How this rule is fixed

Pilot deterministic fixer: plan_only · harness mode live_scenario · verify live_scenario.

See fixer module for plan_only in lib/ux-deterministic-fixers/.

Detection module: docs/design/ux-audit/deterministic-design-rules.md#det-app-toast-lifecycle. Scroll down for Before / After examples and Evidence and remediation steps.

Purpose

Toast/status messages use role=status or aria-live, can dismiss when persistent, and do not cover primary controls.

Evidence and remediation

Run tools/website-ux-auditor/auditor-tests/invoke-det-ruleset-harness.sh --only-rule DET.APP.TOAST_LIFECYCLE. Implementation: tools/website-ux-auditor/design-rules/deterministic/generated/det-app-toast-lifecycle.check.js.
