Jan 1, 2025January 2025: Delivered targeted reliability and accuracy improvements in the sakai repository (sakaiproject/sakai). Implemented autosave modal stability in Samigo SEB to prevent a permanently displayed modal, improved the correctness of the time-elapsed handling by introducing backup variables for time elapsed and time limit, and ensured correct modal display when the primary time limit is zero. Corrected statistics start date calculation to prevent inaccurate successive statistics by using savedBegin as a fallback only when firstBeginningPresenceBegin is unavailable. Enhanced rubric-based submission validation to require all instructor rubric criteria to be marked before enabling submission and to ensure students complete all self-report criteria in the workflow. These changes improve user experience, data reliability, grading integrity, and workflow compliance for instructors and students. Commits across these changes include: 6130bd2e7fca7b8886f82cbf98f0c9148477d93c, e91307ad9e741e3dc31b13bb9477b8961a5a95a3, f94e68bba7064c1b37066529a5a66f794ff9a9ea, c5fd3381083c9acaa6a4cde0edcf2cdc651e25a98.
