What Sombra detects

Sombra extends Presidio's default recognizers. Everything Presidio already detects keeps working — names via spaCy NER, e-mails, phone numbers, URLs, locations — and Sombra adds the Brazilian patterns that are missing:

Entity	Example	Confidence
SOMBRA_CPF	123.456.789-00	0.95 (1.00 with context)
SOMBRA_CEP	80000-000	0.95
SOMBRA_CNPJ	12.345.678/0001-90	0.95
SOMBRA_ADDRESS	Rua das Flores, 123	0.75
PERSON	João (spaCy NER)	0.85
LOCATION	Curitiba (spaCy NER)	0.85

PERSON and LOCATION come from Presidio's built-in spaCy NER. The SOMBRA_* entities are Sombra's own pattern-based recognizers.

How masking looks

Detected tokens are replaced by masks in the anonymizer, e.g.:

Consult my order in the name of João, CPF <SOMBRA_CPF>, living in Curitiba, CEP <SOMBRA_CEP>.
