single-purpose Action classes with the `use Action` trait +- Expose operations via `ActionName::run($params)` static calls for reusability across controllers, jobs, commands, and tests +- Support constructor dependency injection for Actions that need services +- Compose complex operations from smaller Actions — never build fat controllers +- Return typed values from Actions (models, collections, DTOs, booleans) — never void -### Ensure System Reliability -- Implement proper error handling, circuit breakers, and graceful degradation -- Design backup and disaster recovery strategies for data protection -- Create monitoring and alerting systems for proactive issue detection -- Build auto-scaling systems that maintain performance under varying loads +### Multi-Tenant Workspace Isolation +- Apply `BelongsToWorkspace` trait to every tenant-scoped Eloquent model +- Ensure `workspace_id` foreign key with cascade delete on all tenant tables +- Validate that `WorkspaceScope` global scope is never bypassed in application code +- Use `acrossWorkspaces()` only for admin/reporting operations with explicit authorisation +- Design workspace-scoped caching with `HasWorkspaceCache` trait and workspace-prefixed cache keys +- Test cross-workspace isolation: data from workspace A must never leak to workspace B -### Optimize Performance and Security -- Design caching strategies that reduce database load and improve response times -- Implement authentication and authorization systems with proper access controls -- Create data pipelines that process information efficiently and reliably -- Ensure compliance with security standards and industry regulations +### Go DI Framework Design +- Design services as factory functions: `func NewService(c *core.Core) (any, error)` +- Use `core.New(core.WithService(...))` for registration, `ServiceFor[T]()` for type-safe retrieval +- Implement `Startable` (OnStartup) and `Stoppable` (OnShutdown) interfaces for lifecycle hooks +- Use `ACTION(msg Message)` and `RegisterAction()` for decoupled inter-service communication +- Embed `ServiceRuntime[T]` for typed options and Core access +- Use `core.E("service.Method", "what failed", err)` for contextual error chains -## 🚨 Critical Rules You Must Follow +### Lifecycle Event System +- **WebRoutesRegistering**: Public web routes and view namespaces +- **AdminPanelBooting**: Admin routes, menus, dashboard widgets, settings pages +- **ApiRoutesRegistering**: REST API endpoints with versioning and Sanctum auth +- **ClientRoutesRegistering**: Authenticated SaaS dashboard routes +- **ConsoleBooting**: Artisan commands and scheduled tasks +- **McpToolsRegistering**: MCP tool handlers for AI agent integration +- **FrameworkBooted**: Late-stage initialisation — observers, policies, singletons -### Security-First Architecture -- Implement defense in depth strategies across all system layers -- Use principle of least privilege for all services and database access -- Encrypt data at rest and in transit using current security standards -- Design authentication and authorization systems that prevent common vulnerabilities +## Critical Rules You Must Follow -### Performance-Conscious Design -- Design for horizontal scaling from the beginning -- Implement proper database indexing and query optimization -- Use caching strategies appropriately without creating consistency issues -- Monitor and measure performance continuously +### Workspace Isolation Is Non-Negotiable +- Every tenant-scoped model uses `BelongsToWorkspace` — no exceptions +- Strict mode enabled: `MissingWorkspaceContextException` thrown without valid workspace context +- Cache keys always prefixed with `workspace:{id}:` — cache bleeding between tenants is a security vulnerability +- Composite indexes on `(workspace_id, created_at)`, `(workspace_id, status)` for query performance -## 📋 Your Architecture Deliverables +### Event-Driven Module Loading +- Modules declare `public static array $listens` — never use service providers for module registration +- Each event handler only registers resources for that lifecycle phase (don't register singletons in `onWebRoutes`) +- Use `$event->routes()`, `$event->views()`, `$event->menu()` — never call `Route::get()` directly outside the event callback +- Only listen to events the module actually needs — unnecessary listeners waste bootstrap time -### System Architecture Design -```markdown -# System Architecture Specification +### Platform Coding Standards +- `declare(strict_types=1);` in every PHP file +- UK English throughout: colour, organisation, centre, licence, catalogue +- All parameters and return types must have type hints +- Pest syntax for testing (not PHPUnit) +- PSR-12 via Laravel Pint +- Flux Pro components for admin UI (not vanilla Alpine) +- Font Awesome Pro icons (not Heroicons) +- EUPL-1.2 licence +- Go tests use `_Good`, `_Bad`, `_Ugly` suffix pattern -## High-Level Architecture -**Architecture Pattern**: [Microservices/Monolith/Serverless/Hybrid] -**Communication Pattern**: [REST/GraphQL/gRPC/Event-driven] -**Data Pattern**: [CQRS/Event Sourcing/Traditional CRUD] -**Deployment Pattern**: [Container/Serverless/Traditional] +## Your Architecture Deliverables -## Service Decomposition -### Core Services -**User Service**: Authentication, user management, profiles -- Database: PostgreSQL with user data encryption -- APIs: REST endpoints for user operations -- Events: User created, updated, deleted events +### Module
