# Account Settings Form — Run Notes

## Benchmark identity

- Agent name: Luna
- Reasoning level: xhigh
- Skill mode: new-skill
- Active frontend skill: frontend-art-direction
- Exact output directory: `<LOCAL_SAMPLE_ROOT>/luna-xhigh/new-skill/03-settings-form`

## Files created

- `index.html`
- `styles.css`
- `script.js`
- `RUN.md`

External dependencies: None. The form uses only local HTML, CSS, and JavaScript and runs by opening `index.html`.

## Verification performed

- Reviewed the state model for competing failure modes before editing: validation is separated from dirty tracking; failed saves do not overwrite the saved snapshot; cancel restores the saved snapshot; saving disables editable controls; and `beforeunload` warns only while unsaved changes exist.
- Verified the semantic form structure, explicit labels, native text/select/checkbox controls, `aria-describedby` field hints and errors, `aria-invalid` changes, status/live regions, logical DOM tab order, and visible `:focus-visible` styles by source inspection.
- Verified required-field validation and invalid-email validation paths in `script.js`; the first invalid field is focused and the adjacent error is exposed.
- Verified dirty-state detection for text, select, and notification controls; cancel/reset restores the last saved snapshot and clears validation/feedback.
- Verified simulated saving state: form has `aria-busy`, editable fieldsets and save-outcome control are disabled, the save button changes to `Saving…`, and the saving note/spinner is announced.
- Verified success and failure save branches: success updates the saved snapshot and clears dirty state; failure preserves dirty state and gives retry guidance.
- Verified notification toggles update visible “On”/“Off” text, so state is not communicated by color alone.
- Verified responsive rules for desktop, narrow desktop, and mobile widths; mobile settings navigation can scroll horizontally and the content layout stacks without page-level horizontal overflow.
- Verified `prefers-reduced-motion: reduce` disables transitions/animations and smooth scrolling.
- Verified no remote URLs, external fonts, image requests, package managers, or build tools are required.
- Exercised the live page in local headless Chrome at desktop and mobile viewport sizes: the page loaded from `file:///`, required and invalid-email paths announced correctly, save transitions completed, Tab order reached the form controls/actions, and desktop/mobile screenshots were visually inspected. Temporary screenshots and browser profiles were removed afterward.

## Triggering simulated save outcomes

1. Open the `Evaluation controls` disclosure at the bottom of the page.
2. Choose `Successful save` (default), change any field, and press `Save changes` to see the saving state followed by success.
3. Choose `Failed save`, change any field, and press `Save changes` to see the saving state followed by failure. The changed values remain dirty so the save can be retried.
4. A failed outcome can also be preselected by opening `index.html?save=failure` (or `?save=fail`), then changing a field and saving.

## Verification results

Result: implementation complete. The standalone form paths are wired and the static, live-browser, responsive, and visual checks above passed.

## Known limitations

- Save success/failure is intentionally simulated with a short local timer; no server or persistence layer is included.
- The browser’s native `beforeunload` confirmation is controlled by the browser and cannot be customized beyond the standard warning behavior.
- The narrow settings navigation contains the two in-scope anchors only; it does not implement unrelated settings pages.
