Backend:
- Add ActualController with Cartesian product query (all projects × members)
- Add ActualsService for variance calculations (∞% when actual>0, allocated=0)
- Add ActualResource for API response formatting
- Add migration for notes column on actuals table
- Add global config for inactive project logging (ALLOW_ACTUALS_ON_INACTIVE_PROJECTS)
- Implement filters: project_ids[], team_member_ids[], include_inactive, search
- Add pagination support (25 per page default)
- Register /api/actuals routes
Frontend:
- Create MultiSelect component with portal rendering (z-index fix for sidebar)
- Compact trigger mode to prevent badge overflow
- SSR-safe with browser guards
- Keyboard navigation and accessibility
- Create Pagination component with smart ellipsis
- Rebuild actuals page with:
- Full Cartesian matrix (shows all projects × members, not just allocations)
- Filter section with project/member multi-select
- Active filters display area with badge wrapping
- URL persistence for all filter state
- Month navigation with arrows
- Variance display (GREEN ≤5%, YELLOW 5-20%, RED >20%, ∞% for zero allocation)
- Read-only cells for inactive projects
- Modal for incremental hours logging with notes
- Add actualsService with unwrap:false to preserve pagination meta
- Add comprehensive TypeScript types for grid items and pagination
OpenSpec:
- Update actuals-tracking spec with clarified requirements
- Mark Capability 6: Actuals Tracking as complete in tasks.md
- Update test count: 157 backend tests passing
Fixes:
- SSR error: Add browser guards to portal rendering
- Z-index: Use portal to escape stacking context (sidebar z-30)
- Filter overlap: Separate badge display from dropdown triggers
- Member filter: Derive visible members from API response data
- Pagination meta: Disable auto-unwrap to preserve response structure
