Profile Investigator

Purpose

Deep diagnostic profile exploration. Answers questions like:

• "Why is this user in segment X?"
• "Why isn't this user in segment Y?"
• "What happened to this user?" (data lineage)
• "What does this user look like?" (full profile + memberships)

Goes beyond basic profile lookup by cross-referencing profile data against segment FilterQL to show exactly which conditions match or fail.

Environment

Requires authenticated API access. See ../references/auth.md for credential resolution.

Inputs

• Identity field and value (e.g., email, user@example.com)
• Segment name or ID (for membership diagnosis)
• Or a diagnostic question in natural language
