Accessibility Contract

Purpose

Purpose

Ensure UI work remains grounded in real user access rather than superficial compliance theatre.

Baseline principles

  1. Native semantics first.
  2. Visible labels should generally provide the accessible name.
  3. ARIA is used only when needed and correctly.
  4. Keyboard operation is a first-class requirement.
  5. Focus management must be intentional.
  6. Status changes must be understandable.
  7. Dense dashboards still need clear structure.

Required for every UI-affecting task

The agent must identify:

  • impacted user journeys
  • semantics changed
  • focus order changed
  • keyboard interaction changed
  • accessible name changes
  • status message changes
  • table or chart comprehension changes
  • colour and perception risk

Findings model

Use these categories:

  • deterministic_failure
  • corroborated_failure
  • engine_limited_review
  • state_limited_review
  • visual_composition_review
  • human_judgement_review
  • advisory_note

Wording restrictions

Never claim:

  • fully accessible
  • compliant
  • WCAG passed
  • accessible for screen readers

unless the repository's defined process has actually earned that statement.

Dashboard-specific guidance

Internal dashboards create recurring problems:

  • charts without meaningful summaries
  • colour-coded severity with no redundant cue
  • filters with weak labels
  • data tables with poor column logic
  • modals and drawers with weak focus return
  • alert toasts that are visually obvious but poorly announced
  • long pages with no landmarks or heading structure

Review focus areas

  • filter panels
  • comparison controls
  • segmented views
  • tab systems
  • error states
  • CSV, PDF, and screenshot export controls
  • audit-history tables
  • drill-down drawers
  • report share dialogs

Testing guidance

Automated checks can catch important classes of issues. They do not eliminate the need for judgement-based review.
