February 2026: Delivered robust QTI scale handling enhancements in the TAO test framework, improving outcome declarations processing, scale selection, and filename formatting; expanded unit test coverage and refined code structure for maintainability and faster issue detection.

For 2026-01, oat-sa/extension-tao-testqti focused on stabilizing item session handling and preserving expected outcome behavior. Delivered two critical bug fixes with targeted commits, enhancing test reliability and preventing runtime errors. The work reduced flaky tests and safeguarded downstream test scoring logic.

December 2025 performance snapshot: Key features delivered: - Scale-Based Scoring and Scale Management implemented for oat-sa/extension-tao-testqti. Introduced a ScaleHandler service to persist scales, updated the test model to include test scales, and added UI support to select scales during the test creation workflow. This delivers configurable, scale-driven scoring and reduces manual interpretation errors. Major bugs fixed: - Fixed scoring logic by updating outcome properties from interpretation to scale, ensuring scoring uses the new Scale framework. - Removed scalePresets from addGradeOutcome to prevent incorrect scale presets and improve data integrity. Overall impact and accomplishments: - Enhanced scoring accuracy and configurability across outcomes, enabling consistent reporting and analytics. - Streamlined test authoring with scale-aware UI, reducing time to configure tests and improving user experience. - Layed groundwork for scalable analytics via a persistent ScaleHandler and scale-aware data model, contributing to maintainability and future feature velocity. Technologies/skills demonstrated: - Service-oriented design (ScaleHandler) and persistence layer for scales. - Data model evolution (test scales) and UI integration within test creation flow. - PR-driven improvements and code hygiene (aligned with PRs #2688 and #2676). Commit highlights: - f3b4f34b4697b879977ec73270650c73951a3435: feat: Re-apply Handle Scale in OutcomeDeclaration (#2688) with related fixes.

Month: 2025-09 — Delivered ACL Roles Management Interface in oat-sa/tao-core, introducing a new ACL domain interface with backend support for managing roles, including actions and controllers for file uploads, exports, and health checks to support secure LTI launches. This work improves code structure and maintainability, enabling secure, scalable access control for LTI deployments.

April 2025 performance summary for oat-sa/tao-core: Delivered critical enhancements to ResourceRelationServiceProxy, including container handling improvements, and tightened deletion logic to prevent data inconsistencies. Updated TAO version metadata to reflect new capabilities. These changes improve data integrity, reliability of operations in containerized environments, and set the foundation for safer maintenance and future refactors.
