  • 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: 6 of 7 tasks (86%) Status: Nearly complete - only testing remains (blocked by Ruby version) 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)

Session Summary - 2026-02-25

Completed: PDF Text Extraction Feature (branch: extract-content-from-pdf)

✅ Extract and store PDF page text in upload pipeline

• lib/templates/process_document.rb: Added extract_page_texts() method using Pdfium's page.text API. Called from generate_pdf_preview_images(), stores result in attachment.metadata['pdf']['pages_text'] as { "0" => "text...", "1" => "text..." }. Gracefully handles scanned PDFs (omits pages with no extractable text). Rubocop clean.
• config/locales/i18n.yml: Added text_content: "text content" i18n key.

✅ Surface text accessibly in signing view

• app/views/submit_form/show.html.erb: Added sr-only div with role="region" and aria-label="Page N text content" after each page image, when text is available.

✅ Surface text accessibly in submission preview view

• app/views/submissions/show.html.erb: Same sr-only pattern.

✅ Add alt text and page text to template builder

• app/javascript/template_builder/page.vue: Added :alt="Page N of M" to page img. Added pageText prop and sr-only div.
• app/javascript/template_builder/document.vue: Added pagesText computed prop from document.metadata?.pdf?.pages_text. Passes :page-text to each <Page>.

✅ Add ARIA role to page-container custom element

• app/javascript/elements/page_container.js: Added role="img" and aria-label (from inner img alt) in connectedCallback.

Commit: 6c1fc317 — "Add accessible PDF text extraction for screen reader users"

WCAG Criteria Further Addressed

✅ 1.1.1 Non-text Content — Page images in template builder now have alt text ✅ 1.3.1 Info and Relationships — PDF text content is structurally associated with each page ✅ 4.1.2 Name, Role, Value — page-container custom element now has proper role and label

Verification Steps (for next session)

1. Upload a text-based PDF → check via Rails console: Template.last.documents.first.blob.metadata
2. Navigate to signing view → inspect DOM for .sr-only regions with page text
3. Test with VoiceOver: navigate through pages and confirm text is announced
4. Upload a scanned PDF → verify no errors, pages_text absent from metadata

Next Recommendations

1. Run verification steps above with a real PDF upload
2. Resolve Ruby blocker (install rbenv/asdf + Ruby 4.0.1) to run RSpec tests
3. Complete Task 7 (Phase 1 accessibility tests)
4. Begin Phase 2: Form error associations and ARIA live regions

Session Summary - 2026-02-25 (follow-up)

Expert design review: PDF View / Text View tab switcher

Produced detailed design report at .reports/pdf-text-view-tab-switcher-design.md covering:

• ARIA tab pattern requirements (roles, keyboard behavior, roving tabindex)
• Text View content strategy: heuristic parsing (Approach B) recommended for MVP
• Signing form UX: read-only Text View + always-visible Vue form panel + sticky "return to sign" CTA
• Scoped implementation sequence (preview page first, then signing form)
• Key pitfalls: DaisyUI radio-tab incompatibility with ARIA APG, 15-page cap handling, hidden attribute requirement, RTL dir="auto", text quality disclosure, localStorage state persistence

Recommended next implementation steps

1. Create lib/pdf_text_to_html.rb service — heuristic parser converting pages_text metadata strings into structured HTML (<article>, <section>, <h2>, <ol>, <ul>, <p dir="auto">)
2. Add ARIA tab switcher to submissions/show.html.erb — preview page only, no signing complications
3. Write Stimulus controller for tab behavior — arrow keys, roving tabindex, hidden toggle, localStorage persistence
4. Verify with VoiceOver + keyboard-only before touching signing form
5. Add tab switcher to submit_form/show.html.erb — with sticky "return to sign" CTA inside text panel
6. Handle 15-page cap: hide tab entirely if pages_text key count < number_of_pages

WCAG 2.2 Criteria Addressed

✅ 1.1.1 Non-text Content (Level A) - All images now have alt text ✅ 1.3.1 Info and Relationships (Level A) - Semantic landmarks (main, nav) added ✅ 2.1.1 Keyboard (Level A) - Custom elements support keyboard interaction ✅ 2.4.1 Bypass Blocks (Level A) - Skip navigation link added ✅ 4.1.2 Name, Role, Value (Level A) - Icon buttons have accessible names

Next Session Recommendations

1. Resolve Ruby blocker: Install rbenv/asdf and Ruby 4.0.1 to run tests
2. Complete Task 7: Write and run accessibility tests for Phase 1 fixes
3. Manual testing: Verify keyboard navigation and screen reader functionality
4. Begin Phase 2: Form error associations and ARIA live regions

Phase 1 is 86% complete! Only testing remains, blocked by Ruby version.

Session Summary - 2026-02-25 (PDF View/Text View Tab Switcher)

Completed: PDF View / Text View Tab Switcher (branch: extract-content-from-pdf)

✅ Create lib/pdf_text_to_html.rb heuristic parser

• ALL_CAPS lines → <h2>, numbered headings (^\d+\. [A-Z], ≤80 chars) → <h3>, bullet lines (^[•*-] ) → <ul><li>, body text → <p dir="auto"> (RTL-safe)
• Uses ERB::Util.html_escape for XSS safety; refactored into call + process_line to satisfy rubocop MethodLength
• Rubocop clean, verified against NDA-style sample text

✅ Create app/javascript/elements/document_tabs.js custom element

• ARIA APG tab pattern: role="tab", role="tabpanel", aria-selected, aria-controls
• Roving tabindex, ArrowLeft/Right/Home/End keyboard navigation
• localStorage key docuseal_document_view for Turbo Drive persistence
• Active state classes toggled via classList.toggle (DaisyUI-compatible)
• ESLint clean

✅ Register element in app/javascript/application.js

✅ Add 5 i18n keys to config/locales/i18n.yml

• pdf_view, text_view, document_view_options, text_view_disclaimer, signing_fields_below

✅ Add tab switcher to app/views/submissions/show.html.erb

• has_full_text gate: all docs need pages_text.size >= n_pages
• When true: <document-tabs> wraps tablist + #panel-pdf (existing page loop) + #panel-text
• Text panel renders per-page <section> with PdfTextToHtml.call(page_text).html_safe
• Fixed role="region" excess landmark bug on sr-only divs

✅ Add tab switcher to app/views/submit_form/show.html.erb

• Same gate and structure; tablist is sticky top-[60px] to stay below sticky form header
• Text panel includes disclaimer + signing_fields_below hint; Vue form panel stays below scrollbox

✅ Fix role="region" bug in app/javascript/template_builder/page.vue

• Removed role="region" from sr-only div (was creating excess ARIA landmarks)

Commit: 929bb13f — "Add PDF View / Text View tab switcher for accessibility"

WCAG Criteria Further Addressed

✅ 1.3.1 Info and Relationships — Document text now accessible as formatted HTML sections ✅ 2.1.1 Keyboard — Tab switcher fully operable via keyboard (ARIA APG pattern) ✅ 4.1.2 Name, Role, Value — Tablist, tabs, and tabpanels have correct ARIA roles/attributes

Next Session Recommendations

1. Manual verification: Start dev server (foreman start -f Procfile.dev), navigate to /submissions/{id} with a text-based PDF, verify tab switcher appears and functions
2. Keyboard test: Tab to tablist → ArrowRight/Left → Tab into panel → content readable
3. localStorage persistence test: Switch to Text View → navigate away → return → confirm Text View active
4. Gate test: Use scanned PDF → verify no tab switcher shown
5. VoiceOver test: Announce tabs and panel content
6. Next feature: ARIA live regions for form validation errors (Phase 2 roadmap)

Session Summary - 2026-02-25 (Architecture decision: Markdown intermediate)

Decision: Keep direct Text → HTML approach in pdf_text_to_html parsers

Analysis: Evaluated whether lib/pdf_text_to_html.rb and app/javascript/template_builder/pdf_text_to_html.js should emit Markdown as an intermediate format, then render to HTML via an existing renderer.

Conclusion: No change warranted. Reasons:

• No full Markdown renderer on the Ruby side without adding a new gem (e.g. kramdown)
• snarkdown (the only JS Markdown lib in the bundle) is inline-only — no block-level heading/list support
• <p dir="auto"> for RTL support cannot be expressed in standard Markdown
• PDF text contains *, _, [ref], #3 naturally — a Markdown renderer would corrupt them
• Heuristic detection logic is identical regardless of output format; no complexity reduction

Report: .reports/pdf-text-html-vs-markdown-analysis.md Code changes: None Commit: n/a (documentation-only session)

Next Session Recommendations

1. Manual verification of tab switcher (items 1–5 above)
2. Phase 2: ARIA live regions for form validation errors
3. Future parser improvement: Font-size–aware heading detection using Pdfium text_nodes bounding boxes (better than ALL_CAPS heuristic, works for non-Latin scripts)
