Phase 6: participation grading, gradebook passback, opt-out integrity
Ports the timing-neutral foregone-participation grading scheme from participation_grades.R: answer quality (per-course level points) minus a deduction for participation foregone through unavailability, estimated by Monte Carlo simulation of the actual weighted draw and averaged over when absences fall, plus a small form-filing incentive for drawn-while-absent-without-opt-out days. Reason-blind and luck-protected; zero-answer students floor to 0. Parameters (allowance in SD units, passing line, form penalty, simulation size/seed) are course settings. Verified against the R engine's rendered 2026q2 reports via the new import-legacy command: quality and availability match exactly, finals within Monte Carlo noise; dropped students import as inactive enrollments and are excluded identically. Grades are computed on demand into stored GradeRun snapshots and reviewed on a grades page with CSV export and per-student reports (also served to students via a publish toggle). Display scales map points to UW 4.0, a threshold table (one-click import of the Canvas course grading scheme), or raw points. Gradebook passback via AGS sits behind a settings toggle with a review-then-push flow. Opt-out withdrawals are now soft-deletes with a withdrawn_at audit trail, and close when class begins (class days gained optional start times), so availability records cannot be rewritten after the fact.
