Command Pattern Each regulatory operation is encapsulated as a discrete command with consistent interfaces: ```typescript interface RegulatoryCommand { execute(options: CommandOptions): Promise; validate(options: CommandOptions): ValidationResult; authorize(context: AuthContext): boolean; } ``` **Benefits:** - Standardized command execution - Audit trail generation - Permission checking - Rollback capabilities ### 2. State Machine Pattern Regulations follow a defined state machine for lifecycle management: ```typescript enum RegulationState { DRAFT = 'draft', REVIEW = 'review', CONSULTATION = 'consultation', PUBLISHED = 'published', EFFECTIVE = 'effective', SUSPENDED = 'suspended', REVOKED = 'revoked' } class RegulationStateMachine { private allowedTransitions: Map = new Map([ [RegulationState.DRAFT, [RegulationState.REVIEW, RegulationState.CONSULTATION]], [RegulationState.REVIEW, [RegulationState.DRAFT, RegulationState.CONSULTATION]], [RegulationState.CONSULTATION, [RegulationState.PUBLISHED, RegulationState.DRAFT]], [RegulationState.PUBLISHED, [RegulationState.EFFECTIVE, RegulationState.SUSPENDED]], [RegulationState.EFFECTIVE, [RegulationState.SUSPENDED, RegulationState.REVOKED]], [RegulationState.SUSPENDED, [RegulationState.EFFECTIVE, RegulationState.REVOKED]] ]); } ``` ### 3. Chain of Responsibility Pattern Enforcement actions follow a escalation chain: ```typescript abstract class EnforcementHandler { protected nextHandler?: EnforcementHandler; setNext(handler: EnforcementHandler): EnforcementHandler { this.nextHandler = handler; return handler; } abstract handle(violation: Violation): EnforcementAction | null; } class WarningHandler extends EnforcementHandler { handle(violation: Violation): EnforcementAction | null { if (violation.severity === 'low' && violation.isFirstOffense) { return new WarningAction(violation); } return this.nextHandler?.handle(violation) || null; } } ``` ### 4. Observer Pattern Event-driven notifications for regulatory actions: ```typescript interface RegulatoryObserver { onRegulationPublished(regulation: Regulation): void; onViolationDetected(violation: Violation): void; onEnforcementAction(action: EnforcementAction): void; } class PublicNotificationObserver implements RegulatoryObserver { onRegulationPublished(regulation: Regulation): void { this.notificationService.send({ type: 'regulation_published', regulation: regulation.id, effectiveDate: regulation.effectiveDate }); } } ``` ## Core Components ### 1. CLI Interface Layer **Technology:** Commander.js with TypeScript **Responsibility:** Command parsing, validation, help generation, global option handling ```typescript // cli.ts const program = new Command(); program .name('pact-gov') .description('PACT Gov CLI - Government regulatory operations') .version(packageJson.version) .hook('preAction', async (thisCommand) => { // Initialize configuration, logging, authentication await initializeContext(thisCommand); }) .hook('postAction', async () => { // Cleanup, final logging, metrics await cleanupContext(); }); ``` ### 2. Command Layer Each command implements a standardized interface with consistent error handling: ```typescript // commands/regulation.ts export const regulation = { async action(action: string, options: RegulationOptions): Promise { try { // 1. Input validation const validatedOptions = await validateRegulationOptions(action, options); // 2. Authorization check await authorizeRegulationAction(action, validatedOptions); // 3. Business logic execution const result = await executeRegulationAction(action, validatedOptions); // 4. Output formatting await formatAndDisplayResult(result, options); // 5. Audit trail if (options.proof) { const proof = await generateRegulationProof(action, result); console.log(`Proof: ${proof}`); } } catch (error) { throw new RegulatoryError(`Regulation ${action} failed: ${error.message}`); } } }; ``` ### 3. Business Logic Layer #### Regulatory Engine Central engine for regulation lifecycle management: ```typescript class RegulatoryEngine { async createRegulation(data: RegulationData): Promise { // Generate unique regulation ID const id = await this.generateRegulationId(); // Create regulation with metadata const regulation = new Regulation({ id, ...data, status: RegulationState.DRAFT, version: '1.0.0', created: new Date().toISOString(), updated: new Date().toISOString() }); // Validate regulation content await this.validateRegulationContent(regulation); // Store regulation await this.regulationStore.save(regulation); // Emit event this.eventEmitter.emit('regulation.created', regulation); return regulation; } async updateRegulation(id: string, updates: Partial): Promise { const regulation = await this.regulationStore.findById(id); if (!regulation) { throw new RegulationNotFoundError(id); } // Check if updates are allowed in current state this.validateStateTransition(regulation.status, updates.status); // Apply updates const updatedRegulation = { ...regulation, ...updates, updated: new Date().toISOString() }; // Save changes await this.regulationStore.update(id, updatedRegulation); this.eventEmitter.emit('regulation.updated', updatedRegulation); return updatedRegulation; } } ``` #### Publication System Multi-channel publication with scheduling: ```typescript class PublicationSystem { private channels: Map = new Map(); constructor() { this.channels.set('official-gazette', new OfficialGazetteChannel()); this.channels.set('website', new WebsiteChannel()); this.channels.set('api', new APIChannel()); this.channels.set('email', new EmailChannel()); } async publishRegulation( regulation: Regulation, options: PublicationOptions ): Promise { // Create publication record const publication = new Publication({ id: generatePublicationId(), regulationId: regulation.id, effectiveDate: options.effectiveDate, channels: options.channels, status: options.draft ? 'draft' : 'published', publishedDate: new Date().toISOString() }); // Publish through selected channels const results = await Promise.allSettled( options.channels.map(channelName => this.publishToChannel(channelName, regulation, publication) ) ); // Track notifications sent publication.notificationsSent = results .filter(result => result.status === 'fulfilled') .reduce((count, result) => count + (result.value?.notificationCount || 0), 0); await this.publicationStore.save(publication); return publication; } } ``` #### Enforcement Framework Graduated enforcement with penalty calculation: ```typescript class EnforcementFramework { private penaltyMatrix: Map = new Map(); async createEnforcementAction( regulation: Regulation, entity: string, options: EnforcementOptions ): Promise { // Calculate penalty based on action type and severity const penalty = this.calculatePenalty(options.action, options.severity, regulation.type); // Determine deadline based on action type const deadline = this.calculateDeadline(options.action); const enforcement = new EnforcementAction({ id: generateEnforcementId(), regulationId: regulation.id, entityId: entity, action: options.action, severity: options.severity, penalty, status: 'active', created: new Date().toISOString(), deadline }); await this.enforcementStore.save(enforcement); // Notify entity await this.notificationService.notifyEnforcement(enforcement); return enforcement; } private calculatePenalty(action: string, severity: string, regulationType: string): string { const schedule = this.penaltyMatrix.get(`${action}_${severity}_${regulationType}`); return schedule ? schedule.calculatePenalty() : '$0'; } } ``` #### Audit System Comprehensive compliance auditing: ```typescript class AuditSystem { async conductAudit(options: AuditOptions): Promise { const audit = new Audit({ id: generateAuditId(), period: options.period, regulation: options.regulation, depth: options.depth, generated: new Date().toISOString() }); // Collect entities in scope const entities = await this.getAuditScope(options); // Perform compliance checks const findings: AuditFinding[] = []; for (const entity of entities) { const entityFindings = await this.auditEntity(entity, options); findings.push(...entityFindings); } // Calculate compliance metrics const complianceRate = this.calculateComplianceRate(entities, findings); // Categorize findings by severity const summary = this.categorizeFin dings(findings); audit.entitiesAudited = entities.length; audit.complianceRate = complianceRate; audit.findings = findings; audit.summary = summary; await this.auditStore.save(audit); return audit; } private async auditEntity(entity: Entity, options: AuditOptions): Promise { const findings: AuditFinding[] = []; // Check KYC compliance if (options.regulation === 'all' || options.regulation.includes('kyc')) { const kycFinding = await this.checkKYCCompliance(entity); if (kycFinding) findings.push(kycFinding); } // Check AML compliance if (options.regulation === 'all' || options.regulation.includes('aml')) { const amlFinding = await this.checkAMLCompliance(entity); if (amlFinding) findings.push(amlFinding); } return findings; } } ``` ## Command Processing ### 1. Command Lifecycle ``` Input → Parsing → Validation → Authorization → Execution → Output → Audit ↓ ↓ ↓ ↓ ↓ ↓ ↓ Args → Options → Validated → Authorized → Business → Format → Proof Data Context Logic Data ``` ### 2. Validation Pipeline ```typescript class ValidationPipeline { private validators: Validator[] = []; addValidator(validator: Validator): void { this.validators.push(validator); } async validate(data: any, context: ValidationContext): Promise { const results: ValidationResult[] = []; for (const validator of this.validators) { const result = await validator.validate(data, context); results.push(result); if (!result.isValid && result.severity === 'critical') { break; // Stop on critical errors } } return this.aggregateResults(results); } } class RegulationTitleValidator implements Validator { async validate(data: RegulationData): Promise { if (!data.title || data.title.trim().length === 0) { return { isValid: false, severity: 'critical', message: 'Regulation title is required', field: 'title' }; } if (data.title.length > 200) { return { isValid: false, severity: 'warning', message: 'Regulation title should be under 200 characters', field: 'title' }; } return { isValid: true }; } } ``` ### 3. Authorization System ```typescript class AuthorizationSystem { async authorize(action: string, resource: string, context: AuthContext): Promise { // Check government authority if (!this.isValidGovernmentEntity(context.governmentId)) { throw new UnauthorizedError('Invalid government entity'); } // Check jurisdiction if (!this.hasJurisdiction(context.jurisdiction, resource)) { throw new UnauthorizedError('Insufficient jurisdiction authority'); } // Check action permissions const permissions = await this.getPermissions(context.governmentId); if (!permissions.includes(action)) { throw new UnauthorizedError(`Action '${action}' not permitted`); } return true; } private isValidGovernmentEntity(governmentId: string): boolean { const validEntities = [ 'us-treasury', 'sec', 'cftc', 'fincen', 'eu-commission', 'bafin', 'fca', 'esma' ]; return validEntities.includes(governmentId); } } ``` ## Regulatory Engine ### 1. Regulation Lifecycle Management ```typescript class RegulationLifecycle { private stateMachine: RegulationStateMachine; private workflowEngine: WorkflowEngine; async transitionRegulation( regulation: Regulation, newState: RegulationState, context: TransitionContext ): Promise { // Validate state transition if (!this.stateMachine.canTransition(regulation.status, newState)) { throw new InvalidStateTransitionError(regulation.status, newState); } // Execute pre-transition hooks await this.executePreTransitionHooks(regulation, newState, context); // Update regulation state regulation.status = newState; regulation.updated = new Date().toISOString(); // Save changes await this.regulationStore.update(regulation.id, regulation); // Execute post-transition hooks await this.executePostTransitionHooks(regulation, newState, context); // Emit state change event this.eventEmitter.emit('regulation.state_changed', { regulation, previousState: context.previousState, newState }); return regulation; } } ``` ### 2. Content Management ```typescript class RegulationContentManager { async validateContent(content: string, type: RegulationType): Promise { const validator = this.getValidatorForType(type); const result = await validator.validate(content); return { isValid: result.errors.length === 0, errors: result.errors, warnings: result.warnings, suggestions: result.suggestions }; } async generateContent(template: string, parameters: Record): Promise { const templateEngine = new RegulationTemplateEngine(); return templateEngine.render(template, parameters); } } ``` ## Publication System ### 1. Multi-Channel Architecture ```typescript abstract class PublicationChannel { abstract name: string; abstract publish(regulation: Regulation, publication: Publication): Promise; abstract verify(publicationId: string): Promise; } class OfficialGazetteChannel extends PublicationChannel { name = 'official-gazette'; async publish(regulation: Regulation, publication: Publication): Promise { // Format regulation for official gazette const formattedContent = await this.formatForGazette(regulation); // Submit to gazette system const submissionId = await this.gazetteAPI.submit({ content: formattedContent, effectiveDate: publication.effectiveDate, category: regulation.type }); return { success: true, channelId: submissionId, notificationCount: await this.gazetteAPI.getSubscriberCount() }; } } class WebsiteChannel extends PublicationChannel { name = 'website'; async publish(regulation: Regulation, publication: Publication): Promise { // Generate web-friendly format const webContent = await this.formatForWeb(regulation); // Publish to government website const pageId = await this.websiteAPI.createPage({ title: regulation.title, content: webContent, category: regulation.type, publishDate: publication.publishedDate, effectiveDate: publication.effectiveDate }); return { success: true, channelId: pageId, url: `https://regulations.gov/regulation/${regulation.id}`, notificationCount: 0 // Web publishing doesn't send direct notifications }; } } ``` ### 2. Scheduling System ```typescript class PublicationScheduler { private scheduledPublications: Map = new Map(); async schedulePublication( regulation: Regulation, effectiveDate: Date, options: PublicationOptions ): Promise { const scheduled = new ScheduledPublication({ id: generateScheduleId(), regulationId: regulation.id, effectiveDate, options, status: 'scheduled' }); this.scheduledPublications.set(scheduled.id, scheduled); // Set up timer for publication const delay = effectiveDate.getTime() - Date.now(); setTimeout(() => this.executeScheduledPublication(scheduled.id), delay); } private async executeScheduledPublication(scheduleId: string): Promise { const scheduled = this.scheduledPublications.get(scheduleId); if (!scheduled) return; try { const regulation = await this.regulationStore.findById(scheduled.regulationId); await this.publicationSystem.publishRegulation(regulation, scheduled.options); scheduled.status = 'published'; } catch (error) { scheduled.status = 'failed'; scheduled.error = error.message; } } } ``` ## Enforcement Framework ### 1. Violation Detection ```typescript class ViolationDetector { private rules: ComplianceRule[] = []; async detectViolations(entity: Entity, regulations: Regulation[]): Promise { const violations: Violation[] = []; for (const regulation of regulations) { const applicableRules = this.rules.filter(rule => rule.appliesTo(entity, regulation) ); for (const rule of applicableRules) { const result = await rule.evaluate(entity); if (!result.compliant) { violations.push(new Violation({ id: generateViolationId(), entityId: entity.id, regulationId: regulation.id, ruleId: rule.id, severity: result.severity, description: result.description, evidence: result.evidence, detected: new Date().toISOString() })); } } } return violations; } } class KYCComplianceRule implements ComplianceRule { id = 'kyc-verification-required'; appliesTo(entity: Entity, regulation: Regulation): boolean { return regulation.type === 'financial' && entity.type === 'financial-institution'; } async evaluate(entity: Entity): Promise { const kycData = await this.getKYCData(entity.id); if (!kycData || !kycData.verified) { return { compliant: false, severity: 'high', description: 'KYC verification incomplete or missing', evidence: { kycStatus: kycData?.status || 'not_started' } }; } return { compliant: true }; } } ``` ### 2. Penalty Calculation ```typescript class PenaltyCalculator { private schedules: Map = new Map(); calculatePenalty(violation: Violation): PenaltyAssessment { const scheduleKey = `${violation.regulationType}_${violation.severity}`; const schedule = this.schedules.get(scheduleKey); if (!schedule) { throw new PenaltyScheduleNotFoundError(scheduleKey); } const basePenalty = schedule.getBasePenalty(); const multiplier = this.getMultiplier(violation); const adjustments = this.getAdjustments(violation); const totalPenalty = (basePenalty * multiplier) + adjustments; return new PenaltyAssessment({ violationId: violation.id, basePenalty, multiplier, adjustments, totalPenalty, currency: 'USD', calculated: new Date().toISOString() }); } private getMultiplier(violation: Violation): number { // Factors that increase penalty let multiplier = 1.0; // Repeat offender if (violation.entityHistory.violationCount > 0) { multiplier += 0.5 * violation.entityHistory.violationCount; } // Market impact if (violation.marketImpact === 'high') { multiplier += 1.0; } // Willful violation if (violation.isWillful) { multiplier += 2.0; } return Math.min(multiplier, 5.0); // Cap at 5x } } ``` ## Audit System ### 1. Audit Engine ```typescript class AuditEngine { private auditors: Map = new Map(); async conductComprehensiveAudit(options: AuditOptions): Promise { const auditPlan = await this.createAuditPlan(options); const results: AuditFinding[] = []; for (const procedure of auditPlan.procedures) { const auditor = this.auditors.get(procedure.type); if (!auditor) { throw new AuditorNotFoundError(procedure.type); } const findings = await auditor.execute(procedure); results.push(...findings); } return this.compileAuditResult(results, auditPlan); } private async createAuditPlan(options: AuditOptions): Promise { const plan = new AuditPlan(); // Add standard procedures based on regulation type if (options.regulation === 'all' || options.regulation.includes('financial')) { plan.addProcedure(new KYCAuditProcedure()); plan.addProcedure(new AMLAuditProcedure()); plan.addProcedure(new TransactionMonitoringProcedure()); } // Add depth-specific procedures if (options.depth === 'comprehensive') { plan.addProcedure(new DocumentationReviewProcedure()); plan.addProcedure(new SystemSecurityAuditProcedure()); } return plan; } } class KYCAuditor implements Auditor { async execute(procedure: AuditProcedure): Promise { const findings: AuditFinding[] = []; const entities = await this.getEntitiesInScope(procedure.scope); for (const entity of entities) { const kycData = await this.getKYCData(entity.id); // Check completeness if (!this.isKYCComplete(kycData)) { findings.push(new AuditFinding({ entityId: entity.id, type: 'kyc_incomplete', severity: 'medium', description: 'KYC documentation incomplete', recommendation: 'Complete missing KYC documentation within 30 days' })); } // Check validity if (!this.isKYCValid(kycData)) { findings.push(new AuditFinding({ entityId: entity.id, type: 'kyc_invalid', severity: 'high', description: 'KYC documentation invalid or expired', recommendation: 'Update KYC documentation immediately' })); } } return findings; } } ``` ### 2. Report Generation ```typescript class AuditReportGenerator { async generateReport(audit: AuditResult, format: string): Promise { const generator = this.getGeneratorForFormat(format); return generator.generate(audit); } } class PDFAuditReportGenerator implements ReportGenerator { async generate(audit: AuditResult): Promise { const document = new PDFDocument(); // Title page this.addTitlePage(document, audit); // Executive summary this.addExecutiveSummary(document, audit); // Detailed findings this.addDetailedFindings(document, audit); // Recommendations this.addRecommendations(document, audit); // Appendices this.addAppendices(document, audit); const buffer = await this.finalizePDF(document); return { format: 'pdf', content: buffer, filename: `audit-report-${audit.period}-${Date.now()}.pdf`, size: buffer.length }; } } ``` ## Security Model ### 1. Cryptographic Proofs ```typescript class ProofGenerator { async generateRegulationProof(action: string, data: any): Promise { const timestamp = new Date().toISOString(); const payload = { action, data: this.sanitizeData(data), timestamp, nonce: crypto.randomBytes(16).toString('hex'), authority: process.env.GOVERNMENT_ID, jurisdiction: process.env.JURISDICTION }; // Create hash chain const dataHash = crypto.createHash('sha256').update(JSON.stringify(data)).digest('hex'); const actionHash = crypto.createHash('sha256').update(action).digest('hex'); const combinedHash = crypto.createHash('sha256') .update(dataHash + actionHash + timestamp) .digest('hex'); return `pact-proof-${combinedHash.substring(0, 16)}`; } async verifyProof(proof: string, originalData: any): Promise { // Implementation for proof verification return true; // Simplified } } ``` ### 2. Access Control ```typescript class AccessControlManager { private permissions: Map = new Map(); async checkPermission( governmentId: string, action: string, resource: string ): Promise { const userPermissions = this.permissions.get(governmentId) || []; return userPermissions.some(permission => permission.action === action && permission.resource === resource && this.isPermissionValid(permission) ); } private isPermissionValid(permission: Permission): boolean { return permission.expiresAt > new Date() && permission.status === 'active'; } } ``` ### 3. Data Protection ```typescript class DataProtectionManager { async encryptSensitiveData(data: any): Promise { const key = await this.getEncryptionKey(); const cipher = crypto.createCipher('aes-256-cbc', key); let encrypted = cipher.update(JSON.stringify(data), 'utf8', 'hex'); encrypted += cipher.final('hex'); return { data: encrypted, algorithm: 'aes-256-cbc', encrypted: true }; } async anonymizeData(data: any): Promise { const anonymized = { ...data }; // Remove PII fields delete anonymized.name; delete anonymized.email; delete anonymized.phone; // Hash identifiers if (anonymized.id) { anonymized.id = crypto.createHash('sha256').update(anonymized.id).digest('hex'); } return anonymized; } } ``` ## Performance Considerations ### 1. Caching Strategy ```typescript class RegulationCache { private cache = new Map(); private readonly TTL = 5 * 60 * 1000; // 5 minutes async get(key: string): Promise { const entry = this.cache.get(key); if (!entry || entry.expiresAt < Date.now()) { this.cache.delete(key); return null; } return entry.data; } async set(key: string, data: any, ttl?: number): Promise { this.cache.set(key, { data, expiresAt: Date.now() + (ttl || this.TTL) }); } } ``` ### 2. Batch Processing ```typescript class BatchProcessor { async processRegulations( regulations: Regulation[], operation: (reg: Regulation) => Promise ): Promise { const batchSize = 10; for (let i = 0; i < regulations.length; i += batchSize) { const batch = regulations.slice(i, i + batchSize); await Promise.all( batch.map(regulation => operation(regulation)) ); // Small delay between batches await new Promise(resolve => setTimeout(resolve, 100)); } } } ``` ## Extensibility ### 1. Plugin Architecture ```typescript interface RegulatoryPlugin { name: string; version: string; initialize(system: RegulatorySystem): void; commands?: Command[]; hooks?: Hook[]; channels?: PublicationChannel[]; } class PluginManager { private plugins: RegulatoryPlugin[] = []; async loadPlugin(pluginPath: string): Promise { const plugin = await import(pluginPath); this.registerPlugin(plugin.default); } registerPlugin(plugin: RegulatoryPlugin): void { this.plugins.push(plugin); plugin.initialize(this.system); // Register commands if (plugin.commands) { plugin.commands.forEach(cmd => this.commandRegistry.register(cmd)); } // Register publication channels if (plugin.channels) { plugin.channels.forEach(channel => this.publicationSystem.addChannel(channel)); } } } ``` ### 2. Custom Validators ```typescript interface CustomValidator { name: string; validate(data: any, context: ValidationContext): Promise; } class ValidatorRegistry { private validators = new Map(); register(validator: CustomValidator): void { this.validators.set(validator.name, validator); } async validate(validatorName: string, data: any): Promise { const validator = this.validators.get(validatorName); if (!validator) { throw new ValidatorNotFoundError(validatorName); } return validator.validate(data, this.createContext()); } } ``` --- This architecture documentation provides a comprehensive overview of the PACT Gov CLI system design, enabling government agencies and developers to understand, implement, and extend the regulatory management capabilities effectively.
