🟡 MEDIUM: Replace print statements with structured logging

[arkavo-com]

Problem

The codebase uses print() statements for logging instead of structured logging.

Examples Found

// AuthenticationManager.swift
print("Error getting public key data: \(error!.takeRetainedValue() as Error)")

// ArkavoMessageRouter.swift
print("Error: \(error)")

// Multiple files
print("Debug: ...")

Issues

1. No log levels - Cannot filter by severity
2. No context - Missing file, line, function info
3. Production exposure - Sensitive data may be logged
4. No aggregation - Cannot collect logs for debugging

Note

A SecureLogger.swift utility exists but is not consistently used.

Solution

1. Audit all print() statements
2. Replace with SecureLogger calls
3. Add appropriate log levels (debug, info, warning, error)
4. Ensure sensitive data is redacted in production

Acceptance Criteria

• Zero print() statements in production code
• All logs use SecureLogger
• Log levels appropriate for each message
• Sensitive data redacted
