Override cost is graduated per rule: one click for ordinary warns, typed justification for crown-jewel and classified matches. Every override is logged against the AD identity.
What is real here
- NRIC prefix-weighted checksum with per-series letter tables
- MyKad contextual validation — there is no check digit to verify
- NIK province codes and the +40 day-offset for women
- Thai mod-11 check digit; Vietnamese province and century/gender structure
- Luhn, IBAN mod-97, secret patterns and Shannon-entropy scoring
- Action ladder, rollout-stage capping, and exception precedence
What is not
- Model classification — it runs on the appliance GPU
- Exact Data Match against your real records; the crown-jewel sample is a stand-in for salted-hash matching
- Document fingerprinting and classification-label reads
- Code-switched multilingual classification
