## NIT verification

The NIT verifier (DV) of every entry in [`known-domains.json`](known-domains.json)
was computed against the DIAN modulo-11 algorithm
([`src/normalizers/nit-co.ts`](../../../src/normalizers/nit-co.ts)) with
weights `[41, 37, 29, 23, 19, 17, 13, 7, 3]` applied left-to-right.

Entries are confidence-banded:
- `0.95–1.0` · NIT body sourced from a published canonical reference
  (DIAN RUT, Superintendencia disclosures, official company filings).
- `0.7–0.85` · NIT body inferred from public records; DV computed locally.
- `0.5–0.6` · NIT body is a placeholder; the high-confidence facts are the
  domain and sector classification.
