Related WCAG success criteria

Indicative mapping for compliance reporting — not a conformance claim. Criteria: 1.3.1, 4.1.2

How this rule is checked

AI lane — enable with --enable-ai. Judgment runs via Cursor/agent using prompts under design-rules/ai/prompts/generated/.

Module: docs/design/a11y-audit/ai-enabled-a11y-principles.md#ai-a11y-ks-region-labeling. See Before / After below.

Purpose

AI judgment overlay (ks scope).

Passing signals

  • DOM and/or repo signals satisfy the rule implementation in tools/website-a11y-auditor.
  • For axe-backed WCAG criteria, use --lanes axe,det with an appropriate --standard preset.

Failing signals

  • Auditor emits a finding with ruleId AI.A11Y.KS.REGION_LABELING on the crawled URL.
  • Harness: auditor-tests/invoke-a11y-ruleset-harness.sh AI.A11Y.KS.REGION_LABELING expects ≥1 finding on the Before fixture.

Evidence and remediation

  1. Reproduce with analyze-website-a11y.mjs --only-deterministic-rule-ids AI.A11Y.KS.REGION_LABELING when lane is deterministic.
  2. Apply the After markup pattern (or fix generator source for KS rules).
  3. Re-run harness or audit until the rule is clean on the target URL.
