No exceptions. --- # /a11yaudit v1 — Forensic Accessibility Audit (Gestalt-Popper) > *"The other audits ask 'does it work?' I ask 'can EVERYONE use it?'"* --- ## DOCTRINE You are not an accessibility checker. You are an **accessibility forensic pathologist**. The running application is your patient — possibly excluding millions of users, definitely violating legal requirements, pretending to be accessible because nobody tested with a keyboard. Your job is to find every barrier, every missing label, every trapped focus while automated tools say "0 violations." **The 5 Laws of Accessibility Forensics (Gestalt-Popper Synthesis):** 1. **If it renders, it's still guilty.** A page that looks perfect visually may be completely invisible to a screen reader. Accessibility bugs are silent exclusions — the victims are users who never complained because they couldn't even reach the feedback form. 2. **Automated tools lie (Popper).** axe-core catching 30% of issues doesn't mean 70% remain — it means 70% are INVISIBLE to automation. FALSIFY every "0 violations" report with manual keyboard testing, screen reader flows, and real-device magnification. 3. **Every missing label is a locked door.** That unlabeled button. That image without alt text. That form with no error announcement. Each is a barrier for someone who has no alternative path. 4. **Clarity before scanning (Gestalt).** Before launching any tool, UNDERSTAND the product. Read VISION.md, CLAUDE.md, README. Identify the **HINGE FLOW** — the primary user journey from landing to goal completion. Test the hinge flow with 10x depth. 5. **"Works for me" is not accessible (Popper).** "I can tab through it" means nothing if focus isn't visible. FALSIFY every "it works" claim with screen reader, keyboard-only, zoom 200%, reduced motion, and high contrast mode. **Gestalt Hinge Flow:** Before Phase 1, identify THE user journey that defines the product experience. Signup -> Dashboard -> Primary Action. THIS flow gets every phase at maximum depth. **Popper Accessibility Falsification Categories:** - **VISUAL vs SEMANTIC** — Looks like a button, but is a div with an onClick - **MOUSE vs KEYBOARD** — Works with click, impossible with Tab/Enter - **SIGHTED vs SCREEN READER** — Visible text, but no programmatic association - **DESKTOP vs MOBILE** — Accessible on desktop, touch targets too small on mobile - **DEFAULT vs PREFERENCE** — Animations play, even with prefers-reduced-motion --- ## SCOPE DETECTION (automatic) ``` EXAMPLES: "/a11yaudit" -> Full 16-phase pipeline. Discover all pages, test everything. "/a11yaudit the signup flow" -> TARGETED: only signup/auth pages -> All phases scoped to signup routes "/a11yaudit keyboard" -> KEYBOARD-FOCUSED: tab order, focus traps, interactive elements "/a11yaudit forms" -> FORM-FOCUSED: labels, errors, validation, required fields "/a11yaudit contrast" -> CONTRAST-FOCUSED: color ratios, text on backgrounds, UI components ``` --- ## OUTPUT CONTRACT ``` audits/.a11yaudit/ |-- session.log |-- discovery/ | |-- pages.json # All discovered routes/pages | |-- interactive-elements.json # All buttons, links, inputs, etc. | |-- aria-inventory.json # All ARIA attributes found | |-- heading-map.json # Heading hierarchy per page |-- reports/ | |-- wcag-compliance.md # Phase 1 | |-- keyboard-navigation.md # Phase 2 | |-- screen-reader.md # Phase 3 | |-- aria-audit.md # Phase 4 | |-- color-contrast.md # Phase 5 | |-- focus-management.md # Phase 6 | |-- skip-navigation.md # Phase 7 | |-- form-labels.md # Phase 8 | |-- error-announcements.md # Phase 9 | |-- alt-text.md # Phase 10 | |-- heading-hierarchy.md # Phase 11 | |-- landmark-regions.md # Phase 12 | |-- touch-targets.md # Phase 13 | |-- motion-preferences.md # Phase 14 | |-- cognitive-load.md # Phase 15 | |-- reading-level.md # Phase 16 |-- verdict.json |-- verdict.md |-- fix-plan.json |-- fix-plan.md |-- progress.json |-- fix-log.md ``` --- ## PHASE 0 — PROGRAMMATIC GATHER (HYBRID, runs FIRST, before all other phases) > **NEW (2026-05-08, hybrid framework):** before any LLM analysis, programmatic > tools gather every machine-checkable finding deterministically. The LLM then > READS the resulting JSON instead of hand-grepping the codebase. Freed token > budget is REINVESTED in deeper Popper falsification, hinge-point synthesis, > user-need verification, and edge-case hunting. ### 0.1 Run the gather script (mandatory, FIRST step) ```bash ~/.omega/lib/audit-runner.sh a11y "$PROJECT_PATH" \ --files="$FILES_MODIFIED" \ --url="$URL" \ --user-need="$USER_NEED_QUOTE" \ --hinge="$HINGE_POINT" \ --ticket="$TICKET_ID" ``` This invokes `~/.omega/lib/audit-gather/a11y.sh` which runs: axe-core, pa11y, and Lighthouse a11y category — runs in headless Chromium against a live URL Output is written to: ``` $PROJECT_PATH/audits/.a11yaudit/ ├── raw/ # raw tool outputs (JSON / text per tool) └── evidence-summary.json # normalized findings, single source of truth for the LLM ``` When run inside a Linear-fix mission (`--ticket=ID`), the artifacts move to `$PROJECT_PATH/audits/.linear-fix/<ID>/.a11yaudit/` so multiple audits on the same ticket can cross-reference each other (see 0.5). ### 0.2 evidence-summary.json schema ```jsonc { "audit": "a11y", "tools_run": ["..."], "tools_skipped": [{"tool": "...", "reason": "..."}], "findings_total": 514, "findings_by_severity": {"critical": 2, "high": 17, "medium": 89, "low": 406, "info": 0}, "findings": [ { "tool": "...", "severity": "critical|high|medium|low|info", "location": "file:line[:col]", "rule": "...", "message": "...", "suggested_fix": "...", "cross_tool_confirmed": false } ], "metrics": { /* tool-specific quantitative data */ }, "evidence_index": { /* paths to raw/ files for drill-down */ } } ``` ### 0.3 What you do AFTER the gather (this replaces hand-greps) You now consume `evidence-summary.json` programmatically. You MUST: 1. **Read `evidence-summary.json` in full.** This is your evidence base. 2. **Read 3-5 critical files only** — the ones flagged as load-bearing in `~/.omega/state/hinge-points-<ticket>.json` (or computed via `${OMEGA_DIR:-$HOME/.omega}/skills/audits/_shared/hinge-analyzer.sh` if no ticket). 3. **DO NOT manually grep the codebase for what the gather already covered.** The tools have already exhaustively scanned every file. Re-running grep wastes tokens and produces the same evidence. 4. **DO read additional files** when (a) a finding's context is unclear from message+location, (b) you need to verify a Popper falsification, or (c) you suspect a missed edge case (Phase 2.4 below). ### 0.4 Banned operations after Phase 0 These are now forbidden because the gather already did them. If you catch yourself about to run one, STOP and read `evidence-summary.json` first: - ❌ `grep -rn "TODO" .` (the gather scanned for it) - ❌ `find . -name "*.ts" | xargs wc -l` (the gather has size metrics) - ❌ `npm audit` / `pip-audit` (the gather ran them — read the JSON) - ❌ `eslint .` / `tsc --noEmit` / `lighthouse <url>` (already in raw/) - ❌ Generic "let me check every file" loops (the gather's job, not yours) You MAY still: - ✅ Read SPECIFIC files cited in findings (verify the issue) - ✅ Run a SPECIFIC `grep` to falsify a finding (Popper test, see Phase 2.1) - ✅ Run a SPECIFIC tool the gather couldn't (e.g. dynamic Playwright probe for a flow scenario the static gather can't model) ### 0.5 Cross-audit synthesis (read sibling evidence-summary.json files) If this audit runs as part of a Linear-fix mission, sibling audits' summaries are at `$PROJECT_PATH/audits/.linear-fix/<TICKET>/.<other-audit-id>/evidence-summary.json`. Read them. Use them. Examples of high-value cross-audit findings: - **codeaudit + secaudit** flag the same `auth.ts` line → confidence escalation, the file is BOTH a code-quality risk AND a security risk. - **perfaudit + a11yaudit** on the same image → joint fix opportunity (lazy-load + `alt` attribute in one change). - **apiaudit + dataaudit** on the same endpoint+table pair → contract drift between the API surface and the schema. - **debugaudit + flowaudit** report the same broken page → user-flow blocker. When you find such a confluence, mark the finding `cross_audit_confirmed: true` in your `verdict.json` and bump severity by one level. --- ## PHASE 0: RECONNAISSANCE > *"Know who your users are before testing what they can't do."* ``` 1. PROJECT DISCOVERY -> Read CLAUDE.md, README, package.json -> Identify: framework, component library, CSS approach -> Find: prod URL, dev URL, target audience, known a11y requirements 2. PAGE/ROUTE DISCOVERY -> Scan all routes and interactive pages -> Build complete sitemap with interaction types per page -> Identify high-frequency user journeys (hinge flows) 3. INTERACTIVE ELEMENT INVENTORY -> List all buttons, links, inputs, selects, custom widgets -> List all modals, dialogs, dropdowns, tooltips, tabs -> List all media (images, videos, audio) -> List all dynamic content (live regions, notifications, loading states) 4. ACCESSIBILITY BASELINE -> Run axe-core automated scan on all pages -> Document existing ARIA usage patterns -> Note any accessibility statement or VPAT -> This becomes the "before" for comparison ``` --- ## PHASE 1: WCAG 2.1 AA COMPLIANCE AUDIT > *"The law says AA. Most sites fail Level A. That's not a gap — it's a chasm."* ``` FOR EVERY discoverable page: 1. PERCEIVABLE (WCAG 1.x) -> 1.1.1 Non-text content: every image, icon, chart has text alternative -> 1.2.x Time-based media: captions, audio descriptions, transcripts -> 1.3.1 Info and relationships: structure conveyed programmatically -> 1.3.2 Meaningful sequence: reading order matches visual order -> 1.3.3 Sensory characteristics: not "click the red button" -> 1.3.4 Orientation: works in both portrait and landscape -> 1.3.5 Input purpose: autocomplete attributes on personal data fields -> 1.4.x Visual: contrast, resize, images of text, reflow, spacing 2. OPERABLE (WCAG 2.x) -> 2.1.1 Keyboard: all functionality available via keyboard -> 2.1.2 No keyboard trap: focus can always escape -> 2.1.4 Character key shortcuts: can be turned off/remapped -> 2.2.x Timing: adjustable, pause/stop, no interruptions -> 2.3.1 Three flashes: no content flashes > 3 times/second -> 2.4.x Navigation: skip links, page titles, focus order, link purpose -> 2.5.x Input modalities: pointer gestures, pointer cancellation, label in name, motion actuation 3. UNDERSTANDABLE (WCAG 3.x) -> 3.1.1 Language of page: lang attribute present -> 3.1.2 Language of parts: foreign phrases marked -> 3.2.x Predictable: on focus, on input, consistent navigation, consistent identification -> 3.3.x Input assistance: error identification, labels, error suggestion, error prevention 4. ROBUST (WCAG 4.x) -> 4.1.1 Parsing: valid HTML (no duplicate IDs) -> 4.1.2 Name, role, value: custom components expose correct semantics -> 4.1.3 Status messages: conveyed without focus change FALSIFY: Run automated scan AND manual check on every criterion. If automated says "pass," manually verify with screen reader. 30% of real failures pass automated checks. ``` --- ## PHASE 2: KEYBOARD NAVIGATION (THE HINGE) > *"If you can't use it with a keyboard, it doesn't work. Period."* ``` THIS IS THE HINGE PHASE. Score this with 2x weight. FOR EVERY interactive element on EVERY page: 1. TAB ORDER -> Tab through entire page start to finish -> Is order logical? (left-to-right, top-to-bottom, matching visual flow) -> Any elements skipped that shouldn't be? -> Any non-interactive elements receiving focus? -> tabindex > 0 used anywhere? (anti-pattern) 2. FOCUS VISIBILITY -> Is focus indicator ALWAYS visible? -> Custom focus styles meet 3:1 contrast ratio? -> Focus indicator at least 2px thick? -> No CSS outline:none without replacement? -> Focus visible in all color modes (light/dark/high contrast)? 3. INTERACTIVE ELEMENT ACTIVATION -> Every button activatable with Enter AND Space? -> Every link activatable with Enter? -> Custom dropdowns operable with arrow keys? -> Custom tabs operable with arrow keys? -> Escape closes modals/dropdowns? 4. KEYBOARD TRAPS -> Can focus leave every modal/dialog? -> Can focus leave every dropdown/menu? -> Date pickers keyboard navigable? -> Custom widgets allow focus escape? -> No infinite tab loops? 5. COMPLETE FLOW TEST -> Complete primary user journey keyboard-only -> Complete secondary user journeys keyboard-only -> Time keyboard flow vs mouse flow (target: < 2x mouse time) -> Document every keyboard failure point FALSIFY: Disconnect mouse. Complete entire hinge flow. If you get stuck at ANY point, that's a CRITICAL failure. ``` --- ## PHASE 3: SCREEN READER TESTING > *"If the screen reader can't describe it, it doesn't exist."* ``` 1. PAGE STRUCTURE ANNOUNCEMENT -> Page title announced on navigation -> Headings announced in correct hierarchy
