+# Accessibility Implementation Progress
+
+## Session Summary - 2026-02-09
+
+### Completed Tasks (Phase 1)
+
+✅ **Task 1: Setup accessibility testing infrastructure**
+- Added `axe-core-rspec` gem to Gemfile (test group)
+- Created `spec/accessibility/` directory structure
+- Created `spec/support/accessibility_helpers.rb` with custom WCAG test helpers
+- Created comprehensive documentation:
+  - `spec/accessibility/README.md` - Testing guide with WCAG criteria, manual testing procedures
+  - `spec/accessibility/SETUP_NOTES.md` - Setup instructions and gem installation notes
+- Commit: `aa9cb026` - "Add Phase 1 accessibility infrastructure and semantic landmarks"
+
+✅ **Task 2: Add semantic landmarks to layouts**
+- Added `<main id="main-content">` landmark to `app/views/layouts/application.html.erb`
+- Added `<nav aria-label="Main navigation">` to `app/views/shared/_navbar.html.erb`
+- Added skip navigation link with keyboard-focus visibility
+- Skip link uses `translate-y-0` on focus for proper keyboard access
+- Satisfies WCAG 2.4.1 (Bypass Blocks, Level A)
+- Commit: `aa9cb026` - Same commit as Task 1
+
+✅ **Task 3: Fix image alt text in Vue components**
+- Fixed 6 images across 4 Vue files:
+  - `submission_form/signature_step.vue` - Signature preview
+  - `submission_form/initials_step.vue` - Initials preview
+  - `submission_form/image_step.vue` - Uploaded image preview
+  - `submission_form/area.vue` - 3 field types (image, stamp, KBA, signature, initials)
+- All alt text uses dynamic `field.name` with descriptive fallbacks
+- Satisfies WCAG 1.1.1 (Non-text Content, Level A)
+- Commit: `743e7e5c` - "Add alt text to all images in Vue submission form components"
+
+✅ **Task 4: Fix image alt text in Rails views**
+- Fixed 8 images across 4 ERB files:
+  - `submissions/show.html.erb` - 4 images (thumbnails, pages, signatures, attachments)
+  - `profile/index.html.erb` - 2 images (user signature and initials)
+  - `submissions/_value.html.erb` - 2 images (signature with metadata, field images)
+  - `submit_form/show.html.erb` - 1 image (document pages)
+- All alt text uses i18n support with `t()` helper
+- Satisfies WCAG 1.1.1 (Non-text Content, Level A)
+- Commit: `24fa7450` - "Add alt text to all images in Rails ERB views"
+
+### Remaining Phase 1 Tasks
+
+⏳ **Task 5: Add ARIA labels to icon-only buttons**
+- **Priority**: High
+- **Files to fix**:
+  - `app/javascript/template_builder/controls.vue` - Up/down/delete buttons
+  - `app/views/shared/_navbar.html.erb` - Icon buttons in navigation
+  - Modal close buttons throughout the app
+- **Estimated**: 30+ icon-only buttons need `aria-label` attributes
+
+⏳ **Task 6: Add keyboard support to custom elements**
+- **Priority**: High
+- **Files to fix**:
+  - `app/javascript/elements/clipboard_copy.js` - Add Enter/Space handlers
+  - `app/javascript/elements/download_button.js` - Add keyboard activation
+  - `app/javascript/elements/password_input.js` - Add keyboard toggle
+- **Required**: Each element needs `keydown` event listeners for Enter and Space keys
+
+⏳ **Task 7: Write accessibility tests for Phase 1 fixes**
+- **Priority**: Medium
+- **Tests needed**:
+  - `spec/accessibility/layouts_spec.rb` - Test landmarks and skip link
+  - `spec/accessibility/images_spec.rb` - Test all images have alt text
+  - `spec/accessibility/buttons_spec.rb` - Test icon buttons have labels
+  - `spec/accessibility/keyboard_spec.rb` - Test custom element keyboard support
+- **Note**: Requires Ruby 4.0.1 and bundle install for axe-core-rspec gem
+
+### Blockers
+
+🚫 **Ruby Version Issue**
+- Project requires Ruby 4.0.1 (specified in Gemfile)
+- System Ruby is 2.6.10
+- No Ruby version manager installed (rbenv, asdf)
+- **Impact**: Cannot run `bundle install` to install axe-core-rspec gem
+- **Workaround**: Testing infrastructure is in place; tests can be written but not executed yet
+- **Resolution**: Install rbenv/asdf and Ruby 4.0.1, then run `bundle install`
+
+### Phase 1 Progress
+
+**Completed**: 4 of 7 tasks (57%)
+**Status**: On track
+**Next Steps**:
+1. Complete Task 5 (ARIA labels for icon buttons)
+2. Complete Task 6 (Keyboard support for custom elements)
+3. Resolve Ruby version blocker
+4. Complete Task 7 (Write and run accessibility tests)
+
+### WCAG 2.2 Criteria Addressed
+
+✅ **1.1.1 Non-text Content (Level A)** - All images now have alt text
+✅ **2.4.1 Bypass Blocks (Level A)** - Skip navigation link added
+✅ **1.3.1 Info and Relationships (Level A)** - Semantic landmarks (main, nav) added
+
+### Next Session Recommendations
+
+1. **Continue Phase 1**: Complete remaining 3 tasks
+2. **Address icon-only buttons**: Most critical for keyboard/screen reader users
+3. **Test keyboard navigation**: Manually verify custom elements are accessible
+4. **Prepare for Phase 2**: Form error associations and ARIA live regions
