Related WCAG success criteria

Indicative mapping for compliance reporting — not a conformance claim. Criteria: 1.3.5

How this rule is checked

Deterministic lane — scope generic. Detected by det-a11y-generic-*.check.js or the axe lane for WCAG-tagged violations.

  • Harness: auditor-tests/invoke-a11y-ruleset-harness.sh on the Before fixture.
  • Audit: analyze-website-a11y.mjs --only-deterministic-rule-ids DET.A11Y.GENERIC.INPUT_PURPOSE

Module: docs/design/a11y-audit/deterministic-a11y-rules.md#det-a11y-generic-input-purpose. See Before / After below.

Purpose

Personal data fields need autocomplete tokens (1.3.5).

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 DET.A11Y.GENERIC.INPUT_PURPOSE on the crawled URL.
  • Harness: auditor-tests/invoke-a11y-ruleset-harness.sh DET.A11Y.GENERIC.INPUT_PURPOSE expects ≥1 finding on the Before fixture.

Evidence and remediation

  1. Reproduce with analyze-website-a11y.mjs --only-deterministic-rule-ids DET.A11Y.GENERIC.INPUT_PURPOSE 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.
