# Mistral Data Handling ## Overview Manage data flows through Mistral AI APIs with PII redaction, audit logging, fine-tuning dataset sanitization, and conversation retention policies. Mistral's data policy: API requests on La Plateforme are **not** used for training by default. Self-deployed models give full data sovereignty. ## Prerequisites - Mistral API key configured - Understanding of data classification (PII, PHI, PCI) - Logging infrastructure for audit trails ## Instructions ### Step 1: PII Redaction Before API Calls ```typescript interface RedactionRule { pattern: RegExp; replacement: string; type: string; } const PII_RULES: RedactionRule[] = [ { pattern: /\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}\b/gi, replacement: '[EMAIL]', type: 'email' }, { pattern: /\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g, replacement: '[PHONE]', type: 'phone' }, { pattern: /\b\d{3}-\d{2}-\d{4}\b/g, replacement: '[SSN]', type: 'ssn' }, { pattern: /\b\d{4}[\s-]?\d{4}[\s-]?\d{4}[\s-]?\d{4}\b/g, replacement: '[CARD]', type: 'credit_card' }, { pattern: /\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/g, replacement: '[IP]', type: 'ip_address' }, ]; function redactPII(text: string): { cleaned: string; redactions: string[] } { const redactions: string[] = []; let cleaned = text; for (const rule of PII_RULES) { const matches = cleaned.match(rule.pattern); if (matches) { redactions.push(...matches.map(m => `${rule.type}: ${m.slice(0, 4)}***`)); cleaned = cleaned.replace(ru...
