1. Introduction

1.1 Purpose

This document outlines the complete architecture for Libra Law Firm's web platform. It serves as the single source of truth for development, ensuring consistency and guiding AI-driven implementation.

1.2 Project Overview

Libra Law Firm is a bilingual (Arabic/English) Laravel application serving as both a public-facing website and internal management tool for:

• Client consultation booking and management
• Case timeline tracking
• Legal content publishing
• Administrative operations

1.3 Key Constraints

Constraint	Details
Single Admin	One lawyer manages all operations
No Online Payments	All payments handled offline
Client-Managed Infrastructure	Rocky Linux 9 server
No Self-Registration	Admin creates all client accounts
Bilingual Requirement	Arabic (RTL) primary, English (LTR) secondary

1.4 Project Context

Existing Foundation:

• Laravel 12.43.1 with Fortify authentication
• Livewire 3.7.3 + Volt 1.10.1 for reactive components
• Flux UI Free 2.10.2 component library
• Tailwind CSS 4.1.11
• Pest 4.2.0 testing framework

---

2. High Level Architecture

2.1 Technical Summary

Libra is a server-rendered Laravel monolith with Livewire for reactive UI. The architecture follows Laravel's MVC pattern enhanced with:

• Livewire 3 + Volt for interactive components without JavaScript complexity
• Fortify for headless authentication with custom Volt views
• Eloquent ORM for database operations
• Blade + Flux UI for consistent, accessible component design
• Queue workers for background email processing and scheduled reminders

This architecture prioritizes simplicity and maintainability over distributed complexity.

2.4 Architectural Patterns

Pattern	Description	Rationale
MVC + Livewire	Laravel MVC with Livewire reactive components	Standard Laravel pattern; eliminates need for separate SPA
Action Classes	Single-purpose classes for business logic	Keeps controllers thin; reusable; testable
Form Objects	Livewire form objects for validation	Encapsulates validation; reusable forms
Observer Pattern	Eloquent observers for model events	Automatic audit logging, notification triggers
Queue-based Processing	Background jobs for emails and heavy operations	Non-blocking UX; reliable delivery
Policy-based Authorization	Laravel Policies for access control	Clean separation of authorization logic
Repository Pattern	Optional for complex queries	Only if query complexity warrants

7. Authentication & Authorization

7.1 Authentication (Fortify)

Current Configuration:

• Email/password login
• Email verification
• Two-factor authentication (TOTP)
• Password reset

Modifications Required:

1. Disable public registration - Admin creates all users
2. Custom login redirect - Admin → /admin/dashboard, Client → /client/dashboard
3. Admin-triggered password reset - No public reset

// config/fortify.php
'features' => [
    // Features::registration(), // DISABLED
    Features::resetPasswords(),
    Features::emailVerification(),
    Features::updateProfileInformation(),
    Features::updatePasswords(),
    Features::twoFactorAuthentication([
        'confirm' => true,
        'confirmPassword' => true,
    ]),
],

7.2 Authorization (Policies)

// app/Policies/ConsultationPolicy.php
class ConsultationPolicy
{
    public function viewAny(User $user): bool
    {
        return true; // All authenticated users can see their own
    }

    public function view(User $user, Consultation $consultation): bool
    {
        return $user->isAdmin() || $consultation->user_id === $user->id;
    }

    public function create(User $user): bool
    {
        return $user->isClient();
    }

    public function update(User $user, Consultation $consultation): bool
    {
        return $user->isAdmin();
    }

    public function delete(User $user, Consultation $consultation): bool
    {
        return $user->isAdmin();
    }
}

// app/Policies/TimelinePolicy.php
class TimelinePolicy
{
    public function viewAny(User $user): bool
    {
        return true;
    }

    public function view(User $user, Timeline $timeline): bool

        return $user->isAdmin();
    }

    public function update(User $user, Timeline $timeline): bool
    {
        return $user->isAdmin();
    }

    public function addUpdate(User $user, Timeline $timeline): bool
    {
        return $user->isAdmin();
    }
}

// app/Policies/UserPolicy.php

15. Performance & Optimization

15.1 Performance Targets

Metric	Target	Measurement
Page Load (TTFB)	< 200ms	Server response time
Full Page Load	< 3s	Including assets
Database Queries	< 20 per page	Query monitoring
Memory Usage	< 128MB	Per request
Queue Job Processing	< 5s	For email jobs

15.2 Database Optimization

// Eager loading in components
public function mount(): void
{
    $this->consultations = Consultation::query()
        ->with('user:id,full_name,email,phone')
        ->where('status', ConsultationStatus::Pending)
        ->orderBy('created_at', 'desc')
        ->get();
}

// Chunking for large operations
User::query()
    ->where('status', UserStatus::Active)
    ->chunk(100, function ($users) {
        foreach ($users as $user) {
            // Process
        }
    });

15.3 Caching Strategy

Cache	TTL	Key Pattern	Invalidation
Working Hours	1 hour	working_hours:all	On update
Blocked Times	1 hour	blocked_times:{month}	On update
Dashboard Stats	5 minutes	admin:stats:{date}	Time-based
Published Posts	10 minutes	posts:published	On publish
User Permissions	1 hour	user:{id}:permissions	On role change

// app/Services/AvailabilityService.php
public function getWorkingHours(): Collection
{
    return Cache::remember('working_hours:all', now()->addHour(), function () {
        return WorkingHour::where('is_active', true)->get();
    });
}

public function invalidateWorkingHoursCache(): void
{
    Cache::forget('working_hours:all');
}

15.4 Asset Optimization

// vite.config.js
import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';

export default defineConfig({
    plugins: [
        laravel({
            input: ['resources/css/app.css', 'resources/js/app.js'],
            refresh: true,
        }),
    ],
    build: {
        rollupOptions: {
            output: {
                manualChunks: {
                    vendor: ['alpinejs'],
                },
            },
        },

18. Error Handling & Graceful Degradation

18.1 Exception Handling

// bootstrap/app.php
->withExceptions(function (Exceptions $exceptions) {
    // Don't report certain exceptions
    $exceptions->dontReport([
        \Illuminate\Auth\AuthenticationException::class,
        \Illuminate\Validation\ValidationException::class,
    ]);

    // Custom rendering for specific exceptions
    $exceptions->render(function (NotFoundHttpException $e, Request $request) {
        if ($request->is('admin/*')) {
            return response()->view('errors.admin-404', [], 404);
        }
        if ($request->is('client/*')) {
            return response()->view('errors.client-404', [], 404);
        }
        return response()->view('errors.404', [], 404);
    });

    $exceptions->render(function (AuthorizationException $e, Request $request) {
        return response()->view('errors.403', [
            'message' => $e->getMessage(),
        ], 403);
    });

    // Report to external service
    $exceptions->reportable(function (\Throwable $e) {
        if (app()->bound('sentry')) {
            app('sentry')->captureException($e);
        }
    });
})

18.2 Graceful Degradation Strategy

Failure	Impact	Degradation Strategy
Email Service Down	Notifications not sent	Queue emails, retry with backoff, log failures, continue operation
Cache Unavailable	Slower responses	Fallback to database queries, log warning
Queue Worker Down	Delayed processing	Jobs remain in database, process when restored
Database Slow	Slow page loads	Show cached data where possible, timeout long queries

18.3 Email Failure Handling

// app/Jobs/SendBookingNotification.php
class SendBookingNotification implements ShouldQueue
{
    use Queueable;

    public int $tries = 3;
    public array $backoff = [60, 300, 900]; // 1min, 5min, 15min

    public function handle(): void
    {
        Mail::to(config('libra.admin_email'))
            ->send(new NewBookingRequestMail($this->consultation));
    }

    public function failed(\Throwable $exception): void
    {
        // Log the failure
        Log::error('Failed to send booking notification', [
            'consultation_id' => $this->consultation->id,
            'attempts' => $this->attempts(),
            'error' => $exception->getMessage(),
        ]);

        // Create in-app notification as fallback
        Notification::create([
            'user_id' => User::where('user_type', UserType::Admin)->first()?->id,
            'type' => 'booking_notification_failed',
            'data' => [
                'consultation_id' => $this->consultation->id,
                'message' => 'Email notification failed - please check manually',
            ],
        ]);
    }
}

18.4 Livewire Error Handling

// In Volt components
public function submit(): void
{
    try {
        $this->validate();

        $result = app(CreateConsultationAction::class)->execute(
            $this->user,
            $this->form->toArray()
        );

        $this->dispatch('notify', [
            'type' => 'success',
            'message' => __('messages.booking_submitted'),
        ]);

        $this->redirect(route('client.consultations.index'));

    } catch (ValidationException $e) {
        throw $e; // Let Livewire handle validation

    } catch (BookingLimitExceededException $e) {
        $this->addError('form.booking_date', $e->getMessage());

    } catch (\Exception $e) {
        report($e); // Log the error

        $this->dispatch('notify', [
            'type' => 'error',
            'message' => __('messages.general_error'),
        ]);
    }
}

Rule	Description
Volt Pattern	Use class-based Volt components (per CLAUDE.md)
Flux UI	Use Flux components when available
Form Validation	Always use Form Request or Livewire form objects
Eloquent	Prefer Model::query() over DB:: facade
Actions	Use single-purpose Action classes for business logic
Testing	Every feature must have corresponding Pest tests
Pint	Run vendor/bin/pint --dirty before committing

20.2 Naming Conventions

Element	Convention	Example
Models	Singular PascalCase	Consultation
Tables	Plural snake_case	consultations
Columns	snake_case	booking_date
Controllers	PascalCase + Controller	ConsultationController
Actions	Verb + Noun + Action	CreateConsultationAction
Jobs	Verb + Noun	SendBookingNotification
Events	Past tense	ConsultationApproved
Listeners	Verb phrase	SendApprovalNotification
Volt Components	kebab-case path	admin/consultations/index
Enums	PascalCase	ConsultationStatus
Enum Cases	PascalCase	NoShow
Traits	Adjective or -able	HasConsultations, Bookable
Interfaces	Adjective or -able	Exportable

21. Technology Alternatives Considered

21.1 Frontend Framework

Option	Pros	Cons	Decision
Livewire 3 + Volt	No JS build, Laravel native, simple state management	Learning curve, larger payload	SELECTED
React/Vue SPA	Rich ecosystem, familiar to many	Separate build, API needed, complexity	Rejected
Blade + Alpine only	Simplest, no Livewire overhead	Limited interactivity	Considered for simpler features
Inertia.js	Best of both worlds	Additional complexity, less documentation	Rejected

Rationale: Livewire 3 provides excellent developer experience with Laravel, eliminates API development overhead, and Volt single-file components align well with the project's maintainability goals.

21.2 Database

Option	Pros	Cons	Decision
MariaDB	MySQL compatible, open source, client preference	-	SELECTED (Production)
SQLite	Zero config, fast tests, portable	Not suitable for production	SELECTED (Development)
PostgreSQL	Advanced features, JSON support	Overkill for this project	Rejected
MySQL	Industry standard	MariaDB preferred by client	Rejected

21.3 Authentication

Option	Pros	Cons	Decision
Laravel Fortify	Headless, flexible, 2FA support	Requires custom views	SELECTED
Laravel Breeze	Quick setup, includes views	Less flexible, opinionated	Rejected
Laravel Jetstream	Full-featured, team support	Too complex, Livewire/Inertia choice	Rejected
Custom auth	Full control	Reinventing wheel, security risks	Rejected

21.4 Queue System

Option	Pros	Cons	Decision
Database	Simple, no extra services	Slower than Redis	SELECTED
Redis	Fast, feature-rich	Additional service to maintain	Future consideration
Amazon SQS	Managed, scalable	Overkill, cost, lock-in	Rejected
Beanstalkd	Lightweight, fast	Less Laravel integration	Rejected

Rationale: Database queue driver is sufficient for expected volume (~100 jobs/day). Redis can be added later if performance requires.

21.5 CSS Framework

Option	Pros	Cons	Decision
Tailwind CSS 4	Utility-first, RTL support, Flux UI compatible	Learning curve	SELECTED
Bootstrap 5	Familiar, RTL plugin	Larger bundle, less flexible	PRD mentioned but Tailwind preferred
Custom CSS	Full control	Time-consuming, maintenance burden	Rejected
