+# Authorization System Implementation Summary
+
+## ✅ Implementation Complete
+
+A comprehensive polymorphic record sharing and authorization system has been implemented with CASL, Objection.js, and NestJS.
+
+## What Was Built
+
+### Backend (NestJS + Objection.js + CASL)
+
+#### 1. Database Layer
+- ✅ Migration for authorization tables (`20250128000001_add_authorization_system.js`)
+- ✅ Updated Prisma schema with new models
+- ✅ Objection.js models: `ObjectField`, `RoleRule`, `RecordShare`
+- ✅ Updated existing models with new relations
+
+#### 2. Authorization Core
+- ✅ `AbilityFactory` - Builds CASL abilities from 3 layers (global, role, share)
+- ✅ Query scoping utilities for SQL-level authorization
+- ✅ Guards and decorators (`AbilitiesGuard`, `@CheckAbility()`, `@CurrentUser()`)
+- ✅ Middleware for attaching abilities to requests
+
+#### 3. API Endpoints
+- ✅ **ShareController** - CRUD for record shares
+  - POST /shares - Create share
+  - GET /shares/record/:objectDefinitionId/:recordId - List shares
+  - GET /shares/granted - Shares granted by user
+  - GET /shares/received - Shares received by user
+  - PATCH /shares/:id - Update share
+  - DELETE /shares/:id - Revoke share
+
+- ✅ **RoleController** - Role management
+  - Standard CRUD for roles
+  - RoleRuleController for CASL rules
+
+- ✅ **ObjectAccessController** - Object-level permissions
+  - GET/PUT /setup/objects/:apiName/access
+  - POST /setup/objects/:apiName/fields/:fieldKey/permissions
+  - PUT /setup/objects/:apiName/field-permissions
+
+### Frontend (Nuxt 3 + Vue 3)
+
+#### 4. Object Management Enhancement
+- ✅ Added "Access & Permissions" tab to object setup page
+- ✅ `ObjectAccessSettings.vue` component:
+  - Configure access model (public/owner/mixed)
+  - Set public CRUD permissions
+  - Configure owner field
+  - Set field-level read/write permissions
+
+#### 5. Role Management
+- ✅ New page: `/setup/roles`
+- ✅ `RolePermissionsEditor.vue` component:
+  - Configure CRUD permissions per object
+  - Apply conditions (e.g., own records only)
+  - Visual permission matrix
+
+#### 6. Record Sharing
+- ✅ `RecordShareDialog.vue` component:
+  - List current shares
+  - Add new shares with permissions
+  - Field-level scoping
+  - Expiration dates
+  - Revoke shares
+
+## Key Features
+
+### 🌍 Global Object Policies
+- Public/private access models
+- Default CRUD permissions per object
+- Configurable owner field
+- Field-level default permissions
+
+### 👥 Role-Based Access
+- CASL rules stored in database
+- Per-object permissions
+- Condition-based rules (e.g., ownerId matching)
+- Multiple actions per rule
+
+### 🔗 Per-Record Sharing
+- Polymorphic design (works with any object type)
+- Grant read/update access to specific users
+- Optional field-level scoping
+- Expiration and revocation support
+- Track who granted each share
+
+### 🔒 SQL Query Scoping
+- Critical for list endpoints
+- Ensures users only see authorized records
+- Combines ownership + sharing logic
+- Works with public access flags
+

+
+## Next Steps
+
+### 1. Run the Migration
+```bash
+cd backend
+npm run migrate:latest
+```
+
+### 2. Initialize Existing Objects
+Set default access models for existing object definitions:
+```sql
+UPDATE object_definitions 
+SET 
+  access_model = 'owner',
+  public_read = false,
+  public_create = false,
+  public_update = false,
+  public_delete = false,
+  owner_field = 'ownerId'
+WHERE access_model IS NULL;
+```
+
+### 3. Apply Query Scoping
+Update existing controllers to use query scoping:
+
+```typescript
+import { applyReadScope } from '@/auth/query-scope.util';
+
+// In your list endpoint
+async findAll(@CurrentUser() user: User) {
+  const objectDef = await ObjectDefinition.query(this.knex)
+    .findOne({ apiName: 'YourObject' });
+  
+  let query = YourModel.query(this.knex);
+  query = applyReadScope(query, user, objectDef, this.knex);
+  
+  return query;
+}
+```
+
+### 4. Add Route Protection
+Use guards on sensitive endpoints:
+
+```typescript
+@UseGuards(JwtAuthGuard, AbilitiesGuard)
+@CheckAbility({ action: 'update', subject: 'Post' })
+async update(@Body() data: any) {
+  // Only users with 'update' permission on 'Post' can access
+}
+```
+
+### 5. Frontend Integration
+Add sharing button to record detail pages:
+
+```vue
+<template>
+  <div>
+    <!-- Your record details -->
+    <Button @click="showShareDialog = true">
+      <Share class="w-4 h-4 mr-2" />
+      Share
+    </Button>
+    
+    <RecordShareDialog
+      :open="showShareDialog"
+      :object-definition-id="objectDefinition.id"
+      :record-id="record.id"
+      :fields="objectDefinition.fields"
+      @close="showShareDialog = false"
+    />
+  </div>
+</template>
+```
+
+## Testing Checklist
+
+- [ ] Run database migration successfully
+- [ ] Create a test role with permissions
+- [ ] Configure object access settings via UI
+- [ ] Share a record with another user
+- [ ] Verify shared record appears in grantee's list
+- [ ] Verify query scoping filters unauthorized records
+- [ ] Test field-level permissions
+- [ ] Test share expiration
+- [ ] Test share revocation
+- [ ] Test role-based access with conditions
+
+## Performance Considerations
+
+1. **Index Usage**: The migration creates proper indexes on foreign keys and commonly queried columns
+2. **Query Scoping**: Uses SQL EXISTS subqueries for efficient filtering
+3. **Ability Caching**: Consider caching abilities per request (already done via middleware)
+4. **Batch Loading**: When checking multiple records, batch the share lookups
+
+## Security Notes
+
+⚠️ **Important**: Always use SQL query scoping for list endpoints. Never fetch all records and filter in application code.
+
+✅ **Best Practices**:
+- Share creation requires ownership verification
+- Only grantors can update/revoke shares
+- Expired/revoked shares are excluded from queries
+- Field-level permissions are enforced on write operations
+
+## Documentation
+
+Full documentation available in:
+- [AUTHORIZATION_SYSTEM.md](./AUTHORIZATION_SYSTEM.md) - Comprehensive guide
+- Inline code comments in all new files
+- JSDoc comments on key functions
+
+## Support
+
+For questions or issues:
+1. Check the documentation in `docs/AUTHORIZATION_SYSTEM.md`
+2. Review example usage in the controllers
+3. Examine the test cases (when added)

+# Polymorphic Record Sharing + Authorization System
+
+This document describes the implementation of a comprehensive authorization system using CASL, Objection.js, and NestJS.
+
+## Overview
+
+The system supports:
+- **Global object policies** - Public/private access, default permissions per object type
+- **Role-based access** - Permissions assigned to roles, with CASL rule storage
+- **Per-record sharing** - Polymorphic sharing where owners can grant specific users access to individual records
+- **Field-level permissions** - Fine-grained control over which fields can be read/written
+
+## Architecture
+
+### Database Schema
+
+#### `object_definitions` (Enhanced)
+- `accessModel`: 'public' | 'owner' | 'mixed'
+- `publicRead/Create/Update/Delete`: Boolean flags for public access
+- `ownerField`: Field name storing record owner (default: 'ownerId')
+
+#### `field_definitions` (Enhanced)
+- `defaultReadable`: Boolean - Can this field be read by default
+- `defaultWritable`: Boolean - Can this field be written by default
+
+These permission flags are added directly to the existing `field_definitions` table, keeping all field metadata in one place.
+
+#### `role_rules` (New)
+- `roleId`: FK to roles
+- `rulesJson`: JSON array of CASL rules
+
+#### `record_shares` (New)
+Polymorphic sharing table:
+- `objectDefinitionId`: FK to object_definitions
+- `recordId`: String (supports UUID/int)
+- `granteeUserId`: User receiving access
+- `grantedByUserId`: User granting access
+- `actions`: JSON array of actions ["read", "update", etc.]
+- `fields`: Optional JSON array of field names
+- `expiresAt/revokedAt`: Optional expiry and revocation timestamps
+
+### Backend Components
+
+#### AbilityFactory (`src/auth/ability.factory.ts`)
+Builds CASL abilities from three layers:
+1. **Global rules** - From object_definitions and object_fields
+2. **Role rules** - From role_rules.rulesJson
+3. **Share rules** - From record_shares for the user
+
+```typescript
+const ability = await abilityFactory.buildForUser(user, knex);
+if (ability.can('read', 'Post')) {
+  // User can read posts
+}
+```
+
+#### Query Scoping (`src/auth/query-scope.util.ts`)
+SQL-level filtering for list queries:
+
+```typescript
+import { applyReadScope } from '@/auth/query-scope.util';
+
+const query = Post.query(knex);
+applyReadScope(query, user, objectDefinition, knex);
+// Query now only returns records user can access
+```
+
+Logic:
+1. If `publicRead` is true → allow all
+2. Else → owner OR valid share exists
+
+#### Guards & Decorators
+- `AbilitiesGuard` - Checks CASL abilities on routes
+- `@CheckAbility()` - Decorator to require specific permissions
+- `@CurrentUser()` - Inject current user
+- `@CurrentAbility()` - Inject CASL ability
+
+#### Controllers
+
+**ShareController** (`src/rbac/share.controller.ts`)
+- `POST /shares` - Create a share
+- `GET /shares/record/:objectDefinitionId/:recordId` - List shares for a record
+- `GET /shares/granted` - List shares granted by current user
+- `GET /shares/received` - List shares received by current user
+- `PATCH /shares/:id` - Update a share
+- `DELETE /shares/:id` - Revoke a share
+
+**RoleController** (`src/rbac/role.controller.ts`)
+- Standard CRUD for roles
+- `RoleRuleController` manages CASL rules per role
+
+**ObjectAccessController** (`src/object/object-access.controller.ts`)
+- `GET /setup/objects/:apiName/access` - Get access config
+- `PUT /setup/objects/:apiName/access` - Update access model
+- `POST /setup/objects/:apiName/fields/:fieldKey/permissions` - Set field permissions
+- `PUT /setup/objects/:apiName/field-permissions` - Bulk update field permissions
+
+### Frontend Components
+
+#### ObjectAccessSettings (`components/ObjectAccessSettings.vue`)
+Integrated into object management page as "Access & Permissions" tab:
+- Configure access model (public/owner/mixed)
+- Set public CRUD permissions
+- Configure owner field
+- Set default read/write permissions per field
+
+#### RecordShareDialog (`components/RecordShareDialog.vue`)
+Dialog for sharing individual records:
+- List current shares
+- Add new share with user email
+- Select read/update permissions
+- Optional field-level scoping
+- Optional expiration date
+- Revoke shares
+
+#### Role Management (`pages/setup/roles.vue`)
+Complete role management interface:
+- List all roles
+- Create new roles
+- Delete roles
+- Edit role permissions
+
+#### RolePermissionsEditor (`components/RolePermissionsEditor.vue`)
+Granular permission editor:
+- Configure CRUD permissions per object type
+- Apply conditions (e.g., "ownerId = $userId")
+- Field-level restrictions (future)
+
+## Usage Examples
+
+### 1. Set Object to Owner-Only Access
+
+```typescript
+await api.put('/setup/objects/Post/access', {
+  accessModel: 'owner',
+  publicRead: false,
+  ownerField: 'ownerId'
+});
+```
+
+### 2. Share a Record
+
+```typescript
+await api.post('/shares', {
+  objectDefinitionId: 'abc-123',
+  recordId: 'post-456',
+  granteeUserId: 'user-789',
+  actions: ['read', 'update'],
+  fields: ['title', 'body'], // Optional field scoping
+  expiresAt: '2025-12-31T23:59:59Z' // Optional expiry
+});
+```
+
+### 3. Create Role with Permissions
+
+```typescript
+// Create role
+const role = await api.post('/roles', {
+  name: 'Account Manager',
+  description: 'Can manage accounts'
+});
+
+// Set permissions
+await api.post('/role-rules', {
+  roleId: role.id,
+  rulesJson: [
+    {
+      action: ['read', 'update'],
+      subject: 'Account',
+      conditions: { ownerId: '$userId' } // Only own accounts
+    },
+    {
+      action: ['read'],
+      subject: 'Contact' // Can read all contacts
+    }
+  ]
+});
+```
+
+### 4. Query with Authorization
+
+```typescript
+// In a controller
+async getRecords(user: User) {
+  const objectDef = await ObjectDefinition.query(this.knex)
+    .findOne({ apiName: 'Post' });
+  
+  const query = Post.query(this.knex);
+  applyReadScope(query, user, objectDef, this.knex);
+  
+  return query; // Only returns records user can read
+}
+```
+
+### 5. Check Instance Permission
+
+```typescript
+// With CASL
+const post = await Post.query().findById(id);
+if (ability.can('update', subject(post, 'Post'))) {
+  // User can update this post
+}
+```
+
+## Migration Guide
+
+1. **Run Migration**
+   ```bash
+   npm run migrate:latest
+   ```
+
+2. **Update Existing Objects**
+   Set default access model for existing object types:
+   ```sql
+   UPDATE object_definitions 
+   SET access_model = 'owner', 
+       owner_field = 'ownerId'
+   WHERE access_model IS NULL;
+   ```
+
+3. **Update Controllers**
+   Add query scoping to list endpoints:
+   ```typescript
+   import { applyReadScope } from '@/auth/query-scope.util';
+   
+   // Before
+   const records = await MyModel.query();
+   
+   // After
+   const records = await applyReadScope(
+     MyModel.query(),
+     user,
+     objectDef,
+     knex
+   );
+   ```
+
+4. **Add Guards**
+   Protect routes with ability checks:
+   ```typescript
+   @UseGuards(JwtAuthGuard, AbilitiesGuard)
+   @CheckAbility({ action: 'read', subject: 'Post' })
+   async findAll() {
+     // ...
+   }
+   ```
+
+## Security Considerations
+
+1. **Always use SQL scoping for lists** - Don't rely on post-fetch filtering
+2. **Validate share ownership** - Only grantor can update/revoke shares
+3. **Check expiry and revocation** - Filter out invalid shares in queries
+4. **Field-level filtering** - Strip unauthorized fields from request bodies
+5. **Tenant isolation** - All queries should be scoped to current tenant (if multi-tenant)
+
+## Testing
+
+### Unit Tests
+Test ability building:
+```typescript
+it('should allow owner to read their records', async () => {
+  const ability = await abilityFactory.buildForUser(user, knex);
+  const post = { id: '123', ownerId: user.id };
+  expect(ability.can('read', subject(post, 'Post'))).toBe(true);
+});
+```
+
+### Integration Tests
+Test query scoping:
+```typescript
+it('should only return owned records', async () => {
+  const query = Post.query(knex);
+  applyReadScope(query, user, objectDef, knex);
+  const records = await query;
+  
+  expect(records.every(r => r.ownerId === user.id)).toBe(true);
+});
+```
+
+## Future Enhancements
+
+- [ ] Group/team sharing (share with multiple users)
+- [ ] Public link sharing (token-based)
+- [ ] Audit log for shares
+- [ ] Share templates
+- [ ] Cascading shares (share related records)
+- [ ] Time-limited shares with auto-expiry
+- [ ] Share approval workflow
+- [ ] Delegation (share on behalf of another user)
+

-# Salesforce-Style Authorization System
-
-## Overview
-Implemented a comprehensive authorization system based on Salesforce's model with:
-- **Org-Wide Defaults (OWD)** for record visibility
-- **Role-based permissions** for object and field access
-- **Record sharing** for granular access control
-- **CASL** for flexible permission evaluation
-
-## Architecture
-
-### 1. Org-Wide Defaults (OWD)
-Controls baseline record visibility for each object:
-- `private`: Only owner can see records
-- `public_read`: Everyone can see, only owner can edit/delete
-- `public_read_write`: Everyone can see and modify all records
-
-### 2. Role-Based Object Permissions
-Table: `role_object_permissions`
-- `canCreate`: Can create new records
-- `canRead`: Can read records (subject to OWD)
-- `canEdit`: Can edit records (subject to OWD)
-- `canDelete`: Can delete records (subject to OWD)
-- `canViewAll`: Override OWD to see ALL records
-- `canModifyAll`: Override OWD to edit ALL records
-
-### 3. Field-Level Security
-Table: `role_field_permissions`
-- `canRead`: Can view field value
-- `canEdit`: Can modify field value
-
-### 4. Record Sharing
-Table: `record_shares`
-Grants specific users access to individual records with:
-```json
-{
-  "canRead": boolean,
-  "canEdit": boolean,
-  "canDelete": boolean
-}
-```
-
-## Permission Evaluation Flow
-
-```
-1. Check role_object_permissions
-   ├─ Does user have canCreate/Read/Edit/Delete?
-   │  └─ NO → Deny
-   │  └─ YES → Continue
-   │
-2. Check canViewAll / canModifyAll
-   ├─ Does user have special "all" permissions?
-   │  └─ YES → Grant access
-   │  └─ NO → Continue
-   │
-3. Check OWD (orgWideDefault)
-   ├─ public_read_write → Grant access
-   ├─ public_read → Grant read, check ownership for write
-   └─ private → Check ownership or sharing
-   
-4. Check Ownership
-   ├─ Is user the record owner?
-   │  └─ YES → Grant access
-   │  └─ NO → Continue
-   │
-5. Check Record Shares
-   └─ Is record explicitly shared with user?
-      └─ Check accessLevel permissions
-```
-
-## Field-Level Security
-
-Fields are filtered after record access is granted:
-1. User queries records → Apply record-level scope
-2. System filters readable fields based on `role_field_permissions`
-3. User updates records → System filters editable fields
-
-## Key Features
-
-### Multiple Role Support
-- Users can have multiple roles
-- Permissions are **unioned** (any role grants = user has it)
-- More flexible than Salesforce's single profile model
-
-### Active Share Detection
-- Shares can expire (`expiresAt`)
-- Shares can be revoked (`revokedAt`)
-- Only active shares are evaluated
-
-### CASL Integration
-- Dynamic ability building per request
-- Condition-based rules
-- Field-level permission support
-
-## Usage Example
-
-```typescript
-// In a controller/service
-constructor(
-  private authService: AuthorizationService,
-  private tenantDbService: TenantDatabaseService,
-) {}
-
-async getRecords(tenantId: string, objectApiName: string, userId: string) {
-  const knex = await this.tenantDbService.getTenantKnex(tenantId);
-  
-  // Get user with roles
-  const user = await User.query(knex)
-    .findById(userId)
-    .withGraphFetched('[roles.[objectPermissions, fieldPermissions]]');
-  
-  // Get object definition
-  const objectDef = await ObjectDefinition.query(knex)
-    .findOne({ apiName: objectApiName });
-  
-  // Build query with authorization scope
-  let query = knex(objectApiName.toLowerCase());
-  query = await this.authService.applyScopeToQuery(
-    query,
-    objectDef,
-    user,
-    'read',
-    knex,
-  );
-  
-  const records = await query;
-  
-  // Get field definitions
-  const fields = await FieldDefinition.query(knex)
-    .where('objectDefinitionId', objectDef.id);
-  
-  // Filter fields user can read
-  const filteredRecords = await Promise.all(
-    records.map(record => 
-      this.authService.filterReadableFields(record, fields, user)
-    )
-  );
-  
-  return filteredRecords;
-}
-
-async updateRecord(tenantId: string, objectApiName: string, recordId: string, data: any, userId: string) {
-  const knex = await this.tenantDbService.getTenantKnex(tenantId);
-  
-  const user = await User.query(knex)
-    .findById(userId)
-    .withGraphFetched('[roles.[objectPermissions, fieldPermissions]]');
-  
-  const objectDef = await ObjectDefinition.query(knex)
-    .findOne({ apiName: objectApiName });
-  
-  // Get existing record
-  const record = await knex(objectApiName.toLowerCase())
-    .where({ id: recordId })
-    .first();
-  
-  if (!record) {
-    throw new NotFoundException('Record not found');
-  }
-  
-  // Check if user can update this record
-  await this.authService.assertCanPerformAction(
-    'update',
-    objectDef,
-    record,
-    user,
-    knex,
-  );
-  
-  // Get field definitions
-  const fields = await FieldDefinition.query(knex)
-    .where('objectDefinitionId', objectDef.id);
-  
-  // Filter to only editable fields
-  const editableData = await this.authService.filterEditableFields(
-    data,
-    fields,
-    user,
-  );
-  
-  // Perform update
-  await knex(objectApiName.toLowerCase())
-    .where({ id: recordId })
-    .update(editableData);
-  
-  return knex(objectApiName.toLowerCase())
-    .where({ id: recordId })
-    .first();
-}
-```
-
-## Migration
-
-Run the migration to add authorization tables:
-```bash
-npm run knex migrate:latest
-```
-
-The migration creates:
-- `orgWideDefault` column in `object_definitions`
-- `role_object_permissions` table
-- `role_field_permissions` table
-- `record_shares` table
-
-## Next Steps
-
-1. **Migrate existing data**: Set default `orgWideDefault` values for existing objects
-2. **Create default roles**: Create Admin, Standard User, etc. with appropriate permissions
-3. **Update API endpoints**: Integrate authorization service into all CRUD operations
-4. **UI for permission management**: Build admin interface to manage role permissions
-5. **Sharing UI**: Build interface for users to share records with others
