+Use `ModelRules` (from `pkg/modelregistry`) to control per-entity auth behavior:
+
+```go
+modelregistry.RegisterModelWithRules("public.products", &Product{}, modelregistry.ModelRules{
+    SecurityDisabled: false,   // true = skip all auth checks
+    CanPublicRead:    true,    // unauthenticated GET allowed

+    CanUpdate:        true,    // authenticated users can update
+    CanDelete:        false,   // authenticated users cannot delete
+})
+```
+
+`CheckModelAuthAllowed(secCtx, operation)` applies these rules in `BeforeHandle`:
+1. `SecurityDisabled` → allow all
+2. `CanPublicRead/Create/Update/Delete` → allow unauthenticated for that operation
+3. Guest (UserID == 0) → return 401
+4. Authenticated → allow (operation-specific `CanUpdate`/`CanDelete` checked in `BeforeUpdate`/`BeforeDelete`)

 ## Authentication
 
-Implement authentication using hooks:
+Use `RegisterSecurityHooks` for integrated auth with model-rule support:
+
+```go
+import "github.com/bitechdev/ResolveSpec/pkg/security"
+
+provider := security.NewCompositeSecurityProvider(auth, colSec, rowSec)
+securityList := security.NewSecurityList(provider)
+websocketspec.RegisterSecurityHooks(handler, securityList)
+// Registers BeforeHandle (model auth), BeforeRead (load rules),
+// AfterRead (column security + audit), BeforeUpdate, BeforeDelete
+```
+
+Or implement custom authentication using hooks directly:
 
 ```go
 handler := websocketspec.NewHandlerWithGORM(db)
