Worked on the web-platform-tests/wpt repository to enhance service worker behavior and improve Content Security Policy (CSP) handling in JavaScript environments. Developed a feature ensuring same-origin srcdoc iframes inherit their service worker controller from the parent frame, updating client setup and origin checks while adding automated tests for validation. Addressed a CSP-related bug by modifying Worker creation to dispatch an error event and remain in a non-loaded state instead of throwing a SecurityError, introducing a feature flag and telemetry for monitoring. Focused on JavaScript, service workers, and web workers, the work improved reliability and compatibility in complex web platform scenarios.

Mar 1, 2025March 2025 — Web Platform Tests (web-platform-tests/wpt): Delivered a bug fix for CSP-blocked Worker creation by replacing a thrown SecurityError with a dispatched error event and a non-loaded Worker state. Added a feature flag to toggle this behavior and telemetry to monitor adoption and impact. This work improves site compatibility in CSP-restricted contexts and reduces unexpected script termination, supporting reliability and developer confidence in CSP-heavy deployments.
