Support ticket transcripts

Identifies support ticket conversation transcripts in security and access control contexts. Enforcement requires timestamped requester/agent message turns; ticket, help-desk, and service-desk references without conversational structure remain discovery inventory.

Known false positives

Authentication-related terminology in software documentation, security training materials, or system architecture descriptions without actual credentials. Mitigation: Require proximity to credential-specific patterns (API keys, connection strings, tokens) rather than general security terminology.
Code snippets and configuration examples containing credential-related keywords or placeholder values in developer documentation. Mitigation: Check for common placeholder patterns (example.com, localhost, 0000) and documentation file types to reduce false positives from technical writing.
