// README — Legalitize

What this codebase is and what it does

Legalitize is a complete legal intelligence SaaS platform. The codebase is a monorepo containing a React TypeScript frontend, a Node.js TypeScript API, a PostgreSQL database with Prisma ORM, and multiple specialized service modules. The architecture is production-grade — not a prototype or MVP — designed from the start for multi-tenant operation, horizontal scaling, and regulatory compliance.

// REPOSITORY STRUCTURE

Directory	Purpose	LOC (approx)
/frontend	React 18 + TypeScript UI application	~18,400
/api	Express.js REST API + service layer	~14,200
/engine	Document generation, AI orchestration, jurisdiction rules	~9,800
/database	Prisma schema, migrations, seeds	~2,400
/services	Storage, email, payment, auth services	~1,600
/templates	54 document templates (Bluebook-formatted)	~884

// MODULE BREAKDOWN

Module	Function	Complexity
motionGenerator	AI-powered motion drafting with jurisdiction enforcement	High — 1,840 LOC
jurisdictionEngine	Procedural rules for 50+ court systems	Very High — 3,200+ LOC
deadlineCalculator	Statutory deadline computation	Medium — 920 LOC
packetAssembler	Court filing packet generation	High — 1,440 LOC
civilRightsSuite	§1983 analysis and complaint generation	Very High — 2,800 LOC
recordsAutomation	FOIA/records-access/records access request management	High — 1,600 LOC
evidenceVault	Encrypted document storage + indexing	Medium — 980 LOC
educationLaw	IDEA / Section 504 / CPSL module	High — 1,380 LOC
authService	JWT + session + RBAC	Medium — 760 LOC
pdfEngine	PDF-lib document rendering	High — 1,120 LOC

// KEY ARCHITECTURAL DECISIONS

TypeScript everywhere. Strict TypeScript across frontend and backend eliminates an entire class of runtime errors and makes the codebase self-documenting. Type safety is enforced at API boundaries via Zod schemas.

Jurisdiction rules as data, not code. Court procedural rules are stored as structured JSON configuration objects, not hard-coded logic. Adding a new jurisdiction requires adding configuration, not rewriting functions.

AI as a service, not a dependency. The document generation system treats AI as one component in a pipeline: rules engine → template selection → AI generation → format validation → Bluebook enforcement → output. AI failure does not break the system.

Security at every layer. Input validation (Zod), output sanitization, encrypted storage, JWT auth, RBAC, and row-level security enforcement. Not bolted on — baked in from the start.

// Code Samples

Representative samples from the production codebase

These samples illustrate the engineering quality, TypeScript discipline, and domain-specific architecture across multiple modules.

engine/jurisdictionEngine.ts — Rules LoadingTypeScript

// Jurisdiction rules engine — loads court-specific
// procedural requirements for any supported court
interface JurisdictionConfig {
  court: CourtCode;
  pageLimit: number;
  fontRequirement: FontSpec;
  captionFormat: CaptionTemplate;
  filingRequirements: FilingRule[];
  companionForms: FormCode[];
}

export class JurisdictionEngine {
  private ruleCache: Map<string, JurisdictionConfig> = new Map();

  async load(court: CourtCode): Promise<JurisdictionConfig> {
    const cached = this.ruleCache.get(court);
    if (cached) return cached;

    const rules = await loadRulesFromStore(court);
    this.ruleCache.set(court, rules);
    return rules;
  }
}

engine/civilRights/analyze1983.ts — Violation MappingTypeScript

// §1983 constitutional violation analysis engine
export async function analyzeCivilRightsViolations(
  facts: CaseFacts,
  defendants: Defendant[]
): Promise<ViolationAnalysis> {

  const violations = await identifyViolations(facts);

  const defendantMap = defendants.map(d => {
    const theories = getLegalTheories(d.type, violations);
    const QIExposure = assessQualifiedImmunity(d, violations);
    const monell = d.type === 'MUNICIPALITY'
      ? analyzeMonellPolicy(d, facts)
      : null;

    return { defendant: d, theories, QIExposure, monell };
  });

  return { violations, defendantMap, recommendedClaims: rankClaims(violations) };
}

database/schema.prisma — Core Data ModelPrisma

// Core matter model — multi-tenant, isolated per user
model Matter {
  id           String     @id @default(cuid())
  userId       String
  title        String
  caseType     CaseType

  court        String

  documents    Document[]
  parties      Party[]
  deadlines    Deadline[]

}

services/deadlineCalculator.ts — Procedural DeadlinesTypeScript

// Calculates statutory deadlines from filing events
// Business day aware, court holiday compliant
export function calculateDeadlines(
  filingDate: Date,
  documentType: DocumentType,
  jurisdiction: JurisdictionCode
): DeadlineSet {

  const rules = getDeadlineRules(documentType, jurisdiction);

  return rules.map(rule => {
    const deadline = addBusinessDays(
      filingDate,
      rule.days,
      getCourtHolidays(jurisdiction)
    );
    return {
      type: rule.type,
      date: deadline,
      authority: rule.ruleRef,
      priority: rule.priority
    };
  });
