+# 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
