* AI Security Service Tests

|
* ADR-071: Security Hardening — Tasks 4-7
|
|
*
|
|
* BEHAVIOR: AI agent security with input sanitization, prompt injection detection,
|
|
* output redaction, and audit logging
|
|
*
|
|
* Tests for:
|
|
* - sanitizeInput(message) - returns {sanitized: string, threats: string[]}
|
|
* - detectInjection(message) - returns {detected: boolean, patterns: string[]}
|
|
* - escapeSpecialTokens(message) - escapes LLM tokens
|
|
* - redactSecrets(text) - redacts API keys, tokens, passwords
|
|
* - redactPII(text) - redacts email, phone, credit cards
|
|
* - redactOutput(text) - combined redaction (secrets + PII)
|
|
* - hashContent(content) - SHA256 hash for privacy
|
|
* - logAuditEntry(entry) - records to ai_audit_log table
|
