# Task 4-5: Team Creation, Role-based Access, and Permission Management

## Agent: main
## Status: Completed

## Work Summary
Implemented comprehensive team management with role-based access control, granular permissions, and permission-based UI visibility.

## Files Modified
1. `src/lib/store.ts` - Added TeamMember interface, ROLE_PRESETS, mock team data, Zustand actions
2. `src/app/admin/page.tsx` - Enhanced TeamManagement, PermissionEditor, AddTeamMemberForm, permission-based tab visibility
3. `src/app/api/admin/team/route.ts` - Added role field support to POST and PATCH handlers

## Key Decisions
- Used ROLE_PRESETS in store for centralized role-permission mapping
- Role selection auto-populates permissions but allows manual override
- Dashboard and Settings tabs always visible regardless of permissions
- Super Admin role excluded from Add Member form dropdown (only assignable by system)
- Each role has distinct visual badge (color + icon) for easy identification
