+## Session: WCAG 2.1 AA Full Audit (2026-02-25)
+
+### What Was Done
+- Ran 4 parallel audit agents covering: ERB views, Vue components, custom JS elements, color contrast
+- Consolidated findings into `.reports/wcag-2.1-aa-audit.md`
+- Total: ~80 issues — 20 critical, 30 major, 30 minor
+
+### Key Critical Findings
+1. `maximum-scale=1.0, user-scalable=no` in application.html.erb — violates 1.4.4
+2. Focus indicators removed on 7+ input elements — violates 2.4.7
+3. turbo_modal.js has no focus management — violates 2.4.3, 2.1.2
+4. alert() / prompt() used in 5 elements — violates 3.3.1, 4.1.3
+5. Signature form controls lack labels — violates 1.3.1
+6. Validation errors never announced — violates 3.3.1
+7. text-gray-100 on dark backgrounds in _embedding.html.erb — ~0.4:1 contrast
+
+### Positive: Tab Switcher Correctly Implemented
+The PDF/Text tab switcher (both ERB and Vue versions) is WCAG-compliant per the audit.
+
+### Recommended Next Steps (Priority Order)
+1. Fix viewport meta tag — 1 line change, critical impact
+2. Fix form.html.erb: add lang attribute + skip link — 2 line changes
+3. Replace alert()/prompt() with live regions — 5 files
+4. Add modal focus management to turbo_modal.js
+5. Add labels to signature form controls
+6. Fix text-gray-100 on dark backgrounds in _embedding.html.erb
+7. Fix outline-none focus:ring-0 on inputs — restore focus visibility

+# WCAG 2.1 AA Accessibility Audit Report — DocuSeal
+
+**Date:** 2026-02-25
+**Standard:** WCAG 2.1 Level AA
+**Scope:** ERB views, Vue components, custom JS elements, color contrast
+**Status:** FAIL — multiple violations identified
+
+---
+
+## Executive Summary
+
+Four specialized audit agents reviewed the full codebase across four domains. A total of **~80 issues** were identified: 20 critical, ~30 major, ~30 minor. The most impactful failures cluster around six themes:
+
+1. Viewport zoom disabled (users with low vision cannot zoom)
+2. Focus indicators removed on many inputs (keyboard users cannot see focus position)
+3. Modal focus not managed (keyboard users get trapped or lose focus)
+4. `alert()` / `prompt()` used for errors (screen readers cannot process these)
+5. Form controls lack proper labels (screen readers cannot describe fields)
+6. Validation errors not announced via live regions
+
+The recent PDF/Text tab switcher implementation is noted as **correctly implemented** (proper ARIA tablist/tab/tabpanel, roving tabindex, keyboard navigation). The sr-only page text pattern is also correctly implemented.
+
+---
+
+## Priority 1 — Critical (Fix Immediately)
+
+### C1. Viewport Zoom Disabled
+**WCAG:** 1.4.4 Resize Text (AA)
+**File:** `app/views/layouts/application.html.erb:8`
+**Issue:** `maximum-scale=1.0, user-scalable=no` prevents users from zooming to 200%.
+**Fix:** Change to `<meta name="viewport" content="width=device-width, initial-scale=1.0">`
+
+---
+
+### C2. Focus Indicators Removed Without Alternative
+**WCAG:** 2.4.7 Focus Visible (AA)
+**Files:**
+- `app/views/templates/_file_form.html.erb:11` — `outline-none focus:ring-0`
+- `app/views/templates_preferences/_recipients.html.erb:15` — same
+- `app/views/templates_clone/_form.html.erb:17` — same
+- `app/javascript/submission_form/phone_step.vue:105` — `!outline-none`
+- `app/javascript/template_builder/font_modal.vue:172` — `outline-none`
+- `app/javascript/template_builder/area.vue:67` — `outline-none` on contenteditable
+- `app/javascript/template_builder/document.vue:9-30` — `focus:outline-none` on tab buttons (no alternative)
+**Fix:** Replace `outline-none focus:ring-0` with `focus:ring-2 focus:ring-base-content focus:ring-offset-1` on each.
+
+---
+
+### C3. Modal Focus Management Absent
+**WCAG:** 2.4.3 Focus Order (A), 2.1.2 No Keyboard Trap (A)
+**File:** `app/javascript/elements/turbo_modal.js` (entire file)
+**Issues:**
+- No focus trap within modal (Tab escapes the modal)
+- No focus moved into modal on open
+- No focus restoration to trigger element on close
+- No `role="dialog"` or `aria-modal="true"`
+**Fix:** On open, store trigger reference, move focus to first focusable element, trap Tab/Shift+Tab; on close, restore focus to trigger. Add `role="dialog" aria-modal="true" aria-labelledby="<title-id>"`.
+
+---
+
+### C4. alert() / prompt() Used for All Errors
+**WCAG:** 3.3.1 Error Identification (A), 4.1.3 Status Messages (AA)
+**Files:**
+- `app/javascript/elements/fetch_form.js:24`
+- `app/javascript/elements/download_button.js:48`
+- `app/javascript/elements/clipboard_copy.js:20`
+- `app/javascript/elements/prompt_password.js:7`
+- `app/javascript/submission_form/signature_step.vue:765-773`
+**Fix:** Replace every `alert()` / `prompt()` with ARIA live region announcements (`role="alert"` or `aria-live="assertive"`). For `prompt_password.js`, replace browser prompt with a custom `role="dialog"` modal containing a labelled input.
+
+---
+
+### C5. Form Controls Lack Associated Labels
+**WCAG:** 1.3.1 Info and Relationships (A), 4.1.2 Name Role Value (A)
+**Files:**
+- `app/javascript/submission_form/signature_step.vue:209-216` — signature text input has no `<label>`
+- `app/javascript/submission_form/signature_step.vue:218-262` — signing reason `<select>` has no `<label>`
+- `app/javascript/submission_form/area.vue:133-141` — checkbox has no label
+- `app/javascript/submission_form/area.vue:153-161` — radio buttons have no labels
+**Fix:** Add `<label for="...">` or `aria-label` to each unlabelled control. For radio/checkbox groups, wrap in `<fieldset>/<legend>` or `role="group" aria-labelledby`.
+
+---
+
+### C6. Validation Errors Not Announced to Screen Readers
+**WCAG:** 3.3.1 Error Identification (A), 4.1.3 Status Messages (AA)
+**Files:**
+- `app/javascript/submission_form/form.vue:35-44` — disabled submit button tooltip not announced
+- `app/javascript/submission_form/signature_step.vue:765-773` — signature too small uses `alert()`
+**Fix:** Add `role="alert" aria-live="polite"` region that updates when form state changes. Remove `alert()` calls. For the "fill all required fields" message, render it in a live region when the button is disabled.
+
+---
+
+### C7. text-gray-100 on Dark Background — Invisible Text
+**WCAG:** 1.4.3 Contrast Minimum (AA) — contrast ~0.4:1
+**File:** `app/views/templates/_embedding.html.erb:58, 63, 91, 103, 138, 156, 196, 214`
+**Fix:** Replace `text-gray-100` with `text-white` on dark code block backgrounds.
+
+---
+
+## Priority 2 — High (Fix This Sprint)
+
+### H1. Missing H1 Heading on Signing Form
+**WCAG:** 2.4.6 Headings and Labels (AA)
+**File:** `app/views/submit_form/show.html.erb:19-20`
+**Issue:** Submission name displayed in a plain `<div>`, not an `<h1>`.
+**Fix:** Change or wrap the submission name div with `<h1 class="...">`.
+
+---
+
+### H2. Form Layout Missing lang Attribute
+**WCAG:** 3.1.1 Language of Page (A)
+**File:** `app/views/layouts/form.html.erb:2`
+**Issue:** `<html data-theme="docuseal">` — no `lang` attribute.
+**Fix:** `<html data-theme="docuseal" lang="<%= I18n.locale %>">`
+
+---
+
+### H3. Form Layout Missing Skip Link
+**WCAG:** 2.4.1 Bypass Blocks (A)
+**File:** `app/views/layouts/form.html.erb`
+**Issue:** Public signing form has no skip navigation link (application layout has one).
+**Fix:** Add skip link before the nav:
+```erb
+<a href="#main-content" class="absolute left-0 top-0 -translate-y-full focus:translate-y-0 z-50 p-4 bg-base-100 text-base-content border-2 border-neutral">
+  <%= t('skip_to_main_content') %>
+</a>
+```
+
+---
+
+### H4. text-gray-300/400 on White/Light Backgrounds — Fails 4.5:1
+**WCAG:** 1.4.3 Contrast Minimum (AA)
+**Files:**
+- `app/javascript/submission_form/signature_step.vue:221,230` — `text-gray-300` select placeholder (~2.2:1)
+- `app/javascript/submission_form/area.vue:211` — `text-gray-400` (~2.1:1)
+- `app/javascript/submission_form/form.vue:207,215` — `text-gray-300` (~2.2:1)
+- `app/javascript/template_builder/conditions_modal.vue:64,106,133` — `text-gray-300` (~2.2:1)
+- `app/javascript/template_builder/import_list.vue:53,80` — `!text-gray-300` (~2.2:1)
+- `app/views/submissions/_send_sms_button.html.erb:3` — `text-gray-400` (~2.1:1)
+**Fix:** Replace with `text-gray-600` (minimum) or `text-base-content/70` on these elements.
+
+---
+
+### H5. Modal Close Buttons Use `<a>` Instead of `<button>`
+**WCAG:** 4.1.2 Name Role Value (A)
+**Files:**
+- `app/views/shared/_turbo_modal.html.erb:10`
+- `app/views/shared/_turbo_modal_large.html.erb:10`
+**Fix:** `<button type="button" data-action="click:turbo-modal#close" aria-label="<%= t('close') %>">&times;</button>`
+
+---
+
+### H6. Duplicate IDs — decline_button
+**WCAG:** 4.1.1 Parsing (A)
+**File:** `app/views/submit_form/show.html.erb:24,42`
+**Fix:** Use `id="decline_button_header"` and `id="decline_button_scroll"`.
+
+---
+
+### H7. Dropdown Keyboard Navigation (Navbar)
+**WCAG:** 2.1.1 Keyboard (A)
+**File:** `app/views/shared/_navbar.html.erb:26-80`
+**Issue:** DaisyUI dropdown with `<label tabindex="0">` has no Enter/Space/Escape/Arrow key handling; `aria-expanded` never updates.
+**Fix:** Add JavaScript keyboard event handling following ARIA APG menu button pattern.
+
+---
+
+### H8. Canvas Elements Lack Text Alternatives
+**WCAG:** 1.1.1 Non-text Content (A)
+**File:** `app/javascript/submission_form/signature_step.vue:171-176`
+**Fix:** Add fallback text inside `<canvas>`: "Signature drawing pad. Use the tools above to draw or type your signature."
+
+---
+
+## Priority 3 — Medium (Address in Next Sprint)
+
+### M1. Color-Only Submitter Indicators (Colored Dots)
+**WCAG:** 1.3.3 Sensory Characteristics (A)
+**File:** `app/views/submissions/show.html.erb:193,202`
+**Fix:** Add `aria-hidden="true"` to the colored dot; add adjacent text labels like "Party 1", "Party 2".
+
+---
+
+### M2. Color-Only Field Type Indicators (Template Builder)
+**WCAG:** 1.4.1 Use of Color (A)
+**File:** `app/javascript/template_builder/area.vue:646-672`
+**Fix:** Add text label or icon in addition to the color-coded border/background.
+

+
+### M3. Contenteditable Field Name Lacks ARIA
+**WCAG:** 4.1.2 Name Role Value (A)
+**File:** `app/javascript/template_builder/area.vue:65-73`
+**Fix:** Add `role="textbox" aria-multiline="false" aria-label="Field name"` to the contenteditable `<span>`.
+
+---
+
+### M4. toggle_visible / field_condition Don't Set aria-expanded / aria-hidden
+**WCAG:** 4.1.2 Name Role Value (A)
+**Files:** `app/javascript/elements/toggle_visible.js`, `app/javascript/elements/field_condition.js`
+**Fix:** Set `aria-expanded` on trigger; set `aria-hidden="true"` on hidden targets.
+
+---
+
+### M5. Password Visibility Toggle Lacks aria-label / aria-pressed
+**WCAG:** 4.1.2 Name Role Value (A)
+**File:** `app/javascript/elements/password_input.js:11-18`
+**Fix:** Add `aria-label="Show password"` / `"Hide password"` toggled on state change. Add `aria-pressed`.
+
+---
+
+### M6. Dynamic List (add/remove items) No Focus Management
+**WCAG:** 2.4.3 Focus Order (A)
+**File:** `app/javascript/elements/dynamic_list.js:11-26`

+**WCAG:** 3.3.1 Error Identification (A)
+**File:** `app/views/profile/index.html.erb:65-82`
+**Fix:** Display per-field error messages with `aria-describedby` linking field to error span; wrap in `role="alert"`.
+
+---
+
+### M9. Placeholder Colors at Very Low Opacity (area.vue contenteditable)
+**WCAG:** 1.4.3 Contrast Minimum (AA)
+**Files:**
+- `app/javascript/template_builder/area.vue:303` — `before:text-base-content/30` (~2.1:1)
+- `app/javascript/template_builder/contenteditable.vue:14` — `before:text-neutral-400` (~2.8:1)
+**Fix:** Raise opacity to `/60` minimum on visible placeholder pseudo-elements.
+
+---
+
+### M10. Icon-Only Buttons Missing aria-label Consistently
+**WCAG:** 4.1.2 Name Role Value (A)
+**Files:** Various `submission_form/` and `template_builder/` Vue components
