Known false positives

• Variable-length numeric sequences (6-10 digits) are extremely common and will match many non-identity numbers. Mitigation: Require corroborative evidence keywords such as "cédula" or "ciudadanía" within the proximity window. This pattern has a high false positive rate without keyword context.
• 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.
