Executive Summary

This document outlines the technical architecture for refactoring the Oversing organizational management platform and integrating the Runcible Governance Layer. The refactor modernizes a Laravel 4.2 application to Laravel 11 with a modern frontend, while adding certification and governance capabilities for high-liability markets.

Key Objectives

Modernize the technology stack while preserving business logic
Integrate Runcible Governance Layer for LLM output certification
Enable high-liability market access through certified outputs
Maintain feature parity with existing system
Improve developer experience and maintainability
Ensure compliance and audit trail requirements

Architecture Decisions

Platform: Progressive Web App (PWA) – browser-based with native-like capabilities
Backend: Laravel 11 (API-first architecture)
Frontend: React 18 + TypeScript
Database: PostgreSQL (migrated from MySQL)
Real-time: Laravel Reverb (WebSocket server)
Deployment: Containerized (Docker/Kubernetes)

Current State Analysis

Existing System Overview

Technology Stack:

Framework: Laravel 4.2 (PHP 5.x)
Database: MySQL
Frontend: jQuery, RequireJS, Ractive.js
Real-time: Ratchet WebSocket server
Cache: Redis
Queue: Laravel Queue (Redis driver)

Codebase Metrics:

2,214 PHP files
1,404 JavaScript files
390 database migrations
221+ Eloquent models
127+ controllers
812+ Blade views

Key Architectural Patterns

Model Layer:

AbstractBaseModel with extensive trait system
Traits: Workflow, Currency, Permissions, Financial, Activity, etc.
Rich domain models (Task, Program, User, Workflow, WorkLog)

Controller Layer:

BaseController with common functionality
DataTable integration for list views
Permission-based access control

Frontend:

Multi-panel workspace system
Drag-and-drop interfaces
Real-time updates via WebSockets
Component-based (Ractive.js)

Data Processing:

DataProcessor classes for format transformation
Multiple output formats (basic, board, notification, etc.)

Strengths

✅ Well-structured domain models
✅ Comprehensive workflow system
✅ Strong permission model
✅ Activity tracking (audit trail foundation)
✅ Multi-tenant support (ApplicationInstance)
✅ Real-time capabilities

Technical Debt

⚠️ Laravel 4.2 (10+ years old, security concerns)
⚠️ jQuery-based frontend (legacy patterns)
⚠️ Mixed concerns (controllers render views)
⚠️ No API layer (tightly coupled frontend/backend)
⚠️ Limited type safety (PHP 5.x, no TypeScript)
⚠️ MySQL (less suitable for complex queries/audit)

Core Principles

API-First: All functionality exposed via REST/GraphQL APIs
Separation of Concerns: Clear boundaries between layers
Type Safety: TypeScript on frontend, strict types on backend
Event-Driven: Event sourcing for audit trails
Microservices-Ready: Runcible as separate service
Progressive Enhancement: PWA works offline
Security by Design: Zero-trust, defense in depth

export function useTasks(filters: TaskFilters) {

return useQuery({

queryKey: [‘tasks’, filters],

queryFn: () => api.tasks.list(filters),

staleTime: 30000, // 30 seconds

});

Real-time Updates

WebSocket Integration:

// hooks/useWebSocket.ts

export function useWebSocket(channel: string) {

const [data, setData] = useState(null);

useEffect(() => {

const ws = new WebSocket(`wss://api.oversing.com/reverb`);

ws.onopen = () => {

ws.send(JSON.stringify({

event: ‘subscribe’,

channel: channel,

}));

};

ws.onmessage = (event) => {

const message = JSON.parse(event.data);

setData(message.data);

};

return () => ws.close();

}, [channel]);

return data;

}

// sw.ts

import { precacheAndRoute } from ‘workbox-precaching’;

import { registerRoute } from ‘workbox-routing’;

import { NetworkFirst, CacheFirst } from ‘workbox-strategies’;

precacheAndRoute(self.__WB_MANIFEST);

// Cache API responses

registerRoute(

({ url }) => url.pathname.startsWith(‘/api/’),

new NetworkFirst({

cacheName: ‘api-cache’,

})

);

// Cache static assets

registerRoute(

({ request }) => request.destination === ‘image’,

new CacheFirst({

cacheName: ‘images-cache’,

})

);

Risk	Impact	Probability	Mitigation
Extended timeline	High	Medium	Phased approach, MVP first, regular reviews
Feature gaps	Medium	Medium	Comprehensive requirements, user testing
User adoption	High	Low	Training, documentation, gradual rollout
Compliance issues	High	Low	Early compliance review, legal consultation

Mitigation Strategies

Phased Rollout: Start with non-critical features
Feature Flags: Enable/disable features without deployment
Rollback Plan: Ability to revert to old system
Monitoring: Comprehensive observability
Testing: Extensive automated and manual testing
Documentation: Clear migration guides and runbooks

Appendix
