Related WCAG success criteria
Indicative mapping for compliance reporting — not a conformance claim. Criteria: 3.2.5
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.shon the Before fixture. - Audit:
analyze-website-a11y.mjs --only-deterministic-rule-ids DET.A11Y.GENERIC.CHANGE_ON_REQUEST
Module: docs/design/a11y-audit/deterministic-a11y-rules.md#det-a11y-generic-change-on-request. 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.CHANGE_ON_REQUESTon the crawled URL. - Harness:
auditor-tests/invoke-a11y-ruleset-harness.sh DET.A11Y.GENERIC.CHANGE_ON_REQUESTexpects ≥1 finding on the Before fixture.
Before example
Before (failing example)
Change On Request
DOM or content signals fail DET.A11Y.GENERIC.CHANGE_ON_REQUEST (change on request).
Rule: DET.A11Y.GENERIC.CHANGE_ON_REQUEST · scope: generic
After example
After (passing example)
Change On Request (remediated)
DOM and content satisfy DET.A11Y.GENERIC.CHANGE_ON_REQUEST after remediation.
Deterministic accessibility check (generic scope).
Evidence and remediation
- Reproduce with
analyze-website-a11y.mjs --only-deterministic-rule-ids DET.A11Y.GENERIC.CHANGE_ON_REQUESTwhen 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.
