- Evidence on assignments: photo upload + notes + student self-note (needs help / not sure) - Evidence required/optional/none flag per item; grading queue shows evidence with lightbox thumbnail - Parent comment field when grading; shown to student on graded items - Offline tasks: 3-state status (not started → in progress → done) with inline evidence form - Retake policy per item: latest / highest / average — gradebook computes effective score accordingly - Grading queue expanded to include lessons and practices (not just assignments) when evidence present Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
