## Capabilities

anonym.legal provides 5 anonymization operators: Replace (irreversible), Redact (irreversible), Mask (irreversible), Hash/SHA-256/SHA-512 (deterministic pseudonymization per GDPR WP29), Encrypt (reversible pseudonymization per GDPR Article 4(5), user-controlled keys). Customization: user-defined custom entity types (regex-based or AI-generated patterns for internal identifiers, project codes, and proprietary data formats), reusable presets bundling operator + entity configurations, and user-controlled substitution values inside the Replace operator. Detection: hybrid regex + NLP engine (spaCy 24 models, Stanza 6 models, XLM-RoBERTa transformer). The automated suite is under revision following an internal audit; pass counts reflect execution, not a correctness guarantee.

## Testing

anonym.legal runs automated checks over auth, PII detection (48 languages, spaCy/Stanza/XLM-RoBERTa), anonymization (5 operators), decrypt roundtrips, batch, entities, presets, settings, API security (35 tests), tokens, Lighthouse (100/100/100), 48 languages + RTL, cross-browser (Chromium/Firefox/WebKit/Mobile Chrome), full API route coverage, SEO/AEO/GEO audit, real UI click-through. The suite is under revision following an internal audit that found coverage gaps in the batch/file-handling and decrypt-roundtrip milestones; treat pass counts as execution stats, not a correctness guarantee.
