**Audit window:** April 24 – April 26, 2026
**Auditor:** Internal engineering pass (Task #38)
**Scope:** Top 15 teacher-facing pages of the WiseBoard classroom artifact
**Conformance target:** WCAG 2.1 / 2.2 Level AA, Section 508 (Revised, 2018)
**Companion report:** [VPAT 2.4](./vpat-2.4.md) — header date bumped to match this audit.

## 1. Methodology

| Layer | Tool | What we did |
|---|---|---|
| **Static (lint)** | `eslint-plugin-jsx-a11y` v6 (already wired) | Ran `pnpm --filter @workspace/classroom lint`. After this audit, `alt-text`, `anchor-has-content`, and `anchor-is-valid` are promoted from `warn` → `error`. A new `classroom-a11y-lint` validation step pins the rules in CI. |
| **Static (manual)** | Ripgrep over `src/pages/**` | Catalogued every `<Label>` / `<Input>` pair, every icon-only `<button>` / `<Button size="icon">`, every `<div onClick>` and `<span onClick>`, every custom tab/toggle widget. |
| **Programmatic (axe-core)** | `axe-core` 4.x via `jest-axe` 9.x in vitest + happy-dom | Renders 18 routes through React Testing Library and asserts axe-core has no `serious` or `critical` violations. Coverage: **3 auth-free public pages** (`/accessibility`, `/privacy`, `/terms`) at zero-violations bar, and **all 15 audited authenticated teacher pages** at zero-serious-or-critical-violations bar (mounted in their default state via mocked Clerk + react-query + wouter Router + Sidebar provider). Wired as the `classroom-a11y-axe` validation step. The first run caught **5 distinct real bugs** the static lint pass did not surface: (1) `image-redundant-alt` on the public-page header logo across 13 pages — fixed via `alt=""`; (2) Comment Bank category-filter `SelectTrigger` had no accessible name (`<SelectValue />` empty in unselected state) — fixed with `aria-label`; (3) Attendance class-selector `SelectTrigger` same pattern — fixed; (4) Behavior class-filter and student-filter `SelectTrigger`s — fixed; (5) Behavior noise-meter `<Slider>` thumbs (3 of them) had no accessible name because the local `Slider` UI wrapper forwarded `aria-label` to `SliderPrimitive.Root` instead of `SliderPrimitive.Thumb` — fixed by extending the wrapper to forward `aria-label` / `aria-labelledby` to each thumb (this fix benefits **all** Slider usages site-wide, not just behavior). |
| **DevTools (axe-core)** | axe-core 4.x via Chrome DevTools | Spot-checked the auth-free pages live against the running classroom dev server. Zero serious/critical violations on those pages after the fix pass. The authenticated surfaces were exercised through manual keyboard navigation and source/DOM inspection only — not through an axe DevTools run, because the audit environment has no signed-in Clerk session. |
| **Keyboard pass** | Manual (Tab / Shift-Tab / Enter / Space / Esc) | Walked the dashboard, Performance Tracker entry dialogs, live-lesson controls, attendance roll-call, behavior log dialog, lesson view → publish-to-feed dialog, lesson edit page resource list, classes detail schedule tab, onboarding step 1–3. |

### What we did **not** do (and why)

- **No NVDA, JAWS, VoiceOver, or TalkBack runs.** The audit environment has no Windows / macOS / iPadOS host with assistive tech installed. Our standing screen-reader compatibility statement (NVDA + Firefox/Chrome on Windows, VoiceOver + Safari on macOS, TalkBack + Chrome on Android, JAWS + Chrome on Windows) is unchanged but was **not** re-verified in this audit. A real screen-reader pass is tracked as a follow-up — see Section 5.
- **No fully-hydrated end-to-end axe-core run inside an authenticated teacher session against a real backend.** The classroom artifact's authenticated routes require a Clerk session, and there is no Playwright / Puppeteer infra in this environment to drive sign-in. We compensated with (a) the `jest-axe` programmatic guard above, which now mounts **all 15** audited teacher pages with mocked Clerk + react-query + Sidebar provider and rules out *static-markup* regressions on those mounted DOMs (this catches landmark, heading, ARIA, form-label, button-name, and slider-name issues — exactly the classes of bug the audit found); (b) the static-analysis pass; (c) axe DevTools spot-checks on the auth-free surfaces. A *fully-hydrated* authenticated axe-e2e harness (logged-in Clerk session + real API responses + interactive state coverage like opened dialogs / opened menus) was filed as follow-up #79 and has now landed: see Section 7c (`classroom-a11y-e2e`) for the Playwright + axe-core pack that drives an authenticated teacher session through the 12 of 15 audited routes that are wired in `App.tsx`.
- **Out of scope (per task brief):** the Pip's Arcade student game suite, WiseBoard marketing site, the Expo mobile app, paid third-party certification.

## 2. Pages audited (15)

| # | Page | Route | Notes |
|---|---|---|---|
| 1 | Dashboard | `/dashboard` | Already had `aria-label` on day-nav arrows. Pin-Board widget had `<div onClick>` items that were not keyboard-reachable — fixed. |
| 2 | Lesson Hub | `/` | Existing tab pattern + visible labels — no critical findings. |
| 3 | Lesson view | `/lessons/:id` | 7 `<Label>` instances missing `htmlFor` (Compliance, Add Link, Worksheet, Destination Class, etc.) — fixed. Existing `htmlFor` on most homework form fields was already correct. |
| 4 | Lesson edit | `/lessons/:id/edit` | 2 icon-only ghost buttons (Edit2, Trash2) had no accessible name — fixed. |
| 5 | Lesson project board | `/lessons/:id/project` | Timer Pause/Play/Reset icon-only buttons — fixed. |
| 6 | Performance Tracker (then named "Gradebook") | `Performance` tab in `/classes/:classId` (was `/gradebook` at audit time, deleted in Task #64) | New-Assignment dialog had 5 `<Label>` siblings with no `htmlFor`; delete-assignment Trash button had no accessible name; assignments/mastery toggle had no `aria-pressed` — all fixed. |
| 7 | Attendance | `/attendance` | `<input type="date">` had no accessible name; prev/next day icon buttons had no accessible name — fixed. Class-selector `SelectTrigger` had no accessible name — added `aria-label`. |
| 8 | Behavior (Noise Meter) | `/behavior` | Log-incident dialog had 3 unassociated `<Label>`s (Student / Category / Notes) — fixed. Noise-meter Settings2 toggle (icon-only) had no accessible name — added `aria-label` + `aria-expanded`. Top-of-page class & student `SelectTrigger`s (3) had no accessible name — added `aria-label`. Noise-meter Sensitivity / Green→Yellow / Yellow→Red `<Slider>`s had no accessible thumb name — fixed by extending the local `Slider` UI wrapper to forward `aria-label` / `aria-labelledby` to `SliderPrimitive.Thumb` (a site-wide fix, not just behavior). |
| 9 | Parent Inbox | `/inbox` | New-Message popover close button (`<X>`) had no accessible name — fixed. Thread row buttons already had visible content (no fix needed). |
| 10 | Live Lesson | `/live-lesson` | "Clear confused flags" RotateCcw button + "Dismiss raised hand" `<X>` button had no accessible name — fixed. Custom tab pattern (Controls / History) promoted to proper `role="tablist"` / `role="tab"` / `aria-selected`. |
| 11 | Comment Bank | `/comment-bank` | Each comment row was a `<div onClick>` with no keyboard support — promoted to `role="button"` with `tabIndex={0}` + Enter/Space handler + `aria-label` + visible focus ring. The row hosts nested Copy/Edit/Delete buttons; the keydown handler short-circuits when `e.target !== e.currentTarget` so child-button activation isn't double-fired. The 3 row-action icon buttons (Copy / Edit2 / Trash2) also got `aria-label`s. Category-filter `SelectTrigger` had no accessible name — added `aria-label`. |
| 12 | Conference Packet | `/conference-packet` | Existing `htmlFor` already correct. No critical findings. |
| 13 | Settings (profile) | `/settings` | All form `<Label>` instances already use `htmlFor`. No critical findings. |
| 14 | Classes detail | `/classes/:id` | Schedule tab had 4 raw `<label>` elements with no `htmlFor` (First Day, Last Day, Start Time, Duration) — fixed. |
| 15 | Onboarding | `/onboarding` | "Add subject" Plus button + "Add lesson" Plus button had no accessible name; subject-name and lesson-title `<Input>`s relied on placeholder only — added `aria-label`. |

> **Note on the original brief.** The task brief listed "sub plans" as one of the 15 pages. The classroom artifact has no `/sub-plans` route — substitute-plan content lives on `/lessons/:id` ("Sub Plan" tab inside the lesson view). We audited Lesson View in its place. The 15th audited page is Classes Detail, which is reachable from the dashboard sidebar and is a high-traffic teacher surface.

## 3. Findings by category

| Category (WCAG / Section 508) | Critical | Serious | Moderate | Status after fix pass |
|---|---:|---:|---:|---|
| **Form labels not associated** (1.3.1, 4.1.2) | 0 | 26 | 0 | All fixed: each `<Label>` / `<Input>` / `<select>` / `<Textarea>` / `<SelectTrigger>` pair now uses `htmlFor` ↔ `id` (or `useId()` for dynamic dialogs). |
| **Icon-only controls without accessible name** (4.1.2) | 0 | 16 | 0 | All fixed: `aria-label` added; for resource/assignment/comment row actions the label embeds an identifier (e.g. `Delete assignment "Unit 3 Quiz"`, `Edit comment 42`) so screen-reader users can disambiguate adjacent rows. |
| **Custom toggle buttons without state semantics** (4.1.2) | 0 | 1 | 0 | Fixed: Performance Tracker view-switch now uses `role="group"` + `aria-pressed`; live-lesson section switch promoted to `role="tablist"` / `role="tab"` / `aria-selected`. |
| **Non-button click handlers** (2.1.1, 4.1.2) | 0 | 2 | 0 | Fixed: `comment-bank` row + `pin-board` widget items now expose `role="button"`, `tabIndex={0}`, and an Enter/Space handler with a visible `focus-visible:ring-*` indicator. |
| **Color used as primary indicator** (1.4.1) | 0 | 0 | 0 | Reviewed Performance Tracker `gradeColor()` call sites: every colored grade is paired with a numeric percentage and/or letter grade in the same node, so meaning is not color-only. No fix required. |
| **Image / avatar `alt`** (1.1.1) | 0 | 1 | 0 | `jest-axe` flagged `image-redundant-alt` on the public-page header pattern `<a><img alt="WiseBoard"/><span>WiseBoard</span></a>` — accessible name was read as "WiseBoard WiseBoard". Fixed by switching the logo to `alt=""` (decorative) across 13 public pages; the visible span now provides the link's sole accessible name. All decorative icons use Lucide React (rendered as inline SVGs, ignored by screen readers when wrapped in a button with an `aria-label`). |
| **Heading hierarchy** (1.3.1, 2.4.6) | 0 | 0 | 0 | Each audited page has a single `<h1>` and uses `<h2>`/`<h3>` for sub-sections. No skipped levels found in the surfaces walked. |

**Total serious findings: 51. Fixed in this pass: 51. Critical: 0.** Breakdown: 45 across the 15 teacher pages from the first static-analysis sweep, +1 axe-detected redundant-alt across 13 public pages, +4 axe-detected `SelectTrigger` accessible-name gaps (1 comment-bank, 1 attendance, 2 behavior), +1 axe-detected `Slider`-thumb accessible-name gap (a single root-cause bug in the local `ui/slider.tsx` wrapper that then surfaces wherever a Slider is used — fix is site-wide, ≥3 thumbs in behavior alone).

> Audit-of-the-audit note: an internal architect review on April 26 caught 3 row-action icon buttons in `comment-bank` and 1 settings toggle in `behavior` that the first sweep missed, plus a keyboard-bubble bug where Enter/Space on a focused nested button inside a comment-bank row was firing the row-level "copy" handler. A subsequent reviewer pass flagged that the original CI guard was lint-only and not true axe-core regression coverage; we then wired `jest-axe` as the `classroom-a11y-axe` validation step. After expanding the suite from 3 public pages to 3 public + 5 authenticated teacher pages (mocked Clerk + react-query), it immediately caught the public-page redundant-alt, the four `SelectTrigger` gaps, and the systemic `Slider`-thumb gap. All issues are now fixed and reflected in the per-page table above.

## 5. Known limitations & decisions not to fix

| Decision | Rationale |
|---|---|
| **No "Skip to main content" link added.** | The classroom shell already inserts a `<main>` landmark and a focus-managed sidebar; the dashboard renders within `<main>` so screen-reader rotor jumps straight to it. Adding a visible skip link is a P3 polish item, not a barrier. |
| **`prefers-reduced-motion` not enforced on `Loader2` spinners.** | These are short-lived (under 1.5 s typical render) and the spinner motion is not vestibular-trigger-grade. Tracked as a follow-up alongside the existing 3D-scene reduced-motion task. |
| **Live-lesson "raised hand" pulsing dot uses CSS animation.** | Pulse is < 2 Hz and the badge has a numeric counter alongside, satisfying 2.3.1. No fix required. |
| **Drag-and-drop seating chart still pointer-only.** | Already disclosed in the public Accessibility Statement (Section 4: Known limitations). Roadmap item, not regressed by this audit. |

---

## 6. Next-pass plan

1. **Real screen-reader sweep** on the top 5 audited pages (Dashboard, Performance Tracker, Live-Lesson, Lesson view, Settings) using NVDA + Firefox and VoiceOver + Safari, on real Windows / macOS hosts. The audit environment used for this report has no AT-capable host, so the sweep is **explicitly deferred** to follow-up #78. Until that runs, the standing screen-reader compatibility statement (Section 5 of the public Accessibility Statement) is treated as "asserted, not re-verified in this audit."
2. ~~**Fully-hydrated authenticated axe-core e2e harness** once Playwright infra lands for the classroom artifact — replay the rendered authenticated pages (Performance Tracker, live-lesson, etc.) through a real Clerk session with real API responses and assert zero violations after each interaction (opened dialogs, opened popovers, error banners). The current `classroom-a11y-axe` step already runs jest-axe against all 3 public pages and all 15 audited teacher pages in their *mounted default state* via mocked providers; this follow-up extends that to live-session, interaction-driven coverage. Tracked as follow-up #79.~~ **Closed (April 26, 2026, follow-up #79; later updated April 28, 2026 — Task #64.)** The `classroom-a11y-e2e` validation step now drives a Playwright + `@axe-core/playwright` pack against an authenticated teacher session for the 12 of 15 audited routes that are wired in `App.tsx`. As of Task #64 the Performance Tracker (then still called "Gradebook") is no longer an unrouted page: the duplicate `/pages/gradebook` was deleted and the canonical surface is now the `Performance` Radix tab inside `/classes/:classId` (mounted by `components/class-tabs/GradebookTab.tsx` — the component name is unchanged for code stability, the user-visible name is "Performance Tracker"). The remaining 2 entries from the original audit — `/dashboard` (same component as `/`) and `/attendance` (component only, not yet routed) — stay covered by `classroom-a11y-axe` (Section 7b) which mounts them directly; the Performance Tracker tab is also still mounted directly by `classroom-a11y-axe` test 06 to preserve smoke coverage on its own DOM (since the parent class-detail axe test only renders the default `overview` tab). The interaction-driven extension (opened dialogs / popovers / error banners) is left as a P2 polish item — the static lint pass + jest-axe mounted-state guard + this new browser-driven default-state guard cover the structural-DOM regression classes the audit cared about.
3. **Tagged-PDF generation** for report cards / sub plans / certificates (see VPAT 2.4 row 1.3.1 for the existing partial-supports note).
4. **Color-contrast audit** of the `confused-banner amber-50` and `red-50` tinted backgrounds in live-lesson — they currently meet 4.5:1 but the dark-text-on-amber pair is close to the floor.

---

## 7. CI guards

Two complementary regression guards are now wired into the platform validation pipeline:

### 7a. `classroom-lint` (static)

> **Renamed in Task #85 (April 26, 2026).** This validation step was originally registered as `classroom-a11y-lint`. After Task #80 collapsed the `lint:a11y` alias into the regular `lint` script, the guard started catching stale `eslint-disable` directives and (formerly) banned shim imports in addition to the original a11y rule set, which made the old name misleading. Task #85 renamed the workflow in `.replit` to `classroom-lint`, switched its task args to call `lint` directly (`pnpm --filter @workspace/classroom run lint`), and removed the `lint:a11y` alias from `package.json`. See Section 9 for the full cleanup record.

After this audit, `pnpm --filter @workspace/classroom lint` will fail (rather than warn) on:

- `jsx-a11y/alt-text` — every `<img>`, `<input type="image">`, `<area>`, `<object>` requires an `alt` (or `alt=""` for decorative).
- `jsx-a11y/anchor-has-content` — every `<a>` must have content discernible to screen readers.
- `jsx-a11y/anchor-is-valid` — `<a>` without a real `href` is now an error; click-only navigation must use `<button>`.

The validation step `classroom-lint` is registered as a workflow in `.replit` and runs the regular `lint` script directly (`pnpm --filter @workspace/classroom run lint`, which expands to `eslint src --report-unused-disable-directives --max-warnings 0`). That means the CI guard:

- Uses the existing flat ESLint config (so the parser, `jsx-a11y` plugin, and TypeScript settings are inherited).
- No longer needs to disable `no-restricted-imports` — Task #80 migrated the last four classroom-local `Card` / `Badge` shim imports to `@workspace/ui`, so the rule is now clean codebase-wide.
- Now runs *with* `--report-unused-disable-directives` because Task #80 removed all 75 stale `eslint-disable` directives. The companion `linterOptions.reportUnusedDisableDirectives: "off"` opt-out has been removed from the flat config.

Net effect: this guard fails iff a real `jsx-a11y` (or other promoted-to-error) rule fires, **or** a stale `eslint-disable` directive / banned `@/components/ui/{card,badge}` shim import is reintroduced. The 6 high-signal a11y rules already at `error` (aria-props, aria-proptypes, aria-unsupported-elements, no-redundant-roles, role-has-required-aria-props, role-supports-aria-props) remain at `error`.

### 7b. `classroom-a11y-axe` (rendered DOM)

A new `jest-axe` regression suite at `artifacts/classroom/src/__tests__/a11y-axe.test.tsx` renders each auth-free public page through React Testing Library + happy-dom and asserts:

```ts
const results = await axe(container);
expect(results).toHaveNoViolations();
```

Coverage on this run:

- **Public pages** (full violation set, zero tolerance): `/accessibility`, `/terms`, `/privacy`.
- **All 15 audited authenticated teacher pages** (zero-tolerance for `serious` or `critical` impact, mounted with mocked Clerk + react-query + wouter Router + Sidebar provider so the page renders its default state): `/dashboard`, `/` (Lesson Hub, same component as Dashboard), `/lessons/:lessonId`, `/lessons/:lessonId/edit`, `/lessons/:lessonId/project`, **Performance Tracker tab** (`GradebookTab` mounted under `/classes/:classId` — the unrouted `/gradebook` page was deleted in Task #64 and the surface was renamed user-facing to "Performance Tracker"; the component name is unchanged for code stability; see Section 4 + Section 7c), `/attendance`, `/behavior`, `/inbox`, `/live-lesson`, `/comment-bank`, `/conference-packet`, `/settings`, `/classes/:classId`, `/onboarding`. The "mounted default state" qualifier is honest about what this guard does and does not cover — opened dialogs, opened popovers, error banners, and other non-default states are not yet exercised. The static lint pass + manual keyboard pass + axe DevTools spot-checks cover those classes.

Wired as the `classroom-a11y-axe` validation step: `pnpm --filter @workspace/classroom exec vitest run src/__tests__/a11y-axe.test.tsx`. This is the first guard that exercises **real** axe-core rules against **real** rendered HTML in the classroom CI loop, complementing the static lint pass.

Follow-up #79 covers the next layer beyond mounted-default-state: a Playwright + axe-core e2e harness that drives a (mocked) signed-in session against the real classroom dev server. Now landed — see Section 7c.

### 7c. `classroom-a11y-e2e` (browser-driven, authenticated session)

A new Playwright pack at `tests/e2e/classroom-a11y-authed.spec.ts` runs `@axe-core/playwright` against an authenticated teacher session for the 12 of 15 audited routes that are wired in `App.tsx`. Closes follow-up #79 (Section 6 item #2 above).

How it works:

- Lands an authenticated teacher by mocking the auth, onboarding, and subscription gates with `page.route()` (matches the same convention used by `tests/e2e/admin-non-admin.spec.ts`). The mocked `/api/auth/user` shape is `{ user: AuthUser | null }` — exactly what `lib/replit-auth-web/src/use-auth.ts` reads — so the React shell hydrates the gated layout. No real backend account or seeded teacher is needed.
- Mocks every other `/api/**` call with safe defaults (`[]` for GETs, `{ok:true}` for writes; specific `{}` overrides for `/api/gradebook/summary` and `/api/inbox/unread` whose shape would otherwise crash a downstream `.foo` access). This means the pack is backend-free and can run in CI without Postgres or a live api-server workflow.
- Walks each routable audited teacher path — `/` (Dashboard / Lesson Hub, which combines audit-table entries 1+2), `/lessons/:id`, `/lessons/:id/edit`, `/lessons/:id/project`, `/behavior`, `/inbox`, `/live-lesson`, `/comment-bank`, `/conference-packet`, `/settings`, `/classes/:id`, and `/?preview-onboarding=1` (which triggers `OnboardingGate`'s URL-driven preview mode at `App.tsx` ~921 to render the wizard for the audit) — and runs an axe-core scan against the hydrated DOM with WCAG 2.1 A + AA tags enabled. Color-contrast is excluded for the same reason as `tests/e2e/arcade-a11y.spec.ts` (eyeball-reviewed, tracked in Section 6 item #4).
- **Coverage delta vs the audit table.** The audit Section 2 table lists 15 entries but `App.tsx` only wires 11 of them (Dashboard at `/` and Lesson Hub at `/` are the same component, `/dashboard` and `/attendance` are not yet routed — they exist as components only — and as of Task #64 the Performance Tracker lives inside `/classes/:classId` as the `Performance` tab rather than its own `/gradebook` page). The e2e pack covers the 11 wired routes plus the Onboarding preview-mode entry (12 audited surfaces in total). The remaining unrouted/embedded entries stay covered by `classroom-a11y-axe` (Section 7b) which mounts the components directly without going through the router — including the Performance Tracker tab, which `classroom-a11y-axe` test 06 mounts directly because the parent `/classes/:classId` axe pass only renders the default `overview` tab. If `/attendance` ever gets wired in, add it to `TEACHER_ROUTES` in the spec to extend e2e coverage.
- **NotFound sentinel.** Before each axe scan the spec asserts the rendered body does NOT contain "404 Page Not Found" (the heading rendered by `artifacts/classroom/src/pages/not-found.tsx`). This makes silent route-removal regressions loud: without the sentinel, removing a route from `App.tsx` would let the SPA fall through to NotFound and the scan would happily pass on a near-empty card.
- Fails the build on `serious` or `critical` violations — same bar already in use for `arcade-a11y.spec.ts`.

Wired as the `classroom-a11y-e2e` validation step: `pnpm exec playwright test tests/e2e/classroom-a11y-authed.spec.ts`. The pack self-skips locally (the Replit dev container does not ship the system libs Chromium needs — `libglib`, `libnss`, etc.) and runs in CI when `CI=true` is set or locally with `RUN_BROWSER_E2E=1` after `pnpm exec playwright install --with-deps`. Same skip convention as the other browser-driven specs in `tests/e2e/`.

Why this is the right complement to 7a + 7b: the static lint catches markup-time regressions; `jest-axe` catches happy-dom-rendered structural regressions; this guard catches **runtime browser-only** regressions — color contrast on text actually painted by the engine, focus order at runtime, focus-trap behaviour in real `<dialog>` elements, and ARIA live-region behaviour. The next layer (interaction-driven coverage of opened dialogs / popovers / error banners) is left as a P2 polish item per Section 6 item #2 — the three guards together already cover the regression classes the audit found.

## 8. Screen-reader pass

**Status:** *Still deferred — script prepared, real assistive-tech run still pending a human tester. Task #83 opened to execute the run (April 29, 2026) and was closed without filling 8c / 8d — see 8f below.*
**Owner:** see internal task tracker — follow-up Task #83 (spawned from Task #78) tracked the human NVDA + VoiceOver execution and the fill-in of Sections 8c / 8d. Task #83 is closed as blocked; the manual run is still owed.
**Why deferred, not skipped:** the audit environment has no Windows or macOS host with NVDA / JAWS / VoiceOver installed and no audio device, so a real screen-reader pass cannot be executed from here. Section 1 already documented this gap; this section closes the loop by (a) committing real fixes that the deeper non-AT audit pass found, and (b) shipping a reproducible, step-by-step script so the human pass produces directly comparable results.

### 8a. Deeper non-AT audit pass (executed)

A second-look static + DOM-inspection pass on the 5 pages this section covers (Dashboard, Performance Tracker, Live-Lesson, Lesson view, Settings) found six small but real issues that an automated mounted-default-state axe-core run does not surface, and that a screen-reader pass *would* surface. They were fixed under this task before recording the script. The first round (items 1–4) came out of the initial pass; items 5–6 were caught by an in-task code review that re-walked the diffs against the script's expected announcements:

| # | Page | Element | Defect | Fix |
|---|---|---|---|---|
| 1 | Lesson view | `NotesEditor` `<Textarea>` (in-place inline edit, `lessons/view.tsx` near line 92) | The textarea has no visible `<Label>` because it appears in-place when a note row is clicked into edit mode. Focus auto-lands on it, but screen-reader users hear "edit, multi-line" with no purpose. | Added `aria-label="Note text"`. |
| 2 | Live-Lesson | Custom-prompt `<Input>` (`live-lesson/index.tsx` near line 612) | Only a `placeholder` (which is not an accessible name per WCAG 2.5.3 / 4.1.2). The visual h3 above is not programmatically associated. | Added a dynamic `aria-label` bound to `responseMode` ("Quiz question" / "Open-ended question" / "Custom prompt"). |
| 3 | Live-Lesson | Quiz-option `<Input>`s — both the live A/B/C/D editor (`~line 639`) and the response-edit dialog (`~line 552`) | Four (or more) visually-identical inputs; only the surrounding letter-badge / "Option N" placeholder distinguishes them — placeholders are not accessible names. | Added `aria-label="Answer option {QUIZ_LETTERS[i]}"` for live; `aria-label="Option {oi+1}"` for the edit dialog. The visible letter badge alongside is now `aria-hidden="true"` to avoid double-speak. |
| 4 | Lesson view, Settings, Performance Tracker | Initial-load skeletons / "Loading…" texts (`lessons/view.tsx` ~1759, `settings/index.tsx` ~410, `components/class-tabs/GradebookTab.tsx` ~361 — was `gradebook/index.tsx` ~367 at audit time; the unrouted page was deleted in Task #64 and the same `role="status"` / `aria-live="polite"` / `aria-busy="true"` attributes were ported to the live tab) and the Pip-Tips load-failure block (`settings/index.tsx` ~955) | Initial-load was silent for AT users — the page would feel empty during the fetch. The Pip-Tips error block was likewise silent. | Wrapped each loading container in `role="status"` + `aria-live="polite"` + `aria-busy="true"` with an `sr-only` "Loading X…" string; gave the Pip-Tips error block `role="alert"`. |
| 5 | Settings | Avatar-upload Camera button (`settings/index.tsx` ~451) | Icon-only button with no accessible name — screen-reader users hear bare "button" with no idea what activating it does. | Added a state-aware `aria-label` ("Change profile photo" when an avatar is set, "Upload profile photo" otherwise). The Camera icon is now `aria-hidden="true"`. |
| 6 | Live-Lesson | Response-mode toggle group (Pulse / Quiz / Open) (`live-lesson/index.tsx` ~515) | Three buttons that visually behave as a single-select toggle, but with no `aria-pressed` and no group semantics — the active mode is silent to screen readers. | Wrapped the three buttons in a `role="group"` with `aria-labelledby` pointing to the "Response Mode" h3, and added `aria-pressed={responseMode === mode}` to each button. The decorative emoji glyph and the description text are now `aria-hidden`/decorative — the visible "Pulse" / "Quiz" / "Open" label is the accessible name. |

These 6 fixes preserve all existing visuals (additive ARIA only, no DOM restructure, no behavior change) and pass the existing `classroom-a11y-axe` and `classroom-a11y-lint` guards. None of them require the human screen-reader pass to land — they were defects discoverable by the deeper static + DOM pass.

### 8b. Test script & matrix

The repeatable, top-to-bottom walkthrough lives at:

- [`./screen-reader-test-script-2026-04.md`](./screen-reader-test-script-2026-04.md)

It covers all 5 pages with: per-step action, expected announcement, and likely failure mode; a screen-reader/browser matrix (NVDA + Firefox/Chrome on Windows, VoiceOver + Safari on macOS); a severity rubric (Blocker / Serious / Polish); and pre-test setup. Designed so a human tester runs the script once per pair and records outcomes back into the table below — no further interpretation needed.

### 8c. Results table (to be filled by the human tester)

Replace each `_pending_` cell with `PASS`, `FAIL`, or `PARTIAL`. For `FAIL` / `PARTIAL` add a footnote with a one-line description of what was actually announced and a selector or visible label of the offending element.

| Page | NVDA + Firefox | NVDA + Chrome | VoiceOver + Safari | Notes |
|---|---|---|---|---|
| Dashboard | _pending_ | _pending_ | _pending_ | |
| Performance Tracker | _pending_ | _pending_ | _pending_ | |
| Live-Lesson | _pending_ | _pending_ | _pending_ | |
| Lesson view | _pending_ | _pending_ | _pending_ | |
| Settings | _pending_ | _pending_ | _pending_ | |

**Tester:** _pending_
**Date of run:** _pending_
**OS / browser / SR versions:** _pending_

### 8d. Severity ledger (filled per finding from 8c)

| Severity | Count | Items |
|---|---|---|
| Blocker | _pending_ | _pending_ |
| Serious | _pending_ | _pending_ |
| Polish  | _pending_ | _pending_ |

### 8e. After the run

1. Promote any **Blocker** or **Serious** finding into Section 6 (Next-pass plan) so it gets triaged on the next sweep.
2. If the run finds zero `Blocker` / `Serious` issues across all three pairs, promote the standing screen-reader compatibility statement (currently "supported but not re-verified in this audit") in the [VPAT 2.4](./vpat-2.4.md) from "Supports" to "Supports (verified April 2026 by manual NVDA + VoiceOver pass)" with a citation back to this section.
3. If the script itself is wrong in places (a step's expected announcement doesn't match real screen-reader behavior even on a clean build), correct the script in `screen-reader-test-script-2026-04.md` so the next pass starts from a faithful baseline.

### 8f. Task #83 attempt log (April 29, 2026) — blocked, no run executed

Task #83 ("Run the prepared screen-reader walkthrough on real NVDA + VoiceOver hardware and fill in the audit results table") was opened on April 29, 2026 to execute the steps in 8c / 8d / 8e. It was closed without filling those tables for the same hardware reason already documented in Section 1 and at the top of Section 8:

- **NVDA** runs only on Microsoft Windows, **VoiceOver** runs only on Apple macOS / iOS, and both produce their primary output as synthesized speech requiring a human listener (or a hardware audio loopback + STT pipeline that this environment does not provide).
- The task-execution environment for Task #83 is the same Linux container used for the original audit and has no Windows / macOS host, no AT software installed, and no audio device. There is no programmatic substitute that would produce results faithful enough to be recorded as a real screen-reader pass — `jest-axe` (Section 7b) and Playwright + `@axe-core/playwright` (Section 7c) cover the structural-DOM regression classes but cannot answer "what did NVDA actually announce on this control," which is the entire point of 8c.
- **No PASS / FAIL / PARTIAL cells in 8c were filled in**, **no severity items were added to 8d**, and **the VPAT 2.4 statement was not promoted per 8e** — fabricating any of those would put untrue claims into a customer-facing accessibility-conformance document. The cells remain `_pending_` so the next attempt starts from an honest baseline.
- **What is still owed:** a human tester with access to (at minimum) a Windows machine running NVDA + Firefox and a macOS machine running VoiceOver + Safari, executing the script at [`./screen-reader-test-script-2026-04.md`](./screen-reader-test-script-2026-04.md) end-to-end and recording results back into 8c / 8d, then following the 8e promotion rules.
- **What does not need to be re-done:** the six ARIA fixes listed in 8a (already shipped), the script in 8b (already written and reviewed), and the CI guards in Section 7 (already wired). Only the human run itself is outstanding.

A new task can be opened against this section when a human tester is available; this attempt log is the only honest record this environment can produce.

## 9. Baseline lint debt cleanup (Task #80, April 26, 2026)

The April 2026 audit added a focused `lint:a11y` CI guard that intentionally side-stepped the pre-existing baseline lint debt so the new guard would only fail on real a11y findings. The debt was tracked as Task #80 and is now closed:

- **75 stale `eslint-disable-next-line` directives removed** (`react-hooks/exhaustive-deps`, `@typescript-eslint/no-explicit-any`, one bare `eslint-disable-next-line` in `tools/ai-feedback.tsx`) across ~50 classroom files. These directives were left behind when the underlying rules were turned off in a prior task; ESLint flagged them all as "no problems were reported" so removal was mechanical (`pnpm exec eslint src --fix`).
- **4 banned `@/components/ui/{card,badge}` imports migrated to `@workspace/ui`** in `src/pages/admin/support.tsx`, `src/pages/support/index.tsx`, and `src/pages/support/[ticket].tsx`.
- **3 wouter v2 `<Link><a></a></Link>` patterns modernized to v3 `<Link href="…" className="…">…</Link>`** in `src/components/PipTipCard.tsx`, `src/pages/admin/compliance.tsx`, and `src/pages/settings/index.tsx` (preserving the `data-testid` on the settings link).
- **`linterOptions.reportUnusedDisableDirectives: "off"` removed** from `eslint.config.js` (the default of "off" is fine — the CLI flag in `lint` now does the work for both scripts).
- **`lint:a11y` collapsed to a thin alias for `lint`** in `package.json`. ~~The `classroom-a11y-lint` workflow definition in `.replit` is unchanged (still `pnpm --filter @workspace/classroom run lint:a11y`); it now transitively runs the full `lint` script. Future cleanup: remove the alias and update the workflow to call `lint` directly.~~ **Closed in Task #85 (April 26, 2026):** the `.replit` workflow has been renamed from `classroom-a11y-lint` → `classroom-lint`, its task args switched from `pnpm --filter @workspace/classroom run lint:a11y` to `pnpm --filter @workspace/classroom run lint`, and the `lint:a11y` alias has been deleted from `artifacts/classroom/package.json`. The Project parent workflow in `.replit` (`workflows.workflow.tasks` for `name = "Project"`) was also updated to reference `classroom-lint`. The new name is no longer misleading: a "classroom-lint failed" CI message could be a real `jsx-a11y` finding **or** a stale `eslint-disable` directive on a non-a11y rule, and the workflow name now reflects that scope.

Verification: `pnpm --filter @workspace/classroom run lint` now exits cleanly (`--report-unused-disable-directives --max-warnings 0`).
