Month 2025-10 Monthly Report: Delivered key improvements across two repos to increase reliability, reduce CI cost, and strengthen validation. In oat-sa/tao-community, CI workflow now runs on pull requests only, removing push triggers to master and release branches, which speeds up feedback and reduces wasted CI resources (commit 74065dbd2f79401d619cf3e2ab256d83ec311f82). In oat-sa/extension-tao-testqti, QTI validation was enhanced to accurately detect SCORE/MAXSCORE declarations in informational items, enabling correct validation rules when forced validation is active (commit 8a90c39eeafca60377c767f72ad2864c556d0a8c). Also fixed and stabilized QTI category ordering by preserving original order in section and test part categories, eliminating unintended sorting (commits ec50e8ec31773d2a1bcb555f47c64129fb5a6f2f; 71f421bee18dbbc21422b24edb594e5cff50dfc0). These changes reduce CI overhead, improve scoring accuracy, and increase test stability. Technologies/skills demonstrated include CI/CD workflow automation with YAML, robust validation logic for QTI items, and test suite reliability improvements.
