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-client-error-log-clean. Scroll down for Before / After examples and Evidence and remediation steps.

Purpose

Scenario step execution captures console errors/page errors after interactions, not just on initial load.

Evidence and remediation

Re-run tools/ui-app-audit/run-scenario-audit.mjs for the failing scenario; fix script errors on the interaction path. Implementation: tools/website-ux-auditor/design-rules/deterministic/generated/det-app-client-error-log-clean.check.js with metrics.scenarioClientErrorReport from scenario capture.
