Known false positives
- Nine-digit numeric sequences with optional separators may match financial or administrative reference numbers. Mitigation: Require corroborative evidence keywords such as "RG" or "registro geral" within the proximity window.
- In multiple languages, similar terminology used in formal or administrative contexts (education, professional documentation) that does not constitute sensitive data collection. Mitigation: Layer with additional contextual signals such as structured identifiers, form fields, or database column headers to distinguish sensitive records from general references.
