Month: 2025-02 — Focused on stabilizing user experience by rolling back looping video experiments across Guardian properties, aligning product behavior with production-ready code and ensuring consistent video playback across surfaces. Actions centered on revert and cleanup to reduce risk and maintenance overhead. Key revert actions and commits: - guardian/dotcom-rendering: Reverted the test loop video container change (commit d189fb7967cc8405ac1309650a6b8b21e6e2c0cb) with message: Revert "Display test loop video container when in 0% AB test". - guardian/frontend: Reverted the looping video AB test (commit 14a50dcf6b9165c28ddb73c9bf106aa06c11ee04) with message: Revert "Add switch and AB test for looping video test". What was delivered (as a rollback-focused action): - Removed isInLoopVideoTest property from components and deleted LoopVideoABTest component and related data in guardian/dotcom-rendering. - Removed experiment definition and its inclusion in the active experiments set to stop the A/B test in guardian/frontend. Overall impact and accomplishments: - Restored stable, consistent user experience for looping video content by removing experimental toggles and dependencies on the looping video test. - Reduced code complexity and maintenance burden by eliminating obsolete AB test code and data paths across two repositories. - Enabled safer production releases and simpler future experimentation with a clear, paused state for looping videos. Technologies/skills demonstrated: - Version control discipline: targeted commits to revert experiments and clean up feature flags. - AB testing lifecycle management: proper rollback of experiments and removal from active sets. - Cross-repo coordination: coordinated rollback across guardian/dotcom-rendering and guardian/frontend. - Code cleanup: removal of isInLoopVideoTest usage, LoopVideoABTest component, and related data structures. - Front-end stability practices: regressions avoided by reverting experimental UI and data paths.
