Instructor home shows a setup banner while a course has no class schedule, since that is the one gap that degrades the student experience (free-date opt-outs, no withdrawal locking); it points at the prefilled schedule form and settings and disappears once any class day exists. Calls gain assessment_entered_at, stamped when an outcome is recorded or actually changed (bulk saves that change nothing don't restamp), null for pending calls and legacy imports, and included in the calls export — distinguishing assessed-in-class from assessed-later. The README setup section now gives both install routes: pure pip/venv, and Debian system packages with the apt line. Fixing this uncovered that numpy was missing from the project dependencies (the grading engine needs it; the system-site-packages venv had masked the omission).
