Architecture cleanup: Remove orphans from audit report (37 files)
Deleted orphan component files (4): - dashboard-customizer.tsx (never imported) - unified-communication.tsx (never imported) - data-table.tsx (never imported) - widget-container.tsx (only imported by orphan dashboard-customizer) Deleted unused shadcn/ui primitives (15): - accordion, aspect-ratio, calendar, carousel, chart, form, hover-card, input-otp, menubar, navigation-menu, pagination, radio-group, resizable, toaster, toggle-group (All verified as zero importers) Deleted orphan API route groups (6 directories, 13 route files): - ai-grading-audit (no caller) - demo-data (no caller) - exam-plans (no caller) - grade-analytics (no caller, dead renderView case also removed) - grading-annotations (no caller) - grading-reviews (no caller) Removed dead grade-analytics renderView case + ViewName type entry Removed 10 orphan database models from schema: - NotificationHub, NotificationArchive (superseded by Notification) - WidgetTemplate (dashboard customizer feature abandoned) - EmergencySignage, SignageMessage, SignageSchedule, SignageAuditLog (signage feature - no API routes implemented) - SchoolPolicy, EscalationPolicy, ClassMessagingLock (policy/messaging lock feature - never wired) Also removed 16 relation fields pointing to deleted models. Schema validated, db pushed, lint passes, all 10 tested modules work.
