# Accessibility Intelligence & Inclusive Experience Twin

Webdev Agent OS v21 adds a persistent, evidence-oriented operating model for inclusive web experiences.

## Purpose

Automated scanners are useful but incomplete. The Accessibility Intelligence Twin combines automated evidence with manual assistive-technology journeys, component contracts, content and media governance, cognitive-load review, and human-approved exceptions.

## Evidence chain

1. Inclusive persona and need
2. Critical user journey
3. Semantic and keyboard evidence
4. Screen-reader and voice-control evidence
5. Visual, zoom, reflow, contrast, and motion evidence
6. Caption, transcript, and media evidence
7. Cognitive-load and plain-language evidence
8. Reusable component contract
9. Exception or remediation campaign
10. Release decision

## Operating principle

A passing automated scan is not proof of a usable experience. A conformance claim must remain bounded by the routes, technologies, content, dates, and evidence actually reviewed.

## Primary collections

- Programs and inclusive personas
- Assistive-technology journeys
- Semantic audits and focus maps
- Screen-reader checks
- Voice-control checks
- Visual and motion checks
- Media assets
- Cognitive assessments
- Accessible component contracts
- Exceptions
- Improvement campaigns

## Release blockers

A release should remain blocked when a critical user journey is impossible, keyboard focus is trapped or lost, an essential control has no usable accessible name, critical content lacks an equivalent, or an approved exception has expired without mitigation.
