Indicative mapping for compliance reporting — not a conformance claim. Criteria: 2.4.2
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.shon the Before fixture. - Audit:
analyze-website-a11y.mjs --only-deterministic-rule-ids DET.A11Y.GENERIC.TITLE
Module: docs/design/a11y-audit/deterministic-a11y-rules.md#det-a11y-generic-title. See Before / After below.
Purpose
Deterministic accessibility check (generic 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,detwith an appropriate--standardpreset.
Failing signals
- Auditor emits a finding with
ruleIdDET.A11Y.GENERIC.TITLEon the crawled URL. - Harness:
auditor-tests/invoke-a11y-ruleset-harness.sh DET.A11Y.GENERIC.TITLEexpects ≥1 finding on the Before fixture.
Before example
Before (failing example)
Title
DOM or content signals fail DET.A11Y.GENERIC.TITLE (title).

After example
After (passing example)
Title (remediated)
DOM and content satisfy DET.A11Y.GENERIC.TITLE after remediation.
Deterministic accessibility check (generic scope).
Evidence and remediation
- Reproduce with
analyze-website-a11y.mjs --only-deterministic-rule-ids DET.A11Y.GENERIC.TITLEwhen lane is deterministic. - Apply the After markup pattern (or fix generator source for KS rules).
- Re-run harness or audit until the rule is clean on the target URL.
