February 2026 (2026-02) monthly summary for oat-sa/extension-tao-itemqti. Focused on UX enhancements for item navigation, robust item identity, and loader/bundle quality with accessibility improvements. Delivered: 1) Vertical writing mode and scrolling UI enhancements, including shared partials and orientation-aware labels to improve interaction with scrollable items; 2) Configurable item identifier generation with reliability improvements, including validation, observer callback stability, and tests; 3) QTI loader and bundle enhancements with accessibility, compatibility, and performance improvements, plus expanded test coverage; and 4) extended test activities, including QUnit coverage for itemLoader strategies and extendedText interactions. Significant bug fixes included correct orientation and dimension labeling based on writing mode, preventing missed observer callbacks, and resolving conflicts with develop. This work reduces UX friction, increases reliability of item lifecycles, and improves maintainability and performance across the TAO item qti extension.

September 2025 highlights include delivering a feature-flag driven enhancement for permanent late submissions in the TestQTI extension, stabilizing late-saving behavior on timeouts, and upgrading the TestQTI dependency to v48.21.3. The work improved submission reliability during timeout events, reduced risk of unintended data loss, and strengthened cross-repo alignment between extension-tao-testqti and tao-community. Notable fixes included correcting the validation method and removing an unnecessary type cast, with tests updated to exercise the feature flag. Documentation updates accompanied code changes, and test/tooling adjustments were completed to support ongoing validation and deployment.

In July 2025, focused on reliability and data integrity for the oat-sa/extension-tao-testqti extension by delivering Late Submission Handling in the Timeout Service. The feature conditionally saves item responses only when late submissions are allowed and adds robust handling for invalid or empty responses during timeouts, ensuring the tools state is saved and the runner service check executes. This work reduces the risk of data corruption during timeouts and improves end-to-end scoring reliability. Key commits and outcomes include the fix commit addressing timeout handling: 20169e7f9ef2f671755c3f19c4bf98ef88c312fd.
