out empty state.

The title-bar menu always shows "Performance Test" — buildTitlePopupMenuItems in src/main/popups/titlePopup.ts (lines 801-805) never gates the entry on sign-in state. Both the workspace bar and the whole content block are gated on authStore.isSignedIn. A signed-out user therefore opens a window that shows a wordmark, one sentence, and a great deal of nothing. The page goes quiet when it should give a cue.

Render a short sign-in prompt when authStore.isSignedIn is false.

Preserve submitted-run state when a later stage fails.

A failure in polling, persistence, hardware collection, or summary validation occurs after ComfyUI accepts prompts. The catch response still reports submitted: 0 and totalSubmitted: 0.

The renderer can then retry work that is already running or completed. This turns a late failure into a zero-run tale and can duplicate benchmark workload.

Track accepted prompt IDs and counts across execution stages. Return the partial submission state with the failure. Also preserve partial prompt IDs when submission fails after accepting some runs.

Allow host windows to fit narrow work areas.

createHostWindow applies minWidth: 1200 to both install-backed and chooser hosts. On a display or split-screen work area narrower than 1200, users cannot resize an oversized host to fit that region. This limits side-by-side use, but it does not make content permanently inaccessible because OS window management can still maximize or move the window.

Keep the previous minimum:

Bound the comparison image dimensions.

Both dimensions grow with data.runs.length. Selecting 100 runs produces approximately 270 million canvas pixels. createResultsPng can then exhaust renderer memory or fail to encode the image.

Limit exported runs, paginate the image, or use a bounded layout. Cap the run count so the benchmark does not become a memory benchmark.

Use stable IDs for entity filters.

Workspace and instance options use display names as identities. Two workspaces or instances can have the same name. Selecting that name then includes records from both entities.

Use workspace.id and instance.id as option values. Add a distinct sentinel for unmanaged workspaces. Disambiguate duplicate labels when necessary.

PerformanceTestResultsSummary.hardware is nullable. The export button remains available when statistics and system information exist, but this guard rejects every export for that valid result shape.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Do not persist Personal before auth hydration.

authStore.status starts signed out while fetchStatus() awaits getAuthStatus(). The immediate watcher can therefore call setSelectedWorkspace(PERSONAL_WORKSPACE_ID) before the persisted session arrives. That helper writes DASHBOARD_WORKSPACE_SETTING, which can replace the user's saved workspace. Keep this fallback in memory only.

     if (!next.signedIn) {
-      setSelectedWorkspace(PERSONAL_WORKSPACE_ID)

<title>Button Pattern | APG | WAI | W3C</title> https://www.w3.org/WAI/ARIA/apg/patterns/button/ Button Pattern | APG | WAI | W3C ## About This Pattern A button is a widget that enables users to trigger an action or event, such as submitting a form, opening a dialog, canceling an action, or performing a delete operation. A common convention for informing users that a button launches a dialog is to append "…" (ellipsis) to the button label, e.g., "Save as…". In addition to the ordinary button widget, WAI-ARIA supports 2 other types of buttons: - Toggle button: A two-state button that can be either off (not pressed) or on (pressed). To tell assistive technologies that a button is a toggle button, specify a value for the attribute aria-pressed. For example, a button labelled mute in an audio player could indicate that sound is muted by setting the pressed state true. Important: it is critical the label on a toggle does not change when its state changes. In this example, when the pressed state is true, the label remains "Mute" so a screen reader would say something like "Mute toggle button pressed". Alternatively, if the design were to call for the button label to change from "Mute" to "Unmute," the aria-pressed attribute would not be needed. - Menu button: as described in the menu button pattern, a button is revealed to assistive technologies as a menu button if it has the property aria-haspopup set to either `menu` or `true`. ### Note The types of actions performed by buttons are distinctly different from the function of a link (see link pattern). It is important that both the appearance and role of a widget match the function it provides. Nevertheless, elements occasionally have the visual style of a link but perform the action of a button. In such cases, giving the element role `button` helps assistive technology users understand the function of the element. However, a better solution is to adjust the visual design so it matches the function and ARIA role. ## Examples - Button Examples: Examples of clickable HTML `div` and `span` elements made into accessible command and toggle buttons. - Button Examples (IDL): Examples of clickable HTML `div` and `span` elements made into accessible command and toggle buttons. This example uses the IDL Interface. ## Keyboard Interaction When the button has focus: - Space: Activates the button. - Enter: Activates the button. - Following button activation, focus is set depending on the type of action the button performs. For example: - If activating the button opens a dialog, the focus moves inside the dialog. (see dialog pattern) - If activating the button closes a dialog, focus typically returns to the button that opened the dialog unless the function performed in the dialog context logically leads to a different element. For example, activating a cancel button in a dialog returns focus to the button that opened the dialog. However, if the dialog were confirming the action of deleting the page from which it was opened, the focus would logically move to a new context. - If activating the button does not dismiss the current context, then focus typically remains on the button after activation, e.g., an Apply or Recalculate button. - If the button action indicates a context change, such as move to next step in a wizard or add another search criteria, then it is often appropriate to move focus to the starting point for that action. - If the button is activated with a shortcut key, the focus usually remains in the context from which the shortcut key was activated. For example, if Alt + U were assigned to an "Up" button that moves the currently focused item in a list one position higher in the list, pressing Alt + U when the focus is in the list would not move the focus from the list. ## WAI-ARIA Roles, States, and Properties - The button has role of button. - The `button` has an accessible label.

Before using it for any purpose, read this to understand why. This is an illustrative example of one way of using ARIA that conforms with the ARIA specification. - There may be support gaps in some browser and assistive technology combinations, especially for mobile/touch devices. Testing code based on this example with assistive technologies is essential before considering use in production systems. - The ARIA and Assistive Technologies Project is developing measurements of assistive technology support for APG examples. - Robust accessibility can be further optimized by choosing implementation patterns that maximize use of semantic HTML and heeding the warning that No ARIA is better than Bad ARIA. ## About This Example The following command and toggle button examples demonstrate the Button Pattern. Similar examples include: - Navigation Menu Button: A button that opens a menu of items that behave as links. - Action Menu Button Example Using `element.focus()`: A button that opens a menu of actions or commands where focus in the menu is managed using `element.focus()`. - Action Menu Button Example Using `aria-activedescendant`: A button that opens a menu of actions or commands where focus in the menu is managed using `aria-activedescendant`. ## Example This Print action button uses a `div` element. This Mute toggle button uses an `a` element. ## Keyboard Support | Key | Function | | --- | --- | | Enter | Activates the button. | | Space | Activates the button. | ## Role, Property, State, and Tabindex Attributes | Role | Attribute | Element | Usage | | --- | --- | --- | --- | | `button` | | `div`, `a` | Identifies the element as a `button` widget. Accessible name for the button is defined by the text content of the element. | | | `tabindex="0"` | `div`, `a` | Includes the element in the tab sequence. Needed on the `a` element because it does not have a `href` attribute. | | | `aria-pressed="false"` | `a` | Identifies the button as a toggle button. Indicates the toggle button is not pressed. | | | `aria-pressed="true"` | `a` | Identifies the button as a toggle button. Indicates the toggle button is pressed. | ## Assistive Technology Support ## JavaScript and CSS Source Code - CSS: button.css - JavaScript: button.js ## HTML Source Code To copy the following HTML code, please open it in CodePen.

It describes considerations that might not be evident to most authors from the WAI-ARIA specification alone and recommends approaches to make widgets, navigation, and behaviors accessible using WAI-ARIA roles, states, and properties. This document is directed primarily to Web application developers, but the guidance is also useful for user agent and assistive technology developers. ... After a brief Read Me First section, the guide begins with ARIA implementation patterns for common widgets that both enumerate expected behaviors and demonstrate those behaviors with working code. The implementation patterns and examples refer to detailed explanations of supporting concepts in subsequent guidance sections. The guidance sections cover more general topics such as use of ARIA landmarks, practices for keyboard interfaces, grid and table properties, and the effects of role`presentation`. ... #### Principle 1: A role is a promise ... ``` < ... ="button">Place Order</div> ...

Unlike HTML input elements, ARIA roles do not cause browsers to provide keyboard behaviors or styling. ... of that role ... order and empties the shopping cart ... One of the objectives of this guide is to define expected behaviors for each ARIA role. ... ``` <button aria-pressed="false">Mute</button> ``` ... This section demonstrates how to make common rich internet application patterns and widgets accessible by applying WAI-ARIA roles, states, and properties and implementing keyboard support. ... accessible name is a short string, typically ... 1 to 3 words, that authors associate with an element to provide users of assistive technologies with a label for the element. For example, an input field might have an accessible name of "User ID" or a button might be named "Submit". ... Both the WAI-ARIA specification and WCAG require all focusable, interactive elements to have an accessible name. In addition dialogs and some structural containers, such as tables and regions, are required to have a name. Many other elements can be named, but whether a name will enhance the accessible experience is determined by various characteristics of the surrounding context. Finally, there are some elements where providing an accessible name is technically possible but not advisable. The Accessible Name Guidance by Role section lists naming requirements and guidelines for every ARIA role. ... An accessible description is also an author-provided string that is rendered by assistive technologies. Authors supply a description when there is a need to associate additional information with an element, such as instructions or format requirements for an input field. ... Assistive technologies present names differently from descriptions. For instance, screen readers typically announce the name and role of an element first, e.g., a button named Mute Conversationcould be spoken as Mute Conversation button. If an element has a state, it could be announced either before or after the name and role; after name and role is the typical default. For example, a switch button named Mute Conversation in the off state could be announced as Mute Conversation switch button off. Because descriptions are optional strings that are usually significantly longer than names, they are presented last, sometimes after a slight delay. For example, Mute Conversation Switch button off, Silences alerts and notifications about activity in this conversation. To reduce verbosity, some screen readers do not announce descriptions by default but instead inform users of their presence so that users can press a key that will announce the description. ... | button | Required Only If C…[truncated] <title>Providing Accessible Names and Descriptions | APG | WAI | W3C</title> https://www.w3.org/WAI/ARIA/apg/practices/names-and-descriptions/ Both the WAI-ARIA specification and WCAG require all focusable, interactive elements to have an accessible name.

If an interactive element, such as an input field or button, does not have a visually persistent text label, consider adjusting the design to include one. In addition to serving as a more robust source for an accessible name, visible text labels enhance accessibility for many people with disabilities who do not use assistive technologies that present invisible accessible names. In most circumstances, visible text labels also make the user interface easier to understand for all users. ... When assistive technologies render an element that gets its accessible name from its content, ... as a link or button, the accessible name is the only content the user ... for that element. This is in contrast to other elements, such as text fields or tables, where the accessible name is a label that is presented in addition to the value or content of the element.

This section describes the principles and methods for making the functionality of a web page that includes ARIA widgets, such as menus and grids, as well as interactive components, such as toolbars and dialogs, operable with a keyboard. Along with the basics of focus management, this section offers guidance toward the objective of providing experiences to people who rely on a keyboard that are as efficient and enjoyable as the experiences available to others. ... A primary keyboard navigation convention common across all platforms is that the tab and shift + tab keys move focus from one UI component to another while other keys, primarily the arrow keys, move focus inside of components that include multiple focusable elements. The path that the focus follows when pressing the tab key is known as the tab sequence or tab ring. ... When selection does not follow focus, the user changes which element is selected by pressing the Enter or Space key. ... As explained in section Fundamental Keyboard Navigation Conventions, all interactive UI components need to be reachable via the keyboard. This is best achieved by either including them in the tab sequence or by making them accessible from a component that is in the tab sequence, e.g., as part of a composite component. This section addresses building and managing the tab sequence, and subsequent sections cover making focusable elements that are contained within components keyboard accessible. ... As described in section Fundamental Keyboard Navigation Conventions, the tab sequence should include only one focusable element of a composite UI component. Once a composite contains focus, keys other than Tab and Shift + Tab enable the user to move focus among its focusable elements. Authors are free to choose which keys move focus inside of a composite, but they are strongly advised to use the same key bindings as similar components in common GUI operating systems as demonstrated in APG Patterns. ... - The selected element. Or, if there is no selected element, the first element. Widgets where this pattern is commonly implemented include radio groups, tabs, list boxes, and trees. Note: For radio groups, this pattern is referring to the checked radio button; the selected state is not supported for radio buttons. ... . Components that typically follow this pattern include menubars and toolbars. ... If a component container has an ARIA role that supports the aria-activedescendant property, it is not necessary to manipulate the`tabindex` attribute and move DOM focus among focusable elements within the container. Instead, only the container element needs to be included in the tab sequence. When the container has DOM focus, the value of`aria-activedescendant` on the container tells assistive technologies which element is active within the widget. Assistive technologies will consider the element referred to as active to be the focused element even though DOM focus is on the element that has the`aria-activedescendant` property. And, when the value of`aria-activedescendant` is changed, assistive technologies will receive focus change events equivalent to those received when DOM focus actually moves. ... - It has` ... DOM descendant of the focused ... -activedescendant` and ... This guidance focuses specifically on keyboard interaction. However, authors also need to consider pointer interactions, such as mouse clicks and touchscreen taps. When a component is clicked/tapped, authors should take the same steps to set the correct`tabindex` or`aria-activedescendant` for the element, in the same way that they would for keyboard navigation. Otherwise, this could lead to a confusing experience for users that switch between pointer and keyboard navigation, as it will lead to a mismatch. ... Bro...

Expose the reorder instructions to assistive technology.

This focusable <span> has no control role. Its title is not a reliable accessible description, so screen-reader users may not learn that it can reorder columns with Alt+Left and Alt+Right. Do not add role="button" alone. The WAI-ARIA button pattern requires Enter and Space activation, but this element has no handlers for those keys. Keep the draggable-item pattern and expose a localized description through aria-describedby or the accessible name. Use a native or ARIA button only if Enter and Space behavior is implemented.

draggable comparison-column span associated with startComparisonColumnDrag,
endComparisonColumnDrag, and moveComparisonColumn so assistive technology
receives a localized description of the Alt+Left and Alt+Right reorder
instructions via aria-describedby or the accessible name. Preserve the existing
